Winstone, which sourced power directly from the wholesale market, blamed high power prices for the mills’ closure after the spot rate spiked to more than $800 a megawatt hour (MWh) in early August in response to low hydro lake levels and a gas shortage.

“New Zealand’s economic growth and prosperity relies on Kiwi households and businesses having access to affordable and secure electricity at internationally competitive prices,” he said.

“Now we need the right regulatory and market conditions to encourage the development of gas-fired peaking plants and the fuel we so badly need to keep the lights on,” Carnegie said.
