Sustainability - 19 February 2026

Major Contribution to the Energy Transition: Contract Signing Marks Landmark Ground-Mounted Solar Project for Cologne’s Industrial Sector

RheinEnergie AG (“RheinEnergie”) and Deutsche Infineum GmbH & Co.KG (“Infineum”) 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 large ground-mounted PV installations will be constructed 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 several thousand households. Through this project, Infineum is making a substantial contribution to reducing CO₂ emissions at its Cologne production site, with significant CO₂ savings compared to conventional electricity supply.

“With this installation, we are sending a powerful signal together with Infineum for the future viability of Cologne as an industrial location,” said Stephan Segbers, Board Member at RheinEnergie. “This project demonstrates how we can support local businesses in their decarbonisation efforts through renewable energy solutions.”

Dr Martin Halama, Managing Director at Infineum, and Plant Manager Dr Thiemo Dunkel, emphasised: “The partnership with RheinEnergie enables us to take a decisive step towards a significant step on our decarbonisation pathway at the Cologne site With this investment, we are strengthening our German site sustainably while advancing Infineum’s 2030 scope 1 and 2 GHG emission reduction ambitions, 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.

“Together with Infineum, we are building a genuine flagship project with exemplary character, demonstrating that ambitious climate protection goals and commercial interests can go hand in hand,” explains Emil Issagholian, Head of Energy Services and District Heating at RheinEnergie. “Our ‘next energy solutions’ division offers tailored energy solutions for industry and property sectors nationwide. Thanks to such full-service contracting partnerships, the energy transition in industry becomes both economically viable and technically feasible.”
