Texans are being asked again to conserve electricity.
The ERCOT electric grid expects record usage this week while more power plants are offline than usual for this time of year for repairs.
ERCOT spokesman Warren Lasher did not have the locations of the plants, or the specific reasons for what he described as “unplanned”, “unexpected”, and “unscheduled” shutdowns.
As of Monday afternoon, Lasher said the possibility of rolling blackouts was “unlikely”.
Lasher would not comment when asked if power plants going down were because generators were attempting to manipulate the system. Lasher said that kind of investigation would be up to an outside company hired by ERCOT as an “independent market monitor”.

News release from ERCOT:
The Electric Reliability Council of Texas (ERCOT) 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,” said ERCOT Vice President of Grid Planning and Operations Woody Rickerson. “This is unusual for this early in the summer season.”
According to generation owners, the number of outages should decrease throughout the week.
Wind output for today is expected to be 3,500 to 6,000 MW between 3 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 and 5 p.m.
Please take these simple actions to help reduce electric use:
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.
