The Rosen Group has completed the installation of a large-scale photovoltaic system at its corporate site in Lingen, Germany, marking a step in its renewable energy strategy.

Developed in partnership with Stadtwerke Lingen, the two-megawatt solar installation represents an investment of around €2 million ($2.3 million) and is now fully operational.

Approximately 4,500 solar modules were installed across nearly all suitable building roofs, covering around 9,000 square meters.

A smart energy management system enables demand-based electricity use, with 98.7 per cent of generated power already consumed directly on-site.

Further measures to increase self-consumption are under review.

The project required extensive technical coordination, including upgrades to the site’s energy infrastructure, the integration of seven transformer stations, and the installation of around 21,000 meters of cable.

Covering the company’s 35-hectare facility, the system ranks among the region’s most significant renewable energy projects.

The companies have already announced plans for further expansion, with around 1,000 additional modules expected to add 450 kWp of capacity.

The project demonstrates the potential of regional cooperation in advancing renewable energy and supporting the energy transition in the Emsland region.

“By commissioning this system, we are reducing our CO₂ emissions while simultaneously strengthening our self-sufficiency in renewable energy. The project is a key component of our sustainability strategy and demonstrates how we are taking responsibility for the long-term development of our company in Lingen,” said Carlos Sabido Ponce, Managing Director of Rosen Technology and Research Centre.

“This project exemplifies the successful collaboration between Rosen and Stadtwerke Lingen. We have been united by a partnership based on trust for more than 40 years. We are all the more pleased that together we were able to implement a solution that combines economic, environmental, and regional interests,” said Thorsten Schlamann and Hermann Cordes, Managing Directors of Stadtwerke Lingen. -OGN/TradeArabia News Service
