The future of the new European Pressurized Reactor (EPR) designed by Areva SA and French national utility Electricite de France (EDF) has been called into question after a leaked letter sent by a Finnish nuclear watchdog raised safety concerns.

The installation of the first EPR reactor, rated at 1,600 megawatts (MW), is currently under way at the Olkiluoto 3 nuclear power plant site, located on an island off the western coast of Finland. However, the project has been dogged by three years of delays, Greenpeace protests and cost overruns that are estimated to have added up to an additional 50% of the original $4 billion construction budget. Now, a condemning letter from STUK, the Finnish Radiation and Nuclear Safety Authority, to Areva is threatening to delay this and future EPR projects.

The letter to Areva's Chairperson of the Management Board, Anne Lauvergeon, criticizes the company's poor response to "evident errors" that STUK pointed out a year ago regarding the EPR safety systems and other issues. Ironically, the EPR system is promoted by its makers as having superior safety systems compared to other nuclear reactors.

"I want to express my great concern on the lack of progress in the design of Olkiluoto 3 NPP [nuclear power plant] automation," he wrote. "Without a proper design that meets the basic principles of nuclear safety... I see no possibility to approve these important systems for installation," said the letter from Jukka Laaksonen, STUK's Director General. "The systems with highest safety importance are to be designed by Areva NP SAS but unfortunately the attitude or lack of professional knowledge of some persons who speak in the expert meetings on behalf of that organisation prevent... progress in resolving the concerns."

The leaked letter was sent in December 2008. Areva has admitted that it has since sent some, but not all, of the requested documentation demanded by STUK and claims that the company will have done so by the end of June.

This is an alarming development for the new third-generation EPR reactor, because EDF is hoping to use at least four of the reactors at new UK nuclear sites located in Sizewell in Suffolk and Hinkley Point, Somerset. Just this week, the UK's Health and Safety Executive said that the government is on course to complete the Generic Design Assessment of the EPR reactor and the AP1000 reactor from Westinghouse by the June 2011 deadline. However, he also admitted that the government has also has experienced "significant delays" in receiving responses to technical queries regarding the reactors, neither of which are fully complete.

EDF announced last December that the cost of installing the second EPR reactor at the Flamanville 3 Nuclear Power Station in France had leapt from the original $4 billion budget to $5.6 billion.

In North Carolina, unpaid electric and water bills are driving families and cities to the financial brink

North Carolina Utility Arrears Crisis strains households and municipal budgets as COVID-19 cuts jobs; unpaid utility bills mount, shutoffs loom, and emergency aid, unemployment benefits, and CARES Act relief lag behind rising arrears across cities.

 

Key Points

A COVID-19 driven spike in unpaid utility bills, threatening households and municipal budgets as federal aid lapses.

✅ 1 million families behind on power, water, sewage bills

✅ $218M arrears accrued April to June, double last year

✅ Municipal utilities face shutoffs, budget shortfalls

 

As many as 1 million families in North Carolina have fallen behind on their electric, water and sewage bills, a sign of energy insecurity threatening residents and their cities with severe financial hardship unless federal lawmakers act to approve more emergency aid.

The trouble stems from the widespread economic havoc wrought by the coronavirus, which has left millions of workers out of a job and struggling to cover their monthly costs as some states moved to suspend utility shut-offs to provide relief. Together, they’ve been late or missed a total of $218 million in utility payments between April 1 and the end of June, according to data released recently by the state, nearly double the amount in arrears at this time last year.

In some cases, cities that own or operate their own utilities have been forced to absorb these losses, as some utilities reconnected customers to prevent harm, creating a dire situation in which the government’s attempt to save people from the financial brink instead has pushed municipal coffers to their own breaking point.

In Elizabeth City, N.C., for example, about 2,500 residents haven’t paid their electric bills on time, according to Richard Olson, the city manager. The late payments at one point proved so problematic that Olson said he calculated Elizabeth City wouldn’t have enough money to pay for its expenses in July. In response, city leaders requested and obtained a waiver from a statewide order, similar to New York’s disconnection moratorium, issued in March, that protects people from being penalized for their past-due utility bills.

