Report of Independent Auditors To the Executive Board of Energy Northwest We have audited the accompanying balance sheet of Energy Northwest aand the related individual balance sheets of Energy Northwest's business units and internal service fund as of June 30, 2O005, and the related statement of operations and fund equity and of cash flows for the yaear then ended. Energy Northwest's business units include the Columbia Generating Station, Packwood Lake Hydroelectrc Project, Nuclearn Project-No. 1, Nuclear Project No. 3, the Business Development Fund, Grays Harbor Energy Facility, and the' Nine Canyon Wind. Project. These basic financial statements are the responsibility of Energy Northwest's 'rariagement. Our responsibility is to express an opinion on these basic financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America.

Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the basic financial statements are free from material misstatement.

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the basic financial statements referred to above present fairly, in all material respects, the financial position of Energy Northwest and Energy Northwest's business units and internal service fund as of June 30, 2005, and the results of their operations and cash flows for the years theni ended in conformity with accounting principles generally accepted in the United States of America.

The Management's Discussion and Analysis listed in the table of contents is not a required part of the basic financial statements but is supplementary information required bythe Governmental Accounting Standards Board. We have applied certain limited procedures, which consisted, principally of inquiries of management regarding the methods of measurement and presentation of the required supplerrmntary information. However, we did not audit the information and express no opinion on it.

Management's Discussion and Analysis Energy Northwest is a municipal corporation and joint operating agency of the State of Washington. Each Energy Northwest Business Unit is financed and accounted for separately from all other current or future business assets. The following discussion and analysis is organized by Business Unit.

The management discussion and analysis of the financial performance and activity is provided as an introduction and to aid in comparing the basic financial statements for the Fiscal Year ended June 30, 2005 with the basic financial statements for the Fiscal Year ended June 30, 2004. Energy Northwest has adopted accounting policies and principles that are in accordance with Generally Accepted Accounting Principles (GAAP) in the United States of America. Energy Northwest applies GAAP to the extent it does not conflict with Governmental Accounting Standards Board (GASB) standards (see Note B to the Financial Statements).

The financial statements include the Balance Sheets; Statements of Operations and Fund Equity; Statements of Cash Flows; Supplementary Schedules of Outstanding Long-Term Debt and Debt Service Requirements; and Notes to Financial Statements for each of the Business Units. The Balance Sheets present the financial position of each Business Unit based on an accrual basis.

The Balance Sheets report information about construction work in progress, amount of resources and obligations, restricted accounts and due toldue from balances (see Note B to the financial statements) that reflect what is owed by each Business Unit.

The Statements of Operations and Fund Equity reports information relating to all expenses, revenues and equity that reflect the results of each Business Unit and its related activities over the course of the Fiscal Year. The information provided aids in benchmarking activities, conducting comparisons to evaluate

progress, and determining whether the Business Unit has successfully recovered its costs.

The Statements of Cash Flows reflects cash receipts and disbursements and net -changes resulting from operating, financing and investment activities. The statements provide insight into what generates cash, where the cash comes from, and what it was used for.

The Notes to Financial Statements present disclosures that contribute to the understanding of the material presented in the financial statements. This includes but is not limited to, accounting policies, significant balances and activities, materials risks, commitments and obligations and subsequent events, if applicable.

Columbia Generating Station The Columbia Generating Station Nuclear Power Plant (Columbia) is owned by Energy Northwest and its Participants and operated by Energy Northwest.

The Plant is a 1,153 megawatt (MWe) boiling water nuclear power station located on the Department of Energy's Hanford Reservationr north of Richland, Washington.

Columbia Generating Statiorf (CGS) completed more than a year of continuous generation, setting a station record for operating a total of 393 days extending partially into Fiscal Year (FY) 2005 (July 3, 2003 to July 30, 2004).

Columbia produced 7,599 GWh of electricity in FY 2005, as compared to 9,520 GWh of electricity in FY Year 2004, which included economic dispatch of 0 GWh and 16 GWh respectively. Columbia successfully completed its second two-year refueling and maintenance outage (R-1 7) in June of 2005. CGS completed R-17 within the 35 day budget with costs totaling $52.9 million.

However there were three forced outages in FY 2005, in addition to the R-17 planned outage, that resulted in the decreased generation levels in FY 2005 from FY 2004 levels.

2,000 4000 6,000 8,000 10,000 Energy Northwest's performance is measured in several ways, including cost of power at Columbia Generating Station. The industry cost of power fluctuates somewhat year to year depending on various factors such as refueling outages and other planned activities.

Columbia Generating Station Cost of Power Cents/kWh 3.50 3.00 2.50 2.00 1.50 1.00 0.50 0.00 on this project in FY 2005 with a two year project cost of

$15.9 million. Other major components of the change in plant and CWIP were upgrades to the Station Security System Computer, which runs all of the security systems inside the protected area of CGS ($5.4 million); Jet Pump Clamps, which modified seals to reduce fatigue and extend continued operation out 20 years past R-1 7

($2.0 million).

Nuclear fuel, net of accumulated amortization, increased $24.1 million from FY 2004 to $126.1 million for FY 2005. During FY 2005, CGS purchased $51.0 million of nuclear fuel, which was offset by current year amortization of $26.9 million. The fuel purchases were associated with the R-18 and R-19 maintenance and refueling planned outages in FY 2007 and FY 2009.

The Restricted Assets Special Funds increased

$65.7 million from FY 2004 levels to $117.2 million in FY 2005. This was due to additional financing for future fuel purchases associated with the two year refueling and maintenance outages and capital improvements. It is expected this increase will supply necessary funding for the next two refueling outages (R-18 and R-19 in FY 2007 and FY 2009). The increase in restricted assets was partially offset by the $19.4 million in Construction fund spending.

The Debt Service Funds increased $11.2 million in FY 2005 to $32.9 million. The increase was due to interest payable being larger in FY 2005 than in FY 2004.

Long-term receivables and current assets remained relatively stable from FY 2004 to FY 2005.

The long term receivable account increased slightly due to an FY 2004 adjustment to a $3.3 million reclassification made for a 1992 Settlement Agreement with a third party. The estimate made in FY 2005 was in anticipation of the R-17 related discounts that would be forthcoming in the next year; however the amounts received in FY 2005 were lower than originally estimated.

.Y 200 Y 200 2001 Balance Sheet Analysis Increase to total Plant in Service and Construction Work In Progress (CWIP) from FY 2004 to FY 2005 was $24.4 million.

The total increase was mostly a result of $15.9 million spent on the Nuclear Regulatory Commission (NRC) Mandated Security Project.

The NRC, after the September 11, 2001 terrorist attacks, mandated heightened security improvements to all nuclear facilities.

These improvements were substantially completed in 2005. Energy Northwest spent $10.3 million www.enerav-northwest.com Annual Report www.enerciv-northwest.corn Annual Report

Costs in Excess of Billings have increased

$69.3 million in FY 2005 from

$494.3 million to

$563.2 million, largely due to refunding current maturities while extending the overall maturities on the refunding debt. In addition, the accumulated decommissioning and site restoration accrued costs are not currently billed to Bonneville Power Administration (BPA). BPA holds and manages a trust fund for the purpose of funding decommissioning and site restoration (see Note B to the financial statements, Decommissioning and Site Restoration).

The balances in these external trust funds are not reflected on Energy Northwest's Balance Sheet.

