Combined Heat and Power (CHP)

The essence of CHP is to generate both heat and electricity. This translates into significant energy and fuel savings, as well as substantial CO2 emission reduction. CHP is already implemented in large-scale electric power stations providing heat for district heating that would otherwise be wasted. On a smaller scale, CHP is currently successfully used in greenhouses in the Netherlands.

Micro CHP

Micro-CHP is combined small-scale heat and power generation at locations where both are demanded. Commonly, heat demand drives operation of the micro-CHP system. The electric power thus becomes a by-product, being produced at a very low cost price. The main advantage of micro-CHP is that the energy in the fuel is almost fully utilized. This stands in contrast to conventional power plants, where substantial amounts of heat are lost into the atmosphere or in cooling water. Moreover, micro-CHP saves transmission and distribution losses of electricity from power stations to end-users.

Micro cogeneration of electricity at the end user’s location yields significant cost savings due to the lower price of natural gas compared to electricity from the grid.

Any excess electricity generated will be exported into the grid. Utilities providing electricity usually pay export fees. This makes the benefits of cogeneration even greater. This fee is called a feed-in tariff.

NB: In Germany exists an energy generation bonus, which is given both to feed-in electricity as well as to generated electricity used by the owner.