The predicament has presented unique budget challenges throughout North Carolina, while illustrating the consequences of a cash crunch plaguing the entire country, where proposals such as a Texas electricity market bailout surfaced following severe grid stress. State and federal leaders have extended a range of coronavirus relief programs since March to try to help people through the pandemic. But the money is limited and restricted — and it’s not clear whether more help from Congress is on the way — creating a crisis in which the nation’s economic woes are outpacing some of the aid programs adopted to combat them.

“We are entering a phase where the utilities [may] be able to shut off power, but what was propping up people’s economic lives, the unemployment benefits and Cares Act support, won’t be there,” said Paul Meyer, the executive director of the North Carolina League of Municipalities.

White House, GOP in disarray over coronavirus spending plan as deadline nears on expiring emergency aid

The future of that safety-net support — and other federal aid — hangs in the balance as lawmakers returned to work this week in their final sprint ahead of the August recess. The White House and congressional leaders are split over the contours of the next coronavirus relief package, including the need to extend more aid to cities and states as some utilities have waived fees to help customers, and reauthorize an extra $600 in weekly unemployment payments that were approved as part of the Cares Act in March.

Outside Washington, workers, businesses and government officials nationwide have pleaded with federal lawmakers to renew or expand those programs. Last week, Roy Cooper, the Democratic governor of North Carolina, urged Congress to act swiftly and adopt a wide array of new federal spending, including proposals for DOE nuclear cleanup funding, stressing in a letter that the “actions you take in the next few weeks are vital to our ability to emerge from this crisis. ”

Two new BC generating stations officially commissioned

BC Hydro Site C and Clean Energy Policy shapes B.C.'s power mix, affecting run-of-river hydro, net metering for rooftop solar, independent power producers, and surplus capacity forecasts tied to LNG Canada demand.

 

Key Points

BC Hydro's strategy centers on Site C, limiting new run-of-river projects and tightening net metering amid surplus power

✅ Site C adds long-term capacity with lower projected rates.

✅ Run-of-river IPP growth paused amid surplus forecasts.

✅ Net metering limits deter oversized rooftop solar.

 

Innergex Renewable Energy Inc. is celebrating the official commissioning today of what may be the last large run-of-river hydro project in B.C. for years to come.

The project – two new generating stations on the Upper Lillooet River and Boulder Creek in the Pemberton Valley – actually began producing power in 2017, but the official commissioning was delayed until Friday September 14.

Innergex, which earlier this year bought out Vancouver’s Alterra Power, invested $491 million in the two run-of-river hydro-electric projects, which have a generating capacity of 106 megawatts of power. The project has the generating capacity to power 39,000 homes.

The commissioning happened to coincide with an address by BC Hydro CEO Chris O’Riley to the Greater Vancouver Board of Trade Friday, in which he provided an update on the progress of the $10.7-billion Site C dam project.

That project has put an end, for the foreseeable future, of any major new run-of-river projects like the Innergex project in Pemberton.

BC Hydro expects the new dam to produce a surplus of power when it is commissioned in November 2024, so no new clean energy power calls are expected for years to come.

Independent power producers aren’t the only ones who have seen a decline in opportunities to make money in B.C. providing renewable power, as the Siwash Creek project shows. So will homeowners who over-build their own solar power systems, in an attempt to make money from power sales.

There are about 1,300 homeowners in B.C. with rooftop solar systems, and when they produce surplus power, they can sell it to BC Hydro.

BC Hydro is amending the net metering program to discourage homeowners from over-building. In some cases, some howeowners have been generating 40% to 50% more power than they need.

“We were getting installations that were massively over-sized for their load, and selling this big quantity of power to us,” O’Riley said. “And that was never the idea of the program.”

Going forward, BC Hydro plans to place limits on how much power a homeowner can sell to BC Hydro.

BC Hydro has been criticized for building Site C when the demand for power has been generally flat, and reliance on out-of-province electricity has drawn scrutiny. But O’Riley said the dam isn’t being built for today’s generation, but the next.

“We’re not building Site C for today,” he said. “We have an energy surplus for the short term. We’re not even building it for 2024. We’re building it for the next 100 years.”

O’Riley acknowledged Site C dam has been a contentious and “extremely challenging” project. It has faced numerous court challenges, a late-stage review by the BC Utilities Commission, cost overruns, geotechnical problems and a dispute with the main contractors.

In a separate case, the province was ordered to pay $10 million over the denial of a Squamish power project, highlighting broader legal risk.

