Caniçal is a 6.6 MW solar power plant in Madeira, Portugal. It is operated by Atlantic Islands Electricity SA. Based on its capacity (estimated), it can supply roughly 2.8k homes (estimated). It ranks #259 of 480 Portugal power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 17.3% of Portugal's electricity; the national grid averages 128 gCO₂/kWh (81.0% low-carbon) (2025).

At 6.6 MW, Caniçal is well above the median solar plant in Portugal (2.3 MW). Technically it is described as PV. Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 32.8°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 77% 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: 21/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), with marine salt corrosion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #20 largest solar power plant of 72 in Portugal by capacity.
