ESA Solar Energy, a solar and energy storage project developer, has sold the 150 MW Salzburg battery storage project in Michigan, U.S., to renewable energy company Ørsted.

The companies did not disclose the transaction value.

Ascend Analytics, a provider of market intelligence and analytics solutions for the power industry, served as the exclusive advisor to ESA on the transaction through the Ascend Energy Exchange (AEX), which provides asset valuation, financial modeling, market outlook, and transaction advisory services.

According to the press release, the Salzburg battery storage is expected to support utility offtake requirements in the state, and has advanced through the permitting and interconnection processes, targeting a commercial operation date in 2029-2030.

“Michigan is poised for significant growth in clean energy and electrification, and energy storage will be essential to maintaining reliability as renewables scale. Acquiring this energy storage project fits well within our strategic growth ambitions, adding to our development pipeline and strengthening Ørsted’s expanding U.S. storage portfolio with a strategically located asset,” said James Giamarino, Chief Commercial Officer, Ørsted Americas. “We appreciate ESA’s partnership and disciplined development work in bringing this project to a fully permitted status.”

ESA said it has transacted over 8 GW of solar and energy storage developments and pre-construction assets over the past decade, and will provide post-close project development services for the Salzburg project.

7.2 GW of Energy Storage projects were acquired in Q1 2026, a 227% increase compared to the 2.2 GW in Q1 2025, according to Mercom’s Q1 2026 Energy Storage Funding and M&A report.

In April 2026, U.S.-based independent power producer Lydian Energy acquired the 1.5 GW Atlas North portfolio, comprising solar-plus-battery energy storage systems, in North America from Hanwha Renewables, a utility-scale solar and BESS projects developer. The financial terms of the acquisition were not disclosed.