Long-Term Debt increased $217.6 million in FY 2005 from $2.05 billion to $2.27 billion, which was a result of the FY 2005 Bond Issue. As explained above, in FY 2005, new debt was issued for various COGS construction projects, fuel purchases, as well as being issued as part of the Debt Optimization Plan Debt (see Note E to the financial statements).

Statement of Operations Analysis Columbia Generating Station is a net-billed Project. Energy Northwest recognizes revenues equal to expense for each period on net-billed projects. No net revenues or loss is recognized and no equity is accumulated.

As a whole, the operating revenues and expenses remained relatively the same from FY 2004 to FY 2005, with overall Operating Revenues needed to cover expenditures decreasing slightly from last year.

Four individual components of operating expenses related to the successful completion of R-17 and the three unplanned outages were:

Nuclear Fuel-Decreased from $35.3 million in FY 2004 to $28.6 million in FY 2005; Fuel Disposal Fee-Decreased from $9.0 million in FY 2004 to $7.2 million in FY 2005; Generation tax-Decreased from $3.2 million in FY 2004 to $2.3 million in FY 2005; Operations and Maintenance-Increased from

$129.6 million in FY 2004 to $178.7 million (see R-1 7 costs discussed above) in FY 2005; The first three points were a result of lower generation while the fourth point was a result of increased wages due to R-1 7.

Other major changes in CGS operations were:

Administrative

& General-Decreased from

$21.6 million to $18.6 million reflecting the continuing concerted effort to reduce overall costs for CGS; Decommissioning-Decreased from $43.0 million to $5.4 million because FY 2004 included an increase to the value of the Asset Retirement Obligation (ARO),

which was offset by an increase to Cost in Excess of Billings in compliance vo'ith'the Net Billing Agreement.

The amount is a combination of probable cases for accomplishing the required retirement obligations and their associated probabilities.

The liability will also be increased each year to account for the accretion value of the obligation. This yearly accretion value is the amount represented by the FY 2005 value of $4.8 million. (See Note G

to the financial statements for further explanation).

Other Income and Expense changes are the net effects on Columbia Debt (see Note E to the financial statements).

Investment Income was affected by favorable rates in FY 2005 resulting in an increase of

$2.3 million from FY 2004 income to $4.2 million in FY 2005.

Additionally, interest expense increased slightly in FY2005 from $114.2 million to $116.3 million due to $461.7 million of new debt issued in FY 2004 at a 3.75% to 5.5% interest rate.

Amortization of Bond Discount Expense and Amortization of Bond Refunding netted a decrease in expense of $1.9 as a result of the Bond Refunding issues.

Packwood Lake Hydroelectric Project The Packwood Lake Hydroelectric Project is owned and operated by Energy Northwest. The Project consists of a dam at Packwood Lake and powerhouse 1800 feet below the dam that is located south of Packwood, Washington. Packwood produced 88.31 GWh of electricity in FY 2005 versus 90.03 GWh in FY 2004.

20,000 40.000 60,000 80,000 100,000 Balance Sheet Analysis Current Assets have decreased $.3 million from

$2.3 million in FY 2004 to $2.0 million in FY 2005.

Majority of the decrease was due to timing of power sales.

There were no significant changes to current liabilities other than a decrease in due to other business units of $649K from $682K in FY 2004 to $33K in FY 2005. No new debt was issued and the total debt continues to decrease per the current debt schedules.

As a result of operations, Packwood accrued $338K in excess funding that has been agreed to by participants in October of 2005, to be returned to the Packwood business unit for FY 2006 operating reserves.

Packwood incurred $.6 million in re-licensing costs for FY 2005.

These costs are shown as other deferred charges on the Balance Sheet. The FY 2006 projections are for an additional $.6 million in costs to continue the re-licensing efforts. The Federal Regulatory Commission (FERC) issued a 50-year operating license to Packwood on March 1, 1960. The current license will expire on February 28, 2010.

Statement of Operations Analysis The agreement with Project Participants obligates them to pay annual costs and they receive excess revenues.

Accordingly, Energy Northwest recognizes revenues equal to expenses for each period.

No net revenue or loss is recognizedcland no equity is accumulated. Revenues decreased because of the cost decreases detailed below:

Total Operating Expenses decreased $.7 million, from $1.8 million in FY 2004 to $1.1 million in FY 2005. Major drivers for this change were:

Decrease to Depreciation and Amortization of $.3 million as the majority of the plant assets continue to become completely depreciated Operations and Maintenance, along with Administrative and General expenditures, decr sed,,$.4 rmillion', 4rom $1.4 million in F'g 2O0 to $y1..O mulion in FY 2005.

This Was dire to the deceased operations and maintenance costs ue tb insurance savings and completion of annual outage under budget.

$250 Nuclear Project No. 1 Nuclear Project No. 1, a 1,250 MWe plant, was placed in extended construction delay status in 1982, when it was 65 percent complete.

On May 13, 1994, Energy Northwest's Board of Directors adopted a resolution terminating Nuclear Project No. 1.

In FY 1999, the assets and liabilities of the Hanford Generating Project were consolidated into Nuclear Project No. 1.

The Hanford Generating Project site restoration activities were completed on May 19, 2004.

All funding requirements are net-billed obligations of Nuclear Project No. 1. Energy Northwest wholly owns Nuclear Project No. 1. Termination expenses and debt service costs comprise the activity on Nuclear Project No. 1.

Balance Sheet Analysis Under the debt optimization program, long-term debt increased $4.6 million from $1.961 billion in FY 2004 to $1.966 billion in FY 2005, due to debt restructuring to take advantage of lower interest rates.

Statement of Operations Analysis Investment Income increased $1.2 million from

$1.3 million in FY 2004 to $2.5 million in FY 2005, as rates of return began to increase from historical lows.

Nuclear Project No. 3 Nuclear Project No. 3, a 1,240 MWe plant, was placed in extended construction delay status in 1983, when it was 75 percent complete.

On May 13, 1994, Energy Northwest's Board of Directors adopted a

resolution terminating Nuclear Project No. 3.

Energy Northwest is no longer responsible for any site restoration costs as they were transferred with the assets to the Satsop Redevelopment Project (see Note F). The debt service related activities remain and are net-billed.

Balance Sheet Analysis Under the debt optimization program, long-term debt was increased $24.7 million from $1.790 billion in FY 2004 to $1.814 million in FY 2005 due to debt restructuring to take advantage of lower interest rates.

Statement of Operations Analysis Investment Income increased $1.0 million, from

$0.9 million in FY 2004 to $1.9 million in FY 2005, as rates of return began to increase from historical lows.

Business Development Fund The Business Development Fund (BDF) was created by Executive Board Resolution No. 1006 in April 1997, for the purpose of holding, administering, disbursing, and accounting for Energy Northwest costs and revenues generated from engaging in new energy business opportunities.

The BDF is managed as an enterprise fund.

Three business sectors have been created within the fund:

General Services, Generation, and Professional Services.

Each sector may have one or more programs that are managed as a unique business activity. A fourth business sector, Business Unit Support, has been created to capture costs associated with developing programs.

9 www.ener v-northwest.com Annual Report C _

Statement of Operations Analysis Operating Revenues in FY 2005 totaled

$8.1 million as compared to FY 2004 revenues of

$14.7 million, a decrease of $6.6 million. The Department of Energy (DOE) and Energy Northwest had an agreement for the completion of restoration and cleanup of the Hanford Generating Project. Under the agreement DOE would be billed for 50% of the restoration and cleanup efforts.

The project was completed in FY 2004 with Energy Northwest recognizing revenue of $3.8M.

The reduction in intra-company business was the other driver to decreased revenues.

