Defense-Coded Energy Infrastructure Hardening (MoD Gap-Fill on Litgrid €382M)

Executive Summary

Lithuania already has substantial energy hardening underway. In September 2025 Lithuania, Poland, Estonia and Latvia launched a joint €382M program led by the grid operators (Litgrid in Lithuania, PSE in Poland), roughly half funded by the EU's Connecting Europe Facility. Concrete blast walls are already in place at the Nemenčinė and Neris substations near Vilnius. A separate €113M EU grant supports Baltic and Polish grid resilience. In April 2026 a Polish company (APS) won a contract to install radar, jamming and counter-drone systems at Lithuanian energy sites, paid for by the energy companies themselves. And on 9 February 2025 Lithuania finished disconnecting from the old Russian-controlled BRELL frequency system and now runs on the European ENTSO-E grid. None of these programs, however, addresses the things only the armed forces can do. The gap is narrow but real, and Lithuania should study it on Lithuanian terms. The recommended next step is a joint working group between the Ministry of Energy, the Ministry of Defence and the National Cyber Security Centre, with input from Litgrid and Ignitis, to map exactly which energy nodes need military protection and to design an investment package on the order of €180M covering: a strategic reserve of high-voltage 330kV transformers (each takes 12 to 18 months to manufacture, so they cannot be procured during a war); microgrids for military bases and critical defence communications so they keep running when the civilian grid is down; a Cyber-Physical Repair Corps able to operate the grid manually when digital control systems are attacked; a written doctrine for using the territorial volunteer force (KASP) to guard substations during a crisis; force protection for the NordBalt, Bitėnai and Harmony Link landing points; and a hardening pilot against electromagnetic-pulse weapons. The exact scope, the procurement path and the legal authorities are decisions for the Lithuanian government and Seimas.

The Problem

Russia has shown it will systematically destroy civilian energy infrastructure. Ukraine's largest private power company, DTEK, lost 80 to 90 percent of its thermal generation by mid-2025 and was still down about 70 percent in January 2026. The threat is not one weapon but a mix, and protective measures that defeat one class do not defeat the others. Concrete blast walls work against Shahed-136 attack drones (50kg warhead) — the most common attack vector and the one the existing Litgrid program addresses. They do not work against an Iskander-M ballistic missile (700kg warhead), against Kalibr cruise missiles, or against the new KAB UMPB-5R glide bombs which can be launched from inside Belarusian airspace at 130 to 200 kilometres' range. Vilnius is 35 kilometres from the Belarusian border, so the entire city sits inside the inner part of that envelope. Ukrainian interception rates against Iskander-M dropped from 37 percent in August 2025 to 6 percent in September 2025 after Russian software upgrades — a six-fold collapse. There are also threats absent from the Litgrid program entirely: Russian special forces walking up to cable landing points, cyber attacks that disable the digital control systems running power stations (as Russian hackers known as Sandworm did to two Polish stations on 29-30 December 2025 by stealing authentication certificates), and high-altitude electromagnetic-pulse weapons. Cable-attribution disputes compound the problem: in October 2025 a Helsinki court dismissed the Eagle S case for lack of jurisdiction, and in February 2025 Swedish prosecutors closed the Vezhen case ruling it accidental — so the legal regime cannot reliably distinguish sabotage from accident.

The earlier framing that Lithuania has no hardening today is wrong and has been replaced. The September 2025 €382M Litgrid program, the April 2026 APS counter-drone contract, the €113M EU grant and the February 2025 ENTSO-E synchronisation are all real, funded and partly already on the ground. What remains uncovered is defence-coded: a high-voltage transformer strategic reserve at fifteen-unit 330kV scale; military-base and defence-communications microgrids; a Cyber-Physical Repair Corps under the Ministry of Defence; a static-guard doctrine for the territorial volunteer force (KASP) at substations during a crisis; force protection for the NordBalt cable landing, the Bitėnai substation and the Harmony Link landing point; an electromagnetic-pulse and high-power microwave hardening pilot; an operational-technology segmentation roadmap with the National Cyber Security Centre and Ignitis; and updated wartime legal authorities. The September 2025 ministerial instant-engagement authority granted to Defence Minister Šakalienė covers airspace only — it does not cover ground infrastructure protection. The Energy Security Operations Centre sits in the Ministry of Energy, not in the Ministry of Defence, so any hardening package has to be designed across ministries, not inside one.

Without action: A sustained Russian campaign mixing ballistic missiles, glide bombs, cyber pre-strikes, and special-forces raids against an unhardened or Shahed-only-hardened Lithuanian grid would track the Ukrainian DTEK trajectory: 70 to 90 percent of thermal generation lost within months. Hospitals, water treatment, military communications and government continuity all go down together. Strategic defeat is possible without any territory changing hands. The political backdrop sharpens the case: President Macron's 2 March 2026 Île Longue speech named Germany, Poland, the Netherlands, Belgium, Greece, Sweden, Denmark and the United Kingdom as nuclear-deterrence partners — the Baltic states are absent from that list, though not explicitly excluded. The first Tusk-Macron Treaty of Nancy bilateral summit at Gdańsk on 20 April 2026 did not include Lithuania. Sovereign hardening is what a country builds when it cannot rely on someone else's deterrent.
