Through Utilise Opunake Hydro can provide electricity to your business wherever you are in New Zealand. We also supply selected homes in Taranaki. 

Once you let us know that you’d like to go ahead with the changeover, Opunake Hydro does all the work.  You don’t need to do anything and there’s no downtime in the switchover.   Here’s how it works:

  1.       Utilise contacts your existing retailer and we agree on a date and a final meter reading.
  2.       You will receive the last bill from your existing retailer.
  3.       Utilise advises the metering and lines company that we are the new retailer for your premises. The metering company sends us the information from your meter.
  4.       Utilise sends their first bill to you.

The electricity industry in New Zealand has been designed to ensure consumers have a reliable supply of electricity. Outages are caused by a failure of the physical network ie the distribution or lines network, these outages will happen irrespective of who your electricity retailer is. The Electricity Authority information pack here explains how the physical flow of electricity and the financial markets operate independently of each other.

All electricity generators sell their power to the NZ wholesale market and all retailers buy from the wholesale market to sell to businesses and residential consumers. Electricity retailers all have access to the same electricity so you don't have to worry about your electricity provider running out of power.

The Electricity Authority has been established to provide regulatory oversight of the industry and reliability of electricity supply to all consumers and businesses in New Zealand. The EA sets prudential requirements and processes should there ever be a default in the market. These processes ensure that customers will always have a retailer and the electricity supply is uninterrupted through the process. Each retailer needs to meet the prudential requirements to be able to participate in the electricity market. This includes a ‘bond’ which is held by the clearing manager.

You don’t have to worry about contacting anyone. We will manage the entire transition for you. We will contact your existing retailer to ensure there is a smooth handover. We will also advise your metering and lines company that Utilise has become your new retailer.

The fixed daily charge is made up of the service charges that are required to deliver electricity to your business.  For example meter rental costs, meter reading, billing and also charges for lines and transmission.
