Baltics and Poland towards energy synchronisation

The transmission system operators of Lithuania, Latvia, Estonia and Poland submitted a funding application for a total of 1.2 billion euros to finance the project for synchronisation of the Baltic States with the Continental European Network. In particular, Lithuania’s share amounts to almost 40 per cent.

“This application marks the beginning of the second phase of synchronisation, which we are stepping into no longer as three countries, but as four – Lithuania, Latvia, Estonia and Poland,” commented Lithuania’s Minister of Energy, Žygimantas Vaičiūnas. “We have been laying the groundwork for this step for three years. The most important project for our energy independence is as close to the goal as ever and has the highest level of EU, regional and national consensus and support. Of no less importance is the fact that work in Lithuania has not stopped, even during this difficult lockdown period, continuing in full swing and according to plan.”

The lockdown, which has been in place for almost two and a half months, is not stopping the infrastructure work that is required for synchronisation. In fact, the government has approved 14 synchronisation infrastructure projects that have been granted the status of special national importance. 

In particular, the expansion of the 330 kilovolt (kV) transformer substation in Bitėnai in south Lithuania was completed in 2019. Construction of the 110 kV Pagėgiai-Bitėnai power transmission line is also nearing completion, a project that will also lay the foundations for the integration of wind farms. The project for optimisation of the north-eastern Lithuanian electricity transmission network and preparation for synchronous operation with the power system of continental Europe is also nearly three quarters done.

The most important and largest synchronisation project is the Harmony Link submarine interconnection. Today, Lithuanian and Polish TSOs Litgrid and PSE signed a cooperation agreement for the implementation phase of this project, according to which both parties undertake to contribute in equal parts to the installation of Harmony Link. The total value of the project will be approximately 680 million euros.