Total operating revenues decreased 45% in FY 2005; however net revenues for the FY 2005 showed a

$697K loss as compared to a $987K loss in FY 2004.

Other Income and Expenses includes $2.4 million of Energy Business Services overhead that were credited to this account. The offset debit to this entry resides as an operating expense. Other income and expenses, less these overheads, was approximately $0.6 million.

Energy Northwest was created to enable Washington public power utilities and municipalities to build and operate generation projects. Three of Energy Northwest's Research and Investigation business projects, BioEnergy Solutions, Wind Mining and Integrated Gasification Combined Cycle (IGCC), accounted for

$1.1 million in expenditures with no revenues.

Energy BioEnergy Solutions is a business line of Energy Northwest that in FY 2005 worked on a full-scale biomass power test unit at a dairy farm near Pasco, Washington which was unable to meet expectations for biogas production. The business line is in the process of evaluating options for moving forward.

In FY 2005, approximately $0.4 million was expended on developing this project.

Wind Mining efforts continued in FY 2005 with approximately $0.3 million being expended. These efforts are to explore, site and demonstrate wind resources for potential new wind sites.

Initial investigation into developing an Integrated Gasification Combined Cycle; (IGCC) project was kicked off in FY 2005, with Approximately $0.4 million expended.

In July 2005, Enetgy Northwe~sts Board of Directors passed a resolution to pursue Kpermitting and possible construction of an Integrated Gasification Combined Cycle (IGCC) power plant in western Washington. The proposal calls for a 600 MW power plant, designed to operate on a

'synthesis gas" with regulated emissions similar to a natural gas plant. The clean-buming synthesis gas can be produced by gasifying rather than burning a variety of carbon-based feed stocks including petroleum coke and coal. Initial operation of the completed plant could be as early as 2011.

The Business Development Fund receives contributions from the Internal Service Fund to cover cash needs during this startup period. Initial startup costs are not expected to be paid back and are shown as contributions. As an operating business unit, requests can be made to fund incurred operating expenses.

In FY 2005, the Business Development Fund received coritributions (transfers) of $1.7 million.

Grays Harbor Energy Facility The Grays Harbor Energy Facility Frojectf was established in July 1990 to collect advances and contributions to pay the costs of investigating new, generating' projects,' including the feasibility of a combustion turbine near Satsop, Washington. The project purpose was amended during FY 2002 to include the operation and maintenance of a 'gas ;ficed combustion turbine placed on the Grays Harbor site (owned by Duke Energy Grays Harbor LLC) and included the option to purchase up to 50MW of power generated by the facility.

10 www.enerav-northwest.com A~nnual Report

In September 2002, due to market conditions, Duke Energy North America (DENA) placed the project in "Construction Suspension."

In February 2004, DENA announced it has no intention to complete the facility with their own funds.

Per the agreement with DENA, if construction was not restarted by August 31, 2004, such that the project reaches substantial completion eleven months later, or if the project fails to achieve commercial operation by December 31, 2005, Energy Northwest may request payment of approximately

$5 million and dissolution of the O&M contract.

Energy Northwest received this payment in March of 2005. Remaining cash and investments were transferred to the Internal Service Fund - Performance Fee Account in June of 2005. All obligations of this fund have been completed and the fund was dissolved by the Executive Board in July 2005.

Statement of Operations Analysis Non-Operating revenues were $0.4 million and

$4.9 million for FY 2004 and FY 2005 respectively, with the increase due to the dissolution of O&M contract discussed above.

Nine Canyon Wind Project The Nine Canyon Wind Energy Project is owned and operated by Energy Northwest. The Project is located in the Horse Heaven Hills area southwest of Kennewick, Washington.

Electricity generated by the Project is purchased by Pacific Northwest Public Utility Districts whose customers have expressed an interest in purchasing at least a portion of their electricity from green power sources. Each purchaser of Phase I has signed a 22-year power purchase agreement with Energy Northwest and each purchaser of Phase II has signed a 20-year power purchase agreement.

The project is connected to the Bonneville Power Administration transmission grid via a substation and transmission lines constructed by the Benton County Public Utility District.

Phase I of the project, which began commercial operation in September 2002, consists of 37 wind turbines, each with a

maximum generating capacity of approximately 1.3 megawatts of electricity, for a total wind capacity of 48.1 megawatts. Phase II of the project, which was declared operational December 31, 2003, includes an additional 12 wind turbines with an aggregate generating capacity of approximately 15.6 megawatts. The total project generating capability is approximately 63.7 megawatts, which produces enough energy capacity for approximately 26,000 average homes.

Nine Canyon Wind Project produced 154.52 GWh of electricity in FY 2005 versus 138.44 GWh in FY 2004.

Each three-blade turbine consists of a tubular steel tower approximately 200 feet in height, three 100-foot turbine blades attached to a rotor, and a nacelle that houses a generator, gear box and braking mechanism.

Balance Sheet Analysis Receivables increased by $0.7 million corresponding to the increased size of the Renewable Energy Performance Incentive (REPI) payment accrued. The Fund Equity decreased by $2.7 million because the 1 1 www.enerav-northwest.com Annual Report C,6

original plan anticipated operating at a loss in the early years and gradually increasing the rate charged to the purchasers to avoid a large rate increase after the REPI expires in ten years. Reserves that were established are used to facilitate this plan. Long-term debt decreased by

$3.6 million due to the effects of the refinancing of the Phase I debt in January 2005.

Statement of Operations Analysis Operating Revenues increased $0.9M from $5.3M in FY 2004 to $6.2M in FY 2005. This was due to a full year of operation of Phase II of the project in FY 2005 as well as a planned billing increase to project participants of 3%. The project received revenue from the billing of the project purchasers at an average rate of $35.09 per MWh for FY 2005. Energy Northwest has accrued as income (contribution) from the DOE, REPI payments that enable the Nine Canyon Wind Project to receive funds based on generation as it applies to the REPI bill. The REPI was created as part of the Energy Policy Act of 1992 to promote increases in the generation and utilization of electricity from renewable energy sources and to further the advances of renewable energy technologies. This program, authorized under section 1212 of the Energy Policy Act of 1992, provides financial incentive payments for electricity produced and sold by new qualifying renewable energy generation facilities. The Nine Canyon Wind Project recorded a receivable for sixty-eight percent of the applied REPI funding in the amount of $2.3 million for FY 2005. The payment stream and the REPI receipts were projected to cover the total costs over the life of the purchase agreement.

Permanent shortfalls in REPI funding will lead to increases in the billing of the Project participants in order to cover total Project costs.

The agreement with project purchasers anticipates a loss in FY 2006 with additional cash needs being paid from existing project reserve funds.

The reserve funds were established so that the participant payments would increase at a rate of three percent per year over the life of each power purchaser agreement.

Operating Costs are expended for debt service and for operational and maintenance items.

Notes to Financial Statements NOTE A-GENERAL Organization Energy Northwest, a municipal corporation and joint operating agency of the State of Washington, was organized in 1957.

It is empowered to finance, acquire, construct and operate facilities for the generation and transmission of electric power.

On June 30, 2005, its membership consisted of 16 public utility districts and 3 cities, Richland, Seattle and Tacoma. All members own and operate electric systems within the State of Washington.

Energy Northwest is exempt from federal income tax. Energy Northwest has no taxing authority.

Energy Northwest Business Units Each Energy Northwest Business Unit is financed and accounted for separate from all other current or future Business Units.

