Portland General Electric reports 2015 financial results and initiates 2016 earnings guidance

• | Fourth quarter 2015 earnings per share were impacted $0.05 due to lower than expected retail loads from warmer weather

• | Construction continues at Carty with the company currently targeting an in service date in July 2016

• | Initiating 2016 earnings guidance of $2.20 to $2.35 per diluted share

PORTLAND, Ore. — Portland General Electric Company (NYSE: POR) today reported net income of $172 million, or $2.04 per diluted share, for the year ended Dec. 31, 2015. This compares with $175 million, or $2.18 per diluted share, for 2014. Net income was $51 million, or 57 cents per diluted share, for the fourth quarter of 2015 compared with $43 million, or 55 cent s per diluted share, for the comparable period of 2014. Looking forward, the company is initiating full-year 2016 earnings guidance of $2.20 to $2.35 per diluted share.
“Our financial results reflect strong operating performance despite the warmest year on record in Oregon,” said Jim Piro, president and CEO. “Our delivery system and generating facilities operated extremely well, we achieved a fair outcome in our 2016 general rate case, and employees across the company took necessary actions in response to the financial impacts of weather early in the year.”
2015 earnings compared to 2014 earnings
Annual earnings per diluted share decreased year over year due to lower energy sales as a result of historically warm weather, lower-than-expected hydro and wind generation across the whole year, and lower-than-expected federal production tax credits as a result of the lower wind generation. These factors were partially offset by earnings from placing Port Westward Unit 2 and the Tucannon River Wind Farm in service, increased AFDC from Carty construction, and the company’s management of operating and maintenance expense. Improving economic conditions and expansion of large high-tech industrial customers contributed to weather-adjusted load growth of more than 2 percent for the year, excluding one large paper customer.

Company Updates
Carty Generating Station
Construction is continuing on the Carty Generating Station, a 440 MW natural gas-fired baseload power plant near Boardman, Ore. On Dec. 18, 2015, PGE declared the general contractor responsible for engineering, procurement and construction in default under multiple provisions of the Carty construction agreement and terminated the agreement. Two sureties, Liberty Mutual and Zurich North America, have provided a performance bond of $145.6 million under the construction agreement. PGE required the original contractor to enter into the performance bond to guarantee satisfactory completion of the project in the event the contractor failed to fulfill its obligation under the construction agreement. Following termination of the construction agreement, PGE, in consultation with the sureties, brought on new contractors, and construction resumed during the week of Dec. 21, 2015.
“PGE’s decisive action to replace the general contractor on Carty was done in the best interest of our stakeholders,” Piro said. “We remain committed to delivering this important new baseload resource that will help us continue to serve our customers with the safe, reliable and affordable power they need for years to come.”
As of Dec. 31, 2015, PGE had invested $424 million in Carty, including $41 million of AFDC, which was included in Construction Work in Progress (CWIP) for the project. PGE currently estimates that the total capital expenditures for Carty will range from $620 million to $655 million, including AFDC, and is targeting an in service date in July 2016. PGE is currently in discussions with the sureties regarding their obligations under the performance bond. The company believes that the sureties will have an obligation under the performance bond to contribute funds toward the completion of Carty. However, the sureties have not yet made a determination with respect to their obligations. Accordingly, the amount of potential recovery of costs under the performance bond remains uncertain and cannot be reasonably estimated at this time. For additional information on Carty construction refer to PGE’s Form 10-K for 2015 issued on Feb. 12, 2016.
2016 General Rate Case
In November 2015, PGE filed final updated power costs and an updated retail load forecast with the Oregon Public Utility Commission (OPUC), and the OPUC issued an order resulting in an overall price increase of approximately 0.7 percent which reflects:
•Return on equity of 9.6 percent;
•Capital structure of 50 percent debt and 50 percent equity;
•Cost of capital of 7.51 percent;

• | Rate base of $4.4 billion;

• | Annual revenue increase of $12 million.

