This is a way to increase vigilance in a tricky time, Ola Billger, head of communications at FRA, told TT.
According to information provided to TV4 Nyheterna, Swedish police have gone on alert in an international operation and are guarding critical facilities. Several authorities and police units throughout the Nordic region have also reportedly gone on alert. The Swedish Civil Defence Agency (MCF) and the Swedish Energy Agency both state that they are aware of the information.
FRA says it has urged actors in Sweden's energy sector to be more vigilant recently.
"We did that last Friday," says Ola Billger.
Be vigilant
The background to the call, according to FRA, is the extensive cyber attack that was targeted at the Polish energy sector at the end of December.
The attack was stopped, but the Polish government considered the attack "serious" and pointed to groups with links to Russia as responsible.
"In this case, we think there is reason to be extra vigilant in the energy sector, because we have seen how other countries' energy sectors have been subjected to destructive cyber attacks."
"No specific threat"
Is there any specific threat directed at Sweden right now?
"No," says Ola Billger.
"This is a way to raise the level of alert in Sweden, but it is not the same as saying that there is an attack going on right now."
Neither Svenska kraftnät nor the Swedish Energy Agency are aware of "any specific threat or incident".
"There has been a threat to the energy sector for a long time, it is nothing new. That is why we work systematically on our security protection every day, so that Sweden has a robust and secure electricity supply," says Thomas Pålsson, Director General of Svenska kraftnät, in a press release.
In its annual report, Must has warned of an increased risk of Russian saboteurs, especially linked to Sweden's military support for Ukraine.
