Geregu II power station is a 1,226 MW gas power station in Koji, Nigeria. It is operated by Geregu Power PLC [100%]. Based on its capacity (estimated), it can supply roughly 1.4 million homes (estimated). It ranks #9 of 69 Nigeria power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. In context, gas supplies about 68.7% of Nigeria's electricity; the national grid averages 456 gCO₂/kWh (31.3% low-carbon) (2025).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 435 MW for Geregu I power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Data provenance
Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

In context: how this plant compares
At 1,226 MW, Geregu II power station is well above the median gas plant in Nigeria (501 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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 savanna climate (Köppen Aw) — Northern Hemisphere, latitude 7.5°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
How it compares & nearby plants
The #6 largest gas power plant of 48 in Nigeria by capacity.
Nigeria has 48 gas power plants in this dataset, together about 30,326 MW of capacity.
