What are some examples of smart microgrids?
U.S. Army Fort Bragg
Fort Bragg, North Carolina
To enhance power reliability while reducing costs, Fort Bragg, a U.S. Army base near Fayetteville, N.C., elected to build one of the world’s largest microgrids. With guidance from Honeywell, Fort Bragg integrated a variety of distributed generation technologies that work in conjunction with the military base’s utility infrastructure. Covering more than 100 square miles, Fort Bragg owns its own electric distribution network and is able to monitor various generations from a central energy management center. Despite its size, the various generation technologies are fully integrated with the post’s distribution network, information technology and communications infrastructure. As a result of its smart microgrid distribution system, Fort Bragg has enhanced its energy reliability and reduced overall energy costs.
Beach Cities Microgrid Project
San Diego, California
The Beach Cities Microgrid Project in San Diego has brought together some of the nation’s biggest names in the energy industry to learn more about how a smart microgrid in the San Diego area would work under real-world conditions and ultimately reduce peak loads by more than 15 percent. This effort is led by San Diego Gas and Electric in partnership with Horizon Energy Group, Advance Control Systems, Motorola, IBM, Lockheed Martin, Pacific Northwest National Laboratory and the University of San Diego. Together, they developed a system that incorporates multiple distributed generation systems, such as solar power in homes and businesses, biodiesel-fueled generators, distributed energy storage devices and demand response technologies such as smart meters.
Perfect Power at Illinois Institute of Technology (IIT)
IIT has partnered with the Galvin Electricity Initiative and the United States Department of Energy (DOE) to develop a Perfect Power System — a smart microgrid for the IIT main campus. In collaboration with S&C Electric, Endurant Energy and ComEd, the university is building an electricity system of interconnected smart microgrids in a loop configuration with a redundant electricity supply. Construction on this system is under way, and it will offer IIT the opportunity to eliminate costly outages, minimize power disturbances, moderate an ever-growing demand and curb greenhouse gas emissions. It is estimated that the system will pay for itself as it is built over the next five years.
