Current grid prices 2024/25 (1 April 2024 to 31 March 2025)
In December 2023, we notified transmission customers of the prices under the TPM for the 2024/25 pricing year (April 2024 - March 2025).
Some transmission customers will see an increase in their costs and others will see a decrease. How transmission charges are passed on to businesses and households connected to local lines companies is not something Transpower has control or influence over. Each local lines company decides how to pass these charges on to their consumers, taking into account guidance provided by the Electricity Authority. Transmission charges typically make up 8-10% of the average consumer’s total power bill.
