New EU project to boost HVDC offshore grids

Tuesday, 15 March, 2016 - 11:30

The project “PROgress on Meshed HVDC Offshore Transmission Networks” (PROMOTioN) aims to investigate benefits a meshed offshore transmission grid could create. Currently it is the biggest energy project in the EU’s Horizon 2020 Research Programme.

PROMOTioN is funded under the EU Horizon 2020 Research Programme (H2020) from January 2016 until December 2019. The project consortium which is coordinated by DNV GL includes 34 partners from 11 countries – all major HVDC manufacturers, TSO’s linked to the North Sea, several wind turbine suppliers, offshore wind developers, leading academics, and consulting companies.  A series of stakeholder workshops and events will be organised during the project phase to discuss the various technological and regulatory approaches.

The goal is to develop and demonstrate three key technologies: diode rectifier offshore converters, multi-vendor HVDC (high-voltage direct current) grid protection system, and the full power testing of HVDC circuit breakers. Furthermore, a regulatory and financial framework will be developed for the coordinated planning, construction and operation of integrated offshore infrastructures, including an offshore grid deployment plan (roadmap) for the future offshore grid system in Europe.  

Currently, the high cost of converter technology, a lack of experience with protection systems and fault clearance components hamper the deployment of meshed HVDC offshore grids. In addition the deployment is hindered by limitations inherent to existing European regulations for the purpose of developing cross border offshore infrastructures, national legal and regulatory barriers and financing issues.

Marie Donelly, Director Renewables at the EU Directorate-General for Energy (DG ENER), said: “The Northern Seas offer unique opportunities for cooperation and to deliver cost-reduction to the offshore energy systems.  We think that an offshore grid in the North Sea could become a flagship project for regional cooperation as foreseen by the Energy Union.” 

Elisabeth Harstad, CEO at DNV GL, added: “Combining new HVDC technologies within present systems is instrumental in bringing large scale renewables into the grid and to ensure a future-proof grid which is affordable, reliable and sustainable.”

Rostock-based company EEW Special Pipe Constructions GmbH has received an order from the Swedish energy group Vattenfall to produce 41 monopiles for the 344 MW offshore wind
farms Vesterhav. The contract was signed on 19 November 2021.

The first of a number of transformers that will enable the transmission of renewable energy from the world’s largest offshore wind farm has been delivered. The transformers will play an integral role in the operation of three onshore convertor stations in East Riding of Yorkshire and on Teesside, that will eventually convert the current from the wind farm for transmission via the national grid network to 6 million UK homes.
