Savannah Estate Sidec power station is a 105 MW coal power station in Savanne, Mauritius. It is operated by Compagnie Thermique Savannah. Based on its capacity (estimated), it can supply roughly 131k homes (estimated). It ranks #4 of 24 Mauritius power plants by installed capacity. Commissioned in 2007, it is around 19 years old — relatively modern. In context, coal supplies about 39.3% of Mauritius's electricity; the national grid averages 642 gCO₂/kWh (17.9% low-carbon) (2024).

In context: how this plant compares
At 105 MW, Savannah Estate Sidec power station is well above the median coal plant in Mauritius (70 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical monsoon climate (Köppen Am) — Southern Hemisphere, latitude 20.5°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
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 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.
