11. Landfill Gas to Power Generation Facility
Powering Waste Diversion11 I
AGL Partnership
AGL obligations
 Construct and operate the Power
Generation Facility
 Supply electricity to SAWT
AGL benefits
 Long term contract supports
capital investment
 Sell excess electricity to the
wholesale market
 Supports AGL’s commitment
to own, operate and develop
renewable energy generation
in Australia

12. SUEZ obligations
 Supply agreed minimum quantity of landfill gas
 Develop, install and maintain gas collection
infrastructure
 Purchase a minimum amount of electricity from AGL
 Maintain and operate the flare
SUEZ Benefits
 Retain control of gas collection infrastructure
 Manage environmental obligations
 Long term electricity price locked in
 Retain ownership of ACCUs created through the
destruction of methane

13. Challenges
Financial returns
- both parties
Carbon legislation changes and uncertainty
- sovereign risk
Network connections and supply
- always challenging
Reusing existing assets
- condition reports
Construction program and commissioning
Risks
Carbon legislation (repeal of RET)
Power station downtime
Supply of required gas volumes
Opportunities
Utilise waste heat from the engines to
enhance SAWT composting process
