A malfunction caused a shutdown of a nuclear power reactor at one of South Korea's atomic power plants, authorities said.

Operators at the Younggwang Nuclear Power Plant in South Cholla Province said operations of Unit No. 1 were suspended after a malfunction was detected.

"There was no radiation leakage, and once experts determine the exact cause of the malfunction, operations will begin again," said a spokesman for the plant, located 322 kilometres south of Seoul. Minor malfunctions that could lead to a shutdown are not reported to the International Atomic Energy Agency.

The generator is one of six units in the power plant. It went into commercial operation in August 1986 and has generates 950 megawatt of electricity.

In addition to the Younggwang plant, South Korea operates 20 nuclear reactors throughout the country that fuel 40 per cent of the country's electricity needs.

A New Era for Churchill Falls: Newfoundland and Labrador Secures Billions in Landmark Deal with Quebec

Churchill Falls NL-Quebec Agreement boosts hydropower revenues, revises power purchase pricing, expands transmission lines, and integrates Indigenous rights, enabling renewable energy growth, domestic supply, exports, and interprovincial collaboration on infrastructure and utility modernization.

 

Key Points

A renegotiated hydropower deal reallocating power and advancing projects with Indigenous benefits in NL and Quebec.

✅ Raises Hydro-Quebec price for Churchill Falls electricity

✅ Increases NL power share for domestic use and exports

✅ Commits joint projects and Indigenous participation safeguards

 

St. John's, Newfoundland and Labrador - In a historic development, Newfoundland and Labrador (NL) and Quebec have reached a tentative agreement over the controversial Churchill Falls hydroelectric project, amid Quebec's electricity ambitions and longstanding regional sensitivities, potentially unlocking hundreds of billions of dollars for the Atlantic province. The deal, announced jointly by Premier Andrew Furey and Quebec Premier François Legault, aims to rectify the decades-long imbalance in the original 1969 contract, which saw NL receive significantly less revenue than Quebec for the province's vast hydropower resources.

The core of the new agreement involves a substantial increase in the price that Hydro-Québec pays for electricity generated at Churchill Falls. This price hike, retroactive to January 1, 2025, is expected to generate billions in additional revenue for NL over the next several decades. The deal also includes provisions for:

  • Increased power allocation for NL: The province will gain a larger share of the electricity generated at Churchill Falls, allowing for increased domestic consumption and potential export opportunities through the sale and trade of power across regional markets.
  • Joint infrastructure development: Both provinces will collaborate on new energy projects, in line with Hydro-Québec's $185-billion plan to reduce fossil fuel reliance, including potential expansions to the Churchill Falls generating station and the development of new transmission lines.
  • Indigenous involvement: The agreement acknowledges the importance of Indigenous rights and seeks to ensure that Indigenous communities in both provinces benefit from the project.

This landmark deal represents a significant victory for NL, which has long argued that the original 1969 contract was grossly unfair. The province has been seeking to renegotiate the terms of the agreement for decades, citing the low price paid for electricity and the significant economic benefits that have accrued to Quebec.

Key Implications:

  • Economic Transformation: The influx of revenue from the new Churchill Falls agreement has the potential to significantly transform the economy of NL, though the legacy of Muskrat Falls costs tempers expectations before plans are finalized. The province can invest in critical infrastructure projects, such as healthcare, education, and transportation, as well as support economic diversification initiatives.
  • Energy Independence: The increased access to electricity will enhance NL's energy security and reduce its reliance on fossil fuels. This shift towards renewable energy aligns with the province's climate change goals, and in the context of Quebec's no-nuclear stance could attract new investment in sustainable industries.
  • Interprovincial Relations: The successful negotiation of this complex agreement demonstrates the potential for constructive collaboration between provinces on major infrastructure projects, as seen in recent NB Power-Hydro-Québec agreements to import more electricity. It sets a precedent for future interprovincial partnerships on issues of shared interest.

Challenges and Considerations:

  • Implementation: The successful implementation of the agreement will require careful planning and coordination between the two provinces.
  • Environmental Impact: The expansion of hydroelectric generation at Churchill Falls must be carefully assessed for its potential environmental impacts, including the effects on local ecosystems and Indigenous communities.
  • Public Consultation: It is crucial that the governments of NL and Quebec engage in meaningful public consultation throughout the implementation process to ensure that the benefits of the agreement are shared equitably across both provinces.

The Churchill Falls agreement marks a turning point in the history of energy development in Canada. It demonstrates the potential for provinces to work together to achieve mutually beneficial outcomes, even as Nova Scotia shifts toward wind and solar after stepping back from the Atlantic Loop, while also addressing historical inequities and ensuring a more equitable distribution of the benefits of natural resources.

