Russia’s Baltic Exclave Goes Dark as Major Power Plant Failure Triggers Widespread Blackout

A major power outage swept across Russia’s Kaliningrad region overnight on October 30–31, leaving large parts of the Baltic exclave without electricity and disrupting mobile internet services following an emergency shutdown at one of the region’s largest power plants.

According to The Moscow Times on October 31, the blackout was triggered by the activation of an emergency protection system at Kaliningrad’s CHPP-2 thermal power plant, which caused some of its equipment to shut down.

The outage affected multiple districts of Kaliningrad and several surrounding towns, including Guryevsk, Svetlogorsk, Pionersky, Yantarny, Gvardeysk, and Bagrationovsk.

The affected power plant has an installed generating capacity of 900 megawatts, equivalent to approximately 54% of the region’s total installed electricity generation capacity as of 2019.

Mariam Bashkirova, spokesperson for the regional governor, confirmed that emergency protection equipment had activated at the facility. She said electricity demand had been redistributed to other regional power plants while crews worked to restore supplies.

Russian grid operator Rosseti stated that its regional subsidiary, Rosseti Yantar, had experienced no technical failures on its own infrastructure. The company said electricity was being restored in stages and expected all affected customers to be reconnected within an hour.

However, The Moscow Times reported that residents continued experiencing electricity interruptions despite those assurances. Some also complained of disruptions to water supplies and heating, with outages lasting from several minutes to several hours.

Kaliningrad is a Russian exclave located between Poland and Lithuania, geographically separated from mainland Russia and home to more than one million people.

In February 2025, the Baltic states disconnected their electricity networks from Russia and Belarus and synchronized with the continental European grid. Since then, Kaliningrad has operated its electricity system independently, relying on its own power generation infrastructure to maintain supplies across the region.
