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.

The original article has been fleshed out and they now say it's because a lot of generation is offline for maintenance ahead of winter, and this cold weather is earlier than expected.

If you wanna poke around with some historical data yourself, I scrape a lot of it for my own curiosity, and have opened up my dashboard

Oh wow heaps of cool stuff there! What happened to hydro in 2021/2022? Capacity doubled overnight, is this just a measuring issue? graph of electricity sources in NZ by type for last 5 years showing hydro jumping in capacity on 1 Jan 2022
