The electricity system serving much of Texas is distinctive, but no single organization controls every aspect of the state’s power supply. ERCOT operates the grid and wholesale market within its region, while utilities, generators and regulators have different responsibilities.
How the system works
Electricity demand varies with weather, time of day and economic activity. Power plants, transmission lines, fuel supplies and customer usage all influence system reliability.
What to verify
A grid conservation request is different from a mandatory rotating outage. Consumers should follow current instructions from their electricity provider and official emergency managers rather than assume all advisories mean service will be interrupted.
Official resources
Visit ERCOT for grid conditions and market information and the Public Utility Commission of Texas for regulatory resources.
What readers can do next
Households can prepare for outages by keeping emergency supplies, identifying medical-device backup requirements and following safety guidance about generators and carbon monoxide.
