Arkansas regulators conditionally approve Entergy move to MISO

Arkansas state regulators on Oct. 26 conditionally approved Entergy Arkansas’ move to the Midwest ISO (MISO).

Entergy Arkansas is an Entergy (NYSE:ETR) company.

The state Public Service Commission (PSC) directed MISO to file proof that proposed changes to the MISO governance structure, intended to give state regulators more authority, have been implemented, MISO added, noting that once the MISO filing has been made, the PSC will issue a final approval.

According to the PSC order, upon satisfactory compliance by MISO with the order, the PSC will issue an order granting conditional approval of Entergy Arkansas’ application subject to the company’s and MISO’s ongoing compliance with previously established conditions, and issue an order establishing a procedural schedule for expedited consideration of MISO’s application for a certificate of convenience and necessity.

According to MISO, Entergy Arkansas has estimated that, as a result of MISO membership, $263m in benefits will be available to ratepayers over a 10-year period. Also, the company will have access to MISO’s Day 2 market.

MISO noted that this approval is the latest development in Entergy’s integration into MISO. Texas state regulators voted Oct. 25 to conditionally approve Entergy Texas’ request to join MISO. Also, Louisiana state regulators approved Entergy Louisiana and Entergy Gulf States Louisiana’s request to join MISO, subject to conditions. MISO further noted that the Mississippi Public Service Commission staff and others have agreed that Entergy Mississippi’s move to MISO is in the public interest. Discussions continue with parties in the City of New Orleans proceeding, MISO said.
