Helsinki’s energy company Helsingin Energia produces electricity along with both district heating and cooling by cogeneration in its power plants located in the city. Compared to separate production, this efficient process conserves a considerable amount of raw materials.
In cogeneration plants, the energy contained in the fuel can be almost completely utilised, with the efficiency figure reaching as high as 90%. Overall emissions are also substantially reduced. With cogeneration, each year Helsinki saves an amount of energy corresponding to the annual heating needs of approximately 270,000 detached houses.
City of Helsinki has a long history since 1956 in district energy systems and strong commitment to develop these systems further. District energy systems with diverse and distributed energy supply are easiest and cheapest way in reducing CO2-emissions.
The existing CHC (Combined Heating and Cooling) system in Helsinki provides a replicable and scalable innovative energy production and distribution model for the whole of Europe and why not for the whole of the world to use. In the scale of a city the CHC innovation is significant.
At present, Helsinki is investigating energy production that is less dependent on fossil fuels.
