IAEA OSART Cernavoda highlights strengthened operational safety at Romania’s Cernavoda NPP, citing improved maintenance practices, simulator training, and deficiency reporting, with ongoing actions on spare parts procurement, procedure updates, and chemical control for nuclear compliance.

 

Key Points

An IAEA follow-up mission confirming improved operational safety at Cernavoda NPP, with remaining actions tracked.

✅ Enhanced simulator training and crew performance

✅ Improved field deficiency identification and reporting

✅ Ongoing upgrades to procedures, spares, and chemical control

 

The International Atomic Energy Agency (IAEA) said yesterday that the operator of Romania’s Cernavoda nuclear power plant had demonstrated "strengthened operational safety" by addressing the findings of an initial IAEA review in 2016. The Operational Safety Review Team (OSART) concluded a five-day follow-up mission on 8 March to the Cernavoda plant, which is on the Danube-Black Sea Canal, about 160 km from Bucharest.

The plant's two 706 MWe CANDU pressurised heavy water reactors, reflecting Canadian nuclear projects, came online in 1996 and 2007, respectively.

The OSART team was led by Fuming Jiang, a senior nuclear safety officer at the IAEA, which recently commended China's nuclear security in separate assessments.

"We saw improvements in key areas, such as the procurement of important spare parts, the identification and reporting of some deficiencies, and some maintenance work practices, as evidenced by relevant performance indicators," Jiang said, noting milestones at nuclear projects worldwide this year.

The team observed that several findings from the 2016 review had been fully addressed, including: enhanced operator crew performance during simulator training; better identification and reporting of deficiencies in the field; and improvement in maintenance work practices.

More time is required, it said, to fully implement some actions, including: further improvements in the procurement of important spare parts with relevance to safety; further enhancement in the revision and update of some operating procedures, drawing on lessons from Pickering NGS life extensions undertaken in Ontario; and control and labelling of some plant chemicals.

Dan Bigu, site vice president of Cernavoda NPP, said the 2016 mission had "proven to be very beneficial", adding that the current follow-up mission would "provide further catalyst support to our journey to nuclear excellence".

The team provided a draft report of the mission to the plant's management and a final report will be submitted to the Romanian government, which recently moved to terminate talks with a Chinese partner on a separate nuclear project, within three months.

OSART missions aim to improve operational safety by objectively assessing safety performance, even as the agency reports mines at Ukraine's Zaporizhzhia plant amid ongoing risks, using the IAEA's safety standards and proposing recommendations and suggestions for improvement where appropriate. The follow-up missions are standard components of the OSART programme and, as the IAEA has warned of risks from attacks on Ukraine's power grids, are typically conducted within two years of the initial mission.

European Power Hits Records as Plants Start to Buckle in Heat

European Power Crisis intensifies as record electricity prices, nuclear output cuts, gas supply strain, heatwave drought, and Rhine shipping bottlenecks hit Germany, France, and Switzerland, tightening winter storage and driving long-term contracts higher.

 

Key Points

A surge in European power prices from heatwaves, nuclear curbs, Rhine coal limits, and reduced Russian gas supply.

✅ Record year-ahead prices in Germany and France

✅ Nuclear output curbed by warm river cooling limits

✅ Rhine low water disrupts coal logistics and generation

 

Benchmark power prices in Europe hit fresh records Friday as utilities are increasingly reducing electricity output in western Europe because of the hot weather. 

Next-year contracts in Germany and France, Europe’s biggest economies rose to new highs after Switzerland’s Axpo Holding AG announced curbs at one of its nuclear plants. Electricite de France SA is also reducing nuclear output because of high river temperatures and cooling water restrictions, while Uniper SE in Germany is struggling to get enough coal up the river Rhine. 

Europe is suffering its worst energy crunch in decades, and losing nuclear power is compounding the strain as gas cuts made by Russia in retaliation for sanctions drive a surge in prices. The extreme heat led to the driest July on record in France and is underscoring the impact that a warming climate is having on vital infrastructure.

