Pātea Dam

The Pātea Dam is a high compacted earth fill–type hydroelectric dam in Taranaki, New Zealand, constructed between 1980 and 1984.

The dam is 82 metres (269 ft) high, and is the fourth highest in New Zealand. It was the first dam constructed using tertiary sandstone and siltstone as fill materials. The dam impounds Lake Rotorangi, which is the longest man-made lake in New Zealand (46 kilometres (29 mi)).^[1]

The Pātea Hydro Electric Scheme was commissioned in May 1984 and was built for the South Taranaki District Council. After construction difficulties, wetter than normal weather had caused a six-month delay. Since 1999 it is owned and operated by TrustPower (now Manawa Energy). With three 11,000 kilowatts (15,000 hp) vertical Francis turbine generator sets and a 700 kilowatts (940 hp) auxiliary generator, the scheme has a total capacity of 33,700 kilowatts (45,200 hp) (33 MW) and an average annual output of 118 gigawatt-hours (420 TJ).
