A historic synchronization with Europe provides a roadmap for the EU's last energy-isolated state.
Energy resilience requires more than just technological solutions. It demands a long-term strategy that brings together political will, institutional cooperation, investment, and ongoing risk assessment.
Strong political will, backing from the European Union, and effective coordination among everyone involved made it possible to synchronize the Baltic electricity grids with the European system. While Cyprus remains the only energy-isolated member state of the European Union, leaving households and businesses burdened with high electricity costs, Lithuania, Latvia, and Estonia have successfully ended their energy dependence on the Russian and Belarusian grids. They are now fully integrated into the internal EU electricity market, connected to the continental European grid through Poland. This initiative, known as the Continental Europe Synchronous Area, had been an EU priority for nearly 20 years. It was finally achieved on February 9, 2025, through bold political decisions, essential technical work, and close cooperation among all parties.
Lithuania's Minister of Energy notes that effectively coordinating stakeholders was one of the biggest challenges of the project.
Costs and investments
Unlike Cyprus, where the drive for energy independence comes mostly from high electricity costs, Lithuania did not focus on lowering prices as the primary goal of joining the synchronized continental European grid. According to the electricity transmission system operator Litgrid, electricity prices were already low because the country remained fully connected to the Russian and Belarusian grids through the BRELL system until its energy decoupling on February 9. In fact, journalist Gytis Kapsevičius of the Lithuanian financial newspaper Verslo žinios mentioned that consumers actually saw their utility bills increase after the Baltic grids synchronized with the European system. Because of this, the operator pointed out that even though European funds covered most of the project, Lithuania still requires significant investment to ensure the new system runs reliably and meets future energy demands.
Litgrid executives stated that the regional electricity connections currently underway include Harmony Link, a second overland power link between Lithuania and Poland. It is expected to be completed by 2030 at a cost of roughly €400 million. The EstLink 3 connection is also in development, scheduled for completion in 2035 with an estimated price tag of €6 billion. Meanwhile, plans are moving forward for a fourth power link between Latvia and Estonia, along with an upgrade to the cross-border connection between Lithuania and Latvia, both targeted for completion by 2035.
The synchronization effort required around 40 individual projects, 20 of which were built in Lithuania. Total investments reached approximately €1.6 billion, with €1.2 billion funded by the Connecting Europe Facility, covering 75% of the investment costs.
The success story
Synchronizing the Baltic power grids with the European system was one of the most complex energy projects ever executed in Europe. The difficulty stemmed not just from the technical demands, but from the sheer number of stakeholders involved. Lithuania’s Minister of Energy, Žygimantas Vaičiūnas, explained that the project required coordination among Lithuania, Latvia, Estonia, and Poland, bringing together transmission system operators, regulatory authorities, national governments, and the European Commission. The minister told "K" that managing all of these entities effectively was one of the greatest hurdles in achieving a transition that broke away from reliance on Russia.
He also emphasized the intense technical demands of the project, noting that the Baltic nations had to disconnect from an electricity system they had relied on for decades and integrate into continental Europe's synchronized grid, all while ensuring the transition never compromised the security of the power supply.
The definitive political decision came in 2018 when the agreement to synchronize the Baltic states with the European grid was signed, setting a completion deadline for 2025. From that point on, he said, all efforts focused on executing the necessary technical infrastructure.
He added that installing modern synchronous condensers was a critical element of the design, playing a vital role in keeping the system running smoothly after synchronization. The power connections with Poland were equally vital to the project's success.
Cyprus and its challenges
Though Cyprus and Lithuania face distinct geopolitical issues, they share a common reality: the resilience of their power grid is central to national security. In Cyprus, energy isolation makes it even more urgent to build strong resilience policies, protect critical infrastructure, maintain sufficient power reserves, and strategically plan the island's future energy connection to Europe.
The experience of the Baltic nations can offer a helpful blueprint for shaping the energy strategy of Cyprus. As Lithuanian authorities pointed out multiple times, upgrading an energy system depends first on political decisions, strategic planning, and institutional cooperation, followed by technical execution. True energy resilience comes from a long-term strategy that unites political will, institutional cooperation, investments, and constant risk assessment, rather than technological fixes alone.