Water levels on Germany’s Rhine have fallen so low that the river may effectively close soon, impacting supplies of coal to the plants next to it. The Rhone and Garonne in France and the Aare in Switzerland are all too warm to be used to cool nuclear plants effectively, forcing operators to limit energy output under environmental constraints. 

Northwest European weather forecast for the next two weeks:
relates to European Power Hits Records as Plants Start to Buckle in Heat
  
The German year-ahead contract gained as much as 2% to 413 euros a megawatt-hour on the European Energy Exchange AG. The French equivalent rose 1.9% to a record 535 euros. Long-term prices are coming under pressure because producing less power from nuclear and coal will increase the demand for natural gas, which is badly needed to fill storage sites ahead of the winter.  


France to Curb Nuclear Output as Europe’s Energy Crisis Worsens
Uniper SE said on Thursday that two of its coal-fired stations along the Rhine may need to curb output during the next few weeks as transporting coal along the Rhine becomes impossible. 

Plants on the river near Mannheim and Karlsruhe, operated by Grosskraftwerk Mannheim AG and EnBW AG, have previously struggled to source coal because of the shallow water, even as German renewables deliver more electricity than coal and nuclear at times. Both companies said generation hasn’t been affected yet. 

“The low tide is not currently affecting our generation of energy because our plants do not have the need for continuous fresh water,” a Steag GmbH spokesman said on Friday. “But the low tide level can make running plants and transporting coal more complicated than usual.”

The spokesman said though that there is slight reduction in output of about 10 to 15 megawatts, which would equate to a few percent, because of the hot temperatures. “This has been happening over some time now and is a problem for everyone because the plant system is not designed to withstand such hot temperatures,” he said.

Barakah Unit 1 reaches 100% power as it steps closer to commercial operations, due to begin early 2021

Barakah Unit 1 100 Percent Power signals the APR-1400 reactor delivering 1400MW of clean baseload electricity to the UAE grid, advancing decarbonisation, reliability, and Power Ascension Testing milestones ahead of commercial operations in early 2021.

 

Key Points

The milestone where Unit 1 reaches full 1400MW output to the UAE grid, providing clean, reliable baseload electricity.

✅ Delivers 1400MW from a single generator to the UAE grid

✅ Enables clean, reliable baseload power with zero operational emissions

✅ Completes key Power Ascension Testing before commercial operations

 

The Emirates Nuclear Energy Corporation, ENEC, has announced that its operating and maintenance subsidiary, Nawah Energy Company, Nawah, has successfully achieved 100% of the rated reactor power capacity for Unit 1 of the Barakah Nuclear Energy Plant. This major milestone, seen as a crucial step in Abu Dhabi towards completion, brings the Barakah plant one step closer to commencing commercial operations, scheduled in early 2021.

100% power means that Unit 1 is generating 1400MW of electricity from a single generator connected to the UAE grid for distribution. This milestone makes the Unit 1 generator the largest single source of electricity in the UAE.

The Barakah Nuclear Energy Plant is the largest source of clean baseload electricity in the country, capable of providing constant and reliable power in a sustainable manner around the clock. This significant achievement accelerates the decarbonisation of the UAE power sector, while also supporting the diversification of the Nation’s energy portfolio as it transitions to cleaner electricity sources, similar to the steady development in China of nuclear energy programs now underway.

The accomplishment follows shortly after the UAE’s celebration of its 49th National Day, providing a strong example of the country’s progress as it continues to advance towards a sustainable, clean, secure and prosperous future, having made the UAE the first Arab nation to open a nuclear plant as it charts this path. As the Nation looks towards the next 50 years of achievements, the Barakah plant will generate up to 25 percent of the country’s electricity, while also acting as a catalyst of the clean carbon future of the Nation.

