The mine near Kosse keeps a low profi le, so much so that many longterm Limestone County residents know little about it. Recently, Steve Jenkins, community liaison for Luminant, which owns the mine, spoke at length about the facility. The Kosse mine produces a type of coal called lignite, which fuels the Oak Grove power plant. The plant has two units, both of which opened in 2010. At peak capacity, the plant can produce 1,600 megawatts of power, which is enough to support 800,000 homes in normal conditions or 320,000 homes during peak demand.
