Suppliers and contractual partners

Do you represent a construction company, engineering office, assembly or civil engineering firm, architectural office, electrical installation company, communications agency or a company in the IT sector?

Then you've come to the right place, because with you as a partner company, we want to enable a climate-neutral future for the capital.

Our supply chain with strong and reliable partners is a key to implementing the necessary investments in Berlin's distribution grid and a prerequisite for the success of the energy transition in the capital.

We set high standards in terms of sustainability and environmental compatibility when selecting, developing and managing suppliers. We therefore want to be a preferred partner for our suppliers and service providers and work together to achieve our goals.
