Texans can now receive text message alerts about potential power grid emergencies, giving residents a new way to stay informed when electricity supplies are strained.

The Electric Reliability Council of Texas (ERCOT) announced Tuesday that it has expanded its Texas Advisory and Notification System, known as TXANS, to include text message notifications for the first time.

The upgraded system will notify subscribers about severe weather that could affect the grid, requests to conserve electricity and emergency conditions that could lead to controlled power outages.
