Spanning 201ha across three sites, it will feature approximately 250,000 solar panels over an area the equivalent of about 170 rugby fields.
It’s the second stage of Meridian’s Ruakākā Energy Park, following the completion earlier this year of the company’s 100MW Battery Energy Storage System (BESS).
The BESS facility is designed to absorb excess electricity supply during low-demand periods, release it during periods of high demand, and help smooth out peaks in demand.
It also provides backup during outages and helps stabilise the national grid.
Meridian chief executive Neal Barclay said, “This project is special, not just because it’s our first solar farm in New Zealand, but because it will add so much to the Northland region in terms of energy resilience.”
The project has not been without hurdles. Consent was granted by the Northland Regional Council (NRC) last September, but was challenged by an appeal about environmental concerns.
It was resolved with Meridian agreeing to further enhance the protection of natural wetlands and dunes, and restoration of wetland areas, specifically by the creation of a new 5ha wetland, restoration of 4ha of existing wetland, and 22ha of native planting across the site.
Barclay said the resolution was a positive outcome for the environment and the community.
“We’re committed to increasing the amount of renewable electricity we generate and store so that we can help meet New Zealand’s growing demand for clean energy.”
Meridian general manager of development Guy Waipara said the solar farm was a perfect complement for the company’s many hydro stations and wind farms.
“As more new renewable generation like wind and solar power is built, it’ll lighten the demand on the country’s hydro lakes to produce power year-round and reduce reliance on expensive thermal fuels like coal and gas.”
The project has a strong sustainability focus, he said. More than 79,000 tonnes of construction carbon emissions would be completely offset by the wetland and planting activities. Local employment would be prioritised.
“We know how important it is to be a good neighbour and to do our part for the environment. And once it’s done, we’re planning to show how farming and electricity can co-exist by having sheep grazing between the panels.”
Meridian has awarded the engineering procurement and construction contract to UK-based Ethical Power, which specialises in solar and battery energy storage systems.
Ethical Power New Zealand managing director Matt Rowe said, “Although this is Meridian’s first solar site, Ethical Power is drawing on 15 years of experience in delivering solar PV solutions to ensure the highest quality outcome.
“What makes this project truly special is our shared values around sustainability, environmental care, and community, which will help us build an exceptional project with a positive impact all around.”
Having invested more than $1 billion in the past five years, Meridian is investing a further $2b over the next three years. These projects include the 90MW Mt Munro Wind Farm near Eketāhuna, a 50-50 joint venture with Nova Energy for the 400MW Te Rahui Solar Farm at Rangitāiki, a 100MW BESS in Manawatū, and the Te Rere Hau Wind Farm repowering project, also in Manawatū.