USA: 3 Ways Fossil Energy Ensures U.S. Energy Security

DOE Office of Fossil Energy safeguards energy security via the Strategic Petroleum Reserve, domestic critical minerals from coal byproducts, and carbon capture to curb CO2, strengthening resiliency amid shocks and supporting U.S. manufacturing and defense.

 

Key Points

A DOE program advancing energy security through SPR stewardship, critical minerals R&D, and carbon capture.

✅ Manages the Strategic Petroleum Reserve for emergency crude supply

✅ Develops domestic critical minerals from coal and mining byproducts

✅ Deploys carbon capture, utilization, and storage to cut CO2

 

The global economy has just experienced a period of unique transformation because of COVID-19. The fact that remains constant in this new economic landscape is that our society relies on energy; it’s an integral part of our day-to-day lives, even as U.S. energy use has evolved over time. According to the U.S. Energy Information Administration, approximately 80 percent of energy consumption in the United States comes from fossil fuels, so having access to a secure and reliable supply of those energy resources is more important than ever for national energy security considerations today. Below are three examples that highlight how our work at the U.S. Department of Energy’s Office of Fossil Energy (FE) helps ensure the Nation’s energy security and resiliency.

(1) Open crude oil reserves to respond to crises

FE has overall program responsibility for carrying out the mission of the Strategic Petroleum Reserve (SPR), the world’s largest supply of emergency crude oil. These federally-owned stocks are stored in massive underground salt caverns along the coastline of the Gulf of Mexico. The SPR is a powerful tool U.S. leaders use to respond to a wide range of crises, including energy crisis impacts on electricity and fuels, involving crude oil disruption or demand loss.  When the COVID-19 pandemic hit, the oil markets crashed and crude oil demand dropped drastically across the world. U.S. oil producers turned to the SPR to store their oil while broader energy dominance constraints were becoming evident in practice. This helped alleviate the pressure on producers to shut in oil production and proved to be a critical asset for American energy and national security.

(2) Use the Nation’s abundant coal reserves to produce valuable materials

Critical materials, including rare earth elements, are a group of chemical elements and materials with unique properties that support manufacturing of most modern technologies. They are essential components for critical defense and homeland security applications, green energy technologies, hybrid and electric vehicles, and high-value electronics. While these materials are not rare, they are hard to separate and expensive to extract. The United States relies heavily on imports from China. To reduce U.S. dependence on foreign sources, FE has a research and development program aimed at producing a domestic supply of critical materials from the Nation’s abundant coal resources and associated byproducts from legacy and current mining operations. Many of the technologies being developed can also be used to separate critical minerals from other mining materials and byproducts. Tapping into these resources has the potential to create new industries and revitalize coal communities and the workforce in coal-producing regions.

(3) Decrease carbon emissions for a cleaner energy future

FE is committed to balancing the Nation’s energy use with the need to protect the environment, and has a comprehensive portfolio of technological solutions that help keep carbon dioxide (CO2) emissions out of the atmosphere. For example, amid high natural gas prices that reinforce the case for clean electricity, the Department has been investing in carbon capture, utilization, and storage technologies for over a decade. These technologies capture CO2 emissions from various sources, including coal-fired power plants and manufacturing plants, before they enter the atmosphere. Several of these cutting-edge technologies have been deployed at major demonstration sites, supported by clean energy funding that aims to benefit millions. Three of these projects—Petra Nova, Archer Daniels Midland, and Air Products & Chemicals—have captured and injected over 10.8 million metric tons of CO2. The success of these projects is paving the way toward a cleaner and more sustainable American energy future.

Russian Missiles and Drones Target Kyiv's Power Grid in Five-Hour Assault

Assault on Kyiv's Power Grid intensifies as missiles and drones strike critical energy infrastructure. Ukraine's air defenses intercept threats, yet blackouts, heating risks, and civilian systems damage mount amid escalating winter conditions.

 

Key Points

Missile and drone strikes on Kyiv's power grid to cripple infrastructure, cause blackouts, and pressure civilians.

✅ Targets power plants, substations, and transmission lines

✅ Air defenses intercept many missiles and drones

✅ Blackouts jeopardize heating, safety, and communications

 

In a troubling escalation of hostilities, Russian forces launched a relentless five-hour assault on Kyiv, employing missiles and drones to target critical infrastructure, particularly Ukraine's power grid. This attack not only highlights the ongoing conflict between Russia and Ukraine but also underscores the vulnerability of essential services, as seen in power outages in western Ukraine in recent weeks, in the face of military aggression.

