Pedler Creek Landfill Gas Upgrade Project

Pedler Creek Landfill Gas Upgrade Project is an electricity generation from landfill gas project located at McLaren Vale, approximately 35km south of Adelaide in South Australia. It was registered in February 2017 and covers an unknown area, as it operates within the specific footprint of the Southern Region Waste Resource Authority (SRWRA) landfill site.

Electricity generation from landfill gas projects involve capturing methane, a potent greenhouse gas emitted by decomposing organic matter, and destroying it through combustion. Standard requirements include operating active gas extraction infrastructure, maintaining flares or engines to generate electricity for the grid, and strictly monitoring gas flow rates and methane concentrations.

The McLaren Vale area is famous for its intensive viticulture (vineyards) and mixed agriculture. The region experiences a Mediterranean climate with moderate winter rainfall, and the soils generally consist of red-brown earths, clay loams, and sandy loams over clay.

This project involves upgrading an existing landfill gas collection system to capture and combust gas generated from both legacy and non-legacy waste. In February 2022, the project varied its method from the 2015 Landfill Gas rules to the 2021 Electricity Generation from Landfill Gas methodology. Notably, in July 2020, the Clean Energy Regulator required the proponent, LMS Energy Pty Ltd, to relinquish 78,685 Australian Carbon Credit Units (ACCUs) due to a self-identified adjustment. The landfill has since evolved into a broader green energy precinct, with LMS Energy installing a solar farm over the capped sections of the landfill to complement the biogas generation.
