Nordic Capacity Calculation Methodology Project

The Nordic Capacity Calculation Methodology (CCM) project is responsible for the methodology development of the Nordic Capacity Calculation Methodologies for the Long-Term (LT), Day-Ahead(DA), and Intraday (ID) timeframes.

The methodologies are to be developed in line with the requirements from the Forward Capacity Allocation Guideline (FCA GL) and Capacity Allocation and Congestion Management Guideline (CACM GL), and to be approved by the National Regulatory Authorities (NRAs). If NRAs are not able to approve the methodology proposed by the TSOs, they have to refer the methodology to the Agency for the Cooperation of Energy Regulators (ACER). ACER will then amend, and decide on, the methodology.

Parallel run data

The external parallel run started on 7 March 2022 for the delivery day of 8 March 2022. For information on the available parallel run data, please visit Simulation results.

The 3-month NRA reporting period started on 12 December 2022

The quality of the External Parallel Run (EPR)-process is now sufficient for the 3-month NRA reporting period to start on 12 December 2022 (i.e. week 50). Market reports for weeks 50 and 52 are now available under Simulation Results. The project parties thank all stakeholders for your continuous support and highly-appreciated patience with the project. We are committed to continuing to improve the delivery of these results according to the regulatory KPI requirements.

The previously communicated go-live window - Q1 2024 at the earliest - remains unchanged.

Alternative solution to facilitate market simulations

Due to technical issues, the Simulation Facility could not be used for market simulations by NEMOs and TSOs from the second half of 2022. Instead, NEMOs are now delivering market results using an alternative setup for the EPR, mitigating the challenges caused by the unavailability of the Simulation Facility.
