Our Business

Mighty River Power is one of New Zealand’s largest electricity companies – with a core business based on low fuel-cost electricity generation complemented by sales to homes and businesses. Because we make electricity and sell it to customers, we can better manage earnings variability.


Flexibility is the key to Mighty River Power’s management of its electricity portfolio.  The fact that Mighty River Power participates in the wholesale spot market as both a buyer and a seller, combined with the diversified nature of its production base, including hydro, geothermal and gas-fired generation, enables us to maximise the value of our business and to usually mitigate the risks posed by both hydrological conditions and electricity prices volatility.
