We offer services across multiple disciplines and are experts in providing design from concept through to completion.
At Groundline, we're engineers first. For more than 20 years, we've specialized in transmission line and cable engineering across New Zealand, Australia, the UK, and the USA.
With deep technical expertise and real local knowledge, we solve complex engineering challenges and deliver solutions that stand up in the field, not just on paper. Behind every project is a team committed to keeping power moving for the communities that depend on it.
Whether you're planning, designing, or delivering critical energy infrastructure, we'd welcome the opportunity to help. Explore our work, meet our team, and see how Groundline can support your next project.
Groundline Engineering partners with network owners, developers, and independent connection providers worldwide to deliver reliable transmission and distribution solutions. Specializing in overhead power lines, underground cable networks, and engineering design services. We provide practical, high-quality support across the entire project lifecycle, from concept and design through to drafting and project delivery.
Overhead line design engineering is at the focus of what Groundline does. We plan optimal alignments for transmission lines across varied terrain, balancing engineering, land access, environmental, cultural, and constructability constraints to deliver practical constructable designs for transmission, distribution, and renewable energy projects.
Experts in underground cabling, Groundline delivers HV and EHV cable routing and system design for greenfield, brownfield, airfield and subsea projects. We combine cable design, route optimisation, system engineering, earthing and bonding design, and testing support to deliver reliable, efficient solutions.
Our exceptional team of CAD designers and drafters. Groundline delivers the technical drawings and digital models needed to support design, construction, and asset management. Using AutoCAD, MicroStation, Revit, Inventor, and PLS-CADD, we provide accurate, construction-ready deliverables.
Groundline provides specialist engineering design services to Independent Connection Providers (ICPs) operating across the UK's regulated electricity networks.
Structural design, Foundation Design, Verification & Design Assurance, Site Engineering & Construction Support, and Advisory: Built on experience not theory. All sit alongside our core design disciplines. These specialist engineering services support the full lifecycle of overhead line and underground cable infrastructure and distribution.
Foundation testing and engineering design are too often treated as separate line items, handled by different vendors, on disconnected scopes, with a handoff somewhere in the middle.
