Leaders in electrical energy and technology.

We take great pride in ensuring we build and maintain a network which will provide the safe and reliable delivery of electricity to our business and domestic customers.

Powering the West Coast

Westpower's shares are held by the West Coast Electric Power Trust on behalf of local electors, ensuring that our decisions remain closely aligned with the interests of the community. Our core purpose is to provide a secure and reliable electricity supply across the region. We accomplish this by maintaining responsive customer service, investing in infrastructure, and continuously enhancing operational efficiency. By fostering local partnerships and supporting community initiatives, we aim to drive sustainable growth and long-term benefits for the West Coast.

Our Future

The global consumption of energy is growing at an ever-increasing rate. As the Government aims to meet its climate target of net zero emissions by 2050, the demand for electrification in the coming decades is evident.

Significant long-term investment in renewable electricity generation across New Zealand is required to help achieve this goal.

This will provide significant opportunities for our consumers and we are committed to partnering them in their future projects. These opportunities make us excited about our future and achieving our vision to become leaders in electrical energy and technology.
