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.

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

U.S. Announces $28 Million To Advance And Deploy Hydropower Technology

DOE Hydropower Funding advances clean energy R&D, pumped storage hydropower, retrofits for non-powered dams, and fleet modernization under the Bipartisan Infrastructure Law and Inflation Reduction Act, boosting long-duration energy storage, licensing studies, and sustainability engagement.

 

Key Points

A $28M DOE initiative supporting hydropower R&D, pumped storage, retrofits, and stakeholder sustainability efforts.

✅ Funds retrofits for non-powered dams, expanding low-impact supply

✅ Backs studies to license new pumped storage facilities

✅ Engages stakeholders on modernization and environmental impacts

 

The U.S. Department of Energy (DOE) today announced more than $28 million across three funding opportunities to support research and development projects that will advance and preserve hydropower as a critical source of clean energy. Funded through President Biden’s Bipartisan Infrastructure Law, this funding will support the expansion of low-impact hydropower (such as retrofits for dams that do not produce power) and pumped storage hydropower, the development of new pumped storage hydropower facilities, and engagement with key voices on issues like hydropower fleet modernization, sustainability, and environmental impacts. President Biden’s Inflation Reduction Act also includes a standalone tax credit for energy storage, which will further enhance the economic attractiveness of pumped storage hydropower. Hydropower will be a key clean energy source in transitioning away from fossil fuels and meeting President Biden’s goals of 100% carbon pollution free electricity by 2035 through a clean electricity standard policy pathway and a net-zero carbon economy by 2050.

“Hydropower has long provided Americans with significant, reliable energy, which will now play a crucial role in achieving energy independence and protecting the climate,” said U.S. Secretary of Energy Jennifer M. Granholm. “President Biden’s Agenda is funding critical innovations to capitalize on the promise of hydropower and ensure communities have a say in building America’s clean energy future, including efforts to revitalize coal communities through clean projects.” 

Hydropower accounts for 31.5% of U.S. renewable electricity generation and about 6.3% of total U.S. electricity generation, with complementary programs to bolster energy security for rural communities supporting grid resilience, while pumped storage hydropower accounts for 93% of U.S. utility-scale energy storage, ensuring power is available when homes and businesses need it, even as the aging U.S. power grid poses challenges to renewable integration.  

The funding opportunities include, as part of broader clean energy funding initiatives, the following: 

  • Advancing the sustainable development of hydropower and pumped storage hydropower by encouraging innovative solutions to retrofit non-powered dams, the development and testing of technologies that mitigate challenges to pumped storage hydropower deployment, as well as opportunities for organizations not extensively engaged with DOE’s Water Power Technologies Office to support hydropower research and development. (Funding amount: $14.5 million) 
  • Supporting studies that facilitate the FERC licensing process and eventual construction and commissioning of new pumped storage hydropower facilities to facilitate the long-duration storage of intermittent renewable electricity. (Funding amount: $10 million)
  • Uplifting the efforts of diverse hydropower stakeholders to discuss and find paths forward on topics that include U.S. hydropower fleet modernization, hydropower system sustainability, and hydropower facilities’ environmental impact. (Funding amount: $4 million)

Macron: France, Germany to provide each other with gas, electricity, to weather crisis

France-Germany Energy Solidarity underscores EU energy crisis cooperation: gas supply swaps, electricity imports, price cap talks, and curbs on speculation as Russian pipeline flows halt and winter demand rises across the bloc.

 

Key Points

A pact where France sends gas to Germany as Germany supplies power, bolstering EU cooperation and winter security.

✅ Gas to Germany; power to France amid nuclear outages.

✅ EU price cap, anti-speculation, joint gas purchasing.

✅ No new Spain-France pipeline unless case improves.

 

France will send gas to Germany if needed while Germany stands ready to provide it with electricity, President Emmanuel Macron said on Monday, saying this showcased European solidarity in the face of the energy crisis stemming from the war in Ukraine, which many view as a wake-up call to ditch fossil fuels across the bloc.

European gas prices surged, share prices slid and the euro sank on Monday after Russia stopped pumping gas via a major supply route, and Germany's 200 billion euro package sought to cushion the blow, in another warning to the 27-nation EU as it scrambled to respond to the crisis ahead of winter. read more

"Germany needs our gas and we need power from the rest of Europe, notably Germany," France's president told a news conference as EU electricity reform remains under debate following a phone call with German Chancellor Olaf Scholz.

The necessary connections for France to deliver gas to Germany when needed would be finalised in the coming weeks, he said, adding that France, which had long been a net exporter of electricity, will need help from its neighbours because of technical problems its nuclear plants face. read more

Macron, however, said that he did not understand demand for a third gas link between France and Spain, rejecting calls to increase capacity with a new pipeline.

He added he was open to changing his mind on that point, especially as Germany's utility troubles deepen, should Scholz or Prime Minister Pedro Sanchez argue convincingly for it.

Ahead of a meeting on Friday of EU energy ministers, Macron said France was in favour of buying gas at a European rather than a national level, as emergency electricity measures are weighed, and called for European Union measures to control energy prices.

He said it was necessary to act against speculation on energy prices at EU level, as the EU outlines possible gas price cap strategies for discussion, and also said France was in favour of putting a cap on the price of pipeline Russian gas.

