NEW ZEALAND GAZETTE
4677
2.3 The charges for Trans Power have five components which are:
(a) Connection charge
(b) Capacity charge
(c) Network charge
(d) South Island differential charge
(e) Revenue neutral charge.
2.4 The above charges have been allocated across the customers per each individual point of supply. Monowai’s costs have been allocated on the basis of avoided Winton charges.
2.5 The allocation of the transmission charges among the customers is based on the Winter Demand, Winter Day Energy, Winter Peak Energy and Total Energy.
2.6 For the largest customers the charges were individually assessed on their respective profiles, but for all the other customers the charges were allocated on the basis of load group profiles.
2.7 A winter after diversity maximum demand factor is used which is the ratio between the summated individual winter maximum demands of the large customers and the various groups, and the overall winter peak maximum demand for the two individual networks.
- SUBTRANSMISSION CHARGES
3.1 THE POWER COMPANY
3.1.1 The subtransmission network was divided up into its constituent components including every line and every zone substation. These components were categorised, ie 66,000 or 33,000V, indoor and outdoor, size, number of transformers, circuit breakers, length of line etc.
3.1.2 All the values were based on the replacement value costs and these values were then split into two components:
(a) The basic assets required to supply customers, and
(b) The incremental value of the extra capacity required to provide a back-up supply to other customers.
3.1.3 These values were then amended by the ratio of the overall replacement cost : asset value for the network and then their share of the use charge payable to the shareholder was calculated.
3.1.4 Each Network component was then selected and the groups of customers who benefited from each individual component were identified and divided into the class of benefit, ie whether they benefit as the normal method of supply or whether they benefit from it as a backup supply.
3.1.5 The allocation of the subtransmission supply charges among the customers is based on the Winter Demand, Winter Day Energy, Winter Peak Energy and Total Energy.
