Portland General Electric announces 2021 financial results and initiates 2022 earnings guidance
•Full-year 2021 financial results of $2.72 per diluted share
•Initiating 2022 earnings guidance of $2.75 to $2.90 per diluted share and reaffirming 4% to 6% long-term earnings per share growth using 2019 base year
•RFP shortlist targeted in Q2 with final selection by the end of 2022
PORTLAND, Oregon -- Portland General Electric Company (NYSE: POR) today reported net income based on generally accepted accounting principles (GAAP) of $244 million, or $2.72 per diluted share, for the year ended December 31, 2021. This compares with GAAP net income of $155 million, or $1.72 per diluted share, for the year ended December 31, 2020. After adjusting for the impact of the 2020 energy trading losses, non-GAAP net income was $247 million, or $2.75 per diluted share, for the year ended December 31, 2020. GAAP net income was $66 million, or $0.73 per diluted share, for the fourth quarter of 2021. This compares with GAAP net income of $52 million, or $0.57 per diluted share, for the fourth quarter of 2020.
“2021 was a year of strong growth and execution,” said Maria Pope, PGE President and CEO. “Against the backdrop of the ongoing pandemic, the historic ice storm and record heat, we focused on investments to improve reliability and resiliency. Looking ahead to 2022, we are advancing our use of technology and digital capabilities, accelerating our procurement of renewable resources, and deploying infrastructure to advance a smarter grid. We are seizing opportunities arising from the national momentum to address climate change and look forward to working with stakeholders and the communities we serve to create a stronger, sustainable and more resilient future for Oregon.”
2021 Year in Review
PGE is focused on leading Oregon to a clean energy future, helping customers maximize their energy journey with clean and innovative solutions that are also safe, reliable and affordable for all. Key strategic accomplishments in 2021 included:
•Worked with legislators and stakeholders to develop Oregon state law (HB 2021) establishing an electric sector decarbonization framework, including a mandated 80% reduction of baseline greenhouse gas from power served to Oregon retail customers by 2030 and revisions to legacy laws that will allow expanded utility program offerings;
•Issued an RFP to add 375 to 500 MW of renewables and 375 MW of non-emitting capacity by the end of 2024;
•Issued our inaugural Distribution System Plan, which provides a framework for electrifying the economy while achieving our environmental justice goals;
•Opened the new Integrated Operations Center and launched the Advanced Distribution Management System. These investments represent the cornerstone of our strategy to modernize grid operations and establish new physical and cyber security capabilities to monitor and protect assets while also improving incident response times;

•Continued our long-standing commitment to diversity, equity and inclusion and increased the representation of Black, Indigenous and People of Color as well as women in leadership across our company; and
•PGE, employees, retirees and the PGE Foundation donated $4.8 million, including $428 thousand invested through PGE and PGE Foundation grants and partnerships with culturally specific BIPOC organizations and $225 thousand to organizations serving five counties most impacted by the historic February 2021 ice storm.
2021 Earnings Compared to 2020 Earnings
Total revenue increased due to higher energy demand from strong economic growth. Net variable power costs were unfavorable, excluding the impact of the 2020 energy trading losses, due to high regional power prices, particularly in the third quarter. Operating and administrative expenses increased due to higher wildfire, vegetation management and storm expenses, higher employee wage and benefit expenses, and inflation pressures. Depreciation and amortization expense decreased due to plant retirements and the remeasurement of an asset retirement obligation recorded in 2020. Taxes other than income taxes increased due to higher property taxes.
2022 Earnings Guidance
PGE is initiating full-year 2022 earnings guidance of $2.75 to $2.90 per diluted share based on the following assumptions:
•An increase in energy deliveries between 2% and 2.5%, weather adjusted;
•Normal temperatures in its utility service territory;
•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;
•Capital expenditures of $660 million in 2022 and $650 million in 2023 through 2026;
•Average construction work in progress balance of $270 million;
•Operating and maintenance expense between $590 million and $610 million;
•Depreciation and amortization expense between $420 million and $440 million;
•Effective tax rate of 15% to 20%;
•Cash from operations of $575 to $625 million; and
•No new common equity to be issued for investment or operations.
