MISO completes power grid integration


Entergy (NYSE: ETR) and several other power producers and transmission owners integrated their transmission systems on to the Midcontinent Independent System Operator (MISO), a move that is expected to save customers $1.4 billion over a 10-year period.

The four-state integration added 10 new transmission-owning companies, six local balancing authorities and 33 new market participants from Mississippi, Louisiana, Arkansas, Texas and Missouri to MISO. The new region will be known as MISO South, and it helps extend MISO’s operational region from the Gulf of Mexico up through Manitoba, Canada.

Along with Entergy, the following were added to MISO’s grid: Cleco Corp., Lafayette Utilities System, Louisiana Energy and Power Authority, Louisiana Generating, South Mississippi Electric Power Association, and East Texas Electric Cooperative.

Construction is underway on MISO’s new South Region Operations Center in Little Rock to help meet regional needs.
