EPC Power has opened a new U.S. manufacturing facility in Fountain Inn, South Carolina, expanding its capacity to supply power inverters used in AI data center power infrastructure, grid applications, and energy storage. The site is intended to support rising demand tied to AI-driven load growth and power stability requirements.

The Fountain Inn plant is 167,000 square feet and is expected to create 275 new jobs. EPC Power said the facility nearly triples its production capacity. It’s the company’s second site in South Carolina and third overall.

The facility will manufacture EPC Power’s M and MRACK series power inverters. EPC Power describes these products as built for grid and storage applications as well as AI data center environments, using its proprietary Agile Grid Forming technology.

Upon reaching full production capacity later this month, EPC Power said the Fountain Inn facility will add 27 GW of annual capacity, with the ability to scale to 40 GW annually. Those are very large manufacturing figures, and for data center operators they translate into a straightforward practical benefit: more domestic supply of a component class that can become a gating item when power infrastructure lead times get tight.

Jim Fusaro, CEO of EPC Power, tied the expansion directly to AI-driven infrastructure investment: “By tripling our capacity, we’re giving data center and utility operators access to more critical components domestically, which de-risks their expansion plans and strengthens supply chain resilience.”

EPC Power said it provides power conversion systems for mission-critical applications including data centers, utility-scale energy storage, and microgrids.
