Queensland will close one of its coal-fired power stations a decade earlier than planned as the electricity grid deals with the disruption of an influx of renewable energy projects.

With federal Energy Minister Angus Taylor describing the early closure of coal-fired power stations as his "greatest fear" for the National Electricity Market, it can be revealed the 700 megawatt Callide B coal-fired power station will now close in 2028, instead of 2038-39 as originally planned.
