Intel to install rooftop solar panels

Canada Critical Infrastructure Cyber Risks include state-sponsored actors probing the electricity grid and ICS/OT, ransomware on utilities, and espionage targeting smart cities, medical devices, and energy networks, pre-positioning for disruptive operations.

Key Points

Nation-state and criminal cyber risks to Canada's power, water, and OT/ICS, aiming to disrupt, steal data, or extort.

✅ State-sponsored probing of power grid and utilities

✅ OT/ICS exposure grows as systems connect to IT networks

✅ Ransomware, espionage, and pre-positioning for disruption

State-sponsored actors are "very likely" trying to shore up their cyber capabilities to attack Canada's critical infrastructure — such as the electricity supply, as underscored by the IEA net-zero electricity report indicating rising demand for clean power, to intimidate or to prepare for future online assaults, a new intelligence assessment warns.

"As physical infrastructure and processes continue to be connected to the internet, cyber threat activity has followed, leading to increasing risk to the functioning of machinery and the safety of Canadians," says a new national cyber threat assessment drafted by the Communications Security Establishment.

"We judge that state-sponsored actors are very likely attempting to develop the additional cyber capabilities required to disrupt the supply of electricity in Canada, even as cleaning up Canada's electricity remains critical for climate goals."

Today's report — the second from the agency's Canadian Centre for Cyber Security wing — looks at the major cyber threats to Canadians' physical safety and economic security.

The CSE does say in the report that while it's unlikely cyber threat actors would intentionally disrupt critical infrastructure — such as water and electricity supplies — to cause major damage or loss of life, they would target critical organizations "to collect information, pre-position for future activities, or as a form of intimidation."

The report said Russia-associated actors probed the networks of electricity utilities in the U.S. and Canada last year and Chinese state-sponsored cyber threat actors have targeted U.S. utility employees. Other countries have seen their industrial control systems targeted by Iranian hacking groups and North Korean malware was found in the IT networks of an Indian power plant, it said.

The threat grows as more critical infrastructure goes high-tech.

In the past, the operational technology (OT) used to control dams, boilers, electricity and pipeline operations has been largely immune to cyberattacks — but that's changing as manufacturers incorporate newer information technology in their systems and products and as the race to net-zero drives grid modernization, says the report.

That technology might make things easier and lower costs for utilities already facing debates over electricity prices in Alberta amid affordability concerns, but it comes with risks, said Scott Jones, the head of the cyber centre.

"So that means now it is a target, it is accessible and it's vulnerable. So what you could see is shutting off of transmission lines, you can see them opening circuit breakers, meaning electricity simply won't flow to our homes to our business," he told reporters Wednesday.

While the probability of such attacks remains low, Jones said the goal of Wednesday's briefing is to send out the early warnings.

"We're not trying to scare people. We're certainly not trying to scare people into going off grid by building a cabin in the woods. We're here to say, 'Let's tackle these now while they're still paper, while they're still a threat we're writing down.'"

Steve Waterhouse, a former cybersecurity officer for the Department of National Defence who now teaches at Université de Sherbrooke, said a saving grace for Canada could be the makeup of its electrical systems.

"Since in Canada, they're very centralized, it's easier to defend, and debates about bridging Alberta and B.C. electricity aim to strengthen resilience, while down in the States, they have multiple companies all around the place. So the weakest link is very hard to identify where it is, but the effect is a cascading effect across the country ... And it could impact Canada, just like we saw in the big Northeastern power outage, the blackout of 2003," he said.

"So that goes to say, we have to be prepared. And I believe most energy companies have been taking extra measures to protect and defend against these type of attacks, even as Canada points to nationwide climate success in electricity to meet emissions goals."

In the future, attacks targeting so-called smart cities and internet-connected devices, such as personal medical devices, could also put Canadians at risk, says the report. 

Earlier this year, for example, Health Canada warned the public that medical devices containing a particular Bluetooth chip — including pacemakers, blood glucose monitors and insulin pumps — are vulnerable to cyber attacks that could crash them.

The foreign signals intelligence agency also says that while state-sponsored programs in China, Russia, Iran and North Korea "almost certainly" pose the greatest state-sponsored cyber threats to Canadian individuals and organizations, many other states are rapidly developing their own cyber programs.

Waterhouse said he was glad to see the government agency call out the countries by name, representing a shift in approach in recent years.

"To tackle on and be ready to face a cyber-attack, you have to know your enemy," he said.

