Utilities and their regulators are increasingly taking steps to foster reductions in electricity demand — whether through improved efficiency in applications or demand management — based on a combination of economic, reliability, and, increasingly, environmental reasons.
FERC's recent creation of an Energy Innovations Sector (EIS) within the newly renamed Office of Energy Market Regulation (OMER) (formerly the Office of Energy Markets and Reliability) is intended to highlight and respond to the growing complexity and potential of demand response in U.S. electric power markets. The EIS will focus on five areas—demand response, renewables, distributed generation, global warming and advanced technologies—and will be tasked with performing independent assessments of developments in each of these areas as well as serving as an in-house technical advisor on issues regarding the integration of these resources into FERC's traditional concerns of wholesale markets, reliability, transmission planning and resource adequacy.
Regional collaborative efforts to encourage demand response are also gaining traction in the form of the Pacific Northwest Demand Response Project and the Midwest Demand Response Initiative in the last year. In addition, the California Independent System Operator (CAISO) plans to open a demand response laboratory this month in an effort to educate consumers on the potential for and importance of demand response. The lab will feature exhibits and information on the latest demand response technologies, ranging from thermostats that respond to FM radio signals to adjust air conditioning and other residential applications to an automated direct response programs for commercial and industrial clients. The latter allows utilities and other demand response aggregators to bid in MW blocks of demand reduction at certain prices and allocate the revenue as they wish. Increasing numbers of utilities are using programs such as these to meet supply. Finally, the addition of third-party demand response providers to the mix further expands the range of demand response options.
FERC's Assessments of Demand Response and Advance Metering, issued in August 2006 and again in September 2007, demonstrate, according to FERC Commissioner Wellinghoff, that implementation of demand response programs has shifted from a question of "whether" to a question of "how." FERC plans to issue another report in 2008 and follow up every two years thereafter, with information updates in the intervening years.
Other nationwide efforts are also underway to quantify and verify demand response resources. Quantification can prove difficult since reliability-based demand response resources, such as direct curtailments or interruptible services, are easier to track than are economically induced resources that depend on variable levels of customer participation. Both NERC and NAESB have undertaken efforts to calculate demand response potential in the U.S. Also, the US Demand Response Coordinating Committee (DRCC), a group composed of utilities and other energy companies, is working to develop methods for verifying the contribution of demand response resources.
