According to Eskom's Acting Chairperson of the Board, Mr Makwana, Eskom's performance for the year under review has been that of ensuring that South Africa's lights were on. Some of the utility's targets for the year included efforts to rebuild coal stocks, intensify maintenance, increase generation and moderate demand. The results have been the stability of electricity supply to the public at large. However, the reserve margin is still very constrained and that power conservation is still absolutely crucial.
