Canada's atomic safety agency has raised concerns over the "erosion of safety margins" at the Pickering B nuclear power station, prompting Greenpeace to repeat calls for the plant to be closed.

The Canadian Nuclear Safety Commission says safety margins at the aging plant on the eastern fringe of the GTA – an area home to 5 million people – are no longer as "robust" as they should be.

Safety margins set out acceptable risk at nuclear plants and determine what systems must be in place in the event of an accident. Older plants must review and upgrade them to keep pace with current standards in the industry.

The warning was sent to Pickering owner Ontario Power Generation (OPG) in a letter April 7 as it seeks approval to keep the plant open until 2014 to meet the province's electricity needs. Safety commission staff "remain concerned with the trend in erosion of safety margins," said the lengthy and highly technical letter to Patrick McNeil, OPG's senior vice-president.

Despite the concern, staff at the safety commission has recommended a five-year operating licence renewal for Pickering B, said OPG spokesperson John Earl.

"Neither the regulator nor OPG would allow the plant to operate if it wasn't safe," he told the Star.

The commission said it expects "that OPG will address the identified outstanding issues, and, in particular, will develop and implement engineered solutions to re-establish robust safety margins."

The letter was obtained by Greenpeace, which will appear at a hearing in Ajax today to argue against OPG's request for a five-year operating licence renewal at Pickering B, built in the mid-1980s.

"They're discovering at Pickering B that it's worse than they thought," said Shawn Patrick Stensil, energy campaigner for Greenpeace.

"Pickering is closer to a major population centre than any other nuclear reactor in the world.

Officials at OPG sought to play down the letter from the nuclear safety commission as one in a long series of correspondence as the government-owned utility seeks the licence renewal. McNeil has gone on record saying that there is less than a "one in a million" chance for a problem.

"The safety margin is completely adequate to meet the needs of the plant."

Stensil said he does not take comfort from the fact that the commission is recommending a renewal, given the politics swirling around nuclear energy.

"On the one occasion that former (safety commission) president Linda Keen stood up to the nuclear industry she was fired by the Harper government," he noted, referring to the commission's safety concerns that resulted in the temporary closing of a nuclear reactor in Chalk River that produced materials for nuclear medicine.

Stensil called the firing "a frightening lesson in an industry where safety is paramount. It's very unlikely that the regulator will have the courage to stand up to the industry again."

There is another layer of politics in Ontario. Atomic Energy of Canada, a Crown corporation that designed the CANDU reactors at Pickering, is one of several companies seeking a contract to build more nuclear power reactors in the province. The province's decision on that is due by early next year.

US nuclear innovation act becomes law

NEIMA advances NRC regulatory modernization, creating a licensing framework for advanced reactors, improving uranium permitting, capping reactor fees, and mandating DOE planning for excess uranium, boosting transparency, accountability, and innovation across the US nuclear sector.

 

Key Points

NEIMA is a US law modernizing NRC rules and enabling advanced reactor licensing while reforming fees.

✅ Modernizes NRC licensing for advanced reactors

✅ Caps annual reactor fees and boosts transparency

✅ Streamlines uranium permitting; directs DOE plans

 

Bipartisan legislation modernising US nuclear regulation and supporting the establishment of a licensing framework for next-generation advanced reactors has been signed by US President Donald Trump, whose order boosting U.S. uranium and nuclear energy underscored the administration's focus on the sector.

The Nuclear Energy Innovation and Modernisation Act (NEIMA) became law on 14 January.

As well as directing the Nuclear Regulatory Commission (NRC) to modify the licensing process for commercial advanced nuclear reactor facilities, the bill establishes new transparency and accountability measures to the regulator's budget and fee programmes, and caps fees for existing reactors. It also directs the NRC to look at ways of improving the efficiency of uranium licensing, including investigating the safety and feasibility of extending uranium recovery licences from ten to 20 years' duration, and directs the Department of Energy, which oversees nuclear cleanup and related projects, to issue at least every ten years a long-term plan detailing the management of its excess uranium inventories.

