What makes up MainPower's billing?

Your electricity bill is made up of several elements, one of which is the cost of delivering electricity to your property via MainPower’s network, a process known as distribution. The distribution charge accounts for around 27% of your total electricity bill and is made up of a combination of fixed and variable charges.

MainPower is also charged by Transpower for the costs of transmitting electricity from the electricity generators through the national grid to the MainPower network. We are required by the Commerce Commission to pass these charges through to consumers in our pricing. Transmission charges account for approximately 10% of your total electricity bill.
