discussed. Since November 2017, exports to Scotland are limited to 80MW due to National Grid UK transmission constraints. However, two-day ahead projections of wind in Scotland are used to allow flows of up to 300MW. The 80MW constraint is expected to rise to 500MW by 2022. Moyle also provides frequency support services to both Eirgrid and National Grid. These services provide for fast change of power flow in the event of a network disturbance on either the NI or Scotland transmission systems.
