Total System Efficiency definition

Total System Efficiency means the sum of the net useful electric energy output measured in British Thermal Units (BTUs) and the net useful thermal energy output measured in BTUs divided by the total fuel input. “Useful thermal energy output” means energy (1) in the form of direct heat, steam, hot water, or other thermal form that is used in production and beneficial measures for heating, cooling, humidity control, process use, or other valid thermal end use energy requirements and (2) for which fuel or electricity would otherwise be consumed. It does not include thermal energy used to dry or refine biomass fuel.
