The federal nuclear safety watchdog says more than 200 workers may have been exposed to a dangerous form of radioactivity while they were refurbishing a reactor at the Bruce power station late last year.

The Canadian Nuclear Safety Commission filed a regulatory document in Ottawa saying up to 217 workers at the plant on the shores of Lake Huron may have inhaled potentially hazardous "alpha contamination."

A routine survey picked up contamination in the air in Bruce A station's Unit 1 on November 26, 2009, the document says.

The radioactive particles are linked to cancer if ingested, inhaled or absorbed through cuts in the skin.

But Bruce Power says monitoring of potentially affected workers indicates the levels of exposure were within limits set under federal rules.

"All our analysis from our preliminary readings is that regulatory levels have not even been approached and half the ones we've received were too low even to register," said spokesman John Peevers.

The 217 workers are staff at Bruce or outside contractors working on the lengthy refurbishment project. Testing of their radiation levels continues.

"Preliminary monitoring of all potentially affected workers indicated no overexposures," the nuclear safety commission said on its website.

Bruce Power also said contamination was fully contained in the affected unit and there is no risk to the public or surrounding environment.

Work in the affected vault in Unit 1 was stopped until cleanup of the contamination was complete, and monitors have been installed to identify any further contamination, the document says.

The nuclear safety commission, which was first notified of the incident orally on January 5 and received a written report two days later, plans to discuss the incident at its public board meeting.

By Land and Sea, Clean Electricity Needs to Lead the Way

Martha's Vineyard 100% Renewable Energy advances electrification across EVs, heat pumps, distributed solar, offshore wind, microgrids, and battery storage, cutting emissions, boosting efficiency, and strengthening grid resilience for storms and sea-level rise.

 

Key Points

It is an islandwide plan to electrify transport and buildings using wind, solar, storage, and a modern resilient grid.

✅ Electrify transport: EV adoption and SSA hybrid-electric ferries.

✅ Deploy heat pumps for efficient heating and cooling in buildings.

✅ Modernize the grid: distributed solar, batteries, microgrids, VPP.

 

Over the past year, it has become increasingly clear that climate change is accelerating. Here in coastal New England, annual temperatures and precipitation have risen more quickly than expected, tidal flooding is now commonplace, and storms have increased in frequency and intensity. The window for avoiding the worst consequences of a climate-changed planet is closing.

At their recent special town meeting, Oak Bluffs citizens voted to approve the 100 per cent renewable Martha’s Vineyard warrant article; now, all six towns have adopted the same goals for fossil fuel reduction and green electricity over the next two decades. Establishing these targets for the adoption of renewable energy, though, is only an initial step. Town and regional master plans for energy transformation are being developed, but this is a whole-community effort as well. Now is the time for action.

There is much to do to combat climate change, but our most important task is to transition our energy system from one heavily dependent on fossil fuels to one that is based on clean electricity. The good news is that this can be accomplished with currently available technology, and can be done in an economically efficient manner.

Electrification not only significantly lowers greenhouse gas emissions, but also is a powerful energy efficiency measure. So even though our detailed Island energy model indicates that eliminating all (or almost all) fossil fuel use will mean our electricity use will more than double, posing challenges for state power grids in some regions, our overall annual energy consumption will be significantly lower.

So what do we specifically need to do?

The primary targets for electrification are transportation (roughly 60 peer cent of current fossil fuel use on Martha’s Vineyard) and building heating and cooling (40 per cent).

Over the past two years, the increase in the number of electric vehicle models available across a wide range of price points has been remarkable — sedans, SUVs, crossovers, pickup trucks, even transit vans. When rebates and tax credits are considered, they are affordable. Range anxiety is being addressed both by increases in vehicle performance and the growing availability of charging locations (other than at home, which will be the predominant place for Islanders to refuel) and, over time, enable vehicle-to-grid support for our local system. An EV purchase should be something everyone should seriously consider when replacing a current fossil vehicle.

