132 damage to high-voltage grids and substations in key regions complicates the restoration of normal power supply to the population and industry. The further development of the Ukraine`s energy system inevitably requires profound transformations to ensure its resilience during periods of prolonged threats. Military events have demonstrated the critical importance of the ability of energy facilities to operate autonomously, without dependence on centralized nodes that are the first to be attacked. That is why modern approaches focus on creating a flexible energy supply architecture, where local solar power plants and small-scale generation networks will play a significant role. The change in priorities is also due to the significant damage to large-scale solar parks in the south and east of the country. The loss of some capacity has demonstrated the need to decentralize facilities and actively implement more robust, less vulnerable solutions. This applies to both private households and municipal institutions, where the installation of self-sufficient energy systems can provide critical facilities – hospitals, schools, evacuation centers – with stable electricity even in the event of grid outages. Another significant challenge was that traditional high-voltage power lines proved too vulnerable to military attacks. Their destruction led to serious disruptions in power supply, leaving many areas temporarily isolated from the power grid. Against this backdrop, solar energy storage systems, deployed directly at the point of consumption, became one of the few sustainable power sources capable of supporting critical infrastructure. Synchronization of Ukraine with the European energy system has reduced the risk of large-scale outages, but this does not eliminate the need for resilient domestic generation. Local solar energy production addresses the challenges of seasonal and regional fluctuations, allows for the rapid deployment of new capacity and ensures the availability of vital resources even under crisis conditions [7]. Finally, the transition to a decentralized energy model will foster new security logic: instead of relying on a few large facilities vulnerable to attack, the country creates a network of numerous small sources the destruction of which will not lead to
