SOLV Energy announced the expansion of its operations in solar, energy storage, and transmission and distribution (T&D) during the RE+ 2025 conference. The company confirmed the acquisition of two specialised firms, Spartan Infrastructure and SDI Services, thereby reinforcing its ability to manage complex projects throughout the United States.
Spartan Infrastructure, a company specialising in high-voltage transmission lines, was acquired in June 2025. This deal allows SOLV Energy to self-perform advanced T&D work while meeting growing demand for electricity transport infrastructure. Spartan recently assembled a 35kV overhead line crew to support SOLV’s solar installations using more efficient alternating current collection systems. Spartan’s longstanding partnerships with utility companies also grant SOLV broader access to new customer segments.
Technical and operational expansion in solar projects
In January 2025, SOLV Energy also acquired SDI Services, a national company specialising in foundational drilling and pile installation for solar and T&D projects. This integration enhances the group’s on-site technical capacity, enabling operations in diverse environments and the delivery of integrated solutions across the full project lifecycle.
At the same time, SOLV completed the integration of CS Energy, an engineering, procurement, and construction (EPC) solar company active in the Northeast and Mid-Atlantic regions of the United States. Now operating under the SOLV Energy brand, the merged entity strengthens the group’s regional footprint and complements its national operations with local expertise. The company is now active in all independent system operator (ISO) markets in the country, with over 1 GW of installed or awarded EPC capacity.
Extended partnerships with independent producers
This growth is accompanied by an increasing number of partnerships with developers and independent power producers. SOLV Energy is working with several major sector players, including Clēnera, Clearway, Pine Gate Renewables, Arevon, Deriva Energy, DESRI, and Sol Systems. These relationships support SOLV’s strategy to offer full lifecycle coverage, from project development through long-term asset operation.
SOLV Energy Chief Executive Officer George Hershman will speak during the Executive Roundtable on the future of renewable energy at RE+ 2025. He will address the challenges facing the sector and the infrastructure solutions being implemented by energy companies.
