Strengthening 91 substation buildings to 67% of the New Building Standard (NBS).
Lessons from past events have led Wellington Electricity to further increase strengthening standards for earthquake-risk buildings to ensure that all of our key buildings in our network, including zone substations and other major switching stations, are raised to 67% of the NBS.
As at 31 December 2020, 70 substation buildings will be seismically strengthened. Strengthening substation buildings will:
- Protect the public and workers who operate around and maintain the equipment
- Make it easier and safer to access equipment, which will speed up the restoration of power
- Help equipment to withstand a major earthquake.
