MISO Membership Produces Millions in Savings for Entergy’s Louisiana Customers

05/04/2015

BATON ROUGE, La. -- The results are in, and customers of Entergy's Louisiana utilities are saving big thanks to the move to join MISO, a regional transmission organization.

Customers of Entergy's Louisiana utilities saved an estimated $120 million during the first year of membership in MISO, formally known as the Midcontinent Independent System Operator, Inc. Entergy's utilities joined MISO on Dec. 19, 2013, after a lengthy period of regulatory review.

MISO manages the commitment and dispatch of generation on the transmission grid, maintains reliability, plans new transmission facilities, and operates markets for the purchase and sale of electricity and related products.

The estimated $81 million in savings for Entergy Louisiana, LLC customers and the estimated $39 million saved by Entergy Gulf States Louisiana, L.L.C. customers were largely driven by the more efficient commitment and dispatch of power plants, resulting in access to lower cost generation through MISO's power market.

In addition, MISO has allowed Entergy's Louisiana utilities to reduce their required generation capacity reserves by 598 megawatts, producing additional long-term benefits and savings for its customers.

"Thanks to the foresight of the Louisiana Public Service Commission, we've been able to provide our customers with the wide range of benefits offered by membership in MISO, a membership from which they will benefit for years to come. Joining MISO is a great example of how we work to control customer costs and keep rates low so we can continue helping drive economic growth in Louisiana," said Phillip May, president and CEO of Entergy's Louisiana utilities.

Entergy's Louisiana utility companies provide electric service to more than one million customers through the operating companies Entergy Louisiana, LLC and Entergy Gulf States Louisiana, L.L.C. and natural gas service to nearly 93,000 customers in the greater Baton Rouge area through Entergy Gulf States Louisiana. With operations in southern, central and northeastern Louisiana, the companies are subsidiaries of Entergy Corporation.

Entergy Corporation is an integrated energy company engaged primarily in electric power production and retail distribution operations. Entergy owns and operates power plants with approximately 30,000 megawatts of electric generating capacity, including nearly 10,000 megawatts of nuclear power, making it one of the nation's leading nuclear generators. Entergy delivers electricity to 2.8 million utility customers in Arkansas, Louisiana, Mississippi and Texas. Entergy has annual revenues of more than $12 billion and approximately 13,000 employees.
