Power generator and retailer genesis energy is in advanced talks to help build New Zealand's biggest solar farm.

The developer is under wraps for now, but the project's being proposed for Northern Waikato, and it would be ten times bigger than the solar farm currently planned by Refinery NZ at Marsden Point.

The plan will generate 550 gigawatt-hours of electricity.

Genesis Energy's CEO Marc England joined Kate Hawkesby to discuss how the project would work and why they are investing in solar power.
