A new document published by APPA catalogs what some of the largest public power utilities in the country are doing when it comes to demand response. The document breaks the programs out into four categories. The first section, “Customer Information via Smart Grid Tools,” provides examples of utilities that have developed programs that allow their customers to track their energy use each day or even in real-time. The second section of the report lists utilities that have offer time-of-use rates to customers. The third section covers load curtailment programs. These include programs where customers are provided financial incentives to shift their load from peak to non-peak hours. This also includes utilities that inform their customers of impending events that require customers to reduce their electricity usage. The final section lists utilities that have direct load control programs where the utility has installed devices that allow them to cycle appliances on and off during periods of high demand.
The appendices report on data collected by the Energy Information Administration (EIA). Appendix A looks at Advanced Metering Infrastructure (AMI) data, including the number of customers and the amount of load served by utilities that have installed AMI devices. Appendix B summarizes other Demand-Side Management (DSM) data reported on Form EIA-861. The data show that of the nation’s 21.1 million public power utility customers, 12.4 percent are served by AMI. Overall, nearly a quarter of all full-service electric customers now have AMI installed in their homes or businesses. Furthermore, consumers participating in demand-side management programs at public power utilities achieved over 2,000 megawatts (MW) in peak energy reduction in 2011.
