Also on November 22, PJM’s IMM filed a complaint requesting a market participant, American Electric Power Service Corp. (AEP), to provide the IMM with certain information that AEP allegedly refused to provide in response to information requests. According to the complaint, the IMM requested that AEP provide the data from which AEP calculates the variable operations and maintenance expense component of its cost-based offers, which was requested in order to determine whether the level of AEP’s cost inputs for cost-based offers raise market power concerns. The IMM claims that it is unable to obtain such information from an alternative source, so the IMM requests that FERC require AEP to provide the requested information within two weeks.
