Electricity supply
Electricity was supplied from the nearest power station from Schleswag in Lübeck via a high-voltage line to an overhead line pylon outside the arsenal, then forwarded via underground cable to the transfer station
and finally via a 1038 m high-voltage cable to the substation located in the power station,
where the two transformer stations with a total output of 750 kVA with 11KV 50 Hz three-phase current in order to convert it into 400 volt high-voltage current.
In the event of power failures, there were also two diesel generators, each with 500 hp, which
powered generators with a total output of 800 kVA and were connected to the water pipe for cooling. The 10,000-liter diesel tank was buried near the power plant. As a precaution, there was also a 120 cbm
cooling water cistern.
The total length of underground cable for 8 ring circuits in the arsenal was 32 km with 42
distribution points. A further 2.12 km of underground cable was laid for the barracks.
District heating plant
A district heating plant with a maximum output of 12,300,000 WE/h was built to generate heat for space heating, for operational purposes, and for cooking, washing, and bathing.
To circulate the total water volume of 280 cbm, there were two circulation pumps with a capacity of 180 cbm. The heat was distributed to the consumption points via a pipe system with a length of 35 km. For this purpose, there was a pipe system with a total of 57 distribution points in brick-lined underground channels.
Forty-one buildings were connected to the heating plant.
1945–1947 Demilitarization and arsenal dismantling
Three of the seven large boilers and several water heaters were removed from the heating plant,
and one of the two diesel generators and many accessories were removed from the power plant.
Use since 1947
The district heating plant continues to be used and serves not only the industrial area
but also many residential areas in Wahlstedt that have been added in the meantime.
It has been continuously modernized and expanded in recent years.
This has included continuous conversions of the primary energy source, conversion
to a combined heat and power plant, and in 2024, a wood chip heating plant was connected.
After the war, Schleswag took over and operated the power plant.
After operations ceased, the building was sold in 1998 to SGW, Wahlstedter
Sprenggesellschaft, which uses it, with part of it leased to Sylvia Schmedtje's
Ballett & Company ballet school.
