Ohaaki is a 122 MW geothermal power plant located in New Zealand, operated by Contact Energy. Commissioned in 1984, it contributes to the country's renewable energy portfolio. This facility ranks as the 3rd largest geothermal plant in New Zealand. With a capacity of 122 MW, it represents 18.32% of New Zealand's total geothermal capacity of 666 MW. The country has 7 geothermal plants with a combined capacity of 666 MW, while the largest geothermal facility, Nga Awa Purua, has a capacity of 138 MW, making Ohaaki approximately 88% the size of that plant. Geothermal energy is a significant resource for New Zealand, providing around 17% of the country's total electricity generation. The unique geothermal features in the Taupo Volcanic Zone facilitate this energy source. The plant is located in the Waikato region, approximately 40 km from Rotorua.

Geothermal power generation harnesses the Earth's internal heat to produce electricity. This renewable energy source exploits the thermal energy stored beneath the Earth's crust, which can be accessed through geothermal power plants. These plants typically utilize steam or hot water from geothermal reservoirs to drive turbines that generate electricity. The process begins by drilling wells into geothermal reservoirs, often located in tectonically active regions, where the temperature gradient is favorable for energy extraction. The steam or hot water extracted is then channeled to turbines, converting thermal energy into mechanical energy, which is subsequently transformed into electrical energy by generators.
