Coal mining liberates methane gas trapped in coal seams. Waste Coal Mine Gas (WCMG) is a safety hazard and an impediment in underground coal mines. It must be extracted by mine ventilation and coal seam drainage. This extracted methane can be used as a power generation fuel. WCMG has more than 25 times the global warming potential of CO2 in the atmosphere.

Energy Developments developed and owns one of the world’s largest WCMG power generation operations at the Appin and Tower coal mines in New South Wales, Australia. This 97MW operation was completed in 1996 established Energy Developments as the world leader in WCMG power generation.
