WAYS WE GENERATE
HYDRO
We have 9 hydro stations on the Waikato River. These harness the power of water to generate on average 10% of New Zealand’s annual electricity supply.
ABOUT HYDRO
WIND
Our wind farms generate electricity from fresh air. Plus, we recently built New Zealand’s largest wind farm.
ABOUT WIND
GEOTHERMAL
We operate five geothermal plants located in the central North Island that power base-load – this means they make power 24/7 ensuring a constant supply of power night and day.
