LT dabar skirtumas tarp gamybos ir vartojimo 1240 MW, Kruonis pumpuoja 440 MW, eksportas turėtų būti 800 MW.
Pagal litgrid eskportuojama visomis jugntimis, į Švediją rodo 435 MW.
Švedija dabar eksportuoja elektrą penkioms valstybėms ir importuoja tik iš Lietuvos

Prieš 20min eksportas buvo pašokęs iki 885 MW, tik šįkart Kruonis ne pumpavo o generavo.
Pelninga diena Lietuvos atsinaujinančiai energetikai, visoje Europoje šiandien vėjuota tik Lietuvoje

Global Electricity Review 2025 https://ember-energy.org/latest-insi...y-review-2025/

Record renewables growth led by solar helped push clean power past 40% of global electricity in 2024, but heatwave-related demand spikes led to a small increase in fossil generation.
Clean power surpasses 40% of global electricity generation
A record surge in renewables spearheaded by solar power, combined with increased nuclear output, pushed clean electricity’s share to 40.9% of global electricity in 2024, up from 39.4% in 2023. 2024 was the first year that low-carbon sources delivered more than 40% of global electricity since the 1940s, when the global electricity system was 50 times smaller than it is today.
The global share of wind (8.1%) and solar (6.9%) is rapidly increasing, together exceeding hydropower for the first time in 2024. Hydro remained the largest source of clean electricity, providing 14.3% of global electricity generation in 2024, followed by nuclear at 9.0%. Despite remaining the two largest sources of low-carbon electricity, hydro and nuclear are not increasing their share – with nuclear’s share falling to a 45-year low in 2024 – as generation has been growing more slowly than electricity demand.
Other renewables, such as bioenergy and geothermal power, contributed 2.6% of global electricity in 2024.
80 countries generated more than 50% of their electricity from clean sources in 2024, including 47 countries that reached more than 75%.
As the global share of clean sources rose, the share of fossil fuels in the electricity mix consequently fell from 60.6% in 2023 to 59.1% in 2024, dropping below 60% for the first time since the 1940s. Coal power provided 34.4% of global electricity in 2024 and gas 22%, with other fossil fuels contributing 2.8%.
Global solar power is doubling every three years
Heatwaves drive a small increase in fossil use
Hotter temperatures the key driver of fossil power and emissions increases in 2024

Estiją ir Suomiją jungiantį kabelį „Estlink 2“ planuojama suremontuoti iki liepos 15-osios https://www.vz.lt

Estiją ir Suomiją jungiančio elektros kabelio „Estlink 2“ remonto darbai prasidės gegužę, o pagal dabartinį planą tikimasi, kad jungtis bus atkurta iki liepos 15-osios, pranešė pareigūnai.
Pažeista atkarpa remonto metu bus pakeista nauju povandeniniu kabeliu, kuris bus nutiestas beveik kilometro ilgio jūros dugno ruože. Projektui įgyvendinti bus naudojamas anksčiau pagamintas ir pristatytas rezervinis kabelis ir jungiamosios detalės. Dėl didelės darbų apimties reikalingas kruopštus planavimas ir specializuoti remonto laivai. Bendradarbiaujant su kabelių gamintoju „Nexans“ visą žiemą buvo rengiamasi remonto darbams.
Apskaičiuota, kad visos „Estlink 2“ remonto išlaidos sieks 50–60 mln. Eur, kurias lygiomis dalimis pasidalys sistemos operatoriai „Elering“ ir „Fingrid“. Išlaidas „Elering“ padengs iš lėšų, kurios skirtos tarpvalstybiniams elektros pajėgumams išlaikyti ir plėsti. Vasario–balandžio mėnesiais buvo rengiamasi remontuoti pažeistą povandeninio kabelio atkarpą. Šio etapo metu pažeista atkarpa buvo iškelta iš jūros ir pašalinta. Likęs povandeninis kabelis buvo kruopščiai išbandytas, kad būtų užtikrintas jo vientisumas.

