Eco-efficient city energy by co-generation
Helsingin Energia produces electricity, district heat and district cooling by CHP in its power plants located in Helsinki. When electricity and heat are produced in a single process, fewer raw materials are required than in separate production.
In CHP plants, the energy contained in the fuel can be utilised almost totally, which means high efficiency. At the same time, overall emissions are also substantially reduced. With CHP, each year Helsinki saves an amount of energy corresponding to the annual heat requirement of 270,000 detached houses.
Trigeneration in Salmisaari
In addition to CHP, we also use trigeneration, which means that district cooling is also produced in the same process with heat and electricity. Helsingin Energia has trigeneration in its Salmisaari power plant.
