Powering AI is an architecture problem
Moving power protection up the voltage stack, outside the building, and into the power path doesn't just solve outages; it changes density, permitting timelines and backup power economics.

On July 22, 2026, a transmission line fault in Ashburn, Virginia—the heart of the world's largest data center cluster—knocked
more than 3 gigawatts of load
off the grid in seconds. And it wasn't the first time. Two years earlier, a single failed surge arrester dropped
roughly 60 Virginia facilities and 1,500 megawatts
at once. No one could anticipate so much uniform load responding to grid faults the same way, at the same time.
The AI power debate is mostly about generation: more turbines, more solar, more transmission. The grid needs more electrons. But the outages in Virginia weren't supply failures; they were architecture failures. And a giant wave of interconnections is arriving on that same architecture, putting grid reliability at risk. It's a problem nobody wants to own.
Asking more from the grid
The grid was built around predictable loads: steel mills, refineries, and houses at dinnertime. Different load sizes, same process—drawing power smoothly, misbehaving occasionally, and recovering gracefully.
But AI data centers don't behave that way.
An AI campus can swing 70% of its load in milliseconds during a training run, then trip offline just as fast at the first sign of trouble upstream to protect billions in compute. Each is rational alone. Together, at gigawatt scale, they're a problem the grid has never solved—and the next wave of data center campuses is planned at exactly that scale.
Where the old stack breaks
The standard data center power stack hasn't changed in decades. Medium-voltage power arrives, transformers step it down, low-voltage uninterruptible power supply (UPS) units condition it, and it r
