NRC Special Inspection at River Bend reviews failures of portable emergency diesel generators, nuclear safety measures, and Entergy Operations actions after Fukushima; off-site power loss readiness, remote COVID-19 oversight, and corrective action plans are assessed.

Key Points

An NRC review of generator test failures at River Bend, assessing nuclear safety, root causes, and corrective actions.

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

✅ Remote COVID-19 oversight; public report expected within 45 days

The Nuclear Regulatory Commission has begun a special inspection at the River Bend nuclear power plant, part of broader oversight that includes the Turkey Point renewal application, to review circumstances related to the failure of five portable emergency diesel generators during testing. The plant, operated by Entergy Operations, is located in St. Francisville, La., as nations like France outage risks continue to highlight broader reliability concerns.

The generators are used to supply power to plant systems in the event of a prolonged loss of off-site electrical power coupled with a failure of the permanently installed emergency generators, a concern underscored by incidents such as the SC nuclear plant leak that shut down production for weeks. These portable generators were acquired as part of the facility's safety enhancements mandated by the NRC following the 2011 accident at the Fukushima Dai-ichi facility in Japan, and amid constraints like France limiting output from warm rivers, the emphasis on resilience remains.

The three-member NRC team will develop a chronology of the test failures and evaluate the licensee's causal analyses and the adequacy of corrective actions, informed by lessons from cases like Davis-Besse closure stakes that underscore risk management.

Due to the COVID-19 pandemic, they will complete most of their work remotely, while other regions address constraints such as high river temperatures limiting output for nuclear stations. An inspection report documenting the team's findings, released as global nuclear project milestones continue across the sector, will be publicly available within 45 days of the end of the inspection.

Alberta wind power surpasses coal as AESO reports record renewable energy feeding the grid, with natural gas conversions, solar growth, energy storage, and decarbonization momentum lowering carbon intensity across Alberta's electricity system.

Key Points

AESO data shows wind surpassing coal in Alberta, driven by coal retirements, gas conversions, and growing renewables.

✅ AESO reports wind output above coal several times this week

✅ Coal units retire or convert to natural gas, boosting renewables

✅ Carbon intensity falls; storage and solar improve grid reliability

Marking a significant shift in Alberta energy history, wind generation trends provided more power to the province's energy grid than coal several times this week.

According to data from the Alberta Energy System Operator (AESO) released this week, wind generation units contributed more energy to the grid than coal at times for several days. On Friday afternoon, wind farms contributed more than 1,700 megawatts of power to the grid, compared to around 1,260 megawatts from coal stations.

"The grid is going through a period of transformative change when we look at the generation fleet, specifically as it relates to the coal assets in the province," Mike Deising, AESO spokesperson, told CTV News in an interview.

The shift in electricity generation comes as more coal plants come offline in Alberta, or transition to cleaner energy through natural gas generation, including the last of TransAlta's units at the Keephills Plant west of Edmonton.

Only three coal generation stations remain online in the province, at the Genesee plant southwest of Edmonton, as the coal phase-out timeline advances. Less available coal power, means renewable energy like wind and solar make up a greater portion of the grid.

EVOLUTION OF THE GRID
"Our grid is changing, and it's evolving," Deising said, adding that more units have converted to natural gas and companies are making significant investments into solar and wind energy.

For energy analyst Kevin Birn with IHS Markit, that trend is only going to continue.

"What we've seen for the last 24 to 36 months is a dramatic acceleration in ambition, policy, and projects globally around cleaner forms of energy or lower carbon forms of energy," Birn said.

Birn, who is also chief analyst of Canadian Oil Markets, added that not only has the public appetite for cleaner energy helped fuel the shift, but technological advancements have made renewables like wind and solar more cost-efficient.

"Alberta was traditionally heavily coal-reliant," he said. "(Now) western Canada has quite a diverse energy base."

LESS CARBON-INTENSIVE
According to Birn, the shift in energy production marks a significant reduction in carbon emissions as Alberta progresses toward its last coal plant closure milestone.

