A new CHP Facility at Norwalk Hospital is configured to provide the facility with a reliable and efficient source of emergency power. An existing 1,250 kW turbine/generator-heat recovery steam generator line in the power plant was removed and replaced with a new 3,000 kW MWM/Caterpillar engine/generator and waste heat boiler. Additionally, the 27.6 kV substation adjacent to the power plant was replaced with a new 13.8 kV underground service. A mezzanine control room within the power plant contains electrical distribution equipment requiring modifications and new panel additions. Sensitivity to hospital operations, personnel, and the surrounding neighborhood were crucial to a successful execution and were an integral part of the planning and phasing process.
