Integrated resource plan

Puget Sound Energy (PSE) has completed the 2021 Integrated Resource Plan (IRP). The IRP is a planning exercise that evaluates how a range of potential future outcomes could affect PSE’s ability to meet our customers’ electric and natural gas supply needs. The analysis considers policies, costs, economic conditions and the physical energy system, and proposes the starting point for making decisions about what resources may be procured in the future.

The Final 2021 IRP report can be found under 2021 IRP > 2021 IRP Reports.

Electric IRP Highlights

PSE is committed to reaching the goals of the Clean Energy Transformation Act (CETA) and achieving carbon neutrality by 2030 and carbon free electric energy supply by 2045, and the electric resource plan presented reflects these changes and goals. It includes:

  • significant investments in renewable resources
  • accelerated acquisition of energy conservation
  • increased use of demand response
  • integration of distributed energy resources like residential solar and battery energy storage
  • reduced reliance on short-term market purchases in response to the changing western energy market
  • inclusion of alternative fuels to operate new generating plants

Natural Gas IRP

The natural gas resource plan focuses on significant, aggressive acquisition of conservation to meet all future customer needs. The cost-effective amount of conservation almost doubles compared to recent energy efficiency savings and current energy efficiency targets.
