UK-Denmark electricity interconnector under consideration
The transmission system operators (TSOs) in Britain and Denmark are examining the possibility of building an electricity interconector linking the two markets.
National Grid and Danish counterpart Energinet.dk will begin pre-feasibility work "immediately" with a report to follow around the end of the year, the TSOs said on Monday.
The study will look into technical issues, project benefits, potential routes and landing points, the capacity of the cable and potential commissioning timetable.
The study will also look at the role of a new cable in supporting the touted North Sea super grid, which will connect offshore wind power and promote the trade of renewable generation (see EDEM 30 June 2011).
The Danish parliament recently passed legislation to ensure 50% of Denmark's electricity is generated from wind power by 2020 (see EDEM 23 March 2012) and preliminary hopes are that the interconnector may foster greater renewable supply integration .
Energinet.dk executive vice president Torben Glar Nielsen said both countries are planning for integration of comparatively high amounts of wind power over coming years. "Therefore, the study will also look at how the new cable would help both countries export and import renewable power," he said.
While the research study is in its infancy, National Grid European business development head Terry McCormick billed the interconnector proposal as a step towards greater supply flexibility.
"More interconnection with Europe supports the integration of renewable energy and gives us more options to balance our network in the UK. It could also meet European objectives of bringing more competition to the market," he said.
The UK operates three interconnector cables with Ireland, France and the Netherlands and is looking to build further capacity to the former two markets, National Grid said.
Projects to build new links with Belgium and Norway are ongoing.
Denmark has interconnectors in place with Norway and Sweden as well as Germany, is building a new interconnector to Norway and seeking to establish a link to the Netherlands. TF
