GridEx 2023: an exercise to test readiness

  • Distribution
  • Generation

Transpower is running its biennial GridEx simulation exercise on 14 and 15 November 2023.

GridEx simulates an emergency affecting New Zealand’s energy system, and participants work through a real-time response to a problem that has been designed to put industry and supporting agencies to the test.

Transpower is encouraging everyone across the energy industry – distributors, metering equipment providers, generators, purchasers, and retailers – to participate in, or observe, the event.

The event presents a great opportunity to gain valuable insights and lessons that can be shared widely and help inform preparations for emergency scenarios.

For more information on participating or observing, contact GridEx@Transpower.co.nz.
