Off-Site Power Restored to Zaporizhzhia Nuclear Plant After 15-Hour Blackout

The International Atomic Energy Agency (IAEA) confirmed that off-site electrical power was restored to the Russian-occupied Zaporizhzhia Nuclear Power Plant (ZNPP) on Saturday, June 6, concluding a dangerous 15-hour blackout.

Off-Site Power Restored to Zaporizhzhia Nuclear Plant After 15-Hour Blackout

External electricity was successfully restored to the Zaporizhzhia Nuclear Power Plant (ZNPP) on Saturday, June 6, ending a 15-hour total power failure. 

According to an official operational update released by the International Atomic Energy Agency (IAEA) on X, the ZNPP was reconnected to the external grid on Saturday morning.

Emergency generators engaged during critical outage

For 15 hours prior to reconnection, the station was entirely cut off from off-site electricity. During this window, the facility was forced to activate its emergency diesel generators to supply the necessary power to keep its six halted reactors safely cooled.

The IAEA disclosed that this event marks the 18th complete loss of off-site power at the ZNPP since the outbreak of Russia’s full-scale invasion of Ukraine. Analysts noted that this specific outage stands as one of the longest durations the plant has spent disconnected from the power grid, raising anxieties over backup fuel consumption.

While all six reactors currently remain in a cold shutdown state, a continuous and stable supply of electricity is legally and technically mandatory to prevent backup fuel exhaustion and avert a severe nuclear emergency.

Off-site power was restored to the ZNPP this morning after a 15-hour outage, when the site had to rely on emergency diesel generators for electricity to cool its six shutdown reactors.

IAEA brokers ceasefire for urgent grid repairs

IAEA Director General Rafael Grossi used the platform to reiterate his warnings regarding the structural instability of the regional electrical architecture. Grossi asserted that the latest blackout underlines the extreme fragility of the electrical grid and reinforces the absolute urgency of moving forward with scheduled power line repairs.

Zaporizhzhia Nuclear Plant Loses External Power Temporarily After Drone Strike

The IAEA said the Russian-occupied Zaporizhzhia Nuclear Power Plant lost off-site power for the 17th time since the start of the full-scale war after a drone hit a nearby substation. Backup diesel generators provided electricity until the connection was restored about 20 minutes later.

“The incident once again underlines the constant dangers to nuclear safety during the military conflict,” Grossi remarked following a similar, 20-minute outage just days prior on June 3, which was triggered by a drone strike on the nearby Nikopolska substation.

To safely address these systemic vulnerabilities, a localized, temporary ceasefire was successfully brokered between the Ukrainian and Russian sides via the direct mediation of the IAEA. The local armistice officially took effect on Friday, June 5, specifically designed to protect engineering crews tasked with conducting repairs on the critical “Dniprovska” high-voltage power line.

Grossi stressed that maintaining these strict zones of military restraint is vital to prevent catastrophic technical failures at the occupied facility in Enerhodar.
