The plant consists of three units. Unit 1 was commissioned in 1977, Unit 2 in 1978, and Unit 3 in 1979. All three, when first activated, each unit had a capacity of 750 MW.[3][4][5] Plans for a fourth, 858 MW coal unit at Martin Lake was formally cancelled in 1986.[5][6] A man-made lake was created for the plant's cooling source.[7] Martin Lake was retrofitted with selective catalytic reduction (SCR) systems by Fluor in 2008 to reduce nitrogen oxide (NOx) emissions.[8][9]
Martin Lake receives its energy from nearby lignite mines and coal from the Powder River Basin in Wyoming.[2] Martin Lake used to receive lignite from the Oak Hill and Beckville Mines in nearby Rusk and Panola Counties until their closures.[10]
One of Martin Lake's units was idled in September 2013 due to low electricity prices.[11] The unit was restarted in March 2014 as electricity prices rose during the 2014 North American cold wave.[12]
