Oslo, Norway – Nordic energy systems are facing increased scrutiny following reports of potential threats, prompting heightened vigilance from authorities across the region. Statnett, the Norwegian state-owned enterprise responsible for operating the country’s power grid, confirmed We see closely monitoring the situation and maintaining communication with relevant authorities, following reports in Swedish media.
The reports, initially surfacing in Swedish media outlet TV4 on Thursday, February 26, 2026, indicate a threat targeting energy systems throughout the Nordic countries. The Swedish Defence Radio and Security Agency (FRA) reportedly urged the sector to exercise increased caution in light of a cyberattack against the energy sector in Poland in December 2023. Statnett acknowledged awareness of the reports and stated it is taking the situation seriously.
Heightened Alert Across the Nordic Region
While the precise nature of the threat remains unclear, the reports have triggered a wave of concern across the Nordic region, known for its interconnected energy infrastructure. The interconnectedness of the Nordic power grid, managed by Statnett in Norway, Svenska Kraftnät in Sweden and Energinet in Denmark, means a disruption in one country could have cascading effects throughout the region. This makes the region particularly vulnerable to coordinated attacks.
Statnett plays a critical role in ensuring a reliable power supply in Norway, owning and operating the transmission grid and balancing electricity consumption with production. As the system operator, the company is responsible for maintaining the stability of the power system and preventing blackouts. The company’s recent investments in grid infrastructure, including the completion of a modern power line between Aurland and Sogndal in February 2025, aim to enhance the security and capacity of the electricity grid. This new line increases the capacity of the electricity grid between Central and Western Norway.
Recent Infrastructure Investments and Security Concerns
Statnett has been actively investing in upgrading its infrastructure in recent years, recognizing the growing importance of a resilient power grid. In 2025, the company increased its investments in the power grid and electricity system, although this also contributed to a negative underlying result in the first half of the year. These investments are partially driven by the increasing demand for electricity due to electrification efforts across various sectors.
Statnett is pioneering the use of new technology to reduce its carbon footprint. The company is currently constructing four new transformer stations that will be completely free of sulfur hexafluoride (SF6), a potent greenhouse gas. This initiative, announced in May 2025, marks the first time this technology is being implemented across the entire Statnett network. This demonstrates a commitment to both environmental sustainability and technological innovation.
A Changing Threat Landscape
The increased focus on grid security comes amid a broader recognition of a changing threat landscape. Statnett’s 2024 Annual and Sustainability Report highlighted the need for a more resilient power grid in the face of evolving threats. The report emphasized that a robust power grid is crucial for Norway’s national emergency preparedness. Over the next decade, Statnett plans to more than double its investments in grid infrastructure to address these challenges.
The attack on the Polish energy sector in December 2023, cited by the Swedish FRA, serves as a stark reminder of the vulnerability of critical infrastructure to cyberattacks. While details of the Polish incident remain limited, it prompted a reassessment of security protocols across the Nordic region. The FRA’s call for increased vigilance underscores the growing concern about potential disruptions to energy supplies.
Gassco Monitoring Gas Infrastructure
While the initial reports focused on the broader energy systems, concerns also extended to natural gas infrastructure. However, Gassco, the Norwegian state-owned company responsible for gas transport, stated that, as of Thursday, February 26, 2026, there was “no concrete threat” to Norwegian gas infrastructure. This statement, provided to NRK, indicates a focused monitoring effort but does not suggest an immediate risk to gas supplies.
The situation remains fluid, and authorities across the Nordic region are continuing to monitor developments closely. Statnett’s commitment to maintaining communication with relevant authorities and its ongoing investments in grid security are crucial steps in mitigating potential risks and ensuring a reliable power supply for Norway and the wider Nordic region.
