On 1 March 2019, the Office of Gas and Electricity Markets (Ofgem) published a letter updating energy market participants on no-deal Brexit REMIT contingency arrangements. The letter covers three main areas: (i) monitoring and enforcement; (ii) registration; and (iii) data reporting. Ofgem currently has no further communications planned in advance of 29 March, but should circumstances change, it will act to provide the maximum clarity possible.
