They are at and Europe. And they are set to deliver much more. the heart of the transition to a smarter energy system. Tomorrow’s energy will be cleaner, more flexible and more responsive to the individual needs of consumers. To efficiently deliver the energy system of tomorrow, European countries are working together to maximise the potential of technologies £3 billion investment like battery storage, wind and solar power. Interconnectors Since 2014, over £3 billion has been invested in 4.4 GW of new enable smarter energy systems to react quickly to changes interconnector capacity, which will more than double the existing in supply and demand, ensuring renewable energy flows capacity between GB and continental Europe by the early 2020s. from where it is being generated in large quantities, to where it is needed most. Consumers benefit from interconnectors because they open the door to cheaper energy sources and Power for 11 million homes help GB build a smarter energy system. 4.4 GW of capacity provides access to enough electricity to power National Grid recognises 11 million homes. While the future relationship between GB and the EU the challenges that remains unclear, we are confident that we will continue Brexit poses. However, to trade electricity across interconnectors. It is in the best interests of all consumers for GB to keep working closely we remain confident 9.5 GW more that trade in electricity There is potential to increase the benefits to consumers through a with the EU to build an energy system that makes the best further 9.5 GW of interconnectors that will help deliver a smarter, more use of all our energy resources.

  • 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.
