Vilnius and Warsaw are moving quickly to safeguard a critical piece of the Baltic power network. The Gizai substation, slated for construction about 30 km west of Russia’s Kaliningrad exclave, will be the first new installation in the region since Russia’s full‑scale invasion of Ukraine in 2022.
Why the substation matters
The facility will serve as the cornerstone of the Harmony Link interconnection, linking Lithuania’s grid with Poland and, ultimately, the broader European Union. After the Baltic states decoupled from Russia’s electricity system last year, this link became the lifeline that ensures a steady supply of power should regional tensions flare.
Security measures against modern threats
Litgrid CEO Andrius Semeskevicius told Reuters that the design now accounts for “hybrid and non‑hybrid threats.” The plan includes a fence capable of stopping an explosives‑laden truck, sensors that can detect tunnels dug by hostile actors, and concrete “sarcophagi” that encase transformers to survive a direct drone strike.
Semeskevicius explained that a single military drone could only damage a limited portion of the 35‑hectare site, and that the distance of critical equipment from the perimeter fence is intended to protect against even a Molotov‑cocktail‑style attack.
“We are designing Gizai for a new reality… we are protecting ourselves from multiple Shahed drones, which could crash‑land with 100 kilograms of explosives,” he said. Shahed drones, supplied by Iran, have been used by Russia to target Ukrainian infrastructure, causing widespread power outages.
Redundancy and resilience
The substation will feature duplicate units of key equipment so that operations can continue if one set is damaged. Replacing the bespoke gear could take years, making redundancy essential.
Concrete used in the sarcophagi is custom‑made with plastic threads to reinforce it and prevent crumbling under blast pressure. The equipment will also be artificially cooled inside the sarcophagi, adding to the overall cost but ensuring reliability.
Funding the security upgrades
Lithuania’s energy minister, Lukas Savickas, said the project now costs at least €48 million more than originally planned. He will ask the European Union to cover at least half of the additional expense, arguing that the costs should not fall solely on Lithuania.
Poland’s deputy energy minister Wojciech Wrochna echoed the sentiment, warning that bordering Russia should not force neighboring countries to shoulder the entire financial burden. He urged EU partners to change their mindset and increase financing for grid security measures.
Regional context
The substation sits in the so‑called Suwałki Gap, a narrow corridor of land between Russia‑controlled Kaliningrad and Belarus that NATO has long identified as a strategic choke point. Recent sabotage attacks on Germany’s electricity grid, which Berlin blamed on Moscow, have heightened concerns about false‑flag drone operations designed to test NATO unity.
Intelligence sources told Reuters that Russia could attempt a false‑flag attack using drones to create the illusion of a third‑party perpetrator, thereby sowing doubt among NATO allies.
Looking ahead
Litgrid and Lithuanian military advisers are working together to finalize the physical security plan. If geopolitical tensions worsen, the cost of the project could rise further, but officials stress that protecting the power supply is essential for the safety and economic stability of the Baltic region.
