The closure of Southdown and Otahuhu Power stations in Auckland and the proposed closure of the Rankine units at Huntly Power Station in Waikato are expected to cause voltage management issues in the Auckland and Waikato regions as peak electricity demand increases.
To manage voltages in these regions, Transpower may need to invest in the grid or procure non-transmission solutions from third parties.
On 1 July 2016, Transpower and the Commission agreed to a consultation programme, approval timeframe and approach to considering non-Transpower solutions. These timeframes may change depending on the need for the investment.