Maria Korsnick, president and CEO of the US Nuclear Energy Institute, described NEIMA as a "significant, positive step" toward the reform of the NRC's fee collection process. "This legislation establishes a more equitable and transparent funding structure which will benefit all operating reactors and future licensees," she said. "The bill also reaffirms Congress’s support for nuclear innovation by working to establish an efficient and stable regulatory structure that is prepared to license the advanced reactors of the future."

Marilyn Kray, president-elect of the American Nuclear Society, said the passage of the legislation was a "big win" for the nation and its nuclear community. "By reforming outdated laws, NRC will now be able to invest more freely in advanced nuclear R&D and licensing activities. This in turn will accelerate deployment of cutting-edge American nuclear systems and better prepare the next generation of nuclear engineers and technologists," she said.

The bill was introduced in 2017 by Senator John Barrasso of Wyoming. It was approved by Congress on 21 December by 361 votes to 10, having been passed by the Senate the previous day, even as later Biden's climate law developments produced mixed results.

NEIMA is one of several bipartisan bills that support advanced nuclear innovation considered by the 115th US Congress, which ended on 2 January. These are: the Nuclear Energy Innovation Capabilities Act (NEICA); the Nuclear Energy Leadership Act; the Nuclear Utilisation of Keynote Energy Act; the Advanced Nuclear Fuel Availability Act, a focus sharpened by the U.S. ban on Russian uranium in the fuel market; and legislation to expedite so-called part 810 approvals, which are needed for the export of technology, equipment and components. NEICA, which supports the deployment of advanced reactors and also directs the DOE to develop a reactor-based fast neutron source for the testing of advanced reactor fuels and materials, was signed into law in October.

Ontario’s Electricity Future: Balancing Demand and Emissions 

Ontario Electricity Transition faces surging demand, GHG targets, and federal regulations, balancing natural gas, renewables, battery storage, and grid reliability while pursuing net-zero by 2035 and cost-effective decarbonization for industry, EVs, and growing populations.

 

Key Points

Ontario Electricity Transition is the province's shift to a reliable, low-GHG grid via renewables, storage, and policy.

✅ Demand up 75% by 2050; procurement adds 4,000 MW capacity.

✅ Gas use rises to 25% by 2030, challenging GHG goals.

✅ Tripling wind and solar with storage can cut costs and emissions.

 

Ontario's electricity sector stands at a pivotal crossroads. Once a leader in clean energy, the province now faces the dual challenge of meeting surging demand while adhering to stringent greenhouse gas (GHG) reduction targets. Recent developments, including the expansion of natural gas infrastructure and proposed federal regulations, have intensified debates about the future of Ontario's energy landscape, as this analysis explains in detail.

Rising Demand and the Need for Expansion

Ontario's electricity demand is projected to increase by 75% by 2050, equivalent to adding four and a half cities the size of Toronto to the grid. This surge is driven by factors such as industrial electrification, population growth, and the transition to electric vehicles. In response, as Ontario confronts a looming shortfall in the coming years, the provincial government has initiated its most ambitious energy procurement plan to date, aiming to secure an additional 4,000 megawatts of capacity by 2030. This includes investments in battery storage and natural gas generation to ensure grid reliability during peak demand periods.

The Role of Natural Gas: A Controversial Bridge

Natural gas has become a cornerstone of Ontario's strategy to meet immediate energy needs. However, this reliance comes with environmental costs. The Independent Electricity System Operator (IESO) projects that by 2030, natural gas will account for 25% of Ontario's electricity supply, up from 4% in 2017. This shift raises concerns about the province's ability to meet its GHG reduction targets and to embrace clean power in practice. 

The expansion of gas-fired plants, including broader plans for new gas capacity, such as the Portlands Energy Centre in Toronto, has sparked public outcry. Environmental groups argue that these expansions could undermine local emissions reduction goals and exacerbate health issues related to air quality. For instance, emissions from the Portlands plant have surged from 188,000 tonnes in 2017 to over 600,000 tonnes in 2021, with projections indicating a potential increase to 1.65 million tonnes if the expansion proceeds as planned. 

