Stanwell wonât mothball loss-making coal units May 3, 2021 â 12.00am Save Share Queensland state-owned power company Stanwell Corporation said it wonât be mothballing any generating units from its coal-fired power stations, despite a plunge in wholesale power prices undermining their long-term financial viability. With the energy industry blindsided by the sudden departure of Stanwell chief executive Richard Van Breda last month â following comments he made about the need to transition away from coal â the company said it was still weeks away from appointing an acting CEO. Tarong Power Station, near Kingaroy, has struggled to compete with cheaper renewable energy. Energy experts predicted Stanwell would put some of its generating units in âcold storageâ as wholesale electricity fell to record lows, driven by the rapid influx of renewable energy in the middle of the day hitting the profitability of coal-fired power stations.
