Huominen on kalliin sähkön päivä. Pitkästä aikaan näin. Syyt 1) vähän tuulta meillä ja naapureilla 2) OL3 huollossa 3) OL1 päivän jonkin venttiilin korjauksessa

Me saadaan Ruotsista 3000 MW:a sähköä lähes koko päivän. Baltiaan viedään 800-1000 MW:a.

Koko lokakuun hintakisa me voitettiin aivan ylivoimaisesti.

Kävin Suomen parhaan energiapodin #Regeneranssi vieraana. Kuuntelusuositus siitä huolimatta.
”Sähkönkuluttaja saa olla hyvin rauhassa pitkään. Tulen pitkään laittamaan X:ään postauksen, että taas voitettiin sähkön hintakisa Euroopassa." -@majulepp Energiamessut ovat vain kerran vuodessa, mutta tunnelmiin pääsee takaisin podcastin parissa. open.spotify.com/episode/0lP…

Italy and Spain demand solidarity whenever their debt blows up. But they show no solidarity when Ukraine gets invaded and freeride on Germany and others to pay. I think they misunderstand the word solidarity. What they do is grifting. That's different... robinjbrooks.substack.com/p/…

Eivät pidä Muskin perustelut vettä, taaskaan.
Elon Musk claims that Ukraine allegedly violated Starlink's terms of use and used the system on combat drones. As someone who was inside the process at the Ministry of Defense, I can say with certainty that this is not true. In February of this year, whitelists were introduced. Stationary terminals could be registered by both military personnel and civilians. But for any satellite terminal to work while on the move, it had to be added to a special list and connected to the military Starshield system. Otherwise, no satellite communication terminals in Ukraine would work. In other words, using civilian Starlink for drone missions was technically impossible. All drone missions that required satellite communication could only be carried out using Starshield. We are very grateful to the United States and SpaceX for access to critically important satellite communications. Ukraine did not violate the terms of use.

Elon on poliittisesti infantiili. Omaisuus ja teknologiayhtiöiden hallinta tuo hänelle vaarallisen paljon vaikutusvaltaa.
Elon Musk's X account has devolved into a 24/7 exercise in dumbfuckery. This is what truly desperate shitposting looks like. He's losing, he knows it — and the meltdown has been spectacular.

Tuulivoima on pitänyt lokakuun sähkön hinnan Suomessa erinomaisesti kurissa. Ydinvoimaa on ollut vuosihuoltojen takia vain noin puolet täydestä tehosta markkinalla. Jos keskiarvo pysyy tuossa 3700 MW:n tasossa, niin tuuli tuottaa yli 2,7 TWh sähköä lokakuussa.

2,7 TWh olisi kautta aikain toiseksi paras tuotantokuukausi.

Harvapa olisi ennustanut, että OL3:n ja Loviisan toisen reaktorin puuttuessa Suomen sähkön hinta on aivan eri tasolla kuin naapureissa. Lokakuun sähkön hintakisassa ei voittajaa tarvitse desimaaleista etsiä.

MIND-BLOWING STATS: A record 2/3 of new cars in China are now electric, while combustion-car sales have fallen by 2/3 since they peaked in 2017 – In 2020, ~95% of sales were combustion-engine cars – By Sep 2026, they crashed to 33% – On the flip side, NEVs hit a record 67% 🧵

Muskilla on verta käsissään. Jos hänellä ei ollut hallinnon lupaa säätää Starshielidiä, niin hän lienee myös rikkonut lakia. Luulenpa, että vaalien jälkeen tätä tutkitaan kongressissa.
“But a person familiar with the situation said Musk talked to multiple senior administration officials, including with Trump, before imposing the new speed cap, which Ukrainian officials said had allowed Russian missiles to evade their defenses.” wsj.com/world/ukraine-starli…

#energiamessut Tampereella. Datakeskukset sähköistävät tunnelmaa. Vety edelleen yllättävän paljon esillä. Sääntely, liikenne, merituulivoima, ... paljon kerkesi päivässä kuunnella. Regeneranssipodissa juteltiin messujen herättämistä ajatuksista.

