Atomic Energy of Canada Limited AECL has reached an important milestone with the first successful completion in Wolsong, South Korea, of the removal and replacement of calandria tubes, pressure tubes and end fittings in a CANDU 6 nuclear reactor.

"This success marks the first time a CANDU 6 reactor has had all of the fuel channels removed and replaced," says Hugh MacDiarmid, AECL's President and CEO, "bringing us one step closer to completing the project and allowing the Wolsong reactor to continue building on its excellent operating performance record for another 30 years."

AECL developed hundreds of specialized tools and systems for this first-of-a-kind groundbreaking work. The tools' robotically driven movements are intricate and precise, and designed to be used in a radioactive environment.

AECL began work on the South Korean reactor in June 2009 to replace all 380 calandria tubes. Each calandria tube is approximately six metres long by 13 centimetres in diameter. Made of zirconium-alloy, the tubes house the reactor's 380 fuel channels. The fuel channels connect to end fittings on each fuel channel assembly to circulate heavy water coolant between the reactor and steam generators.

"We have 170 Canadian employees working in Korea on the Wolsong project, and they are focused on successfully completing their work in a safe, professional, quality manner," said Ramzi Fawaz, AECL Senior Vice-President of Operations. "Their experience gained at Wolsong will serve us well in delivering our current and future refurbishment projects."

The next stage of work at Wolsong is to remove the multi-tonne tooling systems and the work platforms supporting them before feeder installation begins. This will be managed jointly by AECL and the client, Korea Hydro & Nuclear Power Company Ltd. KHNP. The reactor is now on track to return to service for Korea's summer peak demand next year.

US Dept. of Energy awards Washington state $23.4 million to strengthen infrastructure

Washington Grid Resilience Grant funds DOE-backed modernization to harden Washington's electric grid against extreme weather, advancing clean energy, affordable and reliable electricity, and community resilience under the Bipartisan Infrastructure Law via projects and utility partnerships.

 

Key Points

A $23.4M DOE grant to modernize Washington's grid, boost weather resilience, and deliver clean, reliable power.

✅ Targets outages, reliability, and community resilience statewide.

✅ Prioritizes disadvantaged areas and quality clean energy jobs.

✅ Backed by Bipartisan Infrastructure Law and DOE funding.

 

Washington state has received a $23.4 million Grid Resilience State and Tribal Formula Grant from the U.S. Department of Energy (DOE) to modernize the electric grid through smarter electricity infrastructure and reduce impacts due to extreme weather and natural disasters. Grid Resilience State and Tribal Formula Grants aim to ensure the reliability of power sector infrastructure so that communities have access to affordable, reliable, clean electricity.

“Electricity is an essential lifeline for communities. Improving our systems by reducing disruptive events is key as we cross the finish line of a 100% clean electricity grid and ensure equitable benefits from the clean energy economy reach every community,” said Gov. Jay Inslee.

The federal funding for energy resilience will enhance and expand ongoing current grid modernization and resilience efforts throughout the state. For example, working directly with rural and typical end-of-the-line customers to develop resilience plans and collaborating with communities and utilities, including smart city efforts in Spokane as examples, on building resilient and renewable infrastructure for essential services.

“This is a significant opportunity to supplement our state investments in building a robust, resilient electric grid that supports our long-term vision for clean, affordable and reliable electricity – the foundation for economic growth and job creation that strengthens our communities and keeps Washington globally competitive. It shows once again that we are maximizing the federal funding being made available by the Biden-Harris Administration to invest in the country’s infrastructure,” said Washington State Department of Commerce Director Mike Fong.

Across the border, British Columbia's clean energy shift adds regional momentum for resilient, low-carbon power.

Goals include:

Reducing the frequency, duration and impact of outages as climate change impacts on the grid intensify while enhancing resiliency in historically disadvantaged communities.
Strengthening prosperity by expanding well-paying, safe clean energy jobs accessible to all workers and ensuring investments have a positive effect on quality job creation and equitable economic development.

Building a community of practice and maximizing project scalability by identifying pathways for scaling innovations such as integrating solar into the grid across programs.

