Pukenui Solar Farm

Phronis delivered electrical balance-of-plant and ancillary system design, including HV, LVac, LVdc and communications cabling, installation infrastructure and associated documentation. The scope also included revisions to piling, foundations and string layouts informed by PVSyst modelling and shading assessments, through to commissioning procedures and As-Built drawings.

The Scope

The project required coordinated electrical balance-of-plant design alongside integration with civil and structural elements such as piling and foundations. Electrical systems needed to incorporate HV, LVac, LVdc and communications cabling, along with associated installation infrastructure, requiring alignment across multiple disciplines.

Revisions to string layouts were required based on PVSyst modelling and near-shading assessments, introducing additional complexity in ensuring system performance while maintaining constructability and alignment with the broader design.

The scope also extended through to commissioning procedures and preparation of As-Built documentation, requiring continuity between design development, installation and final verification. Further detail on project-specific constraints or external challenges is not provided in the available information.

Our Response

Phronis developed electrical balance-of-plant designs covering HV, LVac, LVdc and communications cabling, along with supporting installation infrastructure. We coordinated revisions to piling and foundation plans to align with updated electrical and layout requirements.

String layouts were refined based on PVSyst modelling outputs and near-shading assessments to support system performance. Design development was carried through to preparation of commissioning procedures and As-Built drawings, ensuring consistency between design intent and installed infrastructure.

The work integrated electrical design with broader project elements, maintaining alignment across modelling, layout updates and documentation deliverables.

The Impact

The project delivered coordinated electrical balance-of-plant design and supporting documentation, including commissioning procedures and As-Built drawings. Updated string layouts informed by modelling and shading assessments supported alignment with system performance requirements.

Integration of electrical design with revised piling and foundation plans ensured consistency across disciplines and constructability of the installation. The completed documentation provided clarity for commissioning and verification of installed systems.

Specific outcomes relating to performance improvements, cost impacts or operational benefits are not detailed in the available information.
