Soyo power station is a 1,470 MW gas power station in Zaire, Angola. It is operated by Sonagás [100%]. Based on its capacity (estimated), it can supply roughly 1.7 million homes (estimated). It ranks #1 of 17 Angola power plants by installed capacity. Commissioned in 2017, it is around 9 years old — relatively modern. In context, gas supplies about 9.0% of Angola's electricity; the national grid averages 185 gCO₂/kWh (73.7% low-carbon) (2024).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 720 MW for Soyo 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 1,470 MW, Soyo power station is well above the median gas plant in Angola (132 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); GE Power. 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) — Southern Hemisphere, latitude 6.2°S — 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 an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), with marine salt corrosion 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.
