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.
