AUSTIN (KXAN) — For the second time in three days, the Electric Reliability Council of Texas (ERCOT) is asking Texans to voluntarily conserve power as grid conditions tighten during intense summer heat. It’s a voluntary request from the agency, which expires at 9 p.m. Wednesday.

How do you conserve power? For that, we turned to Power to Save Texas.

Air conditioning

  • Turn your AC up a few degrees. Power to Save Texas said every degree above 78° can save you up to 8% on your energy bill
  • Set you AC to 80° when you’re gone for more than 4 hours
  • Invest in a smart thermostat that can be controlled even while you’re away
  • Use fans. Power to Save Texas says they can make a room feel 4-6° cooler
  • Keep the sun from shining into your home using blinds and curtains
  • Try not to use the vent fans above your stove and in your bathroom. They pull in hot air, Power to Save Texas says
  • If you do lose power, and therefore air conditioning, here are some tips for staying comfortable


  • Think about when you use your appliances which can use energy

  • Keep your refrigerator and freezer full, even if just full of bottles of water, Power to Save says. A full fridge uses less energy
  • Use the air-dry setting on your dishwasher. The heat-dry uses more energy and also heats your home
  • Unplug TVs and other electronics when you leave the room


  • LED lightbulbs can use up to 90% less energy than old incandescent bulbs, Power to Save says. Those bulbs can save you money
  • Keep your light bulbs clean and free of dust so they are more efficient
