With US President Donald Trump’s Power Day deadline looming, where he has promised to do “irreversible damage” to Iran's power grid, Russia has reportedly provided Iran with intelligence of the weaknesses of Israel’s power system for a possible retaliation.

Israel is an “energy island”, as it does not import electricity from any of its neighbors for national security reasons.

That means that some of the key distribution and generation facilities are very concentrated, making missile attacks on the system highly effective as they can cause major disruptions to the distribution of power to the country with just a few direct hits.

Trump moved a 48-hour deadline for “irreversible damage” to Iran’s power sector back to 8PM EST on April 7 (midnight GMT) after ceasefire talks started. Pakistan has floated a two-phase plan to impose a 45-day ceasefire. However, analysts are sceptical a deal can be done before the deadline expires and Tehran has already rejected the Pakistani proposal, countering with its own ten-point list of maximalist demands the same day that the White House is unlikely to accept.

Trump told journalists on April 6 that "the entire country [of Iran] could be taken out in one night. And that night might be tomorrow night."

Russian intelligence has reportedly provided Iran with a list of 55 critical energy infrastructure targets in Israel, according to The Jerusalem Post, citing a source close to Ukrainian intelligence. As IntelliNews has already reported, the CRINK alliance that includes Russia and Iran, are increasingly cooperating in the East-West class. Russian President Vladimir Putin has already admitted to sharing satellite intelligence with Tehran and Iran’s drones in the last year made the swap from using US-controlled GPS satellites for its guidance system to China’s BeiDou satellite navigation system which has improved their accuracy and negated Israel’s electronic warfare (EW) countermeasures.

The report says the information is shared data that identifies sites, categorised by strategic importance, ranging from critical production facilities to local infrastructure.

Among the highest-priority targets is the Orot Rabin power station, identified as a “Level 1” facility whose destruction could significantly disrupt national electricity production. A second tier includes major urban and industrial energy hubs concentrated in central Israel, supplying densely populated areas. A third category covers regional substations and smaller plants that support local industry.

According to the assessment attributed to Russian intelligence, Israel’s grid is particularly exposed because “unlike many European nations, Israel’s power grid is characterized by a high degree of isolation”. As a result, the report suggests that damage to a limited number of key facilities could trigger widespread and prolonged outages.

Ukraine’s intelligence services have been keenly focused on Russia’s ability to identify and destroy key power generating and distribution assets after Putin tried to freeze Ukraine into submission this winter by attacking Ukraine’s grid. During this year’s big freeze, Russia destroyed an estimated 80% of Ukraine’s generating capacity, sending temperatures inside some Kyiv apartments to under -5°C in the depths of winter.

Ukrainian President Volodymyr Zelenskiy has warned that military co-operation between Russia and Iran is expanding beyond the war in Ukraine.

“The Russians also helped them, like the Iranians helped [Russia] at the beginning of the war when they gave them Shaheds,” Zelenskiy told The Jerusalem Post in an interview on April 6. “They gained big knowledge on the battlefield and this will have an impact on other regions.”

Zelenskiy also said Russia had begun supplying Iran with domestically produced drones based on Iranian designs. “We saw some components; they had Russian details. We know it because Iranians didn’t produce it,” he said, referring to a drone reportedly downed in the Middle East.

Ukrainian officials argue that Moscow’s alleged intelligence sharing is intended both to strengthen a regional ally and to divert international attention from the conflict in Ukraine.

Russia’s ambassador to Israel, Anatoly Viktorov, rejected the claims. “Russia and Israel established contacts to discuss national security issues long ago. These contacts have been intensively maintained between relevant Russian and Israeli agencies. The most pressing issues have been discussed at the highest level. We value the track record which has been accumulated in this area,” he said. “Representatives of the Russian political leadership have repeatedly dissented from the ‘accusations’ that our country allegedly provides intelligence data to Iran,” he added.
