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.

  "summary": "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.",
  "narrative": {
    "dateline": "June 2030",
    "text": "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.\n\nOver 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.\n\nIn 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.\n\nReliable 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.\n\nThe 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.\n\nBy 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."
