Update: On May 8, 2015, Ohio Energy Group (OEG) filed objections to the Compliance Tariff Filing submitted by AEP Ohio on April 24, 2015. In its objections, OEG argued that the AEP’s use of monthly interruptible demand as the basis for calculating the capacity auction credit owed to AEP by customers participating in the IRP program is problematic, since not all of a customer’s total interruptible demand may ultimately clear in the PJM capacity auctions.

On May 12, 2015, AEP filed a reply to OEG’s objections, arguing that imputing PJM auction revenue to IRP customers – regardless of whether they have bid their capacity into PJM auctions or cleared at the current auction price – is a fair and reasonable result. OEG filed a reply on May 13, 2015.