All electrical energy produced by Energy Northwest net-billed Business Units is ultimately delivered to electrical distribution facilities owned and operated by Bonneville Power Administration (BPA) as part of the Federal Columbia River Power System.

BPA in turn distributes the electricity to electric utility systems throughout the Northwest, including Participants in Energy Northwest's Business Units, for ultimate distribution to consumers. Participants in Energy Northwest's net-billed Business Units consist of publicly owned utilities and rural electric cooperatives located in the western United States who have entered into net-billing agreements with Energy Northwest and BPA for participation in one or more of Energy Northwest's Business Units. BPA is obligated by law to establish rates for electric power which will recover the cost of electric energy acquired from Energy Northwest and other sources as well as BPA's other costs (See Note E).

Energy Northwest operates the Columbia Generating Station, a 1,153 MWe (Design Electric Rating, net) generating plant completed in 1984.

Energy Northwest has obtained all permits and licenses required to operate Columbia, including a Nuclear Regulatory Commission (NRC) operating license that expires in December 2023.

Energy Northwest also operates the Packwood Lake Hydroelectric Project (Packwood), a 27.5 MWe generating plant completed in 1964. Packwood operates under a fifty-year license from the Federal Energy Regulatory Commission (FERC) that expires on February 28, 2010.

The electric power produced by Packwood is sold to 12 utilities, which pay the costs of Packwood, including the debt service on the Packwood Lake Hydroelectric revenue bonds.

The Packwood Participants are obligated to pay annual costs of the Project including debt service, whether or not the Project is

operable, until the outstanding bonds are paid or provisions are made for bond retirement, in accordance with the requirements of the bond resolution. The Participants share Project revenue as well.

Nuclear Project No. 1, a 1,250 MWe plant, was placed in extended construction delay status in 1982, when it was 65 percent complete. Nuclear Project No. 3, a 1,240 MWe plant, was placed in extended construction delay status in 1983, when it was 75 percent complete.

On May 13, 1994, Energy Northwest's Board of Directors adopted resolutions terminating Nuclear Projects Nos. 1 and 3 (see Note F - Nuclear Projects Nos. 1 and 3 Termination).

All funding requirements are net-billed obligations of Nuclear Project No. 1. Energy Northwest wholly owns Nuclear Project No. 1.

Energy Northwest also manages the Business Development Fund and the Nine Canyon Wind Project, and managed the Grays Harbor Energy Facility Project:

26 www.enerav-no rthwest.co m Annual Report

The Business Development Fund was established in April 1997 to pursue and develop new energy-related business opportunities.

The Nine Canyon Wind Project was established in January 2001 for the purpose of exploring and establishing a wind energy project. Phase I of the project was completed in FY 2003. Phase I of the project consists of turbines which are rated at 48 MWe. Phase II of the project was declared operational December 31, 2003. Phase II of the project consists of turbines which are rated at 15.6 MWe. The total project generating capability is approximately 64 MWe.

The Grays Harbor Energy Facility Project was established in July 1990 to collect advances and contributions to pay the costs of investigating new generating projects, including the feasibility of a combustion turbine near Satsop, Washington.

The project purpose was amended during FY 2002 to include the operation and maintenance of a gas fired combustion turbine placed on the Grays Harbor site (owned by Duke Energy Grays Harbor LLC) and included the option to purchase up to 50MW of power generated by the facility. In September 2002, due to market conditions, Duke Energy North America (DENA) placed the project in "Construction Suspension." In February 2004, DENA announced it has no intention to complete the facility with its own funds. All obligations of this business unit have been completed and the fund was dissolved, effective June 30, by the Executive Board in July 2005.

The Internal Service Fund (formerly General Fund) was established in May 1957. It is currently used to account for the central procurement of certain common goods and services for the Business Units on a cost reimbursement basis.

The fund balances (net assets) for Business Development, Nine Canyon Wind Project and the Internal Service Fund includes (in thousands): invested in capital assets, net of related debt, $561, ($24,894) and $14,261, restricted assets of $0, $12,305, $2,722; and unrestricted assets (deficit) of $1,301, $4,344, and

($5,148),

respectively.

NOTE B -

SUMMARY

OF SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting Energy Northwest has adopted accounting policies and principles that are in accordance with Generally Accepted Accounting Principles (GAAP) in the United States of America.

Energy Northwest applies GAAP to the extent it does not conflict with Governmental Accounting Standards Board (GASB) standards (see Note B to the financial statements).

Accounts are maintained in accordance with the uniform system of accounts of the Federal Energy Regulatory Commission (FERC).

Separate funds and books of account are maintained for each Business Unit.

Payment of obligations of one Business Unit with funds of another Business Unit is prohibited, and would constitute violation of bond resolution covenants.

Energy Northwest maintains an Internal Service Fund for centralized control and accounting of certain fixed assets such as data processing equipment, and for payment and accounting of internal services, payroll, benefits, administrative and general expenses, and certain contracted services on a cost reimbursement basis.

Certain assets in the Internal Service Fund are also owned by the Fund and operated for the benefit of other Projects.

Depreciation relating to fixed assets is charged to the appropriate Business Units based upon assets held by each Project.

27 www. ene rav-no rthwest.co m Annual Report

Liabilities of the Internal Service Fund represent accrued payroll, vacation pay, employee benefits, and common accounts payable which have been charged directly or indirectly to Business Units and will be funded by the Business Units when paid. Net amounts owed to or receivable from Energy Northwest Business Units are recorded under Current Liabilities - Due to other Business Units, or Current Assets - Due from other Business Units on the Internal Service Fund Balance Sheet.

The Combined Total column on the financial statements is for presentation only as each Energy Northwest Business Unit is financed and accounted for separately from all other current and future Busiress, Units.

The Fiscal Year (FY) 2005 Combined Total includes eliminations for transactions between Business Units as required in Statement No. 34, Basic Financial Statements and Management's Discussion and Analysis for State and Local Governments" of the Governmental Accounting Standards Board (GASB).

Pursuant to GASB Statement No. 20, "Accounting and Financial Reporting for Proprietary Funds and Other Governmental Entities That Use Proprietary Fund Accounting," Energy Northwest has elected to apply all Financial Accounting Standards Board statements and interpretations, except for those that conflict with or contradict GASB pronouncements.

Specifically, Statement of Governmental Accounting Standard No. 7

'Advance Refundings Resulting in Defeasance of Debr and No. 23 MAccounting and Financial Reporting for Refundings of Debt Reported by Proprietary Activities" conflict with Statement of Financial Accounting Standard (SFAS) No. 140, 'Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." As such, the guidance under Statement of Governmental Accounting Standard No. 7 and No. 23 is followed. Such guidance governs the accounting for bond defeasances and refundings.

The preparation of Energy Northwest financial statements in conformity with GAAP requires management to make estimates and assumptions that directly affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.

Actual results could differ from these estimates. Certain incurred expenses and revenues are allocated to the Business Units based on specific allocation methods and management considers the allocation methods to be reasonable.

Energy Northwest's fiscal year begins on July 1st and ends on June 30t.

Utility Plant Utility plant is stated at original cost.

Plant in service is depreciated by the straight-line method over the estimated useful lives of the various classes of plant, which range from five to 60 years.

During the normal construction phase of a Capital Facility, Energy Northwest's policy is to capitalize all costs relating to the Project, including interest expense, related administrative and general expense, less any interest income earned.

The utility plant and net assets of Nuclear Projects Nos. 1 and 3 have been reduced to their estimated net realizable values due to termination.

