ENERGY TRANSITION

Enermap, a platform that reveals the energy potential of local territories

By ENGIE - 03 February 2026 - 10:39

The energy transition starts locally. That’s why ENGIE has launched Enermap, a free, open-access website that provides a neutral, well-documented overview of each municipality’s renewable energy potential.

 

 

What need does Enermap address?

Local territories are at the heart of the energy transition. By leveraging their assets and land, they can produce local, sustainable energy, renovate public buildings, and adapt public spaces to climate challenges.

For local authorities, developing a renewable energy project (whether solar, wind, hydropower, biogas, batteries, or a heating or cooling network) is not straightforward. Elected officials, who are not energy specialists, do not always know where the potential lies.

Enermap was designed as a decision-support tool, providing clear, visual, and educational information to help them make informed choices—and explain those choices.

 

Who can access Enermap?

The platform is free and open to everyone: local authorities, citizens, associations, academics, researchers, and more. In French only.

 

What information does the platform provide?

Enermap allows users to compare energy consumption with local production, assess a municipality’s vulnerability to climate change, and identify what is feasible: which technologies, and where. The platform also estimates the economic and tax impacts of a proposed project.

“The idea is to help local authorities make the right choices. Our bet is that no one is better placed than a mayor to deliver infrastructure projects on a given territory.”

Thierry Raevel, Director of French Parliamentary Relations and Territories

 

Where does the data come from?

Enermap aggregates more than 25 public databases to provide a neutral, educational view of the development potential of different energy sources. Sources are systematically referenced.

Examples include: the Global Wind Atlas for wind energy; the Géorisques database for forests; “cartofriches” (industrial brownfield mapping) for solar power; Common Agricultural Policy (CAP) data for biogas; as well as data from IGN, Météo France, RTE, INRAE, and others.

 

What’s in it for local territories?

Renewable energy projects help accelerate the ecological transition, reduce local energy dependence, strengthen economic attractiveness, and optimize energy costs.

 

What financial support and economic benefits are available to local territories?

A wide range of support schemes exists for renewable energy projects, depending on the type of energy and the nature of the project. These mechanisms reduce upfront financial effort and help secure project development.

In terms of returns, while each project is unique, an average range can be identified: between €10,000 and €15,000 per year per installed MW, all taxes included (property tax, business tax, IFER). It varies depending on local tax rates.

As an example, a 20 MW wind farm can generate approximately €160,000 to €170,000 per year in IFER revenue, based on updated rates, with a substantial share allocated to local municipalities.

These revenues can help fund municipal investments (schools, sports facilities, roads), energy transition projects (building renovation, public lighting), local services, or local territories initiatives.

What’s next?

In the future, Enermap will roll out analyses at the departmental level.