But those issues have been resolved, O’Riley said, and the project is back on track with a new construction schedule.

“As we move forward, we have a responsibility to deliver a project on time and against the new revised budget, and I’m confident the changes we’ve made are set up to do that,” O’Riley said.

Currently, there are about 3,300 workers employed on the dam project.

Despite criticisms that BC Hydro is investing in a legacy mega-project at a time when cost of wind and solar have been falling, O’Riley insisted that Site C was the best and lowest cost option.

“First, it’s the lowest cost option,” he said. “We expect over the first 20 years of Site C’s operating life, our customers will see rates 7% to 10% below what it would otherwise be using the alternatives.”

BC Hydro missed a critical window to divert the Peace River, something that can only be done in September, during lower river flows. That added a full year’s delay to the project.

O’Riley said BC Hydro had built in a one-year contingency into the project, so he expects the project can still be completed by 2024 – the original in-service target date. But the delay will add more than $2 billion to the last budget estimate, boosting the estimated capital cost from $8.3 billion to $10.7 billion.

Meeting the 2024 in-service target date could be important, if Royal Dutch Shell and its consortium partners make a final investment decision this year on the $40 billion LNG Canada project.

That project also has a completion target date of 2024, and would be a major new industrial customer with a substantial power draw for operations.

“If they make a decision to go forward, they will be a very big customer of BC Hydro,” O’Riley told Business in Vancouver. “They would be in our top three or four biggest customers.”

The nuclear power dispute driving a wedge between France and Germany

Franco-German Nuclear Power Divide shapes EU energy policy, electricity market reform, and decarbonization strategies, as Paris backs reactors and state subsidies while Berlin prioritizes renewables, hydrogen, and energy security after Russian gas shocks.

 

Key Points

A policy rift over nuclear shaping EU market reform, subsidies, and the balance between reactors and renewables.

✅ Nuclear in EU targets vs. renewables-first strategy

✅ Market design disputes over long-term power prices

✅ Energy security after Russian gas; hydrogen definitions

 

Near the French village of Fessenheim, facing Germany across the Rhine, a nuclear power station stands dormant. The German protesters that once demanded the site’s closure have decamped, in a sign of Europe's nuclear decline, and the last watts were produced three years ago. 

But disagreements over how the plant from 1977 should be repurposed persist, speaking to a much deeper divide over nuclear power, which Eon chief's warning to Germany underscored, between the two countries on either side of the river’s banks.

German officials have disputed a proposal to turn it into a centre to treat metals exposed to low levels of radioactivity, Fessenheim’s mayor Claude Brender says. “They are not on board with anything that might in some way make the nuclear industry more acceptable,” he adds.

France and Germany’s split over nuclear power is a tale of diverging mindsets fashioned over decades, including since the Chernobyl disaster in USSR-era Ukraine. But it has now become a major faultline in a touchy relationship between Europe’s two biggest economies.

Their stand-off over how to treat nuclear in a series of EU reforms has consequences for how Europe plans to advance towards cleaner energy. It will also affect how the bloc secures power supplies as the region weans itself off Russian gas, even though nuclear would do little for the gas issue, and how it provides its industry with affordable energy to compete with the US and China. 

“There can be squabbles between partners. But we’re not in a retirement home today squabbling over trivial matters. Europe is in a serious situation,” says Eric-André Martin, a specialist in Franco-German relations at French think-tank IFRI. 

France, which produces two-thirds of its power from nuclear plants and has plans for more reactors, is fighting for the low-carbon technology to be factored into its targets for reducing emissions and for leeway to use state subsidies to fund the sector.

For Germany, which closed its last nuclear plants this year and, having turned its back on nuclear, has been particularly shaken by its former reliance on Russian gas, there’s concern that a nuclear drive will detract from renewable energy advances.

But there is also an economic subtext in a region still reeling from an energy crisis last year, reviving arguments for a needed nuclear option for climate in Germany, when prices spiked and laid bare how vulnerable households and manufacturers could become.

Berlin is wary that Paris would benefit more than its neighbours if it ends up being able to guarantee low power prices from its large nuclear output as a result of new EU rules on electricity markets, amid talk of a possible U-turn on the phaseout, people close to talks between the two countries say.

