Regionally generated solar power for Stahlwerk Thüringen

A perfectly sophisticated concept: Agri-PV systems for generating renewable energy.

We currently purchase green electricity from Scandinavian hydropower, which is ensured by guarantees of origin. In future, we would like to use more regionally produced electricity from renewable energy sources to secure our power supply. On an area 3 kilometres long and 2 kilometres wide not far from our plant, the probably largest PV system in Thuringia could be built. With an output of around 100 gigawatt hours per year, it would generate around a fifth of the electricity we need.

It is our explicit wish that the area should not simply be completely covered with solar modules. The ideal solution for this is the design as a so-called Agri-PV system, in which the floor space can be used both for power generation and for agriculture. An excellent example for this can be seen in Kressbronn on Lake Constance where an Agri-PV system covers an apple orchard

In our specific case, high-mounted, partially transparent PV modules and those on movable tracker systems could generate the electricity. The area underneath the modules could be used for fruit growing, poultry farming and grazing. We would then purchase the electricity directly from an operating company as a Power Purchase Agreement with certified green electricity from our neighbourhood. Our SWT Stahlwerk Thüringen Green Steel would mainly be used for the construction of the tracker systems.

The building committee and the municipal council of Unterwellenborn have already approved the project-related amendment to the land use plan and the preparation of a development plan without dissenting votes. The exact design will be agreed with the local residents, the municipality and the agricultural co-operative as the agricultural operator.

Steel that carries climate-neutral energy sources.
