Old electricity meters being replaced with new “smart meters” are partly to blame for the rising cost of power in some Ontario homes, says Energy Minister Brad Duguid.

Under fire again for rising hydro rates, Duguid said that the old-style meters were “40 to 50 years old” in some cases and not as accurate as the new ones.

“We’ve heard a lot of political rhetoric about bills doubling and things like that. I’m not suggesting that bills haven’t gone up but there are a variety of reasons,” he told reporters.

One is the long and unusually hot summer that prompted many people to keep air conditioners humming much more than in the previous two summers and another is what Duguid called “old, crumbling” meters.

“When you put in the new meter you find out the previous meter wasn’t billing and working properly. So the new meter is bringing bills up to date and is more accurate.”

Almost one million of the 4.5 million households in Ontario now have smart meters, being installed as the system is modernized and as the government makes new investments in electricity generation to replace old coal-fired plants — another factor Duguid blames for rising bills.

New Democrat Leader Andrea Horwath said this is the first time sheÂ’s heard the old meter explanation for the jump in electricity costs.

“Every day it’s a new story from the minister,” she said, repeating her call for the government to take the 8 per cent provincial portion of the new harmonized sales tax HST off hydro bills.

“The HST is salt in the wound to hydro costs. Just take the HST off hydro and start giving people a break.”

Smart meters allow consumers to be subject to “time of use” electricity prices, which are higher at peak periods from 7 to 11 a.m. and 5 to 9 p.m., encouraging them to shift power use to lower-cost times like late nights.

But critics of the government are saying those time periods make it difficult for many people to avoid high-priced electricity, forcing their bills up.

Winter Storm Leaves Many In Texas Without Power And Water

Texas Power Grid Crisis strains ERCOT as extreme cold, ice storms, and heavy snow trigger rolling blackouts, load shedding, and boil-water notices, leaving millions without electricity while frozen turbines and low gas pressure hinder generation.

 

Key Points

A statewide emergency of outages and boil-water notices as ERCOT battles extreme cold and load shedding.

✅ Millions without power; ERCOT orders load shedding

✅ Boil-water notices in Austin, Houston, Fort Worth

✅ Frozen equipment, low gas pressure, extreme cold disrupt supply

 

Nearly 3 million homes and businesses in Texas remain without power, some for a third consecutive day, as severe winter weather continues to pummel the state, forcing some localities to issue boil-water notices and urge residents to reduce their electricity usage.

Heavy snowfall, ice storms and bitter temperatures continue to put an enormous strain on the state's power grid. This as the Electric Reliability Council of Texas (ERCOT), which manages roughly 75% of the Texas power grid, announced Wednesday morning that some 600,000 households had power restored overnight.

That still left another 2.7 million customers having to endure extreme cold with no indication of when the thaw would break in their homes.

"We know millions of people are suffering," ERCOT's president and CEO, Bill Magness, said in a statement Wednesday. "We have no other priority than getting them electricity. No other priority."

ERCOT also said Wednesday that it was urging local utilities to shed some 14,000 megawatts of load, which translates to roughly 2.8 million customers, to prepare for a sudden increase in demand.

"The ability to restore more power is contingent on more generation coming back online," said Dan Woodfin, the senior director of ERCOT's system operations, and utility supply-chain constraints can further complicate repair timelines for some utilities.

He said that about 185 generating units were offline, stemming from a range of factors including frozen wind turbines, low gas pressure and frozen instrumentation.

But many Texans feel abandoned by the council and power companies and they are lashing out at the local face of utilities.

The City of Austin's community-owned electric utility, Austin Energy, issued a tweet saying crews that are working to restore power are facing harassment.


"Our crews have been working 24/7 and in these elements," Austin Energy announced. "Some of our crews are reporting incidents of harassment, threatening them and even throwing things at them."

Officials pleaded with the public to remain calm. "I know people are extremely frustrated. But please, I bet of you, do not approach AE crews."

Parts of Austin are under a boil water notice, which Austin Water Director Greg Meszaros attempted to explain during a press briefing Wednesday afternoon.

