Power station

MainPower’s Cleardale power station, was built in 2010. It takes up to 450 l (99 imp gal; 120 US gal)/second[6] through a fibreglass penstock,[7] 2.3 km (1.4 mi) up from,[6] and 300 m (980 ft) above,[8] the station, to drive a 1 mW (1.3×10−6 hp) pelton wheel.[6] Power is generated at 400 volts and transformed to feed into Electricity Ashburton's 11 kV network.[8] Some water from the tailrace is used to irrigate 208 ha (510 acres),[9] with the remainder returned to the river.[6] The power station and penstock have been landscaped[10] and are now barely visible.[11]
