Apart from a few large consumers, Unison does not directly bill consumers on our networks. We charge the electricity retailers, who bundle our charges with their other costs on consumers’ bills. Although we publish our tariffs on this website, we have no control over how retailers pass these on in consumers’ bills.
The line charges that appear on an electricity account include the costs we pass on from Transpower, for transmitting electricity from generation points around New Zealand across the national grid to ‘grid exit points’ (GXPs) in your region. The remainder of the charge covers the cost of distributing electricity from these GXPs, across our network assets to your home or business. The cost of the electricity you use is billed by your electricity retailer.
Because the electricity distribution industry is regulated by the Commerce Commission, we are required to make a range of disclosures, including pricing schedules, and our pricing methodology.
These schedules show the electricity line charges that are a component of the electricity account you will receive from your electricity retailer.
The pricing methodology disclosure sets out the methodology that Unison used to set the tariff structure and tariff rates for the pricing year. The disclosure is prepared as a requirement of the Electricity Distribution Information Disclosure Determination 2012, as well as demonstrating the extent to which the pricing methodology is consistent with the Electricity Authority’s pricing principles and disclosure guidelines.