The elephant in the transportation sector room is the Steamship Authority. The SSA today uses roughly 10 per cent of the fossil fuel attributable to Martha’s Vineyard, largely but not totally in the ferries. The technology needed for fully electric short-haul vessels has been under development in Scandinavia for a number of years and fully electric ferries are in operation there. A conservative approach for the SSA would be to design new boats to be hybrid diesel-electric, retrofittable to plug-in hybrids to allow for shoreside charging infrastructure to be planned and deployed. Plug-in hybrid propulsion could result in a significant reduction in emissions — perhaps as much as 95 per cent, per the long-range plan for the Washington State ferries. While the SSA has contracted for an alternative fuel study for its next boat, given the long life of the vessels, an electrification master plan is needed soon.

For building heating and cooling, the answer for electrification is heat pumps, both for new construction and retrofits. These devices move heat from outside to inside (in the winter) or inside to outside (summer), and are increasingly integrated into connected home energy systems for smarter control. They are also remarkably efficient (at least three times more efficient than burning oil or propane), and today’s technology allows their operation even in sub-zero outside temperatures. Energy costs for electric heating via heat pumps on the Vineyard are significantly below either oil or propane, and up-front costs are comparable for new construction. For new construction and when replacing an existing system, heat pumps are the smart choice, and air conditioning for the increasingly hot summers comes with the package.

A frequent objection to electrification is that fossil-fueled generation emits greenhouse gases — thus a so-called green grid is required in order to meet our targets. The renewable energy fraction of our grid-supplied electricity is today about 30 per cent; by 2030, under current legislation that fraction will reach 54 per cent, and by 2040, 77 per cent. Proposed legislation will bring us even closer to our 2040 goals. The Vineyard Wind project will strongly contribute to the greening of our electricity supply, and our local solar generation (almost 10 per cent of our overall electricity use at this point) is non-negligible.

A final important facet of our energy system transformation is resilience. We are dependent today on our electricity supply, and this dependence will grow. As we navigate the challenges of climate change, with increasingly more frequent and more serious storms, 2021 electricity lessons underscore that resilience of electricity supply is of paramount importance. In many ways, today’s electricity distribution system is basically the same approach developed by Edison in the late 19th century. In partnership with our electric utility, we need to modernize the grid to achieve our resiliency goals.

While the full scope of this modernization effort is still being developed, the outline is clear. First, we need to increase the amount of energy generated on-Island — to perhaps 25 per cent of our total electricity use. This will be via distributed energy resources (in the form of distributed solar and battery installations as well as community solar projects) and the application of advanced grid control systems. For emergency critical needs, the concept of local microgrids that are detachable from the main grid when that grid suffers an outage are an approach that is technically sound and being deployed elsewhere. Grid coordination of distributed resources by the utility allows for handling of peak power demand; in the early 2030s this could result in what is known as a virtual power plant on the Island.

The adoption of the 100 renewable Martha’s Vineyard warrant articles is an important milestone for our community. While the global and national efforts in the climate crisis may sometimes seem fraught, we can take some considerable pride in what we have accomplished so far and will accomplish in coming years. As with many change efforts, the old catch-phrase applies: think globally, act locally.

FERC needs to review capacity market performance, GAO recommends

FERC Capacity Markets face scrutiny as GAO flags inconsistent data on resource adequacy and costs, urging performance goals, risk assessment, and better metrics across PJM, ISO-NE, NYISO, and MISO amid cost-recovery proposals.

 

Key Points

FERC capacity markets aim for resource adequacy, but GAO finds weak data and urges goals and performance reviews.

✅ GAO cites inconsistent data on resource adequacy and costs

✅ Calls for performance goals, metrics, and risk assessment

✅ Applies to PJM, ISO-NE, NYISO; MISO market is voluntary

 

Capacity markets may or may not be functioning properly, but FERC can't adequately make that determination, according to the GAO report.

"Available information on the level of resource adequacy ... and related costs in regions with and without capacity markets is not comprehensive or consistent," the report found. "Moreover, consistent data on historical trends in resource adequacy and related costs are not available for regions without capacity markets."

