ElectroNet is proud to be designing and delivering five new transportable Traction Substations for KiwiRail’s Wellington Metro Network.
Each substation will house 11 kV (AC) switchgear, a 2.5MVA transformer, a rectifier and 1500V (DC) switchgear.
Starting with the pilot site, we’ve moved from bespoke, one-off engineering to a modular, repeatable approach, with the buildings constructed by our trusted partners Brightwater & Coldstore in Greymouth, then electrically fitted and pre-commissioned by ElectroNet Services in Nelson before being transported to sites across Wellington.
It’s a pretty impressive journey for a building that starts life in Greymouth and ends up helping keep Wellington’s trains moving.
ElectroNet Consulting completed the electrical design, working alongside EDC - Engineering Design Consultants Ltd on structural design, Dalman Architects for architectural and Aurecon for heating and cooling design.
Come along to EEA 2026 to hear the full story behind this proven template for building electrical infrastructure at scale.

You can also hear directly from KiwiRail about the Wellington Metro upgrade and the role these five new substations will play in enabling faster, more frequent services.
