Masterton Solar and Energy Farm
PROJECT INFORMATION
The Masterton Solar & Energy Storage Project is a 100 MW solar farm in Waingawa, Wairarapa, with optional battery storage of up to 91 MW / 200–400 MWh. Designed for a 40-year lifespan, it will generate 166 GWh annually — enough to power 20,000 homes — and reduce carbon emissions by 12,000 tonnes.
With strong grid access, proximity to local demand, and compatibility with ongoing agricultural use, it stands as a flagship clean energy initiative for the region.
Current Status
As of Q2 2025, the Masterton project has achieved Ready-to-Build (RTB) status. Key development milestones include securing the land, receiving Resource Consent in November 2024 (Carterton District Council Notified Resource Consent), signing the Transpower Works Agreement in Q1 2025, and completing both geotechnical investigations and technical advisory appointments.
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 the coming months. 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 ~50m from the substation at Masterton (adjacent to) which is the point of connection. This allows for a firm and reliable connection to the National Grid.
-
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.
-
Initial research suggests support for renewable energy projects. This allows for us to ensure we develop the most suitable project possible in conjunction with the key stakeholders.
-
Masterton 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.
