System constraints

On this page, you’ll find a map of outturn thermal constraint costs and also Day Ahead Flows and Limits of Thermal Constraints.

To give greater insight on balancing decisions, these reports provide outturn system costs for thermal constraints across a number of significant constraint boundaries.

We also provide a snapshot of the limits and flows at these boundaries at day ahead stage. Please note that these flows are a snapshot and will not reflect flow changes following publication of the report.
