Demand response (DR) is an older concept that was first employed in the United States during the 1970s. As the scale and complexity of DR programs has increased over the last decade, their operational reliability has become more critical and the choices of communications protocols and devices have expanded. There is a need for more centralized management and control, similar to what is done on the power generation side of the electricity market. Numerous vendors have come from many different areas in the industry to offer solutions categorized as demand response management systems (DRMSs). DR plays an important role in the landscape of low carbon policies and regulations, the changing resources mix, and evolving utility business models. Utilities deploy DRMSs to manage their portfoli's of DR programs, address existing compliance and financial risks, and increase customer satisfaction. Drivers range from optimized DR management, customer cost reduction, improved system stability, integration of distributed energy resources (DER), and competitive retail suppliers entering the market. Yet, vendors note that the uptake of DRMSs has been slow. The key barriers to the adoption of DRMS are the high cost of the system and the complexity associated with it. According to Navigant Research, global DRMS spending is expected to grow from $46.1 million in 2016 to $232.3 million in 2025. This Navigant Research report analyzes the DRMS market, covering residential, commercial and industrial, on-premise, and software as a service (SaaS) solutions. The study provides an analysis of the market issues, including drivers and implementation barriers, associated with DRMSs. Global market forecasts, segmented by region and sector (investor-owned utilities, municipal utilities, federal utilities, electric cooperatives, distribution system operators, and retailers), extend through 2025. The report also examines the key technologies related to DRMSs, as well as relevant case studies and the competitive landscape.
