ERCOT, the operator of the state's electric grid, issued a voluntary notice for 3-8 p.m. on Thursday "due to extreme temperatures, forecasted high demand, and lower reserves due to low wind generation," it said on social media.

"Texans are asked to voluntarily reduce electric use, if safe to do so," the message added.
ERCOT said that's it not in emergency operations, but the request does ask for all government agencies, including city and county offices, to implement any programs to reduce energy use at their facilities.

- Raise your thermostat by a degree or two, if it's safe to do so
- Avoid using large appliances such as a washer or dryer
- Turn off and unplug non-essential lights and appliances
- Set pool pumps to run early morning or overnight. Shut them off during peak hours
- For commercial businesses, turn off any lights and office equipment, or use sleep mode, when not in use. Also turn off air-conditioning outside of business hours
- Use ceiling fans and portable fans to circulate the cool air
- Close blinds and/or curtains on windows that receive direct sunlight
- Shade A/C units or condensers located outdoors, if possible
Roughly two weeks ago, Reliant Energy asked Texans to conserve after days of triple-digit temperatures. So far, ERCOT had only issued what it called Weather Watches.
A Weather Watch is supposed to provide the public with early notification, and at least three to five days in advance, when higher demand is forecasted. A message from ERCOT's Texas Advisory and Notification System (TXANS) says a Weather Watch is in place through Friday, Aug. 18.
ABC13 reported in May that the Public Utility Commission said the odds of the grid failing this summer are low, but it's possible it can happen.
