HV insulator coating helps wind power flow

EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.

Key Points

EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.

✅ Extends reactor operation via inspections and component upgrades

✅ Addresses gas shortages, price volatility, and winter supply risks

✅ Requires national regulator approval and cost-benefit analysis

Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.

Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.

Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.

Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.

Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.

Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.

That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.

Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.

U.S. Wind Generation surpassed hydroelectric output in 2019, EIA data shows, becoming the top renewable electricity source, driven by PTC incentives, expanded capacity, and utility-scale projects across states, boosting the national electricity mix.

Key Points

U.S. Wind Generation is the nation's top renewable, surpassing hydro as EIA-tracked capacity grows under PTC incentives.

✅ EIA: wind topped hydro in 2019, over 300M MWh generated

✅ PTC credits spurred growth in utility-scale wind projects

✅ 103 GW installed; 77% added in the last decade

Last year saw wind power surging in the U.S. to overtake hydroelectric generation for the first time, according to data from the U.S. Energy Information Administration (EIA).

Released Wednesday, the figures from the EIA’s “Electric Power Monthly” report show that yearly wind generation hit a little over 300 million megawatt hours (MWh) in 2019. This was roughly 26 million MWh more than hydroelectric production.

Wind now represents the “most-used renewable electricity generation source” in the U.S., the EIA said, and renewables hit a 28% monthly record in April in later data.

Overall, total renewable electricity generation — which includes sources such as solar's 4.7% share in 2022 as one example, geothermal and landfill gas — at utility scale facilities hit more than 720 million MWh in 2019, compared to just under 707 million MWh in 2018. To put things in perspective, generation from coal came to more than 966 million MWh in 2019, while renewables surpassed coal in 2022 nationally according to later analyses.

According to the EIA’s “Today in Energy” briefing, which was also published Wednesday, generation from wind power has grown “steadily” across the last decade, and by 2020, renewables became the second-most prevalent source in the U.S. power mix.

This, it added, was partly down to the extension of the Production Tax Credit, or PTC, amid favorable government plans supporting solar and wind growth. According to the EIA, the PTC is a system which gives operators a tax credit per kilowatt hour of renewable electricity production. It applies for the first 10 years of a facility’s operation.

At the end of 2019, the country was home to 103 gigawatts (GW) of wind capacity, with 77% of this being installed in the last decade, and wind capacity surpassed hydro in 2016 according to industry data. The U.S. is home 80 GW of hydroelectric capacity, according to the EIA.

“The past decade saw a steady increase in wind capacity across the country and we capped the decade with a monumental achievement for the industry in reaching more than 100 GW,” Tom Kiernan, the American Wind Energy Association’s CEO, said in a statement issued Thursday.

“And more wind energy is coming, as the industry is well into investing $62 billion in new projects over the next few years that put us on the path to achieving 20 percent of the nation’s electricity mix in 2030,” Kiernan went on to state.

“As a result, wind is positioned to remain the largest renewable energy generator in the country for the foreseeable future.”

Atlin Hydro and Transmission Project delivers First Nation-led clean energy via hydropower to the Yukon grid, replacing diesel, cutting emissions, and creating jobs, with a 69-kV line from Atlin, B.C., supplying about 35 GWh annually.

Key Points

A First Nation-led 8.5 MW hydropower and 69-kV line supplying clean energy to the Yukon, reducing diesel use.

✅ 8.5 MW capacity; ~35 GWh annually to Yukon grid

✅ 69-kV, 92 km line links Atlin to Jakes Corner

✅ Creates 176 construction jobs; cuts diesel and emissions

A First Nation-led clean-power generation project for British Columbia’s Northwest will provide a significant economic boost and good jobs for people in the area, as well as ongoing revenue from clean energy sold to the Yukon.

“This clean-energy project has the potential to be a win-win: creating opportunities for people, revenue for the community and cleaner air for everyone across the Northwest,” said Premier John Horgan. “That’s why our government is proud to be working in partnership with the Taku River Tlingit First Nation and other levels of government to make this promising project a reality. Together, we can build a stronger, cleaner future by producing more clean hydropower to replace fossil fuels – just as they have done here in Atlin.”

The Province is contributing $20 million toward a hydroelectric generation and transmission project being developed by the Taku River Tlingit First Nation (TRTFN) to replace diesel electricity generation in the Yukon, which is also supported by the Government of Yukon and the Government of Canada, and comes as BC Hydro demand fell during COVID-19 across the province.