A write-down of Nuclear Projects Nos. 1 and 3 was recorded in FY 1995 and was included in Cost in Excess of Billings. Interest expense, termination expenses and asset disposition costs for Nuclear Projects Nos. 1 and 3 have been charged to operations. Utility Plant activity for the year ended June 30, 2005, was as follows:

14,261 Nuclear Fuel All expenditures related to the initial purchase of nuclear fuel for Columbia, including interest, were capitalized and carried at cost. When the fuel is placed in the reactor, the fuel cost is amortized to operating expense on the basis of quantity of heat produced for generation of electric energy. Accumulated nuclear fuel amortization (the amortization of the cost of nuclear fuel assemblies in the reactor used in the production of energy and in the fuel pool for less than six months per FERC guidelines) is $161.1 million as of June 30, 2005 for Columbia.

Energy Northwest has a contract with the Department of Energy (DOE) that requires the DOE to accept title and dispose of spent nuclear fuel. Although the courts have ruled that the DOE had the obligation to accept title to spent nuclear fuel by January 31, 1998, the repository is not expected to be in operation before 2010.

The current period operating expense for Columbia includes a $7.2 million charge from the DOE for future spent nuclear fuel storage and disposal in accordance with the Nuclear Waste Policy Act of 1982.

29 www. e ne rv-no rthwest. co m Annual Report

Energy Northwest has completed a Project to store the spent fuel in commercially available dry storage casks on a concrete pad at the Columbia site. Spent Fuel will be transferred from the Spent Fuel pool to the Independent Spent Fuel Storage Installation (ISFSI) periodically to allow for future refuelings. Current period operating costs include $27.2 million for nuclear fuel and

$1.4 million accrued liability for future dry cask storage costs.

Restricted Assets In accordance with Project bond resolutions, related agreements or state law, separate restricted funds have been established for each Business Unit.

The assets held in these funds are restricted for specific uses including construction, debt service, capital additions, extraordinary operation and maintenance

costs, termination, decommissioning, hazardous waste disposal, and workers' compensation claims.

Long-Term Receivables Long-term receivables include minimum guaranteed amounts adjusted annually pertaining to future discounts for certain goods and services to be provided to Columbia as the result of a litigation settlement and subsequent revisions.

Accounts and Other Receivables Accounts and other receivables for the Internal Service Fund include miscellaneous receivables outstanding from other Business Units that have not yet been collected. The amounts due to each Business Unit are reflected in the due to/from other Business Units account. Accounts and other receivables specific to each Business Unit are recorded in the residing Business Unit.

Asset Retirement Obligation Energy Northwest adopted the Statement of Financial Accounting Standards No. 143, Accounting for Obligations Associated with the Retirement of Long-Lived Asset (SFAS 143) on July 1, 2002. SFAS 143 requires an entity to recognize the fair value of a liability for an asset retirement obligation (ARO), such as nuclear decommissioning and site restoration liabilities, in the period in which it is incurred, rather than using a cost-accumulation approach.

See Note G, Accounting Change for Asset Retirement Obligations.

Decommissioning and Site Restoration Energy Northwest established decommissioning and site restoration funds for Columbia and monies are being deposited each year in accordance with an

.established funding plan.

The NRC has issued rules to provide guidance to licensees of operating nuclear plants on decommissioning the plants at the end of each plant's operating life. In September 1998, the NRC approved and published its

'Final Rule on Financial Assurance Requirements for Decommissioning Power Reactors."

As provided in this rule, each power reactor licensee is required to report to the NRC the status of is decommissioning funding for

-each reactor or share of a reactor it owns. This reporting requirement began on March 31, 1999 and reports are required every two years thereafter. Energy Northwest submitted its most recent report to the NRC in March 2005.

Energy Northwest's current estimate of Columbia's decommissioning costs is $632.1 million (in 2005 dollars). This estimate, which is updated biannually, is based on the NRC minimum amount required to demonstrate reasonable financial assurance for a boiling water reactor with the power level of Columbia.

Site restoration requirements for Columbia are governed by the site certification agreements between 30:

www.enerav-norlhwest.com Annual Report

Energy Northwest and the State of Washington and regulations adopted by the Washington Energy Facility Site Evaluation Council (EFSEC).

Energy Northwest submitted a site restoration plan for Columbia that was approved by the EFSEC on June 12, 1995.

Energy Northwest's current estimate of Columbia's site restoration costs is $79.6 million in constant dollars (based on 2005 Study) and is updated biannually along with the decommissioning estimate.

Both decommissioning and site restoration estimates (based on 2005 Study) are used as the basis for establishing a funding plan that includes escalation and interest earnings until decommissioning activities occur.

Payments to the decommissioning and site restoration funds have been made since January 1985.

The fair value of cash and investment securities in the decommissioning and site restoration funds as of June 30, 2005 totaled approximately $92.0 million and $11.0 million, respectively.

Since September 1996 these amounts have been held and managed by BPA in external trust funds in accordance with NRC requirements and site certification agreements.

Materials and Supplies Materials and supplies are valued at cost, using a weighted-average cost method.

Financing Expense, Bond Discount and Deferred Gain and Losses Financing expenses and bond discounts are amortized over the terms of the respective bond issues using the bonds outstanding method.

In accordance with the Statement of Governmental Accounting Standard No. 23, losses on debt refundings have been deferred and amortized as a component of interest expense over the shorter of the remaining life of the old or new debt. The balance sheet includes the original deferred amount less recognized amortization expense and is included as a reduction to the new debt.

Current Maturities of Revenue Bonds Current maturities (less than one year) of revenue bonds payable from restricted assets are reflected as current maturities.

Debt that matures greater than one year is reflected as Long-Term Debt.

Accounts Payable and Accrued Expenses Liabilities-Payable From Restricted Assets-Columbia includes $96.9 million for decommissioning and site restoration.

Nuclear Project No. 1 includes

$13.3 million for decommissioning and site restoration.

The Nine Canyon Wind Project includes $0.5 million for decommissioning and site restoration.

Current Liabilities-Internal Service Fund accounts payable and accrued expenses include $4.0 million for payroll and related benefits, $17.2 million for compensated absences, and $2.4 million for outstanding warrants.

Other Non-Current Uabilities-lncludes deferrals to cask liability and uranium enrichment assessment Cask liability relates to the storage and disposal of spent fuel.

Uranium enrichment assessment is related to fuel and is scheduled to be completed in two years.

Fair Value of Financial Instruments The fair value of financial instruments has been estimated using available market information and certain assumptions.

Considerable judgment is required in interpreting market data to develop fair value estimates and such estimates are not necessarily indicative of the amounts that could be realized in a current market exchange. The following methods and assumptions were used to estimate the fair value of each of the following financial instruments.

Financial instruments for which the carrying value is considered a reasonable approximation of fair value include: cash, accounts and other receivables, accounts 31 www. enerav-no rthwest. co m Annual Report

payable and accrued expenses, advances from Members and others, other non-current liabilities and due to/from Participants, funds, and other Business Units. The fair values of investments (see Note C) and revenue bonds payable (see Outstanding Long-Term Debt Schedule) have been estimated based on quoted market prices for such instruments or based on the fair value of financial instruments of a similar nature and degree of risk.

Revenues Energy Northwest accounts for expenses on an accrual basis, and recovers, through various agreements, actual cash requirements for operations and debt service for Columbia, Packwood, Nuclear Project No. 1 and Nuclear Project No. 3. For these Business Units, Energy Northwest recognizes revenues equal to expenses for each period. No net revenue or loss is recognized, and no equity is accumulated.

