Portland General Electric announces third quarter 2016 results

• | Carty Generating Station (Carty) is operating exceptionally well

• | Draft 2016 Integrated Resource Plan (IRP) is available and final will be filed with the Oregon Public Utility Commission (OPUC) in mid-November

• | Based upon retail deliveries year-to-date, full-year retail load growth guidance has been reduced from 1 percent to zero

• | Reaffirming 2016 earnings guidance of $2.05 - $2.20 per share

PORTLAND, Ore. — Portland General Electric Company (NYSE: POR) today reported net income of $34 million, or 38 cent s per diluted share, for the third quarter of 2016. This compares with net income of $36 million, or 40 cent s per diluted share, for the third quarter of 2015. The decrease in third quarter earnings per diluted share was a result of a reduction in sales volume due to mild temperatures, a decrease in deliveries in the commercial and industrial sectors in the third quarter of 2016 in comparison to the third quarter of 2015, and expenses related to Carty not included in customer prices. These decreases were partially offset by the incremental earnings associated with the OPUC approved Carty capital costs being placed in-service, an increase in the decoupling collection, a gain on the non-qualified benefit trust and other miscellaneous items.
“We are reaffirming our guidance of $2.05-$2.20 for the year,” said Jim Piro, CEO and president of Portland General Electric. “While we revised our 2016 load forecast to be flat to 2015 related to softening in the industrial and commercial sectors, we still see positive growth ahead based on the continued strength of our local economy.”
Company Updates
Carty
PGE placed Carty, a 440 megawatt natural-gas fired baseload generating resource near Boardman, OR, into service on July 29, 2016. The plant is operating as designed and had a 92 percent availability rate through September. Beginning August 1, 2016, PGE began recovering the $514 million of capital costs, as well as the plant’s operating costs approved as part of the 2016 General Rate Case (GRC) in customer prices. As of September 30, 2016, PGE had $615 million recorded as plant in-service related to Carty. The company currently estimates that the total capital expenditures for Carty, including allowance for funds used during construction, will be approximately $640 million to $660 million. This cost estimate does not reflect any offsetting amounts that may be received from the sureties

Exhibit 99.1
pursuant to the performance bond or from Abeinsa Abener Teyma General Partnership (Abeinsa), the contractor or Abengoa S.A., the contractor’s parent company.
PGE continues to pursue legal action against Liberty Mutual and Zurich North America, the two sureties that provided a $145.6 million performance bond on the Carty project. At the end of July 2016, the U.S. District Court of Oregon ruled against the sureties’ motion to stay the proceedings in U.S. District Court of Oregon and ruled in favor of PGE’s motion to enjoin the sureties from an International Chamber of Commerce arbitration proceeding filed by Abengoa under a parental guarantee on the project. As a result, the first phase of the case with the sureties -- which will determine whether PGE’s termination of the contractor was proper -- is currently scheduled to begin trial in the U.S. District Court of Oregon in June 2017. Additionally, in early October, the U.S. Bankruptcy Court granted PGE’s motion for relief from the stay imposed by Abeinsa’s Chapter 11 bankruptcy proceeding, and, on October 21, 2016, PGE filed a complaint in the U.S. District Court of Oregon against Abeinsa on the Carty project for failure to satisfy its obligations under the terms of the Carty construction agreement. Refer to the company’s Form 10-Q for the third quarter 2016 for additional details on the Carty project.
Integrated Resource Plan
PGE is finalizing its 2016 IRP and expects to file it with the OPUC in mid-November. The plan continues to reflect a shift to a less carbon-intensive supply portfolio consistent with the new Oregon Clean Electricity and Coal Transition Plan which calls for 50 percent renewables by 2040. The 2016 IRP addresses the need for additional resources to meet the law’s requirements of 20 percent renewables by 2020 and to replace energy and capacity from PGE’s Boardman plant, which will cease coal-fired operations at the end of 2020. Actions identified through 2020 are also expected to offset expiring purchase power agreements and integrate variable energy resources, such as wind or solar generation facilities.
The proposed four-year Action Plan associated with the draft IRP includes a minimum of 135 MWa of new cost-effective energy efficiency, 77 MW of new demand response, and the addition of approximately 175 MWa in new qualifying renewable resources. The plan also identifies the need for up to 850 MW of new capacity resources, which includes 375-550 MW of long-term dispatchable resources and up to 400 MW of annual or seasonal equivalent capacity resources, to meet reliability needs.
The final IRP plan filed with the OPUC may include modifications to the draft. Acknowledgment of the 2016 IRP is targeted for mid-2017. Upon acknowledgment, PGE will request approval from the OPUC to issue one or more Requests for Proposals to acquire needed resources.
Weather-adjusted load growth forecast flat for 2016
PGE is reducing its prior full-year 2016 load growth estimate from 1 percent to flat in comparison to 2015, weather-adjusted and excluding one large paper company. This change is driven by decreased full year growth expectations for the commercial and industrial sectors due to lower third quarter actual deliveries. Industrial growth in the high tech sector has slowed from the rapid increases seen in recent years and, in 2016, these increases were offset by decreases in deliveries to metals and solar manufacturing customers resulting from operational changes and layoffs announced earlier in the year. In addition, energy efficiency continues to impact growth, with building codes and standards likely reducing energy deliveries beyond the impact of energy efficiency programs. Despite weakness in deliveries growth for 2016, economic fundamentals remain strong, including continued population growth in PGE’s service area, low unemployment rates and a robust underlying industrial sector, all of which support future growth.

