Saksassa syyskuussa tapahtuneet sähköverkkoon kohdistuvat sabotaasiyritykset kannattaa huomioida myös Suomessa, sotatieteiden tohtori, kokoomuksen kansanedustaja Jarno Limnell kirjoittaa X-viestipalvelussa.

Kolmessa saksalaisessa osavaltiossa tutkitaan sähköverkkoon kohdistuneita sabotaasiyrityksiä. Sabotaasista ovat kertoneet muun muassa uutistoimisto Reuters ja saksalaislehti Bild.

Sabotaasiyritykset ovat ”vakavia”, Limnell kommentoi.

– Nyt kannattaa katsoa yksittäisiä iskuja laajemmalle. Tämä on varoitus myös Suomelle.

– Kohteena on yhteiskunnan hermosto: sähkö, jonka varassa toimivat viestintä, liikenne, yritykset ja meidän arkemme, Limnell kommentoi.

Limnellin mielestä Suomen kannattaisi suojella omaa kriittistä infrastruktuuriaan entistä kokonaisvaltaisemmin.

– Kriittisen infrastruktuurin suojaamisessa on siirryttävä yksittäisten kohteiden vartioinnista koko järjestelmän toimintakyvyn turvaamiseen. Kaikkea ei voida suojata koko ajan. Ratkaisevaa on, ettei onnistunutkaan isku pysäytä yhteiskuntaa.
Drooni-iskuyritys lentokentällä

Sähköverkkoihin kohdistuvien iskusarjojen taustaa ei tiedetä. Saksan viranomaiset eivät ole sulkeneet pois valtiollisen toimijan mahdollisuutta, mutta kesken olevassa tutkinnassa ei ole ilmennyt näyttöä esimerkiksi Venäjän osallisuudesta.

Leipzig-Hallen lentokentältä elokuussa löytyneestä räjähteitä sisältäneestä droonista Saksa on sen sijaan syyttänyt Venäjää.

Sabotage! Großangriff auf unser Stromnetz

Berlin – Deutschland erlebt beunruhigende Angriffe auf seine kritische Infrastruktur. Innerhalb von nur drei Tagen kam es bundesweit zu mehreren Sabotageakten an Umspannwerken. Einiges spricht dafür, dass die Angriffe vom selben Täter geplant wurden. So liegen die Sabotagen nicht nur zeitlich eng beieinander, auch die Abschusskonstruktionen sollen sich ähneln, heißt es aus Sicherheitskreisen. Nach einem Bekennerschreiben gibt es eine Spur.

An executive order has officially been signed by President Donald Trump declaring a national emergency in order to secure the US bulk-power system.

The order was signed by the president in the Oval Office yesterday (August 26) which declared that Trump’s highest duty is to protect the ‘national security, foreign policy, and economy’ of the US.

The order claimed: “Certain foreign actors are increasingly creating and exploiting vulnerabilities in the United States bulk-power system, which provides the electricity that supports our national defense, vital emergency services, critical infrastructure, and economy.

The attack caused real-world operational disruption and raised concerns about the resilience of Britain’s distributed energy infrastructure and the potential for repeatable attacks.

Iran-linked hackers reportedly managed to shut down a British power plant for four days in July 2026. The story was broken by the Telegraph newspaper on August 22, 2026. That it took so long to become public knowledge immediately says two things. Firstly, it was not a major power plant since the effect would have been immediately noticed, and secondly, the authorities wished to keep news of the attack as low key as possible.

Other newspapers (for example the BBC, the Guardian and the Financial Times) have since published their own stories, largely based on the Telegraph account. There has been virtually no information coming from the expected official sources, such as the NCSC. The BBC report comments, “While the Western cyber-security world is braced for attacks either from the state [of Iran] or hackers linked to the state as a result of its conflict with the US this year, there has been little activity so far.”

Expert warns one coordinated strike could leave U.S. grid with 18-month blackout
This would be a major target for a foreign adversary
https://www.uniladtech.com/news/tech-news/us-electrical-grid-vulnerable-coordinated-strike-lengthy-blackout-079942-20260827?utm_content=tech&utm_medium=Social&utm_source=facebook#Echobox=1787845353

The potential for a coordinated attack on the U.S. electrical grid could lead to catastrophe, as one expect speculates that current infrastructure would be completely wiped out for as long as 18 months.

This wouldn’t just be your average blackout, as critical systems and anything that uses electricity would be rendered useless without emergency action or backup, leaving the world’s most powerful nation hypothetically exposed to a rather major vulnerability.

For most other nations this would take a pretty significant attack, likely over a prolonged period of time, yet one well coordinated action across nine separate key power substations could completely shut down the country.

Not only would this cause chaos on an individual level across the country with people’s lives fundamentally changed, but it would likely serve as a precursor to additional military action from one of America’s strongest foes, proving to be the preparation before the knockout blow.

One attack could wipe out the U.S. power grid
As reported by the New York Times, this significant vulnerability was identified in analysis conducted by Jon Wellinghoff, former chairman of the Federal Energy Regulatory Commission (FERC), as he had spotted a potential weak point that adversaries could exploit in an attack.

He discovered that wiping out nine critical substations across the three grid intersections in America – the Western, Eastern, and Texas Interconnections – the country would be left without power.

“We came up with some very astounding numbers,” Wellinghoff explained. “If you knock out nine total substations among those three grids, you can black out the entire United States.”

It’s not any particular substations either – which makes it far more dangerous – as Wellinghoff indicates that any nine across the ten most important within its corresponding region could be targeted, making it even more difficult to orchestrate preventative measures.

“You just have to figure out what are the top 10 critical ones in each of those interconnects. Which, to do that, it’s probably something that a bunch of 12-year-olds with the internet could do pretty easily. All you have to do is look at a map of the grid and figure out where most of the wires go into the substations — that’s a critical substation.”

How would this lead to an 18-month blackout?

This would obviously be scary enough on its own, but the aging and complex nature of high-voltage power transformers on the grid would mean that it’d take roughly 18 months for things to be restored back to normal, which is a prospect that’s hard to come back from.

Infrastructure across the United States is often custom-built, heavily backordered, and hard to replace, meaning that there’s only a certain amount of money that can be thrown at the issue before you run into potential blockades.

Combine this with the rapidly growing power demands of new technology like AI – alongside its burgeoning importance in the political sphere – and this vulnerability would leave America incredibly exposed if a sophisticated attack was carried out.

The attack caused real-world operational disruption and raised concerns about the resilience of Britain’s distributed energy infrastructure and the potential for repeatable attacks.

”Jos verkko vikaantuu, järjestelmämme näyttää X-merkin kartalla: juuri tuossa. Kuulostaa perusjutulta, mutta sitä se ei ole”, kertoo Safegridin toimitusjohtaja Paula Laine.
