Other provisions of SB 1547:

•establish RPS thresholds of 27% by 2025, 35% by 2030, 45% by 2035, and 50% by 2040, for the percentage of electricity that must come from renewable sources;

•limit the life of renewable energy credits (RECs) generated from facilities that become operational after 2022 to five years, but continue unlimited lifespan for all existing RECs and allow for the generation of additional unlimited RECs for a period of five years for projects online before December 31, 2022; and

•provide opportunity to pursue recovery of energy storage costs related to renewable energy in the Company’s Renewable Adjustment Clause (RAC) filings.

PGE expects to meet the 2025 RPS threshold.

EPA Regulations for Electric Generating Facilities—In April 2024, the United States Environmental Protection Agency (EPA) released final regulations pertaining to electric generation facilities. The regulations included:

•GHG regulations for new natural gas-based turbines and existing coal-based units, pursuant to section 111 of the Clean Air Act (CAA). The rule finalized: i) guidelines for GHG emissions from existing fossil fuel-fired steam generating electric units; and ii) revisions to existing performance standards for new, reconstructed, or heavily modified fossil fuel-fired stationary combustion turbine electric generating units. 

•Supplemental Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category (the ELG Rule), which applied to wastewater discharges from coal-based generating units and established pollution control requirements, building upon the 2015 and 2020 ELG Rules. The rule included a subcategory of requirements for coal plants that will be retired or repowered by the end of 2028 and provides additional compliance pathways for coal plants that retire by the end of 2034.  

•Updated Mercury and Air Toxics Standards (MATS), pursuant to section 112 of the CAA, which set emissions limits for filterable particulate matter for coal-based generating units. The rule reduced those limits from the standards that were originally set in 2012.

PGE continues to evaluate each of these rules to assess the impact it may have on the Company’s continuing investment in Colstrip, which could be material. Compliance with the rules would require material upgrades at
