EnerNOC (s ENOC) has seen its COO retire and its shares drop to 18-month lows after grid operator PJM complained that unnamed demand response companies were practicing “double counting” of assets in a way that could allow them to cover up under-performing customers while reaping an unfair financial reward. PJM’s statement (PDF) described a complicated practice that allows curtailment service providers (CSPs) to count customers’ ability to turn down power under multiple programs. PJM called the practice a “market manipulation that results in overpayment for curtailments and may ultimately jeopardize reliability.” It also could allow CSPs to sign up customers with the knowledge that they may never have to actually deliver the reductions they’ve promised to, if a big, “double-counted” customer can be relied on to cover the gap. There’s no specific link between EnerNOC, the country’s largest demand response company, and PJM’s accusations, and the Mid-Atlantic grid operator does operate the largest demand response market in the country. We’ll be waiting for more clarity on PJM’s accusations and how they may affect EnerNOC and other big demand response providers that serve it, including Comverge and CPower (now owned by Constellation Energy).
