Temuka was an existing Transpower substation with original protection and 11kV circuit breakers.
NETcon performed an upgrade to the 11kV board and protection. This involved the removal of the old switchboard along with its protection panels and the installation of a new Reyrolle Pacific 11kV switchboard with SEL protection relays. A new SCADA system was also installed relaying data from the Temuka substation back to Alpine Energy's control centre.
