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.”
“As LCLs increase on the ERCOT System, similar events would be expected to increase in magnitude and frequency, leading to frequency instability and other reliability problems absent frequency and voltage ride-through requirements,” the Texas PUC rules state.
