What is Cogeneration?

Combustion engines covert fuel into electricity while simultaneously producing significant amounts of heat. Co-generation, otherwise known as 'combined heat and power' or 'CHP' is the combined production of electric power and the capturing of 'waste heat' to put to other uses. This 'waste heat' is captured via heat exchangers and then utilised in the production of hot water, space heating and cooling, steam and dry air.

The generator itself may run on a range of different fuels such as natural gas, diesel, biofuels and biogas. Currently, the most common form of fuel is natural gas, however the use of biogas and biomass is on the rise. In essence, cogeneration is the thermally efficient way to use fuel by reducing wasted heat. The cost of a cogeneration system can be quickly recovered where there is a high thermal energy requirement, alongside a high electricity requirement, making it a commercially attractive option in the right circumstances. Cogeneration systems can help meet your energy demands more efficiently and therefore reduce your energy consumption and your carbon footprint.

Tri-generation systems work on the same principle set out above, but it refers to the production of heating and cooling alongside electricity.