"There was a large main break in that area, maybe multiple ones. We're seeing main breaks and pipes bursting by the tens of thousands. Our entire system is under stress," Meszaros said.

It's not just the Lone Star State that is being crippled by the arctic blast, with a deep freeze slamming the energy sector across the country.

At least two dozen people have died this week from weather-related incidents, according to The Associated Press.

The National Weather Service reports that more than 100 million Americans are being affected by extreme winter weather from the south central U.S. to the East Coast, including Arkansas, Louisiana, Mississippi, North Carolina, Virginia and West Virginia, and analysts warn of blackout risks nationwide during extreme heat as well.

The National Weather Service adds that cold temperatures over the nation's heartland will begin to "moderate in the coming days" but that many parts will remain 20 to 35 degrees below normal in the Great Plains, Mississippi Valley and lower Great Lakes region.

"Potential is increasing for significant icing across portions of the Mid-Atlantic, which will be very impactful, especially for those hardest hit from the previous ice storm," the National Weather Service tweeted Wednesday.

Texas Gov. Greg Abbott railed against ERCOT, and Elon Musk criticized the agency as unreliable, saying the utility "has been anything but reliable over the past 48 hours."

"This is unacceptable," Abbott added, as residents were facing rotating intentional power outages. The governor issued an executive order that will add reforms for how the power grid is managed, including grid reliability improvements under discussion, as an emergency legislative item for the state legislature to review.

The rolling power outages forced Fort Worth to extend a boil-water notice for roughly 212,000 residents. Officials said the outages affected the city's systems that both treat water and move it to customers.

Fort Worth officials said nine other localities that purchase water from the city are also affected, including Haslet, Keller, Lake Worth and Northlake.

Officials in Houston also issued a boil-water notice for the city's residents Wednesday.

"Do not drink the water without boiling it first," Houston Public Works said from its official Twitter account. "Bring all water to a boil for at least two minutes. Let it cool before using."

In Harris County, which includes Houston, Judge Lina Hidalgo warned residents about extended power outages.

"Let me give it to you straight, based on the visibility I have: Whether you have power or not right now, there is a possibility of power outages even beyond the length of this weather," Hidalgo said, according to Houston Public Media.

The NPR member station adds that county officials have also reported more than 300 cases of carbon monoxide poisoning since Monday as residents going without electricity search desperately for alternative sources of warmth.

"In no uncertain terms, this is a public health disaster and a public health emergency," Samuel Prater, an emergency physician at Memorial Hermann-Texas Medical Center, said at a news briefing Tuesday.

Prater warned residents that over the last 24 hours, emergency officials "have seen a striking increase in the number of cases related to improper heating sources," including indoor use of generators, charcoal grills, campfire stoves and other devices that are being used to warm homes. The result, he added, is carbon monoxide poisoning of entire families.

"If you think you or a loved one has become ill from carbon monoxide poisoning, first thing you need to do is get outside to fresh air," Prater said.

A woman and an 8-year-old girl are among those who have reportedly died from carbon monoxide poisoning after a vehicle was left running inside a garage in an attempt to generate heat, according to Houston's ABC affiliate.

As Texas endures further weather-related issues, including road and highway closures, there's a renewed focus on how the Texas power grid has failed, and why the grid is facing another crisis amid this prolonged cold.

The Texas electrical grid is "facing conditions that it was not designed for," said Emily Grubert, a professor at Georgia Tech whose expertise includes electric networks.

"These are really extreme conditions for the Texas grid. It's very cold. It's cold across the entire state, and it's cold for a long time. This does not happen very often," she said in an interview with NPR's Morning Edition.

"Demand really spiked both in the electricity and the natural gas systems at the same time as a lot of the generators were not able to operate because of those cold conditions, and not being prepared for it is really what's going on," Grubert said. "But a lot of grids are susceptible to really, really major failures when they are this far outside of design conditions."

