Baltic States and Polish transmission system operators submitted investment request of the Baltic states synchronisation project phase II to NRAs


en_cef__.pngThe Transmission System Operators of Electricity from Baltic States – Litgrid AB, Augstsprieguma Tīkls AS (AST) and Elering AS and Poland - Polskie Sieci Elektroenergetyczne S.A (PSE) submitted Investment Request of Baltic Synchronisation Phase II to the National Regulative Authorities of Lithuania, Latvia, Estonia and Poland.

The submitted investment request consists of the assessment of necessary investments in Baltic States and Poland, cost/benefit analysis of the Synchronisation Phase II and project business plan implementation. The total expected costs of Synchronization Project Phase 2 are ~1,2 billion EUR, where investments in Poland are estimated ~535.7 MEUR, In Lithuania – 474 MEUR, in Latvia – 99.5 MEUR and in Estonia – 110.6MEUR.

The key takeaways from the analysis is that the Synchronisation Project Phase II requires HVDC construction between Lithuania and Poland, internal network reinforcements in Lithuania and Poland, implementation of equipment for inertia and frequency regulation providing, as well as upgrade of electricity system protection and management schemes. All these activities are essential to prepare Baltic and Polish energy systems for secure and stable synchronous operation with Continental Europe.

The aim of Synchronisation project (consists of three phases) is to implement the necessary technical conditions for the synchronisation of the Baltic States' electricity grid with the continental European network (CEN) via Poland by year 2025.

Baltic States integration within the electricity system of European Union (EU) is recognized as a strategic goal and priority of the EU energy policy. The Synchronisation Project Phase II is logical continuation of Phase I, which received EU 75% co-financing from CEF grants in spring 2019.
