2021 Clean Energy Implementation Plan (CEIP)
See PUD 3’s first CEIP required under Washington’s Clean Energy Transformation Act (CETA).
It covers the first 4-year interim compliance period beginning in 2022 and ending in 2025.
CETA requires electric utilities to prepare a CEIP every four years and it must:
- Propose interim targets for meeting CETA’s standards for greenhouse gas neutral electricity in 2030 and clean energy in 2045
- Identify specific targets for energy efficiency, demand response, and renewable energy
- Identify specific actions for meeting the interim targets and specific actions described above
- Ensure that all customers benefit from the transition to clean energy
Further requirements for the development of CEIPs are specified in Washington’s RCW 19.405.060 and Chapter 194-40 of the Washington Administrative Code.
