ERCOT issued the rolling blackout order early Monday morning after winter storms covered the state in ice and snow and left life-threatening low temperatures in its wake. it continues to urge all Texans to limit and reduce their electric use as much as possible.
ERCOT described the rotating outages as a “last resort to preserve the reliability of the electric system as a whole,” adding that utility transmission companies are tasked with determining how to reduce demand on the system. Rotating outages are controlled, temporary interruptions of electrical service that rotate through different parts of the electric grid.
Some Tips to reduce power use include, turning off or unplugging non-essential equipment such as small appliances, and trying to avoid using large appliances during peak hours like the mornings and evenings. turning thermostats to 68 degrees or lower, closing blind or shades to reduce the amount of heat that leaves homes.
