Entergy Arkansas signs MISO transmission owners agreement

Entergy Arkansas on Oct. 31 signed the Midwest ISO (MISO) transmission owners agreement (TOA), which is a required document by all transmission-owning members, allowing MISO to work toward full integration of the Entergy Arkansas system by December 2013, a MISO spokesperson said on Nov. 1.

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

MISO received the signature document and Entergy Arkansas’ application to join MISO on Nov. 1, the spokesperson added. 

“This is a big step in the process and gives greater certainty to market participants throughout the region as they prepare for Entergy’s integration into MISO by December 2013,” he told TransmissionHub

MISO filed testimony on Oct. 31 to comply with a request from the Arkansas Public Service Commission (APSC), which directed MISO to file proof that proposed changes to the MISO governance structure, intended to give state regulators more authority, have been implemented. 

MISO filed testimony and exhibits that show MISO has complied with this condition, the spokesperson added. 

Entergy Arkansas President and CEO Hugh McDonald said in Nov. 1 testimony filed with the APSC that Entergy Arkansas is developing a revised Entergy Services agreement.

He also noted that Entergy Arkansas’ plan for compliance with FERC Order 1000 continues to be participation in the MISO Transmission Expansion Planning (MTEP) process, which will begin in June 2013 when Entergy Arkansas and the other operating companies submit their models and assumptions to MISO for inclusion in the 2014 MTEP.

MISO, in an Oct. 31 motion, requested that the APSC enter an order approving Entergy Arkansas’ application to join MISO.

The filing, MISO said, is proof that that its governance proposals A and B have been approved and adopted by the appropriate MISO entities. MISO’s governance proposal A involves enhanced transmission planning authority of the Organization of MISO States, while its governance proposal B involves Federal Power Act Section 205 rights, according to the filing.
