NZ power grid protection from coronal mass ejection
B. Pinkney made this Official Information request to Transpower New Zealand Limited
The request was successful.
From: B. Pinkney
Dear Transpower New Zealand Limited,
A coronal mass ejection can have devastating effects on power grids, which can take many years to repair all the while, New Zealanders and plunged into darkness with no access to electricity.
The chance of Earth being hit by a grid-affecting solar storm between 2012 and 2022 is 12%. After this, the risk increases by 1% for every year that passes.
Can you please provide me details on what planning and research have been undertaken or commissioned by Transpower relating to grid-related damage from solar activity and grid hardening.
Yours faithfully,
B. Pinkney
