Transpower has now delivered a proposed new Transmission Pricing Methodology (TPM) for the Electricity Authority. This is in accordance with the Transmission Pricing Methodology Guidelines, published by the Authority in June 2020, and the Electricity Industry Participation Code 2010. You can view the Electricity Authority's TPM webpages here.
We intend to publish our TPM proposal package during the week of 9 August 2021. This timing will allow the Authority the opportunity to indicate any aspects it will refer back to Transpower for consideration, which means stakeholders can assess our TPM proposal in light of the Authority's response.
