Canada Faces Critical Crunch in Electrical Supply

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

India spot electricity prices surged on Q3 demand, lifting power tariffs in the spot market as discoms scrambled for supply; Sembcorp SGPL boosted PLF and short-term PPA realizations, benefiting from INR per kWh peaks.

Key Points

India spot electricity prices hit Q3 records amid demand spikes, lifting tariffs and aiding Sembcorp SGPL via PLF gains.

✅ Record 10.6 cents/kWh average; 15-minute peak 20.7 cents/kWh

✅ SGPL shifted output to short-term PPA at 7.3 cents/kWh

✅ PLF ramped above 90%, cutting core losses by 30-40%

Electricity prices in India, now the third-largest electricity producer globally, bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3.

A jolt in Indian spot electricity prices could save Sembcorp Industries' Indian business from further losses, even though demand has occasionally slumped in recent years, UOB Kay Hian said.

The firm said spot electricity prices in India bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3 and even hit a 15-minute peak of 20.7 cents/kWh (9.9/kWh). The spike was due to a power supply crunch on higher electricity demand from power distribution companies, alongside higher imported coal volumes as domestic supplies shrank.

As an effect, Sembcorp Industries' Sembcorp Gayatri Power Limited's (SGPL) losses of $26m in Q1 and $29m in Q2 could narrow down by as much as 30-40%.

On a net basis, SGPL will recognise a significantly higher electricity tariff in 3Q17. By tactically shutting down its Unit #3 for maintenance, Unit #4 effectively had its generation contracted out at the higher short-term PPA tariff of around 7.3 cents/kWh (Rs3.5/kWh).

SGPL also capitalised on the price spike in 3Q17 as it ramped up its plant load factor (PLF) to more than 90%.

“On the back of this, coupled with the effects of reduced finance costs, we expect SGPL’s 3Q17 quarterly core loss to shrink by 30-40% from previous quarters,” UOB Kay Hian said.

Whilst electricity prices have corrected to 7.1 cents/kWh (INR3.4/kWh), the firm said it could still remain elevated on structural factors, even as coal and electricity shortages ease nationwide.

Sembcorp Industries' India operations brought in a robust performance for Q3. PLF for Thermal Powertech Corporation India Limited (TPCIL) hit 91%, whilst it reached 73% for SGPL, echoing the broader trend of thermal PLF up across the sector.

WA $600 Electricity Credit supports households with power bills as a budget stimulus, delivering an automatic rebate via Synergy and Horizon, funded by the Bell Group settlement to aid COVID-19 recovery and local spending.

Key Points

A one-off $600 power bill credit for all Synergy and Horizon residential accounts, funded by the Bell Group settlement.

✅ Automatic, not means-tested; applied to Synergy and Horizon accounts.

✅ Can offset upcoming bills or carry forward to future statements.

✅ Funded by Bell Group payout; aims to ease cost-of-living pressures.

Washington Premier Mark McGowan has announced more than a million households will receive a $600 electricity credit on their electricity account before their next bill.

The $650 million measure will form part of Thursday's pre-election state budget, similar to legislation to lower electricity rates in other jurisdictions, which has been delayed since May because of the pandemic and will help deflect criticism by the opposition that Labor hasn't done enough to stimulate WA's economy.

Mr McGowan made the announcement on Sunday while visiting a family in the electorate of Bicton.

"Here in WA, our state is in the best possible position as we continue our strong recovery from COVID-19, but times are still tough for many West Australians, and there is always more work to do," he said.

"[The credit] will mean WA families have a bit of extra money available in the lead up to Christmas.

"But I have a request, if this credit means you can spend some extra money, use it to support our local WA businesses."

The electricity bill credit will be automatically applied to every Synergy or Horizon residential account from Sunday, echoing moves such as reconnections for nonpayment by Hydro One in Canada.

It can be applied to future bills and will not be means tested.

"The $600 credit is fully funded through the recent Bell Group settlement, for the losses incurred in the Bell Group collapse in the early 1990s," Mr McGowan said.

"It made sense that these funds go straight back to Western Australians."

In September, the liquidator for the Bell Group and its finance arm distributed funds to its five major creditors, including $670 million to the WA government. The payment marked the close of the 30-year battle to recover taxpayer funds squandered during the WA Inc era of state politics.

