Bunya Landfill Gas Project

Bunya Landfill Gas Project is a landfill gas electricity generation project located at the Bunya Waste Management Facility, approximately 15km northwest of Brisbane in the Moreton Bay region of Queensland. It was registered in April 2014 and operates over an unspecified area within the active waste facility.

Electricity generation from landfill gas projects involve capturing biogas (predominantly methane) emitted by decomposing organic legacy and non-legacy waste and combusting it in a generator to produce renewable electricity. Standard requirements for this methodology dictate the continuous operation of a gas collection system, precise metering of the electricity generated, and the verifiable destruction of methane to prevent it from entering the atmosphere.

The Bunya and wider Moreton Bay area is characterized by peri-urban, residential, and bushland land uses, alongside essential local infrastructure. The region experiences a subtropical climate with moderate to high summer rainfall. Soils in this coastal hinterland typically consist of texture-contrast Chromosols and Kurosols, often featuring a mix of clays and sandy loams.

This project operates through a partnership between the Moreton Bay Regional Council and LGI Limited. Originally designed to capture and flare gas, LGI upgraded the site to a renewable power station. In 2023-2024, a 1MW/2MWh Tesla Megapack Battery Energy Storage System (BESS) was integrated into the facility, transforming it into a pioneering renewable hybrid system capable of storing and dispatching power to the local grid within seconds. The project transitioned from an older revoked methodology and successfully completed a fixed-delivery carbon abatement contract with the Clean Energy Regulator in May 2022.
