Lithuania to Build Drone-Proof Power Substation Near Kaliningrad

Lithuania is moving forward with plans to construct a key power grid substation with military-grade defenses near the Russian border, a project critical for synchronizing the Baltic states with the Western European power grid. The national grid operator, Litgrid, is designing the facility to withstand modern military threats, including attacks from explosives-laden drones, according to CEO Andrius Semeskevicius.

A New Era of Infrastructure Security

The Gizai substation, located about 30 km (19 miles) from the Russian exclave of Kaliningrad, is a crucial node for the Harmony Link interconnection with Poland. This project will complete the decoupling of the Baltic grids from the system they once shared with Russia and Belarus. The substation's location in the strategically sensitive Suwalki Gap has elevated security concerns within NATO, particularly following Russia's 2022 invasion of Ukraine and recent alleged sabotage attacks on German infrastructure.

"Previously, when designing our grid, we planned for natural disasters. Now, we think about all possible hybrid and non-hybrid threats," Semeskevicius told Reuters. The design reflects what he termed a "new reality" in regional security.

Fortified Against Attack

Litgrid is implementing a range of defensive measures to protect the 35-hectare site from a variety of potential attacks. The fortifications are being designed in consultation with the Lithuanian military.

• Drone Defense: Key equipment like transformers will be encased in reinforced-concrete "sarcophagi" designed to withstand the impact of drones carrying up to 100 kilograms of explosives, similar to the Shahed drones used by Russia in Ukraine.
• Physical Barriers: The plans include fencing strong enough to stop an explosives-laden truck and a perimeter designed to protect against projectiles like Molotov cocktails.
• Subterranean Threats: The facility will be equipped with sensors to detect any potential tunnels dug by hostile actors.
• Redundancy: The substation will have duplicate units of critical equipment to ensure operational continuity even if one part is damaged or destroyed.

"We cannot use simple concrete, it needs to be custom-made, for stronger resistance," Semeskevicius said, explaining that the concrete will be reinforced with plastic threads to prevent it from crumbling.

Securing EU Funding

The enhanced security measures are projected to add at least €48 million to the substation's cost, a figure that Litgrid warns could rise if the geopolitical situation deteriorates. Lithuanian Energy Minister Lukas Savickas stated that the country will ask the European Union to cover at least half of these additional costs, arguing they should not be borne solely by Lithuanian consumers.

This sentiment was echoed by Polish officials, who cautioned that forcing border states to shoulder the full bill for heightened security could harm their economic competitiveness. Wojciech Wrochna, Poland’s deputy energy minister, called for a change in mindset from European partners, stating, "The issue extends beyond Harmony Link. It affects the entire energy system."
