Grosvenor

EDL owns and operates the 21MW Grosvenor 1 and 15MW Grosvenor 2 Power Stations. The stations are fuelled through the capture and combustion of waste coal mine gas, which is converted to electricity for the national electricity market.

About the WCMG power station

EDL negotiated gas supply and connection agreements with Anglo American to develop and build the 21 MW Grosvenor Power Station in 2015. These agreements were updated in 2017 to include a 15MW  expansion at Grosvenor 2.

This would be the third time EDL has built and operated such a structure on an Anglo site with one Grasstree Mine and two at Moranbah Mine.

WCMG is produced during coal mining as methane gas trapped in coal seams is released. As this product can be a safety hazard and a challenge to mining operations, it is extracted by mine ventilation and coal seam drainage.

Historically a waste product that is vented or flared, the extracted methane is used by EDL as a power generation fuel—displacing grid electricity and delivering reliable, and affordable energy which significantly reduces greenhouse gas emissions.

Each power station connects to the Anglo 66kV electricity network via a dedicated overhead powerline that was designed and constructed as part of the Grosvenor 1 Project. Both power stations export electricity using twelve 3MW Jenbacher J620 generator sets,  seven installed at Grosvenor 1 and five at Grosvenor 2.
