In the rolling industrial landscape of Upstate South Carolina, a new facility in Fountain Inn is quietly reshaping the backbone of America’s artificial intelligence infrastructure. EPC Power has opened a 167,000-square-foot manufacturing plant at 111 Southchase Boulevard, bringing advanced power-conversion technology production to Greenville County and strengthening a rapidly expanding regional ecosystem of electrical manufacturing.

The facility is expected to create 275 jobs and nearly triple the company’s manufacturing capacity. As EPC Power scales operations, the plant is projected to reach full production before July 2026, adding approximately 27 gigawatts of annual manufacturing capacity, with the potential to expand to 40 gigawatts annually [PR Newswire](https://www.prnewswire.com/news-releases/epc-power-expands-us-manufacturing-to-meet-surging-demand-for-ai-data-center-power-302825669.html?utm_source=chatgpt.com).

“This expansion in South Carolina is a direct response to the AI infrastructure investment and power demands we’re seeing worldwide,” said CEO Jim Fusaro, emphasizing the importance of domestic manufacturing in reducing supply chain risks and accelerating infrastructure deployment [PR Newswire](https://www.prnewswire.com/news-releases/epc-power-expands-us-manufacturing-to-meet-surging-demand-for-ai-data-center-power-302825669.html?utm_source=chatgpt.com).

Powering the AI Era

At the heart of EPC Power’s operation are industrial-scale inverters and power-conversion systems—critical components that manage the flow of electricity between direct current DC sources such as batteries and alternating current AC systems used by power grids and data centers. Unlike residential solar inverters, these systems are engineered for utility-scale applications, including battery storage, microgrids, renewable energy installations, and high-demand AI data centers.

The company’s systems go far beyond simple conversion. They provide voltage support, frequency regulation, power-factor correction, peak-load reduction, black-start capability, and harmonic cancellation. In some installations, they even replace traditional uninterruptible power supplies in mission-critical environments [epcpower\.com](https://www.epcpower.com/about/company).

The Fountain Inn facility will focus on EPC Power’s M System and M-RACK product lines—modular platforms designed to meet the unique electrical demands of modern AI computing environments [PR Newswire](https://www.prnewswire.com/news-releases/epc-power-expands-us-manufacturing-to-meet-surging-demand-for-ai-data-center-power-302825669.html?utm_source=chatgpt.com).

Stabilizing a Volatile Grid

AI data centers present a new challenge for the electrical grid. Unlike traditional facilities with predictable loads, AI clusters can shift power demand dramatically in fractions of a second as thousands of processors ramp up or down simultaneously. These rapid fluctuations—known as transient load swings—can destabilize voltage and frequency, placing stress on generators and grid infrastructure.

EPC Power addresses this challenge with its Agile Grid Forming technology, which integrates inverters with battery systems to respond instantly to changing conditions. Acting as a digital power processor, the system absorbs volatility, stabilizes the grid, and ensures uninterrupted operation. Built on a modular silicon-carbide architecture, it can be tailored to a wide range of data center configurations [epcpower\.com](https://www.epcpower.com/).

In practice, these systems function as an electrical buffer. Batteries release energy when demand spikes and absorb excess power when it drops, smoothing fluctuations and protecting both on-site generation and the broader grid.

Manufacturing at Scale

EPC Power’s commitment to domestic production is central to its strategy. The Fountain Inn plant assembles complex systems from power-electronic modules, semiconductor components, control boards, cooling systems, and protective equipment. Each unit undergoes rigorous testing and quality verification to ensure safe operation under extreme electrical loads.

The company operates manufacturing facilities in South Carolina and Poway, California, with additional engineering and support operations in North Carolina and Helsinki, Finland. Its systems are deployed in more than 60 countries, representing over 15 gigawatts of installed capacity worldwide [epcpower\.com](https://www.epcpower.com/about/company).

The plant’s 27-gigawatt annual capacity refers to the total rated output of the equipment it can produce—not the electricity it consumes—highlighting the scale at which EPC Power is positioning itself within the global energy infrastructure market.

A Growing Industrial Network

EPC Power’s expansion builds on its earlier investment in Greenville County. In 2022, the company committed $5 million and 150 jobs to establish its first East Coast manufacturing and engineering operation in the Mauldin-Simpsonville area, supported by state incentives and workforce development initiatives \([S\.C\. Governor](https://governor.sc.gov/news/2022-11/epc-power-establishing-operations-greenville-county?utm_source=chatgpt.com)\).

Since then, the company has more than doubled its production capacity, culminating in the Fountain Inn facility—a significant step toward high-volume manufacturing for AI and energy markets [epcpower\.com](https://www.epcpower.com/news/epc-power-names-jim-fusaro-as-ceo?utm_source=chatgpt.com).

The workforce reflects the technical complexity of the operation. Positions range from manufacturing technicians and production supervisors to quality engineers, test engineers, and supply chain specialists. Compensation spans hourly technical roles to six-figure engineering and management positions, underscoring the diversity and skill level required [Paylocity](https://recruiting.paylocity.com/recruiting/jobs/All/c1f3b7e2-3b9f-4552-ae5e-972d37009918/EPC-POWER-CORP?utm_source=chatgpt.com); [Indeed](https://www.indeed.com/q-epc-power-l-fountain-inn%2C-sc-jobs.html?utm_source=chatgpt.com).

Strengthening the Upstate Economy

The impact of the Fountain Inn facility extends beyond its workforce. The plant integrates into Greenville County’s established manufacturing base, drawing on regional expertise in automotive, electrical, and industrial production. It also creates opportunities for local educational institutions to expand training in power electronics, automation, and engineering technologies.

Unlike hyperscale data centers, which demand vast amounts of land, water, and electricity, EPC Power’s facility contributes to the AI economy through manufacturing rather than consumption. This distinction allows the region to participate in the growth of AI infrastructure while maintaining a balanced industrial footprint.

Local coverage from outlets such as the Upstate Business Journal highlights the facility’s role in expanding the region’s manufacturing capabilities and confirms its location at Southchase Boulevard [Upstate Business Journal](https://upstatebusinessjournal.com/business-news/epc-power-opens-fountain-inn-sc-manufacturing-facility/?utm_source=chatgpt.com).

A Regional Power Corridor

The addition of EPC Power’s facility reinforces a broader trend across the Southeast. From Virginia to Alabama, a network of manufacturers is emerging to support the electrical infrastructure required for AI and energy systems. Transformer factories, switchgear manufacturers, and new companies producing separators and insulators are forming a supply chain that is increasingly concentrated in this corridor.

Within this context, EPC Power fills a critical role. Its inverters and power-conversion systems connect and stabilize the components produced by these other manufacturers, enabling them to function as an integrated system. Together, these facilities are building a domestic supply chain capable of supporting the rapid expansion of AI data centers and modernized power grids.

A Strategic Link in the Chain

As demand for AI infrastructure accelerates, the importance of reliable, domestically produced electrical equipment continues to grow. EPC Power’s Fountain Inn facility represents more than a local economic development project—it is a strategic addition to a national effort to secure the energy systems that underpin the digital economy.

By anchoring advanced power-conversion manufacturing in Upstate South Carolina, EPC Power is helping to transform the region into a hub for next-generation energy technology. In doing so, it strengthens not only the local economy but also the broader network of manufacturers across the Southeast that are collectively powering the future of artificial intelligence.
