Turnkey solution for the substation upgrade: Record commission for the Energy Technology division of EQOS Energie

16. maart 2023
  • New substation for Bischofsheim and Ginsheim-Gustavsburg network area
  • Commission volume in the double-digit millions
  • EQOS concept provides a boost in quality and enables flexible solutions

The Substations/HV Germany South profit center of EQOS Energie is planning and constructing the new “Mainspitze” substation in Bischofsheim on behalf of supply network operator Mainzer Netze GmbH. The background of this project is the remodeling of energy supply systems for the purpose of sustainable power generation and efficient energy usage. “With a commission volume in the double-digit millions, this project is the largest single commission for the Energy Technology division of EQOS Energie and it safeguards the energy supply of a new data centre and the public distribution network of Mainzer Netze and their customers,” said Markus Klein, head of the profit center.

Convincing concept by EQOS

As a full-service provider, EQOS Energie was able to present turnkey solutions for the project. A concept with modular design enables the customer to realise a project that meets higher requirements than originally intended in the tender. It is flexible enough to allow scalable adjustments after commissioning and also leaves room for additional extensions. Klein: “Ultimately, the high quality of our conceptual work was the deciding factor for the award.”

The delivery scope includes three buildings and a 110-kV switchgear consisting of four transformer bays, four line bays, a coupling, a double busbar system with sectional disconnector as well as the associated protection and control technology with auxiliary equipment. At the 20-kV level, an extensive 20-kV switchgear with connected protection and control technology plus auxiliary equipment and an E-compensation system including housing and single-pole switchgear will also be added.

Compared to the minimum requirements specified in the tender, the EQOS concept enables the installation of an additional transformer, and four line bays can be implemented instead of the originally planned three. As a result, the switchgear can be used for flexible network unbundling and it also enables the handling of increasing power requirements in the region, which are also due to the high power demands of a new data centre that is currently being constructed there. One section of the project will therefore be moved up, so that the data centre can be supplied with power as early as the end of 2023. The completion of the overall project is expected at the end of 2025.

Tapping into future opportunities

Uwe Trampnau, Managing Director for the Energy Technology division at EQOS Energie: “The challenges facing Europe’s energy networks are enormous. The energy transformation – moving away from nuclear and fossil fuels and towards renewable energy sources – requires powerful and intelligent infrastructures. EQOS Energie is at the forefront, helping to shape it. In doing this, we are also realising the great future opportunities that arise with infrastructural modernisation. The major commission from Mainzer Netze GmbH in Bischofsheim is an important step on this path and at the same time validates our expertise in the areas of conceptualisation and engineering.”
