RAI Energy, a Western U.S.-focused renewable energy development company, sold its Big River Energy project, comprising a 75 MWac solar photovoltaic system paired with a 300 MWh (4-hour) battery energy storage system, to an undisclosed strategic investor.
Located near Quincy Washington, adjacent to the Pacific Northwest’s data center clusters, the Big River Energy project is strategically designed to support the expanding power demands of hyperscale and cloud computing infrastructure.
The transaction positions the project to advance to notice to proceed, which is anticipated within the next 24 months as final development milestones are completed.
“This sale is a strong validation of the quality of the Big River Energy Farm project and of our team’s development platform,” said Mohammed S. Alrai, President and CEO of RAI Energy. “We are proud to have advanced this project to a stage where a strategic investor can take it forward to construction and operations. Big River reflects our focus on building high-value, bankable solar and storage assets that meet the growing need for clean, reliable capacity.”
Orric, Herrington & Sutcliffe and Kevin McSpadden Law Firm acted as the advisors to RAI Energy on the transaction.
RAI Energy has stated to have a record of developing more than 750 MW of utility-scale and distributed solar and energy storage projects.
Previously, RAI Energy International and Apex Energy Solutions sold the Vikings Energy project to Arevon Energy in October 2021. The Vikings project includes 157 MW solar capacity coupled with 150 MW/600 MWh battery energy storage systems.
According to Mercom’s Annual and Q4 2025 Solar Funding and M&A report, approximately 37.4 GW of solar projects were acquired in 2025, compared to 37.7 GW in 2024.
In March, Climate Fund Managers, an investment manager operating in emerging markets, and Erco Energía, a Colombian renewable energy project developer, entered into an agreement with Organización Terpel, a Colombian energy distribution and retail company, for the sale of their respective stakes in the 26.4 MW Pétalo del Norte de Santander I solar project, subject to regulatory approval.
