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.”

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

Key Points

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

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

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

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

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

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

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

West African Power Pool

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

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

Better ecological footprint

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

Global relevance

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

Saskatchewan COVID-19 economic impact: real-time data shows drops in electricity demand, oil well licensing, traffic and tickets, plus spikes in internet usage, government site visits, remote work, and alcohol wholesale volumes.

Key Points

COVID-19 reduced energy use, drilling and traffic, while pushing activity online; jobs, rents and sales show strain.

✅ Electricity demand down 6.7%; residential usage up

✅ Oil well license applications fell 15-fold in April

✅ Internet traffic up 16%-46%; wireless LTE up 34%

We’re only just beginning to grasp how COVID-19 has upended Saskatchewan’s economy, its government and all of our lives.

The numbers that usually make headlines — job losses, economic contraction, bankruptcies — are still well behind the pace of the virus and its toll.

But other numbers change more quickly. Saskatchewan people are using less power, and the power industry is adopting on-site staffing plans to ensure reliability as conditions evolve. We’re racking up fewer speeding tickets. And as new restrictions come, we’re clicking onto Saskatchewan.ca as much as 10,000 times per minute.

Here’s some data that provides a first glimpse into how much our province has changed in just six weeks.

Electricity use tends to rise and fall in tandem with the health of the economy, and the most recent data from SaskPower suggests businesses are powering down, while regional utilities such as Manitoba Hydro seek unpaid days off to trim costs.

Peak load requirements between March 15 and April 26 were 220 MW lower than during the same period in 2019, and elsewhere BC Hydro is posting COVID-19 updates at Site C as it manages project impacts. That’s a decrease of 6.7 per cent, with total load on April 29 at 2,551 MW. A megawatt is enough electricity to power about 1,000 homes.

Separate from pandemic impacts, an external investigation at Manitoba Hydro has drawn attention to workplace conduct issues.

But it’s not homes that are turning off the lights. SaskPower spokesman Joel Cherry said commercial and industrial usage is down, while residential demand is up, with household electricity bills rising as more people stay home.

The timing of power demand has also shifted, a pattern seen as residential electricity use rises during work-from-home routines. Peak load would usually come around 8 or 9 p.m. in April. Now it’s coming earlier, typically between 5 and 6 p.m.

Oil well applications fall 15-fold
Oil prices have cratered since late February, and producers in Saskatchewan have reacted by pulling back on drilling plans, while neighbouring Alberta provides transition support for coal workers amid broader energy shifts.

Applications for well licences fell from 242 in January to 203 in February (including nine potash and one helium operations), before dropping to 84 in March. April, the month benchmark oil prices went negative for one day, producers submitted just 15 applications.

That’s 15 times fewer than the 231 applications the Ministry of Energy and Resources received in April 2019.

Well licences are needed for drilling, operating, injecting, producing or exploring an oil and gas or potash well in the province.

There has been no clear trend in well abandonment, however. There were 176 applications for abandonment in March and 155 in April, roughly in line with figures from the year before.

SGI spokesman Tyler McMurchy believes the lower numbers might stem from a combination of lower traffic volumes during part of the month, possibly combined with a shift in police priorities. The March 2020 numbers are also well below January and February figures.

Indeed, the Ministry of Highways and infrastructure reported a 16 per cent decrease in average daily traffic last month compared to March 2019, through its traffic counts at 11 different spots on highways across the province.

In Regina, traffic counts at 16 locations dropped from a high of 2.1 million in the first week of March to a low of 1.3 million during the week of March 22. That’s a 44 per cent decrease.

Counts have gradually recovered to 1.6 million in the weeks since. The data was fairly consistent at all 16 spots, which are largely major intersections, though the city cautioned they may not be representative of Regina as a whole.

Tickets for cellphone use while driving also fell, dropping from 562 in February to 314 in March. McMurchy noted that distracted driving numbers in general have been falling since November as stiffer penalties were announced. Impaired driving tickets were up, by contrast, but still within a typical range.

Internet traffic shoots up 16 per cent, far more for rural high speed
You may be spending a lot more time on Netflix and Facebook in the age of social distancing, and SaskTel has noticed.

From late February to late April, SaskTel has seen “very significant increases in provincial data traffic.” DSL and fibre optic networks have handled a 16 per cent increase in traffic, while demand on the wireless LTE network is up 34 per cent.

