(a) The tariffs of the NPA are calculated on the basis of a comprehensive Tariff Methodology based on the widely used internationally best practice Required Revenue approach. The current tariff decision is based on the third tariff methodology published by the Regulator having been aproved and published in March 2017 after a number of rounds of public consultation. See annexure A: Port Tariff Methodology For Tariff Years 2018/19 – 2020/21
The tariff strategy published in July 2015 sets out a transparent and rational approach to an efficient and cost reflective pricing structure. Long term tariff targets are published on an annual basis to increase transparency and stability in the sector and significant progress have been made in the rebalancing of port tariffs on a sustainable basis. The tariff strategy is fairly unique as very few port pricing systems are publicly regulated but does reflect an advanced approach to port infrastructure pricing. Please see Annexure B: Tariff Strategy for the South African Ports System 2015/16.
