IFA2 National Grid Land at Daedalus Airfield Lee-on-the-Solent PO13 9YA - 1,100MW electricity interconnector between GB and French transmission systems. IFA2 will use a High Voltage Direct Current (HVDC) cable for the connection between Great Britain and France. The electricity must be converted to and from HVDC and the High Voltage Alternating Current (HVAC) used in the domestic electricity transmission systems of Great Britain and France, and this requires a converter station in each country. Cables connect the converter station to a local substation, which transports the electricity onto the domestic network.