“The Grid Resilience Formula Grants will enable communities in Washington to protect households and businesses from blackouts or power shutdowns during extreme weather,” said Maria Robinson, Director, Grid Deployment Office, U.S. Department of Energy. “Projects selected through this program will benefit communities by creating good-paying jobs to deliver clean, affordable, and reliable energy across the country.”

DOE has also announced $34 million for grid improvements to bolster reliability nationwide.

“An innovative, reliable, and efficient power grid is vital to Washington’s continued economic growth and for community resilience especially in disadvantaged areas,” said U.S. Rep. Strickland, Co-Lead of the bipartisan Grid Innovation Caucus. “The funding announced today will invest in our energy grid, support good-paying jobs, and means a cleaner, more energy-efficient future.”

Funded through the Bipartisan Infrastructure Law and administered by DOE’s Grid Deployment Office, with related efforts such as California grid upgrades advancing nationwide, the Grid Resilience State and Tribal Formula Grants distribute funding to states, territories, and federally recognized Indian Tribes, over five years based on a formula that includes factors such as population size, land area, probability and severity of disruptive events, and a locality’s historical expenditures on mitigation efforts. Priority will be given to projects that generate the greatest community benefit providing clean, affordable, and reliable energy.

UN: Renewable Energy Ambition in NDCs must Double by 2030

NDC Renewable Energy Ambition drives COP25 calls to align with the Paris Agreement, as IRENA urges 2030 targets toward 7.7 TW, accelerating decarbonization, energy transition, socio-economic benefits, and scalable renewables in Nationally Determined Contributions.

 

Key Points

Raised 2030 renewable targets in NDCs to meet Paris goals, reaching 7.7 TW efficiently and speeding decarbonization.

✅ Double current NDC renewables to align with 7.7 TW by 2030

✅ Cost effective pathway with jobs, growth, welfare gains

✅ Accelerates decarbonization and energy access per UN goals

 

We need an oracle to get us out of this debacle. The UN climate group has met for the 25th time. Will anything ever change?

Countries are being urged to significantly raise renewable energy ambition and adopt targets to transform the global energy system in the next round of Nationally Determined Contributions (NDCs), according to a new IRENA report by the International Renewable Energy Agency (IRENA) that will be released at the UN Climate Change Conference (COP25) in Madrid.

The report will show that renewable energy ambition within NDCs would have to more than double by 2030 to put the world in line with the Paris Agreement goals, cost-effectively reaching 7.7 terawatts (TW) of globally installed capacity by then. Today’s renewable energy pledges under the NDCs are falling short of this, targeting only 3.2 TW, even as over 30% of global electricity is already generated from renewables.

The reportNDCs in 2020: Advancing Renewables in the Power Sector and Beyondwill be released at IRENA’s official side event on enhancing NDCs and raising ambition on 11 December 2019.It will state that with over 2.3 TW installed renewable capacity today, following a record year for renewables in 2016, almost half of the additional renewable energy capacity foreseen by current NDCs has already been installed.

The analysis will also highlight that delivering on increased renewable energy ambition can be achieved in a cost-effective way and with considerable socio-economic benefits across the world.

“Increasing renewable energy targets is absolutely necessary,” said IRENA’s Director-General Francesco La Camera. “Much more is possible. There is a decisive opportunity for policy makers to step up climate action, including a fossil fuel lockdown, by raising ambition on renewables, which are the only immediate solution to meet rising energy demand whilst decarbonizing the economy and building resilience.

“IRENA’s analysis shows that a pathway to a decarbonised economy is technologically possible and socially and economically beneficial,” continued Mr. La Camera.

“Renewables are good for growth, good for job creation and deliver significant welfare benefits. With renewables, we can also expand energy access and help eradicate energy poverty by ensuring clean, affordable and sustainable electricity for all in line with the UN Sustainable Development Agenda 2030.

IRENA will promote knowledge exchange, strengthen partnerships and work with all stakeholders to catalyse action on the ground. We are engaging with countries and regions worldwide, from Ireland's green electricity push to other markets, to facilitate renewable energy projects and raise their ambitions”.

NDCs must become a driving force for an accelerated global energy transformation toward 100% renewable energy globally. The current pledges reflect neither the past decade’s rapid growth nor the ongoing market trends for renewables. Through a higher renewable energy ambition, NDCs could serve to advance multiple climate and development objectives.

