Tamala Park Landfill Gas Power Station Upgrade Project

Tamala Park Landfill Gas Power Station Upgrade Project is an electricity generation from landfill gas project located at the Tamala Park Waste Management Facility in Mindarie, approximately 35km north of the Perth CBD in Western Australia. It was registered in May 2021 and its project area size is not specified in public records.

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 mix of coastal scrub, rapidly expanding suburban developments, and major regional infrastructure like the landfill itself. The area experiences 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 and combust gas generated from both legacy and non-legacy waste. Operated by Landfill Gas & Power Pty Ltd (following a transfer from EDL Holdings in late 2023), the station boasts a 6-megawatt generation capacity, producing enough electricity to power around 6,000 homes. The gas capture system also serves as a critical component in managing odour emissions at the facility. The landfill manages household waste for nearly 850,000 people across seven local government areas and has accepted almost 10 million cubic metres of waste over 35 years. It is now approaching its projected operational closure around 2028-2029.
