National Grid IFA2 Ltd, in conjunction with land owner Fareham Borough Council have appointed leading consultants Arcadis to carry out an independent assessment looking at how the IFA2 electricity interconnector would operate alongside the Solent Airport at the Daedalus site in Lee-on-the-Solent, Hampshire. National Grid IFA2 Ltd is proposing to lease land at Daedalus for the British part of its proposed IFA2 project, which would help boost access to safe, reliable, affordable energy supplies by providing a new energy link with France. Arcadis have been commissioned to carry out the assessment to ensure that the interconnector will be able to coexist with site owner Fareham Borough Council’s Vision for Daedalus and won’t adversely affect operations at the airport. Arcadis will start work on their assessment this month with the report due to be completed in September 2016. Morris Bray, from National Grid IFA2, who helped commission the assessment, said: “This independent assessment should help provide reassurance that our proposals won’t affect Fareham Borough Council’s Vision for Daedalus including its continued use as an operational airport.” Stef Scannali, Arcadis Head of Safety Risk Management, said: “We’re delighted to be supporting National Grid IFA2 Ltd and Fareham Borough Council on this vital project.

  • North Sea Link

    North Sea Link

    NSL December 20 Update North Sea Link (NSL), a joint venture between National Grid and Statnett, is a 1,400 MW HVDC interconnector that will directly connect the electricity systems of the UK and Norway for the first time when it goes live in Q4 2021. Over the past few months, construction teams on both sides of the link have been working tirelessly to ensure that the project remains on track: UK- Blyth At Blyth, there are a number of key milestones which have already been achieved including the Substation connection works and all HVDC connections from the Converter Station to the landfall. At this very moment, HV equipment is being installed at site at a rapid rate of progress. With only a few key construction milestones left at Blyth, it is forecasted that the Converter Station here shall be completed in Spring 2021. Once complete, the Converter Station will undertake a series of testing and commissioning before go-live later next year. Norway – Kvilldal Progress in Kvilldal mirrors that in Blyth, with the connection to the Substation now being complete. This has allowed Kvilldal to complete their Statcom test program last month, ahead of schedule. As we move into 2021, focus turns to cable installation across the North Sea, especially the remaining sections towards the Norwegian border. Access Rules Consultation Thank you to all who responded to the recent Access Rules Consultation which closed on 1st December 2020 (see here). Moving forward, we are now preparing a consultation report for Ofgem which describes the responses that we’ve received and how we propose to deal with these.

    MEDOW Training Event

    MEDOW Training Event 10/12/2013 BritNed converter station in Kent Prepared by : Gen Li and Tibin Joseph As a MEDOW training event, we visited the HVDC converter station of BritNed in Kent on 10th December. It is an updated one compared to the UK-France HVDC cross-channel converter station at National Grid’s Sellindge Substation, we visited in the morning that day, because it was fully operated in the April 2011 but the latter one was in 1986. The electrical devices and technologies are more advanced for the rapid and ongoing development of the electrical power system. Figure 1 shows the schematic diagram of this project. Figure 1 The design concept of the BritNed project [1] The basic principle of this system is: the AC power from Netherlands will be converted to DC power at the converter station in Maasvlakte, Netherlands, then the DC power will be transmitted through the submarine HVDC cables to the Kent converter station, at last the DC power will be inverted to AC power and transmitted into the Great Britain power grids. The construction of this subsea interconnector required careful planning and precise execution. BritNed worked with its construction partners as one single team to safely design, manufacture and install the BritNed Interconnector to high standards of civil, marine and electrical engineering. The construction comprises three major components: 1) Manufacturing of the subsea cable and corresponding cable installation; 2) Civil construction of two converter stations; 3) Manufacturing and installation of the required electrical equipment and components in the converter stations [1]. During the visiting， the operators there took us around the main equipment, such as the huge Siemens single-phase power transformer, the LCC converters and circuit breakers in the converter halls and filter yard installed in this station.
