Wheeling


Some companies make use of a concept known as “wheeling”, whereby an electricity entity establishes an electricity production installation far from the site of electricity consumption but uses the national grid to transport the electricity from the production site to the location of end-use as illustrated in the figure below. These entities vary from generating companies to large consumers of electricity.  Currently 2.9TWh are being wheeled across Eskom’s network which is equivalent to 1.3% of the electricity generated by Eskom [Eskom, 2017a].
