Stadtwerke Flensburg GmbH has entrusted Actemium Hannover with the modernisation of Flensburg’s cogeneration plant, which is expected to enter service in 2022. This installation, named Boiler 13 and powered by natural gas, will enable more efficient energy generation and replace two existing coal-fired boilers.

Actemium will handle the installation of electrical, measurement and control equipment; medium- and low-voltage installations; transformers; sub-distribution systems; medium-voltage conductor rails; cabling and cable supports. It will also be responsible for connecting electrical systems components.

Toward carbon-neutral production

This project marks a new stage in the process of modernising the plant. It continues the transition begun in 2014–2016 with the Boiler 12 project in conjunction with Actemium, which centred on the construction of a gas-steam plant offering combined heat and electricity production. Between them, the two new boilers will make it possible to shut down four of the five coal-fired boilers in just six years.

This is a significant environmental benefit, because the new installation will reduce CO₂ emissions by 40% at constant output, enabling the town to avoid 120,000 tonnes of CO₂ emissions per year, the equivalent of driving a car around the world 1,600 times.

The modernisation of its combined heat and electricity power plant will enable the town of Flensburg to meet up to 80% of its urban heating requirement using natural gas. The town will also be able to take pride in having achieved the government’s 2038 coal elimination target well ahead of schedule.