Usage on the Fusion network up 46 per cent. That network serves rural areas that don’t have access to other high-speed options.

The specific reference dates for comparison were February 24 and April 27.

“We attribute these changes in data usage to the pandemic and not expected seasonal or yearly shifts in usage patterns,” said spokesman Greg Jacobs.

Saskatchewan.ca was attracting just 70 page views per minute on average in February. But page views jumped over 10,000 per minute at 2:38 p.m. on March 18, as Moe was still announcing the new measures.

That’s a 14,000 per cent increase.

For all of March, visitor sessions on the site clocked in at 3,905,061, almost four times the 944,904 recorded for February.

Bureaucracy has increasingly migrated to cyberspace, with 62 per cent of civil servants now working from home. Government Skype calls, both audio and video, have tripled from 12,000 sessions per day to 35,000.Telephone conference calls increased by a factor of 14 from the first week of February to the second full week of April, with 25 times more weekly call participants. 

The Ministry of Central Services reported a 17 per cent jump in emails received by government over the past two months, excluding the Ministry of Health.

But as civil servants spend more time on their computers, the government’s fleet is spending a lot less time on the road. The ministry has purchased 40 per cent fewer litres of fuel for its vehicles over the past four weeks, compared to the same time last year.

Alcohol wholesale volumes up 22 per cent, then fall back to normal
Retailers bought more alcohol from the Saskatchewan Liquor and Gaming Authority (SLGA) last month, just as the government began tightening pandemic restrictions.

Wholesale sales volumes were up 22 per cent over March 15 to 28, compared to the same period in 2019. SLGA spokesman David Morris said the additional demand “was likely the result of retailers stocking-up as restrictions related to COVID-19 took effect.”

But the jump didn’t last. Wholesale volumes were back to normal for the first two weeks of April. SLGA did notice a very slight uptick last week, however, with volumes out of its distribution centre up three per cent. The numbers do not include Brewer’s Distributors Ltd.

It’s unclear how much more alcohol consumers actually purchased, since province-wide retail numbers were not available.

There was no discernible trend in March for anti-anxiety medication, however. The number of prescriptions filled for benzodiazepines like Valium, Xanax and Ativan see-sawed over March, according to data provided by the College of Physicians and Surgeons, but its associate registrar does not believe the trends are statistically relevant.

One-fifth of tenants miss April rent
About 20 per cent of residential rent went totally unpaid in the first six days of April, according to the Saskatchewan Landlord Association (SLA).

The precise number is 19.7 per cent, but there’s some uncertainty due to the survey method, which is based on responses from 300 residential landlords with 14,000 units. An additional 12 per cent of tenants paid a portion of their rent, but not the full amount. The figures do not include social housing.

Cameron Choquette, the association’s executive officer, partly blames the province’s decision to suspend most landlord tenant board hearings for evictions, saying it “allows more people to take advantage of landlords by not paying their rent and not facing any consequences.”

The government has defended the suspension by saying it’s needed to ensure everyone has a safe place to self-isolate if needed during the pandemic.

March’s jobs numbers were bad, with almost 21,000 fewer Saskatchewan people employed compared to February.

April’s labour force survey is expected on Friday. But new April numbers released Wednesday show that two-thirds of the province’s businesses managed to avoid laying off staff almost entirely.

According to Statistics Canada, 66.2 per cent of businesses reported laying off between zero and one per cent of their employees due to COVID-19. That was better than any other province. Just 7.6 per cent laid off all of their employees, again the best number outside the territories. The survey period was April 3 to 24.

Some businesses are even hiring. Walmart, for instance, has hired 300 people in Saskatchewan since mid-March.

Trade and Export Development Minister Jeremy Harrison chalked the data up to a relatively more optimistic business outlook in Saskatchewan, combined with “very targeted” restrictions and a support program for small and medium businesses.

That support program, which provides $5,000 grants to qualifying businesses affected by government restrictions, has only been around for three weeks. But it’s already been bombarded with 6,317 applications.

The total value of those applications would be $24,178,000, according to Harrison. Of them, 3,586 have been approved with a value of $11,755,000.

Businesses are coming to Harrison’s ministry with thousands of questions. Since it opened in March, the Business Response Team has received 4,125 calls and 1,758 emails.

The kinds of questions have changed over the course of the pandemic. Many are now asking when they can open their doors, according to Harrison, as they wonder about “grey areas” in the Re-Open Saskatchewan plan.

