Portland General Electric Announces Third Quarter 2023 Results
•Reached constructive global settlement stipulation in 2024 GRC, including updates to the power cost recovery framework
•Third quarter results reflect challenging weather, power market volatility, and continued investment to support grid resiliency, customer growth and decarbonization
•Narrowing 2023 adjusted earnings guidance from $2.60 to $2.75 to $2.60 to $2.65 per diluted share to reflect the impact of third quarter power cost results
PORTLAND, Ore. -- Portland General Electric Company (NYSE: POR) today reported net income based on generally accepted accounting principles (GAAP) of $47 million, or $0.46 per diluted share, for the third quarter of 2023. This compares with GAAP net income of $58 million, or $0.65 per diluted share, for the third quarter of 2022.
“While challenging power market conditions impacted our results in the quarter, we made important progress to reduce risk and reinforce our long-term growth trajectory,” said Maria Pope, PGE President and CEO. “In particular, we were pleased to reach a constructive settlement in our General Rate Case, which improved power cost risk management. We also received exciting news that the Department of Energy awarded three grants that reinforce the work we are doing to advance the clean energy transition in collaboration with regional partners.”
Third Quarter 2023 Compared to Third Quarter 2022
Total revenues increased due to higher demand from digital customers and increased recovery of power costs, partially offset by lower residential and commercial usage. Purchased power and fuel expense increased primarily due to less favorable power market conditions resulting from periods of extreme summer heat. Operating and administrative expenses increased due to higher grid maintenance and resiliency costs and higher generation maintenance costs. Depreciation and amortization expense and interest expense increased due to ongoing capital investment. Other income decreased due to a prior year settlement gain from the buyout of a portion of PGE's post-retirement medical plan that did not recur.
Company Updates
2024 General Rate Case Global Settlement Stipulation
On October 6, 2023, PGE and stakeholders reached a settlement that resolves remaining issues in PGE's general rate case. Terms of the agreement and the resulting stipulation were submitted to the Oregon Public Utility Commission (OPUC) in Docket UE 416. After adjusting for the effects of settled items, PGE's adjusted annual revenue requirement increase is $391 million.
1

Key issues resolved include a provision allowing recovery of certain costs during Reliability Contingency Events (as defined in the settlement) at an 80/20 sharing ratio, inclusions of incremental Net Variable Power Costs (NVPC) for additional capacity contracts, the establishment of a balancing account for the recovery of routine vegetation management expenses, a tariff filing for residential and small commercial customers weather-normalized decoupling, withdrawal of the proposal for associated storage from the Renewable Adjustment Clause, and updates to PGE’s Income Qualified Bill Discount program.
The stipulations remain subject to OPUC approval, with new customer prices effective January 1, 2024.
Wildfire Mitigation Automatic Adjustment Clause
On October 18, 2023, the OPUC adopted a stipulation agreed to by PGE and certain parties that allows PGE to begin amortizing $27 million of deferred wildfire mitigation costs, comprised of $23 million related to the September 30, 2023 deferred operating expense balance of $31 million and $4 million for capital related revenue requirement. The $27 million will be amortized over a one-year period beginning October 20, 2023. PGE will recover the remaining deferred expense balance in future periods to be determined in a later proceeding. In January 2024, PGE will begin collecting forecasted wildfire mitigation costs under the wildfire mitigation automatic adjustment clause.
U.S. Department of Energy Awards
In October 2023, PGE and partner organizations were awarded the following:
•U.S. Department of Energy (DOE) Regional Clean Hydrogen Hub—The U.S DOE selected the Pacific Northwest Hydrogen Association’s PNWH2 Hub for award negotiations as one of the Regional Clean Hydrogen Hubs. PGE and partner organizations’ project concept proposed as part of the PNWH2 Hub would utilize the site of the former Boardman Coal Plant to locate a potential new facility to produce green hydrogen to generate clean electricity. DOE and the Pacific Northwest Hydrogen Association will negotiate the final funding and scope for the hub beginning this fall as part of a multi-year process.
•U.S. DOE Bethel-Round Butte Transmission Line Upgrade—The U.S. DOE selected the Confederated Tribes of Warm Springs (CTWS), in partnership with PGE, for a $250 million grant to upgrade the existing 230 kV Bethel-Round Butte Transmission line to 500 kV. The added capacity will increase resiliency of the transmission system and enable new carbon-free generation in Central Oregon.
•U.S. DOE Smart Grid Chip—The U.S. DOE selected a PGE led consortium for a $50 million grant for the Smart Grid Chip project. The project will enable real-time information at each meter to improve the visibility of the electrical system and enhance reliability and grid management.
PGE continues to pursue multiple areas under federal legislative programs for potential grant funding of projects.
Voluntary Renewable Energy Program
For the 14th year, PGE's voluntary renewable energy program, Green Future, was ranked number one by the U.S. Department of Energy’s National Renewable Energy Laboratory for the largest participation of business and residential customers in a renewables program of any electric utility in the U.S.
Quarterly Dividend
As previously announced, on October 20, 2023, the board of directors of Portland General Electric Company approved a quarterly common stock dividend of $0.475 per share. The quarterly dividend is payable on or before January 15, 2024 to shareholders of record at the close of business on December 26, 2023.

•Effective tax rate of 15% to 20%;
