Betolar, a 32-person Finnish materials technology company, announced on April 1 that it has developed a physical perimeter security solution for electrical substations, designed to protect them from drones and other threats. The announcement landed four days after a Ukrainian AN-196 Liutyi drone with a 6.7-meter wingspan and an unexploded warhead crashed north of Kouvola, Finland, having strayed off course during an attack on Russian Baltic Sea oil terminals. Finnish F/A-18 Hornets tracked it but did not fire to avoid collateral damage. Finnish Prime Minister Petteri Orpo said the drones likely went astray due to Russian electronic jamming. Ukraine apologized. Nobody was hurt.
The proximity is the story.
Betolar, based in Kannonkoski, Finland, a municipality of roughly 1,400 people in central Finland, posted EUR 946,000 in net sales in 2025 against an operating loss of EUR 5.84 million. It has 32 employees. It is listed on Nasdaq First North Growth Market in Helsinki and on the OTCQX in the United States. Its core business is low-carbon construction materials and metal extraction from industrial waste. Its financial target is positive EBITDA by the end of 2027. The company has filed a patent application related to the new solution and has announced no customers, no contracts, and no pilot deployments.
CEO Tuija Kalpala said in a press release that the deteriorating security environment requires preventive, scalable solutions and that protecting substations can enhance security of supply quickly and at reasonable cost. She is correct that the problem is real. North American utilities reported more than 3,500 physical security breaches in 2025, up from 2,800 in 2023, a tenfold increase over the past decade, according to the North American Electric Reliability Corporation. In November 2024, a Tennessee man was arrested for attempting to attack a Nashville substation with a drone carrying explosives. In December 2025, a San Jose engineer received 10 years in prison for a campaign of transformer bombings over 2022 and 2023.
Finland, which joined NATO in April 2023 and shares a 1,340-kilometer border with Russia, has already acquired hundreds of SkyWiper Omni Max drone jammers from Lithuania-based NT Service, deploying them around military bases and critical infrastructure. Those jammers create a protective dome that blocks the control, video, and navigation signals of approaching drones. But the AN-196 is a different class of threat: it is a one-way attack drone that flies pre-programmed autonomous routes using satellite and inertial navigation plus onboard terrain-matching, requiring no active signal that a jammer can reach. With a 1,000-kilometer operational range and a 75-kilogram warhead, it is designed to fly past electronic defenses and detonate on target.
The counter-drone market is responding to exactly this threat profile. Fortem Technologies, whose DroneHunter catches rogue drones in a net and drops them at a safe distance, was selected for the Pentagon's first operational purchase under the Replicator-2 program in January 2026. It is currently the only company authorized to deploy a kinetic drone-on-drone interceptor in U.S. civilian airspace, a regulatory moat that took years to build. DroneShield and Terra Drone are already active in substation protection. These companies have real customers, real certifications, and real fielded systems.
Betolar has a modular perimeter structure pitch, a patent filing, and a press release. Its announcement says the solution uses local low-carbon materials and is designed for rapid deployment and repairability under difficult conditions. It does not say what the system costs, when it will be deployed, or who has agreed to buy it.
The Kouvola incident credibly establishes that the threat is real, that autonomous drones can reach Finnish airspace without an operator-controlled signal, and that existing air defense responses are constrained when the rogue drone is not an immediate lethal threat to the intercepting aircraft. What it does not demonstrate is that a perimeter structure from a 32-person Finnish materials company is the answer. That answer requires customers, contracts, and fielded installations. Betolar has announced none of those things. The timing of its announcement, four days after an incident that made international headlines, explains why the announcement happened. Whether it solves anything will take considerably longer to answer.
