Deadline 30 June 2026. Over 30% of large cities are behind schedule.
The Heat Planning Act requires cities with over 100,000 residents to submit a heat plan by mid-2026. Implementation is complex, data-intensive and impacts thousands of property owners' decisions.
Structured assessment and implementation support.
The Challenge
Challenges for municipalities
The Heat Planning Act (WPG) mandates area-wide heat planning - the deadline for large cities is 30 June 2026.
Data foundations are often incomplete: consumption data, grid infrastructure and building stock must be systematically captured.
Residents and property owners expect clear statements on supply zones, technologies and timelines.
Skills shortages and coordination between administration, utilities and energy suppliers delay implementation.

Let's clarify in a free initial consultation whether and how we can help.
Context
Heat planning as a strategic infrastructure decision
Municipal heat planning is more than a regulatory obligation. It determines the heat supply structure for decades, influences investment decisions of property owners and defines expansion zones for district heating, hydrogen and decentralised solutions. A robust heat plan requires precise data foundations, transparent scenarios and early stakeholder engagement.
WPG: cities >100,000 residents by 30 June 2026, remaining municipalities by 30 June 2028. Funding via BEW and KfW programmes possible.
Our Approach
Our approach for municipalities
01
Assessment
Systematic capture of building stock, consumption data, grid infrastructure and existing heat sources.
02
Scenario development
Create supply scenarios with cost-benefit analysis for district heating, heat pump and hybrid solutions.
03
Zone designation
Define supply zones and prioritisation map for phased expansion.
04
Implementation support
Coordination with utilities, property owners and funding bodies. Communication strategy for those affected.
What You Receive
Structured assessment and data collection
Supply scenarios with cost-benefit analysis

What happens if you do nothing?
Risks of delayed heat planning
Missed deadline creates planning uncertainty for thousands of property owners.
Property owners make heating decisions without a robust basis - misallocation follows.
District heating expansion without a heat plan leads to suboptimal grid planning and investment gaps.
