On 12 April 2013 we approved Transpower's proposal to increase the major capex allowance for the Otahuhu Substation Diversity project.
An equipment failure at the Otahuhu substation in June 2006 resulted in a widespread loss of supply of electricity to Auckland and Northland. Following this incident, Transpower implemented the Otahuhu Substation Diversity Project to improve the reliability of supply into Auckland and Northland.
Our 2013 decision increases Transpower's allowance for the project, as previously approved by the former Electricity Commission.
