Mmamabula Energy Project is a 3,600 MW coal power station in Central, Botswana. It is operated by Mmamabula Power Plant Development Pty Ltd [100%]. Based on its capacity (estimated), it can supply roughly 4.5 million homes (estimated). It ranks #1 of 12 Botswana power plants by installed capacity. Commissioned in 2026, it is around 0 years old — recently built. In context, coal supplies about 98.3% of Botswana's electricity; the national grid averages 851 gCO₂/kWh (0.3% low-carbon) (2024).

At 3,600 MW, Mmamabula Energy Project is well above the median coal plant in Botswana (600 MW). 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.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a hot semi-arid steppe climate (Köppen BSh) — Southern Hemisphere, latitude 23.6°S — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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 a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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 #1 largest coal power plant of 11 in Botswana by capacity.
