Cogeneration systems for telecommunication power plants
This system consists of the following equipment: diesel engine-generators (800 kW*2), an absorption chiller, and a system controller. Electric power is generated from 8 AM to 10 PM. The two diesel engine-generators operate alternately for one week. The reduction in energy cost from February 1989 to January 1990 was approximately 36 million yen. The cogeneration system generated 3700 MWh (the total energy used in the Okayama Network Center was 7000 MWh) and reduced contract power by 900 kW (1700 kW to 800 kW) during this period. The energy efficiency was approximately 65% (generation efficiency was 40%, heat recovery efficiency was 25%).<>
