AUSTIN, Texas – UPDATE 8:40 p.m.: CPS Energy said it would return to its Yellow Alert after ERCOT’s Energy Emergency Alert Level 2 has been discontinued. ERCOT said Wednesday night that it would be “returning to normal operations. Reducing electric use is still encouraged.”
ERCOT is urging Texans to conserve energy on Wednesday evening, issuing an Energy Emergency Alert Level 2.
“Please reduce electric use. If you have medical needs, contact your local utility, and have a backup plan,” ERCOT said Wednesday night.
Texans should conserve their electricity between 6 p.m. and 9 p.m., ERCOT said in a press release. Government entities and businesses are also urged to reduce their energy use.
“At this time, there are no power outages associated with the ERCOT power grid. ERCOT will continue to monitor conditions and deploy all available tools as part of our reliability-first approach to operations. ERCOT continues to request Texans conserve electricity use,” officials said Wednesday night.
ERCOT said an Energy Emergency Alert Level 2 issued when operating reserves have dropped below 1,750 MWs and are not expected to recover within 30 minutes.
“Controlled outages have not been requested at this time, however, could become necessary if demand isn’t lowered or additional supply cannot be added from generators,” ERCOT said.
CPS Energy issued an Orange Alert and offered customers the following tips:
- Limit power usage
- Prepare for possible loss of power
- Prepare to implement your household plan for emergencies
- Be ready to initiate your plan for alternative operation of medical devices, if needed
- Turn off pool pumps
- Avoid charging electric vehicles (EV), or charge overnight
