Tolk

⛏ CoalElectric Utility1,135 MW capacity

23rd largest plant in Texas · 265th nationally

Tolk is a coal power plant in Texas with a nameplate capacity of 1,136 MW. It generates roughly 2.7M MWh per year — enough to power about 257,868 average U.S. homes.

Its capacity factor of 27% reflects intermittent or peaking operation. At 2292 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Coal plants

Coal plants burn pulverized coal to boil water and spin steam turbines. They emit substantial CO₂, SO₂, and NOₓ along with mercury and particulate matter. Modern units include scrubbers and selective catalytic reduction; older units are increasingly being retired or converted to natural gas as economics shift.
