Nordic TSOs’ proposals for FRR and FRCE and frequency quality related methodologies

Overview

This consultation concerns the proposals of all Nordic TSOs for four methodologies related to Frequency Restoration Reserves (FRR), Frequency Restoration Control Error (FRCE) and frequency quality as required by Article 118(1) and 119(1) of the commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (SO Regulation). These methodologies include:
118(1)(z) and (aa): Methodology to determine limits on the amount of exchange of FRR/RR between synchronous areas defined in accordance with Article 176(1)/178(1) and the methodology to determine limits on the amount of sharing of FRR/RR between synchronous areas defined in accordance with Article 177(1)/179(1);
119(1)(c) Ramping restrictions for active power output in accordance with Article 137(3) and (4);
119(1)(h): FRR dimensioning rules in accordance with Article 157(1);
119(1)(q) and (r): Coordination actions aiming to reduce FRCE as defined in Article 152(14) and measures to reduce FRCE by requiring changes in the active power production or consumption of power generating modules and demand units in accordance with Article 152(16).  

The common proposals of the Nordic TSOs can be found below under the Related Documents.

Why your views matter

The proposals regarding the FRR and FRCE and frequency quality related methodologies for the Nordic synchronous area are subject to public consultation according to article 11 of SO Regulation.

What happens next

The TSOs of the Nordic synchronous area shall duly take into account the views of stakeholders resulting from the consultation and use them to prepare the final version of the document that will be submitted to the Nordic NRAs by 14 September 2018.

In all cases, a sound justification for including or not the views resulting from the consultation shall be provided together with the submission of the proposal and published in a timely manner before, or simultaneously with the publication of the FRR and FRCE and frequency quality related methodologies for the Nordic synchronous area.
