03Narrative

Dateline: June 2030

The campaign began in March 2029 and no single incident in it was an act of war. A data cable to the islands was cut by a dragging anchor, and the vessel's owner proved to be a company registered six weeks earlier. A fire destroyed a transformer depot; the men charged had been recruited through a messaging application. Satellite positioning failed across the eastern region for days at a time, and aircraft approach procedures, ambulance dispatch and farm machinery guidance failed with it. Drones closed the capital's airport twice in one month. Each incident was investigated and attributed some weeks later, and each attribution was disputed by accounts that had not existed a month before.

Over the same months the security service found foreign access in the networks of two electricity distributors and one mobile operator. It was removed where it was found. It was not found everywhere.

In the second week of February 2030 the adversary used what remained. Protection settings at eleven transmission substations were changed remotely while control room displays continued to show normal values. Supply failed across the capital and the two industrial provinces, which together produced half of national output. Mobile networks ran on batteries for about four hours. Card payments stopped. Core systems at the mobile operator had been wiped, so restoring power did not restore service.

Reliable power and communications returned after 72 hours. Engineers restored the grid by driving to substations and switching by hand, because remote control could not be trusted. Two repair vessels sent to a damaged interconnector turned back after unidentified drones followed them and an anonymous warning reached their insurer. For the next 30 days electricity was supplied on a published rota. Hospitals, water treatment and food distribution were served first and industry worked three days a week. Several hospitals found that their fuel contracts had assumed an outage of 24 hours.

The government did not name the state responsible for nine days. The intelligence assessment was firm but rested on sources that could not be published, and ministers judged that an accusation without public evidence would divide allies. During those nine days a forged cabinet memorandum circulated which appeared to show that neglected maintenance had caused the outage. A message passed through a third government offered restraint in exchange for withdrawal from a defence agreement. The offer was refused. Allies consulted, issued a statement and sent grid engineers and mobile generation, but agreed no collective measure.

By May 2030 services were normal. The costs that remained were of a different kind. Two foreign manufacturers deferred planned plants and insurers excluded state-backed sabotage from infrastructure cover. A parliamentary inquiry recorded that no minister had held authority over operators, the intelligence service and public communication at the same time. It also found that households which had kept water, a battery radio and cash managed the 72 hours with little difficulty, and that fewer than one in three had done so.

The dateline is illustrative, not a forecast. The narrative is hypothetical; the historical anchors below are real events.

04Summary

A hostile state conducts a deniable campaign below the threshold of war for 12 months: sabotage of subsea cables and energy assets, cyber intrusions, interference with satellite positioning, drone incursions and information operations. At the peak, reached over weeks, it activates concealed access to power and telecommunications systems. Areas producing half of national output lose reliable power and communications for 72 hours and essential services are rationed for 30 days. Attribution remains contested and threats to crews deter repair. The government must coordinate intelligence, operators and public communication, restore services by manual fallback and resist coercion without escalating before it can show evidence. Conventional invasion is outside this scenario.

05Historical anchors

EventDateWhat happenedCalibrates
Ukraine grid attacksDecember 2015, December 2016, 2022–2024On 23 December 2015 attackers used access gained months earlier to open breakers remotely at three Ukrainian distribution companies. About 225,000 customers lost power for up to six hours and operators restored supply by manual switching. A second attack in December 2016 cut part of Kyiv's supply for about an hour. From 2022 missile and drone strikes on generation and transmission imposed scheduled outages nationwide.The only documented cases of a state cutting power through access placed in advance. They show that manual restoration works within hours where it is still possible, and that an outage of 72 hours is well beyond what cyber means alone have yet achieved.
Volt Typhoon advisory7 February 2024The US Cybersecurity and Infrastructure Security Agency, the National Security Agency, the Federal Bureau of Investigation and partner agencies reported that a state-sponsored group had compromised the networks of communications, energy, transport and water operators in the United States. They assessed that the purpose was to enable disruption in a crisis and that access had been held in some networks for at least five years.Concealed access exists before any crisis and can stay undetected for years. It supports the Medium exposure for North America and the assumption that removal during the campaign is incomplete.
Kyivstar network attack12 December 2023A destructive attack disabled the core network of Ukraine's largest mobile operator, which served about 24 million subscribers. Mobile and internet services were lost for several days and some air raid warning systems and bank terminals failed with them. Ukraine's security service said the attackers had been inside the network for months.The telecommunications half of the peak. Restoring power does not restore a network whose core systems have been wiped, and services that depend on the network fail with it.
Baltic subsea cable damage17–18 November and 25 December 2024Two telecommunications cables, BCS East-West Interlink and C-Lion1, were damaged in the Baltic within a day of each other. On 25 December the Estlink 2 power cable between Finland and Estonia and several telecommunications cables were damaged, and Finland detained the tanker Eagle S. Estlink 2 was out of service for about six months.The campaign phase: damage by commercial vessels with disputed intent, slow legal process and repair of a power interconnector measured in months.
Nord Stream sabotageSeptember 2022Explosions on 26 September 2022 ruptured three of the four strings of the Nord Stream 1 and Nord Stream 2 gas pipelines in the Baltic. Sweden and Denmark closed their investigations in February 2024 without naming a perpetrator.Attribution of sabotage at sea can remain contested for years, which is the condition the scenario sets for the government's response.
Iberian blackout28 April 2025Spain and Portugal lost power across the peninsula within seconds, affecting tens of millions of people. Mobile networks, card payments and rail services failed during the outage. Most supply was restored within a day. Investigators found a technical cause and no evidence of attack.Restart times and the dependence of telecommunications and payments on power in an advanced grid. The scenario's 72 hours is longer because restoration is itself contested.

