Siba power station — Dominican Republic

Siba power station is a 210 MW gas power station in Santo Domingo, Dominican Republic. It is operated by Empresa Generadora de Electricidad Haina SA [34%]; Soluciones en Gas Natural SA. Based on its capacity (estimated), it can supply roughly 237k homes (estimated). It ranks #9 of 30 Dominican Republic power plants by installed capacity. Commissioned in 2023, it is around 3 years old — recently built. In context, gas supplies about 26.8% of Dominican Republic's electricity; the national grid averages 537 gCO₂/kWh (23.8% low-carbon) (2025).

In context: how this plant compares

At 210 MW, Siba power station is around the median gas plant in Dominican Republic (210 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.

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 18.5°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), 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.