The payout is the result of litigation stemming from the 1988 partnership between then Labor government and entrepreneur Alan Bond in acquiring major interests in Robert Holmes à Court’s failing Bell Group, following the 1987 stock market crash.

WA shadow minister for cost of living, Tony Krsticevic, said the $600 credit was returning money back into West Australian's pockets from "WA Labor's darkest days".

“This is taxpayers’ money out of a levy which was brought in to pay for Labor’s scandalous WA Inc losses of $450 million in the 1980s,” he said.

“This money should be returned to West Australians.

“WA families are in desperate need of it because they are struggling under cost of living increases of $850 every year since 2017 under WA Labor, amid concerns elsewhere that an electricity recovery rate could lead to higher hydro bills.

“But they need more than just a one-off payment. These $850 cost of living increases are an on-going burden.”

Prior to the onset of the coronavirus pandemic, the opposition believed it was gaining traction by attacking the government's increases to fees and charges in its first three budgets, and by urging an electricity market overhaul to favor consumers.

Last year, Labor increased household fees and charges by $127.77, which came on top of increases over the prior two budgets, as other jurisdictions faced hydro rate increases of around 3 per cent.

According the state's annual report on its finances released in September, the $2.6 billion budget surplus forecast in the at the end of 2019 had been reduced by $920 million to $1.7 billion despite the impact of the coronavirus.

But total public sector net debt was at $35.4 billion, down from the $36.1 billion revision at the end of 2019 in the mid-year review.

U.S. Offshore Wind Capacity is set to exceed 1 GW by 2024, driven by BOEM approvals, federal leases, and resilient supply chains, with eastern states scaling renewable energy, turbines, and content despite COVID-19 disruptions.

Key Points

Projected gigawatt-scale offshore wind growth enabled by BOEM approvals, federal leases, and East Coast state demand.

✅ 17+ GW leased; only 1,870 MW in announced first phases.

✅ BOEM approvals are critical to reach >1 GW by 2024.

✅ Local supply chains mitigate COVID-19 impacts and lower costs.

Offshore wind in the U.S. will exceed 1 GW of capacity by 2024 and add more than 1 GW annually by 2027, a trajectory consistent with U.S. offshore wind power trends, according to a report released last week by Navigant Research.

The report calculated over 17 GW of offshore state and federal leases for wind production, reflecting forecasts that $1 trillion offshore wind market growth is possible. However, the owners of those leases have only announced first phase plans for 1,870 MW of capacity, leaving much of the projects in early stages with significant room to grow, according to senior research analyst Jesse Broehl.

The Business Network for Offshore Wind (BNOW) believes it is possible to hit 1 GW by 2023-24, according to CEO Liz Burdock. While the economy has taken a hit from the coronavirus pandemic, she said the offshore wind industry can continue growing as "the supply chain from Asia and Europe regains speed this summer, and the administration starts clearing" plans of construction.

BNOW is concerned with the economic hardship imposed on secondary and tertiary U.S. suppliers due to the global spread of COVID-19.

Offshore wind has been touted by many eastern states and governors as an opportunity to create jobs, with U.S. wind employment expected to expand, according to industry forecasts. Analysts see the growing momentum of projects as a way to further lower costs by creating a local supply chain, which could be jeopardized by a long-term shutdown and recession.

"The federal government must act now — today, not in December — and approve project construction and operation plans," a recent BNOW report said. Approving any of the seven projects before BOEM, which has recently received new lease requests, currently would allow small businesses to get to work "following the containment of the coronavirus," but approval of the projects next year "may be too late to keep them solvent."

The prospects for maintaining momentum in the industry falls largely to the Department of the Interior's Bureau of Ocean Energy Management (BOEM). The industry cannot hit the 1 GW milestone without project approvals by BOEM, which is revising processes to analyze federal permit applications in the context of "greater build out of offshore wind capacity," according to its website.

"It is heavily dependent on the project approval success," Burdock told Utility Dive.

Currently, seven projects are awaiting determinations from BOEM on their construction operation plans in Massachusetts, New York, where a major offshore wind farm was recently approved, New Jersey and Maryland, with more to be added soon, a BNOW spokesperson told Utility Dive.

