Arapuni Hydro Power Station

Arapuni Power Station is a hydroelectric power station on the Waikato River. It is also the currently generating, the first government-built, and the largest single hydroelectric power station on the Waikato River.

The station, complete with three turbines and provisions for a fourth, was commissioned in mid-1929. The station, with the addition of a fourth turbine, was recommissioned in May 1932.

n 1934, increasing demand for electricity resulted in Arapuni being extended. The powerhouse was doubled in size, and provisions for four more turbines were made. Turbines 5 and 6 were commissioned four years later in 1938. The last two turbines were commissioned in 1946.

In 2001, work was completed on four of Arapuni's turbines to increase capacity from 24.7 MW to 26.7 MW each and to improve their peak efficienct.
