Darfield SOLAR & ENERGY STORAGE PROJECT
THE PROJECT
The Darfield Solar & Energy Storage Project (DAR) is a 117 MW (DC) utility-scale renewable energy development located approximately 1.5 kilometres north of Darfield, Canterbury. The project comprises 117 MW of solar photovoltaic (PV) generation and includes an optional Battery Energy Storage System (BESS) with a capacity of up to 106 MW / 200–400 MWh. Designed for a 40-year operational life, DAR is positioned to make a meaningful contribution to decarbonising New Zealand’s industrial energy use and strengthening grid reliability.
The project will generate approximately 210 GWh of electricity per year, supplying enough energy to power approximately 23,000 homes and reducing annual carbon emissions by an estimated 12,000 tonnes.
Located at off Homebush Road, the 148-hectare site sits directly alongside the Fonterra Kimberley Factory, enabling the project to supply a large industrial load. This proximity allows for an offtake opportunity under a Power Purchase Agreement (PPA), and NZCE is in discussions with Fonterra. The remaining energy will be exported to the national grid via the 66 kV network, creating dual offtake pathways and commercial flexibility.
The grid connection point is the Orion-owned Kimberley Substation, which is located within the Fonterra facility and is fed by Transpower's 66 kV lines. The project will connect via underground cable and make use of existing infrastructure wherever possible to reduce capex and ensure grid compliance.
The land is currently used for sheep grazing, which will continue post-construction. Its flat and obstruction-free layout supports efficient installation and minimises engineering complexity. The site is zoned General Rural under the Selwyn District’s Partially Operative District Plan (PODP). Construction is expected to take approximately 12–18 months, generating approximately 100 construction jobs during the build phase and ~20 operations and maintenance roles thereafter.
Technically, DAR will include approximately 187,824 solar panels, supported by 24 inverters and 24 additional BESS inverters.
With its rare combination of proximity to a major industrial load, strong grid access, and ongoing land use compatibility, the Darfield project represents a strategic opportunity in New Zealand’s clean energy landscape. NZCE looks forward to delivering this landmark project and engaging further with stakeholders as development continues.
Current status
Development milestones are advancing. Resource Consent is expected in Q3 2025, with grid connection agreements and geotechnical investigations also scheduled for completion in the same period. NZCE is targeting Ready-to-Build (RTB) status by Q4 2025, with financial close and construction commencing in 2026.
Looking ahead, NZ Clean Energy (NZCE) plans to launch a formal Engineering, Procurement and Construction tender process, and finalise equipment suppliers. With the assistance of our appointed Technical Advisor, we will be running through the EPC tender for the project. In parallel, NZCE will conclude the PPA (Power Purchase Agreement) negotiations and financing arrangements, thus allowing us to achieve Notice to Proceed (NTP) in 2026. Please keep updated with our progress either on this website page or our LinkedIn page.
Why has this site been selected
-
The main factor for identifying and choosing the site is the proximity to the grid. The site is adjacent to the Kimberley substation which is the point of connection. This allows for a firm and reliable connection.
-
Grazing land has been identified and as such there will be a fractional loss of agricultural land as grazing will continue on the land post construction.
Limited impact on native vegetation / biodiversity. All existing native vegetation on site is intended to be retained.
-
The local community has been engaged with a public drop in session and the distribution of project information. This engagement has ensured we develop the most suitable project possible in conjunction with the key stakeholders. In addition Fonterra - whose Darfield factory sits next door - are very supportive of the project.
-
Darfield Solar Farm has high levels of solar irradiation allowing for a high performing renewable energy system. Demand for electricity in the surrounding area is increasing year on year.
Benefits of the Project
-
This project will produce energy for use in the local area, i.e. generated close to where it is used. Increased energy security for the local area and wider network.
-
During construction we anticipate over 100 jobs being created for each project, ranging from electrical and solar PV work to security and groundworks.
-
We are actively encouraging local business to get in touch with us to register their interest in the project so we can get as many local companies involved as possible.
-
A number of jobs will be created such as panel cleaning & maintenance, general testing and inspecting of electrics and general site maintenance and upkeep.
-
Will be available to local schools and community groups wishing to visit to understand more about the project and what is involved.
-
Will be in place to explain to the local are and any passers-by what the project details are.