Abbott told Fox News on Tuesday that with weather-related shutdowns in wind and solar energy, which account for more than 10% of the state's grid, renewable energy is partly to blame for the Texas power crisis, even as he later touted the grid's readiness heading into the fall.

"It just shows that fossil fuel is necessary for the state of Texas as well as other states to make sure that we'll be able to heat our homes in the wintertime and cool our homes in the summertime," Abbott said.

But Grubert said that "coal, gas and nuclear actually shut down because of the extreme cold due to things like instruments freezing, et cetera. So I think the overall point here is all of the fuels were really, really struggling."

UK net zero policies: What do changes mean?

UK Net Zero Policy Delay shifts EV sales ban to 2035, eases boiler phase-outs, keeps ZEV mandate, backs North Sea oil and gas, accelerates onshore wind and grid upgrades while targeting 2050 emissions goals.

 

Key Points

Delay moves EV and heating targets to 2035, tweaks mandates, and shifts energy policy, keeping the 2050 net zero goal.

✅ EV sales ban shifts to 2035; ZEV mandate trajectory unchanged

✅ Heat pump grants rise to £7,500; boiler phase-out eased

✅ North Sea oil, onshore wind, grid and nuclear plans advance

 

British Prime Minister Rishi Sunak has said he would delay targets for changing cars and domestic heating to maintain the consent of the British people in the switch to net zero as part of the global energy transition under way.

Sunak said Britain was still committed to achieving net zero emissions by 2050, similar to Canada's race to net zero goals, and denied watering down its climate targets.

Here are some of the current emissions targets for Britain's top polluting sectors and how the announcement impacts them.


TRANSPORTATION
Transport accounts for more than a third (34%) of Britain's total carbon dioxide (CO2) emissions, the most of any sector.

Sunak announced a delay to introducing a ban on new petrol and diesel cars and vans. It will now come into force in 2035 rather than in 2030.

There were more than 1.1 million electric cars in use on UK roads as of April - up by more than half from the previous year to account for roughly one in every 32 cars, according to the country's auto industry trade body.

The current 2030 target was introduced in November 2020 as a central part of then-Prime Minister Boris Johnson's plans for a "green revolution". As recently as Monday, transport minister Mark Harper restated government support for the policy.

Britain’s independent climate advisers, the Climate Change Committee, estimated a 2030 phase out of petrol, diesel and hybrid vehicles could save up to 110 million tons of carbon dioxide equivalent emissions compared with a 2035 phase out.

ohnson's policy already allowed for the continued sale of hybrid cars and vans that can drive long stretches without emitting carbon until 2035.

The transition is governed by a zero-emission vehicle (ZEV) mandate, a shift echoed by New Zealand's electricity transition debates, which means manufacturers must ensure an increasing proportion of the vehicles they sell in the UK are electric.

The current proposal is for 22% of a car manufacturer's sales to be electric in 2024, rising incrementally each year to 100% in 2035.

The government said on Wednesday that all sales of new cars from 2035 would still be zero emission.

Sunak said that proposals that would govern how many passengers people should have in a car, or proposals for new taxes to discourage flying, would be scrapped.


RESIDENTIAL
Residential emissions, the bulk of which come from heating, make up around 17% of the country's CO2 emissions.

The government has a target to reduce Britain's energy consumption from buildings and industry by 15% by 2030, and had set a target to phase out installing new and replacement gas boilers from 2035, as the UK moves towards heat pumps, amid an IEA report on Canada's power needs noting more electricity will be required.

Sunak said people would have more time to transition, and the government said that off-gas-grid homes could continue to install oil and liquefied petroleum gas boilers until 2035, rather than being phased out from 2026.

However, his announcements that the government would not force anyone to rip out an existing boiler and that people would only have to make the switch when replacing one from 2035 restated existing policy.

He also said there would be an exemption so some households would never have to switch, but the government would increase an upgrade scheme that gives people cash to replace their boilers by 50% to 7,500 pounds ($9,296.25).

