(a) Pricing structures and methods for this period are being reviewed by the Economic Regulation Authority ( ERA ) via the Access Arrangement process. The ERA’s final decision on the fifth Access Arrangement 2022-27 ( AA5 ) is due to be published by 31 March 2023. Under the Access Arrangement the ERA also approves Western Power’s tariff price list annually.
(b) The updated streetlight tariff referred to as RT9 will have the following components:
· a fixed use of system charge which is payable each day;
· a variable use of system charge calculated by multiplying the energy price by the estimated quantity of electricity consumed at an exit point (expressed in kWh and is based on the lamp wattage and illumination period); and
· a fixed asset charge based on the type of streetlight asset supplied
The streetlight tariff prices are still to be determined. Western Power will submit the 2024 price list for all tariffs based on the AA5 final decision to the ERA for review in mid-April 2023.
(c) N/A
(d) The current target for replacement of existing streetlights with light emitting diode ( LED ) is for all streetlights to be replaced with LED by 2029.
