Application of Thermal Storage, Peak Shaving and Cogeneration for Hospitals

摘要

Energy costs of hospitals can be managed byemploying various strategies to control peakelectrical demand (KW) while at the same timeproviding additional security of operation inthe event that an equipment failure or adisruption of power from the electric utilityoccurs. Some electric utilities offer theircustomers demand (KW) reduction rate incentives.Many hospitals have additional emergency back-upneeds for electrical energy. Demand isrelatively constant in many hospitals due tohigh internal loads. These factors coupled withthe present competitive alternate fuel marketand present opportunities for hospitals tosignificantly reduce operating costs and provideadditional stand-by or back-up electric sources.This paper employs a hospital case study todefine and illustrate three energy planning strategies applicable to hospitals. Thesestrategies are peak shaving, thermal storage,cogeneration and/or paralleling with theelectric utility.
