> A giant outage in Latvia on June ninth concentrated minds
"Giant" per what definition? It happened because of damaged isolation for 330kV line and automatics just shut it off. It also brought overflow within 110kV line affecting 160k people in capital and around it.
Communications was affected (apparantly they didnt test their energy backup systems), traffic, homes. Diesel generators were put to work where needed. Our datacenter was up and running, being backed up by other electricity lines and diesel.
Yeah, a MAJOR outage, but in LESS than 2 hours everything was restored.
Nothing to do with frequency. Why even mention it and try to associate with Russia?
- rzmnzm 6y agoSharing a land border with Russia also tends to concentrate minds
- the-dude 6y agoRussia is an enormous threat to Western civilization, haven't you heard? /s

It's the $insert_one_of: Chinese, Russian, North Korean, Iranian hackers who took down the electric grid, hacked hospitals etc.
- M2Ys4U 6y agoIt's not like Russian agents go around attacking The West, doing things like interfering in elections or launching chemical warfare in Western nations is it? Oh, wait, yes - that's exactly what they've done.
- zwww 6y agoChemical warfare?
- jurip 6y agoMeaning assassination with polonium, I guess. I dunno if it's chemical warfare but not something I expect from a reasonable government.
- M2Ys4U 6y agoThat too, but I was referring to the Novichok poisonings in 2018: https://en.wikipedia.org/wiki/Poisoning_of_Sergei_and_Yulia_Skripal https://en.wikipedia.org/wiki/Poisoning_of_Sergei_and_Yulia_...
- adav 6y agoI think this is referring to the poisonings in Salisbury in England in 2018.
- Nginx487 6y agoAh, Cold War... Probably, these two Russian agents who committed an assasination attempt (led to innocent human casualties), using chemical weapon on the soil of a NATO country, were particularly nostalgic.
- TheButlerian 6y agoYes, they are. The problem is that the civilized world cannot see the barbarians for what they really are, unite and deal with them. Best time to do it was in the 40s of XX century, Germany backed by the economies of the UK and USA would've gotten the job done in 2 years.
- Nginx487 6y agoThe world ruled by greed and cowardice. Russian regime could be taken down without any military involvement, applying solely economic measures like total oil and gas embargo. However, countries like Germany, sponsoring Nord Stream 2 and laundering money of Russian oligarchs in Deutsche Bank (really ashamed of this my CV record), keep this restored Neo-USSR safe and sound.
- probablypower 6y agoGrid operators have many ways to measure the severity of an outage. In Europe, this is commonly done using the Incident Classification Scale [0]. The term "giant" is not any official terminology, but that particular outage would be considered an "Extensive Incident" (red) due to it being in the T2 category, ON2 category, and possibly in the L2 category (maybe L1, I don't know the Latvian grid well enough). A lot of people in the industry would say that a 'red' incident is 'giant', as they tend to have high standards for reliability and security.
