Avista files 2025 Clean Energy Implementation Plan with Washington Commission

The new plan outlines clean energy targets, community commitments, customer impacts and more

SPOKANE, Wash., Oct. 07, 2025 (GLOBE NEWSWIRE) -- On October 1, 2025, Avista Utilities, an operating division of Avista Corp. (NYSE: AVA), filed its 2025 Clean Energy Implementation Plan (CEIP) with the Washington Utilities and Transportation Commission.

This plan, required by Washington’s Clean Energy Transformation Act (CETA), is updated every four years and details Avista’s path toward a carbon-neutral electricity supply by 2030 and 100% renewable or non-carbon emitting supply by 2045.

Currently, more than half of Avista’s generating potential is produced by hydropower, biomass, wind, and solar. The new CEIP outlines how Avista will strengthen this foundation through energy efficiency, demand response, and more.

“As we plan for Washington’s energy future, our commitment remains the same as it’s been for over 135 years: to deliver safe, reliable energy while evolving to meet modern needs. This Clean Energy Implementation Plan marks the next chapter in our shared journey to power resilient, thriving communities," said Avista President and CEO Heather Rosentrater.

Ongoing feedback from Washington customers, community partners, Avista advisory groups, and other interested parties helped shape the new CEIP.

Some highlights of the 2025 CEIP include:

• Updated clean energy targets: Avista proposes increasing the amount of clean energy delivered to Washington customers from 66% in 2026 to 76.5% by 2029.
  
  
• Modern energy management: Between 2026 and 2029, Avista plans to launch new demand response programs that could reduce electricity usage by up to 55 megawatts (MW) during peak times, like the hottest summer afternoons or coldest winter mornings. These programs may include smart thermostats, battery storage, and other tools that help customers shift or lower their energy use when demand is highest.
  
  
• Energy efficiency programs: Avista will grow its energy-saving programs to help customers use less electricity without giving up comfort or convenience.
  
  
• Community engagement: As required by CETA, the plan emphasizes meaningful engagement with all communities, especially Named Communities, which are populations disproportionately affected by environmental, financial, and societal factors, among others.
