Through use of a 2.5 MW natural gas generator for peak shaving, an annual savings of ~$500,000 is achievable by reducing demand charges on the grid for a university hospital campus. This design, which yields a net present savings greater than $7,000,000 with an 18.5% ROI, was compared to a tier-2 oil-fired generator, fuel cells, and a natural gas turbine. This study investigated initial cost, demand charge, ratchets, carbon emissions, and practicality to hone in on the best possible design for the owners. These results were presented to the key stake holders for Yale University at the conclusion of the analysis.
