Month-Ahead Long-Term Capacity Calculation Results

On this page, you can download the results from the Month-Ahead process of the Long-Term Capacity Calculation (LTCC) project.

For each scenario considered in the process, the published results include:

• Available Transmission Capacity (ATC) values for the DK1–DK2 bidding zone border
• Flow-based (FB) calculation parameters for the Nordic Capacity Calculation Region (CCR)

These results are published as part of the Transitional Solution, supporting transparency and enabling market participants to integrate long-term capacity insights into their planning and operations.

As the Long-Term Capacity Calculations are based on predefined scenarios, please note that the outcomes are also scenario-dependent and may differ from capacity calculations for other timeframes. The scenario-based approach involves uncertainties, and the outcomes should be complemented with operational insights and risk management strategies to support sound decision-making.

Please find the publication handbooks for ATCE and Flow-based in the following link.
