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.

Reduce Waste Through the pollution prevention program, Energy Northwest has set aggressive targets to reduce all types of waste including hazardous and mixed waste. The pollution prevention program prioritizes minimizing waste through job planning and product substitution with more environmentally friendly chem icals. When waste must be generated, disposal is only used if reuse and recycle options are unavailable.

Recycling is important in reducing waste and all facilities participate in the recycling program. During fiscal 2016, the agency recycled more than 209 tons of waste (plastic, aluminum, paper, cardboard and metal).

NINE CANYON WIND PROJECT significantly lower operating costs (insurance, labor and major maintenance).

The Nine Canyon Wind Project (Nine Canyon) is wholly owned and operated Operating expenses decreased from $13.3 million in FY 2015 to $12.7 million in by Energy Northwest. Nine Canyon is located in the Horse Heaven Hills area FY 2016. These cost control measures along with the $0.9 million in decreased southwest of Kennewick, Washington. Electricity generated by Nine Canyon is treasury related expenses in FY 2016 (a result of the 2015 refinancing) helped purchased by t'aof1c Northwest Public Utility Districts (purchasers) .

The total Nine Canyon generating estimates, decreases to deferred inflows of $0.3 million for pensions and $0.1 capability is 95.9 MW, enough energy for approximately 39,000 average homes. million for unamortized gain on bond refunding. The change in net position of Nine Canyon produced 244.62 GWh of electricity in FY 2016 versus 196. 75 $3.5 million from operations in FY 2016 as compared to an increase of $1.9 GWh in FY 2015. The increase of 24.3 percent was a result of the third highest million in FY 2015 reflects the steady operations and treasury savings due to year on record for generation in FY 2016 as compared to the ninth highest for the 2015 refinancing.

Nine Canyon's cost performance is measured by the cost of power indicator. payments that enable Nine Canyon to receive funds based on generation as The cost of power for FY 2016 was $6.07 cents per kWh as compared to it applies to the REPI legislation. REPI was created to promote increases in

The cost of power fluctuates year to year the generation and utilization of electricity from renewable energy sources depending on various factors such as wind totals and unplanned maintenance and to further the advances of renewable energy technologies. This program, and is distinctly different than revenue billed cost of power discussed below in authorized under Section 1212 of the Energy Policy Act of 1992, provides revenue and expense analysis. The decrease of 27.0 percent in cost of power for financial incentive payments for electricity produced and sold by new qualifying FY 2016 was directly attributable to more favorable wind conditions along with renewable energy generation facilities.

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 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. The results from FY 2016 reflect the revised rate plan scenario and gradual increase in the return of total net position 30 2016 Energy Northwest Annual Report

INTERNAL SERVICE FUND The Internal Service Fund (ISF) (formerly the General Fund) was established The net increase in net position and liabilities is due to increases in accounts in May 1957.
