Uniplas: Large Wellington-based plastics Manufacturer

‍

In late 2024, ZEN Energy partnered with Uniplas, a long-established, major Wellington-based plastics manufacturer and exporter, to support them in improving their energy consumption and costs and reducing their reliance on the grid.

ZEN installed 1,622 solar panels onto the roof of the Uniplas manufacturing premises, currently making it the largest rooftop solar installation in the Wellington region.

This ‘sea of solar’ solution will generate 880KwAC of energy, producing nearly all of Uniplas’ total daily energy needs and equating to be enough to power up between 125-145 NZ homes annually! 

Not only that, but Uniplas are expected to see an 80% reduction of carbon emissions (2,500 tonnes of CO2) saved over the building’s lifetime, the equivalent of 186K trees being planted contributing significantly towards Uniplas’ corporate social responsibility objectives. 

By adopting solar as a core source of energy into its operations, Uniplas is setting itself up as a highly competitive, innovative and future-proofed kiwi business, aligning itself with New Zealand Inc’s sustainability goals on the global stage, and thus ensuring it sits favourably in a market increasingly valuing green initiatives and the reduction of greenhouse gas emissions.

Plus, at a time of increasing local deindustrialisation due to rising energy costs, Uniplas has now achieved a level of energy self-sufficiency, resilience, and affordability that most businesses haven’t even imagined is possible yet.

With energy costs on the rise, we saw an opportunity to make a smart investment, not just for the future of our business but for the planet too. Our new solar system with ZEN is both a hedge against one of our biggest overheads and a reflection of our strong commitment to sustainability. Designed with performance and efficiency, it’s already set to deliver a strong return on investment within a few short years and significantly reduce our carbon emissions. It’s a win for our operations and the environment.