The Nature of the Attack

The assault began early in the morning and continued for several hours, with air raid sirens ringing out across the capital as residents were urged to seek shelter. Eyewitnesses reported a barrage of missile strikes, along with the ominous whir of drones overhead. The Ukrainian military responded with its air defense systems, successfully intercepting a number of the incoming threats, but several strikes still managed to penetrate the defenses.

One of the most alarming aspects of this attack was its focus on Ukraine's energy infrastructure. Critical power facilities were hit, resulting in significant disruptions to electricity supply across Kyiv and surrounding regions. The attacks not only caused immediate outages but also threatened to complicate efforts to keep the lights on in the aftermath.

Impacts on Civilians and Infrastructure

The consequences of the missile and drone strikes were felt immediately by residents. Many found themselves without power, leading to disruptions in heating, lighting, and communications. With winter approaching, the implications of such outages become even more serious, as keeping the lights on this winter becomes harder while temperatures drop and the demand for heating increases.

Emergency services were quickly mobilized to assess the damage and begin repairs, but the scale of the attack posed significant challenges. In addition to the direct damage to power facilities, the strikes created a climate of fear and uncertainty among civilians, even as many explore new energy solutions to endure blackouts.

Strategic Objectives Behind the Assault

Military analysts suggest that targeting Ukraine's energy infrastructure is a calculated strategy by Russian forces. By crippling the power grid, the intention may be to sow chaos and undermine public morale, forcing the government to divert resources to emergency responses rather than frontline defenses. This tactic has been employed previously, with significant ramifications for civilian life and national stability.

Moreover, as winter approaches, the vulnerability of Ukraine’s energy systems becomes even more pronounced, with analysts warning that winter looms over the battlefront for civilians and troops alike. With many civilians relying on electric heating and other essential services, an attack on the power grid can have devastating effects on public health and safety. The psychological impact of such assaults can also contribute to a sense of hopelessness among the population, potentially influencing public sentiment regarding the war.

International Response and Solidarity

The international community has responded with concern to the recent escalation in attacks. Ukrainian officials have called for increased military support and defensive measures to protect critical infrastructure from future assaults, amid policy shifts such as the U.S. ending support for grid restoration that complicate planning. Many countries have expressed solidarity with Ukraine, reiterating their commitment to support the nation as it navigates the complexities of this ongoing conflict.

In addition to military assistance, humanitarian aid is also critical, and instances of solidarity such as Ukraine helping Spain amid blackouts demonstrate shared resilience. As the situation continues to evolve, many organizations are working to provide relief to those affected by the attacks, offering resources such as food, shelter, and medical assistance. The focus remains not only on immediate recovery efforts but also on long-term strategies to bolster Ukraine’s resilience against future attacks.

Tesla reduces Solar + home battery pricing following California blackouts

Tesla Solar and Powerwall Discount offers a ~10% installation price cut amid PG&E blackouts, helping California homeowners with solar panels, battery storage, and backup power, while supporting renewable energy and resilient Supercharger infrastructure.

 

Key Points

A ~10% installation discount on Tesla solar panels and Powerwall batteries to boost backup power during PG&E blackouts.

✅ ~10% off installation for solar plus Powerwall

✅ Helps during PG&E shutoffs and wildfire mitigation

✅ Supports resilience, backup power, and EV charging

 

Pacific Gas & Electric’s (PG&E) shutoff of electric supply to residents in California’s Bay Area has caught the attention of Tesla and SpaceX CEO Elon Musk, who, while highlighting a huge future for Tesla Energy in coming years, has announced that he would be offering a price reduction of approximately 10% for a solar panel and Tesla Powerwall battery installation. The discount will be available to anyone interested in powering their homes with solar energy, not just the 800,000 affected homes in the Bay Area.

After initially tweeting a link to Tesla’s Solar page on Tesla.com, Musk added that he would be offering a “~10% price reduction” in installation price for solar panels and Powerwall batteries for anyone, as California explores EVs for grid stability during emergencies, including those who have lost power in response to PG&E’s power shutoff. The blackout induced by the California-based power company is a part of an effort to reduce the possibility of wildfires. PG&E lines were the cause of multiple fires in the past, so the company is taking every necessary precaution to reduce the probability of its lines causing another fire in the future.

Tesla Solar recently offered a subscription program that would allow homeowners to lease panels for a fraction of the cost. The service is available to both residential and commercial customers, and costs as little as $45 a month in some states, particularly appealing in California where EV sales top 20% recently. The option to lease solar panels carries no long-term contracts that would tie down customers to a lengthy commitment.

