Update: At 6:30 p.m., SLEMCO said they had been contacted by grid managers who said that generation load is at a critical point. In order to avoid rolling blackouts, SLEMCO is asking that all customers conserve electric use through the night, but particularly through 12:30 a.m. Wednesday morning.
SLEMCO was notified at 9:40 a.m. Tuesday that they were able to discontinue the rolling blackouts. If conditions change, SLEMCO says they will update customers through local and social media.
Initially Slemco said they were instructed by MISO to begin rolling blackouts immediately (Tuesday, February 16). They began rotating temporary power interruptions in 20 minute intervals for SLEMCO customers in western Lafayette Parish and North Vermilion Parish where excessive demand has overloaded the regional power grid.
