From Elering signs deal with Finnish company to protect Baltic Sea HVDC cables

How could Elering's new surveillance system affect Fingrid's infrastructure security?

Possible What happens if… A possibility worth considering, not a forecast.

Elering's new surveillance system may raise regional grid security standards Elering, the Estonian TSO, has signed an agreement with Finnish defense technology provider Image Soft to deploy its 3rd Generation UNWAS™ system. This system is designed to protect critical underwater high-voltage direct current (HVDC) interconnect cables in the Baltic Sea against threats like sabotage and anchor dragging. By deploying UNWAS™, Elering sets a new standard for modern energy grid defense in the region. As Fingrid operates critical infrastructure within the same high-risk maritime environment, this regional adoption of advanced passive acoustic surveillance technology could influence how Fingrid approaches the protection and resilience of its own subsea assets.

The facts so far

As reported. Each one links to where it comes from.

  • Elering is deploying Image Soft's 3rd Generation UNWAS™ system to protect critical underwater HVDC interconnect cables in the Baltic Sea.manilatimes.net
  • The UNWAS™ system provides real-time coverage across hundreds of square kilometers of sea area.manilatimes.net
  • The system uses ultra-sensitive, passive acoustic hydrophone-based sensors to detect threats like sabotage and anchor dragging.manilatimes.net

Why it matters

The integrity of subsea electricity interconnections is vital to the security of supply in the region. For TSOs like Fingrid, maintaining the resilience of these critical underwater assets against maritime threats is a core operational and strategic concern. The adoption of advanced, passive surveillance technology by a regional peer signals a growing trend toward proactive defense of energy infrastructure in the Baltic Sea.

Both Estonia and Finland are key players in the Baltic energy market, and their TSOs share the responsibility of ensuring regional energy security. This cooperation between Elering and Image Soft highlights the increasing focus on mitigating emerging threats in high-risk maritime environments, a challenge faced by all major grid operators in the area.

What we don't know yet

  • Will other TSOs in the Baltic region adopt similar advanced surveillance technologies?
  • What specific operational changes or investments might Fingrid make in response to this regional trend?

What would change this answer

Other Baltic TSOs announce similar contracts for underwater surveillance systemsThis would confirm a rapid regional shift toward advanced CUI protection, making the effect on Fingrid stronger and more immediate.
The frequency of reported maritime threats to subsea cables increases significantlyThis would validate the need for such advanced systems, making the shift toward enhanced security for Fingrid more urgent and necessary.