“Renewable-energy projects are helping remote communities reduce the use of diesel for electricity generation, which reduces air pollution, improves environmental outcomes and creates local jobs,” said Bruce Ralston, Minister of Energy, Mines and Low Carbon Innovation. “This project will advance reconciliation with TRTFN, foster economic development in Atlin and support intergovernmental efforts to reduce greenhouse gas emissions.”

TRTFN is based in Atlin with territory in B.C., the Yukon, and Alaska. TRTFN is an active participant in clean-energy development and, since 2009, has successfully replaced diesel-generated electricity in Atlin with a 2.1-megawatt (MW) hydro facility amid oversight issues such as BC Hydro misled regulator elsewhere in the province today.

TRTFN owns the Tlingit Homeland Energy Limited Partnership (THELP), which promotes economic development through clean energy. THELP plans to expand its hydro portfolio by constructing the Atlin Hydro and Transmission Project and selling electricity to the Yukon via a new transmission line, in a landscape shaped by T&D rates decisions in jurisdictions like Ontario for cost recovery.

The Government of Yukon is requiring its Yukon Energy Corporation (YEC) to generate 97% of its electricity from renewable resources by 2030. This project provides an opportunity for the Yukon government to reduce reliance on diesel generators and to meet future load growth, at a time when Manitoba Hydro's debt pressures highlight utility cost challenges.

The new transmission line between Atlin and the Yukon grid will include a fibre-optic data cable to support facility operations, with surplus capacity that can be used to bring high-speed internet connectivity to Atlin residents for the first time.

“Opportunities like this hydroelectricity project led by the Taku River Tlingit First Nation is a great example of identifying and then supporting First Nations-led clean-energy opportunities that will support resilient communities and provide clean economic opportunities in the region for years to come. We all have a responsibility to invest in projects that benefit our shared climate goals while advancing economic reconciliation.” said George Heyman, Minister of Environment and Climate Change Strategy.

“Thank you to the Government of British Columbia for investing in this important project, which will further strengthen the connection between the Yukon and Atlin. This ambitious initiative will expand renewable energy capacity in the North in partnership with the Taku River Tlingit First Nation while reducing the Yukon’s emissions and ensuring energy remains affordable for Yukoners.“ said Sandy Silver, Premier of Yukon.

“The Atlin Hydro Project represents an important step toward meeting the Yukon’s growing electricity needs and the renewable energy targets in the Our Clean Future strategy. Our government is proud to contribute to the development of this project and we thank the Government of British Columbia and all partners for their contributions and commitment to renewable energy initiatives. This project demonstrates what can be accomplished when communities, First Nations and federal, provincial and territorial governments come together to plan for a greener economy and future.” said John Streicker, Minister Responsible for the Yukon Development Corporation. 

“Atlin has enjoyed clean and renewable energy since 2009 because of our hydroelectric project. Over its lifespan, Atlin’s hydro opportunity will prevent more than one million tonnes of greenhouse gases from being created to power the southern Yukon. We are looking forward to the continuation of this project. Our collective dream is to meet our environmental and economic goals for the region and our local community within the next 10 years. We are so grateful to all our partners involved for their financial support, as we continue onward in creating an energy efficient and sustainable North.” said Charmaine Thom, Taku River Tlingit First Nation spokesperson.

Quick Facts:

• The 8.5-MW project is expected to provide an average of 35 gigawatt hours of energy annually to the Yukon. To accomplish this, TRTFN plans to leverage the existing water storage capability of Surprise Lake, add new infrastructure, and send power 92 km north to Jakes Corner, Yukon, along a new 69-kilovolt transmission line.
• The project is expected to cost $253 - 308.5 million, the higher number reflecting recently estimated impacts of inflation and supply chain cost escalation, alongside sector accounting concerns such as deferred BC Hydro costs noted in recent reports.
• The project is expected to have a positive impact on local and provincial economic development in the form of, even as governance debates like Manitoba Hydro board changes draw attention elsewhere:
• 176 full-time positions during construction;
• six to eight full-time positions in operations and maintenance over 40 years; and
• increased business for B.C. contractors.
• Territorial and federal funders have committed $151.1 million to support the project, most recently the $32.2 million committed in the 2022 federal bdget.

Ontario electricity shortage is looming, RBC and IESO warn, as EV electrification surges, Pickering nuclear faces delays, and gas plants backstop expiring renewables, raising GHG emissions and grid reliability concerns across the province.

