3. ALLOCATION OF LINE BUSINESS COSTS TO CUSTOMER GROUPS
Eight load groups have been identified for cost allocation and line charge derivation and are defined in greater detail in Appendix I). They are:-
1a General 400V Supply under 5kVA
1b General 400V Supply from 5kVA to 14kVA
1c General 400V Supply from 15kVA to 28kVA
2a General 400V Supply 29kVA to 69kVA
2b General 400V Supply 70 kVA to 149kVA
2c General 400V Supply above 150kVA
3 Dedicated 400V Supply above 100kVA
4 11kV Supply
Some costs, including operations and maintenance, depreciation and finance charges, return on line assets and losses are first allocated to system components before allocation to load groups. Other costs, including administration, transmission, meter reading, meter costs and load control are allocated directly to load groups.
3.1 Direct Allocation of Cost Group Costs to Customer Groups
For the costs that are allocated directly to load groups the criteria are the same as those recommended in the "Guide to Derivation of Line Charges" prepared by the SOLEC working party for ESANZ. They are :-
Administration Costs - are allocated equally across all metered installations
Transmission Costs - are allocated in proportion to kVA of assessed capacity
Meter Reading Costs - are allocated equally across all metered installations
Meter Costs - are allocated to different types of meters which are allocated to each load group to reflect the use each group makes of each meter type.
Load Control Costs - are allocated equally across all metered installations.
3.2 Primary Allocation of Cost Group Costs to System Components
For those costs that are first allocated to system components before allocation to load groups, the proportions for the allocation to system components are those obtained from the allocation of line assets to system components. For this allocation, where assets are clearly identifiable as belonging specifically to a system component they are allocated as such. Where assets are identifiable as belonging to more than one system component they are allocated by the proportions of assessed capacities of the system components. When it is not possible to identify an asset as belonging to a system component, or components, then the asset is allocated over all system components by the proportions of the assessed capacities of the system components.
