The Electric Reliability Council of Texas, Inc. (ERCOT), system operator for the state's bulk transmission grid, initiated Energy Emergency Alert Level 1 at 2:40 p.m. Tuesday when responsive reserves dropped below 2,300 megawatts (MW). Capacity is expected to be tight over the peak today, and ERCOT operators are closely monitoring the situation.
"We are requesting that consumers and businesses reduce their electricity use during peak electricity hours from 3 to 7 p.m. today, particularly between 4 and 5 p.m. when we expect to hit another peak demand record," said Kent Saathoff, vice president of system planning and operations. "We do not know at this time if additional emergency steps will be needed."
Forecast for peak demand today is 67,084 MW, exceeding yesterday's new all-time record of 66,867 MW. Prior to this year, the record was 65,776 MW (Aug. 23, 2010).
