ERCOT Breaks Record for Electricity Demand Again

The Electric Reliability Council of Texas, Inc. (ERCOT), the electric grid operator for most of the state, set a new electricity demand record again today with 63,830 megawatts (MW) between 4 and 5 p.m. today. 

The new peak demand exceeds last week’s record of 63,594 MW (Aug. 4) by 236 MW, and last year’s record by 430 MW.  Prior to last week, the all-time peak demand record was 63,400 MW, recorded on July 13, 2009. 

Wind output averaged approximately 1,200 MW during the peak hour.  ERCOT currently has 9,317 MW of installed wind capacity, the highest of any state in the country. 

According to ERCOT’s annual summer assessment, the region has adequate generation to cover an expected summer peak demand over 64,000 MW and still maintain a 21 percent cushion of reserves to cover unexpected major outages. 

One megawatt is roughly enough electricity to power 500 average homes under normal conditions in Texas, or about 200 homes during hot weather when air conditioners are running for longer periods of time. 

The new peak is an integrated hourly average of electricity load between 4 and 5 p.m. based on preliminary calculations.  It is not final until completion of the market’s financial settlement process six months after the operating day.
