Lower Saxony largest rooftop PV system

in the seaport of Brake

Significant milestone for sustainable energy supply

31,000 solar modules on a total of ten halls of the harbour operator J. MÜLLER in Brake/Unterweser generate green energy. They generate a solar yield of 959 kWh/kWp and avoid over 5,800,000 kg of CO2-emissions every year. In other words, the PV system supplies enough sustainable energy to power 3,400 households a year.

The largest rooftop photovoltaic system in Lower Saxony has now been put into operation in a festive ceremony. In the presence of high-ranking guests from politics, business and society, Lower Saxony Energy Minister Christian Meyer emphasised the great importance of this project for the climate and environment and the efforts to transform the seaport of Brake into a “green port”.

11 million euro project successfully realised

The gigantic system was planned, built and put into operation by our colleagues from Bremen. “We decided in favour of SCHULZ Systemtechnik because of the many years of cooperation,” says Cedric Witten, Head of Technology at J. MÜLLER. “With an investment sum of 11 million euros, it is important to have a partner who can handle such a project.”

“The task we were given here was the installation of the approx. 12 MWp PV system as well as the installation of the upstream and downstream infrastructure in the form of 20 KV systems with a total of ten transformers,” says Heino Platter, project manager for medium-voltage and low-voltage systems. Our colleagues have accommodated the energy technology in four focus stations and set up a 20 KV ring with a length of approx. three kilometres. The concrete stations themselves were developed and built in collaboration with Björn & Peter Renken, a construction company based in Brake.

J. MÜLLER AG generates 30% of its electricity requirements by itself

On the harbour site J. MÜLLER operates Europe largest connected silo facility and requires a great deal of energy for its handling operations.

“By equipping the unused hall roofs with photovoltaic modules, we can now generate over 30 per cent of the electricity we need ourselves and thus further reduce our ecological footprint”, says a delighted Cedric Witten, who always has an eye on the electricity yield via an energy dashboard.

Jan Müller, CEO of J. MÜLLER AG, is also more than satisfied. “The photovoltaic system is a milestone in our endeavours to implement sustainable energy solutions.”

We can also draw a positive balance at SCHULZ Systemtechnik. “In terms of volume, this project is the largest PV project for us. We are proud to have managed everything so smoothly and look forward to continuing our collaboration with J. MÜLLER”, sums up Heino Platter.
