The Electric Reliability Council of Texas Inc., system operator for the state’s bulk transmission grid, is asking consumers and businesses to continue their energy conservation efforts.
Tuesday afternoon, a call for conservation was made between peak hours of 3-7 p.m.
“We are asking Texas residents and businesses to reduce their electricity use until 7 p.m.,” said Kent Saathoff, vice president of system planning and operations, in a press release Tuesday afternoon. “We don’t expect to need additional steps in the emergency procedures today unless we lose a significant amount of generation over the peak period.”
Peak electricity demand was forecast to be more than 67,700 MW Tuesday. One megawatt powers about 200 average homes in Texas during summer conditions.
“Until we get a break in this extreme heat and record drought, we appreciate consumers and businesses conserving electricity as they are able, especially between 3 and 7 p.m.,” Saathoff said. “We also appreciate all the state agencies, school districts, businesses and residents who have taken steps to get the word out about the importance of conservation during these extreme weather conditions.”
Consumers can help by shutting off unnecessary lights and electrical appliances between 3 and 7 p.m. and delaying laundry and other activities requiring electricity-consuming appliances until later in the evening. Other conservation tips from the Public Utility Commission’s “Powerful Advice” include:
• Turn off all unnecessary lights, appliances and electronic equipment.
• When at home, close blinds and drapes that get direct sun, set air conditioning thermostats to 78 degrees or higher and use fans in occupied rooms to feel cooler.
• When away from home, set air conditioning thermostats to 85 degrees and turn all fans off before you leave. Block the sun by closing blinds or drapes on windows that will get direct sun.
• Do not use your dishwasher, laundry equipment, hair dryers, coffee makers, or other home appliances during the peak hours of 3 to 7 p.m.
• Avoid opening refrigerators or freezers more than necessary.
• Use microwaves for cooking instead of an electric range or oven.
• Set your pool pump to run in the early morning or evening instead of the afternoon.
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.
Emergency Procedures Background
The Energy Emergency Alert procedures are a progressive series of steps that allow ERCOT to bring on power from other grids if available, beginning with a Power Watch (Energy Emergency Alert Level 1).
If the situation does not improve, ERCOT escalates to a Power Warning (Energy Emergency Alert Level 2), allowing operators to drop large commercial/industrial load resources under contract to be interrupted during an emergency.
If the capacity shortage is not relieved by the contract demand response, ERCOT escalates to a Power Emergency (Energy Emergency Alert Level 3) and will instruct utilities to reduce demand on the grid by conducting temporary outages at the local distribution level. These controlled temporary interruptions of electrical service – or rotating outages – typically last 15-45 minutes before being rotated to a different neighborhood.
Consumers should contact the utility company/ transmission provider listed on their electric bill for information about power outages at their homes or business, or about rotating outage procedures for their area.
