Aboadze Rotan power station is a 660 MW gas power station in Western, Ghana. It is operated by Rotan Power Ltd [100%]. Based on its capacity (estimated), it can supply roughly 743k homes (estimated). It ranks #5 of 15 Ghana power plants by installed capacity. In context, gas supplies about 61.4% of Ghana's electricity; the national grid averages 469 gCO₂/kWh (36.2% low-carbon) (2024).

At 660 MW, Aboadze Rotan power station is well above the median gas plant in Ghana (330 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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 savanna climate (Köppen Aw) — Northern Hemisphere, latitude 5.0°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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 #2 largest gas power plant of 9 in Ghana by capacity.
Ghana has 9 gas power plants in this dataset, together about 3,885 MW of capacity.
