Conventional grid-supplied electricity generated by power stations doesn't make use of heat, its by-product, which means that it is inefficient when compared to the calorific value of the fuel used.
By generating power on site and utilising the 'waste' heat, fuel efficiency is maximised. Whilst the engine or turbine of the system may use fossil fuels, typically natural gas, there is a considerable carbon reduction through CHP. Where space allows, biofuels can be used as a fuel source - typically biodiesel and biogas.
We use theoretical or building-gathered load profile data to ascertain whether electrically or heat-lead installations are applicable and to size the installation in order to achieve the optimum financial and carbon payback.
