Integrated Resource Plan
Mossyrock – One of Seven of Our Dams
The Integrated Resource Plan (IRP) is a tool to help Tacoma Power plan for an uncertain future so we can continue to meet our customers’ needs for decades to come. Approximately every four years, we complete a full refresh of the IRP. We also revisit and make small updates to the plan between the larger refresh years. In 2024, Tacoma Power completed a full refresh of the IRP.

- Clean Energy Implementation Plan
-
In 2019, Governor Jay Inslee signed into law the Clean Energy Transformation Act (CETA), which commits the State of Washington to an electricity supply free of greenhouse gas emissions by 2045. The landmark law imposes new clean energy mandates on electric utilities in Washington as well as planning and reporting requirements. One of those new requirements is that utilities complete a Clean Energy Implementation Plan (CEIP) by January 1, 2022 and every four years thereafter.

- Tacoma Power Conservation Potential Assessment 2024-2043
-
In 2023, the Tacoma Public Utility Board adopted a ten-year 2024-2033 conservation potential and a two-year 2024-2025 conservation target based on the 2024-2043 Conservation Potential Assessment (CPA). The CPA helps us determine where cost-effective energy efficiency is and is used develop conservation program efforts. The results of a CPA feed into our Integrated Resource Plans (IRPs) to help us optimize our electric supply-side and demand–side resources. The next assessment will be conducted in 2025.

-
Demand response saves electricity during times of high demand. Consumers play a significant role in the operation of the electric grid by reducing or shifting their electricity usage during peak periods in response to time-based rates or other forms of financial incentives. Engaging customers in demand response efforts includes offering time-based rates such as time-of-use pricing, critical peak pricing, variable peak pricing, real-time pricing, and critical peak rebates. It also includes direct load control programs, which allow power companies to cycle air conditioners and water heaters on and off during periods of peak demand in exchange for a financial incentive and lower electric bills.
