The unit will be shut down by the middle of December, but will operate during the summer months from June to September. The other two coal units at Martin Lake will continue to operate year-round.
Luminant plans to partially suspend commercial operations at three coal-fired units – a capacity of 1,880 MW – in this fashion. The mothballed plants would require a few weeks or months to get ready for a return to service.
Luminant is the power generation arm of Energy Future Holdings.
