This report establishes the case for an Energy Imbalance Market (EIM)—a voluntary wholesale electricity market operating in real-time—in the Southeastern United States. While a more comprehensive and widely implemented RTO may ultimately be optimal for the Southeast, an EIM is a straightforward, low-cost first step toward a more efficient and flexible electricity grid that can be achieved without structural reform.
Perhaps most importantly, a traditional EIM is likely to identify more cost-saving opportunities and better balance renewable generation than existing proposals for energy market reform in the Southeast—namely, the proposed Southeast Energy Exchange Market (SEEM).
Specifically, the modeling conducted in this report estimates that an EIM could save $100–600 million annually to Duke Energy alone, which encompasses approximately 40 gigawatts of generating capacity. In contrast, SEEM is projected to save around $40–50 million annually across its full territory, encompassing four times the generating capacity of Duke Energy.
