The Transmission System Operators of the Finnish-Baltic region (hereinafter referred to as the TSOs) have actively undertaken infrastructure projects with the aim of increasing capacities in the region and enhancing the regional gas system to better meet the transportation needs of market participants.
Historically Balticconnector northbound capacity has ranged between 55-60 GWh/day in winter and 65 GWh/day in summer. In the direction from Finland to Estonia, a capacity of 78 GWh/day has been offered, approaching the maximum transportation capacity considering the pipeline’s diameter and design pressure.
Enhancement of Latvia-Lithuania interconnection (hereinafter referred to as ELLI) allows for higher gas volumes to be transported across the region. The results of capacity calculations and transmission system operation modelling conducted collaboratively by the TSOs indicate that the technical capacity of Balticconnector interconnection point can be increased.
After the restoration of flows over the Balticconnector pipeline and once inspection and maintenance works in Estonian-Latvian system are executed, the base capacity will be increased in the EST-FIN direction to 70,5 GWh/day. Considering the planned regional maintenance works foreseen in 2024, the increased capacity can be offered for the market starting from October 2024.
The TSOs will primarily publish information impacting technical capacities as UMMs on the Inside information platform and update the technical capacities offered to market participants on the ENTSOG Transparency Platform.
