Company Description

Start here. Grow here.

The Transmission & Distribution (T&D) Engineering team provides a range of services from the initial concept through Power Systems Analysis, Cabling, Substations, Transmission and Distribution Infrastructure, System Balancing and Compensation, Protection Systems, SCADA, Communications, Converter Station Design, HVDC Systems and Interconnectors including overseas links.

Job Description

Here’s what you’ll do:

In this crucial role, you will be a key member of our Transmission & Distribution team dedicated to leading and engaging with our clients to deliver technically challenging OHL design projects.

Your primary focus in the role of Principal OHL Engineer is to provide project technical support and responsible for design of transmission projects. This team will work on various projects encompassing overhead transmission lines up to 400kV.

• Provide technical support in delivering overhead line design on complex multi-discipline projects.
• Have the opportunity to be involved in large programmes of work like GGP projects.
• Support in writing proposals and outlining all project details, including the timeline, resources, budget, objectives, and goals.
• Provide technical support and input throughout the project implementation, statutory planning, and participation in public consultation events.
• Be responsible for design activities related to the overhead line. This encompasses PLS-CADD modelling, meticulous line routing, comprehensive structural analysis and loading trees, formulation of design criteria, precise sag-tension calculations, insulator/conductor blowout, swing angle, damper system recommendations, strategic structural spotting, thorough clearance reports, and judicious conductor and insulator selection.
• Support in feasibility studies, performing conductor thermal ratings, and ensuring compliance with industry standards and regulations.
• Conduct studies to identify a technically preferred solution/layout to present to the client.
• Originate and check engineering deliverables such as complex designs, reports, proposals, presentations, and drawing packages.
• Perform internal quality checks of engineering drawings and calculations.

Qualifications

• Bachelor’s degree in Engineering (Civil, Structural, Mechanical, or Electrical Engineering) is essential.
• Experience delivering projects for transmission system operators such as National Grid, SSE and SPT in line with each operator’s standards.
• Project experience in overhead line engineering (ideally up to 400kV).
• Chartered or Professional Engineer status (or working towards it) is preferred.
• Proven ability to coordinate across disciplines and review detailed technical outputs to a high standard.

Technical Software and Delivery Capability

Expected to be proficient in key software tools used for transmission line design and capable of overseeing or guiding their application across various project scenarios. While certain tools are essential for core design tasks (e.g., PLS-CADD and PLS-TOWER), familiarity with a broader suite of structural, geotechnical, and drafting software is beneficial to support multidisciplinary coordination and delivery efficiency.
