Inverter producer EPC Power is expanding its operations by opening a 167,000-square-foot factory in Fountain Inn, South Carolina. This expansion nearly triples the company's production capacity. The new facility will manufacture M and MRACK series power inverters intended for solar, grid, storage applications, and AI data centers. EPC Power anticipates reaching full production capacity by the end of July, adding 27 gigawatts of annual capacity to the market. Furthermore, the facility is projected to create 275 new jobs. The company stated that this increased domestic manufacturing provides greater access to critical power conversion components for data center and utility operators, aiming to enhance supply chain resilience.

The narrative centers on leveraging domestic manufacturing capacity to de-risk the supply chain for energy infrastructure, specifically targeting the high-growth AI data center market. The shift in focus is from purely incremental growth to strategic national supply assurance. The implication is that securing critical technology components geographically is framed as a matter of geopolitical and economic resilience rather than mere operational optimization. The pattern observed is an appeal to foundational stability—the idea that decentralized, domestic production inherently strengthens the wider system against external uncertainties. The assumption underlying this framing is that physical proximity to end-users (data centers) translates directly into systemic risk mitigation for operators. A critical question remains: how much does this localized capacity actually change the distribution dynamics of these components, and who ultimately bears the cost or responsibility associated with this newly strengthened resilience? What alternative supply chain models exist that do not rely on geographic concentration to achieve similar resilience?