Key Points

A projected supply shortfall as demand rises from electrification, expiring contracts, and delayed nuclear capacity.

✅ RBC warns shortages as early as 2026, significant by 2030

✅ IESO sees EV-driven demand; 5,000-15,000 MW by 2035

✅ Gas reliance boosts GHGs; Pickering life extension assessed

In a fit of ideological pique, Doug Ford’s government spent more than $200 million to scrap more than 700 green energy projects soon after winning the 2018 election, amid calls to make clean, affordable power a central issue, portraying them as “unnecessary and expensive energy schemes.”

A year later, then Associate Energy Minister Bill Walker defended the decision, declaring, “Ontario has an adequate supply of power right now.”

Well, life moves fast. At the time, scrapping the renewable energy projects was criticized as short-sighted and wasteful, raising doubts about whether Ontario was embracing clean power in a meaningful way. It seems especially so now as Ontario confronts the reality of being short of electricity in the coming years.

How short? A recent report by RBC calls the situation “urgent,” saying that Canada’s most populous province could face energy shortages as early as 2026. As contracts for non-hydro renewables and gas plants expire, the shortages could be “significant” by 2030, the bank report said, with grid greening costs adding to the challenge.

The Independent Electricity System Operator (IESO), which manages the electrical supply in Ontario, says demand for electricity could rise at rates not seen in many years, as the government moves to add new gas plants to boost capacity. “Economic growth coming out of the pandemic, along with electrification in many sectors, is driving energy use up,” the agency said in a December assessment.

The good news is that demand is being driven, in part, by the transition to “green” power – carbon-emission-free electricity – by sectors such as transportation and manufacturing. That will help reduce emissions. Yet meeting that demand presents some challenges, prompting the province to outline a plan to address growing needs across the system. The shift to electric vehicles alone is expected to cause a spike in demand starting in 2030. By 2035, the province could need an additional 5,000 to 15,000 megawatts of electricity, the IESO estimates.

It was perhaps no surprise then to see the province announce last week that it wants to delay the long-planned closing of the Pickering nuclear plant by a year to 2026, even as others note the station is slated to close as planned. Operations beyond that would require refurbishing the facility. The province said it’s taking a fresh look at whether that would make sense to extend its life by another 30 years.

In the interim, the province will be forced to dramatically ramp up its reliance on natural gas plants for electricity generation – and, as analysts warn, Ontario’s power mix could get dirtier even before new non-emitting capacity is built, and in the process, increase greenhouse gas emissions from the energy grid by 400 per cent. Broader electrification is expected to produce “significant” GHG emissions reductions in Ontario over the next two decades, according to the IESO. Still, it’s working at cross-purposes if your electric car is charged by electricity generated by fossil fuels.

Nuclear decarbonization leverages low-carbon electricity, process heat, and hydrogen from advanced reactors and SMRs to electrify industry, buildings, and transport, supporting net-zero strategies and grid flexibility alongside renewables with dispatchable baseload capacity.

Key Points

Nuclear decarbonization uses reactors to supply low-carbon power, heat, and hydrogen, cutting emissions across industry.

✅ Advanced reactors and SMRs enable high-temperature process heat

✅ Nuclear-powered electrolysis and HTSE produce low-carbon hydrogen

✅ District heating from reactors reduces pollution and coal use

By Dr Henri Paillere, Head of the Planning and Economics Studies Section of the IAEA

Decarbonising the power sector will not be sufficient to achieving net-zero emissions, with assessments indicating nuclear may be essential across sectors. We also need to decarbonise the non-power sectors - transport, buildings and industry - which represent 60% of emissions from the energy sector today. The way to do that is: electrification with low-carbon electricity as much as possible; using low-carbon heat sources; and using low-carbon fuels, including hydrogen, produced from clean electricity.
The International Energy Agency (IEA) says that: 'Almost half of the emissions reductions needed to reach net zero by 2050 will need to come from technologies that have not reached the market today.' So there is a need to innovate and push the research, development and deployment of technologies. That includes nuclear beyond electricity.

Today, most of the scenario projections see nuclear's role ONLY in the power sector, despite ongoing debates over whether nuclear power is in decline globally, but increased electrification will require more low-carbon electricity, so potentially more nuclear. Nuclear energy is also a source of low-carbon heat, and could also be used to produce low-carbon fuels such as hydrogen. This is a virtually untapped potential.

