Imports are expected to account for a fifth of Britain's electricity demand as the country's energy department said it would build new power links with Europe, AFP reported.
The four connected lines between the UK and Ireland, France and the Netherlands currently have a capacity of 4 gigawatts, about 6 per cent of the UK's electricity supply, according to official UK data.However, the government expects imports to provide more than a fifth of the UK's electricity needs by 2025, thanks to 11 new transmission lines planned and under construction between the UK and European countries.
State grid owns three of the 11 new power lines.The company believes that power interconnection is good for consumers, with new transmission lines allowing the UK to even have access to electricity from Africa, and lower wholesale electricity prices on the continent will reduce UK household energy bills.
National grid also said connectivity was crucial to making electricity networks more flexible as more wind and solar power were put into use.One of the risks posed by brexit is that the prospect of cross-border energy deals is getting harder.In response, the brexit white paper highlighted the need for trade connectivity: " the trend towards connectivity has brought mutual benefits to trading partners."
It is expected that Britain's national grid and Belgium's interconnected power lines will be up and running by early 2019.The UK will then build a second electricity interconnection line with France in 2020, after which it will be the world's longest undersea cable interconnection in Norway.At the same time, other companies are building cables through the channel tunnel and plan to connect power interconnections to Germany.
