CHP efficiency compares favorably with best in class combined cycle power plant heat rates (ie less than 7000 BTUKWH)

CHP is firm capacity and is dispatchable

Thermal energy may be more profitable than electrical outputPower factor on feeder can be improved

Note Heat Rate calculation includes electrical equivalent of recycled thermal energy)