Currently almost 80% of British homes are heated by gas boilers. In 2022, 72,000 heat pumps were installed. The government had set a target of 600,000 heat pump installations per year by 2028.

A study for Scottish Power and WWF UK in June found that 6 million homes would need to be better insulated by 2030 to meet the government's target to reduce household energy consumption, but current policies are only expected to deliver 1.1 million.

The study, conducted by Frontier Economics, added that 1.5 million new homes would still need heat pumps installed by 2030.

Sunak said that the government would subsidise people who wanted to make their homes energy efficient but never force a household to do it.

The government also said it was scrapping policies that would force landlords to upgrade the energy efficiency of their properties.


ENERGY
The energy sector itself is a big emitter of greenhouse gases, contributing around a quarter of Britain's emissions, though the UK carbon tax on coal has driven substantial cuts in coal-fired electricity in recent years.

In July, Britain committed to granting hundreds of licences for North Sea oil and gas extraction as part of efforts to become more energy independent.

Sunak said he would not ban new oil and gas in the North Sea, and that future carbon budgets for governments would have to be considered alongside the plans to meet them.

He said the government would shortly bring forward new plans for energy infrastructure to improve Britain's grid, including the UK energy plan, while speeding up planning.

Offshore wind power developers warned earlier this month that Britain's climate goals could be at risk, even as efforts like cleaning up Canada's electricity highlight the importance of power-sector decarbonization, after a subsidy auction for new renewable energy projects did not attract any investment in those planned off British coasts.

Britain is aiming to develop 50 gigawatts (GW) of offshore wind capacity by 2030, up from around 14 GW now.

Sunak highlighted that Britain is lifting a ban on onshore wind, investing in carbon capture and building new nuclear power stations.

Military Is Ramping Up Preparation For Major U.S. Power Grid Hack

DARPA RADICS Power Grid Security targets DoD resilience to cyber attacks, delivering early warning, detection, isolation, and characterization tools, plus a secure emergency network to protect critical infrastructure and speed grid restoration and communications.

 

Key Points

A DoD/DARPA initiative to detect, contain, and rapidly recover the U.S. grid from sophisticated cyber attacks.

✅ Early warning separates attacks from routine outages

✅ Pinpoints intrusion points and malware used

✅ Builds secure emergency network for rapid restoration

 

The U.S. Department of Defense is growing increasingly concerned about hackers taking down our power grid and crippling the nation, reflecting a renewed focus on grid protection across agencies, which is why the Pentagon has created a $77-million security plan that it hopes will be up and running by 2020.

The U.S. power grid is threatened every few days. While these physical and cyber attacks have never led to wide-scale outages, attacks are getting more sophisticated. According to a 494-page report released by the Department of Energy in January and a new grid report card, the nation’s grid “faces imminent danger from cyber attacks.” Such a major, sweeping attack could threaten “U.S. lifeline networks, critical defense infrastructure, and much of the economy; it could also endanger the health and safety of millions of citizens.” If it were to happen today, America could be powered-down and vulnerable for weeks.

#google#

The DoD is working on an automated system to speed up recovery time to a week or less — what it calls the Rapid Attack Detection, Isolation, and Characterization (RADICS) program. DARPA, the Pentagon’s research arm, originally solicited proposals in late 2015, asking for technology that did three things. Primarily, it had to detect early warning signs and distinguish between attacks and normal outages, especially after intrusions at U.S. electric utilities underscored the risk, but it also had to pinpoint the access point of the attack and determine what malicious software was used. Finally, it must include an emergency system that can rapidly connect various power-supply centers, without any human coordination. This would allow emergency and military responders to have an ad hoc communication system in place moments after an attack.

“If a well-coordinated cyberattack on the nation’s power grid were to occur today, the time it would take to restore power would pose daunting national security challenges,” said DARPA program manager John Everett, in a statement, at the time. “Beyond the severe domestic impacts, including economic and human costs, prolonged disruption of the grid would hamper military mobilization and logistics, impairing the government’s ability to project force or pursue solutions to international crises.”

