The Federal Energy Regulatory Commission approved a revised joint operating agreement (JOA) between PJM and Duke Energy Progress (DEP) last week despite protests from the RTO’s Independent Market Monitor that it gives Duke favored treatment on interchange pricing.

The revisions to the JOA, which PJM originally signed with Progress Energy Carolinas (PEC) in 2005, were relatively minor, including updates to the company’s name and contact information to reflect Duke Energy’s 2012 acquisition of the utility.

The Market Monitor filed a protest in October contending that PJM should terminate the JOA and negotiate a new one to reflect the joint dispatch agreement (JDA) that PEC and Duke Energy Carolinas signed as part of the acquisition. (See IMM Calls for New PJM-Duke Progress JOA.)

FERC dismissed (ER15-29) the Monitor’s protest, saying that it was challenging unchanged portions of the agreement, not the changes themselves, making the protest beyond the scope of the filing. The commission said the Monitor could file a complaint in a new docket making its case that the dispatch agreement renders the JOA unjust and unreasonable.

In joint comments filed last month, PJM and DEP called the Monitor’s protest “a pretext to rehash old arguments on which the commission has already ruled.”

“Having failed to obtain its desired result in 2010 [when FERC approved the JOA], the PJM IMM now tries for a second bite at the apple,” they said.
