Compliance investigation commenced and open for participants to join

Transpower New Zealand Limited as the grid owner is alleged to have breached clause 13.141(2) when it did not change its calculation of demand information that it provided to the pricing manager after the status of Alinta ENZ Limited’s kiln co-generation plant changed to a Type B industrial co-generation station.

The alleged breach has been calculated to have caused a significant market impact with generator’s being overpaid by $31.6M and purchasers overpaying by $32.6M.

Participants who consider they are affected by the matters being investigated may join as a party to the investigation. To join the investigation participants should notify the investigator no later than Monday, 24 May 2021. The investigator’s contact details are in the notice of investigation on our website.

Transpower annual report on 10-year demand and generation forecast deferred until 31 October 2021

The annual report will be available by 31 October 2021 (normally available by 30 June).

A copy of the Gazette notice, including reasons for granting the exemption is available on our website.
