Production

All production is run from Igelsta in Södertälje
The Igelsta plant is situated beside the Södertälje Canal and includes a quay for unloading fuel brought here by boat. Besides the Igelsta district heating plant, the area also contains the Igelsta CPH plant, which is the largest of its kind in Sweden.

The heating plant’s boiler hall contains three large hotwater boilers, three steam boilers, one large and two small reserve boilers and a steam converter that supplies quality-assured steam to AstraZeneca. Each of the hotwater boilers is connected to a flue gas treatment line leading out through the chimney. The boilers also have access aisles for bringing in fuel. In addition, the plant area contains ash silos, fuel tents and a space for sampling, unloading and storing the fuel. Söderenergi’s head offices are also located in the Igelsta plant.

Söderenergi produces both power and heat in the Igelsta CPH plant and only heat in four other facilities: the Igelsta district heating plant in Södertälje, the Fittja plant in Botkyrka, Huddinge Maskincentral in Huddinge and Geneta Panncentral in Södertälje. The two Igelsta plants and the Fittja plant are the largest units.

Heat production totals approximately 1 900 GWh. Of this, 1 850 GWh is delivered to Telge Nät and Södertörns Fjärrvärme AB, which sell and distribute heating to end-customers in Huddinge, Botkyrka and Södertälje. The remainder is delivered to Fortum Värme, with which Söderenergi has a production cooperation agreement. Under this agreement, we supply heat to southern areas of Stockholm during the winter and get heat when the Igelsta plant is shut down for maintenance in the summer.

The district heating network is the third largest conterminous network in Sweden. Production complies with the official guidelines and requirements established for this sphere. All facilities are environmentally certified in accordance with the ISO 14001 standard.
