Storm Hannes has caused widespread power outages in our electricity distribution area

30.12.2025 10:40am

Yesterday, we managed to restore electricity in several areas in Terjärv, Kvimo and Kovik. However, there are still households without power in the area, and repair work is ongoing. It is unlikely that electricity will be restored to everyone today, but work will continue tomorrow.

We kindly ask you to continue sending reports of trees fallen on power lines to:
📧 dc.jakobstad@herrfors.fi

The weather will become colder this evening, and our top priority is to restore electricity to homes. At this stage, we are therefore not able to clear all fallen trees, but are focusing on reconnecting as many customers as possible today. We have personnel working in all areas.

Status by area

  • The 20 kV network has been restored
  • Work is continuing in the low-voltage network

  • New lines are being built and new poles are being erected
  • Several customers will have power restored during the day, but not all
  • In the areas around Högnabba, Emas and Peckas, electricity unfortunately cannot be fully restored today due to extensive damage to the high-voltage network

We continue repair work with full staffing together with our partners and will provide further updates as the situation develops.

We thank our customers for their patience and understanding.

29.12.2025 9:30am

Storm Hannes has caused significant damage to our electricity distribution network, and substantial disruptions remain. At present, approximately 1,200 customers are without power, most of them in Terjärv, where more than 600 consumption points are without electricity. In addition, we are aware that there are numerous consumption points that do not appear on the outage map and about which we have not yet received information.

We kindly ask that reports regarding trees fallen onto power lines continue to be sent to dc.jakobstad@herrfors.fi.

Situation by Area

Terjärv

  • Several medium-voltage poles have been broken and power lines are lying on the ground
  • Some faults require the construction of entirely new lines, which is time-consuming
  • Full staffing is in place, along with contractors installing new poles
  • External clearing crews are also working along the lines
  • We are investigating reserve supply options – approximately 100 customers have been restored via reserve supply (through Korpelan Voima)

Oravais–Maxmo (approx. 360 customers without power)

  • Repair work is ongoing
  • Trees on the lines and partially broken poles

Pedersöre (approx. 120 customers)

  • In Härö along Kolpintie Road, a transformer pole has been broken
  • A new transformer station must be built in the area
  • Work is underway today

Ylivieska–Alavieska (approx. 60 customers)

  • Trees on the lines and several medium-voltage poles have been broken
  • Work is being carried out with full staffing
  • Fault repairs are ongoing today

Repair Schedule and Communication

At this time, we are unable to provide precise estimates for when power will be restored. In repair operations, permanently occupied residences are prioritized; holiday homes will be reconnected thereafter. Some customers will have their electricity restored today, while others will have to wait longer due to the extent of the damage.

We have received all fault reports. Although we have not been able to respond to each one individually, all reports have been recorded in our system. Our telephone service is currently congested, but there is no technical fault with the lines. We kindly ask customers to continue reporting faults if new damage is observed.

Yesterday, we conducted extensive drone inspections along the lines in the Fäboda–Pörkenäs and Bennäs areas, during which several faults were identified. Today, the wind is very strong (up to 18 m/s), which may limit the use of drones. Inspections will continue as weather conditions allow.

Fault detection and repair work are carried out simultaneously. Medium-voltage lines remain the top priority today, as restoring them enables electricity to be returned to the widest possible area.

Safety

Do not under any circumstances touch or approach power lines lying on the ground. They are life-threatening if energized.

We thank our customers for their patience and understanding in this exceptional situation. We will provide further updates as soon as there are changes in the situation.


28.12.2025 9pm

Storm Hannes has caused extensive damage to our electricity distribution network. We have received hundreds of reports of trees that have fallen onto power lines, lines lying on the ground, broken electricity poles, as well as damaged and non-operational transformers. At its peak, nearly 18,000 consumption points in our electricity network were without power.

All personnel within our network organization have been working since the beginning of the storm. In addition to our own staff, partner contractors are also on site. To ensure work safety, we must also make sure that our personnel get adequate rest. Without sufficient rest, efficiency decreases and the risk of accidents increases. We are working as quickly and efficiently as possible.

At present, our main focus is on restoring the high-voltage network. Once that is completed, work will begin on the low-voltage network. Unfortunately, at this stage we are unable to estimate how long the repair work in different areas will take. Restoring the entire distribution network will take several days.

We thank everyone for the reports we have received regarding fallen trees. These reports greatly assist our fault-finding efforts. We kindly ask that reports continue to be sent to dc.jakobstad@herrfors.fi or via private message on Facebook.

We will continue to inform our customers as soon as new information becomes available. We are grateful for your understanding and apologize for the situation caused by Storm Hannes. Unfortunately, the storm hit our distribution area the hardest. The situation is difficult for everyone. Repairs will take time, but together we will get through it.


28.12.2025 2am

Update regarding the storm and the damage it has caused to our electricity distribution network. We are currently facing a challenging situation, with countless trees having fallen onto power lines and caused power outages. Our entire organization is working to restore electricity distribution to all of our customers. We hope for your understanding regarding the inconvenience caused by the exceptional weather conditions.


27.12.2025 7pm

Due to strong winds, trees have fallen onto power lines, causing power outages in several parts of our electricity distribution area. As the wind remains very strong, outages are currently occurring faster than we are able to repair them. However, our staff are continuously working to fix the faults and restore electricity distribution. We will provide further updates as more information about the situation becomes available.

Thank you for your patience!
