in the time available before Prorogation. I will correspond directly with my noble
Friend.</del></p><p><ins class="ministerial">The latest figures on electricity supplied
by interconnectors are available in the 2019 ‘Energy Trends: Electricity’, published
by BEIS. In Q1 2019, net imports of electricity via interconnectors were 6.0 TWh for
the UK. This is equivalent to 6.4% of total demand over the period. In Great Britain,
as part of the Capacity Market process, National Grid Electricity System Operator
assesses how much capacity will be needed in the years ahead factoring in the risks
of particular technologies not delivering. This annual process includes an assessment
of how interconnectors should be derated to reflect the likely reliability of electricity
flow during times of stress. We then secure all the capacity needed through the Capacity
Market, ensuring we meet our reliability standard.</ins></p><p><ins class="ministerial">In
Northern Ireland, the Single Electricity Market operates as a single, shared wholesale
electricity market between Ireland and Northern Ireland, with electricity flows between
Ireland and Northern Ireland treated as internal flows. The Single Electricity Market’s
capacity remuneration mechanism is working well to ensure security of supply of electricity
in Northern Ireland.</ins></p>
