Aniwhenua is named after the falls which are adjacent to the power house. The Aniwhenua scheme consists of a 200 meter long, 10 meter high dam structure with two radial control gates which can discharge 1,270 cubic meters of water per second. Three additional flap gates are designed to handle higher flood conditions. A 2.2 kilometer canal with a fall rate of 1 in 2,500 diverts water from the lake to a head pond above the powerhouse. Water flows from the head of the pond through steeply dropping penstocks at a rate of 75 cubic meters a second to the powerhouse. There, it drives two 12.5 MW generators before being discharged back to the river just below the Aniwhenua Falls. |  | EL Database,Electricity Commission,EMS (Reconciliation Manager [NAME]) |  | GEN.Hydro.Aniwhenua

Due to its close proximity to [NAME]'s urban centre, Arapuni provides a voltage support role for power transmissions to the area. Recent upgrades to the station have enhanced its capability in this area. This station is occasionally used for frequency keeping. The Arapuni power station was the first government-built hydroelectric station on the Waikato River. During the initial surveying in 1916, an old watercourse was found just upstream of one of the narrowest parts of the gorge. In 1920, the surveying was halted due to lack of government funds to progress the project.  Construction finally began in 1924, but repeated heavy rain and the resulting floods dogged the early works. Just after the project was commissioned in mid-1929, the station was closed for two years while a water seepage problem was investigated and the headrace lined. The station began operating again in May 1932 with four generators installed. Four more machines have since been added. In 2001, work was completed on four of Arapuni's turbines to increase capacity from 24.7MW to 26.7MW each and to improve their peak efficiency to 94 percent. |  | EL Database,Electricity Commission,EMS (Reconciliation Manager [NAME]), www.mightyriverpower.co.nz | 7 | GEN.Hydro.Waikato.Arapuni

The Government completed a study of the suitability of the area for hydro electricity generation in 1906 and commenced work in 1911. In 1914 the power station was commissioned with three turbines and was then progressively expanded over the next decade. Much of the station still dates from this period. In 1930 the Acheron River was diverted into Lake Coleridge, increasing the catchment area to more than 800 square kilometres and in 1977 a diversion of the Wilberforce River further increased the amount of water, boosting average annual output to 205 GWh. The Coleridge power station is fed from Lake Coleridge via 2 kilometres of tunnels and pipes, and after passing through the powerhouse the water empties into the Rakaia River approximately 140 meters below the level of the Lake. Lake Coleridge can store 2 to 3 months inflows. TrustPower purchased Coleridge from ECNZ in October 1998 for $91 million and over the next two years upgraded the station at a cost of about $6 million. The investment increased capacity from 36 MW to 45 MW and target annual output from 205 GWh to 300 GWh. Resource consents to re-permit the existing scheme were granted in 1996 for a 35-year term to 2031. |  | www.trustpower.co.nz, EL Database,Electricity Commission,EMS (Reconciliation Manager [NAME]) |  | GEN.Hydro.Coleridge

Fed by the Hinemaiaia River, the scheme today consists of 2,400kW HA, 1,350kW HB and 2,850kW HC stations giving a total annual output of 29.3GWh. The 33 hectare lake of the HA Station has an average depth of only 1.2m and contains 16.6 hours of storage at mean river flow. The river carries considerable pumice debris and the original lake was fully silted in it's first 25 years of existence.  Levees have been built to form future silt ponds for the time when dredging of the lake area above the weir will become necessary to maintain storage. The HA lake is a wildlife sanctuary and has become the habitat of a wide variety of wild fowl. The lake in the past has been stocked with salvelinus fontinalis brook trout by the Wildlife Conservancy. The HA dam is comprised of an arch dam 12m deep in a narrow ignimbright gorge with an adjacent 90m long weir perched on the surface of the ignimbright rock with the intake structure situated on the left bank at the end of the weir.  A remote controlled and hydraulically operated bypass gate has been placed in the dam which is capable of passing 5 cumecs when required.  The intake chamber contains hydraulically operated bypass gates, intake screens and screen scraper mechanism. The screen scrapers cope with pumice debris and lake weed and the scraper operation is initiated by both pressure differential across the screen and time switch control.  Two 243 metre long penstocks, one 1.67m in diameter and one 1.8m in diameter, lead from the intake chamber to the power station.

The scheme was designed to meet the generating needs of some 235 consumers. The Kourarau Power Scheme does not feed directly into the national grid. The electricity is distributed throughout the Wairarapa area. Each station is fed by a small artificial reservoir formed by the damming of Kourarau Stream. Between each reservoir and the associated power station are sections of pipeline and penstocks that take water from the reservoir to a power station. Water from the Lower Power Station is discharged back into the natural channel of the Kourarau Stream. The Upper Dam and Reservoir were formed in 1925 by the damming of Kourarau Stream with an earth dam. The reservoir covers approximately 15 hectares. Water from the upper reservoir is taken through the Upper Power Station at a maximum rate of 290 litres per second. The upper reservoir has a normal operating range of 650 mm between minimum level and the spillway crest. During floods water that cannot be taken into the power station flows over the spillway and into the natural channel of Kourarau Stream. The Upper Power Station is a 200 KW (actual generator rating 250KW) station that uses a maximum flow of 290 litres per second to generate electricity. Water enters the Upper Power Station from the Upper Reservoir via a 785 metre long pipeline and single penstock system. A surge chamber is situated between the penstock and the pipeline to relieve pressure from the system that builds up due to fluctuating flows and generation patterns. The Lower Reservoir is 1.4 hectares in area and located downstream of the confluence of the Kourarau Stream and Sailormans Creek. The reservoir is formed by an earth dam, approximately 4 metres in height. Water enters the lake from the Upper Power Station tailrace and from the Kourarau Stream, including the flow from Sailormans Creek. The upper level of the lake is controlled by a fixed weir concrete-lined spillway. During floods, any water that cannot pass through the Lower Power Station, via the intake, flows over the spillway down the natural channel of Kourarau Stream. From the Lower Reservoir, water passes through a single 1182-metre pipeline to a surge tower. The pipeline then splits into two penstocks that carry water a further 2136 metres to the Lower Power Station. Water enters the two penstocks at a maximum rate of 900 litres per second. The Lower Power Station is a 900 KW station (actual generator rating 700 KW) situated adjacent to Kourarau Stream. Water then passes through a short tail-race before being discharged back into Kourarau Stream. |  | Electricity Commission,EMS (Reconciliation Manager [NAME]) |  | GEN.Hydro.Kourarau

