Sweden eyes nuclear revival after 30-year ban

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

Bruce Power Capacity Uprate boosts nuclear output through generator stator upgrades, turbine and transformer enhancements, and cooling pump improvements at Bruce A and B, unlocking megawatts and efficiency gains from legacy heavy water design capacity.

Key Points

Upgrades that raise Bruce Power capacity via stator, turbine, transformer, and cooling enhancements.

✅ Generator stator replacement increases electrical conversion efficiency

✅ Turbine and transformer upgrades enable higher MW output

✅ Cooling pump enhancements optimize plant thermal performance

Bruce Power’s Unit 3 nuclear reactor will squeeze out an extra 22 megawatts of electricity, thanks to upgrades during its recent planned outage for refurbishment.

Similar gains are anticipated at its three sister reactors at Bruce A generating station, which presents the opportunity for the biggest efficiency gains and broader economic benefits for Ontario, due to a design difference over Bruce B’s four reactors, Bruce Power spokesman John Peevers said.

Bruce A reactor efficiency gains stem mainly from the fact Bruce A’s non-nuclear side, including turbines and the generator, was sized at 88 per cent of the nuclear capacity, Peevers said, while early Bruce C exploration work advances.

This allowed 12 per cent of the energy, in the form of steam, to be used for heavy water production, which was discontinued at the plant years ago. Heavy water, or deuterium, is used to moderate the reactors.

That design difference left a potential excess capacity that Bruce Power is making use of through various non-nuclear enhancements. But the nuclear operator, which also made major PPE donations during the pandemic, will be looking at enhancements at Bruce B as well, Peevers said.

Bruce Power’s efficiency gain came from “technology advancements,” including a “generator-stator improvement project that was integral to the uprate,” and contributed to an operating record at the site, a Bruce Power news release said July 11.

Peevers said the stationary coils and the associated iron cores inside the generator are referred to as the stator. The stator acts as a conductor for the main generator current, while the turbine provides the mechanical torque on the shaft of the generator.

“Some of the other things we’re working on are transformer replacement and cooling pump enhancements, backed by recent manufacturing contracts, which also help efficiency and contribute to greater megawatt output,” Peevers said.

The added efficiency improvements raised the nuclear operator’s peak generating capacity to 6,430 MW, as projects like Pickering life extensions continue across Ontario.

Manitoba Hydro Phone Scam targets small businesses with disconnection threats, prepaid card payments, caller ID spoofing, phishing texts, and door-to-door fraud; hang up, verify your account directly, and never share banking information.

Key Points

A scam where callers threaten disconnection and demand prepaid cards; verify account status directly with Manitoba Hydro.

✅ Hang up and call Manitoba Hydro at 1-888-624-9376 to verify.

✅ Never pay by prepaid cards, gift cards, or crypto.

✅ Hydro will not cut power on one-hour notice.

Manitoba Hydro is warning customers, particularly small business owners, to be wary of high-pressure scammers, as Ontario utilities warn of scams in other provinces, threatening to shut off their electricity.

The callers demand the customer to make immediate payment by a prepaid card. Often, the calls are made in the middle of the day at a busy time, frightening the customer with aggressive threats about disconnection, as hydro disconnections have made headlines elsewhere, says hydro spokesman Bruce Owen.

"They tell them 'we have a truck on the way to cut off your power. If you don't pay in the next hour you're out of luck,'" he said.

"And because these folks have inventory in freezers and they have customers … they're willing to fork over several hundred or even several thousand dollars on a prepaid card to somebody they don't know to keep the lights on."

Maybe the business owners can't recall, with everything happening, including discussions about Hydro One peak rates in Ontario, if they've made their payments on time. They start second-guessing and believing the person on the other line, Owen says.

And they worry about losing thousands of dollars in business if they lose power. So they're more than willing to run out to a store, buy a prepaid debit card and provide the number to the caller.

"Their goal is to manipulate you into sending money before you figure out it's a scam," said Chris McColm, hydro's security and investigations supervisor. "These people are crooks and you should hang up on them."

For any customers that are in arrears, hydro will work with them to resolve the issue, Owen said.

"We do not have to take that extreme measure of cutting off or disconnecting anybody. That's not the business we're in — we don't strong arm people that way," he said.

"Anybody who's threatening to cut off your power with an hour or half-an-hour notice, well it's it's no better than someone waiting around the corner, waiting the club you over the head in the dark of night. That's what they are."

Fraud reports soar

The power utility has recorded a nearly-300 per cent jump in the number of fraud-related complaints this year over 2017. There have been 862 phone, text and e-mail scams and that could still go much higher.

