Penrose Control Room Replacement Project

Last updated: 14 Sep 2022

What we're doing

We need to continually operate, maintain and develop New Zealand's transmission network - the National Grid - to ensure we meet the ongoing electricity needs of New Zealanders.

We are undertaking a project to build a new control relay room at our Penrose substation site and decommission the existing building built in the 1930s. 

Why we're doing it

The original 1930s-era building was found to have significant asbestos within its construction, such that it is not able to be easily removed or remediated to allow the building to be used. Accordingly, a new control building at another area of the Penrose substation will allow us to decommission and remove the older building completely.

Will it impact on consumers?

We expect all the work to occur within our existing substation at Penrose. There may be the usual construction-related activity over the time (like noise and increased dust). There may be times of reduced security of supply to customers, when we move supply from the existing building to the new building but we do not expect any power outages.
