At around 6 p.m. on Monday, February 15th, Southwest Power Pool, the transmission grid supplying Lubbock Power & Light's electric grid, returned to Energy Emergency Level 2.
Lubbock Power & Light, South Plains Electric Co-op, and Lyntegar Electric Cooperative all operate in the Southwest Power Pool. They will have to implement rolling blackouts some point Monday afternoon due to record electrical demand.
Just before 9am Saturday, ERCOT's reserve electrical capacity was just 89 megawatts. ERCOT electricity usage may set a winter record this weekend due to a 5-day long stretch of extremely low temps across the state.