Federal Regulations and Economic Implications

The federal government's proposed clean electricity regulations aim to achieve a net-zero electricity sector by 2035. However, Ontario's government has expressed concerns that these regulations could impose significant financial burdens. An analysis by the IESO suggests that complying with the new rules would require doubling the province's electricity generation capacity, potentially adding $35 billion in costs by 2050, while other estimates suggest that greening Ontario's grid could cost $400 billion over time. This could result in higher residential electricity bills, ranging from $132 to $168 annually starting in 2033.

Pathways to a Sustainable Future

Experts advocate for a diversified approach to decarbonization that balances environmental goals with economic feasibility. Investments in renewable energy sources, such as new wind and solar resources, along with advancements in energy storage technologies, are seen as critical components of a sustainable energy strategy. Additionally, implementing energy efficiency measures and modernizing grid infrastructure can enhance system resilience and reduce emissions. 

The Ontario Clean Air Alliance proposes phasing out gas power by 2035 through a combination of tripling wind and solar capacity and investing in energy efficiency and storage solutions. This approach not only aims to reduce emissions but also offers potential cost savings compared to continued reliance on gas-fired generation. 

Ontario's journey toward a decarbonized electricity grid is fraught with challenges, including balancing reliability, clean, affordable electricity, and environmental sustainability. While natural gas currently plays a significant role in meeting the province's energy needs, its long-term viability as a bridge fuel remains contentious. The path forward will require careful consideration of technological innovations, regulatory frameworks, and public engagement to ensure a clean, reliable, and economically viable energy future for all Ontarians.

Norway Considers Curbing Electricity Exports to Avoid Shortages

Norway Electricity Export Limits weigh hydro reservoirs, energy security, EU-UK interconnectors, and record power prices amid Russia gas cuts; Statnett grid constraints and subsidies debate intensify as reservoir levels fall, threatening winter supply.

 

Key Points

Rules to curb Norway's power exports when reservoirs are very low, protecting supply security and easing extreme prices.

✅ Triggered by low hydro levels and record day-ahead prices

✅ Considers EU/UK cables, Statnett operations, seasonal thresholds

✅ Aims to secure winter supply and expand subsidies

 

Norway, one of Europe’s biggest electricity exporters, is considering measures to limit power shipments to prevent domestic shortages amid surging prices, according to local media reports.

The government may propose a rule to limit exports if the water level for Norway’s hydro reservoirs drops to “very low” levels, to ensure security of supply, said Energy Minister Terje Aasland, according NTB newswire. The limit would take account of seasonality and would differ across the about 1,800 hydro reservoirs, he said. 

Russia’s gas supply cuts in retaliation for European sanctions over the war in Ukraine have triggered the continent’s worst energy crisis in decades, with demand surging for cheap Norwegian hydro electricity. Yet the government faces increasing calls from the public and opposition to limit flows abroad. Prices are near record levels in some parts of the Nordic nation as hydro-reservoir levels have plunged in the south after a drier-than-normal spring. 

The government has been under pressure to do something about exports since before April. Flows on the cables are regulated by deals with both the European Union and the UK energy market and Norway can’t simply cut flows. It’s the latest test of European solidarity and a wake-up call for Europe when it comes to energy supplies. Hungary is trying to ban energy exports after it declared an energy emergency.

Back in May, grid operator Statnett SF warned that Norway could face a strained power situation after less snowfall than usual during the winter. At the end of last week, the level of filling in Norwegian hydro reservoirs was 66.5%, compared with a median 74.9% for the corresponding time in 2002-2021, regulator NVE said. Day-ahead electricity prices in southwest Norway soared to a record 423 euros per megawatt-hour late last month, partly due to bottlenecks in the grid limiting supply from the northern regions.

