Over the past several months, our Indiana team has been intervening in a proceeding before the Indiana Utility Regulatory Commission (IURC) to examine Duke Energy Indiana’s coal self-commitment practices. Self-commitment refers to a process by which a utility instructs the regional market within which it operates – in this case, the Midcontinent Independent System Operator (MISO) – to dispatch the utility’s own resource unit regardless of whether or not it is the cheapest available at the time. Many vertically integrated utilities have been using this mechanism to run their expensive coal plants more frequently than economics would otherwise dictate. They do this because it is not their shareholders who suffer financial losses, but rather their captive ratepayers: When the cost to operate these units exceeds the market clearing price, utilities pass along the difference to customers, in part through fuel adjustment clause proceedings. AEE is working to curb this self-serving utility practice.
