Thermal coal mined by BHP will no longer be burned to make electricity in Australia, after the miner quietly ended the decades long connection between its NSW mine and the nearby power stations of AGL Energy.

BHP has started dismantling the 10 kilometre conveyor belt that fed coal from its Mt Arthur mine to AGL's Bayswater and Liddell power stations, and the miner confirmed that it had stopped selling coal to the power stations altogether during fiscal 2020.