DARPA plans to spend $77 million on RADICS, while DOE funding to improve the grid complements these initiatives. Last November, SRI International announced it had received $7.3 million from the program. In December, Raython was granted $9 million. The latest addition is BAE Systems, which received $8.6 million last month to develop technology that detects and contains power-grid threats, and creates a secure emergency provisional system that restores some power and communication in the wake of an attack — what is being called a secure emergency network.

According to the military news site Defense Systems, BAE’s SEN would rely on radio, satellite, or wireless internet — particularly as ransomware attacks continue to rise — whatever is available that allows the grid to continue working. The SEN would serve as a wireless connection between separate power grid stations.

While the ultimate goal of the RADICS program will be the restoration of civilian power and communications, the SEN will prioritize communication networks that would be used for defense or combat, so the U.S. government can still wage war while the rest of us are in the dark.

TCA Electric Leads Hydrogen Crane Project at Vancouver Port

Hydrogen Fuel Cell Crane Port of Vancouver showcases zero-emission RTG technology by DP World, TCA Electric, and partners, using hydrogen-electric fuel cells, battery energy storage, and regenerative capture to decarbonize container handling operations.

 

Key Points

A retrofitted RTG crane powered by hydrogen fuel cells, batteries, and regeneration to cut diesel use and CO2 emissions.

✅ Dual fuel cell system charges high-voltage battery

✅ Regenerative capture reduces energy demand and cost

✅ Pilot targets zero-emission RTG fleets by 2040

 

In a groundbreaking move toward sustainable logistics, TCA Electric, a Chilliwack-based industrial electrical contractor, is at the forefront of a pioneering hydrogen fuel cell crane project at the Port of Vancouver. This initiative, led by DP World in collaboration with TCA Electric and other partners, marks a significant step in decarbonizing port operations and showcases the potential of hydrogen technology in heavy-duty industrial applications.

A Vision for Zero-Emission Ports

The Port of Vancouver, Canada's largest port, has long been a hub for international trade. However, its operations have also contributed to substantial greenhouse gas emissions, even as DP World advances an all-electric berth in the U.K., primarily from diesel-powered Rubber-Tired Gantry (RTG) cranes. These cranes are essential for container handling but are significant sources of CO₂ emissions. At DP World’s Vancouver terminal, 19 RTG cranes account for 50% of diesel consumption and generate over 4,200 tonnes of CO₂ annually. 

To address this, the Vancouver Fraser Port Authority and the Province of British Columbia have committed to transforming the port into a zero-emission facility by 2050, supported by provincial hydrogen investments that accelerate clean energy infrastructure across B.C. This ambitious goal has spurred several innovative projects, including the hydrogen fuel cell crane pilot. 

TCA Electric’s Role in the Hydrogen Revolution

TCA Electric's involvement in this project underscores its expertise in industrial electrification and commitment to sustainable energy solutions. The company has been instrumental in designing and implementing the electrical systems that power the hydrogen fuel cell crane. This includes integrating the Hydrogen-Electric Generator (HEG), battery energy storage system, and regenerative energy capture technologies. The crane operates using compressed gaseous hydrogen stored in 15 pressurized tanks, which feed a dual fuel cell system developed by TYCROP Manufacturing and H2 Portable. This system charges a high-voltage battery that powers the crane's electric drive, significantly reducing its carbon footprint. 

The collaboration between TCA Electric, TYCROP, H2 Portable, and HTEC represents a convergence of local expertise and innovation. These companies, all based in British Columbia, have leveraged their collective knowledge to develop a world-first solution in the industrial sector, while regional pioneers like Harbour Air's electric aircraft illustrate parallel progress in aviation. TCA Electric's leadership in this project highlights its role as a key enabler of the province's clean energy transition. 

Demonstrating Real-World Impact

The pilot project began in October 2023 with the retrofitting of a diesel-powered RTG crane. The first phase included integrating the hydrogen-electric system, followed by a one-year field trial to assess performance metrics such as hydrogen consumption, energy generation, and regenerative energy capture rates. Early results have been promising, with the crane operating efficiently and emitting only steam, compared to the 400 kilograms of CO₂ produced by a comparable diesel unit. 