"You have to know what's vulnerable inside of your organization. You have to know how ... vulnerable it is against the threats that are out there."

Commercial espionage continues
State-sponsored actors will also continue their commercial espionage campaigns against Canadian businesses, academia and governments — even as calls to make Canada a post-COVID manufacturing hub grow — to steal Canadian intellectual property and proprietary information, says the CSE.

"We assess that these threat actors will almost certainly continue attempting to steal intellectual property related to combating COVID-19 to support their own domestic public health responses or to profit from its illegal reproduction by their own firms," says the "key judgments" section of the report.

"The threat of cyber espionage is almost certainly higher for Canadian organizations that operate abroad or work directly with foreign state-owned enterprises."

The CSE says such commercial espionage is happening already across multiple fields, including aviation, technology and AI, energy and biopharmaceuticals.

While state-sponsored cyber activity tends to offer the most sophisticated threats, CSE said that cybercrime continues to be the threat most likely to directly affect Canadians and Canadian organizations, through vectors like online scams and malware.

"We judge that ransomware directed against Canada will almost certainly continue to target large enterprises and critical infrastructure providers. These entities cannot tolerate sustained disruptions and are willing to pay up to millions of dollars to quickly restore their operations," says the report.

Cybercrime becoming more sophisticated 
According to the Canadian Anti-Fraud Centre, Canadians lost over $43 million to cybercrime last year. The CSE reported earlier this year that online thieves have been using the COVID-19 pandemic to trick Canadians into forking over their money — through scams like a phishing campaign that claimed to offer access to a Canada Emergency Response Benefit payment in exchange for the target's personal financial details.

Online foreign influence activities — a dominant theme in the CSE's last threat assessment briefing — continue and constitute "a new normal" in international affairs as adversaries seek to influence domestic and international political events, says the agency.

"We assess that, relative to some other countries, Canadians are lower-priority targets for online foreign influence activity," it said.

"However, Canada's media ecosystem is closely intertwined with that of the United States and other allies, which means that when their populations are targeted, Canadians become exposed to online influence as a type of collateral damage."

According to the agency's own definition, "almost certainly" means it is nearly 100 per cent certain in its analysis, while "very likely" means it is 80-90 per cent certain of its conclusions. The CSE says its analysis is based off of a mix of confidential and non-confidential intelligence and sources.

Power Grid Climate Resilience demands storm hardening, underground power lines, microgrids, batteries, and renewable energy as regulators and utilities confront climate change, sea level rise, and extreme weather to reduce outages and protect vulnerable communities.

Key Points

It is the grid capacity to resist and recover from climate hazards using buried lines, microgrids, and batteries.

✅ Underground lines reduce wind outages and wildfire ignition risk.

✅ Microgrids with solar and batteries sustain critical services.

✅ Regulators balance cost, resilience, equity, and reliability.

Every time a storm lashes the Carolina coast, the power lines on Tonye Gray’s street go down, cutting her lights and air conditioning. After Hurricane Florence in 2018, Gray went three days with no way to refrigerate medicine for her multiple sclerosis or pump the floodwater out of her basement.

What you need to know about the U.N. climate summit — and why it matters
“Florence was hell,” said Gray, 61, a marketing account manager and Wilmington native who finds herself increasingly frustrated by the city’s vulnerability.

“We’ve had storms long enough in Wilmington and this particular area that all power lines should have been underground by now. We know we’re going to get hit.”

Across the nation, severe weather fueled by climate change is pushing aging electrical systems past their limits, often with deadly results. Last year, amid increasing nationwide blackouts, the average American home endured more than eight hours without power, according to the U.S. Energy Information Administration — more than double the outage time five years ago.

This year alone, a wave of abnormally severe winter storms caused a disastrous power failure in Texas, leaving millions of homes in the dark, sometimes for days, and at least 200 dead. Power outages caused by Hurricane Ida contributed to at least 14 deaths in Louisiana, as some of the poorest parts of the state suffered through weeks of 90-degree heat without air conditioning.

As storms grow fiercer and more frequent, environmental groups are pushing states to completely reimagine the electrical grid, incorporating more grid-scale batteries, renewable energy sources and localized systems known as “microgrids,” which they say could reduce the incidence of wide-scale outages. Utility companies have proposed their own storm-proofing measures, including burying power lines underground.

But state regulators largely have rejected these ideas, citing pressure to keep energy rates affordable. Of $15.7 billion in grid improvements under consideration last year, regulators approved only $3.4 billion, according to a national survey by the NC Clean Energy Technology Center — about one-fifth, highlighting persistent vulnerabilities in the grid nationwide.

