70th largest plant in Indiana · 3326th nationally
Portside Energy is a natural gas power plant in Indiana with a nameplate capacity of 61.0 MW. It generates roughly 232.0k MWh per year — enough to power about 22,099 average U.S. homes.
Its capacity factor of 43% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (61.0 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

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.
