Coronet Peak flips the switch on $2 million "snow factory"

Weeks before the lifts usually start spinning, Coronet Peak has flipped the switch on a game-changing $2 million "snow factory" to lay down its first coat of the season in autumn.

Housed in shipping containers, the high-tech, fridge-like machine freezes water and converts it into snow, operating in temperatures of up to 20°C. The innovation is paving the way for Coronet Peak’s learners and ski play areas to open on 29 May, roughly two weeks ahead of schedule.

Ski area manager Nigel Kerr highlighted that the electric unit is the first of its kind in the South Island. Unlike traditional snowguns that require sub-zero conditions, this system can run around the clock.

"It's turning about 10,000 litres of water a day into about 240 cubic metres of snow, made up of small frozen particles," Kerr said. "It's so cold that it actually doesn't stick together."

Targeting the "Achilles' Heel"

The system has already churned out at least 800 cubic metres of what Kerr describes as "less snowball, more sprinkle-style snow." It is being deployed directly to build a solid base on the mountain's lower slopes—an area traditionally plagued by thin coverage.

"This is our Achilles' heel, the bottom of the mountain, so this is where we need to make the snow." — Nigel Kerr, Ski Area Manager

The technology boasts several environmental and operational advantages:

• Zero Chemicals: The process requires absolutely no chemical additives.

• Wind Resistant: Unlike traditional misting snowguns, flakes are not lost to the wind.

• Zero Waste: Snow is created in situ (on-site). "We're not pushing it with the snowcats," Kerr noted. "We're actually making the piles in situ, so there's no wastage."

A Summer of Heavy Lifting

Getting the factory operational required an intense summer engineering project. Head of slopes Eddie Boxer explained that crews spent months laying pipes, pouring concrete, and installing power and water infrastructure.

"Our pre-Christmas and into the New Year project was getting all the infrastructure in place," Boxer said. "There's a lot of steel and about 42 cubic metres of concrete, plus four-metre piles underneath it to support it all."

Once the groundwork was laid, technicians from the Italian company TechnoAlpin arrived to land the structure. The physical assembly was remarkably swift. "Within a day, we had everything stacked up with the crane and then it took about another week-and-a-half to fit it all," Boxer added.

For the crews on the ground, seeing the machine fire up for the first time was surreal. Snowmaking team lead George Morrissey recalled the launch: "It was a pretty warm night. It felt pretty strange actually seeing snow in conditions that we shouldn't have... just being able to flick a switch and have it come out was pretty impressive."

Early Snow in the Community

While the bulk of the early output is earmarked for the mountain's expanded learner slope and snow play area, some of the autumn snow has already made its way off the mountain.

Crews recently took a utility vehicle loaded with the fresh powder to the Arrowtown Autumn Festival. "It was a crowd favourite, I reckon. The kids went crazy for the snow," Boxer said. Town locals can also expect a taste of the mountain soon, as some of the first batches will be trucked into central Queenstown for an urban ski competition on 29 May.

Weather Proofing the Season

While Queenstown's tourism sector is booming, unpredictable weather remains a constant challenge for operators. Early season snowfall was well below average last year, and the ongoing climate patterns threaten to bring highly volatile conditions.

Kerr emphasizes that the $2 million investment is all about providing certainty to early-season visitors and seasonal staff who rely on guaranteed opening dates.

"Not every year goes to plan. It's nice to have a backstop," Kerr said. "This is our backstop."