The grid operator has been asked to present by Oct. 1 possible measures that need to be taken to secure supply and infrastructure security ahead of the winter. Statnett operates cables to the UK and Germany aimed at selling surplus electricity and would likely take a financial hit if curbs were introduced. “Operations of these will always follow current laws and regulations,” Irene Meldal, a company spokeswoman, said Friday by email. 

Premier Jonas Gahr Store signaled his minority government will file proposals that also include more subsidies to families and companies and align with Europe’s emergency price measures during August, according to an interview with TV2 on Thursday. Meanwhile, opposition politicians plan to hold an extraordinary parliament meeting to discuss boosting the subsidies.

Aasland will summon the parties’ representatives to a meeting on Monday on the electricity crisis, the Aftenposten newspaper reported on Friday, without citing anyone. He intends to inform the parties about the ongoing work and aims to “avoid rushed decisions” by the parliamentary majority.

Norway Faces Pressure to Curb Power Exports as Prices Surge (1)

The nation gets almost all of its electricity from its vast hydro resources. Historically, it has been able to export a hefty surplus and still have among the lowest prices in Europe.

Extreme Heat Boosts U.S. Electricity Bills

Extreme Heat and Rising Electricity Bills amplify energy costs as climate change drives air conditioning demand, stressing the power grid and energy affordability, with low income households facing outsized burdens during prolonged heat waves.

 

Key Points

Heat waves from climate change raise AC demand, driving up electricity costs and straining energy affordability.

✅ More AC use spikes electricity demand during heat waves

✅ Low income households face higher energy burden

✅ Grid reliability risks rise with peak cooling loads

 

Extreme heat waves are not only straining public health systems but also having a significant impact on household finances, particularly through rising electricity bills. According to a recent AP-NORC poll, a growing number of Americans are feeling the financial pinch as soaring temperatures drive up the cost of cooling their homes. This development underscores the broader implications of climate change and its effects on everyday life.

The AP-NORC poll highlights that a majority of Americans are experiencing increased electricity costs as a direct result of extreme heat. As temperatures climb, so does the demand for air conditioning and other cooling systems. This increased energy consumption is contributing to higher utility bills, which can put additional strain on household budgets.

Extreme heat waves have become more frequent and intense due to climate change, which has led to a greater reliance on air conditioning to maintain comfortable indoor environments. Air conditioners and fans work harder during heat waves, and wasteful air conditioning can add around $200 to summer bills, consuming more electricity and consequently driving up energy bills. For many households, particularly those with lower incomes, these increased costs can be a significant burden.

The poll reveals that the impact of rising electricity bills is widespread, affecting a diverse range of Americans. Households across different income levels and geographic regions are feeling the heat, though the extent of the financial strain can vary. Lower-income households are particularly vulnerable, as they often have less flexibility in their budgets to absorb higher utility costs. For these families, the choice between cooling their homes and other essential expenses can be a difficult one.

In addition to financial strain, the poll highlights concerns about energy affordability and access. As electricity bills rise, some Americans may face challenges in paying their bills, leading to potential utility shut-offs or the need to make difficult choices between cooling and other necessities. This situation is exacerbated by the fact that many utility companies do not offer sufficient assistance or relief programs to help low-income households manage their energy costs.

The increasing frequency of extreme heat events and the resulting spike in electricity consumption also have broader implications for the energy infrastructure. Higher demand for electricity can strain power grids, as seen when California narrowly avoided blackouts during extreme heat, potentially leading to outages or reduced reliability. Utilities and energy providers may need to invest in infrastructure upgrades and maintenance to ensure that the grid can handle the increased load during heat waves.

Climate change is a key driver of the rising temperatures that contribute to higher electricity bills. As global temperatures continue to rise, extreme heat events are expected to become more common and severe, and experts warn the US electric grid was not designed to withstand these impacts. This trend underscores the need for comprehensive strategies to address both the causes and consequences of climate change. Efforts to reduce greenhouse gas emissions, improve energy efficiency, and invest in renewable energy sources are critical components of a broader climate action plan.