Small Nuclear Reactors: A Path to Liberation From Russia https://cepa.org/article/small-nucle...n-from-russia/
Small Modular Reactor technology offers the EU a path to energy sovereignty, neutralizing Russia’s influence and hardening critical infrastructure against threats

Oil, or more broadly, energy, is the blood of the global economy. In 2023, European Union (EU) energy import dependency was a staggering 58%. Recent events in the Middle East, which caused oil prices to spike by more than 15% in a matter of days, once again demonstrated the risks from reliance on importing energy.
Given the current global instability and growing threats to freedom of navigation, such as the Houthi attacks in the Red Sea, and Iranian threats to close the Strait of Hormuz, both of which are critical maritime paths for oil and gas to Europe, it’s obvious that the EU should aim to domesticate its energy production.
One option is to build small modular reactors (SMRs), which are essentially compact versions of nuclear power plants fit for industrial, urban, military, and other applications. They produce up to a third of the energy of a traditional, large reactor.
SMRs’ main advantages are that, due to their size, they can be transported either as whole units or in modules and later assembled at the final destination, thereby reducing the cost of installation from which conventional reactors suffer. Another advantage is that existing designs are based on passive systems to ensure their safety, thereby minimizing the chances of radioactive leaks.
Until relatively recently, nuclear energy was in the doldrums for a host of reasons including safety fears after the 2011 Fukushima incident, lobbying from fossil fuel companies and opposition from the green political movement. However, the nuclear renaissance is now underway, with Trump’s goal of quadrupling nuclear energy output by 2050, the World Bank’s decision to lift the ban on nuclear power projects, investments from states including the United Kingdom, France, the Czech Republic, and, importantly, the rise of SMR start-ups.
There are now a host of companies pushing ahead with SMRs, including TerraPower backed by Bill Gates, along with designs from Westinghouse and Rolls Royce, which in June secured £2.5bn ($3.4bn) in UK government aid to build three SMRs, as well as Chinese and Russian contenders.
Importantly, there are two risks associated with the SMRs. Firstly, it will take several more years for the reactors to be built. Secondly, while their installation costs are expected to be a fraction of those for conventional reactors, SMRs will still require significant upfront capital investment and rely on economies of scale to become commercially viable.

Nevertheless, SMRs could play a very significant role in ensuring EU energy self-sufficiency and protected from massive blackouts caused by technical failures, or cyber-attacks, and energy export bans by Russia.
Throughout the 2000s, Russia weaponized its hydrocarbons in dealing with European countries. Later, it used their reliance as leverage to force these states to do business as usual despite its imperialist foreign policy, inter alia in Georgia, Ukraine, and Syria.
The full-scale invasion of Ukraine brought a change, with the EU significantly decreasing imports of Russian energy, yet it still continues to either directly or indirectly buy Russian oil and gas, thereby fueling the Kremlin’s efforts to continue its expansionist war against Ukraine.
If the EU deploys multiple SMRs across its members, it will result in both a reduction of Russian geopolitical leverage and a decrease in global hydrocarbon prices.
The spread of SMRs could also cut the ground from beneath pro-Russian EU states like Hungary and Slovakia, which argue the bloc should be open to “cheap” energy. Importantly, if the EU moves away from the use of oil and gas, it will decrease global demand, thereby dragging prices down. That would severely harm Russia as energy exports account for approximately 30% of its federal budget.
Another major benefit of SMRs is to decentralize the grid. Dangers of relying on centralized grid infrastructure were well demonstrated by the blackout across Spain and Portugal in April. While it was concluded that this outage wasn’t a result of a conventional or cyber-attack, back in 2021, Colonial Pipeline in the US was successfully hacked by what was reportedly a Russia-based group.
SMRs spread the risk. They can be installed at factories, airports, ports, and other sites. As a result, hackers will need to simultaneously attack hundreds of decentralized targets in order to undermine European energy security. In the same way, if Russia decides to bomb energy infrastructure, it won’t inflict the same level of damage as did in Ukraine since grid is well decentralized.
If Europe is serious about increasing its ability to defend itself, it needs to prioritize SMRs. This is not only a matter of energy, but of strategic security. Since it’s estimated that Russia may be ready to attack Europe by 2030, time is of the essence.
