Generation

Mighty River Power’s electricity generation in New Zealand comprises three complementary fuel sources – hydro, geothermal and gas-fired.  More than 90% of our generation comes from renewable resources.


Our Generation Assets
HYDRO
9 Stations on the
Waikato River

Flexible and rain-fed, hydro output can be increased or decreased quickly and efficiently.
GEOTHERMAL
5 Stations through the
central North Island

Steady base-load geothermal runs at full capacity about 95% of the time.
GAS-FIRED
1 Station,
Southdown, Auckland

Flexible gas-fired generation can respond to wholesale market opportunities and covers dry-year risk.
