As temperatures soar across various regions, millions of households are facing the threat of U.S. blackouts due to strain on power grids and heightened demand for cooling during summer heatwaves. This article delves into the causes behind these potential shut-offs, the impact on affected communities, and strategies to mitigate such risks in the future.

Summer Heatwave Challenges

Summer heatwaves bring not only discomfort but also significant challenges to electrical grids, particularly in densely populated urban areas where air conditioning units and cooling systems, along with the data center demand boom, strain the capacity of infrastructure designed to meet peak demand. As temperatures rise, the demand for electricity peaks, pushing power grids to their limits and increasing the likelihood of disruptions.

Vulnerable Populations

The risk of electricity shut-offs disproportionately affects vulnerable populations, including low-income households, seniors, and individuals with medical conditions that require continuous access to electricity for cooling or medical devices. These groups are particularly susceptible to heat-related illnesses and discomfort when faced with more frequent outages during extreme heat events.

Utility Response and Management

Utility companies play a critical role in managing electricity demand and mitigating the risk of shut-offs during summer heatwaves. Strategies such as load shedding, where electricity is temporarily reduced in specific areas to balance supply and demand, and deploying AI for demand forecasting are often employed to prevent widespread outages. Additionally, utilities communicate with customers to provide updates on potential shut-offs and offer advice on energy conservation measures.

Community Resilience

Community resilience efforts are crucial in addressing the challenges posed by summer heatwaves and electricity shut-offs, especially as Canadian grids face harsher weather that heightens outage risks. Local governments, non-profit organizations, and community groups collaborate to establish cooling centers, distribute fans, and provide support services for vulnerable populations during heat emergencies. These initiatives help mitigate the health impacts of extreme heat and ensure that all residents have access to relief from oppressive temperatures.

Long-term Solutions

Investing in resilient infrastructure, enhancing energy efficiency, and promoting renewable energy sources are long-term solutions to reduce the risk of electricity shut-offs during summer heatwaves by addressing grid vulnerabilities that persist. By modernizing electrical grids, integrating smart technologies, and diversifying energy sources, communities can enhance their capacity to withstand extreme weather events and ensure reliable electricity supply year-round.

Public Awareness and Preparedness

Public awareness and preparedness are essential components of mitigating the impact of electricity shut-offs during summer heatwaves. Educating residents about energy conservation practices, encouraging the use of programmable thermostats, and promoting the importance of emergency preparedness plans empower individuals and families to navigate heat emergencies safely and effectively.

Conclusion

As summer heatwaves become more frequent and intense due to climate change impacts on the grid, the risk of electricity shut-offs poses significant challenges to communities across the globe. By implementing proactive measures, enhancing infrastructure resilience, and fostering community collaboration, stakeholders can mitigate the impact of extreme heat events and ensure that all residents have access to safe and reliable electricity during the hottest months of the year.

North Carolina Utility Arrears Crisis strains households and municipal budgets as COVID-19 cuts jobs; unpaid utility bills mount, shutoffs loom, and emergency aid, unemployment benefits, and CARES Act relief lag behind rising arrears across cities.

Key Points

A COVID-19 driven spike in unpaid utility bills, threatening households and municipal budgets as federal aid lapses.

✅ 1 million families behind on power, water, sewage bills

✅ $218M arrears accrued April to June, double last year

✅ Municipal utilities face shutoffs, budget shortfalls

As many as 1 million families in North Carolina have fallen behind on their electric, water and sewage bills, a sign of energy insecurity threatening residents and their cities with severe financial hardship unless federal lawmakers act to approve more emergency aid.

The trouble stems from the widespread economic havoc wrought by the coronavirus, which has left millions of workers out of a job and struggling to cover their monthly costs as some states moved to suspend utility shut-offs to provide relief. Together, they’ve been late or missed a total of $218 million in utility payments between April 1 and the end of June, according to data released recently by the state, nearly double the amount in arrears at this time last year.

In some cases, cities that own or operate their own utilities have been forced to absorb these losses, as some utilities reconnected customers to prevent harm, creating a dire situation in which the government’s attempt to save people from the financial brink instead has pushed municipal coffers to their own breaking point.

