Go-live of Nordic flow-based CCM delayed to Q1 2024

 18 November 2022

The project parties involved in the implementation of the flow-based (FB) capacity calculation methodology (CCM) in the Nordics confirm a delay of the project. Go-live will be, at the earliest, in Q1 2024. Simulation results from the external parallel run are expected in January 2023, at the earliest.

The Nordic TSOs and NEMOs have encountered challenges in conducting the external parallel run (EPR) according to schedule. This is due to the prolonged unavailability of the market Simulation Facility used to calculate results and also to stability issues in the coordinated capacity calculation. The former has caused an extended interruption of FB market simulations, while the latter has triggered non-compliance with National Regulatory Authorities’ key performance indicators.

Consequently, TSOs and NEMOs have reassessed the timeline and concluded that the earliest possible go-live will be Q1 2024.

Alternative solution will provide market results in early 2023

Due to technical issues, the Simulation Facility could not be used by NEMOs and TSOs in the second half of 2022. NEMOs are now offering an alternative solution for the EPR, which will mitigate the challenges caused by the unavailability of the Simulation Facility.

As soon as the Simulation Facility is back in operation, calculation support for the EPR will be retransferred back to this primary tool.

Preliminary indications place a possible start of the alternative calculation support at November or early December 2022. Stakeholders can expect the first available FB market results based on the alternative solutions in January 2023, at the earliest.

About the Nordic FB CCM project

The Nordic TSOs and the Nordic Regional Coordination Centre (RCC) are currently working to implement the flow-based calculation methodology (FB CCM) in the Nordics. 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 and implemented 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 grant approval, they have to refer the decision to the Agency for the Cooperation of Energy Regulators (ACER).

More information on the implementation of Nordic flow-based capacity calculation methodology is available on the Nordic CCM page at Nordic RCC website: https://nordic-rcc.net/flow-based/
