(02) — What we deliverEngage one stage or all four
Our services, in detail.
From identifying the right land to commissioning the final installation, one accountable team manages every stage.
Identify. Secure. De-risk.We source, evaluate and secure high-quality land for utility-scale solar.
We manage the full engagement and due diligence process so each project begins with a bankable foundation.
- Identifying land with optimal solar potential and grid proximity
- Engaging and negotiating directly with landowners
- Preparing and securing land term sheets, HOAs and exclusivity agreements
- Assessing planning, zoning, overlays and environmental constraints
- Site screenings: geotechnical, soil, flood and ecological checks
- High-level network capacity and feasibility assessments
- A complete handover package for engineering and design
Outcome
Bankable, development-ready land secured with strong landowner relationships and minimal early-stage risk.
Design. Optimise. De-risk.Robust engineering, from concept design to grid connection.
Our engineering team makes sure every project is feasible, efficient and compliant, with full technical support at every step.
- Preliminary engineering, site layouts and solar yield modelling
- Concept, detailed and IFC-level system design
- DC/AC, MV/HV and SCADA integration design
- Grid connection studies, submissions and regulatory liaison

(04) — Real estate × renewablesSourcing & consents
How we source land
Land is the first engineering decision.
Through our network of landowners, real estate partners (including The WORX) and regional councils, we identify suitable sites and run full feasibility on grid proximity, topography, irradiance and consent pathways before recommending anything.
The regulatory pathwayHandled end to end
Compliant from day one.
We manage the full regulatory pathway and work closely with the people who decide whether a project connects.
- Resource consents
- Grid connection applications
- Building consents where required
- Close work with councils, lines companies and Transpower
