Transpower has issued a notice saying there was a risk power generation would not meet demand in the morning.

The national electricity grid operator is warning of possible insufficient power generation to meet households’ demand on Friday.

Transpower has issued a notice saying there was a risk that power generation and reserves would not meet demand between 7.30am-8.30am.

It said if power generators could not provide enough electricity, Transpower would manage demand to avoid a grid emergency.

“The system operator may instruct the grid owner to disconnect feeders without further notice to connected parties,” it said.