$550 Million in Clean Energy Funding to Benefit More than 250 Million Americans

EECBG Program Funding empowers states, Tribes, and local governments with DOE grants to deploy clean energy, energy efficiency, EV infrastructure, and community solar, cutting emissions, lowering utility bills, and advancing net-zero decarbonization.

 

Key Points

EECBG Program Funding is a $550M DOE grant for states, Tribes, and governments to deploy clean energy and efficiency.

✅ Supports EV infrastructure and community solar deployment

✅ Cuts emissions and lowers utility costs via efficiency

✅ Prioritizes Justice40 benefits for underserved communities

 

The Biden-Harris Administration, through the U.S. Department of Energy (DOE), today released a Notice of Intent announcing $550 million to support community-based clean energy in state, Tribal, and local governments — serving more than 250 million Americans. This investment in American communities, through the Energy Efficiency and Conservation Block Grant (EECBG) Program, will support communities across the country to develop local programming and deploy clean energy technologies to cut emissions, advance a 90% carbon-free electricity goal nationwide, and reduce consumers’ energy costs, and help meet President Biden’s goal of a net-zero economy by 2050. 

“This funding is a streamlined and flexible tool for local governments to build their electricity future with clean energy,” said U.S. Secretary of Energy Jennifer M. Granholm. “State, local, and Tribal communities nationwide will be able to leverage this funding to drive greater energy efficiency and conservation practices to lower utility bills and create healthier environments for American families.”   

The EECBG Program will fund 50 states, five U.S. territories, the District of Columbia, 774 Tribes, and 1,878 local governments in a variety of capacity-building, planning, and infrastructure efforts to reduce carbon emissions and energy use and improve energy efficiency in the transportation, building, and other related sectors. For example, communities with this funding can build out electric vehicle infrastructure and deploy community solar to serve areas that otherwise do not have access to electric vehicles or clean energy, particularly through a rural energy security program where appropriate.  

The $550 million made available through the Bipartisan Infrastructure Law (BIL) represents the second time that the EECBG Program has been funded, the first of which was through the American Recovery and Reinvestment Act of 2009. With this most recent funding, communities can build on prior investments and leverage additional clean energy funding from DOE, other federal agencies, and the private sector to achieve sustained impacts, supported by a Clean Electricity Standard where applicable, that can put their communities on a pathway to decarbonization. 

Through the EECBG Program and the Office of State and Community Energy Programs (SCEP), DOE will support the many diverse state, local, and tribal communities across the U.S., including efforts to revitalize coal communities through clean energy, as they implement this funding and other clean energy projects. To ensure no communities are left behind, the program aligns with President’s Justice40 initiative and efforts toward equity in electricity regulation to help ensure that 40% of the overall benefits of clean energy investments go to underserved and overburdened communities.

California's solar energy gains go up in wildfire smoke

California Wildfire Smoke Impact on Solar reduces photovoltaic output, as particulate pollution, soot, and haze dim sunlight and foul panels, cutting utility-scale generation and grid reliability across CAISO during peak demand and heatwaves.

 

Key Points

How smoke and soot cut solar irradiance and foul panels, slashing PV generation and straining CAISO grid operations.

✅ Smoke blocks sunlight; soot deposition reduces panel efficiency.

✅ CAISO reported ~30% drop versus July during peak smoke.

✅ Longer fire seasons threaten solar reliability and capacity planning.

 

Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state, even as U.S. solar generation rose in 2022 nationwide. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.

Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California Independent System Operator (CAISO), which oversees nearly all utility-scale solar energy in California, where wind and solar curtailments have been rising amid grid constraints. It was a 13.4 percent decrease from the same period last year, even though solar capacity in the state has grown about 5 percent since September 2019.

California depends on solar installations for nearly 20 percent of its electricity generation, and has more solar capacity than the next five US states trailing it combined as it works to manage its solar boom sustainably. It will need even more renewable power to meet its goal of 100 percent clean electricity generation by 2045, building on a recent near-100% renewable milestone that underscored the transition. The state’s emphasis on solar power is part of its long-term efforts to avoid more devastating effects of climate change. But in the short term, California’s renewables are already grappling with rising temperatures.

