Cypress Creek Doubles Portfolio With $4.5 Billion Arkansas Solar-Storage Acquisition

New updates have been reported about Cypress Creek Renewables.

Cypress Creek Renewables has acquired the 2.45 GW Steel River solar project with 2.9 GWh (720 MW) of battery storage in Mississippi County, Arkansas, from Swift Current Energy, in a deal that will roughly double Cypress Creek’s operating and under-construction portfolio to nearly 7 GW once built out. The company positions Steel River as a flagship asset that underscores its ability to develop, finance, and operate large-scale energy infrastructure as U.S. power demand accelerates.

The project, among the largest solar-plus-storage facilities in the United States, carries an estimated capital cost exceeding $4.5 billion and is structured in three phases of about 815 MW of solar and 240 MW / 960 MWh of storage each, with all phases targeted to be in service by 2029. For Cypress Creek, Steel River adds scale in a market where solar and storage represented roughly 85% of new U.S. generation capacity in 2025, while also enhancing grid reliability, peak-demand coverage, and price stability in the region, delivering more than $300 million in projected lifetime local tax revenues and leveraging American-made steel and domestically produced solar modules to align with U.S. manufacturing and energy-security priorities.
