Dunsandel upgrades for Synlait


Orion upgraded the capacity at its substation in Dunsandel to power local dairy processor Synlait’s installation of a new electrode boiler.

Synlait is installing New Zealand’s first large-scale electrode boiler in their upcoming $125 million advanced dairy liquids facility at Synlait Dunsandel. Commissioned in early 2019, the move from a coal fired boiler to electricity is part of Synlait’s sustainability strategy and leads the way for industry to contribute to a lower emissions future for New Zealand.

Orion more than doubled the transformer capacity, swapping out 10 MVA transformers to 23 MVA and adding two additional 11kV supply cables – sufficient to service the electrode boiler’s initial capacity of 6 megawatts.

Neil Betteridge, Director Operations, Synlait Milk said, “As a growth company, we need partners who can help us maintain the reliability of our sites. Orion is a key partner of Synlait Dunsandel and we’re proud to work with the team.”

The new boiler is expected to save 13,714 tonnes of CO2e per year, or the equivalent of removing 5,300 cars from the road per annum.
