Resort Hotels should be considered for application of co-generation to take advantage of higher thermal efficiency and consequent energy cost avoidance. Modern resort hotels require comfort and reliability from mechanical and electrical systems on an around the clock basis. Load profiling reveals simultaneous process heating and electricity use requirements that aid in the selection and sizing of co-generation equipment. Resort Hotel needs include electrical loads for lighting, fan motors, elevators, escalators and receptacle uses. Process heat demands arise from kitchen, servery, banquet, restaurant, laundry, and bakery functions.

Once the loads requiring service have been quantified and realigned (shifted) to maximize simultaneous demands the engineering task of co-generation application becomes one of economics.

National legislation is now in place to foster the use of co-generating central utility plants. Serving utility companies are now by law required to buy back excess energy during periods of reduced hotel demands.

Resort Hotel loads, converted into electricty and heat demands are tabulated in terms of savings (positive cash flow) or costs (negative cash flows). Cash flow tabulations expressed in graphs are included. The graphs show the approximate simple payback on initial costs of co-generation systems based on varying electricity charges.
