Trustpower generates electricity that powers numerous New Zealand homes and businesses. We have a strong focus on sustainable generation using hydroelectric power stations. We are continually seeking to expand our generation network, as well as make efficiencies, and minimise environmental impacts.

New Zealand

In New Zealand, we operate 38 hydro power stations across 19 hydroelectric power schemes. We have one diesel power station, which is occasionally used for transmission support.

Our focus has been on sustainable forms of generation and how we operate, right from when Trustpower was founded in 1993. Today, this focus supports the New Zealand Government’s long-term Energy Strategy, which commits to a target of 90% of New Zealand’s electricity supply coming from renewable sources by 2025. At present it’s around 70%.

Most simply, sustainability is a responsible approach, locally, nationally, and globally. You’ll find more about our Generation Philosophy and Environmental Policy here.
