From a New-Build Apartment to a Large Enterprise
The beginnings of the municipal utility were challenging: After a dispute with the Treuhandanstalt regarding the return of energy facilities to municipal hands, operations began in a new-build apartment in the Winzerla district. At that time, the Stadtwerke had only four employees and 128 district heating customers.
Today, the combined annual turnover of Stadtwerke Energie and its network subsidiary Stadtwerke Jena Netze is around 336 million euros. Management is currently in the hands of André Sack and Claudia Budich.
Focus on Energy Transition and Infrastructure
For a long time now, services related to photovoltaics, electromobility, and heating solutions have been at the forefront alongside traditional supply. As early as 2013, the supply for household customers was completely switched to electricity from renewable energy sources. Electromobility in Jena and the surrounding area is being actively expanded – the company now operates more than 100 public charging points, including charging stations integrated directly into street lamps.
A key focus for the future is district heating supply. As part of a funded transformation plan, the Stadtwerke are working on modernization, digitalization, and efficiency increases. A specific large-scale project is named “ANIKA” (Waste Heat Utilization via Integrated Sewage Treatment Plant): It is expected to go into operation from 2030 as a new, sustainable heat source for the Jena-Nord area.
Local Engagement for the Region
As a municipal company, the Stadtwerke are also involved in society beyond energy policy. With a funding amount of around 15,000 euros per year, approximately 30 regional associations in the fields of sports, culture, environment, and social affairs are supported. Furthermore, the company maintains partnerships with local sports clubs and cultural events.
The restructuring of the energy industry in the new federal states after the political turnaround was a major feat for East German municipalities. Jena was among the pioneers in the successful re-municipalization of networks and facilities. The fact that the first headquarters were located in the Winzerla residential area was no coincidence: The apartment blocks built from the late 1960s onwards were predestined for district heating supply from the start, which remains a key pillar of the company today.
