this is no longer true anymore since brexit. Electricity on spot market no longer has the same price in the whole country, it depends on which exchange you trade. this has been forbidden in the EU for a long time. There are more things that broke after brexit, hence the market coupling algorithm is much less efficient these days for the UK.
