Ampacity, LLC

Ampacity, LLC is a leading U.S.-based provider of comprehensive structural and electrical solutions for clean energy transition projects. Headquartered in Monterey, California, Ampacity operates as part of Quanta Services’ family of companies—a major infrastructure contractor in North America’s utility sector.
Since its founding in 2014 (originally as RP Construction Services), Ampacity has delivered more than six gigawatts of fully engineered clean energy systems across the United States and Canada. The company specializes in end-to-end project execution—covering everything from initial engineering through procurement/kitting to mechanical/electrical installation—enabling seamless delivery for utility-scale solar installations.
Ampacity’s vertically integrated approach addresses critical industry needs by streamlining procurement processes, reducing overhead costs for clients such as EPCs (Engineering Procurement Construction firms), improving safety standards on-site through pre-kitted assemblies, and accelerating project timelines by making work more repeatable at scale. Their expertise positions them as a key partner to developers seeking reliable execution amid growing demand driven by data centers and advanced manufacturing facilities.
In early 2025, RP Construction Services was rebranded as Ampacity Renewables under Quanta Services to reflect expanded capabilities supporting large-scale renewable infrastructure development throughout North America.
