By Newzino Staff | |

From 2022 missile barrages to record drone swarms, Moscow targets power, heat and transport as diplomacy stalls

January 20th, 2026: 145 drones and ballistic missiles strike amid minus 17°C cold

Overview

Since October 2022, Russia has waged a parallel war on Ukraine's electricity, heating and transport systems, launching repeated waves of missiles and drones at power plants, high-voltage substations, rail hubs and ports. The campaign has dramatically intensified in the winter of 2025–26, with near-daily massive barrages destroying 70% of Ukraine's generating capacity and forcing the government to declare a formal energy emergency on January 15, 2026. The grid now meets only 60% of national electricity needs, leaving millions without heat or power amid temperatures as low as minus 20°C.

The December 23, 2025 assault—635 drones and 38 missiles—marked the first time Russia targeted the 750 kV backbone substations that form the spine of Ukraine's grid, followed by an even larger barrage on December 27 (~500 drones, 40 missiles) and repeated attacks in January 2026 that have killed energy workers, damaged the Zaporizhzhia nuclear plant's last backup power line for the 12th time, and prompted an unprecedented IAEA-brokered localized ceasefire for emergency repairs. With available capacity fallen from 33.7 GW pre-war to just 14 GW by January 2026, Ukraine's energy minister warns there is 'not a single power plant left that the enemy has not attacked,' underscoring how energy vulnerability, nuclear risk and fragile diplomatic efforts remain tightly intertwined.

Scenarios

1

Protracted ‘energy attrition’ with a fragile but functioning grid

Discussed by: Ukrainian officials, European energy analysts and think tanks such as the European University Institute

In this scenario, Russia continues high‑volume winter attacks on Ukraine’s energy system but at a pace Ukraine can partially absorb through repairs, imports and rationing. Ukrenergo and DTEK patch together capacity, ENTSO‑E imports grow, and rolling outages become a normalized feature of Ukrainian life each winter. Civilian hardship remains severe but not decisive militarily; frontline positions change slowly while the ‘energy war’ settles into a grinding stalemate.

2

Western air defenses and grid aid blunt Russia’s winter campaign

Discussed by: Western governments, Ukrainian leadership, and military analysts

Here, accelerated deliveries of Western air defense systems, radars and munitions, plus large‑scale donor financing for transformers and high‑voltage equipment, significantly increase Ukraine’s interception rates and repair capacity. The March 2024 and December 2025‑type barrages become harder for Russia to repeat as its missile and drone stocks are depleted and Ukrainian strikes on Russian refineries and ‘shadow fleet’ tankers erode Russia’s ability to fund and fuel its long‑range campaign. Blackouts still occur, but less frequently and for shorter duration, reducing Moscow’s leverage.

3

Energy terror plus corruption fatigue drive pressure for a compromise peace

Discussed by: Political commentators in Europe and North America; some U.S. and European policymakers

Sustained infrastructure destruction, combined with corruption scandals in Ukraine’s energy sector and slower Western aid, could increase Ukrainian public fatigue and Western doubts about long‑term support. In this scenario, U.S.‑brokered talks—such as those underway in Florida in late 2025—gain momentum around a ceasefire and partial territorial concessions in exchange for security guarantees and reconstruction funds. However, domestic opposition in Ukraine and skepticism about Russian compliance could make such a deal fragile or unsustainable.

4

Major nuclear or dam incident triggers regional crisis and harder red lines

Discussed by: IAEA officials, nuclear safety experts, some NATO and EU policymakers

A worst‑case scenario involves a successful strike or cascading grid failure that causes a serious incident at Zaporizhzhia or Chernobyl—such as prolonged loss of cooling power, structural damage, or significant radioactive release—or at another major dam or hydropower facility. Even without a full‑scale meltdown, contamination or flooding could force mass evacuations and push NATO and the EU to set much harder red lines on attacks near nuclear and critical water infrastructure, potentially including new sanctions, air defense commitments near borders, or limited protective measures.

