Ughelli power station is a 600 MW gas power station in Delta, Nigeria. It is operated by Transcorp Power PLC [100%]. Based on its capacity (estimated), it can supply roughly 676k homes (estimated). It ranks #23 of 69 Nigeria power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. In context, gas supplies about 68.7% of Nigeria's electricity; the national grid averages 456 gCO₂/kWh (31.3% low-carbon) (2025).

In context: how this plant compares
At 600 MW, Ughelli power station is well above the median gas plant in Nigeria (501 MW). Technically it is described as OCGT. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
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 5.5°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
