407th largest plant in Texas · 2020th nationally
Power Island is a natural gas power plant in Texas with a nameplate capacity of 141 MW. It generates roughly 879.4k MWh per year — enough to power about 83,752 average U.S. homes.
Its capacity factor of 71% puts it in the middle range — running steadily but not full-time. At 600 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.

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.
