24 Months Ahead Constraint Limits
This dataset contains constraint limits in megawatts for the main boundaries on the transmission system on weekly basis for 24 months ahead.
NOTE: As part of our ongoing efforts to align with data management best practices and improve consistency across datasets, the column ids in the below datafile will be updated on 9th September 2026 as follows:
24 Months ahead constraint limits:
GM+ SNOW5A → GM_SNOW5A
SSE+GRM → SSE_GRM
SSEN-S → SSEN_S
SSE-SP2 → SSE_SP2
