TPM Exploring a Transitional Congestion Charge

We are exploring options for any Transitional Congestion Charge (TCC) we may decide to progress as we develop our proposal for a new TPM.

Our approach

The approach we have taken is to hold two online workshops to facilitate informed discussion with invited guests, representative of the electricity industry. The guests took the opportunity to put their questions to experts from Transpower in a discussion chaired by an independent facilitator. We published the recordings and transcripts of these workshops, have invited feedback on the topics and ideas raised, and will take all this into account when we respond to the EA with a recommendation on the potential TCC option.

We believe this format provided us the best opportunity to meaningfully engage in an online environment with those who wish to discuss a potential TCC, and still make the process accessible to all. The preparatory material and recordings of the workshops are on this page below. This information has also been signposted in our weekly newsletter.

We invite feedback from anyone who is interested in providing their views on a possible TCC or responses to issues raised during the workshops.

Please send your feedback to by 5pm on 21 October 2020. We will publish any feedback we receive on 22 October 2020.

Our response

The TPM Development Project team will consider the EA’s video and published information, workshop content and any feedback when making a response and recommendation to the EA regarding a potential TCC.
