A power supply restriction, as a measure of last resort, follows a meticulous and consultative process between the customer and the utility. A notice, within a stipulated time frame and pursuant to the supply agreement in place between the parties, is issued to the customer. If the customer fails to honour their obligation/pay the outstanding bill within the stated time frame/grace period, the utility engages the customer to discuss modalities of the restriction, a process intended to preserve the safety of the mine and people. Restriction means a reduction in the level or amount of power a customer normally receives; it does not mean a complete cutting off of supply. The customer is always left with sufficient power for purposes of safeguarding personnel and the mine’s assets.