Ten years ago, IHS Markit estimates that Alberta's grid contributed about 900 kilograms of carbon dioxide equivalent per megawatt-hour of energy generation.

"That (figure is) really representing the dominance and role of coal in that grid," Birn said.

Current estimates show that figure is closer to 600 kilograms of CO2 equivalent.

"That means the power you and I are using is less carbon-intensive," Birn said, adding that figure will continue to fall over the next couple of years.

RENEWABLES HERE TO STAY
While many debate whether Alberta's energy is getting clean enough fast enough, Birn believes change is coming.

"It's been a half-decade of incredible price volatility in the oil market which had really dominated this sector and region," the analyst said.

"When I think of the future, I see the power sector building on large-scale renewables, which means decarbonization, and that provides an opportunity for those tech companies looking for clean energy places to land facilities."

Coal and natural gas are considered baseline assets by the AESO, where generation capacity does not shift dramatically, though some utilities report declining coal returns in other markets.

"Wind is a variable resource. It will generate when the wind is blowing, and it obviously won't when the wind is not," Deising said. "Wind and solar can ramp quickly, but they can drop off quite quickly, and we have to be prepared.

"We factor that into our daily planning and assessments," he added. "We follow those trends and know where the renewables are going to show up on the system, how many renewables are going to show up."

Deising says one wind plant in Alberta currently has an energy storage capacity to preserve renewably generated electricity during summer demand records and peak hours as needed. As the technology becomes more affordable, he expects more plants to follow suit.

"As a system operator, our job is to make sure as (the grid) is evolving we can continue to provide reliable power to Albertans at every moment every day," Deising said. "We just have to watch the system more carefully."

2022 US Renewable Power Milestone highlights EIA data: wind and solar outpaced coal and nuclear, hydropower contributed, with falling levelized costs, grid integration, battery storage, and transmission upgrades shaping affordable, reliable clean power growth.

Key Points

The year US renewables, led by wind and solar, generated more power than coal and nuclear, per EIA.

✅ Wind and solar rose; levelized costs fell 70%-90% over decade

✅ Renewables surpassed coal and nuclear in 2022 per EIA

✅ Grid needs storage and transmission to manage intermittency

Electricity generated from renewables surpassed coal in the United States for the first time in 2022, as wind and solar surpassed coal nationwide, the U.S. Energy Information Administration has announced.

Renewables also surpassed nuclear generation in 2022 after first doing so last year, and wind and solar together generated more electricity than nuclear for the first time in the United States.

Growth in wind and solar significantly drove the increase in renewable energy and contributed 14% of the electricity produced domestically in 2022, with solar producing about 4.7% of U.S. power overall. Hydropower contributed 6%, and biomass and geothermal sources generated less than 1%.

“I’m happy to see we’ve crossed that threshold, but that is only a step in what has to be a very rapid and much cheaper journey,” said Stephen Porder, a professor of ecology and assistant provost for sustainability at Brown University.

California produced 26% of the national utility-scale solar electricity followed by Texas with 16% and North Carolina with 8%.

The most wind generation occurred in Texas, which accounted for 26% of the U.S. total, while wind is now the most-used renewable electricity source nationwide, followed by Iowa (10%) and Oklahoma (9%).

“This booming growth is driven largely by economics,” said Gregory Wetstone, president and CEO of the American Council on Renewable Energy, as renewables became the second-most prevalent U.S. electricity source in 2020 nationwide. “Over the past decade, the levelized cost of wind energy declined by 70 percent, while the levelized cost of solar power has declined by an even more impressive 90 percent.”

“Renewable energy is now the most affordable source of new electricity in much of the country,” added Wetstone.

The Energy Information Administration projected that the wind share of the U.S. electricity generation mix will increase from 11% to 12% from 2022 to 2023 and that solar will grow from 4% to 5% during the period, and renewables hit a record 28% share in April according to recent data. The natural gas share is expected to remain at 39% from 2022 to 2023, and coal is projected to decline from 20% last year to 17% this year.

