The Federal Energy Regulatory Commission has scheduled a hearing over how much Duke Energy will pay to resolve its obligations for transmission expansion projects in MISO after settlement talks collapsed.

Administrative Law Judge Philip C. Baten ordered a prehearing conference for April 1, in preparation for a scheduled Oct. 21 hearing in the case (ER12-91), which resulted from the move by Duke Energy’s Ohio and Kentucky utilities from MISO to PJM in May 2010.

In September, FERC rejected a settlement by Duke’s affiliates, ruling that the agreement unfairly imposed transition costs on transmission customers who were not party to the agreement. (See FERC Rejects Settlements over ATSI, Duke Moves to PJM.)

Baten ordered the case to hearing after the parties indicated at a settlement conference March 10 that they were at an impasse.
