TPM Development Project Design Principles

We have developed the following design principles to help guide the development of our new TPM proposal, as we make necessary trade-offs between options which otherwise comply with the TPM Guidelines.

Our goal is to develop the best TPM proposal we can, consistent with the new TPM Guidelines, the Electricity Authority’s statutory objective and any determination by the Commerce Commission under Part 4 of the Commerce Act 1986.

Dispatch Service Enhancement Project

DSE Transition Update - September 2020

Transpower and industry dispatch participants have been steadily progressing new dispatch service transitions since September 2019, and through the Covid-19 pandemic, to meet the 31 December 2020 deadline.

Four of the thirteen participants have transitioned from the legacy dispatch system (GENCO),  three with ICCP block 2 protocol and one with Webservices over ICCP. Also, one of these participants has fully decommissioned their GENCO system. Two further participants are set to transition in the next few weeks.