“Wind and solar are going to be the backbone of the growth in renewables, but whether or not they can provide 100% of the U.S. electricity without backup is something that engineers are debating,” said Brown University’s Porder.

Many decisions lie ahead, he said, as the proportion of renewables that supply the energy grid increases, with renewables projected to soon be one-fourth of U.S. electricity generation over the near term.

This presents challenges for engineers and policy-makers, Porder said, because existing energy grids were built to deliver power from a consistent source. Renewables such as solar and wind generate power intermittently. So battery storage, long-distance transmission and other steps will be needed to help address these challenges, he said.

USAID GE Mobile Power Plant Ukraine supplies 28MW of emergency power and distributed generation to bolster energy security, grid resilience, and critical infrastructure reliability across cities and regions amid ongoing attacks.

Key Points

A 28MW GE gas turbine from USAID providing mobile, distributed power to strengthen Ukraine's grid resilience.

✅ 28MW GE gas turbine; power for 100,000 homes

✅ Mobile deployment to cities and regions as needed

✅ Supports hospitals, schools, and critical infrastructure

Deputy U.S. Administrator Isobel Coleman announced during her visit to Kyiv that the U.S. Agency for International Development (USAID) has provided the Government of Ukraine with a mobile gas turbine power plant purchased from General Electric (GE), as discussions of a possible agreement on power plant attacks continue among stakeholders.

The mobile power plant was manufactured in the United States by GE’s Gas Power business and has a total output capacity of approximately 28MW, which is enough to provide the equivalent electricity to at least 100,000 homes. This will help Ukraine increase the supply of electricity to homes, hospitals, schools, critical infrastructure providers, and other institutions, as the country has even resumed electricity exports in recent months. The mobile power plant can be operated in different cities or regions depending on need, strengthening Ukraine’s energy security amid the Russian Federation’s continuing strikes against critical infrastructure.   

Since the February 2022 full-scale invasion of Ukraine, and particularly since October 2022, the Russian Federation has deliberately targeted critical civilian heating, power, and gas infrastructure in an effort to weaponize the winter, raising nuclear risks to grid stability noted by international monitors. Ukraine has demonstrated tremendous resilience in the wake of these attacks, with utility workers routinely risking their lives to repair the damage, often within hours of air strikes, even as Russia builds power lines to reactivate the Zaporizhzhia plant to influence the energy situation.

The collaboration between USAID and GE reflects the U.S. government’s emphasis on engaging American private sector expertise and procuring proven and reliable equipment to meet Ukraine’s needs. Since the start of Putin’s full-scale war against Ukraine, USAID has both directly procured equipment for Ukraine from American companies and engaged the private sector in partnerships to meet Ukraine’s urgent wartime needs, with U.S. policy debates such as a proposal on Ukraine’s nuclear plants drawing scrutiny.

This mobile power plant is the latest example of USAID assistance to Ukraine’s energy sector since the start of the Russian Federation’s full-scale invasion, during which Ukraine has resumed electricity exports as conditions improved. USAID has already delivered more than 1,700 generators to 22 oblasts across Ukraine, with many more on the way. These generators ensure electricity and heating for schools, hospitals, accommodation centers for internally-displaced persons, district heating companies, and water systems if and when power is knocked out by the Russian Federation’s relentless, systematic and cruel attacks against critical civil infrastructure. USAID has invested $55 million in Ukraine’s heating infrastructure to help the Ukrainian people get through winter. This support will benefit up to seven million Ukrainians by supporting repairs and maintenance of pipes and other equipment necessary to deliver heating to homes, hospitals, schools, and businesses across Ukraine. USAID’s assistance builds on over two decades of support to Ukraine to strengthen the country’s energy security, complementing growth in wind power that is harder to destroy.