07Transmission channels

  1. 1

    Sabotage, interference and intrusions degrade cables, energy assets and positioning services piecemeal over 12 months and spread security services across several vectors.

  2. 2

    Slow and contested attribution prevents a proportionate response, and information operations turn each incident into a domestic dispute about the government's competence.

  3. 3

    The adversary activates concealed access in grid and telecommunications control systems; areas producing half of national output lose power and communications for 72 hours.

  4. 4

    Payments, water, fuel distribution and hospital care degrade within hours to days as backup power and battery reserves run out.

  5. 5

    Operators restore supply by manual switching because remote control cannot be trusted; threats to crews and vessels delay physical repair.

  6. 6

    Essential services are rationed for 30 days; industry works reduced hours and logistics slow.

  7. 7

    The adversary attaches demands to restraint; allies consult, but the gap between classified evidence and public proof limits collective action.

  8. 8

    Insurers and investors reprice infrastructure and location risk, and deterrence weakens where the campaign is seen to have gone unanswered.

13Rating rationale

RatingBand or levelWhy
Likelihood, two years3PossibleThe campaign is already observed across the exposed cluster: Baltic cable damage in 2024, drone incursions and airport closures in 2025. The rating is for the full event, which requires a blackout across half of national output. Outside Ukraine no state has yet used concealed access to that effect, although advisories in 2024 confirmed that access was in place. For a nation in the cluster the probability sits in the 1 to 5 per cent band; elsewhere it is lower.
Likelihood, ten years4LikelyOver ten years the conditions accumulate. Access placed in control systems persists for years, grids and telecommunications depend more on remote operation and each unanswered incident lowers the expected cost of the next. Ukraine's grid was attacked by cyber means in 2015 and 2016 and by missile from 2022. For an exposed nation a single activation within a decade falls in the 5 to 25 per cent band.
Systemic impact2ModerateThe event strikes one nation at a time and the direct output loss is national. Systemic cost arrives through higher insurance and security spending across the exposed cluster, interrupted cross-border cables and interconnectors and weaker deterrence. This is Moderate: band shifts in one domain in a few nations. The level would rise if the target hosted a global financial, cloud or semiconductor hub.
National impact4SevereEssential services set the level. Areas producing half of national output lose power and communications for 72 hours and services are rationed for 30 days, with payments, water and hospital care degraded. Security and social cohesion are also damaged, because the state is shown unable to protect ordinary life and attribution divides opinion. Physical destruction is limited and services return within months, which holds the rating at Severe and below Catastrophic.
ConfidencemediumAll three panel members agreed the impact levels and two agreed the likelihood bands. The campaign is well evidenced; activation of concealed access against a state not at war is not.

Source of scores: model-panel-v0.5. Confidence refers to the rating, not the scenario. Calibration sources are listed with the anchors above and on the scenario methodology page.

14Open questions

Contested assumptions for the panel to resolve.

  • Whether the likelihood should be published for the exposed cluster and not per nation, since the base rate across the 197 nations understates exposure in Europe, the Indo-Pacific and among Russia's neighbours.
  • Whether a 72-hour blackout across half of national output is the right Standard Severe peak, given that no state outside a war has yet experienced activation at that scale.
  • Whether an onset of weeks describes the event or only its peak. The record rates the peak; the campaign that precedes it lasts months.
  • How to rate a nation that is the author of a campaign and not its target.
