CHP is energy efficient technology that generates electric power and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water that can be used for space heating, cooling, domestic hot water and industrial processes.
Cat gas generator sets can simultaneously provide electricity for electrical loads and heat energy for a facility's thermal requirements. Any Cat natural gas-fuelled engine can be configured specifically for applications involving heat recovery.
Nearly two-thirds of the energy used by conventional electricity generation is wasted in the form of heat discharged to the atmosphere. Additional energy is wasted during the distribution of electricity to end users. By capturing and using heat that would otherwise be wasted, and by avoiding distribution losses, CHP can achieve efficiencies of over 80 percent, compared to 50 percent for typical technologies (i.e., conventional electricity generation and an on-site boiler).