Mohamed Ibrahim Al Hammadi, Chief Executive Officer of ENEC said: "We are proud to deliver on our commitment to power the growth of the UAE with safe, clean and abundant electricity. Unit 1 marks a new era for the power sector and the future of the clean carbon economy of the Nation, with the largest source of electricity now being generated without any emissions. I am proud of our talented UAE Nationals, working alongside international experts who are working to deliver this clean electricity to the Nation, in line with the highest standards of safety, security and quality." Nawah is responsible for operating Unit 1 and has been responsible for safely and steadily raising the power levels since it commenced the start-up process in July, and connection to the grid in August.

Achieving 100% power is one of the final steps of the Power Ascension Testing (PAT) phase of the start-up process for Unit 1. Nawah’s highly skilled and certified nuclear operators will carry out a series of tests before the reactor is safely shut down in preparation for the Check Outage. During this period, the Unit 1 systems will be carefully examined, and any planned or corrective maintenance will be performed to maintain its safety, reliability and efficiency prior to the commencement of commercial operations.

Ali Al Hammadi, Chief Executive Officer of Nawah, said: "This is a key achievement for the UAE, as we safely work through the start-up process for Unit 1 of the Barakah plant. Successfully reaching 100% of the rated power capacity in a safe and controlled manner, undertaken by our highly trained and certified nuclear operators, demonstrates our commitment to safe, secure and sustainable operations as we now advance towards our final maintenance activities and prepare for commercial operations in 2021." The Power Ascension Testing of Unit 1 is overseen by the independent national regulator – the Federal Authority for Nuclear Regulation (FANR), which has conducted 287 inspections since the start of Barakah’s development. These independent reviews have been conducted alongside more than 40 assessments and peer reviews by the International Atomic Energy Agency, IAEA, and World Association of Nuclear Operators, WANO, reflecting milestones at nuclear projects worldwide that benchmark safety and performance.

This is an important milestone for the commercial performance of the Barakah plant. Barakah One Company, ENEC’s subsidiary in charge of the financial and commercial activities of the Barakah project signed a Power Purchase Agreement, PPA, with the Emirates Water and Electricity Company, EWEC, in 2016 to purchase all of the electricity generated at the plant for the next 60 years. Electricity produced at Barakah feeds into the national grid in the same manner as other power plants, flowing to homes and business across the country.

This milestone has been safely achieved despite the challenges of COVID-19. Since the beginning of the global pandemic, ENEC, and subsidiaries Nawah and Barakah One Company, along with companies that form Team Korea, including Korea Hydro & Nuclear Power, with KHNP’s work in Bulgaria illustrating its global role, have worked closely together, in line with all national and local health authority guidelines, to ensure the highest standards for health and safety are maintained for those working on the project. ENEC and Nawah’s robust business continuity plans were activated, alongside comprehensive COVID-19 prevention and management measures, including access control, rigorous testing, and waste water sampling, to support health and wellbeing.

The Barakah Nuclear Energy Plant, located in the Al Dhafra region of the Emirate of Abu Dhabi, is one of the largest nuclear energy new build projects in the world, with four APR-1400 units. Construction of the plant began in 2012 and has progressed steadily ever since. Construction of Units 3 and 4 are in the final stages with 93 percent and 87 percent complete respectively, benefitting from the experience and lessons learned during the construction of Units 1 and 2, while the construction of the Barakah Plant as a whole is now more than 95 percent complete.

Once the four reactors are online, Barakah Plant will deliver clean, efficient and reliable electricity to the UAE grid for decades to come, providing around 25 percent of the country’s electricity and, as other nations like Bangladesh expand with IAEA assistance, reinforcing global decarbonisation efforts, preventing the release of up to 21 million tons of carbon emissions annually – the equivalent of removing 3.2 million cars off the roads each year.

