HOUSTON -- Unseasonably hot temperatures forced power utilities around Texas to conduct rolling blackouts for several hours Monday.
As temperatures climbed into the upper 90s and above 100 for another day, the Electric Reliability Council of Texas, which runs Texas' electricity grid, declared an emergency situation. It ordered the blackouts because of the lack of electricity around the state.
By early Monday evening, ERCOT said the blackouts had ended and operations returned to normal. ERCOT said it declared the emergency because there was not enough generating capacity in the region to serve the public's electricity demand.
The energy shortage was compounded by plants undergoing planned
outages for maintenance.
The rollouts were limited to the ERCOT grid, which provides electricity to about 80 percent of Texas.
