Baltic load frequency control block
In preparation for connecting Lithuanian, Latvian and Estonian electricity power systems to the synchronously operated area of the Continental Europe, three Baltic transmission system operators – Litgrid AB, AS "Augstsprieguma tīkls" and Elering AS – have signed Memorandum of understanding for Baltic Load Frequency Control (LFC) Block development in order to establish common principles for frequency and balance control of three Baltic power systems.
Taking into consideration that desynchronization of the power systems of the Baltic States from the synchronous area of IPS/UPS and their synchronization with the Continental Europe Synchronous Area (hereinafter referred to as CESA) requires Baltic TSO's to develop and start operating the LFC process pursuant to the Synchronous Area Framework Agreement of CESA and other relevant arrangements, Baltic TSO's have agreed to enter into Memorandum of understanding in order to highlight the key concepts, principles and actions to establish a framework for development of an effectively functioning Baltic LFC process, which will also open the Baltic power market for a new type of reserves and make it more attractive for the new market participants. The Memorandum envisages Baltic TSOs aim for the creation of a common reserve market in the Baltics, which will increase market liquidity and competition thus ensuring most eficient procurement of balancing capacities within Baltics.
As a result of Memorandum, Baltic TSO's will commonly develop the LFC Concept document for the key principles stipulated herein to be elaborated in due detail to cover necessary reserves as well as organisational arrangements for the LFC block cooperation which shall be consulted with the stakeholders. The public consultation is set to be conductued the autumn of 2020.
Based on the LFC Concept document the Baltic TSO's commit to draft and conclude all the arrangements and methodologies within the LFC Block Operational Agreement to comply with Article 119 of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation.These actions will be concluded before the synchronization of Baltic Power systems with CESA.
Baltic transmission system operators - AB „Litgrid“, AS „Augstsprieguma tīkls“ and AS „Elering“ (hereinafter – Operators) have prepared Baltic load frequency control block and balancing capacity market concept. Operators have prepared proposals for frequency and power balance control within Baltic LFC block, dimensioning of reserves and distribution between Baltic states and model for common balancing capacity market for connection to Continental European network. Concept document was submitted for public consultations from 30th of September to 30th of October 2020.
Baltic TSOs on 20th of January 2021 have prepared the amended version of Baltic Load Frequency Control Block concept considering the feedback and answers received from the stakeholders during the public consultations.
Response table for feedback of the stakeholders to public consultation is published additionally to amended Baltic LFC block concept.
Baltic TSOs will continue implementation of Baltic LFC block by preparing the implementation documents and methodologies as described in the roadmap until Baltic states connection to Continental European network.
