Yesterday, the Public Utilities Commission of Ohio (PUCO) voted to delay action in its case to determine whether Akron-based FirstEnergy Corp. "overpaid for renewable energy credits and passed those excess costs on to customers," The Associated Press reports (See our Aug 23, 2012, blog post for more information). PUCO Chairman Todd Snitchler said the delay is to allow time for the commission to "fine tune" its order. In June, the Ohio Power Company Corp. (AEP Ohio) moved late to intervene and request that the proceeding be reopened, saying it had "extraordinary circumstances" under which such a motion should be allowed. In its motion to intervene, AEP Ohio said the "nature of the issues involved in the case progressed beyond a limited audit of FirstEnergy Companies' rider and now involve significant energy-wide questions relating to compliance with renewable standards." The company seeks to address "gaps in information provided the commission" with regard to methods used by other utilities "that have operated in [the] same market" as FirstEnergy and were "able to manage costs." Confidentiality claims made by FirstEnergy with regard to portions of audit reports have prevented AEP Ohio and other utilities from discussing the details of the overcharges.
