Critical Lifelines Infrastructure - National Vulnerability Assessment Report 2020


The New Zealand Lifelines Council has just released the 2020 Edition of the New Zealand Critical Lifelines Infrastructure National Vulnerability Assessment.

The assessment provides government, industry and communities with a better understanding of:

1. What is nationally significant infrastructure; and

2. Infrastructure vulnerability and resilience to hazards.

Section 3 provides an overview of New Zealand's lifeline utility networks and critical infrastructure within those networks and provide an overview of each sector's vulnerabilities to hazards, critical customers that are dependent on its services, regulation & funding relating to resilience and current/proposed resilience investment programmes.

Resilience issues identified for the electricity sector included climate change, earthquakes, tsunamis, funding asset redundancy to improve resilience (in some regions) , the impact of changes in generation/loads (e.g. if Tiwai Point Aluminium Smelter closed) and space weather (e.g. Coronal Mass Ejections (CMEs)). It also notes the soon to be published EEA Resilience Guide for the electricity sector!
