5. DEVIATIONS FROM GUIDELINES

5.1 Splitting of Load Groups

  1. Load Group 1 is split into 3 load groups:-

    1a for under 5kVA
    1b for 5kVA to 14kVA
    1c for 15kVA to 28kVA

    instead of one group for up to 15kVA capacity loads supplied at 400V.
    This has been done to include all installations with less than 3 phases.

  2. Load Group 2 is split into 3 load groups:-

    2a for 29 - 69kVA
    2b for 70 - 150kVA
    2c for above 150kVA

    instead of 1 group for over 15kVA capacity loads supplied from the general 400V system. This reduces the cross-subsidisation between the higher capacity installations and the lower capacity installations.

5.2 Load Group for 11kV Installations

The 11kV installations group has been renamed Group 4 for continuity as their was no Group 4. The group has not been separated into those customers who own their own transformers and those who do not. Where the transformers are owned by Rotorua Electricity there is an additional charge per installed capacity of the transformer. This covers the return on investment and depreciation costs based on full replacement value.

5.3 Control Period Demand

The control period demand is the sum of individual average monthly maximum demands of installations within the group that occur between the hours of 7.00am and 9.00pm. As an estimate of control period demand the anytime maximum demand has been used.