Ontario Electricity Rate Changes lower OEB Regulated Price Plan costs, adjust Time-of-Use winter hours and tiered thresholds, and modify the Ontario Electricity Rebate, affecting off-peak, mid-peak, and on-peak pricing for households and small businesses.

Key Points

OEB updates lowering RPP prices, shifting TOU hours, adjusting tiers, and modifying the Ontario Electricity Rebate.

✅ Winter TOU: Off-peak 7 p.m.-7 a.m.; weekends, holidays all day.

✅ Tiered pricing adds 400 kWh at lower rate for residential users.

✅ Ontario Electricity Rebate falls to 11.7% from 17% on Nov 1.

Electricity rates are about to change for consumers across Ontario.

On November 1, households and small businesses will see their electricity rates go down under the Ontario Energy Board's (OEB) Regulated Price Plan framework.

Customer's on the OEB's tiered pricing plan will also see their bills lowered on November 1, a shift from the 2021 increase when fixed pricing ended, as winter time-of-use hours and the seasonal change in the killowatt-hour threshold take effect.

Off-peak time-of-use hours will run from 7 p.m. to 7 a.m. during weekdays, including the ultra-low overnight rates option for some customers, and all day on weekends and holidays. On-peak hours will be from 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. on weekdays, and mid-peak hours from 11 a.m. to 5 p.m. on weekdays.

The winter-tier threshold provides residential customers with an extra 400 kilowatt-hours per month at a lower price during the colder weather, alongside the off-peak price freeze in effect.

The Ontario Electricity Rebate - a pre-tax credit that shows up at the bottom of electricity bills - will also see changes as a hydro rate change takes effect on November 1. Starting next month, the rebate will drop from 17 per cent to 11.7 per cent.

For a typical residential customer, the credit will decrease electricity bills by about $13.91 per month, according to the OEB.

Under the board's winter disconnection ban, electricity providers can't turn off a residential customer's power between November 15, 2022 and April 30, 2023 for failing to pay, and earlier pandemic relief included a fixed COVID-19 hydro rate for customers.

Illinois Zero Emission Credits support nuclear plants via tradable credits tied to wholesale electricity prices, carbon costs, created by the Future Energy Jobs Bill to avert Exelon closures and sustain low-carbon power.

Key Points

State credits that value nuclear power's zero-carbon output, priced by market and carbon metrics to keep plants running.

✅ Pegged to wholesale prices, carbon costs, and state averages.

✅ Created by Future Energy Jobs Bill to prevent plant retirements.

✅ Supports Exelon Quad Cities and Clinton nuclear facilities.

Nuclear plants have produced over half of Illinois electricity generation since 2010, but the states two largest plants would have been retired amid the debate over saving nuclear plants if the state had not created a zero emission credit (ZEC) mechanism to support the facilities.

The two plants, Quad Cities and Clinton, collectively delivered more than 12 percent of the states electricity generation over the past several years. In May 2016, however, Exelon, the owner of the plants, announced that they had together lost over $800 million dollars over the previous six years and revealed plans to retire them in 2017 and 2018, similar to the Three Mile Island closure later announced for 2019 by its owner.

In December 2016, Illinois passed the Future Energy Jobs Bill, which established a zero emission credit (ZEC) mechanism

to support the plants financially. Exelon then cancelled its plans to retire the two facilities.

The ZEC is a tradable credit that represents the environmental attributes of one megawatt-hour of energy produced from the states nuclear plants. Its price is based on a number of factors that include wholesale electricity market prices, nuclear generation costs, state average market prices, and estimated costs of the long-term effects of carbon dioxide emissions.

The bill is set to take effect in June, but faces multiple court challenges as some utilities have expressed concerns that the ZEC violates the commerce clause and affects federal authority to regulate wholesale energy prices, amid gas-fired competition in nearby markets that shapes the revenue outlook.

Illinois ranks first in the United States for both generating capacity and net electricity generation from nuclear power, a resource many see as essential for net-zero emissions goals, and accounts for approximately one-eighth of the nuclear power generation in the nation.

Wall Street Fossil Fuel Pivot signals banks reassessing ESG, net-zero, and decarbonization goals, reviving oil, gas, and coal financing while recalibrating clean energy exposure amid policy shifts, regulatory rollbacks, and investment risk realignment.

Key Points

A shift as major U.S. banks ease ESG limits to fund oil, gas, coal while rebalancing alongside renewables.

