✨ Electricity Distribution Pricing Methodology
4678 NEW ZEALAND GAZETTE No. 178
3.1.6 The backup charges were allocated to customers on a total kWh basis, ie it was considered that a backup supply was important 24 hours a day and more important to higher users. A ratio of 4:1 was used to differentiate the value between commercial and residential customers.
3.1.7 The maintenance costs for the subtransmission system were based on the 1995/96 estimates and proportioned out to a cost per transformer, length of line etc. These costs were then allocated to each component and for the large customers the maintenance costs are based on the actual network components used to supply them. The maintenance costs were allocated on the total kWhs on the basis that the more the customer used, the more important the maintenance of these assets was to provide a reliable supply. For customers who do not have individual charges the charges were averaged over the zone substations.
3.1.8 The above charges were applied to the larger commercial customers on an individual basis which depended on their location and profile. For all other customers the charges were averaged over each load group
3.2 ELECTRICITY INVERCARGILL LIMITED
3.2.1 All the costs were averaged over the zone substations for all customers dependant on load groups. A backup charge equivalent to 15% of the total annual charge relating to the assets was estimated and this was allocated in the ratio of 4:1 between commercial and residential customers, and as above was charged out per total kWhs.
3.2.2 The supply part of the charge was allocated on a similar basis to The Power Company subtransmission supply charges as in Clause 3.1.5.
3.2.3 The maintenance charges were also allocated in a similar method to The Power Company maintenance charges.

4.1 THE POWER COMPANY
4.1.1 Each individual 11,000V feeder was identified and its length, the number of transformers, total connected capacity etc were determined. The total kWhs for each feeder was then divided into Winter Peak kWh, Winter Day kWh, and Summer Day kWh.
4.1.2 The supply charge was allocated over the contract capacity of the installation, the Winter Peak energy, the Winter Day energy and the Summer Day energy.
4.1.3 For the non-individual costed customers, the groupings were divided on the basis of load and location. The location was based on three sectors:
(a) Urban
