It was further concluded that although the amount of electricity consumption has been
fluctuating over the years, electricity costs have been escalating at an alarming rate due to
change in tariff rate, inflation and the structure of the tariff. The cost of power will increase
drastically over the next five years, due to uncertainty regarding the magnitude of the pending
Eskom tariff increases. It was recommended that mining operations must create energy
management models for their mining operations in order to reduce the amount of electricity
consumption, minimize the electricity costs and secure long term electricity supply. Models
created must be aligned to company vision, organizational structure and also operational
practice at the mine.
