Let's talk about your project!

EDF - Bazacle à Toulouse

Renewable energies

The Energy Master Plan (SDE): this is the roadmap for understanding energy production and consumption and planning for their evolution at regional level up to 2030 and 2050.

-20%energy consumption


32%of renewables within the energy supply mix


-40%greenhouse gas emissions


Priority actions:

  • Renewing the energy supply for housing
  • New-build housing for the residential sector with improved energy performance and the standardised implementation of "Energy Producing Buildings" (photovoltaic panels & energy efficient decarbonised heating equipment)
Toulouse, parc solaire à l'Oncopole

Solar energy

The development of photovoltaic solar energy and the existing installations in the metropolitan area: 

  • Inauguration at the end of 2021 of the largest urban photovoltaic plant in France: 35,000 panels (15 MW on 25 ha) on the Oncopole site.
  • This produces the annual equivalent of the electricity consumption of 4,100 inhabitants​
    • Main projects for the metropolitan area :
    • The Plaine de l’Oncopole > 15 MWc
    • The MEETT Exhibition Centre > 5 MWc
    • The Market of National Interest > 1,7 MWc
    • The Castelginest wastewater treatment plant > 0,3 MWc

Toulouse Metropole’s heating networks

  • This involves heat produced by the combustion of non-recyclable waste that is fed back into the heating network.
  • Toulouse Metropole operates 3 heating networks under public service contracts.
  • On average, more than 90% of them are powered by renewable or recovered energy (EnRR).
Toulouse, usine hydro-électrique de EDF-Bazacle


Toulouse has 3 hydroelectric power stations which are mainly used for urban lighting; one on the Ile du Ramier, a second at Bazacle and a third at La Cavaletade which alone produces 7 MWh/year (i.e. the consumption of 1,000 homes).

Toulouse, usine de méthanisation du Ginestous

The Le Ginestous methanisation plant

Slurry from the wastewater treatment process is recovered to produce biogas (bio methane = green methane) which is also fed into the general energy grid.

  • 28 million Euros of investment
  • 1Nm3 of bio methane = 10,7 KWh
  • 10,000 tonnes of CO2/year prevented (4,700 cars per month or the total CO2 absorption capacity of 300,000 trees)
  • It is the largest urban factory in France

Competitiveness Clusters and hubs within the sector

The DERBI hub: created in 2005, the DERBI competitiveness cluster brings together companies, laboratories, universities, training centres, professional federations, financial organisations and local authorities involved in the growth of the renewable energy sector.

  • 350 members
  • 336 projects listed since 2006, including 197 that have already received funding

CEMATER: a cluster bringing together professionals in the renewable energy and sustainable construction sector in the Occitanie region. (>90 members)

Aqua Valley: federates a network of 230 members (large companies, small and medium-sized businesses, research and training organisations, associations) mainly located in the Occitanie / Pyrénées-Méditerranée and Provence-Alpes-Côte-d'Azur regions.
Their expertise and know-how cover all aspects of the water cycle.

Focus on hydrogen

Project Hyport (Q4 2022)

Created by ENGIE Solutions (51%) and the Occitanie Regional Climate and Energy Agency (49 %), in late 2022 Hyport will inaugurate its first green hydrogen production plant (430 kg/day) that will supply 180 light vehicles and 7 busses at the Toulouse Blagnac Airport site. Toulouse’s airport is the first airport in Europe to boast a facility for the renewable supply of hydrogen to power shuttle busses that transport passengers on site. 
1 plant near the runways at 350 bars 
1 plant near the city at 350 & 700 bars

The Francazal Hydrogen Technocampus (2024)

15,000m² are earmarked to house Europe's largest research, testing and technological innovation centre dedicated to green hydrogen. It will house so-called « low-power » and « high-power » units dedicated for use by universities, Start-ups and industries.
Total investment (initial funding and equipment): €40M 
The objective is to become the largest European centre for research, testing and technological innovation dedicated to the production of hydrogen from water electrolysis.

The multi-fuel station project on the Langlade site (Tisséo)

By 2023 Tisséo Collectivités should acquire 6 to 8 hydrogen-powered buses which will be assigned to the Langlade depot for use on a regular route. Tisséo's fleet consists of 561 buses, 60% of which are hybrid, electric or run on NGV.
