SOLV Energy expands with Spartan acquisition

SOLV Energy, an infrastructure services provider to the power industry, has expanded its operations by acquiring Spartan Infrastructure, a specialist in high-voltage (HV) transmission based in Mesa, Arizona.

The acquisition strengthens SOLV Energy’s presence in the transmission and distribution (T&D) sector and equips it to address the increasing demand for robust power infrastructure throughout the US.

SOLV Energy and Spartan Infrastructure have previously collaborated on several significant solar projects in the US.

SOLV Energy CEO George Hershman stated: “Bringing Spartan Infrastructure into the SOLV Energy family is highly strategic and enhances our ability to deliver an end-to-end solution for our clients.

“Spartan’s deep expertise in transmission infrastructure is a perfect complement to our capabilities, and we’re excited to continue our growth together.”

With Spartan’s expertise now part of its portfolio, SOLV Energy enhances its ability to offer comprehensive lifecycle solutions within the energy market.

Spartan’s specialised T&D experience is set to strengthen its existing HV capabilities, enabling it to deliver integrated solutions across a wider spectrum of energy markets.

Spartan Infrastructure co-founder and president Casey Maslonka stated: “I’m incredibly proud of the Spartan team for reaching this transformative milestone.

“Their dedication and hard work have built a strong foundation for our future as part of the SOLV Energy family. Together, we’re better positioned than ever to deliver exceptional value and performance to our customers and stakeholders.”

This development highlights SOLV Energy’s dedication to creating a resilient service offering that caters to the fast-paced expansion of the US power grid encompassing diverse forms of energy generation.

While details regarding financial aspects remain confidential, the acquisition indicates an important step towards meeting future infrastructure needs.

In May 2025, SOLV Energy obtained contracts to construct more than 6GW of utility-scale solar and storage projects across the US.
