San Antonio, Texas – (April 13, 2021) – CPS Energy residential and business customers along with Texas residents in the Electric Reliability Council of Texas (ERCOT) region are encouraged to reduce their electricity use as much as possible to help prevent electricity emergencies or the need for rotating outages implemented to protect the electric grid.

ERCOT requests energy conservation due to a combination of high generation outages and higher than expected demand.

To conserve energy at home, customers should:

  • Set thermostats 2 to 3 degrees higher, from now until 7:00 p.m.; set programmable thermostats to higher temperatures when no one is home. The optimum energy-saving temperature is 78 degrees.
  • Avoid using large appliances (i.e. ovens, washing machines, etc.), especially during peak demand hours.
  • Use fans to feel 4 to 6 degrees cooler.
  • Set pool pumps to run early morning or overnight; shutoff from 4:00-6:00 p.m.
  • Turn off and unplug non-essential lights and appliances.

To also increase energy effectiveness at work, business customers should:

  • Minimize the use of non-emergency lighting and electricity-consuming equipment as much as possible.
  • Consider shutting down or reducing non-essential production processes.
