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 2^nd quarter 2024 and 1^st quarter 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 2^nd quarter 2025 and 3^rd quarter 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:

• Work will take place on weekdays between 6 a.m. and 8 p.m. (depending on the season) and will result in increased noise levels during certain phases.
• Construction noise will not occur throughout the entire construction period, but only during individual phases that are necessary for construction purposes.
• Access to private properties will remain unaffected, but there will be restrictions on public roads.
• Emergency routes will remain open at all times.
• There will be no planned power outages.
