Eolus completes all-cash sale of 127 MW Roccasecca BESS project to large US IPP
Today, Eolus signed and closed the sale of the Roccasecca stand-alone battery energy storage project, totaling 127 MW / 506 MWh, located in Boulder City, Nevada, USA. The transaction was completed as an all-cash sale to a large US IPP, who is a leading developer, owner, and operator of renewable energy projects with over twelve gigawatts of aggregate capacity. The project is currently under construction and is expected to reach commercial operation in 2026.
The transaction covers the transfer of all shares of the Roccasecca SPV to the buyer and a total cash payment, including cost reimbursement, of approximately USD $66.9 million to Eolus. Roccasecca marks Eolus’s fifth project sale in the U.S. market. Following an investment decision taken by Eolus’ board in mid 2025, construction of Roccasecca began in the fourth quarter.
As part of the transaction, the buyer assumes all rights and obligations associated with the project, including a 15-year tolling agreement, equipment supply agreements and project finance agreements negotiated and executed by Eolus. The buyer takes over construction management and will continue the buildout until completion, with Eolus supporting as required.
”Eolus continues its string of successful transactions in the U.S. Southwest with the Roccasecca deal. I’m proud to note that we are now a preferred partner to leading financiers and asset owners investing in power generation and energy storage assets. Eolus North America has earned a reputation as a solid contributor to the development of the U.S. energy supply.” says Hans-Christian Schulze, Country Manager, Eolus North America.
“We continue to generate healthy returns from a pipeline of renewable energy and battery projects, built up over more than ten years of presence in the U.S. market. We timed this deal flawlessly, handing over a derisked project, complete with contracted revenues, construction to term financing, and a sensible allocation of construction risk. Roccasecca shows how we leverage our experience to structure transactions for optimal value creation. I look forward to reinvesting our Roccasecca proceeds into new value creating opportunities in the Eolus pipeline”, adds Per Witalisson, CEO of Eolus.
