ENGIE Germany prepares the Großkrotzenburg transformer station for the future

02 December 2022
  • Avacon Netz awards contract for the expansion and conversion of the
    110 kV Großkrotzenburg substation to ENGIE Deutschland
  • The new Power Solutions branch in Gladbeck is responsible for this future-oriented project with an order volume of around one million euros.

Cologne - The energy transition in Germany poses major challenges for the distribution network: As a result of the continuous increase in distributed generation plants, new and reconstruction measures in the grids are becoming necessary. The constantly growing and changing load flows reinforce this development. ENGIE Deutschland is now implementing a solution for this for Avacon Netz: The regional grid operator in Lower Saxony, Saxony-Anhalt, Hesse and North Rhine-Westphalia has commissioned the leading specialist for technology, energy and service to expand and convert the 110 kV Großkrotzenburg substation. On the one hand, the services comprise the primary installations including the installation of the grounding mesh, the grounding and disconnecting switches, the transformer sets and the complete primary technical stranding and piping. On the other hand, the ENGIE team is responsible for the secondary installations including the connection of the control and protection technology as well as the changeover of the existing systems to the new control technology. In addition, there are still the secondary trades, which include the installation of the new operations building and the relay houses and the air conditioning of the control room. The corresponding measures started in September 2022 and are scheduled for completion as early as October 2023. They are part of a major project in Frankfurt am Main with a total volume of 750 million euros, in which power lines and substations are being made fit for the future, thus securing the growth of the world's largest Internet hub. This is why the project is considered a lighthouse project for the whole of Germany.


New Power Solutions branch realizes project for the future

The Power Solutions branch of ENGIE Deutschland, which opened in July 2022 and is based in Gladbeck, is responsible for the contract. The team of the new branch will grow to 100 employees by January 2023 and consists of specialists in electrical and control engineering and mechanics. They offer customers throughout Germany comprehensive services and sustainable solutions for power generation, distribution and supply plants. Further information is available online at:
