On October 30, 2025, Clearway Energy Group announced that it has signed a 20-year power purchase agreement and a 20-year energy storage agreement with the Public Utility District No. 2 of Grant County (Grant PUD) for the Royal Slope Energy Center, a 260 MW solar and 260 MW storage facility in Grant County, Washington. Wilson Sonsini Goodrich & Rosati advised Clearway on the transaction.

Grant PUD’s 2024 Integrated Resource Plan identified near-term energy and capacity needs to meet the utility’s reliability requirements and the State of Washington’s carbon goals. The power purchase and energy-storage agreements with the services provided by Clearway at its Royal Slope Energy Center will support Grant PUD in meeting its near-term targets for both solar and battery storage by 2028 and advance the utility closer to meeting its power-acquisition needs through 2030.

The Royal Slope Energy Center will generate enough electricity to power up to 87,000 homes. The project is sited on private, unincorporated land and will interconnect via the Vantage Substation, leveraging transmission infrastructure operated by Bonneville Power Administration.

The Wilson Sonsini team that advised Clearway on the transaction included Matt Bogdan and Nadia Senter.