The review concluded that FERC collects some useful information in regions with and without capacity markets, but GAO said it "identified problems with data quality, such as inconsistent data."

GAO included three recommendations, including calling for FERC to take steps to improve the quality of data collected, and regularly assess the overall performance of capacity markets by developing goals for those assessments.

"FERC should develop and document an approach to regularly identify, assess, and respond to risks that capacity markets face," the report also recommended. The commission "has not established performance goals for capacity markets, measured progress against those goals, or used performance information to make changes to capacity markets as needed."

The recommendation comes as the agency is grappling with a controversial proposal to assure cost-recovery for struggling coal and nuclear plants in the power markets. So far, the proposal would only apply to power markets with capacity markets, including PJM Interconnection, the New England ISO, the New York ISO and possibly MISO. However MISO only has a voluntary capacity market, making it unclear how the proposed rule would be applied there.

Electricity subsidies to pulp and paper mills to continue, despite NB Power's rising debt

NB Power Pulp and Paper Subsidies lower electricity rates for six New Brunswick mills using firm power benchmarks and interruptible discounts, while government mandates, utility debt, ratepayer impacts, and competitiveness pressures shape provincial energy policy.

 

Key Points

Provincial mandates that buy down firm electricity rates for six mills to a national average, despite NB Power's debt.

✅ Mandated buy-down to match national firm electricity rates

✅ Ignores large non-firm interruptible power discounts

✅ Raises equity concerns amid NB Power debt and rate pressure

 

An effort to fix NB Power's struggling finances that is supposed to involve a look at "all options" will not include a review of the policy that requires the utility to subsidize electricity prices for six New Brunswick pulp and paper mills, according to the Department of Natural Resources and Energy Development.

The program is meant "to enable New Brunswick's pulp and paper companies have access to competitive priced electricity,"  said the department's communications officer Nick Brown in an email Monday 

"Keeping our large industries competitive with other Canadian jurisdictions, amid Nova Scotia rate hike opposition debates elsewhere, is important," he wrote, knocking down the idea the subsidy program might be scrutinized for shortcomings like other NB Power expenses.

Figures released last week show NB Power paid out $9.7 million in rate subsidies to the mills under the program in the fiscal year ended in March 2021, even though the utility was losing $4 million for the year and falling deeper into debt, amid separate concerns about old meter issues affecting households.

Subsidies went to three mills owned by J.D. Irving Ltd. including two in Saint John and one in Lake Utopia, two owned by the AV group in Nackawic and Atholville and the Twin Rivers pulp mill in Edmundston.

The New Brunswick government has made NB Power subsidize pulp and paper mills like Twin Rivers Paper Company since 2012, and is requiring the program to continue despite financial problems at the utility. (CBC)
It was NB Power's second year in a row of financial losses, while it is supposed to pay down $500 million of its $4.9 billion debt load in the next five years to prepare for the refurbishment of the Mactaquac dam, a burden comparable to customers in Newfoundland paying for Muskrat Falls elsewhere under separate policies, under a directive issued by the province

NB Power president Keith Cronkhite said he was "very disappointed" with debt increasing last year instead of  falling and senior vice president and chief financial officer Darren Murphy said everything would be under the microscope this year to turn the utility's finances around.  

"We need to do better," said Murphy on Thursday

"We need to step back and make sure we're considering all options, including approaches like Newfoundland's ratepayer shield agreement on megaproject overruns, to achieve that objective because the objective is quickly closing in on us."

However, reviewing the subsidy program for the six pulp and paper mills is apparently off limits.

The subsidy program requires NB Power to buy down the cost of "firm" electricity bought by pulp and paper mills to a national average that is calculated by the Department of Natural Resources and Energy Development.

Last year the province declared the price mills in New Brunswick pay to be an average of  7.536 cents per kilowatt hour (kwh).  It is higher than rates in five other provinces that have mills, which the province points to as justification for the subsidies, even as Nova Scotia's 14% rate hike approval highlights broader upward pressure, although the true significance of that difference is not entirely clear.

