Aratiatia Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is the first hydroelectric power station on the Waikato River, and is located 13 kilometres (8.1 mi) downstream of Lake Taupō. Aratiatia is owned and operated by Mercury Energy.[1][2]
Aratiatia is a largely run-of-the-river station, as it generates electricity from water from the Lake Taupō control gates and to the Ōhakuri Power Station. It does, however, have a 55-hectare (140-acre) lake behind the station for temporary storage.
The New Zealand Ministry for Culture and Heritage gives a translation of "pegged ladder" for Aratiatia.[3]
