Mississippi Baptist Medical Center (MBMC) is a 624-bed hospital in Jackson, Mississippi that installed a 4.6 megawatt combined heat and power (CHP) system in 1991 to provide 80% of its electrical needs, 95% of its steam demand, and 60% of its cooling. During Hurricane Katrina in 2005, the CHP system provided power and thermal energy to the hospital for over four days when the electric grid was down, allowing MBMC to remain operational and serve other facilities. The CHP system saves MBMC over $800,000 annually in energy costs.
