Oyster Creek Unit Viii

🔥 Natural GasIPP CHP497 MW capacity

98th largest plant in Texas · 746th nationally

Oyster Creek Unit Viii is a natural gas power plant in Texas with a nameplate capacity of 498 MW. It generates roughly 2.7M MWh per year — enough to power about 255,868 average U.S. homes.

Its capacity factor of 62% puts it in the middle range — running steadily but not full-time. At 710 lb CO₂/MWh, its emission rate sits below 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.
