Direct Dry Cooling in the Power Sector

Matimba Power Station is the largest direct-dry-cooled station in the world, with an installed capacity of greater than 4,000MW. It makes use of closed-circuit cooling technology reducing water consumption to around 0.1 liter per kWh of electricity distributed; this, in comparison to wet cooling system power stations use 1.9 liters per kWh is a significant reduction. Driven by the need to secure water resources in the medium and long term, the Matimba example has achieved a water savings of 62,500,000m3/year.
