Two new consultations on TPM amendments

The Electricity Authority Te Mana Hiko is seeking feedback on two proposals for amending the Transmission Pricing Methodology (TPM) by 26 March 2024:

Amendments to correct issues in the new TPM

We have identified several minor issues in the TPM which require amending in order for the TPM to perform in the best interests of consumers and industry. These include:

1. Minor corrections to the TPM, such as typographical errors
2. Clarifying the continuing benefit-based investment mechanism for low-value investments and anticipatory benefit-based investments
3. Correction to the calculation of Appendix A benefit-based investment allocations for new customers
4. Correction to the funded asset component and funded rebate mechanism for connection charges.

Further clarification on amending the TPM

We propose to amend the TPM to enable the Authority to make changes to the TPM outside of the provisions outlined for minor amendments in clause 12.94A of the Electricity Industry Participation Code. This will enable us to make changes and policy improvements to the TPM in addition to issues covered by clause 12.94A.

We also propose to create a new data-sharing arrangement with Transpower to streamline TPM-related calculations.
