Expansion of the Tiefwerder substation

We are investing in the future in your district and thus in maintaining and expanding a secure energy grid.

Planned expansion

More and more charging stations for electric vehicles, photovoltaic systems on roofs or balconies are shaping Berlin’s urban landscape. And Berlin’s electricity grid will also cover part of the heat supply in the future. To ensure that our power grid is set up to cover all these tasks reliably, we are renewing and expanding the Tiefwerder substation.

Up-to-date construction information

  • Between Q2/2024 and Q1/2025, the construction site will be prepared, general construction preparations will begin and the excavation pit will be constructed. The civil engineering work will begin. This mainly involves excavating the construction pit, including interim storage and removal of the excavated soil as well as the installation of piles that will support the building's foundations.

  • Between Q2/2025 and Q3/2026, we will start with the shell construction of the extension - the building envelope is being built.

  • In autumn 2026, the shell will be finished and the interior work will begin.

  • From autumn 2026 to 2031, the electrical systems will be delivered and installed.
    The extension and its electrical systems will be completed in 2031.

  • In 2031 and 2032, the outdoor facilities on the site, such as the green areas and lighting, will be completed.

Construction work is not usually silent, nor does it take place without restrictions. You should expect the following disruptions during the construction period:

  • Temporary restrictions / closures on public roads
  • Construction noise on weekdays between 6 a.m. and 6 p.m.

Interruptions to the power supply are not currently planned and will be announced in advance if necessary.

Escape routes and access to private properties will remain open.

Work on the construction site begins at 06:00. Working hours end at 18:00 at the latest.
