PERMANENT RULES
DEPARTMENT OF COMMERCE
[Filed January 28, 2025, 11:20 a.m., effective February 28, 2025]
Effective Date of Rule: Thirty-one days after filing.
Purpose: The proposed rule updates the average rate of emissions of greenhouse gas (GHG) emissions of new combined-cycle natural gas thermal electric generation turbines commercially available and offered for sale by manufacturers and purchased in the United States based on a survey of these turbines, as required under RCW
80.80.050. The proposed rule decreases the average available GHG emissions output from 925 pounds per megawatt hour (MWh) to 876 pounds per MWh. The updated average rate of emissions of GHG emissions will be used by the department of ecology and energy facility site evaluation council to implement Washington's baseload electric generation performance standard as provided for under chapter
80.80 RCW.
Citation of Rules Affected by this Order: Amending WAC 194-26-020.
Statutory Authority for Adoption: RCW
80.80.050.
Adopted under notice filed as WSR 24-18-107 on September 3, 2024.
Changes Other than Editing from Proposed to Adopted Version: Changed the average available GHG emissions output from 863 to 876 pounds per MWh to account for the removal of a power plant in the survey of natural gas thermal electric generation turbines based on stakeholder comments.