Wildfires have always been an issue in California. Currently, fires are ripping through Los Angeles county, presumably caused by the winds of the Autumn season. The effort to reduce the environmental impact of forest fires in the state has been increasingly more prevalent over the years. But 2019 is a different story, underscoring that California may need a much bigger grid to support electrification, considering the previous year was noted as the deadliest wildfire season in California’s history. Over 8,500 fires destroyed over 1.89 million acres of land burned due to fires, causing the California Department of Forestry and Fire Protection to spend $432 million through the end of August 2018, according to the Associated Press.

In reaction to the news of the power shutoffs, Tesla added words of advice to vehicle affected owners on its app. The company posted a message encouraging drivers to keep their vehicles charged to 100% and highlighted that EVs can power homes for up to three days during outages, in order to prevent interruptions in driving. Those who are driving ICE vehicles are feeling the effects of the blackout too, as gas stations in California’s affected region have begun to shut down. Musk also tweeted that he would be installing Tesla Powerpacks at all Supercharger stations in the affected region, a move that can help ease strain on state power grids during outages, in order to allow owners to charge their vehicles.

In addition to the efforts that Tesla has already put into place, Musk plans to transition all Supercharger stations to solar power as soon as possible. But the sunny climate of California offers residents a great opportunity to move from gas and electric, even as some warn of a looming green car wreck in the state, to a more eco-friendly, sun-powered option. Tesla solar will completely eliminate power blackouts that are used to control wildfires in California.

Hydro-Quebec adopts a corporate structure designed to optimize the energy transition

Hydro-Québec Unified Corporate Structure advances the energy transition through integrated planning, strategy, infrastructure delivery, and customer operations, aligning generation, transmission, and distribution while ensuring non-discriminatory grid access and agile governance across assets and behind-the-meter technologies.

 

Key Points

A cross-functional model aligning strategy, planning, and operations to accelerate Quebec's low-carbon transition.

✅ Four groups: strategy, planning, infrastructure, operations.

✅ Ensures non-discriminatory transmission access compliance.

✅ No staff reductions; staged implementation from Feb 28.

 

As Hydro-Que9bec prepares to play a key role in the transition to a low-carbon economy, the complexity of the work to be done in the coming decade requires that it develop a global vision of its operations and assets, from the drop of water entering its turbines to the behind-the-meter technologies marketed by its subsidiary Hilo. This has prompted the company to implement a new corporate structure that will maximize cooperation and agility, including employee-led pandemic support that builds community trust, making it possible to bring about the energy transition efficiently with a view to supporting the realization of Quebecers’ collective aspirations.

Toward a single, unified Hydro

Hydro-Québec’s core mission revolves around four major functions that make up the company’s value chain, alongside policy choices like peak-rate relief during emergencies. These functions consist of:

  1. Developing corporate strategies based on current and future challenges and business opportunities
  2. Planning energy needs and effectively allocating financial capital, factoring in pandemic-related revenue impacts on demand and investment timing
  3. Designing and building the energy system’s multiple components
  4. Operating assets in an integrated fashion and providing the best customer experience by addressing customer choice and flexibility expectations across segments.

Accordingly, Hydro-Québec will henceforth comprise four groups respectively in charge of strategy and development; integrated energy needs planning; infrastructure and the energy system; and operations and customer experience, including billing accuracy concerns that can influence satisfaction. To enable the company to carry out its mission, these groups will be able to count on the support of other groups responsible for corporate functions.

Across Canada, leadership changes at other utilities highlight the need to rebuild ties with governments and investors, as seen with Hydro One's new CEO in Ontario.

“For over 20 years, Hydro-Québec has been operating in a vertical structure based on its main activities, namely power generation, transmission and distribution. This approach must now give way to one that provides a cross-functional perspective allowing us to take informed decisions in light of all our needs, as well as those of our customers and the society we have the privilege to serve,” explained Hydro-Québec’s President and Chief Executive Officer, Sophie Brochu.

In terms of gender parity, the management team continues to include several men and women, thus ensuring a diversity of viewpoints.

Hydro-Québec’s new structure complies with the regulatory requirements of the North American power markets, in particular with regard to the need to provide third parties with non-discriminatory access to the company’s transmission system. The frameworks in place ensure that certain functions remain separate and help coordinate responses to operational events such as urban distribution outages that challenge continuity of service.

These changes, which will be implemented gradually as of Monday, February 28, do not aim to achieve any staff reductions.
