Meridian Energy is building a $227 million solar farm at Ruakākā. It covers 163 hectares across three sites at Marsden Point, with 250,000 panels producing up to 230 gigawatt hours of electricity per year. That is enough to power roughly half the homes in Northland. First generation is expected in late 2026, full commissioning in early 2027.
What is actually being built
The numbers are large enough to be meaningless without context. 250,000 solar panels. 163 hectares. 170 rugby fields. What that looks like on the ground is three blocks of farmland behind the Marsden Point industrial zone, covered in rows of tilted panels facing the Northland sun. The sites sit between Marsden Point Road and the harbour, well away from the beach and the residential streets.
The project is Meridian's first grid-scale solar farm in New Zealand. It has a peak output of 130 megawatts and will produce up to 230 GWh of electricity annually. For comparison, that is more than three times the output of the largest solar farm operating in New Zealand when this project was consented.
Construction started in August 2025. Ethical Power, a renewable energy contractor with a track record in the UK and a growing New Zealand operation, holds the construction and maintenance contracts. First power is expected late 2026, with full generation from early 2027.
The energy park
The solar farm is stage two of what Meridian calls the Ruakākā Energy Park. Stage one, a 100 megawatt battery energy storage system, is already operational on the same site. The battery stores electricity when supply exceeds demand and releases it during peaks, which smooths out the variability that comes with solar generation. Together, the two systems give the Northland grid both a significant new source of renewable power and a buffer to manage it.
The battery has a storage capacity of 200 MWh. At maximum output it could sustain power to around 60,000 average households for two hours. Both systems connect directly to Transpower's Bream Bay substation.
Why this matters for Northland
Northland has historically been vulnerable to power supply issues. The region sits at the end of the national grid, dependent on electricity generated hundreds of kilometres to the south and transmitted north through a narrow corridor. When transmission lines go down, Northland feels it first.
The solar farm changes that equation. Generating power locally, at scale, reduces Northland's dependence on the long-distance grid. Meridian's chief executive Neal Barclay put it directly: the project adds energy resilience to a region that has learned, in recent years, how much that matters.
The broader context is a wave of solar development across Northland. Lodestone Energy's Kohirā solar farm near Kaitāia is already feeding the national grid. The Far North Solar Farm at Pukenui is operational. Meridian's Ruakākā project is the largest of the group and positions Bream Bay as a genuine energy hub.
What it means if you are visiting
Nothing, practically. The solar farm is on farmland behind the industrial zone, not on the beach or the dunes. You will not see it from the surf club, the estuary or any of the walking tracks. The panels face the sun, the cows grazed elsewhere, and the beach carries on as it has since Cook named the bay for its fish.
If anything, the project is a good story: a community that lost its refinery and gained a solar farm, a battery and a port expansion in the space of a few years. Marsden Point is remaking itself, and the beach is better for it.
