Asset management in power systems is exercised to improve network reliability to provide confidence and security for customers and asset owners. While there are well-established reliability metrics that are used to measure and manage business-as-usual disruptions, an increasing appreciation of the consequences of low-probability high-impact events means that resilience is increasingly being factored into asset management in order to provide robustness and redundancy to components and wider networks. This is particularly important for electricity systems, given that a range of other infrastructure lifelines depend upon their operation. The 2010-2011 Canterbury Earthquake Sequence provides valuable insights into electricity system criticality and resilience in the face of severe earthquake impacts. While above-ground assets are relatively easy to monitor and repair, underground assets such as cables emplaced across wide areas in the distribution network are difficult to monitor, identify faults on, and repair. This study has characterised in detail the impacts to buried electricity cables in Christchurch resulting from seismically-induced ground deformation caused primarily by liquefaction and lateral spread. Primary modes of failure include cable bending, stretching, insulation damage, joint braking and, being pulled off other equipment such as substation connections. Performance and repair data have been compiled into a detailed geospatial database, which in combination with spatial models of peak ground acceleration, peak ground velocity and ground deformation, will be used to establish rigorous relationships between seismicity and performance. These metrics will be used to inform asset owners of network performance in future earthquakes, further assess component criticality, and provide resilience metrics.
A photograph of the earthquake damage to the Canterbury Provincial Chambers Buildings on Durham Street. Large sections of the masonry have collapsed, spilling onto the road. Wire fencing has been placed around the building as a cordon. Scaffolding erected up the side of the building after the 4 September 2010 earthquake has collapsed. In the distance, a crane is parked on the street.
A photograph of a Christchurch City Council red sticker. The sticker was used by the Civil Defence after the 2010 and 2011 earthquakes to indicate that a building had been inspected and that serious structural damage had been found. The sticker states that there should be no entry to the building. It also states that 'entry may result in death or injury'.
A photograph of the earthquake damage to R&R Sport on the corner of Colombo and Tuam Streets. Most of the side wall has crumbled, exposing the wooden structure beneath.
A photograph of a sign on the door of the Christchurch City Council Building on Hereford Street. The sign reads, "EOC staff to use Worcester Street entrance".
A photograph of volunteers from the Wellington Emergency Management Office on the side of a road in Christchurch. Cracks and liquefaction can be seen at the entrance to a property.
A photograph of earthquake damage to a road in Christchurch. A hole has been filled with gravel, and a road cone placed on top. In the background, cracks and liquefaction can be seen.
A photograph of rubble from a block of demolished shops on the corner of Cranford and Westminster Streets. Wire fencing and road cones have been placed around the rubble as a cordon.