After a weather disaster, “everybody’s standing around saying, ‘Why didn’t you spend more to keep the lights on?’ ” Ted Thomas, chairman of the Arkansas Public Service Commission, said in an interview with The Washington Post. “But when you try to spend more when the system is working, it’s a tough sell.”

A major impediment is the failure by state regulators and the utility industry to consider the consequences of a more volatile climate — and to come up with better tools to prepare for it. For example, a Berkeley Lab study last year of outages caused by major weather events in six states found that neither state officials nor utility executives attempted to calculate the social and economic costs of longer and more frequent outages, such as food spoilage, business closures, supply chain disruptions and medical problems.

“There is no question that climatic changes are happening that directly affect the operation of the power grid,” said Justin Gundlach, a senior attorney at the Institute for Policy Integrity, a think tank at New York University Law School. “What you still haven’t seen … is a [state] commission saying: 'Isn’t climate the through line in all of this? Let’s examine it in an open-ended way. Let’s figure out where the information takes us and make some decisions.’ ”

In interviews, several state commissioners acknowledged that failure.

“Our electric grid was not built to handle the storms that are coming this next century,” said Tremaine L. Phillips, a commissioner on the Michigan Public Service Commission, which in August held an emergency meeting to discuss the problem of power outages. “We need to come up with a broader set of metrics in order to better understand the success of future improvements.”

Five disasters in four years
The need is especially urgent in North Carolina, where experts warn Atlantic grids and coastlines need a rethink as the state has declared a federal disaster from a hurricane or tropical storm five times in the past four years. Among them was Hurricane Florence, which brought torrential rain, catastrophic flooding and the state’s worst outage in over a decade in September 2018.

More than 1 million residents were left disconnected from refrigerators, air conditioners, ventilators and other essential machines, some for up to two weeks. Elderly residents dependent on oxygen were evacuated from nursing homes. Relief teams flew medical supplies to hospitals cut off by flooded roads. Desperate people facing closed stores and rotting food looted a Wilmington Family Dollar.

“I have PTSD from Hurricane Florence, not because of the actual storm but the aftermath,” said Evelyn Bryant, a community organizer who took part in the Wilmington response.

The storm reignited debate over a $13 billion proposal by Duke Energy, one of the largest power companies in the nation, to reinforce the state’s power grid. A few months earlier, the state had rejected Duke’s request for full repayment of those costs, determining that protecting the grid against weather is a normal part of doing business and not eligible for the type of reimbursement the company had sought.

After Florence, Duke offered a smaller, $2.5 billion plan, along with the argument that severe weather events are one of seven “megatrends” (including cyberthreats and population growth) that require greater investment, according to a PowerPoint presentation included in testimony to the state. The company owns the two largest utilities in North Carolina, Duke Energy Carolinas and Duke Energy Progress.

Vote Solar, a nonprofit climate advocacy group, objected to Duke’s plan, saying the utility had failed to study the risks of climate impacts. Duke’s flood maps, for example, had not been updated to reflect the latest projections for sea level rise, they said. In testimony, Vote Solar claimed Duke was using environmental trends to justify investments “it had already decided to pursue.”

The United States is one of the few countries where regulated utilities are usually guaranteed a rate of return on capital investments, even as studies show the U.S. experiences more blackouts than much of the developed world. That business model incentivizes spending regardless of how well it solves problems for customers and inspires skepticism. Ric O’Connell, executive director of GridLab, a nonprofit group that assists state and regional policymakers on electrical grid issues, said utilities in many states “are waving their hands and saying hurricanes” to justify spending that would do little to improve climate resilience.

In North Carolina, hurricanes convinced Republicans that climate change is real

Duke Energy spokesman Jeff Brooks acknowledged that the company had not conducted a climate risk study but pointed out that this type of analysis is still relatively new for the industry. He said Duke’s grid improvement plan “inherently was designed to think about future needs,” including reinforced substations with walls that rise several feet above the previous high watermark for flooding, and partly relied on federal flood maps to determine which stations are at most risk.

Brooks said Duke is not using weather events to justify routine projects, noting that the company had spent more than a year meeting with community stakeholders and using their feedback to make significant changes to its grid improvement plan.

This year, the North Carolina Utilities Commission finally approved a set of grid improvements that will cost customers $1.2 billion. But the commission reserved the right to deny Duke reimbursement of those costs if it cannot prove they are prudent and reasonable. The commission’s general counsel, Sam Watson, declined to discuss the decision, saying the commission can comment on specific cases only in public orders.

