Bream Bay Power Station is sited in the upper North Island of New Zealand. The station is our only one powered by diesel generators. Nationwide, we are committed to using natural resources and sustainable generation. However, Bream Bay provides an important backup, helping us to ensure reliable power supply at all times.

At a Glance


Commissioned 2011

Max Capacity 9 MW

Annual output Depends on need

Bream Bay’s diesel generators stand alongside the New Zealand Refinery Company near Whangarei. Installed in 2011, the five Caterpillar generators have a combined output of 9 MW. Each generator has a 5,000 litre fuel tank and all five are connected to a 30,000 litre bulk storage tank. 

The Station is connected to the grid via Northpower’s distribution network and is used during high loads and in times of reduced power security. 

Environment and recreation

We are highly aware of the need to operate in a sustainable manner and you can read about our generation philosophy here. However, the amount of available water and wind varies from season to season and from year to year. So too does power demand, which also reflects weather patterns. 

For businesses and communities around the country, it is vital for us to provide reliable power supply at all times: and this is why we have Bream Bay.
