Energy and Supply in Leverkusen: Between Climate Protection, Budget Pressure, and Digitization

Energy and Supply in Leverkusen: Between Climate Protection, Budget Pressure, and Digitization

The city of Leverkusen is navigating a complex balancing act: On one side lies the necessity to meet climate protection goals and increase energy efficiency, while on the other side is the reality of an overburdened budget that has been in deficit for several years. In February 2026, numerous decisions were made that will shape the city's future energy and supply structure—both technologically and financially.

Renewable Energy and Heating Planning: Between Regulations and Reality

Leverkusen is under obligation: Since 2024, municipal heating planning has been a legal requirement. Following the completion of the status and potential analysis in November 2025, the city is now in the final phase of planning. The public information event on February 26, 2026, marks a milestone—it aims to inform the population about the planned measures and to gather feedback. The final report is scheduled for May 2026 and will then be submitted to the City Council for approval.

Progress is also being made at the regional level: The substantive sub-plan for Renewable Energy for the Cologne administrative district has been legally confirmed. However, Leverkusen itself will not develop wind energy areas due to a lack of space. Instead, the city is focusing on photovoltaics and local heating systems. A central point here is the obligation under § 1 Abs. 2 of the NRW Sanitation Ordinance (SAN-VO NRW) to assess photovoltaic systems during renovation measures.

Waste Management and Material Recovery Islands: Structural Challenges

The waste management situation in Leverkusen remains problematic. Approximately 41 of the material recovery islands are regularly contaminated with bulky waste, leading to increasing cleaning and emptying costs. Although 21 of these sites can accept electrical and electronic waste, the detection of illegal dumping remains vulnerable. Between 2021 and 2025, 44 penalty proceedings were initiated—an indicator of the ongoing challenges.

The city therefore plans to introduce so-called "disposal hubs": barrier-free underground containers with fill-level sensors to reduce CO₂ emissions and minimize visual pollution. However, video surveillance will be omitted to address privacy concerns. In the long term, the goal is to improve the detection of deficiencies and implement coordinated cleaning measures.

Climate Protection and Flood Protection: Digitization as a Key

Another central topic is the KIRa-Berg project, which plans an integrated flood management system with AI-supported simulations. A core component of the initiative is X-band radar equipment to expand the weather service. With total costs of 1.83 million euros and a timeframe from July 2026 to December 2028, Leverkusen is relying on technology and innovation here. The project is accompanied by the Cologne University of Applied Sciences (TH Köln), which is developing a digital information platform to optimize rescue operations.

Improvements are also being made in fire water supply: Following a fire in Atzlenbach (December 9, 2025), the fire water volume was increased to 800 liters per minute. Two large fire trucks, each with a capacity of 9,000 liters, have been procured to meet the city's fire protection needs.

Budget Situation: The Pressure is Increasing

The city's financial situation remains critical. With deficits exceeding 195 million euros in 2026 and a debt level of over 900 million euros (2028), Leverkusen is on a budgetary path that is expected to rise to around 2 billion euros by 2040. The budget is only expected to balance by 2040—a clear warning to politics to implement long-term structural adjustments.

Although funds from the old debt relief (157.10 million euros) and the NRW Infrastructure Act (78.38 million euros) are flowing into the budget, the business tax will be increased to 280% starting in 2027 to generate revenues. The question is whether these measures will be sufficient to finance the long-term investment needs, particularly in the areas of energy efficiency and climate protection.

Outlook: Between Course Correction and Progress

Leverkusen faces the challenge of managing multiple fronts: energy and heating planning, waste management, flood protection, and budget stabilization. The city has initiated decisive measures in recent months, but implementation remains complex. The heating plan, the digitization of waste management, and the AI-supported flood protection projects show that progress is possible—even in a city under high space and financial pressure.

In the future, it will depend on how well the city is able to balance investments and cost-saving measures. Only in this way can Leverkusen remain a model for a sustainable, energy-efficient, and climate-resilient city in the region.