In British Columbia, the large forest products company Paper Excellence operates five pulp and paper mills which are charged 17.2 per cent less for firm electricity than the six mills in New Brunswick.

The Paper Excellence Paper Mill in Port Alberni, B.C. pays lower electricity prices than mills in New Brunswick, a benefit largely offset by higher property taxes. It's a factor New Brunswick does not count in calculating subsidies NB Power must pay. (Paper Excellence)
However, local property taxes on the five BC mills are a combined $7.8 million higher than the six New Brunswick plants, negating much of that difference.

The province's subsidy formula does not account for differences like that or for the fact New Brunswick mills buy a high percentage of their electricity at cheap non-firm prices.

Not counting the subsidies, NB Power already sells high volumes of what it calls interruptible and surplus power to industry at deep discounts on the understanding it can be cut off and redeployed elsewhere on short notice when needed.

Actual interruptions in service are rare.  Last year there were none, but NB Power sold 837 million kilowatt hours of the discounted power to industry at an average price of 4.9 cents per kwh.   

NB Power does not disclose how much of the $22 million or more in savings went to the six mills, but the price was 35 per cent below NB Power's posted rate for the plants and rivaled firm prices big mills receive anywhere in Canada, including Quebec.

Asked why the subsidy program ignores large amounts of discounted interruptible power used by New Brunswick mills in making comparisons between provinces, Brown said regulations governing the program require a comparison of firm prices only.

"The New Brunswick average rate is based on NB Power's published large industrial rate for firm energy, as required by the Electricity from Renewable Resources regulation," he wrote.

The subsidy program itself was imposed on NB Power by the province in 2012 to aid companies suffering after years of poor markets for forest products following the 2008 financial collapse and recession.  

Providing subsidies has cost NB Power $100 million so far and has continued even as markets for pulp products improved significantly and NB Power's own finances worsened.

Report warned against subsidies
NB Power has never directly criticized the program, but in a matter currently in front the of the New Brunswick Energy and Utilities Board looking at how NB Power might restructure its rates, including proposals such as seasonal rates that could prompt backlash, an independent consultant hired by the utility suggested rate subsidies to large export oriented manufacturing facilities, like pulp and paper mills, is generally a poor idea.

"We do not recommend offering subsidies to exporters," says the report by Christensen Associates Energy Consulting of Madison, Wis.

"There are two serious economic problems with subsidizing exports. The first is that the benefits may be less than the costs. The second problem is that subsidies tend to last forever, even if the circumstances that initially justified the subsidies have disappeared."

The Christensen report did not directly assess the merits of the current subsidy for pulp and paper mills but it addressed the issue because it said in the design of new rates "one NB Power business customer has raised the possibility that their electricity-intensive business ought to be granted subsidies because of the potential to generate extra benefits for the Province through increases in their exports"

That, said Christensen, rarely benefits the public.

"The direct costs of the subsidies are the subsidies themselves, a part of which ends up in the pockets of out-of-province consumers of the exported goods," said the report.  

"But there are also indirect costs due to the fact that the subsidies are financed through higher electricity prices, which means that other electricity customers have less money to spend on services provided by local businesses, thus putting a drag on the local economy."

The province does not agree.

Asked whether it has any studies or cost-benefit reviews that show the subsidy program is a net benefit to New Brunswick, the department cited none but maintained it is an important initiative, even as elsewhere governments have offered electricity bill credit relief to ratepayers.

"The program was designed to give large industrial businesses the ability to compete on a level energy field," wrote Brown.

Prevent Summer Power Outages

Summer Heatwave Electricity Shutoffs strain utilities and vulnerable communities, highlighting energy assistance, utility moratoriums, cooling centers, demand response, and grid resilience amid extreme heat, climate change, and rising air conditioning loads.

 

Key Points

Service disconnections for unpaid bills during extreme heat, risking vulnerable households and straining power grids.

✅ Moratoriums and flexible payment plans reduce shutoff risk.