In Elizabeth City, N.C., for example, about 2,500 residents haven’t paid their electric bills on time, according to Richard Olson, the city manager. The late payments at one point proved so problematic that Olson said he calculated Elizabeth City wouldn’t have enough money to pay for its expenses in July. In response, city leaders requested and obtained a waiver from a statewide order, similar to New York’s disconnection moratorium, issued in March, that protects people from being penalized for their past-due utility bills.

The predicament has presented unique budget challenges throughout North Carolina, while illustrating the consequences of a cash crunch plaguing the entire country, where proposals such as a Texas electricity market bailout surfaced following severe grid stress. State and federal leaders have extended a range of coronavirus relief programs since March to try to help people through the pandemic. But the money is limited and restricted — and it’s not clear whether more help from Congress is on the way — creating a crisis in which the nation’s economic woes are outpacing some of the aid programs adopted to combat them.

“We are entering a phase where the utilities [may] be able to shut off power, but what was propping up people’s economic lives, the unemployment benefits and Cares Act support, won’t be there,” said Paul Meyer, the executive director of the North Carolina League of Municipalities.

White House, GOP in disarray over coronavirus spending plan as deadline nears on expiring emergency aid

The future of that safety-net support — and other federal aid — hangs in the balance as lawmakers returned to work this week in their final sprint ahead of the August recess. The White House and congressional leaders are split over the contours of the next coronavirus relief package, including the need to extend more aid to cities and states as some utilities have waived fees to help customers, and reauthorize an extra $600 in weekly unemployment payments that were approved as part of the Cares Act in March.

Outside Washington, workers, businesses and government officials nationwide have pleaded with federal lawmakers to renew or expand those programs. Last week, Roy Cooper, the Democratic governor of North Carolina, urged Congress to act swiftly and adopt a wide array of new federal spending, including proposals for DOE nuclear cleanup funding, stressing in a letter that the “actions you take in the next few weeks are vital to our ability to emerge from this crisis. ”

Alberta Electricity Demand Record surges during a deep freeze, as AESO reports peak load in megawatts and ENMAX notes increased usage in Calgary and Edmonton, with thermostats up amid a cold snap straining power grid.

Key Points

It is the highest electricity peak load recorded by AESO, reflecting maximum grid usage during cold snaps.

✅ AESO reported 11,729 MW peak during the deep freeze

✅ ENMAX saw a 13 percent demand jump week over week

✅ Cold snap drove thermostats up in Calgary and Edmonton

Albertans are cranking up their thermostats and blasting heat into their homes at overwhelmingly high rates as the deep freeze continues across the region. 

It’s so cold that the province set a new all-time record Tuesday evening for electricity usage. 

According to the Alberta Electric System Operator (AESO), as electricity prices spike in Alberta during extreme demand, 11,729 MW of power was used around 7 p.m. Tuesday, passing the previous record set in January of last year by 31 MW.

Temperatures reached a low of -29 C in Calgary, where rising electricity bills have strained budgets, on Tuesday while Edmonton saw a low of -30 C, according to Environment Canada. Wind chill  made it feel closer to -40.

“That increase — 31 Megawatts — is sizeable and about the equivalent of a moderately sized generation facility,” said AESO communications director, Mike Deising. 

“We do see higher demand in winter because it’s cold and it’s dark and that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces,” and with the UCP scrapping the price cap earlier that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces.”

Deising adds Alberta’s electricity usage over the last year has actually been much lower than average, though experts urge Albertans to lock in rates amid expected volatility, despite more people staying home during the pandemic. 

That trend was continuing into 2021, but as Alberta's rising electricity prices draw attention, it’s expected that more records could be broken. 

“If the cold snap continues we may likely set another record (Wednesday) or (Thursday), depending on what happens with the temperatures,” he said. 

Meanwhile, ENMAX has reported an average real-time system demand of 1,400 MW for the city of Calgary. 

That amount is still a far cry from the current season record of 1,619 MW (Aug. 18, 2020), the all-time winter record of 1,653MW (Dec. 2, 2013), and the all-time summer record of 1,692 MW (Aug. 10, 2018). 

