Three interconnector operators have now consulted on rules for cross-border trading in the event the UK has a ‘no-deal’ Brexit from the EU or is otherwise excluded from the EU’s Internal Energy Market (IEM).
No-deal Brexit places GB outside it and that affects the day-ahead market. Within the IEM, interconnector capacity is allocated ‘implicitly’ when power is contracted that must flow across it. Outside the IEM, capacity may have to be acquired separately (‘explicitly’). So far interconnectors have set new rules for day-ahead allocation.
