ERCOT and AEP Texas request help from Texans to conserve power this week

A significant number of forced generation outages has resulted in tight grid conditions.

AUSTIN, Texas — The Electric Reliability Council of Texas is asking Texans to reduce electric use as much as possible today through Friday, June 18. A significant number of forced generation outages combined with potential record electric use for the month of June has resulted in tight grid conditions.

Generator owners have reported approximately 11,000 MW of generation is on forced outage for repairs; of that, approximately 8,000 MW is thermal and the rest is intermittent resources. According to the summer "Seasonal Assessment of Resource Adequacy," a typical range of thermal generation outages on hot summer days is around 3,600 MW. One MW typically powers around 200 homes on a summer day.

“We will be conducting a thorough analysis with generation owners to determine why so many units are out of service,” ERCOT Vice President of Grid Planning and Operations Woody Rickerson said in a press release. “This is unusual for this early in the summer season.”

According to generator owners, the number of outages should decrease throughout the week.

Wind output for Monday is expected to be 3,500 to 6,000 MW between 3 p.m. and 9 p.m. This is roughly 1,500 MW lower than what is typically available for peak conditions. Wind output is expected to increase as the week goes on.

Today’s peak load forecast may exceed 73,000 MW. The peak demand record for June is 69,123 MW set on June 27, 2018, between 4 p.m. and 5 p.m.

ERCOT and AEP are offering the following tips:

  • Set your thermostat to 78 degrees or higher – every degree of cooling increases your energy use by six to eight percent.
  • Turn off lights and pool pumps and avoid using large appliances like ovens, washing machines and dryers.
  • If you don’t need something – we are asking you to turn it off and unplug it if possible.
  • Visit the Power to Save website or your electric provider for more ways to conserve.
