Castalia helped Vector, New Zealand’s largest electricity distribution utility, ensure that the regulatory regime made suitable provision for recovery of rebuilding costs following an earthquake, through regulatory advice to the Vector and a submission to the Commerce Commission. A series of earthquakes in Christchurch had damaged much of the electricity distribution system. The local utility requested a customized price control path to enable it to recover rebuilding costs. Vector also operates in earthquake-risk areas and wanted to be sure that precedents created after the Christchurch earthquake would be suitable if it or other distribution companies were hit by a serious earthquake.
