Chapters 173-441 and 173-446 WAC – Electricity Markets
Ecology proposes to update two rules:
- Chapter 173-441 WAC, Reporting of Emissions of Greenhouse Gases
- Chapter 173-446 WAC, Climate Commitment Act Program Rule
The purpose of these updates is to identify and establish compliance obligations for entities that import electricity to Washington from centralized electricity markets. Supporting changes to Chapter 173‑441 WAC will make sure appropriate data is available.
The centralized electricity markets to be addressed in the rulemaking include the:
- Energy Imbalance Market
- Extended Day Ahead Market
- Markets+ initiative underway by the Southwest Power Pool
The rule may also address other issues related to reporting of greenhouse gas emissions for entities importing electricity to Washington.
