Pedler Creek Landfill Gas Upgrade Project

The Pedler Creek Landfill Gas Upgrade Project is a landfill gas electricity generation project located at Seaford Heights, approximately 35 kilometers south of Adelaide, South Australia. Registered in February 2017 by LMS Energy Pty Ltd, the project operates within the Southern Waste Depot facility on the outskirts of the world-renowned McLaren Vale wine region.

This project operates under the Carbon Credits (Carbon Farming Initiative, Electricity Generation from Landfill Gas) Methodology Determination 2021. The methodology involves the installation and operation of gas collection systems to capture methane generated by decomposing organic waste (both legacy and non-legacy). Instead of releasing this potent greenhouse gas into the atmosphere, it is combusted in generators to produce renewable electricity, which is then supplied to the local grid.

The site is situated in a region characterized by a Mediterranean climate, featuring warm, dry summers and cool, wet winters. The surrounding landscape is a mix of peri-urban residential development and significant viticultural land use. The soil profile in this area typically consists of clay and sandy loams; however, the landfill itself relies on engineered clay liners to manage leachate and gas migration effectively.

A notable regulatory event occurred in July 2020, when LMS Energy relinquished 78,685 Australian Carbon Credit Units (ACCUs) in relation to this project following a self-identified adjustment. Furthermore, the project's methodology was varied in 2022, transitioning from the 2015 Landfill Gas determination to the 2021 Electricity Generation determination, reflecting an upgrade in operational standards or reporting frameworks.
