We have 9 hydro generation stations on the Waikato River. These stations are flexible and rain-fed. Hydro output can be increased or decreased quickly and efficiently.
We have 5 geothermal generation stations through the central North Island. Steady base-load geothermal runs at full capacity about 95% of the time.
Lake Taupo has water flowing into it from many sources, but only one river flows out – the Mighty Waikato, New Zealand’s longest river.
Water is vital to our business as it is essential to our 100% renewable generation sources. We carefully manage the Waikato river, home to our hydro dams.
