SOLV Energy today announced the acquisition of Spartan Infrastructure, a high-voltage (HV) transmission contractor based in Mesa, Arizona. The acquisition represents a significant expansion of SOLV Energy’s capabilities in the transmission and distribution (T&D) sector and positions the company to play a diversified role in meeting the growing demand for resilient power infrastructure across the U.S.

The two companies have a long history of collaboration, having partnered on several major solar projects in the Southwestern, South Central and Mountain West regions of the United States. The acquisition is the culmination of a longstanding relationship and creates new growth opportunities for both organizations. Spartan’s specialized T&D experience strengthens SOLV Energy’s existing HV capabilities, enhancing its ability to deliver integrated, lifecycle solutions across the broad energy market, while providing Spartan with the scale and financial backing to pursue larger projects.

“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,” said George Hershman, CEO of SOLV Energy. “Spartan’s deep expertise in transmission infrastructure is a perfect complement to our capabilities, and we’re excited to continue our growth together.”

“I’m incredibly proud of the Spartan team for reaching this transformative milestone,” said Casey Maslonka, Co-Founder and President of Spartan Infrastructure. “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.”

The acquisition underscores SOLV Energy’s commitment to building a resilient, vertically integrated services offering to support the rapid expansion of the U.S. power grid across more forms of energy. The financial terms of the transaction were not disclosed.
