A typical CHP plant will use a fuel (in this case gas) to power a turbine and generator. The turbine produces free heat gases as it generates electricity. This electricity is used on site and can be exported to the grid or supplied directly to the CHP customer. The free heat gases are used to heat water to produce steam via a boiler.
For most of our CHP plants, the steam from the boiler is then used by a steam turbine generator. This reduces the steam pressure to the level required by the customer and at the same time produces even more electrical power.
Our customers can then use this efficiently produced energy for a range of activities including food production, paper manufacture and space-heating for hospitals.
Because this process makes full use of the heat energy produced, CHP is a dramatically more efficient and greener technology than conventional electrical power production.