5

Russian long‑range strike capacity degrades, reducing intensity of future winters

Discussed by: Military intelligence assessments, open‑source defense analysts

Ukraine’s ongoing campaign against Russian refineries, fuel logistics and ‘shadow fleet’ tankers, combined with sanctions and production bottlenecks, may gradually reduce Russia’s ability to sustain huge missile‑drone salvos. Over time, Moscow could shift to fewer, more selective strikes, easing pressure on Ukraine’s grid. However, as the December 2025 barrage shows, Russia still retains substantial stockpiles and can surge attacks around key diplomatic or political moments, so this scenario likely unfolds over several years rather than one winter.

6

Complete grid collapse forces mass evacuation and international intervention

Discussed by: Energy security analysts, UN humanitarian officials, European emergency planners

If Russia sustains its current pace of strikes—now targeting the critical 750 kV backbone substations—Ukraine's grid could suffer cascading failures that emergency imports and repairs cannot offset. With capacity already at 14 GW (60% of need) in mid-winter, a complete collapse during subzero temperatures could force mass evacuations of major cities and trigger international humanitarian intervention, including emergency power-generation deployments by NATO members and potential establishment of protected energy corridors.

7

IAEA-brokered nuclear safety zones expand as Zaporizhzhia risks mount

Discussed by: IAEA Director General Rafael Grossi, nuclear safety experts, diplomatic officials

The unprecedented January 17, 2026 localized ceasefire for ZNPP backup power line repairs could serve as a template for broader safety arrangements. After the plant's 12th blackout, international pressure may force Russia and Ukraine into IAEA-monitored exclusion zones around all nuclear facilities, backed by enhanced monitoring and guaranteed repair access, reducing nuclear accident risk but effectively freezing territorial status around occupied sites.

Historical Context

1991 Gulf War: Allied bombing of Iraq’s electricity system

January–February 1991

What Happened

During Operation Desert Storm, U.S.-led coalition aircraft systematically targeted Iraq’s power plants and grid infrastructure. Attacks such as repeated strikes on the al‑Hartha power plant near Basra shut off electricity, water pumps and sewage systems for millions of civilians, leaving the country largely without power for weeks and reducing generation to roughly 20–25% of pre‑war capacity.

Outcome

Short Term

Allied forces achieved rapid military objectives, but Iraq’s civilian population endured severe hardships, including contaminated water supplies and increased disease and infant mortality due to disabled electricity‑dependent infrastructure.

Long Term

Iraq’s power sector never fully recovered before the 2003 invasion, remaining under‑invested and unreliable. The campaign became a reference point in debates about the legality and morality of striking dual‑use infrastructure and the long‑term humanitarian costs of such strategies.

Why It's Relevant Today

This precedent illustrates how targeting a country’s electricity system can quickly disrupt water, sanitation and health services on a national scale, as Russia’s campaign has done in Ukraine. It also shows that even when framed as a way to pressure a regime or weaken its military, infrastructure attacks can produce humanitarian crises that outlast the war—parallels that inform legal and policy debates around Russia’s strikes on Ukraine’s grid.

1999 NATO bombing of Serbian power and fuel infrastructure

March–June 1999

What Happened

During the Kosovo war, NATO aircraft attacked Serbia’s power stations and fuel depots, temporarily knocking out much of the country’s electricity supply and forcing authorities and the military onto backup generators. NATO officials described the strategy as a way to degrade military command‑and‑control and pressure Slobodan Milošević, though it sparked controversy over civilian suffering and long blackouts.

Outcome

Short Term

The bombing campaign contributed to Belgrade’s decision to accept a peace agreement and withdraw forces from Kosovo, but at the cost of significant damage to civilian infrastructure and loss of life in some strikes, fueling later criticism and legal scrutiny.

Long Term

Serbia’s power sector recovered over time, but the episode became a benchmark for debates on ‘strategic’ bombing of infrastructure and proportionality in modern air campaigns, often cited by both critics and proponents of using air power to coerce adversaries.

Why It's Relevant Today

NATO’s 1999 campaign shows that even Western democracies have targeted energy infrastructure to gain leverage in conflicts, a point Russian officials sometimes invoke to justify their own strikes on Ukraine. However, the scale, duration and winter timing of Russia’s campaign, combined with occupation of Ukrainian territory and attacks near nuclear sites, make today’s situation more akin to a sustained ‘energy terror’ strategy than to time‑limited coercive bombing.
