Ukraine’s energy defence: how cogeneration and decentralized solutions are shaping a new model of resilience

As Russia turns Ukraine’s energy system into a target of daily strikes, the country is building a new model of resilience — based on decentralized generation and mobile cogeneration solutions. These technologies, capable of operating autonomously even during a complete blackout, are already forming “energy islands” for hospitals, water utilities, and district heating systems. In 2025, cogeneration has become one of the key tools of energy defence: from the rapid restoration of critical infrastructure to the creation of microgrids that withstand attacks where traditional generation can no longer cope.
