Zagtouli — Burkina Faso

Zagtouli is a 50 MW solar power plant in Centre, Burkina Faso. It is operated by Cegelec. Based on its capacity (estimated), it can supply roughly 21k homes (estimated). It ranks #5 of 9 Burkina Faso power plants by installed capacity. Commissioned in 2017, it is around 9 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 6.5% of Burkina Faso's electricity; the national grid averages 562 gCO₂/kWh (17.2% low-carbon) (2024).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 50 MW for Zagtouli solar farm, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Data provenance

Source of the capacity and fuel values:

capacity: GEM · 2026 · L100000800356; fuel: WRI GPPD

In context: how this plant compares

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.

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

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 12.3°N — 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.

Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 2.5% 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.

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.
