Affordable and Climate-Neutral: Groundbreaking for Rondorf Nord-West Residential Quarter

With a symbolic groundbreaking ceremony, the official starting signal was given for one of Cologne’s largest current urban development projects: the new residential district Rondorf Nord-West. In cooperation with the City of Cologne, AMELIS Projektentwicklungs GmbH & Co. KG – a joint venture of Aurelis Real Estate and AMAND Landentwicklungs GmbH & Co. KG – and RheinEnergie AG are developing an innovative neighborhood in southern Cologne. On about 35 hectares, approximately 1,300 housing units will be built, providing homes for around 3,000 people. Plots are expected to be ready for construction from spring 2026.

Significance for Cologne’s Urban Development

• Three city department heads attended the groundbreaking: Markus Greitemann, Andree Haack, and Ascan Egerer.
• In his speech, Andree Haack emphasized the importance of the project: "Rondorf Nord-West is a milestone for Cologne’s sustainable urban development."
• The quarter combines housing, schools, local supply facilities, and a climate-friendly energy concept.

Affordable Housing

• About 30 percent of the apartments will be publicly subsidized.
• This corresponds to more than 400 units, to be built by Sahle Wohnen GmbH starting in late 2026.
• State Secretary Daniel Sieveke praised the project as a successful example of cooperation between city, state, and private actors to create high-quality, affordable housing.

Innovative Energy Concept

• RheinEnergie AG is implementing a cold local heating network based on groundwater and heat pump technology.
• The groundwater from the Hochkirchen waterworks, with a constant temperature of 12 °C, serves as an energy source.
• Key benefits:
  • decentralized, renewable heat supply,
  • no heat losses thanks to low network temperatures,
  • significantly reduced energy demand,
  • avoidance of local CO2 emissions.
• The cold heating supply is scheduled to start at the end of 2026.
• Stephan Segbers, board member of RheinEnergie, described the system as a model with impact far beyond Cologne.

Strong Partnership

• Joachim Wieland, CEO of Aurelis, highlighted the successful cooperation between AMELIS, RheinEnergie, and the City of Cologne.
• The project is considered a model for the interplay of urban development, infrastructure planning, and sustainable energy supply.

Infrastructure and Quality of Life

• The district will include three schools, four daycare centers, a care facility, and a local supplier.
• A new light rail connection will ensure accessibility.
• Traffic-calmed areas will enhance safety and quality of life for residents.

The Rondorf Nord-West neighborhood represents a forward-looking example of how affordable housing, sustainable energy supply, and a comprehensive social infrastructure can be combined – a project with model character for the entire region.

Expansion of Solar Energy: RheinEnergie Secures Two Major Projects

RheinEnergie has received approval from the Federal Network Agency in the latest solar energy tender, marking another decisive step toward the energy transition. The company will develop two significant solar projects: a large-scale open-space installation in Cologne-Rondorf and an Agri-PV project in Kell am See, Rhineland-Palatinate. Both initiatives reflect RheinEnergie’s long-term strategy of expanding renewable energy capacity and strengthening climate-friendly electricity generation.

Largest Solar Park on Cologne City Territory

• The project in Cologne-Rondorf will become the largest solar park within Cologne’s city limits.
• With an installed peak capacity of 10.5 MWp, the facility will supply renewable electricity equivalent to the consumption of approximately 3,000 households.
• The solar park will be located on areas adjacent to the A555 federal highway, ensuring efficient land utilization.
• RheinEnergie expects the construction permit in the coming weeks, with groundbreaking scheduled for 2026.

First Agri-Photovoltaic Project

• In Kell am See, RheinEnergie is launching its first Agri-PV system, combining agriculture with renewable energy generation.
• Solar modules will be arranged in a way that allows continued farming operations on the same land.
• Benefits include:
  • Protection of crops against excessive sunlight and hail,
  • Dual use of agricultural areas,
  • Boosting the integration of sustainable energy in rural regions.
• The facility will achieve a capacity of 4.2 MWp, sufficient to supply roughly 1,190 households with electricity.
• The start of construction is also planned for 2026, following official approval.

Doubling Renewable Capacity by 2035

• Currently, RheinEnergie operates renewable plants with a total capacity of around 300 MW.
• The company’s target is to double this figure to 600 MW by 2035.
• These two new projects are central to achieving that goal and symbolize RheinEnergie’s commitment to sustainable growth.

Statements from RheinEnergie

Stephan Segbers, Chief Sales Officer and responsible for the expansion of renewable energies at RheinEnergie, emphasized:

“With the approval of these projects, we are consistently continuing our strategy to expand renewable energy generation capacities. In Cologne, we are developing the largest solar park in the city – a milestone for the local energy transition. And with the Agri-PV project in Kell am See, we are breaking new ground by harmonizing agriculture and solar energy.”

Both initiatives underscore RheinEnergie’s ambition to make Cologne and the surrounding region a leader in climate-neutral energy and to demonstrate how innovation, sustainability, and local responsibility can be successfully combined.
