France, a mature gas market

Réseau de distribution : 77% de la population desservie / 9 461communes

9 500 municipalities connected (77% of population)

GrDF represents 97% of distributed gas

Primary demand : 41 Mtep / year

2 TSOs

GrDF, a world gas distribution leader

GrDF, a driving force for biomethane sucess

Injection scheme : who does what ?

Injection : distribution of roles

PRODUCER : production and purification

GAS SUPPLIER : purchase biomethane to the producer

GrDF : connection, injection and transport

- Odorization

- Continuous gas quality control

- Metering

- Pressure regulation

– Builds the connection of the production installation to the grid (charged at cost).

– Owns the installation of injection and offer to the producer a service of injection for a annual cost of 67 to 74 k€ including investment, operation, maintenance

– Operates additionnal ponctual controls of gas quality (2,5 k€/control – 10 for the 1rst year)

France potential is tremendous essentialy

due to agricultural sector

• Biogas technical potential above 200 TWh / year

• Focused on agricultural secort with 170 TWh / year

• An economic potential around 60 TWh in present conditions
