A MESSAGE TO OUR STAKEHOLDERS We're proud to report Energy Northwest's 1,100 employee-led workforce produced a near-record output of electricity for the ratepayers of the Pacific Northwest during fiscal year 2016.
Columbia Generating Station sent 9,617,206 megawatt-hours ofnet generation to the grid, its second-highest fiscal year generation total ever. Columbia also set monthly generation records in December and January; and achieved its lowest dose in a fiscal year in more than 30 years of operation, a direct result of the efforts of employees working as a team.                                                MARK REDDEMANN Packwood Lake Hydroelectric Project and Nine Canyon Wind Project                              SID MORRISON availability remained above generation goals for the fiscal year. Nine Canyon set a record availability for the fiscal year at 99.32 percent. The wind turbines also set availability records for August, October, February, March, April and June.
Based on generation achievements, EN paid more than $4.4 million in privilege taxes to the state of Washington. Those funds help educate our children and sustain our standard of living in the Pacific Northwest.
Columbia launched Delivering the Nuclear Promise, an initiative driven by chief nuclear officers throughout the industry aimed at maintaining operational focus while significantly increasing plant efficiency - and value - by 2020. Our agency-specific cost-effective operation plan aligns well with the nuclear promise goal to reduce the cost of power from U.S. plants during the next three to five years.
This fall, the Energy Northwest executive board approved corrective actions developed by agency leaders in response to a recent investigation into claims raised in anonymous letters to the board. Many of the actions have already been implemented. The independent investigation team concluded senior leadership has been transparent and Columbia is operated in a safe manner. The investigation also found that employees are nearly unanimous in stating their willingness to raise concerns to their direct supervisors, managers and senior leadership; are willing to raise concerns through the employee concerns and corrective action programs; and have positive assessments of their work en:vironment.
This year we added "Successful Outage" to Phase IV, Sustaining Excellence, of our Excellence in Performance program that we implemented at Energy Northwest more than five years ago. The team planning next May's refueling and maintenance outage has and continues to prepare to execute the work planned during the 40-day schedule to ensure we are predictable, and return Columbia on line within the allotted time frame.
Despite challenges affecting the entire power industry, it's been a productive, record-setting year at Energy Northwest. All of us at Energy Northwest look forward to next year when we celebrate 60 years of providing the region with safe, reliable, cost-effective, responsible power generation and energy solutions.

INDEPENDENT AUDITOR'S REPORT To the Executive Board of Energy Northwest:
Report on the Financial Statements We have audited the accompanying financial statements of Energy Northwest. as of and for the year ended June 30, 2016, and the related notes to the financial statements, which collectively comprise the Energy Northwest's basic financial statements as listed in the table of contents.
Management's Responsibility for the Financial Statements Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.
Auditors' Responsibility Our responsibility is to express opinions on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America . Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error.
In making those risk assessments, the auditor considers internal control relevant to the Energy Northwest's preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Energy Northwest's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinions.
Opinions In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Energy Northwest as of June 30, 2016, and the respective changes in financial position and cash flows thereof for the years then ended in accordance with accounting principles generally accepted in the United States of America.
Other Matter Required Supplementary Information:
Accounting principles generally accepted in the United States of America require that the required supplementary information as listed in the table of contents be presented to supplement the basic financial statements. Such information, although not a part of the basic financial statements, is required by the Governmental Accounting Standards Board who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with auditing standards generally accepted in the United States of America, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management's responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance.
Other Information Our audit was conducted for the purpose of forming opinions on the basic financial statements as a whole. The other information as identified in the table of contents is presented for purposes of additional analysis and is not a required part of the basic financial statements. Such information has not been subjected to the auditing procedures applied in the audit of the basic financial statements, and accordingly, we express no opinion or provide any assurance on it.

The billing rates for the Nine Canyon participants    FY 2016 J                                29.87 increased 69 percent and 80 percent for Phase I and Phase II participants respectively in FY 2008 in order to cover total project costs, projected out to    FY 2015 :

Revenues and Expenses Analysis                                                      to $92.87 per MWh for FY 2015. Billings for FY 2015 were at the same levels Operating revenues remained relatively steady from FY 2015 levels,            of FYI 6 but the average rate was impacted by less favorable generation in FY increasing $52 thousand. The project received $18.27 million from the billing of  2015. BPA scheduling charges remained relatively steady for both years at the purchasers at an average rate of $74. 70 per MWh for FY 2016 as compared        $1.06 million. The stabilization of revenue is reflective of the implementation of the revised rate plan in FY 2014/2015 to account for costs of operations over the remaining life of the project, taking into account the REPI shortfalls in the early years of the project. Operating costs decreased $0.6 million in FY NINE CANYON WIND PROJECT Total Operating Costs (dollars in thousands)            2016 from $13.3 million in FY 2015 to $12. 7 million in FY 2016. Decreased operating costs in FY 2016 were due to lower turbine maintenance and major component rebuild/gear boxes of $0. 7 million offset by slightly higher labor and FY 2016                                                                    15.881  administrative non labor costs of $0.1 million.
Other income and expenses decreased $0.9 million from $4.1 million in net FY2015                                                                    17.383  expenses FY 2015 to $3.2 million in FY 2016. Decreased interest costs of $0.8 million, decreases in amortized bond expenses of $0.4 million and increased interest revenue of $0.1 million accounted for the change. Net income or FY 2014                                                                    18.750 change in net position of $3.5 million for FY 2016 was a direct result of the planned rate structure with projected treasury savings due to refunding and FY 2013                                                                    18.805 lower than budgeted operating costs.
The original plan anticipated operating at a loss in the early years and FY 2012                                                                    17.467 gradually increasing the rate charged to the purchasers to avoid a large rate 12,000    15,000 increase after the REPI expires.

