Rockingham Landfill Gas Upgrade Project (Revoked)

Rockingham Landfill Gas Upgrade Project (Revoked) is an electricity generation from landfill gas project located at the Millar Road Landfill Facility in Baldivis, approximately 10km southeast of Rockingham in Western Australia. It was registered in June 2022 and occupies the existing footprint of the landfill facility, though the exact spatial project area is undeclared.

Landfill gas electricity generation projects involve capturing and combusting methane, a highly potent greenhouse gas naturally released by decomposing organic waste, to produce electricity. Standard requirements for an "upgrade" project involve improving or expanding an existing landfill gas collection system to capture gas from both legacy and non-legacy waste that would otherwise be freely vented or flared without energy recovery.

The surrounding Baldivis and Rockingham region is known for a mix of peri-urban residential development, market gardens, and industrial land use. The area features a Mediterranean climate with a moderate annual rainfall of approximately 654mm, and local soils are predominantly deep, highly permeable sand and limestone typical of the Swan Coastal Plain's Spearwood Dune System.

Operated by LMS Energy Pty Ltd, the site has a long history of active gas management, with original gas capture infrastructure dating back to the early 2000s and the first engine commissioned in 2003. LMS Energy is a major player in this space, partnering with over 40 local councils and operating more landfill biogas projects than any other company in Australia. In June 2024, this project varied its methodology from the older 2015 Landfill Gas determination to the 2021 Electricity Generation determination to align with updated baseline and crediting standards. However, the project was ultimately revoked on March 10, 2026, under section 30 of the CFI Rule.
