Successfully overcoming the challenges of heat planning

Legally compliant

With experience gathered from over 500 projects, we align our approach consistently with the current statutory frameworks (Heat Planning Act – WPG).

Methodological depth

We deliver engineering precision in potential analysis. Based on real-world data – ensuring your planning withstands the practical realities of later implementation.

Political viability

Our moderators engage the public and stakeholders at an early stage – through moderated in-person formats and digital participation concepts.

The path to your heat plan

01

Suitability assessment & inventory analysis

Automated integration of heterogeneous real-world data (ALKIS, chimney sweep data, etc.) for building-specific analysis without manual effort.

02

Potential analysis

GIS-based identification of local renewable energy sources and waste heat potential, taking into account local planning restrictions.

03

Target scenarios

Development of realistic scenarios for a climate-neutral supply infrastructure by 2045 and definition of clear suitability areas for heating networks or individual solutions.

04

Implementation strategy

Elaboration of a spatially localized catalog of measures, which is immediately available in the Digital Twin for follow-up projects (e.g., BEW studies).

05

Municipal heat plan

Finalization of the heat plan according to the WPG and technical support up to the official council resolution.

Small municipalities & convois: Efficient heat planning

Tailor-made solutions for limited administrative capacities

Practical experience

Proven processes for small municipalities and inter-municipal convoys.

Flexible service modules

Our approach can be tailored precisely to your municipality and stakeholder structure.

Strategic options

We support you  in finding the optimal procedure – whether in a convoy or via the simplified procedure.

The Digital Twin

Making better decisions: Why the Digital Twin is crucial for municipal heat planning

Der Digitale Zwilling der Planungsplatform von greenventory

Interactive digital representation

The PDF report for heat planning is the required documentation – the Digital Twin is the living foundation behind it. Since the report is generated directly from this digital application, your planning becomes a dynamic tool that is intuitively accessible to you. Utilize your data in the long term for the legally mandated updates as well as follow-up projects, and continue to manage your energy transition independently.

Unified data foundation

The Digital Twin breaks down project silos: specialized departments, municipal utilities, and planners work on a unified platform instead of in isolation. The automated fusion of heterogeneous data creates a precise foundation that brings all actors in the administration and municipal utilities to the same level of knowledge, enabling robust decisions.

Acceptance through public engagement

Relevant planning content can be embedded directly into the municipal website as interactive maps – for modern communication that turns affected individuals into active participants, builds trust, and makes the heating transition tangible for citizens and stakeholders.

Expert Insights: How to succeed in heat planning

According to the Heat Planning Act (WPG), large district cities and metropolitan areas with more than 100,000 inhabitants must submit their heat plan by June 30, 2026. For all other municipalities – including small communities with fewer than 10,000 inhabitants – the deadline ends on June 30, 2028. The goal is to establish a comprehensive climate-neutral heat supply in Germany by 2045.

A roadmap to a climate-neutral heat supply by 2045 (in Baden-Württemberg and Schleswig-Holstein already by 2040). The planning provides municipalities, municipal utilities, and grid operators with a sound decision-making basis regarding:

  • which areas are likely suitable for heating networks and
  • where individual solutions (e.g., heat pumps) are the most probable option.

While the classic PDF report fulfills the legal documentation obligations, a Digital Twin makes the results of municipal heat planning permanently usable in day-to-day administrative work. Through the intelligent networking of data sources, it breaks down project silos between specialized departments, municipal utilities, and energy suppliers. This creates maximum transparency for all stakeholders and enables robust, data-driven decisions for the local heating transition. In this way, you transform your planning from a one-off inventory analysis into a dynamic tool that actively supports efficient updating and future urban development.

Acceptance is the key to success. That is why we rely on moderated participation formats and digital solutions such as interactive maps that make the planning transparent. In addition, we offer an application for digital energy consulting to draw building owners’ attention to their individual options at an early stage.

The creation of municipal heat planning in Germany is primarily funded via the Municipal Directive (KRL). Municipalities can currently expect a baseline funding rate of 60% up to 90% of total costs, with financially weak municipalities often benefiting from increased funding rates. Since the KWP became a statutory mandatory task in 2024, funding should be applied for promptly via the National Climate Initiative (NKI) to minimize the budget burden.
Check eligibility now – We support you with your application.

A simplified procedure is possible under the Heat Planning Act (WPG) for municipalities with fewer than 10,000 inhabitants. These small municipalities can either carry out the planning on a reduced scale or combine into inter-municipal convoys. This not only saves costs through joint tenders but also pools human resources for data collection and stakeholder management.