Texas Utilities back out of deal to create smart home electricity networks

Smart Meter Texas real-time pricing faces rollback as utilities limit on-demand reads, impacting demand response, home area networks, ERCOT wholesale tracking, and thermostat automation, reducing efficiency gains promised through deregulation and smart meter investments.

 

Key Points

A plan linking smart meters to ERCOT prices, enabling near real-time usage alignment and automated demand response.

✅ Twice-hourly reads miss 15-minute ERCOT price spikes.

✅ Less than 1% of 7.3M meters use HAN real-time features.

✅ Limits hinder automation for HVAC, EV charging, and pool pumps.

 

Utilities made a promise several years ago when they built Smart Meter Texas that they’d come up with a way for consumers to monitor their electricity use in real time. But now they’re backing out of the deal with the approval of state regulators, leaving in the lurch retail power companies that are building their business model on the promise of real time pricing and denying consumers another option for managing their electricity costs.

Texas utilities collected higher rates to finance the building of a statewide smart meter network that would allow customers to track their electricity use and the quickly changing prices on wholesale power markets almost as they happened. Some retailers are building electricity plans around this promise, providing customers with in-home devices that would eventually track pricing minute-by-minute and allow them to automatically turn down or shut off air conditioners, pool pumps and energy sucking appliances when prices spiked on hot summer afternoons and turn them back on when they prices fell again.

The idea is to help save consumers money by allowing them to shift their electricity consumption to periods when power is cheaper, typically nights and weekends, even as utility revenue in a free-power era remains a debated topic.

“We’re throwing away a large part of (what) ratepayers paid for,” said John Werner, CEO of GridPlus Texas, one of the companies offering consumers a real-time pricing plan that is scheduled to begin testing next month. “They made the smart meters dumb meters.”

When Smart Meter Texas was launched a decade ago by a consortium of the state’s biggest utilities, it was considered an important part of deregulation. The competitive market for electricity held the promise that consumers would eventually have the technology to control their electricity use through a home area network and cut their power bills.

Regulators and legislators also were enticed by the possibility of making the electric system more efficient and relieving pressure on the power grid as consumers responded to high prices and cut consumption when temperatures soared, with ongoing discussions about Texas grid reliability informing policy choices.

One study found that smart meters coupled with smart real time consumption monitors could reduce electricity use between 3 percent and 5 percent, according to Call Me Power, a website sponsored by the European electricity price shopping service Selectra.

But utilities complained that the home area network devices were expensive to install and not used very often, and, with flat electricity demand weighing on growth, they questioned further investment. CenterPoint manager Esther Floyd Kent filed an affidavit with the commission in May that it costs the utility about $30,000 annually to support the network devices, plus maintenance.

Over a six-year period, CenterPoint paid $124,500, or about $20,000 a year, to maintain the system. As of April, there were only 4,067 network devices in CenterPoint’s service area, meaning the utility pays about $30.70 each year to maintain each device.

Centerpoint last year generated $9.6 billion in revenues and earned a $1.8 billion profit, according to its financial filings. CenterPoint officials did not respond to requests for comment.

Other utilities that are part of the Smart Meter consortium also complained to the Public Utility Commission that, up to now, the system hasn’t developed. All told, Texas has 7.3 million meters connected to Smart Meter Texas, but less than 1 percent are using the networking functions to track real-time prices and consumption, according to the testimony of Donny R. Helm, director of technology strategy and architecture for the state’s largest utility Oncor Electric Delivery Co. in Dallas.

The isssue was resolved recently through a settlement agreement that limits on-demand readings to twice an hour that Smart Meter Texas must provide customers. The price of power changes every 15 minutes, so a twice an hour reading may miss some price spikes.

The Public Utility Commission signed off on the deal, and so did several other groups including several retail electricity providers and the Office of Public Utility Counsel which represents residential customers and small businesses.