The net annual revenue requirement increase will be effective in two phases. A $44 million decrease, representing a 2.5 percent decrease in customer prices effective Jan. , 2016, and a $57 million annualized revenue increase will be effective when Carty is placed into service, provided that occurs by July 31, 2016.
The order issued by the OPUC authorized the inclusion in customer prices of capital costs for Carty of up to
$514 million, including AFDC, as well as its operating costs at such time the plant is placed in service provided that occurs by July 31, 2016.
In the event costs incurred by PGE to complete Carty, less any amounts received from the sureties, exceeds the OPUC’s approved amount of $514 million, the company would seek approval to recover the excess amounts in
Page 2

customer prices in a subsequent general rate case (GRC) proceeding. However, there is no assurance that such recovery would be granted by the OPUC.
If the Carty in-service date were to be delayed beyond July 31, 2016, PGE would pursue one or more alternative avenues to obtain OPUC approval for the inclusion of Carty costs in customer prices. Under such circumstance, the company might not be able to recover some, or all, of the net revenue requirements for Carty from the date Carty is placed into service until the time when new approved customer prices are effective for Carty.
Fourth-quarter operating results
Net income for the fourth quarter of 2015 was $51 million, or 57 cents per diluted share, compared with
$43 million, or 55 cent s per diluted share, for the fourth quarter of 2014. The increase in quarterly earnings per diluted share was primarily due to the incremental earnings from Port Westward Unit 2 and the Tucannon River Wind Farm being placed in service and the company’s management of operating and maintenance expense.
Retail revenues increased $4 million, or 1%, in the fourth quarter of 2015 compared with the fourth quarter of 2014, which was driven primarily by a 1 percent price increase authorized by the OPUC in the company’s 2015 GRC, which was effective Jan. 1, 2015. The price increase was largely the result of the additions of Port Westward Unit 2 and the Tucannon River Wind Farm, partially offset by lower estimated power costs for 2015. Weather in the fourth quarter of 2015 had a comparably negative impact on revenues as weather in the fourth quarter of 2014.
Net variable power costs (NVPC), which consist of purchased power and fuel expense net of wholesale revenues, decreased $14 million in the fourth quarter of 2015 compared to the fourth quarter of 2014. The decrease is largely due to a 7 percent percent decrease in the average variable power cost per MWh resulting from increases in energy received from the company’s generating resources combined with a 5 percent increase in the average price per MWh of wholesale power sales, net of a 4 percent decrease in the volume of wholesale power sales.
Total operating and maintenance expense was $136 million in the fourth quarter of 2015 compared with $139 million in the fourth quarter of 2014. The $3 million, or 2 percent, decrease was largely due to a $3 million reduction in high-voltage service costs, which were offset in revenues, $2 million related to the economic shutdown of Boardman and lower maintenance costs at several hydro facilities, offset by a $2 million increase related to the additions of Port Westward Unit 2 and the Tucannon River Wind Farm.
Depreciation and amortization expense was $1 million higher in the fourth quarter of 2015 compared with the fourth quarter of 2014. A $7 million higher expense resulting from capital additions was largely offset by a
$6 million reduction from the amortization of deferred regulatory liabilities for the Trojan spent fuel settlement and tax credits as they were refunded to customers in 2015.

Total retail revenues increased $12 million, or 1%, in 2015 compared with 2014, primarily due to the effect of the following:

• | An $11 million increase in revenues related to a 0.6% increase in retail energy deliveries, consisting of 5.5% and 0.2% increases in industrial and commercial deliveries, respectively, partially offset by a 1.8% decrease in residential deliveries; and

• | A $4 million net increase due to a $32 million increase that related to higher average retail prices resulting from the Jan. 1, 2015, price increase authorized by the OPUC in the company’s 2015 GRC, which was net of a $28 million decrease due to various supplemental tariff changes, including $20 million in customer credits in 2015 related to proceeds received in connection with the settlement of a legal matter regarding the operation of the ISFSI at the former Trojan nuclear power plant site and tax credits, all of which are offset in Depreciation and Amortization expense.