The utility is now burying power lines in “several neighborhoods across the state” that are most vulnerable to wide-scale outages, Brooks said. It is also fitting aboveground power lines with “self-healing” technology, a network of sensors that diverts electricity away from equipment failures to minimize the number of customers affected by an outage.

As part of a settlement with Vote Solar, Duke Energy last year agreed to work with state officials and local leaders to further evaluate the potential impacts of climate change, a process that Brooks said is expected to take two to three years.

High costs create hurdles
The debate in North Carolina is being echoed in states across the nation, where burying power lines has emerged as one of the most common proposals for insulating the grid from high winds, fires and flooding. But opponents have balked at the cost, which can run in the millions of dollars per mile.

In California, for example, Pacific Gas & Electric wants to bury 10,000 miles of power lines, both to make the grid more resilient and to reduce the risk of sparking wildfires. Its power equipment has contributed to multiple deadly wildfires in the past decade, including the 2018 Camp Fire that killed at least 85 people.

PG&E’s proposal has drawn scorn from critics, including San Jose Mayor Sam Liccardo, who say it would be too slow and expensive. But Patricia Poppe, the company’s CEO, told reporters that doing nothing would cost California even more in lost lives and property while struggling to keep the lights on during wildfires. The plan has yet to be submitted to the state, but Terrie Prosper, a spokeswoman for the California Public Utilities Commission, said the commission has supported underground lines as a wildfire mitigation strategy.

Another oft-floated solution is microgrids, small electrical systems that provide power to a single neighborhood, university or medical center. Most of the time, they are connected to a larger utility system. But in the event of an outage, microgrids can operate on their own, with the aid of solar energy stored in batteries.

In Florida, regulators recently approved a four-year microgrid pilot project, but the technology remains expensive and unproven. In Maryland, regulators in 2016 rejected a plan to spend about $16 million for two microgrids in Baltimore, in part because the local utility made no attempt to quantify “the tangible benefits to its customer base.”

Amid shut-off woes, a beacon of energy

In Texas, where officials have largely abandoned state regulation in favor of the free market, the results have been no more encouraging. Without requirements, as exist elsewhere, for building extra capacity for times of high demand or stress, the state was ill-equipped to handle an abnormal deep freeze in February that knocked out power to 4 million customers for days.

Since then, Berkshire Hathaway Energy and Starwood Energy Group each proposed spending $8 billion to build new power plants to provide backup capacity, with guaranteed returns on the investment of 9 percent, but the Texas legislature has not acted on either plan.

New York is one of the few states where regulators have assessed the risks of climate change and pushed utilities to invest in solutions. After 800,000 New Yorkers lost power for 10 days in 2012 in the wake of Hurricane Sandy, state regulators ordered utility giant Con Edison to evaluate the state’s vulnerability to weather events.

The resulting report, which estimated climate risks could cost the company as much as $5.2 billion by 2050, gave ConEd data to inform its investments in storm hardening measures, including new storm walls and submersible equipment in areas at risk of flooding.

Meanwhile, the New York Public Service Commission has aggressively enforced requirements that utility companies keep the lights on during big storms, fining utility providers nearly $190 million for violations including inadequate staffing during Tropical Storm Isaias in 2020.

“At the end of the day, we do not want New Yorkers to be at the mercy of outdated infrastructure,” said Rory M. Christian, who last month was appointed chair of the New York commission.

The price of inaction
In North Carolina, as Duke Energy slowly works to harden the grid, some are pursuing other means of fostering climate-resilient communities.

Beth Schrader, the recovery and resilience director for New Hanover County, which includes Wilmington, said some of the people who went the longest without power after Florence had no vehicles, no access to nearby grocery stores and no means of getting to relief centers set up around the city.

For example, Quanesha Mullins, a 37-year-old mother of three, went eight days without power in her housing project on Wilmington’s east side. Her family got by on food from the Red Cross and walked a mile to charge their phones at McDonald’s. With no air conditioning, they slept with the windows open in a neighborhood with a history of violent crime.

Schrader is working with researchers at the University of North Carolina in Charlotte to estimate the cost of helping people like Mullins. The researchers estimate that it would have cost about $572,000 to provide shelter, meals and emergency food stamp benefits to 100 families for two weeks, said Robert Cox, an engineering professor who researches power systems at UNC-Charlotte.

