Portland General Electric Announces Second Quarter 2022 Results
•Revising 2022 GAAP basis earnings guidance from $2.50 to $2.65 to $2.60 to $2.75 per diluted share; initiating non-GAAP basis adjusted full-year 2022 earnings guidance of $2.74 to $2.89 which reflects the exclusion of previously disclosed deferral reductions related to 2020
•Continued strong energy delivery and customer growth, coupled with favorable power cost conditions
•Filed for amortization of 2021 Power Cost Adjustment Mechanism, 2020 Labor Day Wildfire and February 2021 Ice Storm deferrals
PORTLAND, Ore. -- Portland General Electric Company (NYSE: POR) today reported net income based on generally accepted accounting principles (GAAP) of $64 million, or $0.72 per diluted share, for the second quarter of 2022. This compares with GAAP net income of $32 million, or $0.36 per diluted share, for the second quarter of 2021.
“The region’s growth, driven by the semiconductor and digital technology sectors, relies upon safe, reliable, clean, affordable energy,” said Maria Pope, PGE president and CEO. “Our progress this quarter demonstrates our ongoing commitment to advancing Oregon’s clean energy goals and mitigating risk across our system to keep our customers safe, particularly during wildfire season and high heat. With the operational and financial progress we are making, PGE is positioned for long-term growth.”
Second Quarter 2022 Compared to Second Quarter 2021
Total revenues were driven by higher retail energy deliveries, due to continued growth in industrial demand, including high-tech and digital customers, offset by a reduction in the average price of deliveries due to a varying customer mix. Purchased power and fuel expense decreased due to strong hydro and power market conditions in 2022, and quarter over quarter tailwinds due to challenging market conditions in the second quarter of 2021. Operating and administrative expenses increased, driven by wildfire mitigation, grid resiliency and maintenance, enhancements to customer digital technology and higher professional services and insurance costs. Other income decreased due to declines in the value of the non-qualified benefit plan trust assets.
Company Updates
Major Deferral Amortization Request Filings
In July, PGE submitted amortization request filings to the OPUC for the 2021 Power Cost Adjustment Mechanism, 2020 Labor Day Wildfire, and February 2021 Ice Storm, representing $132 million of outstanding major deferrals. PGE anticipates resolution of these filings by the end of 2022 and plans to file an amortization request for the COVID-19 deferral, which has a $34 million balance as of June 30, 2022, in late 2022 or early 2023.

Renewable Energy and Non-Emitting Capacity Request for Proposal Update
The OPUC acknowledged PGE’s submitted shortlist of bids in the pending Renewable Request for Proposals (RFP) on July 15, 2022. The RFP is intended to procure at least 375 to 500 MW of qualifying renewable energy resources, approximately 375 MW of non-emitting dispatchable capacity resources, and up to 100 MW of renewable energy resources in support of the Green Future Impact program’s PGE supply option. PGE has since commenced negotiations with shortlist bidders and plans to finalize negotiations prior to the end of 2022 to allow sufficient time to capture expiring federal production tax credits for the benefit of customers.
The proposals for renewable energy resources provide various combinations of wind, solar, and battery storage options that include power purchase agreements (PPA) along with Company-owned resources. The proposals for non-emitting dispatchable capacity resources provide battery storage options and a pumped storage option that include PPAs along with Company-owned resources. The ultimate outcome of the RFP process may involve the selection of multiple projects for both renewable energy and non-emitting dispatchable capacity resources.
Wildfire Protection Plan Approved by the OPUC
In late April, the OPUC approved PGE’s 2022 Wildfire Mitigation Plan, the foundational document that implements the Company’s Wildfire Mitigation Program for assessing and addressing wildfire risks in PGE’s region. Core components of the plan include PGE’s risk assessment and modeling processes, system inspection, design and construction work, wildfire-related capital and technology investment plans, vegetation management plans and practices and proactive efforts employed during high-risk events. Customer and community safety is PGE’s highest priority, and this plan specifies efforts to address wildfire risks and remain in compliance with all relevant wildfire-related requirements.
Quarterly Dividend
As previously announced, on July 22, 2022, the board of directors of Portland General Electric Company
approved a quarterly common stock dividend of $0.4525 per share. The quarterly dividend is payable on or before October 17, 2022, to shareholders of record at the close of business on September 26, 2022.
2022 Earnings Guidance
PGE is revising its estimate for full-year 2022 GAAP earnings guidance from $2.50 to $2.65 to $2.60 to $2.75 per diluted sha re; initiating non-GAAP basis adjusted full-year 2022 earnings guidance of $2.74 to $2.89 which reflects the exclusion of previously disclosed $17 million deferral reductions related to the year ended 2020. These are 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;
•Operating and maintenance expense from between $620 million to $640 million, which includes the $17 million impact of released deferrals related to 2020;
•Depreciation and amortization expense between $420 million and $440 million;
•Effective tax rate of 15% to 20%;
•Cash from operations of $600 million to $650 million;
•Capital expenditures of $755 million; and
•Average construction work in progress balance of $270 million.

Non-GAAP Financial Measures
This press release contains certain non-GAAP measures, such as adjusted earnings, adjusted EPS an d adjusted earnings guidance. These non-GAAP financial measures exclude significant items that are generally not related to our ongoing business activities, are infrequent in nature, or both. PGE believes that excluding the effects of these items provides a meaningful representation of the Company’s comparative earnings per share and enables investors to evaluate the Company’s ongoing operating financial performance. Management utilizes non-GAAP measures to assess the Company’s current and forecasted performance, and for communications with shareholders, analysts and investors. Non-GAAP financial measures are supplementary information that should be considered in addition to, but not as a substitute for, the information prepared in accordance with GAAP.
Items in the periods presented, which PGE believes impact the comparability of comparative earnings and do not represent ongoing operating financial performance, include the following:
•Non-cash Wildfire and COVID deferral reversal charge associated with the year ended 2020, resulting from the OPUC’s 2022 GRC Final Order earnings test.
