Transpower said it will issue further operational notices when the storm passes and either remove the grid emergency or provide additional information if the severity of the situation worsens. <\/p>\n

What is space weather? <\/p>\n

Transpower said it monitors weather in New Zealand and weather in space that can affect our power system.<\/p>\n

\u201cSpace weather is when the sun ejects plasma and other matter in Earth\u2019s direction. These coronal mass ejections [CME] are rare, and most people won\u2019t notice because our planet\u2019s magnetic field shields us from the particles.<\/p>\n

\u201cHowever, these CMEs can cause geomagnetic storms on Earth and these storms can send unwanted currents through the long electricity circuits that we manage,\u201d Transpower said. <\/p>\n

When the currents reach transformers in the Transpower substations or the large hydroelectric dams, they have the potential to cause significant damage.<\/p>\n