Michele Gregg, spokeswoman for the Public Utility Counsel, testified in December that the consumer advocate supported the change because widespread use of the networks never materialized. Catherine Webking, an Austin lawyer who represents the Texas Energy Association for Marketers, a group of retail electric providers, said she believes the deal was a reasonable resolution of providing the benefits of Smart Meter Texas while not incurring too much cost.

But Griddy, an electricity provider that offers customers the opportunity to pay wholesale power prices, which also issued a plea to customers during a price surge, said the state hasn’t given the smart-meter networks a chance and could miss out on its potential. Griddy was counting on the continued adoption of real time pricing as the next step for customers wanting to control their electricity costs.

Right now, Griddy sends out price alerts from the grid operator Electric Reliability Council of Texas so businesses like hotels can run washers and dryers when electricity prices are cheapest. But the company was counting on a smart-meter program that would allow customers to track wholesale prices and manage consumption themselves, making Griddy’s offerings attractive to more people.

Wholesale prices are generally cheaper than retail prices, but they can fluctuate widely, especially when the Texas power grid faces another crisis during extreme weather. Last year, wholesale prices averaged less than 3 cents per kilowatt hour, much lower than than retail rates that now are running above 11 cents, but they can spike at times of high demand to as much as $9 a kilowatt hour.

What customers want is to be able to use energy when it’s cheapest, said Greg Craig, Griddy’s CEO, and they want to do it automatically. They want to be able to program their thermostat so that if the price rises they can shut off their air conditioning and if the price falls, they can charge their electric-powered vehicle.

Griddy customers may still save money even without real time data, he said. But they won’t be able to see their usage in real time or see how much they’re spending.

“The big utilities have big investments in the existing way and going to real time and more transparency isn’t really in their best interest,” said Craig.

Electricity is civilization": Winter looms over Ukraine battlefront

Ukraine Power Grid Restoration accelerates across liberated Kharkiv, restoring electricity, heat, and water amid missile and drone strikes, demining operations, blackouts, and winterization efforts, showcasing resilience, emergency repairs, and critical infrastructure recovery.

 

Key Points

Ukraine's rapid push to repair war-damaged grids, restore heat and water, and stabilize key services before winter.

✅ Priority repairs restore electricity and water in liberated Kharkiv.

✅ Crews de-mine lines and work under shelling, drones, and missiles.

✅ Winterization adds generators, mobile stoves, and large firewood supplies.

 

On the freshly liberated battlefields of northeast Ukraine, a pile of smashed glass windows outside one Soviet-era block of apartments attests to the violence of six months of Russian occupation, and of Ukraine’s sweeping recent military advances.

Indoors, in cramped apartments, residents lived in the dark for weeks on end.

Now, with a hard winter looming, they marvel at the speed and urgency with which Ukrainian officials have restored another key ingredient to their survival: electric power, a critical effort to keep the lights on this winter across communities.

Among those things governments strive to provide are security, opportunity, and minimal comfort. With winter approaching, and Russia targeting Ukraine’s infrastructure, add to that list heat and light, even as Russia hammers power plants nationwide. It’s requiring a concerted effort.

“Thank God it works! Electricity is civilization – it is everything,” says Antonina Krasnokutska, a retired medical worker, looking affectionately at the lightbulb that came on the day before, and now burns again in her tiny spotless kitchen.

“Without electricity there is no TV, no news, no clothes washing, no charging the phone,” says Ms. Krasnokutska, her gray hair pulled back and a small crucifix around her neck.

“Before, it was like living in the Stone Age,” says her grown son, Serhii Krasnokutskyi, who is more than a head taller. “As soon as it got dark, everyone would go to sleep.”

He shows a picture on his phone from a few days earlier, of a tangle of phone and computer charging cables – including his – plugged in at a local shop with a generator.

“We are very grateful for the people who repaired this electricity, even with shelling continuing,” he says. “They have a very complicated job.”

Indeed, although a lack of power might have been a novel inconvenience during the warm summer season, it increasingly has become a matter of great urgency for Ukrainian citizens and officials.

