Berlin took over the more than 2,000-kilometre-long district heating network from energy company Vattenfall in May last year. It supplies around 700,000 apartments in the capital with district heating. The Senate's goal is to make the network completely climate-neutral by 2045. For Vattenfall, the focus was on the separation of fossil energy generation. Senator for Economic Affairs Franziska Giffey (SPD) announced a concrete roadmap for decarbonizing district heating this year. She emphasized that the Senate is building on the existing plans of the former owner Vattenfall. The aim is to update and develop them further.