To date, only one project has received BOEM approval for development in federal waters, a 12 MW pilot by Dominion Energy and Ørsted in Virginia. The two-turbine project is a stepping stone to a commercial-scale 2.6 GW project the companies say could begin installation as soon as 2024, and gave the developers experience with the permitting process.

In the U.S., developers have the capacity to develop 16.9 GW of offshore wind in federal U.S. lease areas, even as wind power's share of the electricity mix surges nationwide, Broehl told Utility Dive, but much of that is in early stages. The Navigant report did not address any impacts of coronavirus on offshore wind, he said.

Although Massachusetts has legislation in place to require utilities to purchase 1.6 GW of wind power by 2026, and several other projects are in early development stages, Navigant expects the first large offshore wind projects in the U.S. (exceeding 200 MW) will come online in 2022 or later, and the first projects with 400 MW or more capacity are likely to be built by 2024-2025, and lessons from the U.K.'s experience could help accelerate timelines. The U.S. would add about 1.2 GW in 2027, Broehl said.

The federal leasing activities along with the involvement from Eastern states and utilities "virtually guarantees that a large offshore wind market is going to take off in the U.S.," Broehl said.

Surkhan-Pul-e-Khumri Power Line links Uzbekistan and Afghanistan via a 260-kilometer transmission line, boosting electricity exports, grid reliability, and regional trade; ADB-backed financing could open Pakistan's energy market with 24 million kWh daily.

Key Points

A 260-km line to expand Uzbekistan power exports to Afghanistan, ADB-funded, with possible future links to Pakistan.

✅ 260 km Surkhan-Pul-e-Khumri transmission link

✅ +70% electricity exports; up to 24M kWh daily

✅ ADB $70M co-financing; $32M from Uzbekistan

Senior officials with Uzbekistan’s state-run power company have said work has begun on building power cables to Afghanistan that will enable them to increase exports by 70 per cent, echoing regional trends like Ukraine resuming electricity exports after grid repairs.

Uzbekenergo chief executive Ulugbek Mustafayev said in a press conference on March 24 that construction of the Afghan section of the 260-kilometer Surkhan-Pul-e-Khumri line will start in June.

The Asian Development Bank has pledged $70 million toward the final expected $150 million bill of the project. Another $32 million will come from Uzbekistan.

Mustafayev said the transmission line would give Uzbekistan the option of exporting up to 24 million kilowatt hours to Afghanistan daily, similar to Ukraine's electricity export resumption amid shifting regional demand.

“We could potentially even reach Pakistan’s energy market,” he said, noting broader regional ambitions like Iran's bid to be a power hub linking regional grids.

This project was given fresh impetus by Afghan President Ashraf Ghani’s visit to Tashkent in December, mirroring cross-border energy cooperation such as Iran-Iraq energy talks in the region. His Uzbek counterpart, Shavkat Mirziyoyev, had announced at the time that work was set to begin imminently on the line, which will run from the village of Surkhan in Uzbekistan’s Surkhandarya region to Pul-e-Khumri, a town in Afghanistan just south of Kunduz.

In January, Mirziyoyev issued a decree ordering that the rate for electricity deliveries to Afghanistan be dropped from $0.076 to $0.05 per kilowatt.

Mustafayev said up to 6 billion kilowatt hours of electricity could eventually be sent through the power lines. More than 60 billion kilowatt hours of electricity was produced in Uzbekistan in 2017.

According to Tulabai Kurbonov, an Uzbek journalist specializing in energy issues, the power line will enable the electrification of the the Hairatan-Mazar-i-Sharif railroad joining the two countries. Trains currently run on diesel. Switching over to electricity will help reduce the cost of transporting cargo.

There is some unhappiness, however, over the fact that Uzbekistan plans to sell power to Afghanistan when it suffers from significant shortages domestically and wider Central Asia electricity shortages persist.

"In the villages of the Ferghana Valley, especially in winter, people are suffering from a shortage of electricity,” said Munavvar Ibragimova, a reporter based in the Ferghana Valley. “You should not be selling electricity abroad before you can provide for your own population. What we clearly see here is the favoring of the state’s interests over those of the people.”
