ERCOT Tightens Data Center Grid Standards Before Summer Peak

ERCOT is now requiring data centers and crypto mining facilities to prove they can withstand voltage disturbances without disconnecting before grid interconnection. The mandate follows recent test failures by several large facilities planning Texas connections. Operators must redesign power infrastructure — UPS, transfer switches, inverters — to meet grid fault ride-through standards historically applied only to generators. The tightened rules aim to prevent sudden load shedding events that could trigger cascading outages during peak summer demand.
