“Hearing about the continuing surge of wind generation in the Electric Reliability Council of Texas, a state regulator on Tuesday expressed “concern” about too many out-of-market actions to ensure local reliability threatened by a sudden drop in wind output. Early in the ERCOT Board of Directors meeting, Bill Magness, ERCOT president and CEO, pointed out that wind generation hit a new record of 50% of load early on March 23, with about 1,500 MW of wind curtailed. If that wind generation had not been curtailed, wind’s share of all load would equal about 55%.”