Such calculations could help spur local governments to do more to help vulnerable communities, for example by providing “resilience outposts” with backup power generators, heating or cooling rooms, Internet access and other resources, Schrader said. But they also are intended to show the costs of failing to shore up the grid.

“The regulators need to be moved along,” Cox said.

In the meantime, Tonye Gray finds herself worrying about what happens when the next storm hits. While Duke Energy says it is burying power lines in the most outage-prone areas, she has yet to see its yellow-vested crews turn up in her neighborhood.

“We feel,” she said, “that we’re at the end of the line.”

Western Lithium Supply Localization is accelerating as EV battery makers diversify from China, boosting lithium hydroxide sourcing in North America and Europe, amid Covid-19 disruptions and rising prices, with geothermal brines and local processing.

Key Points

An industry shift to source lithium and processing near EV hubs, reducing China reliance and supply chain risk.

✅ EV makers seek North American and European lithium hydroxide

✅ Prices rise amid Covid-19 and logistics constraints

✅ New extraction: geothermal and oilfield brine projects

The global outbreak of coronavirus will accelerate efforts by western carmakers to localise supplies of lithium for electric car batteries, according to US producer Livent.

The industry was keen to diversify away from China, which produces the bulk of the world’s lithium, a critical material for lithium-ion batteries, said Paul Graves, Livent’s chief executive.

“It’s a conversation that’s starting to happen that was not happening even six months ago,” especially in the US, the former Goldman Sachs banker added.

China produced about 79 per cent of the lithium hydroxide used in electric car batteries last year, according to consultancy CRU, a supply chain that has been disrupted by the virus outbreak and EV shortages in some markets.

Prices for lithium hydroxide rose 3.1 per cent last month, their first increase since May 2018, according to Benchmark Mineral Intelligence, due to the impact of the Covid-19 bug.

Chinese lithium producer Ganfeng Lithium, which supplies major carmakers from Tesla to Volkswagen, said it had raised prices by less than 10 per cent, due to higher production costs and logistical difficulties.

“We can get lithium from lots of places . . . is that really something we’re prepared to rely upon?” Mr Graves said. “People are going to relook at supply chains, including battery recycling initiatives that enhance resilience, and relook at their integrity . . . and they’re going to say is there something we need to do to change our supply chains to make them more shockproof?”

General Motors last week said it was looking to source battery minerals such as lithium and nickel from North America for its new range of electric cars that will use cells made in Ohio by South Korea’s LG Chem.

“Some of these critical minerals could be challenging to obtain; it’s not just cobalt you need to be concerned about but also battery-grade nickel and lithium as well,” said Andy Oury, a lead engineer for batteries at GM. “We’re doing all of this with an eye to sourcing as much of the raw material from North America as possible.”

However, George Heppel, an analyst at CRU, warned it would be difficult to compete with China on costs. “China is always going to be the most competitive place to buy battery raw materials. That’s not likely to change anytime soon,” he said.

Livent, which extracts lithium from brines in northern Argentina, is looking at extracting the mineral from geothermal resources in the US and also wants to build a processing plant in Europe.

The Philadelphia-based company is also working with Canadian start-up E3 Metals to extract lithium from brines in Alberta's oil and gasfields for new projects in Canada.

“We’ll look at doing more in the US and more in Europe,” said Mr Graves, underscoring evolving Canada-U.S. collaboration across EV supply chains.

Marine Renewables Canada Offshore Wind integrates marine renewables, tidal and wave energy, advancing clean electricity, low-carbon power, supply chain development, and regulatory alignment to scale offshore wind energy projects across Canada's coasts and global markets.

Key Points

An initiative to grow offshore wind using Canada's marine strengths, shared supply chains, and regulatory synergies.

✅ Leverages tidal and wave energy expertise for offshore wind

✅ Aligns supply chain, safety, and regulatory frameworks

✅ Supports low-carbon power and clean electricity goals

With a growing global effort to develop climate change solutions and increase renewable electricity production, including the UK offshore wind growth in recent years, along with Canada’s strengths in offshore and ocean sectors, Marine Renewables Canada has made a strategic decision to grow its focus by officially including offshore wind energy in its mandate.

Marine Renewables Canada plans to focus on similarities and synergies of the resources in order to advance the sector as a whole and ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

“Many of our members working on tidal energy and wave energy projects also have expertise that can service offshore wind projects both domestically and internationally,” says Tim Brownlow, Chair of Marine Renewables Canada. “For us, offshore wind is a natural fit and our involvement will help ensure that Canadian companies and researchers are gaining knowledge and opportunities in the offshore wind sector as it grows.”

