TX Publishes Report into Export Cable Faults

12th May 2017

Transmission Excellence has completed a study (“Export Cable Reliability: Description of Concerns”) which shows how the rate of failures occurring on the high voltage submarine export cables which serve Britain’s offshore wind farms is higher than expected due to issues related to the optical fibres included within these power cables.

HVDC & Power Electronics Expert Joins TX

2nd May 2017

Transmission Excellence is pleased to welcome Emmanuel Amankwah who is joining to strengthen our capabilities in HVDC and power electronics.

Emmanuel joins from Nottingham University where he spent four years as a research fellow working on innovative improvements to HVDC technology. Prior to this he completed his PhD thesis on the design, simulation and control of a compact and efficient new converter topology.

Transmission Excellence Completes Cost Analysis

12th April 2016

Transmission Excellence has completed a study of how the cost of transmitting the power output of offshore wind farms to shore has varied over time. The study looks back to the earliest transmission-connected offshore wind projects and forward to far-offshore wind farms with as much as 170km of cable between the wind farm and the onshore grid.

The study, which was undertaken for the Offshore Wind Programme Board’s Grid Group, concludes that the industry has been remarkably successful in keeping per-MWhr transmission costs at a broadly constant level despite transmission distances increasing enormously. It also shows that, by applying technical advances identified by the Grid Group, it should be possible to maintain this success with future far-offshore projects.

Transmission Excellence Completes Important New Study

23rd January 2016

Working with ORE Catapult, Transmission Excellence has completed a detailed study of lightweight offshore substations. These are offshore substations that can be installed by the same vessels that are used to install the wind farm that they serve. They also sit on substructures that are adapted from those use by the wind turbines, and in some cases both substation and wind turbine can share the same substructure.

The report, which was undertaken for the Offshore Wind Programme Board’s Grid Group, concludes that this approach has the potential to reduce the cost of offshore wind by £1.7/MWhr.
