Demand for electricity can spike during just a few hours a year, and typically 10 percent of our electric system capacity is built to meet demand in just 1 percent of hours during the year. This comes at a significant cost to consumers. Last week, Advanced Energy Economy released a new report, “Peak Demand Reduction Strategy,” showing that states that implement peak demand programs can significantly reduce costs for customers, strengthen reliability of electric service, and ease compliance with EPA’s Clean Power Plan. The day before, the U.S. Supreme Court heard oral arguments in a case that will determine whether the Federal Energy Regulatory Commission (FERC) has authority to regulate payments for demand response, a primary mechanism for reducing peak demand. In all, it was a big week for efforts to get spikes in electricity demand under control.
