What's in an electricity bill?

Energy 50%

The cost of generating and providing the electricity you use. Mercury works out this part of your bill.

Transmission 9%

The cost of moving electricity over Transpower's National Grid between power stations and local lines. Your lines company tells us the cost.

GST 13%*

Just like buying groceries, GST applies to all parts of your bill.

Distribution 22%

The cost of moving electricity over from your local lines company to your property. Your lines company tells us this cost.

Metering 5%

The cost from companies that own, maintain and read electricity meters.

Other less than 1%

This covers the Electricity Authority Levy. The Electricity Authority is responsible for the operation of the electricity market.

*We add GST as a separate line item to your bill. GST makes up 13% of the total bill price which includes GST.

Any Prompt Payment Discount is shown as a separate line item on your bill and is deducted from your total bill price, subject to you paying on time.
