We deliver large-format PV farms as a full EPC contractor — civil earthworks, DC cabling, MV collection systems, inverter stations, substations and grid connection lines, all under a single accountable delivery team.
Utility-scale solar is the fastest-growing generation technology in Australia and New Zealand. We build it right — safely, on program, and connected.
Elecnor Australia delivers utility-scale solar PV farms as a full EPC contractor — covering all balance-of-plant civil and electrical works, from site establishment and earthworks through tracker and panel installation, DC cabling, MV collection ring, inverter and switching stations, and grid connection substations and overhead lines.
Our solar projects are typically 100 MW to 500+ MW in scale, on sites ranging from flat pastoral land to gently undulating terrain. We work with fixed-tilt and single-axis tracker systems, integrating with landholders, transmission planners, and environmental consultants from early design through to energisation and handback.
Solar farms don't exist in isolation — they need substations, grid connection lines, and increasingly BESS co-location to operate reliably and comply with generator performance standards. Our breadth across all three disciplines means developers get a single accountable delivery partner for the whole connection asset package.
Backed by Elecnor Group's global renewables track record — more than 8,000 MW of renewable energy delivered worldwide — our Australian and New Zealand teams bring that engineering depth to every project, combined with the local supply chains, workforce and community relationships that regional sites demand.
From the first stake in the ground to final energisation — our scope covers every discipline a solar farm needs to generate.
Full civil earthworks, access roads, drainage, erosion controls and tracker or fixed-tilt pile installation across large farm footprints.
Panel and tracker installation, DC string cabling, combiner boxes, MV collection ring, inverter stations and SCADA integration.
Step-up substation, protection and control systems, and the overhead or underground connection line to the network — delivered as one integrated package.
One EPC contract, five integrated phases — aligned to the milestones that matter to developers, lenders and network operators.
Layout optimisation, pile design, civil & structural engineering, single-line diagrams, protection settings, grid connection studies.
Global sourcing of panels, trackers, inverters, transformers and switchgear — with factory inspection, FATs and logistics planning.
Site establishment, earthworks, pile driving, cable trenching, roads, drainage and inverter station pads — with full QA audit trail.
Panel & tracker erection, DC string cabling, MV collection ring, inverter station, substation plant and secondary systems.
Pre-commissioning, FAC testing, GPS compliance verification, network operator sign-off, energisation and defect close-out.
Selected by Harmony Energy and First Renewables as lead EPC contractor, Elecnor is delivering the full design, supply and construction of the 202 MWp Tauhei Solar Farm near Te Aroha in the Waikato region — a project that will become New Zealand's largest solar farm on commissioning in late 2026.
"Elecnor will be responsible for the design, supply and the actual construction of the farm, including a substation and an evacuation line — connecting Tauhei to Transpower's 110 kV grid via the Waihou substation." — Elecnor Group announcement, January 2025

What developers and landowners tell us sets Elecnor apart when it comes to utility-scale PV delivery.
ISO 45001-certified HSE management embedded at crew level — across panel erection, electrical works and ground crews operating simultaneously at scale.
Integrated civil and electrical programs — proven across 500+ MW farm footprints, coordinating multiple crews across hundreds of hectares simultaneously.
Group-level relationships with panel, tracker and inverter manufacturers — securing supply at the lead times and volumes utility-scale projects require.
Regional employment, First Nations participation and community engagement built into every project from the planning phase — not added as an afterthought.
BESS Co-location
Battery energy storage co-located with solar is the fastest-growing combination in the Australian market — and one where having a single EPC contractor across both assets materially reduces risk and interface complexity.
Grid Connection
We routinely deliver the grid connection substation and overhead connection line as part of the same EPC contract as the solar farm — saving the developer a separate procurement round and eliminating interface risk between contractors.
Whether you're at EOI stage or ready to tender a full EPC package — including BESS and grid connection — our team can engage early and add value from the first conversation.
