Britit rakentavat parhaillaan siirtoyhteyksiä vähän joka suuntaan, mikähän siellä on oikein visio? Ostaa halpa energia pois muilta markkinoilta? Jotenkin tuo loppu kuulostaa varsin optimistiselle visiolle vai onkohan siinä perää?
Kohta käytössä on 8.4GW yhteydet ja lisää on jo tulossa kohti Saksaa ja Tanskaa.
“In addition, a new interconnector between GB and France, which takes installed connections to France to 4GW, starts testing at the end of September. This new Eleclink interconnector actually goes through the running tunnels of the Channel Tunnel and was originally going to go live in early 2022. However, due to COVID the cables have been installed more quickly than anticipated because there are fewer trains using the tunnels.
“At Christmas GB will have 8.4GW of installed cables from other markets, meaning that around 25% of the electricity we need could come from overseas. This increases the likelihood of import volumes hitting new highs in the next few months. It also means that on Christmas Day this year we could be relying on foreign power to cook our turkeys.”
Currently GB imports from the continent are cheaper than home-generated power mainly due to the Carbon Price Support – a domestic top-up tax levied in addition to the UK’s carbon price – which ramps up costs for large electricity generators. The regulatory differences on transmission and balancing charges that embed a price advantage to EU market players are another reason for the cheap imports.
However, in the longer term, EnAppSys said Britain could become a net exporter of power as it increases its reliance on interconnectors. Two new interconnectors to Germany and Denmark, which are currently under construction, will add another 2.8GW of capacity by 2023-24.
Hewitt added, “In the long run, Britain will stop being a net importer of electricity as more offshore wind is built around its shores. During periods when GB has more low-carbon generation than it needs, it may decide to dump excess power into Europe. This could become an important factor in reversing the interconnectors and changing GB into a net exporter of power, perhaps as soon as 2025.”
Britain is becoming increasingly reliant on power from overseas, as it saw a record day for electricity imports on August 20.
