Connecting the future

Green energy for tenants and e-mobility: Deutsche Wohnen plans to install 1,000 solar panels on rooftops in many of the company’s neighbourhoods. Two thousand charging stations for electric vehicles are also planned. “A huge contribution to the energy transition in cities,” says Stefan Haake, CEO of Deutsche Wohnen Technology GmbH.

Mr Haake, kitting out a thousand roofs with solar panels in one single project can’t be something that happens very often in the German housing sector, right?

That’s true, but we set ourselves the goal of ensuring decentralised energy supply for our portfolio. This allows us to get locally sourced green energy straight to our buildings’ residents. And we didn’t want to do it by halves. Why? Because it’s an important issue. The fact remains that a significant proportion of Germany’s energy consumption is in the housing sector. At the same time, there’s the target to make housing stock climate-neutral by 2050.

Deutsche Wohnen could just buy green energy and supply it to its tenants, though, couldn’t it?

It’s much better to generate the energy you need in buildings right there where it’s needed and not to transport it over long routes. This helps protect resources and ease the burden on electricity networks.

How much carbon dioxide will the 1,000 panels save across Germany?

Small solar panel facilities with a top performance of 38 kilowatts peak (kWp) already save around 14 tonnes of CO2 per year through decentralised energy production. That means we can save 14,000 tonnes of CO2 per year through all our panels. For comparison: to offset a tonne of CO2 per year, you would have to plant around 80 trees.

How much is Deutsche Wohnen investing in this project?

We estimate costs of around EUR 50 million for the solar panels. At the same time as we expand solar panels, we also have plans for major expansion of e-vehicle charging infrastructure in Deutsche Wohnen’s residential neighbourhoods. Two thousand charge points across Germany are planned. With this project, we’re making a major statement about the mobility transition in cities. We’re investing around another EUR 25 million in this scheme.