Company Updates
General Rate Case
On January 18, 2022, PGE, OPUC staff, and certain customer groups filed a stipulation with the OPUC reflecting an agreement that resolves the annual revenue requirement, average rate base, and corresponding increase authorized in customer prices.
The agreement reflects a final revenue requirement that is based on:
•A capital structure of 50% debt and 50% equity;
•a return on equity of 9.5%;
•a cost of capital of 6.83%;
•an average rate base of $5.6 billion; and
•an annual revenue requirement increase of $74 million, which includes $64 million related to power costs.
On February 7, 2022, PGE, OPUC staff and certain customer groups filed a stipulation with the OPUC reflecting an agreement that resolved multiple pricing issues, including the rate spread model. Other elements of the case remain unsettled and all GRC items are subject to OPUC approval.

Decarbonization Framework and Resource Acquisition
HB 2021 creates a legislative framework to reduce baseline greenhouse gas emissions from power served to Oregon retail customers, based on the annual average of 2010, 2011 and 2012 amounts, by at least 80% by 2030, 90% by 2035, and 100% by 2040. Meeting these goals will require PGE to continue investing in new clean energy technologies that decarbonize our system while keeping the system reliable and affordable.
PGE initiated an RFP in April 2021 for 375 to 500 MW of renewable energy and 375 MW of non-emitting capacity. Initial bids were submitted in January 2022, with a shortlist expected in Q2 2022 and a final decision by the end of 2022.
In addition to generation resource acquisitions, PGE filed its inaugural Distribution System Plan at the Oregon Public Utilities Commission in October 2021, tying together the need for more clean and renewable resources and plans for an upgraded grid to support those resources.
Green Financing Framework
PGE has adopted a Green Financing Framework (“Framework”) under which we may issue bonds (“Green Bonds”) to finance or refinance investments in assets and projects that advance our sustainability goals.
In October 2021, PGE announced the successful placement of its inaugural $150 million green bonds under this framework, part of a $400 million placement. Proceeds of the $150 million in green bonds will be dedicated to refinancing PGE's investment in the Wheatridge Renewable Energy Facility, the first major renewable energy facility in North America to co-locate wind and solar generation with battery storage.
The bond issuance follows the recent renewal and $150 million increase of the company's $650 million revolving credit facility, which now includes a sustainability-linked pricing structure that links the company's borrowing costs to metrics related to its non-emitting generation capacity and the percentage of management comprised of women and employees who identify as black, indigenous, and people of color.
Quarterly dividend
As previously announced, on February 11, 2022, the board of directors of Portland General Electric Company approved a quarterly common stock dividend of $0.43 per share. The quarterly dividend is payable on or before April 18, 2022 to shareholders of record at the close of business on March 25, 2022.
Fourth Quarter and Full Year 2021 Earnings Call and Webcast — Feb. 17, 2022
PGE will host a conference call with financial analysts and investors on Thursday, Feb. 17, 2022, at 11 a.m. ET. The conference call will be webcast live on the PGE website at investors.portlandgeneral.com. A replay of the call will be available beginning at 2 p.m. ET on Thursday, Feb. 17, 2022, through 2 p.m. ET on Thursday, Feb. 24, 2022.
Maria Pope, President and CEO; Jim Ajello, Senior Vice President of Finance, CFO, and Treasurer; and Jardon Jaramillo, Senior Director, Investor Relations, Treasury, and Risk Management will participate in the call. Management will respond to questions following formal comments.
Non-GAAP Financial Measures
Management believes that excluding the effects of the previously disclosed 2020 energy trading losses provides a meaningful representation of the Company’s comparative earnings per share. The Company has adjusted this amount to maintain comparability between periods. The effect of the energy trading losses was $1.03 per diluted share on a full-year basis. PGE’s reconciliation of non-GAAP earnings for the year ended December 31, 2020 is below.
