GasCross RiverNigeria

Calabar is a 561 MW gas power station in Cross River, Nigeria. It is operated by Calabar Generation Company. Based on its capacity (estimated), it can supply roughly 631,846 homes (estimated). It ranks #5 of 13 Nigeria power plants by installed capacity. In context, gas supplies about 68.7% of Nigeria's electricity; the national grid averages 456 gCO₂/kWh (31.3% low-carbon) (2025).

~884,585 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

206,197passenger cars driven for a year
115,361homes' yearly energy use
14,743,080tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 45% load factor × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 5.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 100% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

A gas turbine here also runs ~8% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
