Why this analysis? From lessons of last winter to priorities for winter 2026/27

• Last winter 2025/26 exposed both the vulnerability and resilience of Ukraine’s energy system. Despite heavy Russian attacks on electricity generation, grid, heating and gas infrastructure, system collapse was avoided.
• However, the system remains highly vulnerable. Further attacks and limited dispatchable capacity mean that additional resilience measures are urgently needed before winter 2026/27.

This deck proposes 10 high-impact, no-regret measures for winter 2026/27:

• Focus on actions deliverable within ~6–8 months
• Not a comprehensive list – intended to stimulate policy debate and guide planning

Short- vs. medium-term trade-off:

• Many measures cannot be implemented before next winter
• Additional focus should be on policies that increase system resilience for 2027/28