The current statistics from 2018 have only calculated up to Oct. 31. In 2017, there were 221.

That jump in numbers doesn't necessarily mean there are more scammers out there.

It could simply mean people are finally getting wise to fraudsters and reporting it more, Owen says.

"At the same token, we don't hear of everybody who's been taking advantage of because once they've found out that they've been hoodwinked they don't want to tell anybody because they're so embarrassed," he said.

"These scammers can be very convincing and anyone can be victimized," McColm said.

If you are able to think clearly when some high-pressure caller gets you on the line, Owen suggests asking a few simple questions to challenge their legitimacy:

• What street am I on?
• What does my business look like? 
• What's the weather outside right now?

Phone scammers can falsify their caller ID information to make it appear they're calling from a local number, but what you'll find is most of them aren't in Winnipeg or Manitoba and likely not even this country or continent, Owen says.

The key to being safe is simply to never give out banking information, Owen says. It's a message that has been stressed for years and 80-90 per cent of people understand it, but it's that other 10-20 per cent that are still being victimized.And it's not just phone calls. Many other fraud-related complaints to Manitoba Hydro this year concerned unsolicited text messages to customers saying they had been overbilled, or faced retroactive charges elsewhere, and were eligible for a refund.

This scam is also aimed at getting a customer's personal banking information, under the guise of having money put back into their account.

Also, many people, especially seniors living alone, continue to be targeted by aggressive door-to-door fraudsters, and cases like the electricity theft ring in Montreal underscore the risks, McColm says. However, he adds, hydro employees always display photo ID and will never demand to come into a home. 

If you're unsure whether a phone call, text or email is real or a scam, contact Manitoba Hydro at 1-888-624-9376.

German Energy Price Brakes harness price signals in a market-based policy, cutting gas consumption, preserving industrial output, and supporting CO2 reduction, showcasing Germany's resilience and adaptation while protecting households and businesses across Europe.

Key Points

Fixed-amount subsidies preserving price signals to curb gas use, shield consumers, and sustain industrial output.

✅ Maintains incentives via market-based price signals

✅ Cuts gas consumption without distorting EU markets

✅ Protects households and industry while curbing CO2

German industry and society are once again proving much more resilient and adaptable than certain people feared. Horror scenarios of a dangerous energy rationing or a massive slump in our economy have often been bandied about. But we are nowhere near that. With a challenging year just behind us, this is good news — not only for Germany, but also for Europe, where France-Germany energy cooperation has strengthened solidarity.

Companies and households reacted swiftly to the sharp increases in energy prices, in line with momentum in the global energy transition seen across markets. They installed more efficient heating or production facilities, switched to alternatives and imported intermediate products. The results are encouraging: German households and businesses have reduced gas consumption significantly, despite recent cold weather. From the start of the war in Ukraine to mid-December industrial gas consumption in Germany was (temperature-adjusted) around 20 per cent lower than the average level for the preceding three years. Even if some firms have cut back production, especially in energy-intensive sectors, industrial output as a whole has only fallen by about 1 per cent since the start of 2022. Added to this, in a survey released by the Ifo institute in November, over a third of German companies saw the potential to reduce gas consumption further without endangering output.

Instead of imposing excessive laws and regulations, we have relied on price signals and the prudence of market participants to create the right incentives and reduce gas consumption, as falling costs like record-low solar power prices continue to reinforce those signals across sectors.

We will follow this approach in coming months, when energy savings will remain important, even as the EU electricity outlook anticipates sharply higher demand by 2050. Our latest relief measures will not distort price signals. To this end, the Bundestag approved gas and electricity price brakes in its final session in 2022. They are designed to function without any intervention in markets or prices. This system will pay out a fixed amount relative to previous years’ consumption and the current difference to a reference price — regardless of current consumption.

Energy price brakes are the main component of Germany’s “protective shield”, which makes up to €200bn available for measures in 2022 to 2024. Seen in relation to the German economy’s size, its past heavy reliance on Russian energy imports and the fact that the measures will expire in 2024, these are balanced and expedient mechanisms. In contrast to instruments used in other countries, our new arrangements will not affect the price formation process driven by supply and demand, or on incentives to save gas. Companies and households will continue to save the full market price when they reduce consumption by a unit of gas or electricity. In this way, the price brakes also avoid the creation of additional demand for gas at the expense of consumers in other European countries, even as Europe’s Big Oil turning electric signals broader structural shifts in energy markets. No one need fear that competition will be distorted or that gas will be bought up. Indeed, a recent IMF working paper on cushioning the impact of high energy prices on households explicitly praises the German energy price brakes.