Two records were smashed early this September that contributed to the loss of solar power. California surpassed 2 million acres burned in a single fire season for the first time (1.7 million more acres have burned since then). And on September 15th, small particle pollution reached the highest levels recorded since 2000, according to the California Air Resources Board. Winds that stoked the flames also drove pollution from the largest fires in Northern California to Southern California, where there are more solar farms.

Smaller residential and commercial solar systems were affected, too, and solar panels during grid blackouts typically shut off for safety, although smoke was the primary issue here. “A lot of my systems were producing zero power,” Steve Pariani, founder of the solar installation company Solar Pro Energy Systems, told the San Mateo Daily Journal in September.

As the planet heats up, California’s fire seasons have grown longer, and blazes are tearing through more land than ever before, while grid operators are also seeing rising curtailments as they integrate more renewables. For both utilities and smaller solar efforts, wildfire smoke will continue to darken solar energy’s otherwise bright future, even as it becomes the No. 3 renewable source in the U.S. by generation.

Energy storage poised to tackle grid challenges from rising EVs as mobile chargers bring new flexibility

EV Charging Grid Readiness addresses how rising EV adoption, larger batteries, and fast charging affect electric utilities, using vehicle-to-grid, energy storage, mobile and temporary chargers, and smart charging to mitigate distribution stress.

 

Key Points

Planning and tech to manage EV load growth with V2G, storage and smart charging to avoid overloads on distribution grids.

✅ Lithium-ion costs may drop 60%, enabling new charger models

✅ Mobile and temporary chargers buffer local distribution peaks

✅ Smart charging and V2G defer transformer and feeder upgrades

 

The impacts of COVID-19 likely mean flat electric vehicle (EV) sales this year, but a trio of new reports say the long-term outlook is for strong growth — which means the electric grid and especially state power grids will need to respond.

As EV adoption grows, newer vehicles will put greater stress on the electric grid due to their larger batteries and capacity for faster charging, according to Rhombus Energy Solutions, while a DOE lab finds US electricity demand could rise 38% as EV adoption scales. A new white paper from the company predicts the cost of lithium-ion batteries will drop by 60% over the next decade, helping enable a new set of charging solutions.

Meanwhile, mobile and temporary EV charging will grow from 0.5% to 2% of the charging market by 2030, according to new Guidehouse research. The overall charging market is expected to reach reach almost $16 billion in revenues in 2020 and more than $60 billion by 2030. ​A third report finds long-range EVs are growing their share of the market as well, and charging them could cause stress to electric distribution systems. 

"One can expect that the number of EVs in fleets will grow very rapidly over the next ten years," according to Rhombus' report. But that means many fleet staging areas will have trouble securing sufficient charging capacity as electric truck fleets scale up.

"Given the amount of time it takes to add new megawatt-level power feeds in most cities (think years), fleet EVs will run into a significant 'power crisis' by 2030," according to Rhombus.

"Grid power availability will become a significant problem for fleets as they increase the number of electric vehicles they operate," Rhombus CEO Rick Sander said in a statement. "Integrating energy storage with vehicle-to-grid capable chargers and smart [energy management system] solutions as seen in California grid stability efforts is a quick and effective mitigation strategy for this issue."

Along with energy storage, Guidehouse says a new, more flexible approach to charger deployment enabled by grid coordination strategies will help meet demand. That means chargers deployed by a van or other mobile stations, and "temporary" chargers that can help fleets expand capacity. 

According to Guidehouse, the temporary units "are well positioned to de-risk large investments in stationary charging infrastructure" while also providing charge point networks and service providers "with new capabilities to flexibly supply predictable changes in EV transportation behaviors and demand surges."

"Mobile charging is a bit of a new area in the EV charging scene. It primarily leverages batteries to make chargers mobile, but it doesn't necessarily have to," Guidehouse Senior Research Analyst Scott Shepard told Utility Dive. 

"The biggest opportunity is with the temporary charging format," said Shepard. "The bigger units are meant to be located at a certain site for a period of time. Those units are interesting because they create a little more scale-ability for sites and a little risk mitigation when it comes to investing in a site."

