Microturbine/CHP Demonstration

Marriott Marquis Hotel, New York City, NY


Commercial and industrial electric power consumers are increasingly under pressure to reduce operating costs. Distributed generation technologies such as microturbines may offer consumers an attractive and innovative way to offset high peak energy demand charges. However, uncertainty remains concerning microturbine reliability, availability, power quality, and load-following ability. Site demonstrations of microturbine technologies are important for evaluating equipment performance, for documenting economic and emissions benefits, and to examine the potential for waste heat utilization for steam and/or hot water production.


Project objective is to install two microturbines at a hotel in New York City and assess operating performance in day-to-day commercial service.


Two natural gas-fueled GE-Honeywell Parallon 75 microturbines with recuperators and heat recovery equipment will be installed at the New York Marriott Marquis hotel in midtown Manhattan. Generated electric power and recovered heat will be used on site. Equipment performance will be measured and economic benefits in reduced peak energy demand costs will be documented.


It is anticipated that the Marriott Marquis will reduce annual electric power savings by about $80,000 annually. Additional benefits include deferral of new transmission and distribution capital investment, reduction of electric line losses, reduction in fuel use and cost for heat, reduction in pollutant emissions, and improved power quality.
