Grosvenor Waste Coal Mine Gas Power Station

Grosvenor Waste Coal Mine Gas Power Station is a coal mine waste gas project located approximately 8km north of Moranbah in the Bowen Basin region of Queensland. Registered in August 2015 by EDL Projects (Australia) Pty Ltd, the project operates in conjunction with Anglo American’s Grosvenor underground metallurgical coal mine. The facility captures methane-rich gas, which is naturally released during coal extraction and would otherwise be vented or flared, and utilises it to generate electricity.

This project operates under the Carbon Credits (Carbon Farming Initiative, Coal Mine Waste Gas) Methodology Determination 2015. This methodology credits the destruction of the methane component of coal mine waste gas, a potent greenhouse gas. By capturing this gas and feeding it into electricity production devices (specifically GE Jenbacher generator sets), the project achieves abatement in two ways: by converting methane into less potent carbon dioxide during combustion and by displacing electricity that would otherwise be drawn from the grid, which is typically supplied by more carbon-intensive fossil fuel sources.

The Moranbah region is the heart of Queensland's coal mining industry, though the surrounding land use also supports extensive cattle grazing. The environment is classified as semi-arid to sub-tropical with a distinct summer-dominant rainfall pattern, averaging approximately 600mm annually. The local terrain is characterized by the flat to undulating plains of the Isaac River catchment, featuring heavy cracking clay soils (vertosols) typical of the Brigalow Belt, which are fertile but prone to distinct shrinking and swelling cycles.

The project initially involved the construction of a 21MW power station (Grosvenor 1), which was later expanded with an additional 15MW capacity (Grosvenor 2). A notable development occurred in March 2025 when the project underwent a methodology variation to Compilation No. 3 of the determination. The project successfully completed its primary carbon abatement contract (CAC102147) in July 2024, having delivered over 540,000 Australian Carbon Credit Units (ACCUs) to the Commonwealth.