ENMAX says electricity demand has increased quite significantly over the past week — by about 13 per cent — since the cold snap set in. 

As a result, the energy company is once again rolling out its ‘Winter Wise’ campaign in an effort to encourage Calgarians to manage both electricity and natural gas use in the winter, even as a consumer price cap on power bills is enabled by new legislation.

U.S. EV and Hybrid Sales 2024 show slower adoption versus gas-powered cars, as charging infrastructure gaps, range anxiety, higher upfront costs, and affordability concerns persist despite incentives, battery tech advances, and expanding fast-charging networks.

Key Points

They represent 10-15% of U.S. car sales, lagging gas models due to costs, charging gaps, range anxiety, and access.

✅ 10-15% of U.S. auto sales; gas cars dominate

✅ Barriers: upfront cost, limited charging, range anxiety

✅ Incentives, battery tech, and networks may boost adoption

Sales of hybrid and electric vehicles (EVs) in the U.S. are continuing to trail behind traditional gas-powered vehicles in 2024, despite significant advancements in automotive technology and growing public awareness of environmental concerns. While the electric vehicle market has seen steady growth and recent sales momentum over the past few years, the gap between EVs and gasoline-powered cars remains wide.

In 2024, hybrid and electric vehicles are projected to account for roughly 10-15% of total car sales in the U.S., a figure that, though significant, still lags far behind the sales of gas-powered vehicles and follows a Q1 2024 EV market share dip in the U.S., according to recent data. Analysts point to several factors contributing to this slower adoption rate, including higher upfront costs, limited charging infrastructure, and consumer concerns over range anxiety. Additionally, while EVs and hybrids offer lower lifetime operating costs, the initial price difference remains a hurdle for many prospective buyers.

One of the key challenges for EV sales continues to be the perception of cost, even as analyses show they can be better for the planet and often your budget over time. While federal and state incentives have made EVs more affordable, especially for lower-income buyers, the price tag for many electric models remains steep, particularly for higher-end vehicles. Even with government rebates, EVs can still be priced higher than their gasoline counterparts, making them less accessible for middle-class consumers. Many potential buyers are also hesitant to make the switch, unsure if the long-term savings will outweigh the initial investment.

Another critical factor is the limited charging infrastructure in many parts of the country. Though major cities have seen significant improvements in charging stations, rural areas and smaller towns still lack the necessary infrastructure to support widespread EV use. This uneven distribution of charging stations leads to concerns about being stranded in areas without access to fast-charging options. While automakers are working on expanding charging networks, the pace of this development is slow, and EVs won't go mainstream until key problems are fixed according to industry leaders.

Range anxiety is also a continuing issue, despite improvements in battery technology. Though newer electric vehicles can go further on a single charge than ever before, the range of many EVs still doesn't meet the expectations of some drivers, particularly those who regularly take long road trips or live in rural areas. The longer charging times and the necessity of planning routes around charging stations add to the hesitation, especially when gasoline-powered vehicles provide greater convenience and flexibility.

The shift toward EVs is further hindered by the continued dominance of gas-powered cars in the market. Gasoline vehicles benefit from decades of development, an extensive fueling infrastructure, and familiarity with the technology. For many consumers, the convenience, affordability, and ease of use of gas-powered vehicles still outweigh the benefits of switching to an electric alternative. Additionally, with fluctuating fuel prices, many drivers continue to find gas-powered cars relatively cost-effective in terms of daily commuting, especially when compared to the current costs of EV ownership.

Despite these challenges, there is hope for a future shift. The federal government’s push for stricter emissions regulations and tax incentives continues to fuel growth in the electric vehicle market. As automakers ramp up production and more affordable options become available, EV sales are expected to increase in the coming years. Companies like Tesla, Ford, whose hybrids are getting a boost, and General Motors are leading the charge, while new manufacturers like Rivian and Lucid Motors are offering alternatives to traditional gasoline vehicles.

Furthermore, the development of new technologies, such as solid-state batteries and faster charging systems, could help alleviate some of the current drawbacks of electric vehicles. If these advancements reach mass-market production in the next few years, they could help make EVs a more attractive and practical option for consumers, aligning with within-a-decade adoption forecasts from some industry observers.

