The Polish government has revealed that the country experienced a major attempt to disrupt its power grid at the end of December 2025, and came “very close to a blackout”. However, it successfully repelled the cyberattack.
The digital affairs minister says that “everything points to Russian sabotage” being behind the incident.
“In the final days of 2025, a large-scale attempt was made to hack the energy system,” said Energy Minister Milosz Motyka at a press conference on January 13.
It was “the most powerful attack on the Polish power system in years” but “was successfully repelled”.
“This is the first time we’ve encountered multiple attempts at attacks on individual generating sources – solar farms and even individual wind turbines,” explained Motyka. It “involved an attempt to disrupt communication between generating installations and grid operators across a large area of Poland”.
The role of renewables in Poland’s energy mix has risen significantly in recent years. They account for around 29% of all electricity generated in the country. That is often the case even in winter. On Monday this week, amid extremely cold, snowy weather, renewables provided 25% of Poland’s electricity.
Previous attacks on Poland’s power grid targeted large energy facilities or the transmission system, noted Motyka.
“We have not see this type of attack on smaller-scale renewable facilities before, but we can expect it to happen again,” he said.
Later, the Digital Affairs Minister Krzysztof Gawkowski addressed the attack during an interview with broadcaster RMF. When asked if Poland had “come close to blackout” during the incident, he confirmed it had been “very close”.
“The scale of this attack, the vector of entry and who was behind it indicate that it was a coordinated operation intended to deliberately cut off power to Polish citizens,” continued Gawkowski. “Everything points to Russian sabotage intended to destabilise the situation in Poland.”
However, the “Polish security services and the Polish institutions responsible for cybersecurity rose to the occasion”, added the minister. “We have well-prepared institutions and there is no need to panic; Poland is the most cyberattacked country in the European Union.”
Poland has in recent years suffered a series of so-called hybrid actions orchestrated by Russia, including both cyberattacks and physical acts of sabotage, as well as disinformation and propaganda campaigns.
Last week, Motyka revealed that hacker attacks on Polish energy infrastructure had increased during recent cold weather conditions, which have seen temperatures plummet to below -15 degrees Centigrade in many places and energy use surge to record levels. (Notes from Poland)
