Utility Files Application with Public Utility Commission to Join MISO

Beaumont, Texas—Entergy Texas, Inc. today took the next step toward fulfilling its plan for meeting the future power needs of its customers, a plan projected to provide those customers with millions of dollars in net cost savings.

The company filed a formal change of control request with the Public Utility Commission of Texas (PUCT), a key step in its plan to join a regional transmission organization, the Midwest Independent Transmission System Operator, or MISO. Entergy Texas projects net cost savings up to $225 million over a ten-year period by joining MISO. The savings are primarily the result of MISO’s large, more efficient marketplace.

“We spent more than two years carefully reviewing and analyzing all of our options, culminating in our determination that MISO membership would provide the greatest benefits to our customers,” said Joe Domino, president and chief executive of Entergy Texas.

“For decades we’ve worked to plan for the power needs of tomorrow while meeting the demands of today. The proposal to join MISO is one that will allow us to serve our customers’ needs with enhanced reliability and greater efficiency. MISO has world-class reliability tools and a large, mature market that is expected to provide enhanced reliability and allow for a more efficient commitment and dispatch of available generation resources.”

Entergy Texas is seeking to transfer operational control of its transmission assets to MISO with a target implementation date of December 2013. Under the proposed plan, MISO would assume control of transmission planning, the commitment and dispatch of generation that is offered into MISO’s markets, and congestion management. Under the MISO proposal, Entergy Texas would retain ownership if its transmission and generation facilities and would continue to be southeast Texas’ electricity provider; among other functions, MISO would direct the commitment and dispatch of generation offered into MISO’s markets and would administer transmission service over Entergy Texas’ transmission facilities.

Domino said, “By joining MISO’s efficient market, Entergy Texas is creating a more efficient electrical system while enhancing reliability and affordability for our customers.” Initially announced in April 2011, Entergy Texas’ decision to join MISO followed extensive study of all available options to affordably and reliably meet the long-term energy needs of its customers.

Entergy Texas, Inc. provides electricity to more than 400,000 customers in 27 counties. It is a subsidiary of Entergy Corporation. Entergy 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 and it is the second-largest nuclear generator in the United States. Entergy delivers electricity to 2.7 million utility customers in Arkansas, Louisiana, Mississippi and Texas.
