KANNONKOSKI, Finland, May 22, 2026 /PRNewswire/ -- Betolar and Enersense have signed a letter of intent on commercial cooperation aimed at bringing solutions to market for protecting substations against external threats.
On April 2, 2026, Betolar announced its new solution for protecting critical infrastructure, such as electrical substations, and especially the main transformers. Enersense's strong expertise in the design, construction, and maintenance of substations enables the further development of the solution into an implementation-ready offering tailored to customer needs.
Practical Protection with Fast Implementation and Cost-effective solution
Betolar's solution is a modular and site-specific protective structure designed to improve the physical security of substations. The solution prevents unauthorized access and vandalism while protecting critical components from external impacts, including drone-related threats. The protective structure is designed for rapid deployment and local implementation. The solution can utilize low-carbon and resource-efficient materials such as locally available materials.
The solution leverages Betolar's expertise in material technology and has been designed with consideration for structural resilience against varying levels of explosive force. The solutions are suitable both for the construction of new substations and for the protection and upgrading of existing facilities.
The cooperation also covers the use of Betolar's low-carbon concrete and other sustainable material solutions in substation construction. This makes it possible to improve infrastructure safety while also supporting customers' sustainability and emissions reduction targets.
Growing Demand for Proactive Protection Solutions
Changes in the security environment are increasing the need for proactive protection of substations. At the same time, investments in Finland's transmission grid will grow significantly in the coming years, and at EU level annual investments in electricity grids are estimated to almost double by 2030. This development is particularly visible in the construction and modernization of substations and in the strengthening of their protection.
"Clean energy and a secure power grid are cornerstones of a sustainable society. As the security of substations is critically important to our customers, we want to help them identify effective solutions. Through our collaboration with Betolar, we can develop new protection solutions for our customers for both new and existing substations," says Juha Silvola, EVP, Power at Enersense.
"Protecting substations and their critical components requires proactive and practical solutions. Our collaboration with Enersense enables the further development of our solution for sites where operational reliability and security of supply are of significant societal importance. By combining Enersense's expertise in substations with Betolar's material technology, we can offer customers a scalable and cost-effective solution," says Tuija Kalpala, President and CEO at Betolar.