The turbines, generators and other equipment are contained in the powerhouse located in an underground cavern. The cavern was cut from solid rock and is 111 metres long, 18 metres wide and 39 metres high. Vehicles can drive down to the powerhouse through an access tunnel which is more than two kilometres long. It descends at a 1-in-10 gradient, and is wide enough to allow vehicles to pass. The powerhouse can also be reached by an elevator which descends 220 metres (equivalent to a 70-storey building) in two-and-a-half minutes. Uses 178 metre height difference between Lake Manapouri and the sea at Deep Cove. Once water has passed through turbines it leaves the station through two 10 kilometre-long tunnels to Deep Cove. The station was originally built with only one tailrace tunnel, but a second tunnel was commissioned in 2002. Reconditioning of the plant and the new tail race have resulted in an increase in maximum output, although actual output is constrained by resource management requirements. |  | www.meridianenergy.co.nz,EL Database,Electricity Commission,EMS (Reconciliation Manager List),ACS data |  | GEN.Hydro.Manapouri

The water passes through two power stations Rangipo (120MW) and Tokaanu (240MW) before being released into Lake Taupo. The scheme taps a catchment area of more than 2600 sq km and uses a series of lakes, canals and tunnels to bring water to the two stations which typically generate 1400 GWh p.a.—about 4% of the country's total electricity generation.  The western diversion takes water from six rivers and streams from the Whakapapa River to the Whanganui River, into Lake Rotoaira via Lake Otamangakau. The Tokaanu power station is connected to Lake Rotoaira via a six kilometre tunnel through Mount Tihia. It also draws water from the Tongariro River via the Poutu tunnel and canal. On the eastern side of Mount Ruapehu, water is diverted from the Kaimanawa Ranges and headwaters of the Wahianoa River through a 20 km tunnel into the Rangipo dam.

Construction contracts were let in mid 1977, and the station was commissioned in 1981, but a failure in the feed canal later that year required major rebuilding. The station was recommissioned in 1983. The reservoir for this station is [NAME] and the canal links the reservoir to the station. [NAME] was formed in 1925 by the construction of a 26m high concrete arch dam across the lower Mangapapa River to operate the now decommissioned McLarens Falls Power Station. Water from the lake passes through a gated inlet structure into a 2.5 kilometre long canal. The construction of the canal involved moving 2, 400, 000 cubic metres of soil at depths up to 46 m below original ground level, making it one of the larger canals in New Zealand. The depth of the water in this canal is 6m and the width at normal operating level is 30m. Flow velocities are up to 0.9m per second depending on machine settings and water levels. Transition from the canal to penstock is a forebay which again has screens, a cleaner and control gates. Downstream of the forebay is a 1.6km low pressure conduit leading to twin high pressure penstock pipes down the escarpment and under State Highway 29 into the power house. |  | Electricity Commission,EMS (Reconciliation Manager [NAME]) |  | GEN.Hydro.Kaimai.1

Currently, about 5,000 tonnes per hour of fluid is taken from the reservoir. This is separated into roughly 1,500 tonnes per hour of steam and 3,500 tonnes per hour of water at a temperature of about 130°C. Dry steam is also taken from shallow production wells (up to 500 m depth) and piped directly to the turbines. The steam is directed towards the turbines through the network of pipes around the Wairakei steam field.  Once steam has passed through the turbines it is condensed within 'direct contact' condensers. This cooling system uses water pumped from the adjacent Waikato River. After use, the cooling water and steam condensate is discharged back into the river. Gases found in the steam supply are pumped from the condenser and released to the air via gas stacks situated on the power station roof. The hot geothermal water is discharged into a system of drains (that lead to the Waikato River), or it is injected back into the ground. The Binary Plant uses heat energy in waste hot water to drive two 8 MW generators. However the binary plant needs about 2MW of power just to run its own pumps and fans so the overall generation is 14MW |  | EL Database,PB 'Thermal & Geothermal Generation Capabilities',Electricity Commission,EMS (Reconciliation Manager List),www.nzgeothermal.org.nz |  | GEN.Geothermal.Wairakei

The scheme is run of the river. Water is collected from small intakes on the north and south branches of Wye Creek which fee 1350m of pipeline varying from 450mm to 600mm in diameter, which in turn supply a small power house downstream of the State Highway 6 road bridge. The scheme was upgraded in 1991 with the addition of a generator, turbine, renewal of penstocks, and foundations and exterior cladding of the powerhouse. The Wye Creek scheme has a peak generation output of 1.35 megawatts and an average energy production 10 Gigawatt hours. |  | Electricity Commission,EMS (Reconciliation Manager [NAME]) |  | GEN.Hydro.WyeCreek
