Demand response—temporary changes to electric loads in reaction to conditions in the grid—has grown to become an important part of today’s power systems and a central component of the smart grid of the future. In the United States, the aggregate impact of demand response (DR) is estimated at 58 GW, or 7.6 percent of the peak demand,1 up 42 percent from two years ago.2 The Federal Energy Regulatory Commission (FERC) views the potential for further cost-effective DR to reach as much as 20 percent of the system peak.3 Today, the cost-benefit analysis for DR is underway for electric systems around the world, with proponents pointing to cost savings, environmental benefits and increased reliability as reasons to invest in a more responsive electric system.4

While demand response has gained traction among stakeholders in the electricity industry—e.g., utilities, regulators, customers and service providers—the adoption of demand response has varied significantly across geographies. Some regions have embraced the concept and show remarkable results; one electric cooperative in Minnesota reports that nearly half of its 700,000 residential customers are enrolled in a program that allows utilities to remotely cycle off their air conditioners during peak events.5 In contrast, other areas have developed little or no demand response.
