Big Sand Draw Plant

🔥 Natural GasIndustrial Non-CHP8 MW capacity

60th largest plant in Wyoming · 6210th nationally

Big Sand Draw Plant is a natural gas power plant in Wyoming with a nameplate capacity of 8.0 MW. It generates roughly 39.3k MWh per year — enough to power about 3,747 average U.S. homes.

Its capacity factor of 56% puts it in the middle range — running steadily but not full-time. At 879 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Natural Gas plants

Natural gas plants are the workhorse of the modern grid. Combined-cycle units achieve very high efficiency and can ramp up and down quickly to balance variable renewables. They emit roughly half the CO₂ per MWh of coal and far less of other pollutants, but they still release upstream methane during fuel extraction.