Total revenues for the three months ended September 30, 2016 increased $8 million compared to the three months ended September 30, 2015, comprised primarily of a $19 million increase in wholesale revenues partially offset by an $11 million decrease in retail revenues.
The change in retail revenues resulted from the following:

• | A $19 million decrease resulting from a $34 million reduction in revenue related to 7.6% lower retail energy deliveries due to unfavorable weather conditions and a decrease in deliveries to commercial and industrial customers, partly offset by an increase of $15 million that resulted from customer price changes. Energy deliveries to residential and commercial customers decreased 7.5% and 5.7%, respectively, due in part to the effects of more moderate weather, and energy deliveries to industrial customers decreased 10.8%, largely due to the closure of a large paper customer that ceased operations in late 2015. PGE’s 2016 GRC took the loss of this customer into consideration and incorporated its effects into prices and load forecasts resulting in minimal impact on net income; and

• | Supplemental tariffs decreased $5 million as a $7 million reduction in collection, which ended in 2015, for certain capital projects was partly offset by increases of $2 million for the combination of property sales gains in 2015 and the timing of the Trojan spent fuel refund to customers; partially offset by

Exhibit 99.1

• | An $11 million increase resulted from other tariffs including a $9 million increase in estimated collections under the decoupling mechanism.

Net variable power costs (NVPC) (purchased power and fuel expense, net of wholesale revenues) for the three months ended September 30, 2016 decreased $20 million when compared with the three months ended September 30, 2015. The decrease was driven by a 66% increase in wholesale revenues, a 3% decrease in the average variable power cost per MWh, partially offset by a 3% increase in total system load. The increase in wholesale revenues was driven primarily by a 2% increase in the average wholesale sales price, combined with a 63% increase in wholesale sales volume. For the three months ended September 30, 2016, actual NVPC was $3 million above the baseline, while the three months ended September 30, 2015 actual NVPC was $6 million above baseline NVPC.
Generation, transmission and distribution expense increased $5 million, or 8%, in the three months ended September 30, 2016 compared with the three months ended September 30, 2015 driven primarily by $3 million of expense for Carty (placed in service in 2016).
Administrative and other expense increased $4 million, or 7%, in the three months ended September 30, 2016 compared with the three months ended September 30, 2015. The increase was primarily due to a $3 million increase in legal costs related to Carty.
Depreciation and amortization expense increased $3 million in the three months ended September 30, 2016 compared with the three months ended September 30, 2015. The increase was primarily driven by $6 million additional expense due to capital additions, offset by a $5 million decrease that resulted from the completion of the amortization of the regulatory asset for four capital project deferrals as authorized in the company’s 2011 GRC. Increases or decreases in expense resulting from amortization of regulatory assets or liabilities are directly offset in revenues.
Other income, net remained flat for three months ended September 30, 2016 compared with the three months ended September 30, 2015. This was due to a decrease in the allowance for equity funds used during construction resulting from lower average construction work in progress balances, primarily related to the Carty project, offset by gains on the non-qualified benefit trust.
Income tax expense was $6 million in the three months ended September 30, 2016 compared with $8 million in the three months ended September 30, 2015, with effective tax rates of 15.0% and 18.2%, respectively. The decrease in income tax expense and effective tax rate was primarily due to lower pre-tax income partially offset by a decrease in production tax credits.
2016 earnings guidance
PGE is reaffirming its revised 2016 guidance of $2.05 - $2.20 per diluted share. The guidance is based on the following assumptions:

• | Flat retail load for the full-year, weather-adjusted and excluding one large paper company;

• | Average hydro conditions for the remainder of the year;

• | Wind generation for the remainder of the year based on 5 years of historic levels or forecast studies when historical data is not available;

• | Normal thermal plant operations;

• | Operating and maintenance costs between $515 and $535 million; and

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