New Zealand Launches Groundbreaking Grid Battery
On November 11, 2023, Genesis Energy commissioned a pioneering grid-scale battery system at the Huntly thermal power station in New Zealand. This cutting-edge installation boasts a power output of 100 megawatts and an energy storage capacity of 200 megawatt-hours. The project features seventy containers equipped with Intensium Shift+ lithium-ion batteries, manufactured by the French firm Saft. Designed to support the grid during peak demand, the battery can supply electricity to 60,000 homes for two hours.
The initiative involved an investment of NZD 130 million (approximately USD 73 million). To optimize costs, Genesis Energy utilized the existing Transpower substation and high-voltage transmission lines. A notable part of the setup included delivering a 172-ton transformer from Auckland port to the Huntly site.
Expansion Plans for Enhanced Capacity
Looking ahead, Genesis Energy revealed intentions to double the battery’s capacity to 400 megawatt-hours with a second development phase. This expansion is estimated to require NZD 106 million in funding. Construction is slated to begin in late 2026, with operational launch expected by 2028. Upon completion, the enlarged battery system will significantly strengthen the region’s energy infrastructure.
"Bringing this advanced grid battery online marks a major milestone for New Zealand’s renewable energy and power storage capabilities,"
Genesis Energy
This innovative project not only reduces reliance on traditional generation but also ensures stable electricity supply during periods of high demand. The planned upgrade reflects growing energy needs and Genesis Energy’s commitment to leading sustainable energy solutions in New Zealand.
