EPC Power opens Fountain Inn manufacturing facility

EPC Power on July 15 opened a manufacturing facility in Fountain Inn that will create 275 new jobs and produce inverters that will support up to 40 gigawatts of annual capacity for an increasingly energy-thirsty society.

The power management solutions company says it is the only independent, American-owned manufacturer of utility-scale power conversion technology.

The 167,000-square-foot facility nearly triples its production capacity, enabling EPC Power to meet the rising demand for AI data center infrastructure and grid and energy stability, according to a news release.

The new site is the company’s second in South Carolina and third overall. It will produce EPC Power’s M and M-rack series power inverters, which are specifically built for grid and storage applications, as well as AI data center environments using proprietary Agile Grid Forming technology. The inverters are essential for managing unpredictable and fluctuating AI workload power demands and help keep data centers running reliably while reducing strain on the electric grid, according to the release. Upon reaching full production capacity later this month, the facility will immediately add 27 gigawatts of annual capacity and can be quickly scaled up to 40 gigawatts annually.

“Our expansion in South Carolina is a direct response to the AI infrastructure investment and power demands we’re seeing worldwide,” EPC Power CEO Jim Fusaro said in the release. “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.”

The new facility comes as the global data center industry faces unprecedented growth. According to JLL’s 2026 Global Data Center Market Outlook, nearly 100 gigawatts of new data center capacity is expected to be added by 2030, doubling global capacity. With a projected 14% CAGR for the data center market, energy innovations like EPC Power’s inverters are vital to alleviating grid constraints, according to the release. EPC Power is the only domestic manufacturer that produces all its inverters in the U.S. The South Carolina facility positions EPC Power to continue securing the U.S. data center supply chain, while reinforcing the state as a premier hub for technological innovation.
