When modelling interconnection’s contribution to security of supply through the Capacity Market we de-rate them to ensure we have enough reliable capacity to meet peak demand. This process happens on an annual basis. National Grid models a range of different sensitivities to do this, taking into account conditions in those countries that we are interconnected to. This year the de-rating factors of several interconnectors were lower than in previous years, in part reflecting tightening margins in the countries that they connect to.
