The Coleridge Power Station is a hydroelectric facility at Lake Coleridge on the Rakaia River in Canterbury, New Zealand. The power station is owned and operated by TrustPower. Annual generation averages 270 GWh, following redesign of the station's turbines using Computational Fluid Dynamic modelling [1].
Coleridge was the first major power station in which the state was involved, with construction starting in 1911. Following its initial construction, the twin 66 KV transmission lines were the longest (100+ km) and highest voltage in New Zealand.[2]
