EPC Power, a US-based manufacturer of grid-forming power converters, and ON.energy, a developer of power systems for grid-safe data centers, have announced a partnership to address hyperscale AI infrastructure needs. EPC Power will provide power converters to support the ON.energy AI UPS platform, a medium-voltage uninterruptible power supply (UPS) specifically designed to operate as a dynamic layer between the power grid and high-density compute environments.
According to ON.energy, integrating EPC Power’s silicon-carbide power converters adds grid-forming and blackstart capabilities to its AI UPS platform. The AI UPS system is engineered for hyperscale data center applications, delivering backup power and maintaining power quality for demanding AI workloads. The system absorbs rapid load fluctuations related to AI compute, supporting voltage and frequency ride-through that accelerate grid interconnection.
The AI UPS platform integrates EPC Power’s hardware and reportedly scales from megawatt to gigawatt deployments, supporting up to eight-hour runtimes. ON.energy claims this configuration is suitable for both grid-connected and off-grid environments, providing protection against fast transient loads while maintaining stable operation during significant power events.
Ricardo de Azevedo, Co-Founder and CTO of ON.energy, stated, “EPC builds in America and builds for performance. Their silicon-carbide M power converters add grid-forming and blackstart capability with industry-leading response, enhancing how ON.energy’s AI UPS platform manages fast AI ramping and dynamic load fluctuations. Together, we’re setting a new benchmark for grid-safe power at hyperscale.”
Jim Fusaro, CEO of EPC Power, noted technical challenges in the market, saying, “AI is fueling rapid data center growth, creating massive power challenges. Traditional systems can’t keep up with dynamic, high-density AI workloads. Digital power infrastructure is the solution, delivering reliable, secure, and adaptive power that responds in real time to changing demands with or without active grid integration.”
The companies report that this partnership will allow data centers to evolve their UPS infrastructure for grid-interactive operation and potential revenue-generation, in addition to providing essential backup and resiliency for critical loads.
