Distributed energy resources allow electricity to be generated closer to where it is used, protecting businesses and institutions from unexpected outages caused by natural disasters and other disruptions. The U.S. national laboratories as well as public-private partnerships provide financial resources and access to research facilities to foster innovations to modernize the power sector from a 100-year-old centralized system to one that incorporates disparate clean technologies such as microgrids, batteries, and energy smart tools. These investments and the resulting new products and capabilities decrease costs, improve grid reliability, reduce emissions, and offer consumers more options.
Energy storage technologies encourage adoption of renewable energy by addressing generation variation resulting from weather conditions. They also aid local utilities by providing an array of grid-balancing services, such as peak shifting—shifting grid usage by consumers from periods of high demand to less intensive times— and backup power supplies. These characteristics support a cleaner and more reliable electric system and present an important market opportunity for the clean energy economy.