"Utilities could use temporary chargers as a way to provide more resilient service, using these chargers in line with on-site generation," Shepard said.

Increasing rates of EV adoption, combined with advances in battery size and charging rates, "will impact electric utility distribution infrastructure at a higher rate than previously projected," according to new analysis from FleetCarma.

The charging company conducted a study of over 3,900 EVs, illustrating the rapid change in vehicle capabilities in just the last five years. According to FleetCarma, today's EVs use twice as much energy and draw it at twice the power level. The long-range EV has increased as a proportion of new electric vehicle sales from 14% in 2014 to 66% in 2019 in the United States, it found.

Long-range EVs "are very different from older electric vehicles: they are driven more, they consume more energy, they draw power at a higher level and they are less predictable," according to FleetCarma.

Guidehouse analysts say grid modernization efforts and energy storage can help smooth the impacts of charging larger vehicles. 

Mobile and temporary charging solutions can act as a "buffer" to the distribution grid, according to Guidehouse's report, allowing utilities to avoid or defer some transmission and distribution upgrade costs that could be required due to stress on the grid from newer vehicles.

"At a high level, there's enough power and energy to supply EVs with proper management in place," said Shepard. "And in a lot of different locations, those charging deployments will be built in a way that protects the grid. Public fast charging, large commercial sites, they're going to have the right infrastructure embedded."

"But for certain areas of the grid where there is low visibility, there is the potential for grid disruption and questions about whether the UK grid can cope with EV demand," said Shepard. "This has been on the mind of utilities but never realized: overwhelming residential transformers."

As EVs with higher charging and energy capacities are connected to the grid, Shepard said, "you are going to start to see some of those residential systems come under pressure, and probably see increased incidences of having to upgrade transformers." Some residential upgrades can be deferred through smarter charging programs, he added.

Marine Renewables Canada shifts focus towards offshore wind

Marine Renewables Canada Offshore Wind integrates marine renewables, tidal and wave energy, advancing clean electricity, low-carbon power, supply chain development, and regulatory alignment to scale offshore wind energy projects across Canada's coasts and global markets.

 

Key Points

An initiative to grow offshore wind using Canada's marine strengths, shared supply chains, and regulatory synergies.

✅ Leverages tidal and wave energy expertise for offshore wind

✅ Aligns supply chain, safety, and regulatory frameworks

✅ Supports low-carbon power and clean electricity goals

 

With a growing global effort to develop climate change solutions and increase renewable electricity production, including the UK offshore wind growth in recent years, along with Canada’s strengths in offshore and ocean sectors, Marine Renewables Canada has made a strategic decision to grow its focus by officially including offshore wind energy in its mandate.

Marine Renewables Canada plans to focus on similarities and synergies of the resources in order to advance the sector as a whole and ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

“Many of our members working on tidal energy and wave energy projects also have expertise that can service offshore wind projects both domestically and internationally,” says Tim Brownlow, Chair of Marine Renewables Canada. “For us, offshore wind is a natural fit and our involvement will help ensure that Canadian companies and researchers are gaining knowledge and opportunities in the offshore wind sector as it grows.”

Canada has the longest coastlines in the world, giving it huge potential for offshore wind energy development. In addition to the resource, Canada has significant capabilities from offshore and marine industries that can contribute to offshore wind energy projects. The global offshore wind market is estimated to grow by over 650% by 2030 and presents new opportunities for Canadian business.

“The federal government’s recent inclusion of offshore renewables in legislation, including a plan for regulating offshore wind developed by the government, and support for emerging renewable energy technologies are important steps toward building this industry,” says Elisa Obermann, executive director of Marine Renewables Canada. “There are still challenges to address before we’ll see offshore wind energy development in Canada, but we see a great opportunity to get more involved now, increase our experience, and help inform future development.”

Like wave and tidal energy, offshore wind projects operate in harsh marine environments and development presents many of the same challenges and benefits as it does for other marine renewable energy resources. Marine Renewables Canada has recognized that there is significant overlap between offshore wind and wave and tidal energy when it comes to the supply chain, regulatory issues, and the operating environment. The association plans to focus on similarities and synergies of the resources in order to advance the sector as a whole, leveraging Canada’s opportunity in the global electricity market to ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.
