GasRío NegroArgentinaCCGT · HRSG
Roca power station is a 190 MW gas power station in Río Negro, Argentina. It is operated by Tefu SA [25%]; Generación Mediterránea SA [75%]. Based on its capacity (estimated), it can supply roughly 214k homes (estimated). It ranks #62 of 275 Argentina power plants by installed capacity. Commissioned in 2018, it is around 8 years old — recently built. In context, gas supplies about 52.7% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

In context: how this plant compares
At 190 MW, Roca power station is well above the median gas plant in Argentina (125 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 cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 38.9°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 a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