✅ Banks revisit lending to oil, gas, and coal after policy shifts.

✅ ESG and net-zero commitments face reassessment amid returns.

✅ Renewables compete for capital as risk models are updated.

The global energy finance sector, worth a staggering $1.4 trillion, is undergoing a significant transformation, largely due to former President Donald Trump's renewed support for the oil, gas, and coal industries. Wall Street, which had previously aligned itself with global climate initiatives and the energy transition and net-zero goals, is now reassessing its strategy and pivoting toward a more fossil-fuel-friendly stance.

This shift represents a major change from the earlier stance, where many of the largest U.S. banks and financial institutions took a firm stance on decarbonization push, including limiting their exposure to fossil-fuel projects. Just a few years ago, these institutions were vocal supporters of the global push for a sustainable future, with many committing to support clean energy solutions and abandon investments in high-carbon energy sources.

However, with the change in administration and the resurgence of support for traditional energy sectors under Trump’s policies, these same banks are now rethinking their strategies. Financial institutions are increasingly discussing the possibility of lifting long-standing restrictions that limited their investments in controversial fossil-fuel projects, including coal mining, where emissions drop as coal declines, and offshore drilling. The change reflects a broader realignment within the energy finance sector, with Wall Street reexamining its role in shaping the future of energy.

One of the most significant developments is the Biden administration’s policy reversal, which emphasized reducing the U.S. carbon footprint in favor of carbon-free electricity strategies. Under Trump, however, there has been a renewed focus on supporting the traditional energy sectors. His administration has pushed to reduce regulatory burdens on fossil-fuel companies, particularly oil and gas, while simultaneously reintroducing favorable tax incentives for the coal and gas industries. This is a stark contrast to the Biden administration's efforts to incentivize the transition toward renewable energy and zero-emissions goals.

Trump's policies have, in effect, sent a strong signal to financial markets that the fossil-fuel industry could see a resurgence. U.S. banks, which had previously distanced themselves from financing oil and gas ventures due to the pressure from environmental activists and ESG (Environmental, Social, and Governance) investors, as seen in investor pressure on Duke Energy, are now reconsidering their positions. Major players like JPMorgan Chase and Goldman Sachs are reportedly having internal discussions about revisiting financing for energy projects that involve high carbon emissions, including controversial oil extraction and gas drilling initiatives.

The implications of this shift are far-reaching. In the past, a growing number of institutional investors had embraced ESG principles, with the goal of supporting the transition to renewable energy sources. However, Trump’s pro-fossil fuel stance appears to be emboldening Wall Street’s biggest players to rethink their commitment to green investing. Some are now advocating for a “balanced approach” that would allow for continued investment in traditional energy sectors, while also acknowledging the growing importance of renewable energy investments, a trend echoed by European oil majors going electric in recent years.

This reversal has led to confusion among investors and analysts, who are now grappling with how to navigate a rapidly changing landscape. Wall Street's newfound support for the fossil-fuel industry comes amid a backdrop of global concerns about climate change. Many investors, who had previously embraced policies aimed at curbing the effects of global warming, are now finding it harder to reconcile their environmental commitments with the shift toward fossil-fuel-heavy portfolios. The reemergence of fossil-fuel-friendly policies is forcing institutional investors to rethink their long-term strategies.

The consequences of this policy shift are also being felt by renewable energy companies, which now face increased competition for investment dollars from traditional energy sectors. The shift towards oil and gas projects has made it more challenging for renewable energy companies to attract the same level of financial backing, even as demand for clean energy continues to rise and as doubling electricity investment becomes a key policy call. This could result in a deceleration of renewable energy projects, potentially delaying the progress needed to meet the world’s climate targets.

Despite this, some analysts remain optimistic that the long-term shift toward green energy is inevitable, even if fossil-fuel investments gain a temporary boost. As the world continues to grapple with the effects of climate change, and as technological advancements in clean energy continue to reduce costs, the transition to renewables is likely to persist, regardless of the political climate.

The shift in Wall Street’s approach to energy investments, spurred by Trump’s pro-fossil fuel policies, is reshaping the $1.4 trillion global energy finance market. While the pivot towards fossil fuels may offer short-term gains, the long-term trajectory for energy markets remains firmly in the direction of renewables. The next few years will be crucial in determining whether financial institutions can balance the demand for short-term profitability with their long-term environmental responsibilities.
