Grid manager says power supply better in South, ends warning

JACKSON, Miss. — A regional electricity grid manager says electric system conditions have improved and customers in most of Arkansas, Louisiana, Mississippi and a slice of eastern Texas no longer need to reduce usage.

Mississippi’s Cooperative Energy relayed the news Saturday evening from the Midcontinent Independent System Operator. The entity, known as MISO (MEYE’ soh) dispatches power to customers in all or part of 15 states and the Canadian province of Manitoba.

MISO had said earlier that some power plants were down, while high temperatures were driving air conditioner use.

If supply hadn’t demand, utilities including Entergy Corp., Cleco Corp. and cooperatives could have resorted to rolling blackouts.