Coping through Ukraine’s winter with dignity and any degree of security will require courage and perseverance, as the severity and suffering that the season can bring here are being weaponized by Russia, as it seeks to compensate for a string of battlefield losses.

In recent days, Russian attacks have specifically targeted Ukraine’s electrical and other civilian infrastructure – all with the apparent aim of making this winter as hard as possible for Ukrainians, even as Moscow employs other measures to spread the hardship across Europe, while Ukraine helps Spain amid blackouts through grid support.

Ukrainian President Volodymyr Zelenskyy said Monday that Russian barrages across the country with missiles and Iran-supplied kamikaze drones had destroyed 30% of Ukraine’s power stations in the previous eight days, including strikes on western Ukraine that caused outages. Thousands of towns have been left without electricity.

Kharkiv’s challenges
Emblematic of the national challenge is the one facing officials in the northeast Kharkiv region, where Ukraine recaptured more than 3,000 square miles in a September counteroffensive. Ukrainian forces are still making gains on that front, as well as in the south toward Kherson, where Wednesday Russia started evacuating civilians from the first major city it occupied, after launching its three-pronged invasion last February.

Across the Kharkiv region, Ukrainians are stockpiling as much wood, fuel, and food as possible while they still can, and adopting new energy solutions as they prepare, from sources as diverse as the floorboards of destroyed schools and the pine forests in Izium, which are pockmarked with abandoned Russian trenches adjacent to a mass burial site.

“Of course, we have this race against time,” says Serhii Mahdysyuk, the Kharkiv regional director in charge of housing, services, fuel, and energy. “Unfortunately, we probably stand in front of the biggest challenge in Ukraine.”

That is not only because of the scale of liberated territory, he says, but also because the Kharkiv region shares a long border with Russia, as well as with the Russian-controlled areas of the eastern Donbas.

“It’s a great mixture of all threats, and we are sure that shelling and bombings will continue, but we are ready for this,” says Mr. Mahdysyuk. “We know our weak spots that Russia can destroy, but we are prepared for what to do in these situations.”

Ukraine’s battlefield gains have meant a surging need to pick up the pieces after Russian occupation, even as electricity reserves are holding if no new strikes occur, to ensure habitable conditions as more and more surviving residents require services, and as others return to scenes of devastation.

Restoring electricity is the top priority, amid shifting international assistance such as the end of U.S. grid support, because that often restarts running water, too, says Mr. Mahdysyuk. But before that, the area beneath broken power lines must be de-mined.

Indeed, members of an electricity team reconnecting cables on the outskirts of Balakliia – one of the first towns to see power restored, at the end of September – say they lost two fellow workers in the previous two weeks. One died after stepping on an anti-personnel mine, another when his vehicle hit an anti-tank device.

Ukrainian electricity workers restore power lines damaged during six months of Russian military occupation in Balakliia, Ukraine, Sept. 29, 2022. Ukrainians in liberated territory say the restoration of the electrical grid, and with it often the water supply, is a return to civilization.
“For now, our biggest problem is mines,” says the team leader, who gave the name Andrii. “It’s fine within the cities, but in the fields it’s a disaster because it’s very difficult to see them. There is a lot of [them] around here – it will take years and years to get rid of.”

Yet officials only have a few weeks to execute plans to provide for hundreds of thousands of residents in this region, in their various states of need and distress. Some 50 field kitchens capable of feeding 200 to 300 people each have been ordered. Another 1,000 mobile stoves are on their way.

And authorities will provide nearly 200,000 cubic yards of firewood for those who have no access to it, and may have no other means of keeping warm – or where shelling continues to disrupt repairs, says Mr. Mahdysyuk.

“The level of opportunity and resources we have is not the same as the level of destruction,” he says. People in districts and buildings too destroyed to have services restored soon, such as in Saltivka in Kharkiv city, may be moved.