Ministers on both sides have acknowledged there is a problem. “The conflict is painful. It’s painful for the two governments as well as for our [EU] partners,” Sven Giegold, state secretary at the German economy and climate action ministry, where debates about whether a nuclear resurgence is possible persist, tells the Financial Times. 

Agnès Pannier-Runacher, France’s energy minister, says she wants to “get out of the realm of the emotional and move past the considerable misunderstandings that have accumulated in this discussion”.

In a joint appearance in Hamburg last week, German chancellor Olaf Scholz and French president Emmanuel Macron made encouraging noises over their ability to break the latest deadlock: a disagreement over the design of the EU’s electricity market. Ministers had been due to agree a plan in June but will now meet on October 17 to discuss the reform, aimed at stabilising long-term prices.

But the French and German impasse on nuclear has already slowed down debates on key EU policies such as rules on renewable energy and how hydrogen should be produced. Smaller member states are becoming impatient. The delay on the market design is “a big Franco-German show of incompetence again”, says an energy ministry official from another EU country who requested anonymity.

Fixing California's electric grid is like repairing a car while driving

CAISO Clean Energy Transition outlines California's path to 100% carbon-free power by 2045, scaling renewables, battery storage, and offshore wind while safeguarding grid reliability, managing natural gas, and leveraging Western markets like EDAM.

 

Key Points

CAISO Clean Energy Transition is the plan to reach 100% carbon-free power by 2045 while maintaining grid reliability.

✅ Target: add 7 GW/year to reach 120 GW capacity by 2045

✅ Battery storage up 30x; smooths intermittent solar and wind

✅ EDAM and WEIM enhance imports, savings, and reliability

 

Mark Rothleder, Chief Operating Officer and Senior Vice President at the California Independent System Operator (CAISO), which manages roughly 80% of California’s electric grid, has expressed cautious optimism about meeting the state's ambitious clean energy targets while keeping the lights on across the grid. However, he acknowledges that this journey will not be without its challenges.

California aims to transition its power system to 100% carbon-free sources by 2045, ensuring a reliable electricity supply at reasonable costs for consumers. Rothleder, aware of the task's enormity, likens it to a complex car repair performed while the vehicle is in motion.

Recent achievements have demonstrated California's ability to temporarily sustain its grid using clean energy sources. According to Rothleder, the real challenge lies in maintaining this performance round the clock, every day of the year.

Adding thousands of megawatts of renewable energy into California’s existing 50-gigawatt system, which needs to expand to 120 gigawatts to meet the 2045 goal, poses a significant challenge, though recent grid upgrade funding offers some support for needed infrastructure. CAISO estimates that an addition of 7 gigawatts of clean power per year for the next two decades is necessary, all while ensuring uninterrupted power delivery.

While natural gas currently constitutes California's largest single source of power, Rothleder notes the need to gradually decrease reliance on it, even as it remains an operational necessity in the transition phase.

In 2023, CAISO added 5,660 megawatts of new power to the grid, with plans to integrate over 1,100 additional megawatts in the next six to eight months of 2024. Battery storage, crucial for mitigating the intermittent nature of wind and solar power, has seen substantial growth as California turns to batteries for grid support, increasing 30-fold in three years.

Rothleder emphasizes that electricity reliability is paramount, as consumers always expect power availability. He also highlights the potential of offshore wind projects to significantly contribute to California's power mix by 2045.

The offshore wind industry faces financial and supply chain challenges despite these plans. CAISO’s 20-year outlook indicates a significant increase in utility-scale solar, requiring extensive land use and wider deployment of advanced inverters for grid stability.

Addressing affordability is vital, especially as California residents face increasing utility bills. Rothleder suggests a broader energy cost perspective, encompassing utility and transportation expenses.

Despite smooth grid operations in 2023, challenges in previous years, including extreme weather-induced power outages driven by climate change, underscore the need for a robust, adaptable grid. California imports about a quarter of its power from neighbouring states and participates in the Western Energy Imbalance Market, which has yielded significant savings.

CAISO is also working on establishing an extended day-ahead electricity market (EDAM) to enhance the current energy market's success, building on insights from a Western grid integration report that supports expanded coordination.

Rothleder believes that a thoughtfully designed, diverse power system can offer greater reliability and resilience in the long run. A future grid reliant on multiple, smaller power sources such as microgrids could better absorb potential losses, ensuring a more reliable electricity supply for California.

