✨ Electricity Cost Allocation
2952 NEW ZEALAND GAZETTE No. 95
For the allocation of cost group costs to system components the criteria are as follows :-
Operations and Maintenance Costs - are allocated in proportion to the asset value of each component.
Depreciation and Finance Costs - are allocated in proportion to the asset depreciation associated with each component.
Return on Assets - are allocated in proportion to the asset value of each component.
Losses - are allocated using proportions suggested in the "Guide to Derivation of Line Charges".
3.3 Secondary Allocation of Cost Group Costs to Customer Groups
For the second step of the allocation of line costs, including operations and maintenance, depreciation and finance charges and return on assets, from the system components to the load groups the allocation criteria follows those outlined in the "Guide to Derivation of Line Charges."
General 400V Lines and Plant - are allocated to all General 400V load groups, i.e. groups 1a, 1b, 1c, 2a, 2b and 2c, on the basis of estimated anytime maximum demands of each load group
Dedicated 400V Lines and Plant - are allocated directly to dedicated 400V customers, i.e. group 3
Distribution Transformers - are allocated to all 400V installations, i.e. groups 1a, 1b, 1c, 2a, 2b, 2c and 3, on the basis of estimated anytime maximum demands of each load group
General 11kV Lines and Plant - are allocated to all installations, i.e. groups 1a, 1b, 1c, 2a, 2b, 2c, 3 and 4, on the basis of estimated anytime maximum demand of each load group
Dedicated 11kV Lines and Plant - are allocated directly to dedicated 11kV customers, i.e. group 4
District Transformers - are allocated across all installations, i.e. groups 1a, 1b, 1c, 2a, 2b, 2c, 3 and 4, on the basis of estimated anytime maximum demand of each load group
Subtransmission Lines and Plant - are allocated across all installations, i.e. groups 1a, 1b, 1c, 2a, 2b, 2c, 3 and 4, on the basis of their anytime maximum demand
The anytime maximum demand of each load group has been estimated by metering samples of customers within load groups. Load profile information is available on a majority of installations in groups 3 and 4, on some installations in group 2(c) and on some domestic transformers. The individual load profiles for installations within each load group were combined to give a typical load profile for the group. The resulting ratio of maximum demand to assessed capacity was used to estimate the anytime maximum demand of the group.
