On 3 April 2023, Transgrid provided a letter to the AER regarding its inadvertent omission of Project EnergyConnect (PEC) 'as commissioned' capex from its 2023-28 revised proposal. The correct amount was included in Transgrid's 2023-28 initial proposal and the AER's 2023-28 draft decision. For transparency purposes, we have published Transgrid's letter.
