Bunya Landfill Gas Project

Bunya Landfill Gas Project is an electricity generation from landfill gas project located at the Bunya Waste Management Facility, approximately 15km northwest of Brisbane's central business district in the Moreton Bay region of Queensland. It was registered in April 2014 and covers a highly localized area restricted to the footprint of the landfill facility.

Electricity generation from landfill gas projects involve capturing methane emissions produced by decomposing organic matter (both legacy and non-legacy waste) and combusting them to generate renewable electricity. By doing so, the methodology prevents methane, a greenhouse gas significantly more potent than carbon dioxide, from freely venting into the atmosphere while generating usable power.

The Moreton Bay region surrounding the facility is characterized by a mix of peri-urban acreages, residential suburbs, and natural bushland. The region experiences a subtropical climate with relatively high rainfall. Local soils typically consist of clays and loams, which are heavily utilized and compacted on-site to provide the necessary capping and structural lining required for effective modern landfill management.

This project has continuously evolved through a long-term partnership between the proponent, Moreton Bay Regional Council, and their agent LGI Limited. Initially operating to capture and flare methane, the facility was upgraded to a renewable power station in 2018. In a pioneering, world-first move in 2024, LGI installed a 1MW/2MWh Tesla Megapack Battery Energy Storage System (BESS). This allowed the project to operate as a renewable hybrid, capable of storing landfill-generated power and dispatching it to the local grid within seconds to manage voltage stability. Additionally, the project transitioned methods multiple times to maximize efficiency and successfully completed a major carbon abatement contract (CAC752641) with the Commonwealth in May 2022, delivering over 313,410 tonnes of abatement.
