SAN DIEGO, April 01, 2026 (GLOBE NEWSWIRE) -- SOLV Energy today highlighted its industry‑leading operations and maintenance (O&M) platform, with an O&M portfolio that exceeds 20 GW of utility-scale solar and storage capacity under management as of December 31, 2025, an increase of over 2 GW from the previous year. This scale reflects SOLV Energy’s growing role supporting large, complex renewable energy portfolios across the United States, with a focus on operational discipline, safety, and lifecycle performance.
SOLV Energy’s O&M portfolio includes large-scale projects such as the Darden project in California’s Central Valley. When fully online in 2028, Darden will combine 1.6 GW of solar with 4.6 GWh of battery storage, making it one of the largest solar‑plus‑storage projects in the United States and the largest single‑site O&M award in the company’s history. The project’s scale and hybrid configuration reflect SOLV Energy’s deep operating experience across both utility‑scale solar and large‑format energy storage assets.
SOLV Energy’s O&M portfolio is supported by integrated lifecycle services designed to maximize availability, reduce downtime, and protect long-term asset value. Key capabilities include:
- 24/7 NERC compliant Operations & Control Center providing remote monitoring and control for 150 sites nationwide
- Preventative and corrective maintenance, vegetation management, and fleetwide performance monitoring for solar and storage facilities
- NETA compliant HV testing, repairs, and upgrades to de-risk critical substation infrastructure
- SCADA engineering, commissioning, and retrofit services supported by in‑house performance engineering and asset‑level analytics
- Major component remediation and rapid return to service, including inverter, EBOS, and other critical equipment repairs
Together, these capabilities support reliable operation of large, complex solar and storage facilities and help asset owners maintain consistent performance across growing hybrid portfolios.
“As recent project wins demonstrate, power portfolios are growing in both scale and complexity, and they demand operators with the technical depth to manage them safely and reliably,” said George Hershman, CEO of SOLV Energy. “With more than 20 GW now under management, SOLV Energy is delivering the disciplined, lifecycle‑focused operations that asset owners and investors expect from long‑term infrastructure partners.”