There is an opportunity for the nuclear energy sector - from advanced reactors, next-gen nuclear small modular reactors, and non-power applications - but it requires a level playing field, not only in terms of financing today's technologies, but also in terms of promoting innovation and supporting research up to market deployment. And of course technology readiness and economics will be key to their success.

On process heat and district heating, I would draw attention to the fact there have been decades of experience in nuclear district heating. Not well spread, but experience nonetheless, in Russia, Hungary and Switzerland. Last year, we had two new projects. One floating nuclear power plant in Russia (Akademik Lomonosov), which provides not only electricity but district heating to the region of Pevek where it is connected. And in China, the Haiyang nuclear power plant (AP1000 technology) has started delivering commercial district heating. In China, there is an additional motivation to reducing emissions, namely to cut air pollution because in northern China a lot of the heating in winter is provided by coal-fired boilers. By going nuclear with district heating they are therefore cutting down on this pollution and helping with reducing carbon emissions as well. And Poland is looking at high-temperature reactors to replace its fleet of coal-fired boilers and so that's a technology that could also be a game-changer on the industry side.

There have also been decades of research into the production of hydrogen using nuclear energy, but no real deployment. Now, from a climate point of view, there is a clear drive to find substitute fuels for the hydrocarbon fuels that we use today, and multiple new nuclear stations are seen by industry leaders as necessary to meet net-zero targets. In the near term, we will be able to produce hydrogen with electrolysis using low-carbon electricity, from renewables and nuclear. But the cheapest source of low-carbon power is from the long-term operation of existing nuclear power plants which, combined with their high capacity factors, can give the cheapest low-carbon hydrogen of all.

In the mid to long term, there is research on-going with processes that are more efficient than low-temperature electrolysis, which is high temperature steam electrolysis or thermal splitting of water. These may offer higher efficiencies and effectiveness but they also require advanced reactors that are still under development. Demonstration projects are being considered in several countries and we at the IAEA are developing a publication that looks into the business opportunities for nuclear production of hydrogen from existing reactors. In some countries, there is a need to boost the economics of the existing fleet, especially in the electricity systems where you have low or even negative market prices for electricity. So, we are looking at other products that have higher values to improve the competitiveness of existing nuclear power plants.

The future means not only looking at electricity, but also at industry and transport, and so integrated energy systems. Electricity will be the main workhorse of our global decarbonisation effort, but through heat and hydrogen. How you model this is the object of a lot of research work being done by different institutes and we at the IAEA are developing some modelling capabilities with the objective of optimising low-carbon emissions and overall costs.

This is just a picture of what the future might look like: a low-carbon power system with nuclear lightwater reactors (large reactors, small modular reactors and fast reactors) drawing on the green industrial revolution reactor waves in planning; solar, wind, anything that produces low-carbon electricity that can be used to electrify industry, transport, and the heating and cooling of buildings. But we know there is a need for high-temperature process steam that electricity cannot bring but which can be delivered directly by high-temperature reactors. And there are a number of ways of producing low-carbon hydrogen. The beauty of hydrogen is that it can be stored and it could possibly be injected into gas networks that could be run in the future on 100% hydrogen, and this could be converted back into electricity.

So, for decarbonising power, there are many options - nuclear, hydro, variable renewables, with renewables poised to surpass coal in global generation, and fossil with carbon capture and storage - and it's up to countries and industries to invest in the ones they prefer. We find that nuclear can actually reduce the overall cost of systems due to its dispatchability and the fact that variable renewables have a cost because of their intermittency. There is a need for appropriate market designs and the role of governments to encourage investments in nuclear.

Decarbonising other sectors will be as important as decarbonising electricity, from ways to produce low-carbon heat and low-carbon hydrogen. It's not so obvious who will be the clear winners, but I would say that since nuclear can produce all three low-carbon vectors - electricity, heat and hydrogen - it should have the advantage.
We at the IAEA will be organising a webinar next month with the IEA looking at long-term nuclear projections in a net-zero world, building on IAEA analysis on COVID-19 and low-carbon electricity insights. That will be our contribution from the point of view of nuclear to the IEA's special report on roadmaps to net zero that it will publish in May.

Electrically Smart Roads integrate solar road surfaces, inductive charging, IoT sensors, AI analytics, and V2X to power lighting, deicing, and monitoring, reducing grid dependence while enabling dynamic EV charging and real-time traffic management.

Key Points

Electrically smart roads generate power, sense conditions, and charge EVs using solar, IoT, AI, and dynamic infrastructure.

