Energy conservation can help save energy and money throughout year. When consumers respond to ERCOT requests to reduce energy demand during certain hours, it helps grid reliability.
As the grid operator for most of Texas, ERCOT works every day to make sure there is enough electricity available for consumer needs. Sometimes the demand for electricity may be very close to the amount of generation available, either because consumers are using a lot of electricity or some power plants are not able to provide enough power. On those days, ERCOT may issue a conservation alert. Peak demand during the summer occurs between 3 and 7 p.m on very hot days, and winter peaks occur during the early morning (5-9 a.m.) and early evening (4-9 p.m.) on very cold days.
