Monday, July 11, was a busy day for CPS Energy customers in San Antonio as the state’s Electric Reliability Council of Texas conservation period began. The state’s electricity grid operator is bracing for increased demand if temperatures rise above 100 degrees, which prompted the alert to go out to phone users.

From 2 to 8 pm, CPS Energy sent out an alert with links to their website, which had information on how to save energy.. “Proposed reserve capacity deficiency with no market solution,” ERCOT wrote in a notification Monday morning, which many are reporting as a risk of rolling blackouts.

Rudy Garza, interim CEO of CPS Energy, stated that the company’s infrastructure is stable and that the city of San Antonio will have enough electricity, although he urged residents to save energy wherever possible.

The following are a few pointers:


Between 2 and 8 p.m., raise the thermostat 2 to 3 degrees.

Turn increase the temperature on your thermostats when you’re away from home. The ideal temperature for conserving energy is between 78 and 80 degrees.

Ovens and washing machines should be avoided during peak hours.

4 to 6 degrees colder is possible with fans. It’s important to keep in mind that fans work by pushing air across the body of the person being cooled. There is no need to turn them on in unused rooms.


Buildings that are not in use will have their lights turned off and their temperatures set to 78 degrees, according to City Manager Eric Walsh. For those who don’t have a fan or air conditioning, 55 cooling centers are available in the city.

For the sake of energy conservation, Garza claims that CPS Energy has enough power to feed some of it into the ERCOT system.
