Our specialist project managers, designers, engineers and environmental consultants provide a range of expertise for substation and overhead line projects spanning site and route optioneering; engineering environmental feasibility and constraints; planning consent support; grid connection support; civil and electrical engineering design; smart grid solutions; and scenario analysis for sustainable energy systems for new urban areas.
High and Extra High Voltage Substation Design
We have extensive experience in high and extra high voltage substation design. We are experts in the procurement and project management of new substations and associated infrastructure. We advise on extensions or refurbishments of existing substations and transformer bund works.
Our expertise includes network studies; full secondary design; engineering design coordination and project management; environmental impact assessments; transport analysis; planning of electrical networks; architectural design services and fire engineering.
Overhead Route Design
We support front-end planning and environmental issues on proposed OHL (overhead line) schemes including permit applications; planning of infrastructure and electrical systems; power facility design and infrastructure; and electrical networks and communication.
We use PLS-CADD industry leading software as an integrated design and analysis tool, employing sophisticated three-dimensional terrain and engineering modelling to design and analyze all aspects of route selection. Our expertise covers three core engineering design elements:
Selection of the OHL route, taking into account route topography, available locations for OHL towers, tower and insulator capacities and cable clearances
Structural design of the towers and other supporting structures under operational and environmental loadings arising from the proposed OHL route
Cable design and selection
Strong track record
We have been supporting the Beauly-Denny transmission line, one of the largest infrastructure projects in the UK. We also successfully supported the project to connect the island of Aland to mainland Finland by sea cable. Our clients include ABB, Siemens, the UK National Grid, Vattenfall, Forewind, Balfour Beatty, Scottish Power Energy Networks, Central Networks, Scottish & Southern Energy and EDF Energy.
