[13][14] National Grid initially announced that half of the link capacity would be restored within a fortnight, with full capacity being restored in March 2022. It was completed in 1986, and replaced the first cross-Channel link which was a 160MW link completed in 1961 and decommissioned in 1984. This means that additional converter design and equipment prototype development and testing would be necessary in the coming years. The electricity is then transported as Direct Current via high voltage transmission lines over distances of up to several thousands of kms. The Sellindge converter station joins Interconnexion France-Angleterre to the 2,000 MW HVDC interconnector which links the British and French electricity transmission systems.

It plays a vital role, increasing the UKs energy security, reliability and capacity by connecting with the French electricity transmission network to bring a number of benefits, including lower cost electricity, increased access to low-carbon energy and improved security of supply. The fire service said four crews remained at the seen "dampening down remaining hot spots" at 14:45 BST. [10] Repairs were completed by the end of February 2017. National Grid said the site had been evacuated, and there have been no reports of casualties. Voltage is distance. The interconnector, which has been operating since 1986 and imports largely nuclear-generated power from France when needed, had only been operating at half capacity due to repair work, according. A large fire at a key substation in the UK has forced the shutdown of one of the most important power cables that import electricity from France. However, most HVDC converters are connected as twelve-pulse bridges. The current 2,000MW link is bi-directional and the countries can import or export depending upon market demands, mostly depending upon weather conditions and availability of renewable energy on the British Isles, and French surplus of nuclear generation or demand for electric heating.
