The move will help the state’s grid operator, Electric Reliability Council of Texas (ERCOT), ease worries that the mining will put extra stress during periods of high system demand. “Due to the anticipated interconnection of an increasing number of large flexible Loads in the ERCOT Region, ERCOT is establishing an interim, voluntary curtailment program that would allow these Loads to assist ERCOT in ensuring reliability during periods of high system demand,” ERCOT said in a statement.
