One Line Failure Exposed a New AI Data Center Risk: How to Avoid Grid Instability

A transmission line outage near Washington showed how sharply large loads can hit the grid: more than 3 GW of data centers switched to backup power almost at once.

In PJM, that caused a voltage surge and visible flickering across the region, though it did not become a blackout.

The takeaway is clear: data centers must not only consume power, but also ride through outages without mass shutdowns.

That means smoother load transfers, battery storage, and systems that hide peak swings from the grid.

As AI expands, such incidents will become more frequent, and the cost of infrastructure errors will rise.

Do you think the industry is ready for this scenario?
