Yesterday's thunderstorm caused power supply interruptions to some 3,500 customers in the distribution area of Oulun Energia Sähköverkko Oy. Power was restored to them during the night.

We added staff to the outage repair team, but the high number of breakdown calls and enquiries has caused delays in service.

A new forecast predicts a thunderstorm for Tuesday, 22 June, from the afternoon to noon the following day. This will inevitably lead to new faults, and we would like to remind you that if you see a fallen tree on a power line, or a broken cable, you should not go near it, and the safety distance is 20 metres.

If there are strange problems with electricity, such as the lights are flashing, brightening, and dimming, then it may be a case of a dangerous open neutral. In this event, the power must be cut off at the main switch without touching the metal parts, and you must wait until the fault is rectified by our contractor. This defect usually occurs during a storm when a tree breaks a cable that acts as an overhead support wire, and grounding and neutral wire.

We have increased the number of fault repair personnel and loggers in case of future thunderstorms. We will patrol the overhead power line by helicopter as soon as the weather permits, and the helicopter may cause noise.

We apologise for any inconvenience caused by the interruptions.
