SUNfarming and SPIE realise substation from largest agri-solar project in Europe

Steinhöfel, 28 August 2024 - SUNfarming GmbH (the leading developer and investor for agrivoltaic systems in Germany) is working with SPIE (the independent European market leader for multi-technical services in the energy and communications sectors) to build the substation for green electricity from Europe's largest agrivoltaic project ‘Klimapark Steinhöfel’. This extends across eight districts and will connect a total installed capacity of up to 753 megawatt peak (MWp) to the grid. The plant with a total of four transformers will ensure that the energy generated is reliably fed into the existing high-voltage grid of the regional distribution grid operator E.DIS via 110-kilovolt cable systems.

The Steinhöfel climate park is a lighthouse project in the photovoltaic sector and combines sustainable energy generation with genuine agricultural production on an area of around 500 hectares. Innovative designs and technologies enable efficient and sustainable dual use of the agricultural land with light and rainwater management under the DIN SPEC-compliant bifacial glass-glass PV modules at a minimum height of 2.10 metres. This dual utilisation has lasting positive effects on animal welfare and husbandry, biodiversity, CO2 reduction, groundwater protection and agricultural yield security on the sandy soils in this region, which have been difficult to cultivate up to now. SUNfarming developed the agricultural concept for the Steinhöfel climate park in close cooperation with an agricultural consultancy for local farms and local farmers and brought it to the planning permission stage within a four-year development period. Once the agri-PV systems have been built, the agricultural land will be used as perennial fodder production areas and as temporary portion pastures for calf and heifer rearing.

SPIE is providing all services for this project, from planning permission and implementation planning to the entire procurement of materials for the substation, primary and secondary planning, installation and commissioning. ‘With our technical solutions, we enable the integration of renewable energies and thus create the infrastructural prerequisites for the energy transition and a climate-friendly future,’ says Burkhard Sager, Head of the High Voltage division at SPIE Germany & Central Europe. ‘We are pooling our decades of experience to realise this complex project,’ adds Hannes Weinreich, Head of the Green Substations department in SPIE Germany & Central Europe's High Voltage division. ‘The main challenge here is the tight schedule, in which many work steps have to dovetail precisely for a project of this magnitude to succeed

‘The Steinhöfel Climate Park is the largest SUNfarming pioneer project, which we have successfully developed in just under four years with the statute resolutions in all districts,’ explains Martin Tauschke, co-founder and Managing Director of SUNfarming. ‘We can only realise this ambitious project thanks to the very good and close cooperation with the municipality of Steinhöfel, the citizens of the region, the Oder-Spree district, our agricultural landlords and our technical partners.’ SUNfarming has been developing and researching its own Agri-PV systems for more than 10 years. ‘Our agri-PV solutions convince farmers and investors alike,’ explains Edith Brasche, Managing Director of Project Development at SUNfarming. ‘We are currently developing several gigawatts of agrivoltaic systems - for use in crop and fruit growing as well as for keeping suckler cows and calves, poultry and fallow deer. The Steinhöfel climate park is part of our research to prove that agrivoltaic systems protect the environment, nature and groundwater against climate change and bring real added value to rural regions,’ says Brasche.
Work on the substation is expected to begin in the third quarter of 2025, with commissioning planned for the second quarter of 2026. The first parts of the Agri-PV park in Steinhöfel will be connected directly to the grid via the substation once it is commissioned.

As a driver of the energy transition, E.DIS Netz GmbH is proud to contribute its expertise and support to this pioneering project. As a long-standing supporter and driver of the energy transition in the region, E.DIS Netz GmbH is significantly involved in providing the grid connection at the Steinhöfel substation, which serves as the hub for feeding green electricity from Europe's largest agri-solar project. ‘Our partnership in this project underlines our ongoing commitment to developing innovative solutions for a sustainable energy supply,’ emphasises Petra Kortenkamp, Head of Individual Customers at E.DIS Netz GmbH. ‘For over two years, we have been intensively involved in the planning and realisation of the technical grid connection, which enables the renewable energy generated to be efficiently integrated into the grid. Our focus here is on a forward-looking and secure energy infrastructure.’ E.DIS Netz GmbH sees this project not only as a significant investment in the regional energy industry, but also as an important step towards a climate-neutral future. ‘This project impressively demonstrates how collaboration and technological innovation can pave the way for a sustainable energy future.
‘This project is an impressive demonstration of how collaboration and technological innovation can pave the way for a sustainable energy future. We are determined to further strengthen our contribution to the energy transition and to promote and implement innovative projects that drive the energy transition forward,’ adds Petra Kortenkamp.