Hydro One: No cut in peak hydro rates yet for self-isolating customers

Hydro One COVID-19 Rate Relief responds to time-of-use pricing, peak rates, and Ontario Energy Board rules as residents stay home, offering a Pandemic Relief Fund, flexible payments, and support for electricity bills amid off-peak adjustments.

 

Key Points

Hydro One's COVID-19 rate relief includes payment flexibility and hardship aid to ease time-of-use bill burdens.

✅ Advocates flexibility on time-of-use and peak rate impacts

✅ Pandemic Relief Fund offers aid and payment options

✅ OEB sets prices; utilities relay concerns and support

 

Hydro One says it is listening to requests by self-isolating residents for reduced kilowatt hour peak rates during the day when most people are home riding out the COVID-19 pandemic.

Peak rates of 20.8 cents per kw/h are twice as high from 7 a.m. to 7 p.m. – except weekends – than off-peak rates of 10.1 cents per kw/h and set by the Ontario Energy Board and not electricity providers such as Hydro One and Elexicon (formerly Veridian).

Frustrated electrical customers have signed their John Henry’s more than 50,000 times to a change.org petition demanding Hydro One temporarily slash rates for those already struggling with work closures and loss of income amid concerns about a potential recovery rate that could raise bills.

Alex Stewart, media relations spokesman for Hydro One, said the corporation is working toward a solution.

“While we are regulated to adhere to time-of-use pricing by the Ontario Energy Board, we’ve heard the concerns about time-of-use pricing and the idea of a fixed COVID-19 hydro rate as many of our customers will stay home to stop the spread of COVID-19,” Stewart told The Intelligencer.

“We continue to advocate for greater choice during this difficult time and are working with everyone in the electricity sector to ensure our customers are heard.”

Stewart said the electricity provider is reaching out to customers to help them during a difficult self-isolating and social distancing period in other ways to bring financial relief.

For example, new hardship measures are now in play by Hydro One to give customers some relief from ballooning electricity bills.

“This is a difficult time for everyone. Hydro One has launched a new Pandemic Relief Fund to support customers affected by the novel coronavirus COVID-19. As part of our commitment to customers, we will offer financial assistance, as well as increased payment flexibility, to customers experiencing hardship,” Stewart said.

“Hydro One is also extending its Winter Relief program to halt disconnections and reconnections to customers experiencing hardship during the coldest months of the year. This is about doing the right thing and offering flexibility to our customers so they have peace of mind and can concentrate on what matters most – keeping their loved ones safe.”

Stewart said customers having difficult times can visit the company’s website for more details at www.HydroOne.com/ReliefFund.

Elexicon Energy, meanwhile, said earlier the former Veridian company is passing along concerns to the OEB but otherwise can’t lower the rates unless directed to do so, as occurred when the province set off-peak pricing temporarily.

Chris Mace, Elexicon corporate communications spokesperson, said, “We don’t have the authority to do that.

“The Ontario Energy Board sets the energy prices. This is in the Ministry of Energy’s hands. We at Elexicon, along with other local distribution companies (LDC), have shared this feedback with the ministry and OEB to come up with some sort of solution or alternative. But this is out of our hands. We can’t shift anything.”

He suggested residents can shift the use of higher-drawing electrical appliances to early morning before 7 or in the evening after 7 p.m. when ultra-low overnight rates may apply.

Families may want to be “mindful whether it be cooking or laundry and so on and holding off on doing those until off-peak hours take effect. We are hearing customers and we have passed along those concerns to the ministry and the OEB.”

Hydro One power tips

Certain electrical uses in the home consumer more power than others, as reflected in Ontario’s electricity cost allocation approach:

62 per cent goes to space heating
19 per cent goes to water heaters
13 per cent goes to appliances
2 per cent goes to space cooling

Bruce Power cranking out more electricity after upgrade

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.