✅ Cooling centers and assistance programs protect at-risk residents.

✅ Demand response, smart grids, and efficiency ease peak loads.

 

As summer temperatures soar, millions of people across the United States face the grim prospect of electricity shutoffs due to unpaid bills, as heat exacerbates electricity struggles for many families nationwide. This predicament highlights a critical issue exacerbated by extreme weather conditions and economic disparities.

The Challenge of Summer Heatwaves

Summer heatwaves not only strain power grids, as unprecedented electricity demand has shown, but also intensify energy consumption as households and businesses crank up their air conditioning units. This surge in demand places considerable stress on utilities, particularly in regions unaccustomed to prolonged heatwaves or lacking adequate infrastructure to cope with increased loads.

Vulnerable Populations

The threat of electricity shutoffs disproportionately affects vulnerable populations, including low-income households who face sky-high energy bills during extreme heat, elderly individuals, and those with underlying health conditions. Lack of access to air conditioning during extreme heat can lead to heat-related illnesses such as heat exhaustion and heatstroke, posing serious health risks.

Economic and Social Implications

The economic impact of electricity shutoffs extends beyond immediate discomfort, affecting productivity, food storage, and the ability to work remotely for those reliant on electronic devices, while rising electricity prices further strain household budgets. Socially, the inability to cool homes and maintain basic comforts strains community resilience and exacerbates inequalities.

Policy and Community Responses

In response to these challenges, policymakers and community organizations advocate for measures to prevent electricity shutoffs during heatwaves. Proposed solutions include extending moratoriums on shutoffs, informed by lessons from COVID-19 energy insecurity measures, implementing flexible payment plans, providing financial assistance to at-risk households, and enhancing communication about available resources.

Public Awareness and Preparedness

Raising public awareness about energy conservation during peak hours and promoting strategies to stay cool without overreliance on air conditioning are crucial steps towards mitigating electricity demand. Encouraging energy-efficient practices and investing in renewable energy sources also contribute to long-term resilience against climate-driven energy challenges.

Collaborative Efforts

Collaboration between government agencies, utilities, nonprofits, and community groups is essential in developing comprehensive strategies to safeguard vulnerable populations during heatwaves, especially when systems like the Texas power grid face renewed stress during prolonged heatwaves. By pooling resources and expertise, stakeholders can better coordinate emergency response efforts, distribute cooling centers, and ensure timely assistance to those in need.

Technology and Innovation

Advancements in smart grid technology and decentralized energy solutions offer promising avenues for enhancing grid resilience and minimizing disruptions during extreme weather events. These innovations enable more efficient energy management, demand response programs, and proactive monitoring of grid stability, though some utilities face summer supply-chain constraints that delay deployments.

Conclusion

As summer heatwaves become more frequent and severe, the risk of electricity shutoffs underscores the urgent need for proactive measures to protect vulnerable communities. By prioritizing equity, sustainability, and resilience in energy policy and practice, stakeholders can work towards ensuring reliable access to electricity, particularly during times of heightened climate vulnerability. Addressing these challenges requires collective action and a commitment to fostering inclusive and sustainable solutions that prioritize human well-being amid changing climate realities.

Westinghouse AP1000 Nuclear Plant Breaks A First Refueling Outage Record

AP1000 Refueling Outage Record showcases Westinghouse nuclear power excellence as Sanmen Unit 2 completes its first reactor refueling in 28.14 days, highlighting safety, reliability, outage optimization, and economic efficiency in China.

 

Key Points

It is the 28.14-day initial refueling at Sanmen Unit 2, a global benchmark achieved with Westinghouse AP1000 technology.

✅ 28.14-day first refueling at Sanmen Unit 2 sets global benchmark

✅ AP1000 design simplifies systems, improves safety and reliability

✅ Outage optimization by Westinghouse and CNNC accelerates schedules

 

Westinghouse Electric Company China operations today announced that Sanmen Unit 2, one of the world's first AP1000® nuclear power plants, has set a new refueling outage record in the global nuclear power industry, completing its initial outage in 28.14 days.