Net variable power costs decreased $45 million for 2015 compared with 2014, primarily driven by an 8% decline in the average variable power cost per MWh combined with a 2% increase in the volume of wholesale power sales, net of a 9% decrease in the average price per MWh of wholesale power sales. The 2015 GRC had
Page 4

estimated lower gas and power prices in 2015 and therefore, anticipated a decrease of approximately $60 million in NVPC from the 2014 baseline, with customer prices set accordingly.
For 2015, actual NVPC, as calculated for regulatory purposes under the power cost adjustment mechanism, was $3 million below the 2015 baseline NVPC. In 2014, NVPC was $7 million below the anticipated baseline.
Total operating and maintenance expense was $507 million in 2015 compared with $484 million in 2014. The $23 million, or 5 percent, increase is primarily due to the following:

• | $9 million in costs associated with the additions of Port Westward Unit 2 and the Tucannon River wind farm;

• | $14 million in administrative and general costs including a $5 million increase in information technology expenses, an increase of $3 million in non-labor and outside services expenses, a $3 million increase in injuries and damages resulting from insurance recoveries received in 2014, and a $1 million increase in compensation and benefits expense.

Depreciation and amortization expense in 2015 increased $4 million, or 1%, compared with 2014. A $26 million higher expense resulting from capital additions was largely offset by a $22 million reduction from the amortization of deferred regulatory liabilities for the Trojan spent fuel settlement and tax credits as they were refunded to customers in 2015. An increase in asset retirement obligation expenses and amortization of costs previously deferred for four capital projects as authorized in the company’s 2011 GRC, were partially offset by amortization of gains recorded on the sale of assets. The overall reduction in expenses resulting from the amortization of the regulatory liabilities is directly offset by corresponding reductions in retail revenues.
Interest expense increased $18 million, or 19%, in 2015 compared with 2014 as $9 million resulted from lower allowance for borrowed funds used during construction. In December 2014, PW2 and Tucannon River were placed into service resulting in a lower average CWIP balance, the basis for AFDC. In addition, $7 million related to a 7% increase in the average balance of debt outstanding.
Other income, net was $22 million in 2015 compared with $38 million in 2014. The decrease was primarily due to a $16 million decrease in the allowance for equity funds used during construction resulting from the lower average CWIP balance.
Income tax expense decreased $16 million, or 26%, in 2015 compared to 2014, with the effective tax rate decreased to 20.7% for 2015 from 26.0% for 2014. Lower pre-tax income accounted for $7 million of the decrease in income tax expense. A $14 million increase in production tax credits in 2015, resulting primarily from the addition of Tucannon River wind generation, was partially offset by a $5 million relative effect of lower AFDC equity.
2015 earnings guidance review
PGE initiated full-year 2015 earnings guidance on Feb. 13, 2015 of $2.20 to $2.35 per diluted share. On April 28, 2015, guidance was lowered to $2.05 to $2.20 after warm weather impacted earnings by $0.20 in the first quarter. In conjunction with lowering guidance, management also committed to monitoring financial results and looking for opportunities to temporarily reduce operating costs. For the remainder of 2015 the company successfully managed its O&M spending and made temporary reductions in an effort to offset the impact of the weather in the first quarter. Despite these efforts, continued warm temperatures were compounded by poor hydro and wind conditions which led to higher replacement power costs and fewer than estimated production tax credits for the year. In the final quarter of the year, warm temperatures again impacted earnings by $0.05, resulting in a $0.25 EPS impact of weather for the full-year 2015.

2016 earnings guidance
PGE is initiating full-year 2016 earnings guidance of $2.20 to $2.35 per diluted share. Guidance is based on warmer than normal weather and lower wind production in January 2016, which resulted in approximately an $0.08 impact on earnings. Additional assumptions include the following:

• | Retail deliveries growth of approximately 1 percent weather adjusted excluding one large paper customer;

• | Average hydro conditions;

• | Wind generation based on five years of historical levels or forecast studies when historical data is not available;

• | Normal thermal plant operations;

• | Operating and maintenance costs between $515 and $535 million, in line with the GRC;

• | Depreciation and amortization expense between $315 and $325 million; and

• | Carty Generating Station in service by July 2016 at approximately the OPUC authorized capital amount of $514 million.
