, New Zealand's largest power station. Genesis Energy owns and operates a diverse portfolio of assets that includes hydroelectric, thermal and wind generation. Genesis Energy operates three
hydroelectric generating stations on the (361.8 MW)
Tongariro Power Scheme – Rangipo (120 MW), Tokaanu (240 MW) and Mangaio (1.8 MW). It also operates the (138 MW) Lake Waikaremoana hydro scheme, comprising the Tuai (60 MW), Kaitawa (36 MW) and Piripaua (42 MW) stations. On 1 June 2011, Genesis Energy purchased Tekapo A (27 MW) and B (160 MW) hydroelectric power stations from
Meridian Energy. Genesis Energy operates the
Huntly Power Station, a (953 MW) coal- and gas-fired thermal plant on the
Waikato River. In addition to two gas/coal-fired generating units, Huntly has a 50 MW open-cycle gas turbine unit that runs as base load, and a (403 MW)
combined cycle gas turbine commissioned in June 2007 as a
NZ$500 million project. Huntly also has a third coal unit, which can be taken out of storage within 90 days. The coal units are mainly used as hydro firming when New Zealand is in a dry winter. The company also operates the (7.3 MW) Hau Nui
windfarm in the North Island.
Future generation developments Castle Hill Genesis Energy has resource consents for a wind farm at Castle Hill, 20 km north-east of Masterton in the northern Wairarapa. It is planning up to 286 turbines over a area, with a total installed capacity of up to 860 MW and potentially generating over 2000 GWh per year. In March 2023 Genesis applied to extend the resource consent for the wind farm and vary its conditions. Its proposal involves reducing the size of the windfarm to 300MW. Consent was granted in October 2023, and now expires in 2031.
Slopedown Wind Farm In 2010, Genesis Energy purchased the
Southland Wind Farm aka Slopedown wind from Wind Prospect CWP Ltd. It is 15 km east of
Wyndham. Genesis Energy has not yet applied for resource consents. This appears to be a Contact Energy project now as stated in
Southland Wind Farm. ==Community and sustainability investments==
