Chelan PUD to supply hydropower to Avista

Avista and Chelan County Public Utility District (PUD) in Washington State have finalized a contract for renewable hydropower from two Chelan PUD hydropower projects on the Columbia River. The contract increases Avista’s carbon-free resources in its energy portfolio, helping achieve the company’s clean electricity goals and supporting Washington State’s Clean Energy Transformation Act goals as well.

The “slice” contract provides Avista with 5% of the output from Chelan PUD’s 624-MW Rock Island and 1,236.6-MW Rocky Reach hydropower projects from 2024 through 2033. This contract complements an existing contract between Avista and Chelan PUD and will mean 10% of the renewable hydropower output from the two Chelan PUD projects will supply Avista customers.

The contract is the result of Avista’s 2020 Renewables Request for Proposals that solicited up to 300 MW of clean, existing or new, renewable resources. The request was aligned with Avista’s 2020 Integrated Resource Plan, which identified a need for new renewable energy.

“We’re pleased with the collaborative approach during our negotiations with Avista as we work to deliver more renewable energy to its customers in support of a healthy environment and strong economy in the Pacific Northwest,” said Chelan PUD General Manager Steve Wright. “This partnership also supports our long-term power marketing strategy toward longer 10-year contracts, bringing value to our customer-owners.”

“Avista was founded on renewable hydropower more than 130 years ago. We are proud to partner with Chelan PUD to bring more clean, reliable and affordable energy to our customers,” said Jason Thackston, Avista’s senior vice president of energy resources. “This brings us closer to our goal to serve customers with 100% clean electricity by 2045 and 100% carbon neutral resources by 2027.”

Avista recently filed its 2021 Electric Integrated Resource Plan in both Washington and Idaho. The plan will be amended to reflect this new contract.

Avista and Chelan PUD are both host utilities for HYROVISION International 2021, scheduled for July 27 to 29 in Spokane, Wash.
