The electricity market responded when hydro lakes were low and gas was scarce. (Image: NZME) Just last winter, New Zealand’s electricity market faced an extraordinary test. A perfect storm combined high demand, low wind generation and a fuel shortage caused by low hydro storage and limited gas supply. Wholesale electricity prices spiked.
Instead, they buy power from an electricity retailer. Retailers buy at the spot price or through contracts with generators and offer electricity to consumers using their pricing plans. In this way, retailers absorb risk from New Zealand’s volatile electricity market, in a similar way to companies providing house or car insurance.
In New Zealand, the electricity ‘shipping’ costs are high because we have high electricity demand in the upper North Island, far away from the South Island, where most of our electricity is generated. What’s causing retail price increases? Most New Zealanders'' electricity bills will have increased on 1 April 2025.
Hydro, gas, coal, geothermal, wind and sun are used to generate electricity in New Zealand (Figure 2). Hydro generation is the largest proportion of these fuels and also has the largest amount of storage as water can be stored in the lakes and released when it’s needed.
