SOLV Energy shares are higher as investors react to a recent business update that underscored the company’s expanding operations-and-maintenance footprint and a marquee project win. The company said its O&M portfolio now exceeds 20 GW of utility-scale solar and storage capacity under management as of December 31, 2025, up more than 2 GW year over year, and highlighted what it called the largest single-site O&M award in its history.

The update pointed to the Darden project in California’s Central Valley as a flagship example of the company’s expanding role in running large, complex renewable assets. When fully online in 2028, Darden is expected to combine 1.6 GW of solar with 4.6 GWh of battery storage, positioning it as one of the largest solar-plus-storage projects in the U.S. and a major reference win for SOLV’s hybrid-asset operating capabilities.

For a newly public infrastructure-services provider, a growing O&M base can be viewed as improving visibility and durability relative to one-time construction revenue, especially as more solar plants add storage and require more sophisticated controls, high-voltage testing, and performance engineering. SOLV also highlighted its 24/7 NERC-compliant operations and control center covering 150 sites, plus HV testing and SCADA/network services—capabilities that can support repeat work, emergency response, and lifecycle upgrades as the installed base ages.
