EPC Power Corp. (EPC Power), a leading US-based manufacturer of advanced grid-forming power conversion systems, has deployed its advanced M System, featuring Agile Grid Forming technology.

Engineered specifically to address the volatile power demands of artificial intelligence (AI) workloads, this solution is more than just an inverter. It’s a digital power processor that provides a foundation for maintaining uptime in the world’s most demanding high-density compute facilities.

When milliseconds matter: Understanding AI power instability

As AI training clusters scale, they introduce electrical challenges that traditional power infrastructure isn’t designed to handle. Unlike standard data center loads, AI GPU servers generate highly volatile power profiles, swinging consumption levels within milliseconds.

These rapid fluctuations create instability that propagates through a facility’s distribution system. For data centers utilizing onsite generation, such as gas turbines or reciprocating engines, these shifts introduce harmful mechanical stresses and power quality degradation. Without mitigation, these fluctuations can shorten equipment lifespans and lead to costly systemwide instability.

Built for AI power volatility

Traditional solutions, including flywheel, UPS or other frequency-stabilizing technologies, often lack the response or flexibility required to mitigate AI-driven volatility. To address this gap, EPC Power’s Agile Grid Forming technology is a more responsive evolution of these systems, designed to bridge the gap between short-duration buffering and long-term energy storage.

"AI workloads require a level of power quality and stability far beyond what traditional infrastructure can provide," said Jim Fusaro, CEO of EPC Power.

"By utilizing our US-manufactured M series inverters with Agile Grid Forming technology, we deliver a solution that reacts to deviations, while providing precise load smoothing that protects the data center's internal compute health and the stability of the surrounding utility grid."

Core capabilities of the M System with Agile Grid Forming

EPC Power’s approach delivers a resilient, intelligent foundation for AI infrastructure through several key innovations:

  • Proactive load smoothing: Unlike traditional grid-forming systems that depend on voltage and frequency deviations to trigger a response, EPC’s technology offsets fluctuations at the point of interconnection more comprehensively.
  • Millisecond response times: The system responds within milliseconds to deviations caused by rapid load changes, neutralizing disturbances before they impact sensitive hardware.
  • Versatile interconnection: Designed to be effective whether a site is powered by onsite generators or connected to a utility grid.
  • Bridging on-site generation and grid power: To accelerate speed-to-market, many data centers now launch with on-site generation before transitioning to a utility grid. EPC’s technology is effective in both scenarios, smoothing AI load ramps whether the facility is self-generating or grid-connected.
  • Scalable BESS integration: The M series platform allows Battery Energy Storage Systems (BESS) to scale from 3MW blocks to 100MW+ systems, providing the high-capacity buffering required by modern AI campuses.

Enabling the future of AI infrastructure

As AI growth pushes power systems to new limits, EPC Power is providing the disturbance ride-through capabilities necessary to enable the next generation of digital infrastructure. As the only large-scale US manufacturer of these products, EPC Power ensures a secure and reliable supply chain while helping operators meet aggressive construction timelines and strict utility requirements.
