Peak Energy Demand Days are a few days each summer, and sometimes during the winter, when demand for electricity is highest. Conserve energy every day, and especially on peak energy demand days. Demand is typically at its highest in the summer between 3 p.m. and 8 p.m. on very hot days. Peak energy demand during the winter months occurs during the morning hours on cold days, but can be throughout the day when cold weather is extreme.
During extreme weather, pay attention to messaging from Electric Reliability Council of Texas (ERCOT), in the event they request reductions in electricity demand during certain hours. Download ERCOT's mobile app and follow ERCOT on X (formerly Twitter) @ERCOT_ISO to track electricity demand.
What steps can you take to conserve energy on Peak Energy Demand Days during the summer?
- Set thermostats 2° to 3° higher from 3 p.m. to 8 p.m. Set programmable thermostats to higher temperatures when no one is home.
- If home, use fans to feel 4° to 6° cooler. Set ceiling fans to run counter-clockwise for cooling.
- Set pool pumps to run early morning or overnight & shut off from 3 p.m. to 8 p.m.
- Turn off and unplug non-essential lights and appliances.
- Avoid using large appliances (i.e. ovens, washing machines, clothes dryers, etc.), especially during peak demand hours or the hours specified in a conservation appeal.
- Businesses should minimize the use of electric lighting and electricity-consuming equipment as much as possible.
- Large consumers of electricity should consider shutting down or reducing non-essential production processes.
- Review the energy-saving tips for air conditioning, refrigerator & freezer, washer, dryer, dishwasher, electronics, and lighting.
