Deutsche Infineum and RheinEnergie to Develop One of Germany's Largest Inner-City PV Installations
Major Contribution to the Energy Transition: Contract Signing Marks Landmark Ground-Mounted Solar Project for Cologne's Industrial Sector
COLOGNE, Germany, Feb. 19, 2026 /PRNewswire/ -- RheinEnergie AG and Deutsche Infineum GmbH&Co.KG have signed contracts for the construction of an 18-megawatt ground-mounted photovoltaic installation at Infineum's industrial site in Cologne. With a projected annual output of approximately 18 million kilowatt hours, this is set to become one of the largest ground-mounted PV installations on inner-city industrial land in Germany. Commissioning is scheduled for 2027.
Milestone for the Decarbonisation of Cologne's Industry
Approximately 25,300 solar modules, each with a capacity of 710 watts, will be installed across some 12 hectares. The facility on Neusser Landstraße will generate enough surplus electricity each year to meet the energy requirements of approximately 6,500 households. Through this project, Infineum is making a substantial contribution to reducing CO₂ emissions at its Cologne production site, with potential savings of up to 6,500 tonnes of CO₂ per year.
"With this installation, we are sending a powerful signal together with Infineum for the future viability of Cologne as an industrial location," sais Stephan Segbers, Board Member for Sales at RheinEnergie AG. "This project demonstrates how we can support local businesses in their decarbonisation efforts through renewable energy solutions."
Dr Martin Halama, Managing Director of Deutsche Infineum GmbH&Co.KG, and Plant Manager Dr Thiemo Dunkel, emphasised: "The partnership with RheinEnergie enables us to take a decisive step towards climate-neutral production. With this investment, we are strengthening our German site sustainably, while advancing Infineum's 2030 Sustainability Ambition to cut scope 1 and 2 GHG emission intensity by 50%, marking a major milestone toward our long-term climate goals."
Strategic Significance for Both Partners
The project holds strategic importance for both companies: Infineum is strengthening the competitiveness of its German production site through the significant reduction of its CO₂ emissions. RheinEnergie is reinforcing its position as one of Germany's leading energy services providers whilst making a vital contribution to the City of Cologne's climate protection objectives.
