New substations with separable components can be deployed in a number of configurations.
When deployed with emergency overhead lines, these substation options will have the potential to improve power restoration time by up to 12 weeks from the current state in the Hutt Valley and up to 6 weeks from the current state in the Wellington CBD.
Infrastructure will include:
- Two mobile substations ready for deployment:one in Wellington CBD and the other in the Hutt Valley region
- One 11kV mobile switchboard to enable the restoration of the electrical load at substations damaged by liquefaction and/or ground shaking.
The design will be finalised in detail over the next 6 - 12 months.
