Tube mills, similar to those used in the gold mining industry, produce finer ground coal, as was well proven at Lethabo, where the calorific value of the coal is equivalent to that of a Provita biscuit. This coal is the most inferior coal used by Eskom, with an ash content of in excess of 38%, in addition to its low reactivity.

Wind Characteristics. As the wind power is proportional to the cubic wind speed, it is crucial to have detailed knowledge of the site-specific wind characteristics. Even small errors in estimation of wind speed can have large effects on the energy yield, but also lead to poor choices for turbine and site. An average wind speed is not sufficient.
