Morgan City is retired. EIA's monthly generator inventory (EIA-860M, August 2026) lists every generator at this natural gas plant as retired; the last one retired in June 2015. It is not counted among Louisiana's operating plants or in any ranking on this site.
The figures below describe the plant when it ran: equipment from EIA Form 860 (2024).
The 70.3 MW is nameplate capacity: the most this plant's generators are rated to produce, not what it actually generates. EPA eGRID reports no positive net generation for it this year.
How it works
Why the numbers look like this: a boiler and turbine this size take hours to bring up from cold, so steam plants were built to run steadily for long stretches. A steam plant with a low capacity factor is usually being held in reserve, or run only through the hottest and coldest weeks.

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.
