Lake Onslow is economically hellish.
The alternative to gas peakers is North Island intra-week storage.

Dry years problem solved, more wind power, North Island pumped hydro – New Zealand 100% renewables without Onslow

Lake Onslow pumped hydro scheme considered for fast-track by government A prominent backer of the Lake Onslow pumped hydro scheme says he's already fielding interest from international investors.

So glad to see Lake Onslow is back on the table. 👍
I hope this time the project is not politically demonized. Countless gas-fired peaker plants is a poor strategy for a small young nation at the far end of the global supply chain.
