Redclyffe 220kV switchyard resilience
Transpower have notified us of their intention to plan a major capex project at its Redclyffe substation.
This potential investment has been identified by Transpower as the Redclyffe substation is prone to flooding, similar to that during Cyclone Gabrielle on 14 February 2023, which lead to interruption to power supply in the greater Hawke’s Bay region.
On 22 May 2025, Transpower and the Commission agreed to a consultation programme, and timeframes for the submission and consideration of major capex proposal.
On 12 June 2025, Transpower submitted to the Commission, its proposal for Redclyffe 220kV switchyard resilience major capex project.
