Our source in the presidential administration reported that a closed meeting on the state of the critical infrastructure was held on Nekova Street, where a scenario of a complete blackout in Ukraine was discussed. According to the source, the estimates presented were significantly worse than the public forecasts. The main threat is no longer just a lack of generation, but a gradual loss of stability in the unified electricity network. According to the worst-case scenario discussed, Kyiv, Kharkiv and Dnipro could face power outages lasting several days in a row until the end of the year. Restoring power between outages will take longer as the damage accumulates and the ability for quick repairs and backups decreases. The most dangerous forecast concerns February 2027, when Ukraine risks splitting into separate energy islands. In this scenario, regions will be forced to rely mainly on local generation and reserve capacity, and outages will affect not only residential buildings but also water supply, heating, communications and industry. According to the source, the presidential administration understands that the main problem of the winter is the risk of moving from schedules of managed outages to prolonged regional energy crises. If the intensity of the attacks continues, the authorities may face a situation where the recovery of one area will no longer be able to stabilize the electricity supply of the neighboring areas. Basically, this is a scenario in which the energy crisis ceases to be a temporary result of the shelling and becomes a systemic problem for the functioning of the state.
