At RE+ 2025 in Las Vegas, SOLV Energy (“SOLV”) announced the continuing expansion of its services for solar, energy storage and transmission and distribution (T&D) with the acquisitions of Spartan Infrastructure (“Spartan”) and SDI Services (“SDI”). SOLV acquired Spartan, a leading high-voltage transmission contractor, in June 2025. The acquisition of Spartan enhances SOLV’s ability to self-perform complex T&D work and meet growing demand for transmission infrastructure. Spartan recently formed a 35kV overhead crew to support SOLV’s solar capabilities—aligning with an industry-wide shift toward overhead AC collection systems for greater efficiency and scalability.
Spartan’s longstanding utility partnerships also open new customer segments and revenue opportunities for SOLV. SOLV acquired SDI, a national foundational drilling and pile installation specialist for solar and T&D projects, in January 2025. Together, these acquisitions strengthen SOLV’s ability to execute complex projects in diverse environments, drive technical innovation and deliver integrated solutions that create long-term value for the company’s customers.
SOLV Energy has also expanded its national reach with the integration of CS Energy, a leading solar EPC in the Northeast and Mid-Atlantic regions. Effective immediately, CS Energy will operate under the SOLV Energy brand—strengthening SOLV’s presence in key markets and combining regional expertise with national scale. SOLV is now active in all U.S. ISOs with more than 1 GW of installed and awarded EPC capacity in nearly every market.
Scope of SOLV
The expanding scope of SOLV’s capabilities is underscored by the growing number of developers and independent power producers that are partnering with the company, including leading clean energy companies such as Clēnera, Clearway, Pine Gate Renewables, Arevon, Deriva Energy, DESRI, and Sol Systems. Recognized by both Engineering News Record and Solar Power World as one of the nation’s top solar and energy storage contractors, SOLV Energy continues to demonstrate superior scale, geographic reach and technical expertise.
“SOLV Energy’s performance this year reflects the strength of our partnerships and the trust our customers place in our ability to deliver at scale,” said George Hershman, CEO of SOLV Energy. “We’re proud to offer full lifecycle support—from development through long-term operations—while building lasting relationships with our partners and the communities we serve. RE+ is the best opportunity to come together as an industry, share ideas and solve the challenges that lie ahead. We’re excited to be part of that conversation.”
SOLV Energy CEO George Hershman will speak on the Main Stage at RE+ 2025 during the Executive Roundtable on the Future of Renewable Energy, taking place Tuesday, September 9, from 10:30 to 11:30 AM. He’ll join other industry leaders to talk about the challenges ahead and how companies like SOLV Energy are shaping the future of energy infrastructure.
