NCC approved the Terms, Conditions and Methodologies on Cross-Zonal Capacity Calculation, Provision and Allocation with the 3rd Countries


On 13 December, 2018 NCC approved the Terms, Conditions and Methodologies on Cross-Zonal Capacity Calculation, Provision and Allocation with the 3rd Countries (Methodology) which was prepared and agreed by Litgrid AB together with Latvian and Estonian transmission system operators.This Methodology is interrelated with the Capacity Calculation Methodology within the Baltic Capacity Calculation Region and also implements the requirements of Commission Regulation (EU) 2015/1222 establishing a guideline on capacity allocation and congestion management.

Also on 22 October, 2018 Latvian, Estonian and Lithuanian NRAs by common letter to Latvian, Estonian and Lithuanian transmission system operators indicated that Methodology is a necessary step towards further development of the cross-border capacity calculation and allocation with the 3rd countries.

The Methodology establishes the rules for calculating the cross-zonal transmission capacity of the transmission system between the Baltic States, as well as the Lithuanian energy system and the Russian (Karaliaučius) region and Belarus. In Methodology a guaranteed 200 MW capacity on Lithuanian-Belarusian border is terminated, i.e. the capacity on Lithuanian-Belarusian border will depend on the intensity of utilization of the electricity transmission system on the Latvian-Estonian border every hour.

The methodology will come into force on 1 of February, 2019.
