Transmission Line Design, Technical Leadership and Design Oversight
Lead the design and engineering of HV/EHV overhead transmission lines (typically 110kV-400kV+)
Develop and review key deliverables including route alignments, tower spotting, conductor and earth wire selection, and insulator configurations.
Define clearances, right-of-way requirements, and design criteria in accordance with applicable standards.
Provide technical input to tower loading calculations and structural design teams.
Lead PLS-CADD modelling and transmission line layout development for complex projects.
Oversee the full design delivery process across multiple projects, ensuring technical consistency, quality, and alignment with client requirements.
Undertake and/or approve full design reviews of drawings, models, calculations, and design packages prior to issue.
Provide final technical oversight of design documentation to ensure completeness, constructability, and coordination across engineering disciplines.
Transmission Line Calculations and Technical Studies
Perform and review key electrical and mechanical transmission line calculations, including:
o Electrical studies: ampacity, corona and radio interference, line impedance, shielding angle
o Mechanical studies: sag-tension calculations, conductor blowout, loading cases (wind, ice, temperature) and clearance verification.
o Structural interface: tower loading trees, load combinations, and coordination with structural teams for tower and foundation design.
Engineering analysis is typically performed using PLS-CADD, PLS-TOWER, or POLE.
Provide technical governance and review of complex design calculations prepared by other engineers, ensuring assumptions, methodologies, and outputs are robust and compliant.
Project Engineering, Team Leadership and Multidisciplinary Coordination
Support or lead engineering delivery of overhead line projects across multiple project phases.
Coordinate with structural, geotechnical, power systems, and environmental teams to deliver integrated solutions.
Contribute to feasibility studies, route corridor assessments, and technical evaluations to identify preferred transmission line layouts.
Provide technical input to proposals, project planning, and engineering deliverables.
Lead and manage engineering teams, including allocation of resources, prioritization of workload, and monitoring of deliverable quality.
Mentor, guide, and support junior and senior engineers, helping to develop technical capability, review skills, and career progression within the team.
Act as a senior point of contact for internal team, clients, and project managers.
Standards, Compliance and Technical Assurance
Ensure designs comply with relevant standards including IEC, IEEE, EN/British Standards, and National Grid or DNO specifications.
Participate in design reviews, technical verification, and internal quality assurance processes.
Construction and Field Engineering Support
Provide technical support during construction and installation phases, including:
Tower erection and foundation works
Conductor stringing operations
Resolution of site technical issues and field design adjustments