The difference between cumulative billings received and cumulative expenses is recorded as either billings in excess of costs (liability) or as costs in excess of billings (asset), as appropriate.

Such amounts will be settled during future operating periods.

Energy Northwest accounts for revenues and expenses on an accrual basis for the remaining Business Units. The difference between cumulative revenues and cumulative expenses is recognized as net revenue or losses and included in fund equity for each period.

Energy Northwest has accrued as income (contribution) from the

DOE, Renewable Energy Performance Incentive (REPI) payments that enable the Nine Canyon Wind Project to receive funds based on generation as it applies to the REPI bill. The REPI was created as part of the Energy Policy Act of 1992 to promote increases in the generation and utilization of electricity from renewable energy sources and to further the advances of renewable energy technologies.

This program, authorized under section 1212 of the Energy Policy Act of 1992, provides financial incentive payments for electricity produced and sold by new qualifying renewable energy generation facilities. For the first time in the history of the program, congressional funding for qualified wind programs was not fully funded. The Nine Canyon Wind Project recorded a receivable for sixty-eight (68%) of the applied REPI funding in the amount of $2.3 million for FY 2005, representing its share of funded amounts. The payment stream and the REPI receipts were projected to cover the total costs over the purchase agreement. Permanent shortfalls in REPI funding will lead to future increases in the billing of the Project participants in order to cover total Project costs.

Concentration of Credit Risk Financial instruments which potentially subject Energy Northwest to concentrations of credit risk consist of available-for-sale investments, accounts receivable, other receivables, long-term receivables and costs in excess of billings.

Energy Northwest invests exclusively in U.S.

Government securities and agencies. Energy Northwest's accounts receivable and costs in excess of billings are concentrated with Project Participants. and SBPA through the net billing agreements. See Note E, Long-Term Debt, Security-Nuclear Projects Nos. 1, 3, Columbia and Packwood Lake Hydroelectric Project.

The long-term receivable.,is-with a large anc.. stable company which Energy Northwest considers to be of low credit. risk. Other large receivables are secured through the use of letters of credit and other similar security mechanisms or are with large and stable companies which Energy Northwest considers to be of low credit risk. As a consequence, Energy Northwest considers the exposure of the Business Units to concentration of credit risk to be limited.

NOTE D - RETIREMENT BENEFITS Substantially all Energy Northwest full-time and qualifying part-time employees participate in one of the following statewide retirement systems administered by the Washington State Department of Retirement Systems, under cost-sharing multiple-employer public employee defined benefit and defined contribution retirement plans.

The Department of Retirement Systems (DRS), a department within the primary government of the State of Washington, issues a publicly available comprehensive annual financial report (CAFR) that includes financial statements and required supplementary information for each plan. The DRS CAFR may be obtained by writing to: Department of Retirements Systems, Administrative Services Division, P.O. Box 48380, Olympia, WA 98504-8380.

The following disclosures are made pursuant to GASB Statement No. 27, "Accounting for Pensions by State and Local Government Employers."

Public Employee's Retirement System (PERS) Plans 1, 2, and 3 Plan DesciIption PERS is a

cost-sharing, multiple-employer defined benefit pension plan.

Membership in the plan includes: elected officials; state employees; employees of the Supreme, Appeals, and Superior courts (other than judges in a judicial retirement system); employees of legislative committees; college and university employees not in national higher education retirement programs; judges of district and municipal courts; non-certificated employees of school districts; and employees of local government, including Energy Northwest.

The PERS system includes three plans. Participants who joined the system by September 30, 1977 are Plan 1 members.

Those joining thereafter are enrolled in Plan 2, unless they exercise an option to transfer their membership to Plan 3.

the option of choosing membership in either PERS Plan 2 or PERS Plan 3. The option must be exercised within 90 days of employment. Retirement benefits are financed from employee and employer contributions and investment earnings.

Retirement benefits in Plan 1 and Plan 2 are vested after completion of five years of eligible service.

PERS Plan 3 participants are vested immediately.

Funding Policy Each biennium, the state Pension Funding Council adopts Plan 1 employer contribution rates, Plan 2 employer and employee rates, and Plan 3 employer contribution rates.

Employee contribution rates for Plan 1 are established by statute at six percent and do not vary from year to year.

The employer and employee contribution rates for Plan 2 and employer rate for Plan 3 are set by the director of the Department of Retirement Systems based on recommendations by the Office of the State Actuary to continue to fully fund the plan. All employers are required to contribute at the level established by state law. The methods used to determine the contribution requirements are established under state statute in accordance with chapters 41.40 and 41.45 Revised Code of Washington.

The required contribution rates for the defined benefit plan expressed as a percentage of current year covered payroll, as of June 30, 2005 were:

PERS PERS PERS Plan 1 Plan 2 Plan 3 Employer*

1.40%

1.40%

1.40%**

Employee 6.00%

1.18%

• The employer rates include the employer administrative expense fee currently set at 0.19%. This rate reflects the change effective September 1, 2004.

Previous to this period the rate was 0.22%.

• • Plan 3 defined benefits portion only.

• • • Variable from 5.0% minimum to 15.0%

maximum based on rate selected by PERS 3 member.

Both Energy Northwest and the employees made the required contributions. Energy Northwest's required contributions for the years ended June 30 was:

$ 95,821 who retired after January 1, 1995 is $2.33 per $1,000 of coverage with a maximum limit of $10,000. Employees who retired prior to January 1, 1995 contribute $.58 per

$1,000 of coverage while Energy Northwest pays the remainder. Premiums are paid to the insurer on a current period basis.

At the time each employee retires, Energy Northwest accrues a liability for the actuarial value of estimated future premiums, net of retiree contributions.

The total liability recorded at June 30, 2005 was $0.9 million for these benefits.

During FY 2005, pension costs for Energy Northwest employees and post-employment life insurance benefit costs for retirees were calculated and allocated to each Business Unit based on direct labor dollars.

Approximately 93 percent of all such costs were allocated to Columbia during FY 2005.

401(k) and 457 Plan Deferred Compensation Plan Energy Northwest provides a 401(k) Deferred Compensation Plan (the 401(k) Plan), and a 457 Deferred Compensation Plan. Both Plans are defined contribution plans that were established to provide a means for investing savings by employees for retirement purposes.

All permanent, full time employees are eligible to enroll in the Plans. Each participant may elect to contribute pre-tax annual compensation, subject to current Internal Revenue Service limitations. For the 401(k) Plan, Energy Northwest matches 50% of the portion of the participants salary deferral amount, which does not exceed 5% of the participant's 401(k) eligible earnings for the 401(k) Plan year.

Participants direct the investment of their contributions. Participants are immediately vested in their contributions plus actual earnings thereon.

During FY 2005 Energy Northwest contributed $2.1 million in employer matching funds.

In addition to the pension benefits available through PERS, Energy Northwest offers post-employment life insurance benefits to retirees who are eligibli to receive pensions under PERS Plan 1, Plan 2, and Plan 3.

Ninety-seven retirees have elected to participate in this insurance. In 1994, Energy Northwest's Executive Board approved provisions which continued the life insurance benefit to retirees at 25 percent of the premium for employees who retire prior to January 1, 1995 and charged the full 100 percent premium to employees who refired after December 31, 1994.

The life insurance benefit is equal to the employee's annual rate of salary at retirement for non-bargaining employees retiring prior to January 1, 1995.

NOTE E - LONG-TERM DEBT Each Energy Northwest Business Unit is financed separately.

