High-Efficiency CHP Boosts Hospital Infrastructure
A major healthcare provider in Chattanooga, USA, decided for a robust CHP system
Facts & figures

In collaboration with our partner White Harvest Energy, we supported a major healthcare client in the evaluation, sizing, and selection of a high-efficiency Combined Heat and Power (CHP) system to be installed within the hospital’s existing central energy plant. The primary objective was to ensure the hospital could maintain continuous, island-capable power generation while reducing dependence on traditional boilers, particularly for steam used in essential services like laundry. The system was carefully sized to allow at least one engine to operate 24/7, 365 days a year, ensuring uninterrupted support for vital hospital functions regardless of external grid conditions. Over the course of a year, the CHP system is expected to produce approximately 52,000 MW-hours of electricity and deliver a consistent thermal output of 12,000 pounds per hour of 115-degree steam, along with 14,000 MBH of hot water.
With an electrical efficiency of 42.2 % and a thermal efficiency of 44 %, the system achieves a combined efficiency of 86.2 %, offering the hospital a substantial improvement in energy performance. This project not only enhances the hospital’s resilience and operational reliability but also contributes to significant energy cost savings and a reduction in greenhouse gas emissions.
