Consultation of proposal for new technical requirements for FCR

The Nordic transmission system Operators (TSOs) have worked on an updated proposal for new harmonized technical requirements for the ancillary services FCR-N and FCR-D. The Nordic TSOs are now seeking comments and views on the updated requirements until April 11. The Nordic TSOs will also host a workshop on the topic on March 28.

Since 2019, the Nordic TSOs have worked together to produce a final proposal for new technical requirements for FCR. In 2021, the TSOs carried out a pilot phase in which providers were asked to perform tests to try to meet the proposal for new technical requirements. In connection with the pilot phase, the TSOs have collected the participants' experiences and views on both requirements and test procedures.

The technical requirements document has now been updated based on experiences from the pilot phase. We are now seeking comments and views via this consultation.

Summary of changes in the updated proposal for technical requirements for FCR

The changes can be summarized in three important parts.

  • Reduced number of tests. The test program is greatly shortened for both FCR-N and FCR-D. For FCR-D, the ramp sequence test has been modified to include deactivation and parameter switching tests.
  • Relaxation of the requirements. The requirements for the FCR-N have been softened somewhat by assuming a slightly higher frequency-dependent load in the system. It will also be possible to pre-qualify a scaled-down capacity if the performance requirements are not fully met. The requirements for FCR-D have been softened both in terms of performance and stability.
  • Clarified requirements for resources with limited energy reserve, LER. The requirements include, among other things, management of energy level (state of charge).

The structure of the documentation has also been changed. The previous versions included a separate supporting document. It has now been removed, and the key content has been merged with the requirements document.

Nordic workshop on March 28, 2022

On 28th of March, the Nordic TSOs will host a workshop to present and discuss the future technical requirements for the ancillary services FCR-N, FCR-D up and FCR-D down.

During the meeting, results and experiences from the tests performed during the pilot phase for the new technical requirements will be presented. We will also discuss the Nordic TSOs' revised proposals for new technical requirements.

The last day for feedback is April 11, 2022

The consultation is open until April 11th. Comments shall be submitted to Fingrid via email to reservit[at]fingrid.fi, with the subject “Consultation: FCR technical requirements”. Comments are welcome in Finnish or in English.

Based on the feedback, the Nordic TSOs will update the proposal for new technical requirements, if relevant. Thereafter, the Nordic TSOs will produce a legal methodology proposal based on the proposed requirements. The legal methodology proposal will be published for public consultation, and then submitted to the national regulatory authorities in the Nordic countries for approval.

Document for consultation attached.
