Electricity pricing

We’re one part of the power supply chain. We own and maintain the local lines and cables that deliver electricity to the customers who use it. You pay your retailer for the electricity you use (and any adjustments if you generate power and feed it back into the network). 

  • About 25% of your energy bill covers our costs to invest in and maintain our network and ensure your power supply is safe and resilient now and in the future.  

  • We also pass on Transpower’s charges to you. This is the cost of getting electricity from the power stations where it’s generated to our network. This makes up about 11% of your electricity bill. 

We review our prices every year to ensure we can continue to meet electricity demand as the communities we serve continue to grow, and the way our customers use electricity changes. Currently our pricing methodology is different for our eastern and western regions, but we plan to move towards a single pricing structure and you can read our roadmap below.

Our new pricing is effective 1 April each year.

Electricity pricing reform roadmap 

Our revenue is fixed each year and we’re progressing a number of changes to how we recover it based on how customers use the network. We’re moving towards a single and simple pricing structure for most customers that aligns with the costs to invest and operate the network.
