Microgrid Cuts University of Missouri Coal Consumption by 73%

Extract from article by Elisa Wood

The University of Missouri (Mizzou) has been able to reduce its coal consumption by 73 percent through use of highly efficient and sustainable microgrid technologies - moving it significantly toward its carbon reduction goals.

The college's efficiency achievements are in keeping with its long history of energy innovation. Mizzou's full service energy center has evolved since the late 1800s when Thomas Edison donated one of his earliest steam turbine driven electric dynamos (DC generator).

When MU illuminated Academic Hall in 1883, it was one of the first demonstrations of incandescent light west of the Mississippi. Today, the large and complex microgrid serves a 15-million square-foot campus in Columbia, with a campus population of more than 34,000 students. The 66-MW energy center employs four coal-fired boilers, a 100-percent biomass-fired boiler, four steam turbine generators, a dual-fuel oil and gas-fired boiler, and two Solar Titan gas turbines with heat recovery steam generators and sophisticated controls.

The sustainable microgrid is interconnected with the local municipal utility through a 69-kV tie line, and leverages favorable wholesale market prices through MISO when possible. When grid prices are high, the university relies more on its on-site power generation. This interconnection also allows MU to contract for renewable energy generated off site such as wind and solar.