Current developments confirm the effectiveness of a market-based approach — and show that we should also rely on price signals when it comes to reducing CO₂ emissions, as suggested by IEA CO2 trends in recent years. Last year, households and companies had only a few weeks to adapt, yet we have already seen a strong response. The effect of CO₂ prices can be even stronger, as adaptation is possible over a much longer time and they additionally affect expectations and long-term decisions. Regulatory interventions and subsidy schemes, even if well targeted, cannot compete with market co-ordination and incentives that support individual decision-making and promote innovation.

Europe and Germany can weather this crisis without a collapse in industrial production. We also have an opportunity to deal efficiently with the move to climate neutrality, aligned with Germany’s hydrogen strategy for imported low-carbon fuels. In both cases, we should have confidence in price signals as well as in the power of people and business to innovate and adapt.

OPG Credit Rating affirmed by DBRS at A (low) issuer and unsecured debt, R-1 (low) CP, Stable trends, backed by a supportive regulatory regime, strong leverage metrics, and provincial support; monitor Darlington Refurbishment costs.

Key Points

It is DBRS's confirmation of OPG at A (low) issuer and unsecured, R-1 (low) CP, with Stable outlooks.

✅ Stable trends; strong cash flow-to-debt and capital ratios

✅ Provincial financing via OEFC; Fair Hydro Trust ring-fenced

✅ Darlington Refurbishment on budget; cost overruns remain risk

DBRS Limited (DBRS) confirmed the Issuer Rating and the Unsecured Debt rating of Ontario Power Generation Inc. (OPG or the Company) at A (low) and the Commercial Paper (CP) rating at R-1 (low), amid sector developments such as Hydro One leadership efforts to repair government relations and measures like staff lockdowns at critical sites.

All trends are Stable. The ratings of OPG continue to be supported by (1) the reasonable regulatory regime in place for the Company's regulated generation facilities, including stable pricing signals for large users, (2) strong cash flow-to-debt and debt-to-capital ratios and (3) continuing financial support from its shareholder, the Province of Ontario (the Province; rated AA (low) with a Stable trend by DBRS). The Province, through its agent, the Ontario Electricity Financial Corporation (rated AA (low) with a Stable trend by DBRS), provides most of OPG's financing (approximately 43% of consolidated debt). The Company's remaining debt includes project financing (31%), including projects such as a battery energy storage system proposed near Woodstock, non-recourse debt issued by Fair Hydro Trust (Senior Notes rated AAA (sf), Under Review with Negative Implications by DBRS; 11%), CP (2%) and Senior Notes issued under the Medium Term Note Program (12%).

In March 2019, the Province introduced 'Bill 87, Fixing the Hydro Mess Act, 2019' which includes winding down the Fair Hydro Plan, and later introduced electricity relief to mitigate customer bills during the COVID-19 pandemic. OPG will remain as the Financial Services Manager for the outstanding Fair Hydro Trust debt, which will become obligations of the Province. DBRS does not expect this development to have a material impact on the Company as (1) the Fair Hydro Trust debt will continue to be bankruptcy-remote and ring-fenced from OPG (all debt is non-recourse to the Company) and (2) the credit rating on the Company's investment in the Subordinated Notes (rated AA (sf), Under Review with Negative Implications by DBRS) will likely remain investment grade while the Junior Subordinated Notes (rated A (sf), Under Review with Developing Implications by DBRS) will not necessarily be negatively affected by this change (see the DBRS press release, 'DBRS Maintains Fair Hydro Trust, Series 2018-1 and Series 2018-2 Notes Under Review,' dated March 26, 2019, for more details).

OPG's key credit metrics improved in 2018, following the approval of its 2017-2021 rates application by the Ontario Energy Board in December 2017, alongside the Province's energy-efficiency programs that shape demand. The Company's profitability strengthened significantly, with corporate return on equity (ROE) of 7.8% (adjusted for a $205 million gain on sale of property; 5.1% in 2017) closer to the regulatory allowed ROE of 8.78%. However, DBRS continues to view a positive rating action as unlikely in the short term because of the ongoing large capital expenditures program, including the $12.8 billion Darlington Refurbishment project, amid ongoing oversight following the nuclear alert investigation in Ontario. However, a downgrade could occur should there be significant cost overruns with the Darlington Refurbishment project that result in stranded costs. DBRS notes that the Darlington Refurbishment project is currently on budget and on schedule.
