Just after 11:01 p.m. Eastern Daylight Time on May 31, MISO, expanded its reliability coordination services to include eight additional entities in three of its four Southern states.
Combined with operations for MISO's Midwest region, MISO now manages the flow of energy along 65,280 miles of the interconnected bulk electric system from Manitoba, Canada to the Gulf of Mexico.
In addition to providing reliability services for the Entergy companies and Arkansas Electric Cooperative Corp. (AECC), which began Dec. 1, 2012, eight other entities or municipalities are now benefitting from MISO's regional reliability coordination services.
Those companies include Cleco, South Mississippi Electric Power Association (SME); Louisiana Energy and Power Authority (LEPA); Louisiana Generating, LLC (LAGN); and four municipal utilities in the region. With the six Entergy operating companies, these companies together serve more than four million customers
Additionally, the six Entergy operating companies, Cleco and SME are working toward full integration into MISO's market operations by December 2013. As those integration activities continue, MISO posts the progress toward each major milestone on three dashboards, updated monthly. These materials highlight the readiness of Southern region participants, key milestones and activities at MISO.
