Texas note: Since August 3, 2026, ERCOT has paused approvals to energize new datacenter and crypto-mining loads of 75 MW or more until a verification audit and a community impact review are complete; both reports are due to the Public Utility Commission of Texas by December 10, 2026. ERCOT speed-to-power scores here were set before the pause and do not reflect it. ERCOT board update.
