Statnett: Five times more lightning than normal – Dagbladet.no

This year, Statnett has recorded nearly 550,000 lightning over Norway. That’s five times more than normal during a whole year.

It flashed most Monday 4 August. Then there were registered 91,785 lightning over Norway. More than half of these were from cloud to ground, writes the mission funded news agency Newswire.

There has never been registered as many lightning that year. The normal is around 110 000 lightning annually.

– Avoids power failure

The registration is a collaboration between Statnett and SINTEF and provides the basis for lynkartene. They show exactly where lightning has struck and prepared on the basis of information on lightning activity captured by sensors.

– Lynvarsling can do that we avoid power failure, or power failure becomes shorter. We will have time to add spare capacity in the pipeline and can put crews on alert to scramble, says director Olav Stokke Statnett.

Today, it consists Norwegian lynsystemet of 16 sensors, 14 of which are located in Norway, one in Shetland and one in Denmark. In addition, cooperation on data exchange with other European countries.

A total of 153 lynsensorer in operation in Europe today, from the Canary Islands in the south to Vardo in the north.

a lightning the crowd

Over the past few years, SINTEF replaced the old sensors and autumn set a new central unit in operation.

– Already now we see that the new equipment detects multiple cloud-to-ground lightning than the old one, and that the accuracy of the records are better, says researcher Frank Dahlslett SINTEF Energy.

Dahlslett says interest in The registration has been great this summer and that they will consider various solutions to make a lightning available for most Norwegians.