The resolutions of Energy Northwest authorizing issuance of revenue bonds for each Business Unit provide that such bonds are payable from the revenues of that Business Unit. All bonds issued under Resolutions Nos. 769, 775 and 640 for Nuclear Projects Nos. 1, 3 and Columbia, respectively, have the same priority of payment within the Business Unit (the "Prior Lien Bonds"). All bonds issued under Resolutions Nos.

835, 838 and 1042 (the 'Electric Revenue Bonds") for Nuclear Projects Nos. 1, 3 and Columbia, respectively, are subordinate to the Prior Lien Bonds and have the same subordinated priority of payment within the Business Unit.

During the year ended June 30, 2005, Energy Northwest issued, for Nuclear Projects 1, 3, and Columbia, the Series 2005-A Bonds, Series 2005-B, Bonds and Series 2005-C Bonds. The Series 2005-A, 2005-B, and 2005-C Bonds, issued for Nuclear Project No. 1, Nuclear Project No. 3, and Columbia are fixed rate bonds with a weighted average coupon interest rate of 5.00%.

The Series 2005-A Bond Proceeds of $346.6 million refunded

$346.8

million, par amount,, of outstanding bonds having a weighted average coupon interest rate of 5.88%. The $346.6 million of proceeds associated with the Series 2005-A Bonds were allocated to Nuclear Project No. 1 ($79.4 million), Columbia ($125.2 million), and Nuclear Project No. 3 ($142.0 million). This.

transaction resulted in a net loss for accounting purposes of $1.4 million for Nuclear Project 1, a net loss of

$1.0 million for Nuclear Project 3, and a net gain of

$.2 million for Columbia. According to GASB Statement No. 7, "Advance Refundings Resulting in Defeasance of Debt", the amortization of the gains and losses on the refundings are calculated based on the shorter of the life of the new debt compared to the old debt.

The Series 2005-A bonds resulted in the recognition of a net accounting loss of $2.2 million for the year ended June 30, 2005. Energy Northwest increased its aggregate debt service by $121.0 million over the next 13 years due to extending the date of maturities; however an economic gain of $4.2 million was obtained.

The Series 2005-B Bonds, issued for Nuclear Project No.1, Nuclear Project No. 3 and Columbia, in the aggregate amount of $3.6 million, are taxable fixed-rate bonds with a weighted average coupon interest rate of 4.11%.

The 2005-B Bond Proceeds were used for the purpose of paying costs relating to the issuance of the Series 2005-A and Series 2005-B Bonds as well as certain costs relating to the refunding of certain outstanding bonds.

Lastly, some of the Series 2005-B Bond Proceeds will be used to finance a portion of the cost of certain capital improvements.

The Series 2005-C Bonds, issued for Columbia, in the amount of $91.9 million, are fixed-rate bonds with an average coupon interest rate of 4.60%. The Series 2005-C Bonds were issued to finance a portion of the cost of certain capital improvements at Columbia and to pay costs relating to nuclear fuel purchases.

During the year ended June 30, 2005, Energy Northwest issued, for Nine Canyon Wind Project, the Series 2005 Bonds. The Series 2005 Bonds, issued for Nine.Canyon Wind Project are fixed-rate bonds with a weighted-average coupon interest rate of 4.77%.

The Series-2005 Bond Proceeds of $65.6 million refunded

$59.4 million of outstanding bonds having a weighted average coupon interest rate of 5.77%. This transaction resulted in a net loss for accounting purposes of $7.2 million for Nine Canyon Wind Project. According to GASB Statement No. 7, "Advance Refundings Resulting in Defeasance, of,Debt", the amortization of the gains and losses on the refundings are calculated based, on the shorter of the life of the new debt compared to the old debt.

.Annual Report

The Series 2005 Bonds resulted in the recognition of an accounting loss of $7.2 million for the year ended June 30, 2005. Energy Northwest decreased its aggregate debt service payments by $3.7 million over the next 19 years and obtained an economic gain of $2.8 million.

In prior fiscal years, Energy Northwest also defeased certain revenue bonds by placing the net proceeds from the refunding bonds in irrevocable trusts to provide for all required future debt service payments on the refunded bonds until their dates of redemption.

Accordingly, the trust account assets and liability for the defeased bonds are not included in the financial statements in accordance with GASB statements No. 7 and 23.

Including the FY 2005 defeasements, $260.5 million, $151.5 million, $304.1 million, and $59.4 million of defeased bonds were not called or had not matured at June 30, 2005, for Nuclear Projects Nos. 1 and 3, Columbia, and Nine Canyon Wind Project respectively.

Outstanding revenue bonds for the various Business Units as of June 30, 2005, and future debt service requirements for these bonds are presented as supplementary information at the end of the Financial Section of this report.

Security - Nuclear Projects Nos. 1 and 3 and Columbia Project Participants have purchased all of the capability of Nuclear Projects Nos. 1 and 3 and Columbia.

BPA has in turn acquired the entire capability from the Participants under contracts referred to as net-billing agreements. Under the net-billing agreements for each of the Business Units, Participants are obligated to pay Energy Northwest a pro rata share of the total annual costs of the respective Projects, including debt service on bonds relating to each Business Unit. BPA is then obligated to reduce amounts from Participants under BPA power sales agreements by the same amount.

The net-billing agreements provide that Participants and BPA are obligated to make such payments whether or not the Projects are completed, operable or operating and notwithstanding the suspension, interruption, interference, reduction or curtailment of the Projects' output.

On May 13, 1994, Energy Northwest's Board of Directors adopted resolutions terminating Nuclear Projects Nos. 1 and 3. The Nuclear Projects Nos. 1 and 3 Project agreements and the net-billing agreements, except for certain sections which relate only to billing processes and accrued liabilities and obligations under the net-billing agreements, ended upon termination of the Projects.

Energy Northwest entered into an agreement with BPA to provide for continuation of the present budget approval, billing and payment processes. With respect to Nuclear Project No. 3, the ownership agreement among Energy Northwest and private companies was terminated in FY 1999.

The ownership of all real and personal property interests was transferred to Energy Northwest.

Security - Packwood Lake Hydroelectric Project Energy Northwest, Benton County PUD and Franklin County PUD have signed Power Sales agreements which became effective November 4, 2002 and ran through October 30, 2004. A one-year extension was negotiated for the period beginning November 1, 2004 and extending through October 30, 2005. A new contract effective October 1, 2005 and extending through September 30, 2008 has been signed.

Benton and Franklin County PUD's agree to pay Energy Northwest in exchange for the total output of electric capacity and energy delivered from the Packwood Generation Project.

The Packwood Participants are obligated to pay annual costs of the Project including debt service, whether or not the Project is operable, until the outstanding bonds are paid or provisions are made for bond retirement, in accordance with the requirements of the bond resolution.

The Participants also share project revenue to the extent that the amounts exceed project costs.

NOTE F - COMMITMENTS AND CONTINGENCIES Nuclear Project No. 1 Termination Since the Nuclear Project No.1 termination, Energy Northwest has been planning for the demolition of Nuclear Project No. 1 and restoration of the site, recognizing the fact that there is no market for the sale of the Project in its entirety and to-date, no viable alternative use has been found. The final level of demolition and restoration will be in accordance with agreements discussed later in Note F under "Nuclear Projects Nos. 1 and 4 Site Restoration."

Nuclear Project No. 3 Termination In June 1994, the Nuclear Project No. 3 Owners Committee voted unanimously to terminate the Project.