Energy efficiency measures can play a significant role in mitigating the impact of extreme heat on electricity bills. Upgrading to more efficient cooling systems, improving home insulation, and adopting smart thermostats can help reduce energy consumption and lower utility costs. Additionally, utility companies and government programs can offer incentives and rebates, including ways to tap new funding that help encourage energy-saving practices and support households in managing their energy use.

The poll also suggests that there is a growing awareness among Americans about the connection between climate change and rising energy costs. Many people are becoming more informed about the ways in which extreme weather events and rising temperatures impact their daily lives. This increased awareness can drive demand for policy changes and support for initiatives aimed at addressing climate change and improving energy efficiency, with many willing to contribute income to climate efforts, about the connection between climate change and rising energy costs.

In response to the rising costs and the impact of extreme heat, there are calls for policy interventions and support programs to help manage energy affordability. Proposals include expanding assistance programs for low-income households, investing in infrastructure improvements, and promoting energy efficiency initiatives alongside steps to make electricity systems more resilient to climate risks. By addressing these issues, policymakers can help alleviate the financial burden on households and support a more resilient and sustainable energy system.

Debates over policy impacts on electricity prices continue; in Alberta, federal policies are blamed by some for higher rates, illustrating how regulation can affect affordability.

In conclusion, the AP-NORC poll highlights the growing financial impact of extreme heat on American households, with rising electricity bills being a significant concern for many. The increased demand for cooling during heat waves is straining household budgets and raising broader questions about energy affordability and infrastructure resilience. Addressing these challenges requires a multifaceted approach, including efforts to combat climate change, improve energy efficiency, and provide support for those most affected by rising energy costs. As extreme heat events become more common, finding solutions to manage their impact will be crucial for both individual households and the broader energy system.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.

Coronavirus impacts dismantling of Germany's Philippsburg nuclear plant

Philippsburg Demolition Delay: EnBW postpones controlled cooling-tower blasts amid the coronavirus pandemic, affecting decommissioning timelines in Baden-Wurttemberg and grid expansion for a transformer station to route renewable power and secure supply in southern Germany.

 

Key Points

EnBW's COVID-19 delay of Philippsburg cooling-tower blasts, affecting decommissioning and grid plans.

✅ Controlled detonation shifted to mid-May at earliest

✅ Demolition links to transformer station for north-south grid

✅ Supports security of supply in southern Germany

 

German energy company EnBW said the coronavirus outbreak has impacted plans to dismantle its Philippsburg nuclear power plant in Baden-Wurttemberg, southwest Germany, amid plans to phase out coal and nuclear nationally.

The controlled detonation of Phillipsburg's cooling towers will now take place in mid-May at the earliest, subject to coordination as Germany debates whether to reconsider its nuclear phaseout in light of supply needs.

However, EnBW said the exact demolition date depends on many factors - including the further development in the coronavirus pandemic and ongoing climate policy debates about energy choices.

Philippsburg 2, a 1402MWe pressurised water reactor unit permanently shut down on 31 December 2019, as part of Germany's broader effort to shut down its remaining reactors over time.

At the end of 2019, the Ministry of the Environment gave basic approval for decommissioning and dismantling of unit 2 of the Philippsburg nuclear power plant, inluding explosive demolition of the colling towers. Since then EnBW has worked intensively on getting all the necessary formal steps on the way and performing technical and logistical preparatory work, even as discussions about a potential nuclear resurgence continue nationwide.

“The demolition of the cooling towers is directly related to future security of supply in southern Germany. We therefore feel obliged to drive this project forward," said Jörg Michels head of the EnBW nuclear power division.

The timely removal of the cooling towers is important as the area currently occupied by nuclear plant components is needed for a transformer station for long-distance power lines, an issue underscored during the energy crisis when Germany temporarily extended nuclear power to bolster supply. These will transport electricity from renewable sources in the north to industrial centres in the south.

As of early 2020, there six nuclear reactors in operation in Germany, even as the country turned its back on nuclear in subsequent years. According to research institute Fraunhofer ISE, nuclear power provided about 14% of Germany's net electricity in 2019, less than half of the figure for 2000.