Canada has the longest coastlines in the world, giving it huge potential for offshore wind energy development. In addition to the resource, Canada has significant capabilities from offshore and marine industries that can contribute to offshore wind energy projects. The global offshore wind market is estimated to grow by over 650% by 2030 and presents new opportunities for Canadian business.

“The federal government’s recent inclusion of offshore renewables in legislation, including a plan for regulating offshore wind developed by the government, and support for emerging renewable energy technologies are important steps toward building this industry,” says Elisa Obermann, executive director of Marine Renewables Canada. “There are still challenges to address before we’ll see offshore wind energy development in Canada, but we see a great opportunity to get more involved now, increase our experience, and help inform future development.”

Like wave and tidal energy, offshore wind projects operate in harsh marine environments and development presents many of the same challenges and benefits as it does for other marine renewable energy resources. Marine Renewables Canada has recognized that there is significant overlap between offshore wind and wave and tidal energy when it comes to the supply chain, regulatory issues, and the operating environment. The association plans to focus on similarities and synergies of the resources in order to advance the sector as a whole, leveraging Canada’s opportunity in the global electricity market to ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

Energy Transition Grid Reforms address transmission capacity, interconnection, congestion management, and flexibility markets, enabling renewable integration and grid stability while optimizing network charges and access in Australia, Ireland, and Great Britain.

Key Points

Measures to expand transmission, boost flexibility, and manage congestion for reliable, low-carbon electricity systems.

✅ Transmission upgrades and interconnectors ease congestion

✅ Flexible markets, DER, and storage bolster grid stability

✅ Evolving network charges and access incentivize siting

Electricity networks globally are experiencing significant increases in the volume of renewable capacity as countries seek to decarbonise their power sectors, even as clean energy's 'dirty secret' highlights integration trade-offs, without impacting the security of supply. The scale of this change is creating new challenges for power networks and those responsible for keeping the lights on.

The latest insight paper from Cornwall Insight – Market design amidst global energy transition – looks into this issue. It examines the outlook for transmission networks, and how legacy design and policies are supporting decarbonisation, aligning with IRENA findings on renewables and shaping the system. The paper focuses on three key markets; Australia, Ireland and Great Britain (GB).

Australia's main priority is to enhance transmission capacity and network efficiency; as concerns over excess solar risking blackouts grow in distribution networks, without this, the transmission system will be a barrier to growth for decentralised flexibility and renewables. In contrast, GB and Ireland benefit from interconnection with other national markets. This provides them with additional levers that can be pulled to manage system security and supply. However, they are still trying to hone and optimise network flexibility in light of steepening decarbonisation objectives.

Unsurprisingly, renewable energy resources have been growing in all three markets, with Ireland regarded as a leader in grid integration, with this expected to continue for the foreseeable future. Many of these projects are often located in places where network infrastructure is not as well developed, creating pressure on system operation as a result.

In all three markets, unit charges are rising, driven by a reduced charging base as decentralised energy grows quickly. This combination of changes is leading to network congestion, a challenge mirrored by the US grid overhaul for renewables underway, as transmission network development struggles to keep up, and flexibility markets are being optimised and changed.

In summary, reforms are on-going in each jurisdiction to accommodate the rapid physical transformation of the generation mix. Each has its objectives and tensions which are reflective of wider global reform programmes being undertaken in most developed, liberalised and decarbonising energy markets.

Gareth Miller, CEO of Cornwall Insight, said: “Despite differences in market design and characteristics, all three markets are grappling with similar issues, that comes from committing to deep decarbonisation. This includes the most appropriate methods for charging for networks, managing access to them and dealing with issues such as network congestion and constraint.

“In all three countries, renewable projects are often placed in isolated locations, as seen in Scotland where more pylons are needed to keep the lights on, away from the traditional infrastructure that is closer to demand. However, as renewable growth is set to continue, the networks will need to transition from being demand-centric to more supply orientated.

“Both system operators and stakeholders will need to continually evaluate their market structures and designs to alleviate issues surrounding locational congestion and grid stability. Each market is at very different stages in the process in trying to improve any problems implementing solutions to allow for higher efficiencies in renewable energy integration.

“It is uncertain whether any of the proposed changes will fundamentally resolve the issues that come with increased renewables on the system. However, despite marked differences, they certainly could all learn from each other and elements of their network arrangements, as well as from US decarbonisation strategies research.”

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.
