Combined heat and power: the economics?

This data-file models the energy economics of a combined heat and power installation, to provide electricity and heating behind the meter, in lieu of purchasing electricity from the grid. The economics are strong, especially for larger units and for fast-charging of electric vehicles.

CO2 emissions can also be reduced by 5-30%compared to purchasing power from the grid, due to high efficiency capturing and using exhaust heat in CHPs.

Economic sensitivities can be stress-tested, including to power prices, gas prices, thermal efficiencies and system sizes (examples below).

The full model also contains granular cost data, c100 rows of operational data for CHP systems and our full notes from the technical literature.
