CT TUCUMAN — Argentina

CT TUCUMAN is a 438 MW gas power station in Tucuman, Argentina. It is operated by YPF ENERGIA ELECTRICA S.A.. Based on its capacity (estimated), it can supply roughly 493k homes (estimated). It ranks #34 of 275 Argentina power plants by installed capacity. Commissioned in 1998, it is around 28 years old — long-established. In context, gas supplies about 52.7% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 1,302 MW for Tucumán power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares

At 438 MW, CT TUCUMAN is well above the median gas plant in Argentina (125 MW). 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.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Southern Hemisphere, latitude 27.0°S — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 82% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 20/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~4% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
