Santa Rosa is a 446.7 MW gas power station in Lima, Peru. It is operated by Edegel S.A.A.. Based on reported annual generation of 754 GWh, it can supply roughly 215k homes. It ranks #8 of 40 Peru power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. In context, gas supplies about 36.1% of Peru's electricity; the national grid averages 238 gCO₂/kWh (63.6% low-carbon) (2025).

In context: how this plant compares

At 446.7 MW, Santa Rosa is well above the median gas plant in Peru (360.8 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

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 hot desert climate (Köppen BWh) — Southern Hemisphere, latitude 12.0°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 89% 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: 17/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~3% 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 corrosive environment (estimated ISO 9223 class C4 — High), with dust abrasion the leading environmental stress.
