Offshore energy transmission and interconnectors
Interconnectors, which are of crucial importance for the energy system of the future, represent a large and complex undertaking for electrical grid and infrastructure developers.
Arup has been involved with some of the world’s largest and longest HVAC and HVDC subsea interconnectors, providing comprehensive services across all project phases. This includes detailed design advice, programme and project management, procurement, construction management and due diligence.
Thanks to this level of experience, Arup is well-placed to solve the complex development challenges. In partnership with clients, we identify and proactively mitigate project risks using financial modelling and sensitivity and scenario analysis.
Our breadth of electrical and marine engineering experience means we can provide a suite of coordinated services for offshore electricity infrastructure. We have also acted as technical and financial advisor on competitive offshore transmission regimes, providing asset due diligence for investors.
Our team of advisory and engineering specialists assisted Equitix Limited and TEPCO Power Grid Incorporated (ETEPCO) to successfully acquire the Triton Knoll offshore wind farm transmission assets through the Offshore Transmission Owner (OFTO) regime.
Our multidisciplinary team was able to support ETEPCO across the structural and power systems engineering and planning, advisory, geotechnical and consenting elements of the Triton Knoll wind farm transmission asset project. The assets included one onshore and two offshore substations, as well as the export cables. As a result of our work, these assets were acquired with minimal risk.