During 1995, a group from Grays Harbor County, Washington, formed the Satsop Redevelopment Project (SRP). The Satsop Redevelopment Project introduced legislation with the State of Washington under Senate Bill No. 6427, which passed and was signed by the Governor of the State of Washington on March 7, 1996.

The legislation enables local governments and Energy Northwest to negotiate an arrangement allowing such local governments to assume an interest in the site on which Nuclear Project No. 3 and Nuclear Project No. 5 exist for economic development by transferring ownership of all or a portion of the site to local government entities.

This legislation also provides for the local government entities to assume regulatory responsibilities for site restoration requirements and control of water rights. In February 1999, Energy Northwest entered into a transfer agreement with the Satsop Redevelopment Project (SRP) to transfer the real and personal property at the site of Nuclear Project No. 3 and Nuclear Project No. 5. The SRP also agreed to assume regulatory responsibility for site restoration. Therefore, Energy Northwest is no longer responsible to the State of Washington and EFSEC for any site restoration costs.

Nuclear Projects Nos. 1 and 4 Site Restoration Site restoration requirements for Nuclear Projects Nos. 1 and 4 are governed by site certification agreements between Energy Northwest and the State of Washington and regulations adopted by

EFSEC, and a lease agreement with the DOE. Energy Northwest submitted a site restoration plan for Nuclear Projects Nos. 1 and 4 to EFSEC on March 8, 1995, which complied with EFSEC requirements to remove the assets and restore the sites by demolition, burial, entombment, or other techniques such that the sites pose minimal hazard to the public. EFSEC approved Energy Northwest's site restoration plan on June 12, 1995. In its approval, EFSEC recognized that there is uncertainty associated with Energy Northwest's proposed plan. Accordingly, EFSEC's conditional approval provides for additional reviews once the details of the plan are finalized. A new plan with additional details was submitted in FY 2003. This submittal was used to calculate the ARO discussed in Note G of the financial statements.

Business Development Fund Interest in Northfwest Open Access Network The Business Development Fund is a member of the Northwest Open Access Network

("NoaNer).

Members formed NoaNet pursuant to an Interlocal Cooperation Agreement for the development and efficient use of a communication network in conjunction with BPA for use by the Members and others.

The Business Development Fund has a 7.38%

interest in NoaNet with an additional 25 percent step-up possible for a maximum 9.23 percent.

'As of June30, 2005, NoaNet has $24.6 million in outstanding bonds. The members are obligated to pay the principal and interest on the bonds when due in the event and to the extent that 40 www.eneray-northwest.com Annual Report

NoaNet's Gross Revenue (after payment of costs of Maintenance and Operation) is insufficient for this purpose.

The maximum principal share (with step-up) that the Business Development Fund could be required to pay is $2.3 million. It is important to note that the Business Development Fund is not obligated to reimburse losses of NoaNet unless an assessment is made to NoaNet's members based on a two-thirds vote of the membership.

In FY 2005 the Business Development Fund contributed

$136K to NoaNet based on an assessment by the NoaNet members. This equity contribution was reduced to zero at year-end because NoaNet had a negative net equity position of $15.3 million.

Future equity contributions, if any, will be treated the same until NoaNet has a positive equity position.

Business Development Fund Enriched Uranium Lease In January 2004, the Business Development Fund entered into an enriched uranium lease agreement with two third parties whereby one third party leases enriched uranium to the Business Development Fund and concurrently allows the Business Development Fund to lease the enriched uranium to the other third party. The Business Development Fund earns a net margin of 0.625% per annum (through June 30, 2006) on the market value of the leased enriched uranium. The lease revenues and expenses are presented on a net basis in the Statements of Operations as the Business Development Fund does not take title to the enriched uranium, does not have inventory risk and is only at risk for the net margin.

For FY 2005 the Business Development Fund recorded net revenues of $0.1 million in operating revenues under this agreement.

Other Litigation and Commitments Energy Northwest is involved in various claims, legal actions and contractual commitments and in certain claims and contracts arising in the normal course of business. Although some suits, claims and commitments are significant in amount, final disposition is not determinable. In the opinion of management, the outcome of such litigation, claims or commitments will not have a material adverse effect on the financial positions of the Business Units or Energy Northwest as a whole.

The future annual cost of the Business Units, however, may either be increased or decreased as a result of the outcome of these matters.

Nuclear Licensing and Insurance Energy Northwest is a licensee of the Nuclear Regulatory Commission and is subject to routine licensing and user fees, to retrospective premiums for nuclear liability insurance, and to license modification, suspension, or revocation or civil penalties in the event of violations of various regulatory and license requirements.

The Price Anderson Act currently provides for nuclear liability insurance of over $10.7 billion per incident, which is covered by a combination of commercial nuclear insurance and mandatory industry self-insurance. Energy Northwest has purchased the maximum commercial insurance available of $300 million, which is the first layer of protection. The second layer of protection is provided through a mandatory industry self-insurance plan wherein each licensed nuclear facility required to participate in the plan (currently 104 participants) may be assessed up to

$100.6 million per incident, subject to a maximum annual assessment of $10 million per year.

Nuclear property damage and decontamination liability insurance requirements are met through a combination of commercial nuclear insurance policies purchased by Energy Northwest and BPA.

The total amount of insurance purchased is currently $2.75 billion.

The deductible for this coverage is $5.0 million per occurrence.

NOTE G - ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS Energy Northwest adopted SFAS 143 on July 1, 2002 (see Note B, Summary of Significant Accounting Policies). This Statement requires an entity to recognize the fair value of a liability for an ARO, measured at estimated fair value, for legal obligations related to the dismantlement and restoration costs associated with the retirement of tangible long-lived assets, such as nuclear decommissioning and site restoration liabilities, in the period in which it is Incurred.' Upon initial recognition of-the AROs that are measurable, the probability weighted future cash flows for the associated retirement costs, discounted using a credit-adjusted-risk-free rate, are recognized as both a liability and as an increase in the capitalized carrying amount of the related long-lived assets. Capitalized asset retirement costs are depreciated over the life of the related asset with accretion of the ARO liability classified as an operating expense on the statement of operations and fund equity each period.

Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss if the actual costs differ from the recorded amount.

However, with regard to the net billed Projects, BPA is obligated to provide for the entire cost of decommissioning and site restoration, therefore, any gain or loss recognized upon settlement of the ARO results in' an adjustment to either the billings in excess of costs (liability) or costs in excess of billings (asset), as appropriate, as no net revenue or loss is recognized, and no equity is accumulated for the net billed projects.

Energy Northwest has identified legal obligations to retire generating -plant assets at the following business units: Columbia Generating Station, Nuclear Project No. 1 and Nine Canyon Wind Project. Decommissioning and" site restoration requirements for Columbia and Nuclear Project No. 1 are governed by the NRC regulations and site certification agreements between Energy Northwest and the State of Washington and regulations adopted by the EFSEC and a lease agreement with the DOE (see Notes B and F). Prior obligations recorded with regard to the decommissioning obligation of Columbia and Nuclear Project No. 1 were reversed as of the adoption date, with revised obligations being recorded in accordance with SFAS No. 143. As a result of the net billing arrangement, the adoption of SFAS No. 143 for Columbia Generating Station and Nuclear Project No. 1 did not result in a cumulative effect adjustment on the statement of operations and fund equity, but resulted in a charge to costs in excess of billings.

Energy Northwest applied SFAS 143 to the ISFSI project, which is part of CGS, beginning in FY 2005 resulting in decommissioning and accretion expenses of
