EPC Power opened a new 167,000-square-foot (15,515-square-meter) manufacturing facility in Fountain Inn, South Carolina, significantly expanding its U.S. production capacity for power conversion systems used in AI data centers, utility-scale energy storage, and grid infrastructure. The new plant nearly triples the company’s manufacturing capacity and will produce its M and MRACK series power inverters, creating 275 new jobs. The facility represents EPC Power’s second location in South Carolina and third manufacturing site overall.
The company said the new factory will begin full production later this month with an initial manufacturing capacity of 27 GW annually and the ability to scale rapidly to 40 GW per year. EPC Power’s inverters incorporate its Agile Grid Forming™ technology, which is designed to help stabilize electrical systems supporting AI data centers where highly dynamic GPU workloads can produce rapid fluctuations in power demand. The systems are also intended for battery energy storage systems (BESS), microgrids, and utility-scale grid applications.
The expansion reflects accelerating investment in AI infrastructure and the growing need for domestically manufactured electrical equipment supporting high-density computing. EPC Power cited industry forecasts projecting nearly 100 GW of new global data center capacity by 2030, driving demand for power conversion equipment capable of improving grid stability while supporting large-scale AI deployments. The company said all of its inverters are manufactured in the United States.
• New manufacturing facility: 167,000 square feet (15,515 square meters)
• Location: Fountain Inn, South Carolina
• Annual inverter production capacity: 27 GW initially, scalable to 40 GW
• Creates 275 new manufacturing jobs
• Produces M and MRACK series power inverters
• Targets AI data centers, battery energy storage, microgrids, and utility-scale power systems
• Uses Agile Grid Forming™ technology to manage rapidly changing AI power loads
• EPC Power now operates three U.S. manufacturing facilities
“Our expansion in South Carolina is a direct response to the AI infrastructure investment and power demands we’re seeing worldwide. 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,” said Jim Fusaro, CEO of EPC Power.
🌐 Analysis
Power infrastructure is rapidly becoming one of the primary constraints on AI data center deployment. While GPUs, networking, and cooling receive much of the attention, high-capacity power conversion equipment—including inverters, switchgear, transformers, UPS systems, and battery storage—is emerging as a critical bottleneck as hyperscalers pursue multi-gigawatt AI campuses.
EPC Power’s expansion reflects a broader industry trend toward domestic manufacturing of critical electrical infrastructure. As AI campuses increasingly integrate battery storage, renewable energy, and grid-support capabilities, advanced grid-forming inverter technology is becoming an important element for maintaining power quality and resilience across increasingly dynamic electrical loads.
