Oghareki power station is a 500 MW gas power station in Delta, Nigeria. It is operated by Ministry of Power and Energy (Delta State of Nigeria) [100%]. Based on its capacity (estimated), it can supply roughly 563k homes (estimated). It ranks #33 of 69 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).

At 500 MW, Oghareki power station is around the median gas plant in Nigeria (501 MW). Technically it is described as OCGT. Its current lifecycle status is “Announced” — so it is not yet, or no longer, generating at full output. 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.

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 5.9°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).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #25 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.
