CPS Energy is asking residents of the San Antonio area to reduce their demand for electricity for the afternoon of 23 august with the aim of reducing the likelihood of brownouts or blackouts.

With temperatures forecast for the upper 90s on Monday and heat indexes appearing to be over 100 degrees, energy demand is expected to be high.

Days with high energy demand occur a few days each summer, and sometimes during the winter, when electricity demand is greatest. Demand is generally at its highest in summer between 2 p.m. and 7 p.m.. on very hot days.

In extreme weather conditions, pay attention to the messages from the Electric Reliability Council of Texas (ERCOT), in the event of a request to reduce the demand for electricity at certain times. Download the ERCOT mobile app and follow ERCOT on Twitter @ERCOT_ISO to monitor the demand for electricity.

How to save on days of high energy demand:

  1. Set your thermostat to 78 degrees or higher. Increase it a bit more if you leave the house.

  2. Remember the “20 degree rule” that air conditioners are designed to cool your home to about 15 to 20 degrees cooler than the outside temperature. If the difference between the outside temperature and your thermostat setting is more than 20 degrees, then your air conditioner will run nonstop!

  3. Maintain your air conditioner with seasonal tune-ups and change filters monthly during the hot summer months.

  4. Use fans and point them in your direction to feel 4-6 degrees cooler. Set ceiling fans to run counterclockwise in summer.

  5. Lower shades and shades when exposed to direct sunlight.

  6. Avoid using large appliances like ovens and dryers. Cook outside on a grill and dry your clothes when you can.

  7. Turn off lights and unplug televisions, game consoles, and other equipment when you leave a room. Use multiple sockets to make this quick and easy. All electrical devices use energy when connected to an outlet and can generate heat when they are turned off, but still plugged in.

  8. Limit your use of fans above your stove and in your bathroom, as they suck in warm outside air, making your air conditioner more difficult.

  9. Refrigerator and Freezer Tips: Keep your refrigerator and freezer full because a full refrigerator uses less energy. Set the refrigerator temperature between 37 ° and 40 ° degrees Fahrenheit. Set the freezer between 0 ° and 5 °. Make sure the gasket around the door is airtight and keep the refrigerator coils clean of lint and dust. Do not keep a refrigerator in an unconditioned space as it will have to work harder to stay cool.

  10. Replace traditional incandescent bulbs which use a lot of energy to produce light, generate heat and are no longer manufactured. Compact Fluorescent Lights (CFLs), Halogen Incandescent Bulbs, and Light Emitting Diodes (LEDs) may cost more upfront than traditional incandescent bulbs, but they save you money over the course of their life of life because they consume less energy. CFLs and LEDs are ideal for outdoor lighting fixtures that sometimes stay on for a long time and can be exposed to the elements.

Save energy every day, and especially on days of high energy demand.
