Bridgestone Associates prepared a detailed technical and economic feasibility study for a 12.5 – 23.8 MW Combined Heat and Power (CHP) plant for the Graphic Packaging International paper mill in Kalamazoo, Michigan, USA. The Mill purchases the majority of its electricity from Consumers Energy, the local electric utility. The Mill also generates a small portion of its own electricity using a steam turbine generator. Mills steam requirements are produced in a number of gas fired boilers.
The detailed feasibility study prepared by Bridgestone included a complete analysis of hourly, daily and seasonal energy uses (electricity, steam, etc.), an analysis of existing costs, evaluation of different CHP plant alternative configurations, modeling of their performance using GT‐PRO and GT-MASTER, evaluation of their costs, and a detailed analysis of the financial performance of each alternative.
