The customers of the utility subsidiaries of Entergy Corporation saved approximately $1.3 billion on their electric bills from 2014 to 2018 due largely to Entergy’s membership in the Midcontinent Independent System Operator (MISO) regional transmission organization, Entergy said Monday.

“When we proposed joining MISO, we told our customers this would be a good business decision that would benefit them each month,” Rod West, utility group president, said. “We believe we have made good on that promise. Our membership in MISO has been a highly effective tool in helping our customers keep more of their hard-earned money in their pockets. It has also helped us control costs and keep our rates among the lowest in the nation. Since joining MISO five years ago, Entergy customers have saved an average of $261 million per year. These are real savings for our customers.”

Entergy estimates that Entergy Arkansas customers saved $223 million, Entergy Louisiana customers saved $561 million, Entergy Mississippi customers saved $207 million, Entergy New Orleans customers saved $118 million and Entergy Texas customers saved $198 million between 2014 and 2018, for a total of approximately $1.3 billion.

“The estimated $1.3 billion in savings realized between 2014 and 2018 is largely because, through participation in MISO, Entergy is part of a large pool of generating facilities that stretch across the vast MISO footprint,” Entergy said in a press release. “By sharing in that large pool, Entergy can maintain reliability with less power generation capacity than if it were on its own – and pass the resulting savings along to customers. In addition, because MISO dispatches a large pool of generation to serve the needs of all customers in its footprint, the dispatch is more efficient, resulting in a lower delivered cost of energy and long-term benefits for customers.”