If successful, this project could serve as a model for decarbonizing port operations worldwide, mirroring investments in electric trucks at California ports that target landside emissions. DP World plans to consider converting its fleet of RTG cranes in Vancouver and Prince Rupert to hydrogen power, aligning with its global commitment to achieve carbon neutrality by 2040.

Broader Implications for the Industry

The success of the hydrogen fuel cell crane pilot at the Port of Vancouver has broader implications for the shipping and logistics industry. It demonstrates the feasibility of transitioning from diesel to hydrogen-powered equipment in challenging environments, and aligns with advances in electric ships on the B.C. coast. The project's success could accelerate the adoption of hydrogen technology in other ports and industries, contributing to global efforts to reduce carbon emissions and combat climate change.

Moreover, the collaboration between public and private sectors in this initiative sets a precedent for future partnerships aimed at advancing clean energy solutions. The support from the Province of British Columbia, coupled with the expertise of companies like TCA Electric and utility initiatives such as BC Hydro's vehicle-to-grid pilot underscore the importance of coordinated efforts in achieving sustainability goals.

Looking Ahead

As the field trial progresses, stakeholders are closely monitoring the performance of the hydrogen fuel cell crane. The data collected will inform decisions on scaling the technology and integrating it into broader port operations. The success of this project could pave the way for similar initiatives in other regions, complementing the province's move to electric ferries with CIB support, promoting the widespread adoption of hydrogen as a clean energy source in industrial applications.

TCA Electric's leadership in this project exemplifies the critical role of skilled industrial electricians in driving the transition to sustainable energy solutions. Their expertise ensures the safe and efficient implementation of complex systems, making them indispensable partners in the journey toward a zero-emission future.

The hydrogen fuel cell crane pilot at the Port of Vancouver represents a significant milestone in the decarbonization of port operations. Through innovative partnerships and local expertise, this project is setting the stage for a cleaner, more sustainable future in global trade and logistics.

SaskPower to buy more electricity from Manitoba Hydro

SaskPower-Manitoba Hydro Power Sale outlines up to 215 MW of clean hydroelectric baseload for Saskatchewan, supporting renewable energy targets, lower greenhouse gas emissions, and interprovincial transmission line capacity starting 2022 under a 30-year agreement.

 

Key Points

A long-term deal supplying up to 215 MW of hydroelectric baseload from Manitoba to Saskatchewan to cut emissions.

✅ Up to 215 MW delivered starting 2022 via new intertie

✅ Supports 40% GHG reduction target by 2030

✅ 30-year term; complements wind and solar integration

 

Saskatchewan's Crown-owned electric utility has made an agreement to buy more hydroelectricty from Manitoba.

A term sheet providing for a new long--term power sale has been signed between Manitoba Hydro and SaskPower which will see up to 215 megawatts flow from Manitoba to Saskatchewan, as new turbine investments advance in Manitoba, beginning in 2022.

SaskPower has two existing power purchase agreements with Manitoba Hydro that were made in 2015 and 2016, but the newest one announced Monday is the largest, as financial pressures at Manitoba Hydro continue.

SaskPower President and CEO Mike Marsh says in a news release that the clean, hydroelectric power represents a significant step forward when it comes to reaching the utility's goal of reducing greenhouse gas emissions by 40 per cent by 2030, aligning with progress on renewable electricity by 2030 initiatives.

Marsh says it's also reliable baseload electricity, which SaskPower will need as it adds more intermittent generation options like wind and solar.

SaskPower says a final legal contract for the sale is expected to be concluded by mid-2019 and be in effect by 2022, and the purchase agreement would last up to 30 years.

"Manitoba Hydro has been a valued neighbour and business partner over the years and this is a demonstration of that relationship," Marsh said in the news release.

The financial terms of the agreement are not being released, though SaskPower's latest annual report offers context on its finances.