Macron also repeated calls for all to turn down air conditioners when it's hot and to limit heating to 19 degrees Celsius this winter, noting that rolling back electricity prices is tougher than it appears this year.

"Everyone has to do their bit," he said.

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.

IEC reaches settlement on Palestinian electricity debt

IEC-PETL Electricity Agreement streamlines grid management, debt settlement, and bank guarantees, shifting power supply, transmission, and distribution to PETL via IEC-built sub-stations, bolstering energy cooperation, utility billing, and payment assurance in PA areas.

 

Key Points

A 15-year deal transferring PA grid operations to PETL, settling legacy debt, and securing payments with bank guarantees.

✅ NIS 915 million repaid in 48 installments.

✅ PETL assumes distribution, O&M, and sub-station ownership.

✅ 15-year, NIS 2.8b per year supply and services contract.

 

The Palestinian Authority will pay Israel Electric NIS 915 million and take over management of its grid through Palestinian electricity supplier PETL.

The Israel Electric Corporation (IEC) (TASE: ELEC.B22) and Palestinian electricity supplier PETL have signed a draft commercial agreement under which the Palestinian Authority's (PA) debt of almost NIS 1 billion will be repaid. The agreement also transfers actual management of the supply of electricity to Palestinian customers from IEC to the Palestinian electricity authority, enabling consideration of distributed solutions such as a virtual power plant program in future planning.

Up until now, the IEC was unable to actually collect debts for electricity from Palestinian customers, because the connection with them was through the PA. Responsibility for collection will now be exclusively in Palestinian hands, with the PA providing hundreds of millions of shekels in bank guarantees for future debts. The agreement, which is valid for 15 years, amounts to an estimated NIS 2.8 billion a year, as of now.

IEC will sell electricity and related services to PETL through four high-tension sub-stations built by IEC for PETL and through high and low-tension connection points, similar to large interconnector projects like the Lake Erie Connector, for the purpose of distribution and supply of the electricity by PETL or an entity on its behalf to consumers in PA territory. PETL will have sole operational and maintenance responsibility for distribution and supply and ownership of the four sub-stations.

 

NIS 915 million in 48 payments

According to the IEC announcement, the settlement was reached following negotiations following the signing of an agreement in principle in September 2016 by the minister of finance, the government coordinator of activities in the territories, and the Palestinian minister for civilian affairs. The parties reached commercial understandings yesterday that made possible today's signing of the first commercial document of its kind regulating commercial relations - the sales of electricity - between the parties. The agreement will go into effect after it is approved by the IEC board of directors, the Public Utilities Authority (electricity), reflecting regulatory oversight akin to Ontario industrial electricity pricing consultations, and the IDF Chief Electrical Staff Officer. Representatives of IEC, the Ministry of Finance, the Public Utilities Authority (electricity), the government coordinator of activities in the territories, the civilian authority, the PA government, and PETL took part in the negotiations.

The agreement also settles the PA's historical debt to IEC. The PA will begin payment of NIS 915 million in debt for consumption of electricity before September 2016 to IEC Jerusalem District Ltd. in 48 equal installments after the final signing, as stipulated in the agreement in principle signed by the Israeli government and the PA on September 13, 2016.

The PA's debt for electricity amounted to almost NIS 2 billion in 2016. The initial spadework for the current debt settlement was accomplished in that year, after the parties reached understandings on writing off NIS 500 million of the Palestinian debt. The PA paid NIS 600 million in October 2016, and the remainder will be paid now.

It was also reported that an arrangement of securities and guarantees to ensure payment to IEC under the agreement had been settled, including the past debt. IEC will obtain a bank guarantee and a PA guarantee, in addition to the existing collection mechanisms at the company's disposal.

Minister of Finance Moshe Kahlon said, "Signing the commercial agreement is a historic step completing the agreement signed by the governments in September 2016. Strengthening economic cooperation between Israel and the PA is above all an Israeli security interest. The agreement will ensure future payments to the IEC and reinforce its financial position. I congratulate the negotiating teams for the completion of their task."

Minister of National Infrastructure, Energy, and Water Resources Dr. Yuval Steinitz said, "In my meeting last year with Palestinian Prime Minister Rami Hamdallah in Jenin, we agreed that it was necessary to settle the debt and formalize relations between IEC and the PA. The settlement signed today is a breakthrough, both in the measures for payment of the Palestinian debt to IEC and Israel and in arranging future relations to prevent more debts from emerging in the future. With the signing of the agreement, we will be able to make progress with the Palestinians in developing a modern electrical grid, aligning with regional initiatives like the Cyprus electricity highway, according to the model of the sub-station we inaugurated in Jenin."

IEC chairperson Yiftah Ron Tal said, "This is a historic event. In this agreement, IEC is correcting for the first time a historical distortion of accumulated debt without guarantees, ability to collect it, or control over the amount of debt. This anchor agreement not only constitutes an unprecedented financial achievement; it also constitutes an important milestone in regulating electricity commercial relations between the Israeli and Palestinian electric companies, comparable to cross-border efforts such as the Ireland-France interconnector in Europe."

Sudbury Hydro crews aim to reconnect service after storm

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."

Monday's storm caused massive property damage across the city, particularly in New Sudbury. (Benjamin Aubé/CBC)

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."