BC residents split on going nuclear for electricity generation: survey

BC Energy Debate: Nuclear Power and LNG divides British Columbia, as a new survey weighs zero-emission clean energy, hydroelectric capacity, the Site C dam, EV mandates, energy security, rising costs, and blackout risks.

 

Key Points

A BC-wide debate on power choices balancing nuclear, LNG, hydro, costs, climate goals, EVs, and grid reliability.

✅ Survey: 43% support nuclear, 40% oppose in BC

✅ 55% back LNG expansion, led by Southern BC

✅ Hydro at 90%; Site C adds 1,100 MW by 2025

 

There is a long-term need to produce more electricity to meet population and economic growth needs and, in particular, create new clean energy sources, with two new BC generating stations recently commissioned contributing to capacity.

Increasingly, in the worldwide discourse on climate change, nuclear power plants are being touted as a zero-emission clean energy source, with Ontario exploring large-scale nuclear to expand capacity, and a key solution towards meeting reduced emissions goals. New technological advancements could make nuclear power far safer than existing plant designs.

When queried on whether British Columbia should support nuclear power for electricity generation, respondents in a new province-wide survey by Research Co. were split, with 43% in favour and 40% against.

Levels of support reached 46% in Metro Vancouver, 41% in the Fraser Valley, 44% in Southern BC, 39% in Northern BC, and 36% on Vancouver Island.

The closest nuclear power plant to BC is the Columbia Generating Station, located in southern Washington State.

The safe use of nuclear power came to the forefront following the 2011 Fukushima nuclear disaster when the most powerful earthquake ever recorded in Japan triggered a large tsunami that damaged the plant’s emergency generators. Japan subsequently shut off many of its nuclear power plants and increased its reliance on fossil fuel imports, but in recent years there has been a policy reversal to restart shuttered nuclear plants to provide the nation with improved energy security.

Over the past decade, Germany has also been undergoing a transition away from nuclear power. But in an effort to replace Russian natural gas, Germany is now using more coal for power generation than ever before in decades, while Ontario’s electricity outlook suggests a shift to a dirtier mix, and it is looking to expand its use of liquefied natural gas (LNG).

Last summer, German chancellor Olaf Scholz told the CBC he wants Canada to increase its shipments of LNG gas to Europe. LNG, which is greener compared to coal and oil, is generally seen as a transitionary fuel source for parts of the world that currently depend on heavy polluting fuels for power generation.

When the Research Co. survey asked BC residents whether they support the further development of the province’s LNG industry, including LNG electricity demand that BC Hydro says justifies Site C, 55% of respondents were supportive, while 29% were opposed and 17% undecided.

Support for the expansion of the LNG is highest in Southern BC (67%), followed by the Fraser Valley (56%), Metro Vancouver (also 56%), Northern BC (55%), and Vancouver Island (41%).

A larger proportion of BC residents are against any idea of the provincial government moving to ban the use of natural gas for stoves and heating in new buildings, with 45% opposed and 39% in support.

Significant majorities of BC residents are concerned that energy costs could become too expensive, and a report on coal phase-outs underscores potential cost and effectiveness concerns, with 84% expressing concern for residents and 66% for businesses. As well, 70% are concerned that energy shortages could lead to measures such as rationing and rolling blackouts.

Currently, about 90% of BC’s electricity is produced by hydroelectric dams, but this fluctuates throughout the year — at times, BC imports coal- and gas-generated power from the United States when hydro output is low.

According to BC Hydro’s five-year electrification plan released in September 2021, it is estimated BC has a sufficient supply of clean electricity only by 2030, including the capacity of the Site C dam, which is slated to open in 2025. The $16 billion dam will have an output capacity of 1,100 megawatts or enough power for the equivalent of 450,000 homes.

The provincial government’s strategy for pushing vehicles towards becoming dependent on the electrical grid also necessitates a reliable supply of power, prompting BC Hydro’s first call for power in 15 years to prepare for electrification. Most BC residents support the provincial government’s requirement for all new car and passenger truck sales to be zero-emission by 2035, with 75% supporting the goal and 21% opposed.

End of an Era: UK's Last Coal Power Station Goes Offline

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

 

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

 

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.


A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.


Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.


Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.


Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.


Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.


The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.