Both parties say the sale will partially rely on the capacity provided by a new transmission line planned for construction between Tantallon, Sask. and Birtle, Man. that was previously announced in 2015 and is expected to be in service by 2021.

"Revenues from this sale will assist in keeping electricity rates affordable for our Manitoba customers, while helping SaskPower expand and diversify its renewable energy supply," Manitoba Hydro president and CEO Kelvin Shepherd said in the utility's own news release.

In 2015, SaskPower signed a 25 megawatt agreement with Manitoba Hydro that lasts until 2022. A 20-year agreement for 100 megawatts was signed in 2016 and comes into effect in 2020, and SaskPower is also exploring a purchase from Flying Dust First Nation to further diversify supply.

The deals are part of a memorandum of understanding signed in 2013 involving up to 500 megawatts.

Sustaining U.S. Nuclear Power And Decarbonization

Existing Nuclear Reactor Lifetime Extension sustains carbon-free electricity, supports deep decarbonization, and advances net zero climate goals by preserving the US nuclear fleet, stabilizing the grid, and complementing advanced reactors.

 

Key Points

Extending licenses keeps carbon-free nuclear online, stabilizes grid, and accelerates decarbonization toward net zero.

✅ Preserves 24/7 carbon-free baseload to meet climate targets

✅ Avoids emissions and replacement costs from premature retirements

✅ Complements advanced reactors; reduces capital and material needs

 

Nuclear power is the single largest source of carbon-free energy in the United States and currently provides nearly 20 percent of the nation’s electrical demand. As a result, many analyses have investigated the potential of future nuclear energy contributions in addressing climate change and investing in carbon-free electricity across the sector. However, few assess the value of existing nuclear power reactors.

Research led by Pacific Northwest National Laboratory (PNNL) Earth scientist Son H. Kim, with the Joint Global Change Research Institute (JGCRI), a partnership between PNNL and the University of Maryland, has added insight to the scarce literature and is the first to evaluate nuclear energy for meeting deep decarbonization goals amid rising credit risks for nuclear power identified by Moody's. Kim sought to answer the question: How much do our existing nuclear reactors contribute to the mission of meeting the country’s climate goals, both now and if their operating licenses were extended?

As the world races to discover solutions for reaching net zero as part of the global energy transition now underway, Kim’s report quantifies the economic value of bringing the existing nuclear fleet into the year 2100. It outlines its significant contributions to limiting global warming.

Plants slated to close by 2050 could be among the most important players in a challenge requiring all available carbon-free technology solutions—emerging and existing—alongside renewable electricity in many regions, the report finds. New nuclear technology also has a part to play, and its contributions could be boosted by driving down construction costs.  

“Even modest reductions in capital costs could bring big climate benefits,” said Kim. “Significant effort has been incorporated into the design of advanced reactors to reduce the use of all materials in general, such as concrete and steel because that directly translates into reduced costs and carbon emissions.”

Nuclear power reactors face an uncertain future, and some utilities face investor pressure to release climate reports as well.
The nuclear power fleet in the United States consists of 93 operating reactors across 28 states. Most of these plants were constructed and deployed between 1970-1990. Half of the fleet has outlived its original operating license lifetime of 40 years. While most reactors have had their licenses renewed for an additional 20 years, and some for another 20, the total number of reactors that will receive a lifetime extension to operate a full 80 years from deployment is uncertain.

Other countries also rely on nuclear energy. In France, for example, nuclear energy provides 70 percent of the country’s power supply. They and other countries must also consider extending the lifetime, retiring, or building new, modern reactors while navigating Canadian climate policy implications for electricity grids. However, the U.S. faces the potential retirement of many reactors in a short period—this could have a far stronger impact than the staggered closures other countries may experience.

“Our existing nuclear power plants are aging, and with their current 60-year lifetimes, nearly all of them will be gone by 2050. It’s ironic. We have a net zero goal to reach by 2050, yet our single largest source of carbon-free electricity is at risk of closure, as seen in New Zealand's electricity transition debates,“ said Kim.