✅ Solar surfaces, verges, and gantries generate on-site electricity

✅ Inductive lanes enable dynamic EV charging at highway speeds

✅ Embedded IoT sensors and AI deliver real-time traffic insights

As more and more capabilities are added to roads instead of simply covering a country with extra roads, they are starting to make their own electricity, notably as solar road surface but then with added silent wind turbines, photovoltaic verges and barriers and more.

That toll gate, street light and traffic monitoring system all need electricity. Later, roads that deice and charge vehicles at speed will need huge amounts of electricity. For now, electricity for road systems is provided by very expensive infrastructure to the grid, and grid flexibility for EVs remains a concern, except for a few solar/ wind street lights in China and Korea for example. However, as more and more capabilities are added to roads instead of simply covering a country with extra roads, they are starting to make their own electricity, notably as solar road surface but then with added silent wind turbines, photovoltaic verges and barriers and more. There is also highly speculative work in the USA and UK on garnering power from road surface movement using piezoelectrics and electrodynamics and even its heat.

China plans to create an intelligent transport system by 2030. The country hopes to build smart roads that will not only be able to charge electric cars as they drive but also monitor temperature, traffic flow and weight load using artificial intelligence. Indeed, like France, the Netherlands and the USA, where U.S. EV charging capacity is under scrutiny, it already has trials of extended lengths of solar road which cost no more than regular roads. In an alternative approach, vehicles go under tunnels of solar panels that also support lighting, light-emitting signage and monitoring equipment using the electricity made where it is needed. See the IDTechEx Research report, Electrically Smart Roads 2018-2028 for more.

Raghu Das, CEO of IDTechEx says, "The spiral vertical axis wind turbines VAWT in Asia rarely rotate because they are too low but much higher versions are planned on large UK roadside vehicle charging centres that should work well. H shaped VAWT is also gaining traction - much slower and quieter than the propeller shape which vibrates and keeps you awake at night in an urban area.

The price gap between the ubiquitous polycrystalline silicon solar cell and the much more efficient single crystal silicon is narrowing. That means that road furniture such as bus shelters and smart gantries will likely go for more solar rather than adding wind power in many cases, a shift mirrored by connected solar tech in homes, because wind power needs a lot of maintenance and its price is not dropping as rapidly."

The IDTechEx Research report, Off Grid Electric Vehicle Charging: Zero Emission 2018-2028 analyses that aspect, while vehicle-to-grid strategies may complement grid resources. The prototype of a smart road is already in place on an expressway outside of Jinan, providing better traffic updates as well as more accurate mapping. Verizon's IoT division has launched a project around intelligent asphalt, which it thinks has the potential to significantly reduce fossil fuel emissions and save time by reducing up to 44% of traffic backups. It has partnered with Sacramento, California, to test this theory.

"By embedding sensors into the pavement as well as installing cameras on traffic lights, we will be able to study and analyze the flow of traffic. Then, we will take all of that data and use it to optimize the timing of lights so that traffic flows easier and travel times are shorter," explains Sean Harrington, vice president of Verizon Smart Communities.

Colorado's Department of Transportation has recently announced its intention to be the first state to pilot smart roads by striking a five-year deal with a smart road company to test the technology. Like planned auto-deicing roads elsewhere, the aim of this project is, first and foremost, to save lives. The technology will detect when a car suddenly leaves a road and send emergency assistance to the area. The IDTechEx Research report Electrically Smart Roads 2018-2028 describes how others work on real time structural monitoring of roads and embedded interactive lighting and road surface signage.

"Smart pavement can make that determination and send that information directly into a vehicle," Peter Kozinski, director of CDOT's RoadX division, tells the Denver Post. "Data is the new asphalt of transportation."   Sensors, processors and other technology are embedded in the Colorado road to extend capability beyond accidents and reach into better road maintenance. Fast adoption relies on the ability to rapidly install sensor-laden pavement or lay concrete slabs. Attention therefore turns to fast adaptation of existing roads. Indeed, even for the heavy coil arrays used for dynamic vehicle charging, even as state power grids face new challenges, in Israel there are machines that can retrofit into the road surface at a remarkable two kilometres of cut and insert in a day.

"It's hard to imagine that these things are inexpensive, with all the electronics in them," Charles Schwartz, a professor of civil and environmental engineering at the University of Maryland, tells the Denver Post concerning the vehicle sensing project, "but CDOT is a fairly sophisticated agency, and this is an interesting pilot project. We can learn a lot, even if the test is only partially successful."
