Dive Brief:

The Texas Public Utility Commission on Thursday unanimously approved rules that will require large computational loads, like data centers and crypto-mining facilities, within the Electric Reliability Council of Texas footprint to stay stable and connected to the grid through disruptions.

Modern computational loads, Kenteel Engineering said in a June blog, are “engineered to protect extremely sensitive and expensive equipment,” and during a voltage dip are programmed to disconnect or enter momentary cessation.

However, this presents a reliability problem, Kenteel Engineering said, as when “several hundred — or several thousand — megawatts of computational load all detect the same sag and drop simultaneously, the grid experiences a sudden, large loss of demand.”
