Britain has had to cut back on its practice of trading power with Europe to prevent blackouts at home, after the size and speed of its electricity trading put strain on the supplies of its neighbours.
The state-owned National Energy System Operator said it had put restrictions on the rate at which it can trade to reverse the flow of power between Britain and French, Danish, Dutch and Belgian markets after concerns emerged.
“NESO has been working closely with [officials, regulators and counterparts] over a period of several years in order to implement a process that maintains security in all interconnected regions,” it said in a notice to the market.
