TSCNET shareholder Amprion, one of the four German transmission system operators (TSOs), is expanding its Siegburg substation in North Rhine-Westphalia, near the former seat of the West German government in Bonn. The planning is progressing well: By 2023, the existing 220/110kV substation is to be integrated into the 380kV grid. To this end, the current installations will be extended by a 380/220kV transformer and a gas-insulated switchgear at the 380kV voltage level. A new overhead line will connect the station to Amprion’s supra-regional transmission system.
But there is more to be told from Siegburg, as the substation provides a home for seven bee colonies. In May, further TSCNET shareholder TenneT, the Dutch-German TSO, reported on a pilot project on eco-friendly substation maintenance, and now Amprion also informs about new steps in this field: Around 350,000 bees of the Buckfast and the Carniolan breeds live in a specially fenced area and bring the nectar gathered on their flights back to the hives at the station. “We are very happy about our new neighbours,” says Klaus Breitbach, operations manager of the substation. “We hope that our new neighbours will thank us for the good location with one or the other glass of honey”.
News is also coming from the Bischoffsheim substation in the Rhine-Main Area. Here, too, Amprion is working on the grid of the future: To ensure security of supply for the region and the state capitals of Mainz (Rhineland-Palatinate) and Wiesbaden (Hesse), the TSO is expanding and modernising the existing 380kv system with a transformer and switch panels. On 27 July, Amprion expects the delivery of the 350MVA transformer. First, the transformer with a weight of around 350 tonnes is being transported by rail. The last 560 meters on the road will be taken over by a heavy haulage tractor unit with a length of 78 meters and two times twelve axles. The total weight of the transport unit is 574 tonnes.