California has recently been awarded over $500 million in federal funds to significantly improve and modernize its power grid. This substantial investment marks a pivotal step in addressing the state’s ongoing energy challenges, enhancing grid resilience, and supporting its ambitious climate goals. The funding, announced by federal and state officials, is set to bolster California’s efforts to upgrade its electrical infrastructure, integrate renewable energy sources, and ensure a more reliable and sustainable energy system for its residents.

California's power grid has faced numerous challenges in recent years, including extreme weather events, high energy demand, and an increasing reliance on renewable energy sources. The state's electrical infrastructure has struggled to keep pace with these demands, leading to concerns about reliability, efficiency, and the capacity to handle new energy technologies. The recent federal funding is a critical component of a broader strategy to address these issues and prepare the grid for future demands.

The $500 million in federal funds is part of a larger initiative to support energy infrastructure projects across the United States, including a Washington state grant that strengthens regional infrastructure. The investment aims to modernize aging grid systems, improve energy efficiency, and enhance the integration of renewable energy sources. For California, this funding represents a significant opportunity to address several key areas of concern in its power grid.

One of the primary objectives of the funding is to enhance the resilience of the power grid. California has experienced a series of extreme weather events, including wildfires and heatwaves, driven in part by climate change impacts across the U.S., which have put considerable strain on the electrical infrastructure. The new investment will support projects designed to strengthen the grid’s ability to withstand and recover from these events. This includes upgrading infrastructure to make it more robust and less susceptible to damage from natural disasters.

Another key focus of the funding is the integration of renewable energy sources. California is a leader in the adoption of solar and wind energy, and the state has set ambitious goals for increasing its use of clean energy. However, integrating these variable energy sources into the grid presents technical challenges, including ensuring a stable and reliable power supply. The federal funds will be used to develop and deploy advanced technologies that can better manage and store renewable energy, such as battery storage systems, improving the overall efficiency and effectiveness of the grid.

In addition to resilience and renewable integration, the funding will also support efforts to modernize grid infrastructure. This includes upgrading transmission and distribution systems, implementing smarter electricity infrastructure and smart grid technologies, and enhancing grid management and control systems. These improvements are essential for creating a more flexible and responsive power grid that can meet the evolving needs of California’s energy landscape.

The investment in grid modernization also aligns with California’s broader climate goals. The state has set targets to reduce greenhouse gas emissions and increase the use of clean energy sources as it navigates keeping the lights on during its energy transition. By improving the power grid and supporting the integration of renewable energy, California is making progress toward achieving these goals while also creating jobs and stimulating economic growth.

The allocation of federal funds comes at a crucial time for California. The state has faced significant challenges in recent years, including power outages, energy reliability issues, and increasing energy costs that make repairing California's grid especially complex today. The new funding is expected to address many of these concerns by supporting critical infrastructure improvements and ensuring that the state’s power grid can meet current and future demands.

Federal and state officials have expressed strong support for the funding and its potential impact. The investment is seen as a major step forward in creating a more resilient and sustainable energy system for California. It is also expected to serve as a model for other states facing similar challenges in modernizing their power grids and integrating renewable energy sources.

The federal funding is part of a broader push to address infrastructure needs across the country. The Biden administration has prioritized investment in energy infrastructure, including a $34 million DOE initiative supporting grid improvements, as part of its broader agenda to combat climate change and build a more sustainable economy. The funding for California’s power grid is a reflection of this commitment and an example of how federal resources can support state and local efforts to improve infrastructure and address pressing energy challenges.

In summary, California’s receipt of over $500 million in federal funds represents a significant investment in the state’s power grid. The funding will support efforts to enhance grid resilience, integrate renewable energy sources, and modernize infrastructure. As California continues to face challenges related to extreme weather, energy reliability, and climate goals, this investment will play a crucial role in building a more reliable, efficient, and sustainable energy system. The initiative also highlights the importance of federal support in addressing infrastructure needs and advancing environmental and economic goals.
