Revised harmonised principles for Baltic LFC reserve prequalification
On 21 January 2021, an updated description of the concept for Baltic load frequency control block development and Baltic balancing capacity markets was published on the Latvian transmission system operator (TSO) Augstsprieguma tīkls (AST) website, which provides for the development of common qualification conditions for the resources used to provide the Baltic TSO Frequency Containment Reserves (FCR) and Frequency Restoration. Articles 155 (1) and 159 (1) of the European Commission Regulation 2017/1485 establishing a guideline on electricity transmission system operation require each TSO to develop an FCR and FRR prequalification process and to make publicly available the details of the FCR and FRR prequalification process.
On 11 November 2021, AST along with the other Baltic TSOs published the harmonized principles for Baltic LFC reserve prequalificationa and had begun public consultations, inviting market participants to state their opinions and answer the questions posed by the Baltic TSO's, regarding the harmonized principles.
During the public consultations, feedback was received from 5 market participants, resulting in The Baltic TSOs receiving 182 questions and comments on the Baltic LFC reserve prequalification harmonized principles. The Baltic TSOs have jointly reviewed the received questions and comments and have prepared answers to the market participants' questions and suggestions and have made the appropriate updates to the harmonized principles for Baltic LFC reserve prequalification.
The Baltic TSOs have begun work on preparing the national rules, in line with the harmonized principles for Baltic LFC reserve prequalification.
The Baltic TSO's prepared answers and the harmonized principles for Baltic LFC reserve prequalification are available for viewing in the documents below:
