Tamala Park Landfill Gas Power Station Upgrade Project

Tamala Park Landfill Gas Power Station Upgrade Project is a waste-to-energy project located in the northern Perth suburb of Mindarie, approximately 35km north of the Perth CBD in Western Australia. It was registered in May 2021 and covers an unknown project area size. The site operates within the Tamala Park Waste Management Facility, a major regional landfill situated amidst the coastal scrub and rapidly expanding suburban developments of the Swan Coastal Plain.

Electricity generation from landfill gas projects involve capturing methane, a potent greenhouse gas released during the decomposition of organic waste, and combusting it to generate electricity. Under this methodology, developers are credited for upgrading and maintaining gas collection networks to convert methane into less potent carbon dioxide. The generated electricity is then fed into the local grid, displacing fossil-fuel-based power.

The Swan Coastal Plain region features a Mediterranean climate, characterized by hot, dry summers and mild, wet winters. The soils in this coastal area are generally sandy, specifically belonging to the Spearwood and Quindalup dune systems.

This project upgrades an existing landfill gas collection system to capture gas from both legacy and non-legacy waste. Operated by Energy Developments (EDL) through the proponent Landfill Gas & Power Pty Ltd, the station boasts a 6-megawatt generation capacity, producing enough electricity to power around 6,000 homes. The gas capture system is also a critical component in managing odour emissions at the facility, which has been the subject of significant community interest as the landfill approaches its projected operational closure around 2028-2029. The project's methodology was updated in 2022 to the 2021 Landfill Gas generation rules, and the participant name was formally transferred from EDL Holdings (Australia) Pty Ltd to Landfill Gas & Power Pty Ltd in late 2023.
