Clearway Signs Long-Term Contract to Deliver Wind Energy to Puget Sound Energy

• Clearway's first project in Montana will generate enough electricity to power over 116,000 homes each year

SAN FRANCISCO - Clearway Energy Group ("Clearway") announced today that it signed a 25-year power purchase agreement ("PPA") with Puget Sound Energy ("PSE") for the Haymaker wind farm, a 315 MW facility under development in Wheatland and Meagher counties Montana. Once operational, Haymaker will generate enough electricity to power approximately 116,000 homes each year.

"We are proud to partner with Puget Sound Energy in delivering low-cost clean energy to their customers and supporting their ambitious renewable energy goals," said Valerie Wooley, Senior Vice President of Origination at Clearway. "Reinforced by the Inflation Reduction Act, Haymaker represents a major investment in central Montana's economy, and we're eager to work with the community through development, construction, and our long-term stewardship of the project."

"This agreement with Clearway helps us meet some of the most ambitious laws in the nation while delivering on our customer's expectations for energy that is clean as well as safe, reliable and affordable," said Ron Roberts, PSE's senior vice president of Energy Resources. "We are proud to be a partner in developing Montana's wind resources and this is yet another milestone in our continued investment in the state's energy economy.

Haymaker is expected to provide millions in landowner payments and over $100 million in property tax revenue over the life of the project. Hundreds of well-paying union labor jobs will be created during construction and a permanent local workforce will operate and maintain the site.

Construction of the Haymaker Wind is scheduled to begin in 2026, with commercial operations expected by 2028.
