Eulenberg substation

In the south-west of Magdeburg, Eulenberg high-tech park is being built. The prominent first customer to settle here is Intel. The chip manufacturer has decided to build a new semi-conductor chip factory near Magdeburg. The factory, as well as the other suppliers that will take up residence in the high-tech park, require a lot of electricity: in the first building phase, 50Hertz will already provide a capacity of around 400 megawatts (MW), while in the final stage of expansion, this capacity is expected to be four times as high.

To ensure the supply of electricity to the industrial site, 50Hertz, regional distribution system operator Avacon and the municipal utility Städtische Werke Magdeburg are working closely together. The project partners are currently drawing up the application documents.

You can learn more about the project and the current planning under Status.

50Hertz is actively pursuing greater use of renewable energy. In 2019, renewable energy sources already covered around 60 percent of the electricity demand in the north-east of Germany. By 2032, the coverage in our grid area should be 100 percent.

This high share of green electricity was already an important argument for the settlement of companies such as Tesla and is undoubtedly equally important for the Eulenberg site. With the near-term supply of the Eulenberg high-tech park, 50Hertz is making an important contribution to the energy transition and the economic development of a high-potential region.

Status

Necessity

The need for the substation results from the designation of the Eulenberg high-tech park as an industrial site with an extent of around 450 hectares. The largest settlement here is the planned production site for computer chips by US semiconductor manufacturer Intel. In addition to Intel, other companies are expected to settle there as well.

The new substation will also reinforce the surrounding grid areas of distribution system operator Avacon and the municipal utility Städtische Werke Magdeburg and will make the region fit for other prospective industrial businesses as well as more renewable energy feed-in. All these factors combined make it necessary to build a new substation on site.

Permitting

The substation sections in responsibility of Transmission system operator (TSO) 50Hertz and distribution system operator (DSO) Avacon are subject to separate permitting procedures. 50Hertz submitted its application documents to the city of Magdeburg in November 2022.

50Hertz’s part of the installation requires an application in accordance with the Federal Immission Control Act (Bundes-Immissionsschutzgesetz, BImSchG), whereas Avacon is applying for a building permit. This difference is due to the voltage levels involved. The permitting authority for both applications is the city of Magdeburg.

50Hertz and Avacon are expecting to receive the permits in 2023.

Planned location

The substation will be built to the east of the high-tech park, directly west of the Magdeburg-Sudenburg motorway junction, where a 380-kilovolt (kV) overhead line of 50Hertz and a 110-kV overhead line of local DSO Avacon are already in place. The positioning within the area will minimise the need to construct additional connecting lines.

The exact location of the building site is the object of an ongoing development plan procedure (Bebauungsplanverfahren).

According to the current planning, the final development of the joint 50Hertz-Avacon substation may cover up to 28 hectares. This will allow for installation expansions on the site of the substation itself.

Technology and construction method

Visually and technologically, the installation will resemble a classic substation. This includes gantry pylons for overhead line conductors, lightning protection masts, surge arresters, disconnectors, a switchgear bay to distribute the electricity within the substation as well as transformers to alter the voltage level from 380 to 110 kilovolts. One particular feature will be that the installation will be L-shaped because of the local conditions, so that the available space is used best possible.

Sustainability aspects are taken into account – ranging from biodiversity in the open spaces to the avoidance of greenhouse gases for insulating purposes (such as SF6) in the substation as far as possible.

The busbar connects to the 110 kV level and also forms the property limit with Avacon’s part of the installation. At this voltage level, Avacon takes care of the connection to the surrounding distribution grid as well as the connection of the grid customers and of the Städtische Werke Magdeburg, for which a transformation to medium voltage level will be established.

Furthermore, single-storey buildings are built on the site to house the monitoring and control systems.

Once the permit has been granted, construction can start in 2023. Commissioning is planned for 2026.