Pitääkö olla huolissaan datakeskuksista ja niiden vaikutuksista sähkömarkkinoiden? Pohdintaa aiheesta, olkaa hyvät! Kysyn myös, kestävätkö poliitikkojen hermot. energiauutiset.fi/blogit/oma… – at Pirkkala, Suomi

As US Secretary of the Treasury @SecScottBessent clearly has absolutely no idea what he is talking about and asks “Where is Germany?” when it comes to the supply of Patriot fire units and missiles to Ukraine, I thought this might be a good time for an educational tweet. Let's first talk about the supply of fire units and afterwards about the supply of missiles. Germany, Mr. Secretary, has in fact supplied more MIM-104 Patriot fire units to Ukraine than the US has, despite owning and operating only a fraction of what the US owns and operates. About half of Ukraine's MIM-104 Patriot fire units came from Bundeswehr stocks. A total of five fully equipped MIM-104 Patriot fire units were supplied from Bundeswehr stocks between 2023 and 2025 alongside a few extra launchers and most likely a spare radar unit. Germany began donating Patriot related equipment to Ukraine at the same time the US has and still does it until this day while the US has long stopped donating this to Ukraine. Let's now talk about missiles. Together with every fire unit, Germany also donated a missile package. Known donations included for example 100 missiles and 64 missiles. That's substantial, but of course, this only guaranteed the immediate operational readiness of said fire units, nothing else. We didn’t have our own production facilities and our stocks weren’t even remotely as well-stocked as those in the US. The US (led by Biden) actually kept those fire units alive. In February 2025, before the delivery of the last two MIM-104 Patriot fire units took place, before various donations via PURL and JUMPSTART took place and before Germany made several smaller missile deliveries from its own stocks, the German MoD confirmed to have delivered 328 Patriot missiles of various versions. By now the number of Patriot missiles already financed and delivered should exceed 500 easily. But what about what's happening now? Germany has shown multiple times since President Trump took office that it is leading in the organisation, funding and delivery of new ammunition for Ukraine's MIM-104 Patriot fire units. The German government has multiple times organized or tried to organize new deliveries for Ukraine. For example, in February 2026, Germany was in talks with multiple nations to find a total of 35 PAC-3 missiles for Ukraine. After weeks-long negotiations, 30+ were actually donated as a result of the German initiative. Germany was also — on the highest levels — in talks with Spain and Greece for the delivery of additional missiles. But of course, we are doing things beyond. A lot of things. As already mentioned, Germany is actively funding Patriot missiles from the US both via JUMPSTART and via PURL. You shouldn't forget @SecScottBessent, that we are paying you for this. As recently as June 2026, Germany spent a total of $200 million on PAC-3 missiles via JUMPSTART and another $200 million on various missiles via PURL. Total donations already exceed $1 billion. And now to the final and biggest part: In April 2026, Germany announced an enormous missile package for Ukraine. Over the following years, Germany will spend €3.2 billion to finance 600 PAC-2 GEM-T missiles for Ukraine's MIM-104 Patriot fire units — made in Germany by the way. So please don't ask what Germany is doing for Ukraine. We do more for Ukraine then anybody else, including the US. All you do now is getting paid billions for the bare minimum. PS: For full transparency it must be noted that multiple nations like Denmark, Lithuania and Norway above all have supported Germany financially in the delivery or re-procurement of MIM-104 Patriot fire units and missiles.

Jahas. Jos tämä pitää paikkaansa, niin törkeys on niin suurta, että Yhdysvaltain kansalaisten soisi puuttuvan asiaan. Ja Eurooppa voisi todella herätä Yhdysvaltain nykyhallinnon ja Muskin epäluotettavuuteen.
Latest: ​Zelenskyy tells reporters over WhatsApp that restrictions on Ukraine's Starlink systems remain. Interceptor drones can't function, logistics and operations hobbled. The maximum speed is 161 kph; "exceeding this limit causes the Starlink connection to cut out completely, resulting in the loss of the drone." He says Ukraine has done tests to determine whether SpaceX is truly facing technical issues, as has been told Kyiv by the US side, or if this is a "deliberate operation... to restrict us, cut us off, and prevent us from defending ourselves and protecting our people, both at the front and among the civilian population." He says Ukraine "sent a couple of vehicles equipped with Starlink terminals into European Union territory." "They moved at speeds exceeding 180kph, and the Starlink systems worked perfectly. We have the relevant logs and evidence to prove this." He adds: "The conclusion is clear: the restrictions are in effect within Ukraine but do not apply within the European Union. In other words, this is a planned operation."
