You asked: Where are the geothermal fields in Aotearoa and where are the geothermal power plants located?

New Zealand’s high-temperature geothermal fields are mostly concentrated around the Taupo Volcanic Zone (which also has most of the currently operating generation capacity), in the central North Island, with another major field at Ngawha Springs in Northland.

Where are the geothermal plants located?

The largest group of geothermal power plants in the world is located at The Geysers, a geothermal field in California, United States. As of 2004, five countries (El Salvador, Kenya, the Philippines, Iceland, and Costa Rica) generate more than 15% of their electricity from geothermal sources.

How many geothermal power plants are there in New Zealand?

Five entities operate geothermal power stations: Mercury Energy (489 MWe), Contact Energy (420), Top Energy (25 MW), Ngati Tuwharotoa Geothermal Ventures (20.5), Eastland Energy (9.5), and Nova (3.3). Three fields (Mokai, Ngatamariki, and Rotokawa) have operations that are co-owned with local iwi.

What are the 7 geothermal fields in the Philippines?

Philippine geothermal resources are spread among 7 specific regions: Leyte, MakBan, Tiwi, South Negros, BacMan, Mindanao, and the Northern Negros.

How long does geothermal plant last?

Geothermal systems are built to last a very long time. “The indoor components typically last about 25 years (compared with 15 years or less for a furnace or conventional AC unit) and more than 50 years for the ground loop,” The Family Handyman magazine reports.

Can geothermal energy run out?

Geothermal energy isn’t entirely renewable—it will run out when the Earth does. In about 5 billion years.

Can geothermal plants be built anywhere?

Unfortunately, geothermal power plants can’t be built anywhere. Geothermal reservoirs above 100°C are usually necessary for most large geothermal plants, and these reservoirs are only found in specific locations, usually near tectonic plate boundaries or hot spots.

Why geothermal plants can work well in NZ?

Geothermal energy has been described as New Zealand’s most reliable renewable energy source, above wind, solar and even hydroelectricity, due to its lack of dependence on the weather.

Why are geothermal reservoirs common in New Zealand?

Geothermal areas are commonly close to the edges of continental plates. New Zealand’s location on an active plate boundary (between the Indo-Australian and Pacific Plates) has resulted in numerous geothermal systems and a world-class geothermal energy resource.