The rate plan in FY 2008 was revised to account for the shortfall experienced in the REPI funding and to provide a new rate scenario out to the 2030 project end date. Energy Northwest did not receive REPI funding in FY 2016 and is not anticipating receiving any future REPI incentives.

A MESSAGE TO OUR STAKEHOLDERS We're proud to report Energy Northwest's 1,100 employee-led workforce produced a near-record output of electricity for the ratepayers of the Pacific Northwest during fiscal year 2016.

Columbia Generating Station sent 9,617,206 megawatt-hours ofnet generation to the grid, its second-highest fiscal year generation total ever. Columbia also set monthly generation records in December and January; and achieved its lowest dose in a fiscal year in more than 30 years of operation, a direct result of the efforts of employees working as a team. MARK REDDEMANN Packwood Lake Hydroelectric Project and Nine Canyon Wind Project SID MORRISON availability remained above generation goals for the fiscal year. Nine Canyon set a record availability for the fiscal year at 99.32 percent. The wind turbines also set availability records for August, October, February, March, April and June.

Based on generation achievements, EN paid more than $4.4 million in privilege taxes to the state of Washington. Those funds help educate our children and sustain our standard of living in the Pacific Northwest.

Columbia launched Delivering the Nuclear Promise, an initiative driven by chief nuclear officers throughout the industry aimed at maintaining operational focus while significantly increasing plant efficiency - and value - by 2020. Our agency-specific cost-effective operation plan aligns well with the nuclear promise goal to reduce the cost of power from U.S. plants during the next three to five years.

This fall, the Energy Northwest executive board approved corrective actions developed by agency leaders in response to a recent investigation into claims raised in anonymous letters to the board. Many of the actions have already been implemented. The independent investigation team concluded senior leadership has been transparent and Columbia is operated in a safe manner. The investigation also found that employees are nearly unanimous in stating their willingness to raise concerns to their direct supervisors, managers and senior leadership; are willing to raise concerns through the employee concerns and corrective action programs; and have positive assessments of their work en:vironment.

This year we added "Successful Outage" to Phase IV, Sustaining Excellence, of our Excellence in Performance program that we implemented at Energy Northwest more than five years ago. The team planning next May's refueling and maintenance outage has and continues to prepare to execute the work planned during the 40-day schedule to ensure we are predictable, and return Columbia on line within the allotted time frame.

Despite challenges affecting the entire power industry, it's been a productive, record-setting year at Energy Northwest. All of us at Energy Northwest look forward to next year when we celebrate 60 years of providing the region with safe, reliable, cost-effective, responsible power generation and energy solutions.

INDEPENDENT AUDITOR'S REPORT To the Executive Board of Energy Northwest:

Report on the Financial Statements We have audited the accompanying financial statements of Energy Northwest. as of and for the year ended June 30, 2016, and the related notes to the financial statements, which collectively comprise the Energy Northwest's basic financial statements as listed in the table of contents.

Management's Responsibility for the Financial Statements Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditors' Responsibility Our responsibility is to express opinions on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America . Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error.

In making those risk assessments, the auditor considers internal control relevant to the Energy Northwest's preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Energy Northwest's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinions.

Opinions In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Energy Northwest as of June 30, 2016, and the respective changes in financial position and cash flows thereof for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Other Matter Required Supplementary Information:

Accounting principles generally accepted in the United States of America require that the required supplementary information as listed in the table of contents be presented to supplement the basic financial statements. Such information, although not a part of the basic financial statements, is required by the Governmental Accounting Standards Board who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with auditing standards generally accepted in the United States of America, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management's responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance.

Other Information Our audit was conducted for the purpose of forming opinions on the basic financial statements as a whole. The other information as identified in the table of contents is presented for purposes of additional analysis and is not a required part of the basic financial statements. Such information has not been subjected to the auditing procedures applied in the audit of the basic financial statements, and accordingly, we express no opinion or provide any assurance on it.

BPA scheduling charges remained relatively steady for both years at the purchasers at an average rate of $74. 70 per MWh for FY 2016 as compared $1.06 million. The stabilization of revenue is reflective of the implementation of the revised rate plan in FY 2014/2015 to account for costs of operations over the remaining life of the project, taking into account the REPI shortfalls in the early years of the project. Operating costs decreased $0.6 million in FY NINE CANYON WIND PROJECT Total Operating Costs (dollars in thousands) 2016 from $13.3 million in FY 2015 to $12. 7 million in FY 2016. Decreased operating costs in FY 2016 were due to lower turbine maintenance and major component rebuild/gear boxes of $0. 7 million offset by slightly higher labor and FY 2016 15.881 administrative non labor costs of $0.1 million.

Other income and expenses decreased $0.9 million from $4.1 million in net FY2015 17.383 expenses FY 2015 to $3.2 million in FY 2016. Decreased interest costs of $0.8 million, decreases in amortized bond expenses of $0.4 million and increased interest revenue of $0.1 million accounted for the change. Net income or FY 2014 18.750 change in net position of $3.5 million for FY 2016 was a direct result of the planned rate structure with projected treasury savings due to refunding and FY 2013 18.805 lower than budgeted operating costs.
