Great Britain and Northern Ireland Regulatory Authorities Reports 2019 Publication 31 July 2019 Contact: Aidan Stringfellow, Manager date: Team: Wholesale Markets Tel: 020 7901 3085 Email: [email protected] Regulatory Authorities Report pursuant to section 5ZA of the Utilities Act 2000 and section 6A of the Energy (Northern Ireland) Order 2003. The Great Britain (GB) report covers: • Developments in the GB energy markets in the calendar year 2018 and the first six months of 2019. In some cases, data is only available for a subset of this period (i.e. the 2018 calendar year only). Where this is the case, it is clearly stated. • The regulation and performance of the GB electricity and gas markets along the themes of network regulation, promoting competition, and security of supply. • Our compliance with the Electricity and Gas Directives on consumer protection and dispute settlement. Since GB energy markets have been fully liberalised and the regulatory structures in place for a number of years, this report is intended as an updated version of the submissions made since 2007. Finally, for further information on Ofgem’s wider activities, please consult our Annual Report.

Chair’s foreword The foreword for the 2019 National Report is the first I have written as Chairman of Ofgem. I took over as Chair towards the end of the period this report covers and am excited to be taking on the role at what is a pivotal time for the GB energy sector. The past year was a period of uncertainty, which included the ongoing discussions on the future relationship between the United Kingdom and the European Union. While we cannot predict the final outcome of those discussions, it is important to stress Ofgem’s ongoing commitment to working with our fellow regulators in Europe. Over the coming years we will continue to act in the spirit of cooperation that we have always tried to bring to our engagement with our European counterparts. We continue to believe that an integrated and liberalised European energy market provides benefits for consumers. A large amount of our work is influenced by developments in Europe, and over the course of the year, Ofgem has worked towards the timely and full implementation of the European Network Codes and Guidelines. We have continued to work closely with industry to deliver a set of methodologies for the implementation of guidelines on Capacity Allocation and Congestion Management, Forward Capacity Allocation, and the Connection Codes. We also continued our activities towards the implementation of the Electricity Balancing Guideline Regulation, the Emergency and
