Berlin Senate Accused of Hindering Climate-Neutral Local Heating Efforts
Berlin, May 11, 2026: The Berlin Senate is poised to present its initial draft for a city-wide heating plan by the end of June, with a clear emphasis on expanding district heating. However, this strategy is facing significant opposition from the Charlottenburg-Wilmersdorf district, the Berlin Tenants’ Association, and BUND Berlin, who are collectively advocating for a stronger focus on local neighborhood heating networks powered by renewable energy sources.
A Question of Cost and Climate Efficacy
A recent expert opinion, commissioned by the Charlottenburg-Wilmersdorf district and conducted by RWTH Aachen University, meticulously compared eight different heating supply options for the Klausenerplatz area in Charlottenburg. The findings are stark: the district heating solution, championed by the Senate, emerged as one of the most expensive options for this specific urban quarter, while simultaneously offering fewer carbon dioxide savings than alternative approaches.
Conversely, the study highlights the considerable potential of local renewable energy sources such as geothermal, wastewater heat, and solar thermal energy, even within densely populated inner-city areas like Klausenerplatz. The RWTH Aachen report unequivocally demonstrates that renewable neighborhood heating networks are not only technically feasible and more climate-friendly but, in some cases, also more cost-effective than traditional district heating. These conclusions, according to the District Office, are broadly applicable to other areas across Berlin.
In response, the Berlin Tenants’ Association, BUND Berlin, and the District Office have submitted formal statements, urging the Senate to systematically integrate decentralized and renewable heating solutions into its planning. They caution against an over-reliance on centralized district heating, which they argue could lead to new dependencies on fossil fuels and imported raw materials. Achieving a socially equitable and climate-neutral heat supply, they contend, is only possible through a more robust commitment to local, renewable energy sources.
Expert Voices: “Hindering Citizen Energy Solutions”
Daniel Buchholz, environmental expert and board member of BUND Berlin, did not mince words: “Instead of actively supporting citizen energy and cooperative heating solutions in the districts, the Berlin Senate is hindering them with all its might. With its new heating plan, it is unilaterally relying on district heating and fossil-fueled large power plants. This harms Berlin’s climate goals and makes us dependent on expensive oil and gas imports from crisis regions for many years to come.”
Buchholz further emphasized the need for secure and climate-neutral heat supply in neighborhoods, warning that otherwise, Berlin’s tenants would bear the brunt of exploding heating costs. He concluded by stating that “energy saving and renewable energies are the future, also in Berlin’s districts. Public buildings and state-owned housing estates are the ideal anchors for decentralized heating solutions; the Berlin Senate must finally seize this opportunity.”
Tenant Concerns: “Tenants Pay the Price, But Cannot Co-Decide”
Sebastian Bartels, Managing Director of the Berlin Tenants’ Association e.V. (BMV), underscored the financial burden on residents: “Tenants ultimately pay the price, but cannot co-decide. Therefore, it is all the more important for them to find out which type of heating is the cheapest for their apartment.”
Bartels highlighted the significant price difference between district heating, which still relies heavily on fossil fuels (up to 70%), and alternative solutions like “cold” neighborhood heating derived from wastewater, data centers, solar energy, or shallow geothermal energy, boosted by local heat pumps. He cited a potential annual saving of several hundred euros for tenants, emphasizing that “there is much to suggest that local heating networks can be cheaper than district heating for tenants in individual cases and with clever planning in the medium and long term.” The BMV calls for greater transparency from the state-owned Berlin Energie und Wärme BEW GmbH regarding its expansion plans and alternatives, and urges the Senate to establish a task force to mediate conflicts between neighborhood and district heating concepts.
District’s Perspective: “Endangering Berlin’s Climate Goals”
Oliver Schruoffeneger, Charlottenburg-Wilmersdorf District Councillor for Public Order, Environment, Roads, and Green Spaces, echoed the concerns: “The Berlin Senate’s heating plan unilaterally relies on the district heating of the state-owned BEW. It remains unclear how the highly centralized district heating network, which relies on combustion processes, can become independent of expensive energy imports. The Senate’s heating plan not only endangers Berlin’s climate goals.”
Schruoffeneger warned that the price explosions of fossil fuels, exacerbated by geopolitical events, would inevitably drive up district heating costs, with Berlin’s tenants bearing the burden. He highlighted the untapped potential of shallow geothermal energy in inner-city areas, alongside heat from wastewater, data centers, solar thermal systems, and waterways, to feed neighborhood heating networks. These “cold” networks, he explained, allow for the combination of various sources and seasonal heat storage underground. He stressed that even minimal energy renovations of residential buildings could enable them to utilize renewable neighborhood heating. The district’s studies in the Klausenerplatz quarter have proven the technical feasibility and economic viability of renewable heating supply systems, demonstrating that a renewable neighborhood heating network is a “feasible, price-stable, competitive, and climate-friendly alternative to district heating.” The district therefore demands “opening clauses” for existing and expansion areas of district heating, to facilitate the integration of local renewable energy-based neighborhood heating networks.
A Broader Debate on Berlin’s Energy Future
The controversy surrounding Berlin’s heating plan underscores a larger debate about the city’s energy future and its commitment to climate goals. Critics argue that the Senate’s current approach, while seemingly straightforward, risks locking Berlin into a less sustainable and potentially more expensive energy infrastructure. The call for a more decentralized, community-driven approach to heating, leveraging local renewable resources, represents a fundamental challenge to the prevailing top-down strategy. The coming months, as the Senate finalizes its plan, will reveal whether these criticisms will lead to a significant re-evaluation of Berlin’s path towards climate-neutral heat supply.
