Coal hits new low as NEM demand continues to fall

Coal hits new low as NEM demand continues to fall

The latest Cedex report finds the total amount of electricity supplied by Australia’s coal-fired generators at its lowest level in the history of the NEM. But while the report links the introduction of the carbon price to falling emissions and rising renewables output, the reduced demand for coal looks more like the new normal.