"Our innovative AP1000 technology allows for simplified systems and significantly reduces the amount of equipment, while improving the safety, reliability and economic efficiency of this nuclear power plant, reflecting global nuclear milestones reached recently," said Gavin Liu, president of the Westinghouse Asia Operating Plant Services Business. "We are delighted to see the first refueling outage for Sanmen Unit 2 was completed in less than 30 days. This is a great achievement for Sanmen Nuclear Power Company and further demonstrates the outstanding performance of AP1000 design."

All four units of the AP1000 nuclear power plants in China have completed their first refueling outages in the past 18 months, aligning with China's nuclear energy development momentum across the sector.  The duration of each subsequent outage has fallen significantly - from 46.66 days on the first outage to 28.14 days on Sanmen Unit 2.

"During the first AP1000 refueling outage at the Sanmen site in December 2019, a Westinghouse team of experts worked side-by-side with the Sanmen outage team to partner on outage optimization, and immediately set a new standard for a first-of-a-kind outage, while major refurbishments like the Bruce refurbishment moved forward elsewhere," said Miao Yamin, chairman of CNNC Sanmen Nuclear Power Company Limited. "Lessons learned were openly exchanged between our teams on each subsequent outage, which has built to this impressive achievement."

Westinghouse provided urgent technical support on critical issues during the outage, as international programs such as Barakah Unit 1 achieved key milestones, to help ensure that work was carried out on schedule with no impact to critical path.

In addition to the four AP1000 units in China, two units are under construction at the Vogtle expansion near Waynesboro, Georgia, USA.

Separately, in the United States, a new reactor startup underscored renewed momentum in nuclear generation this year.

The Phillipines wants nuclear power to be included in the country's energy mix as the demand for electricity is expected to rise.

Philippines Nuclear Energy Policy aims to add nuclear power to the energy mix via executive order, meeting rising electricity demand with 24/7 baseload while balancing safety, renewables, and imported fuel dependence in the Philippines.

 

Key Points

A government plan to include nuclear power in the energy mix to meet demand, ensure baseload, and uphold safety.

✅ Executive order proposed by Energy Secretary Alfonso Cusi

✅ Targets 24/7 baseload, rising electricity demand

✅ Balances safety, renewables, and energy security

 

Phillipines Presidential spokesman Salvador Panelo said Energy Secretary Alfonso Cusi made the proposal during last Monday's Cabinet meeting in Malacaaang. "Secretary Cusi likewise sought the approval of the issuance of a proposed executive order for the inclusion of nuclear power, including next-gen nuclear options in the country's energy mix as the Philippines is expected to the rapid growth in electricity and electricity demand, in which, 24/7 power is essential and necessary," Panelo said in a statement.

Panelo said Duterte would study the energy chief's proposal, as China's nuclear development underscores regional momentum. In the 1960s until the mid 80s, the late president Ferdinand Marcos adopted a nuclear energy program and built the Bataan Nuclear Plant.

The nuclear plant was mothballed after Corazon Aquino became president in 1986. There have been calls to revive the nuclear plant, saying it would help address the Philippines' energy supply issues. Some groups, however, said such move would be expensive and would endanger the lives of people living near the facility, citing Three Mile Island as a cautionary example.

Panelo said proposals to revive the Bataan Nuclear Plant were not discussed during the Cabinet meeting, even as debates like California's renewable classification continue to shape perceptions. Indigenous energy sources natural gas, hydro, coal, oil, geothermal, wind, solar, biomassand ethanol constitute more than half or 59.6%of the Philippines' energy mix.

Imported oil make up 31.7% while imported coal, reflecting the country's coal dependency, contribute about 8.7%.

Imported ethanol make up 0.1% of the energy mix, even as interest in atomic energy rises globally.

In 2018, Duterte said safety should be the priority when deciding whether to tap nuclear energy for the country's power needs, as countries like India's nuclear restart proceed with their own safeguards.
