Ventus is developing six new wind farms in New Zealand’s upper North Island.
Located close to centers of high demand, Ventus’ state-of-the-art generation will deliver 2,600 GWh per year of low-cost, renewable electricity to power cities and industries into the future.
Our customers are consumer power retailers, manufacturers, data centers and others who need low-carbon, green energy at competitive prices to meet their business and sustainability goals.
We would like to partner with you, too.
New Zealand needs 1,100 GWh of new renewable generation annually for the next 30 years to electrify its energy consumption and meet its emissions targets. Ventus is bringing 2,600 GWh over five years.
Ventus will be the lowest-cost and lowest-carbon electricity producer in New Zealand’s in-deficit power market.
New Zealand is amongst the world’s most suitable locations for wind generation but has one of the lowest penetrations of wind, at less than 10% of capacity.
The upper North Island, which uses 30% of NZ’s electricity and has the highest power prices, is served by only one operational wind farm. Most planned new generation is solar.
Ventus’ wind farm locations and generation profiles will meet demand during daily and seasonal peaks. Wind complements hydropower, which supplies 57% of New Zealand’s electricity.
Wind also has the least embodied carbon of any form of generation besides nuclear and is consistently the most cost-efficient source of power.
By adding competitive, renewable generation when and where it is needed most, Ventus will contribute meaningfully to global environmental goals and help build a brighter future for generations to come.
Ko Aotearoa to tatou whenua tupu. New Zealand is our home. Nothing means more to us than improving it for our children.
Besides accelerating decarbonization and combatting climate change with green energy, Ventus has committed more than $2 million to ecology, community and cultural initiatives in the Waitomo district from our first New Zealand wind farm.
Protecting native avifauna such as Pekapeka tou-roa – the New Zealand long-tailed bat – is a critical responsibility for all of us. That’s why Ventus is funding bat research and supporting initiatives to make New Zealand predator-free.
Ventus acknowledges the interests and aspirations for the future of tangata whenua. We are proud to partner with tangata whenua wherever we work.