In conclusion, while hybrid and electric vehicles are growing in popularity, gas-powered vehicles continue to dominate the U.S. car market in 2024. Challenges such as high upfront costs, limited charging infrastructure, and concerns about range persist, making it difficult for many consumers to make the switch to electric even as they ask if it's time to buy an EV in 2024. However, with continued investment in technology and infrastructure, the gap between EVs and gas-powered vehicles could narrow in the years to come.

Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

BC Hydro drought operations address climate change impacts with hydropower scheduling, reservoir management, water conservation, inflow forecasting, and fish habitat protection across the Lower Mainland and Vancouver Island while maintaining electricity generation from storage facilities.

Key Points

BC Hydro drought operations conserve water, protect fish, and sustain hydropower during extended heat and low inflows.

✅ Proactive reservoir releases protect downstream salmon spawning.

✅ Reduced flows at Puntledge, Coquitlam, and Ruskin/Stave facilities.

✅ System relies on northern storage to maintain electricity supply.

BC Hydro is adjusting its operating plans around power generation as extended heat and little forecast rain continue to impact the province, a report says.

“Unpredictable weather patterns related to climate change are expected to continue in the years ahead and BC Hydro is constantly adapting to these evolving conditions, especially after events such as record demand in 2021 that tested the grid,” said the report, titled “Casting drought: How climate change is contributing to uncertain weather and how BC Hydro’s generation system is adapting.”

The study said there is no concern with BC Hydro being able to continue to deliver power through the drought because there is enough water at its larger facilities, even as issues like crypto mining electricity use draw scrutiny from observers.

Still, it said, with no meaningful precipitation in the forecast, its smaller facilities in the Lower Mainland and on Vancouver Island will continue to see record low or near record low inflows for this time of the year.

“In the Lower Mainland, inflows since the beginning of September are ranked in the bottom three compared to historical records,” the report said.

The report said the hydroelectric system is directly impacted by variations in weather and the record-setting, unseasonably dry and warm weather this fall highlights the impacts of climate change, while demand patterns can be counterintuitive, as electricity use even increased during Earth Hour 2018 in some areas, hinting at challenges to come.

It noted symptoms of climate change include increased frequency of extreme events like drought and intense storms, and rapid glacial melt.

“With the extremely hot and dry conditions, BC Hydro has been taking proactive steps at many of our South Coast facilities for months to conserve water to protect the downstream fish habit,” spokesperson Mora Scott said. “We began holding back water in July and August at some facilities anticipating the dry conditions to help ensure we would have water storage for the later summer and early fall salmon spawning.”

Scott said BC Hydro’s reservoirs play an important role in managing these difficult conditions by using storage and planning releases to provide protection to downstream river flows. The reservoirs are, in effect, a battery waiting to be used for power.

While the dry conditions have had an impact on BC Hydro’s watersheds, several unregulated natural river systems — not related to BC Hydro — have fared worse, with rivers drying up and thousands of fish killed, the report said.

BC Hydro is currently seeing the most significant impacts on operations at Puntledge and Campbell River on Vancouver Island as well as Coquitlam and Ruskin/Stave in the Lower Mainland.

To help manage water levels on Vancouver Island, BC Hydro reduced Puntledge River flows by one-third last week and on the Lower Mainland reduced flows at Coquitlam by one-third and Ruskin/Stave by one quarter.

However, the utility company said, there are no concerns about continued power delivery.

“British Columbians benefit from BC Hydro’s integrated, provincial electricity system, which helps send power across the province, including to Vancouver Island, and programs like the winter payment plan support customers during colder months,” staff said.

Most of the electricity generated and used in B.C. is produced by larger facilities in the north and southeast of the province — and while water levels in those areas are below normal levels, there is enough water to meet the province’s power needs, even as additions like Site C's electricity remain a subject of debate among observers.

The Glacier Media investigation found a quarter of BC Hydro's power comes from the Mica, Revelstoke and Hugh Keenleyside dams on the Columbia River. Some 29% comes from dams in the Peace region, including the under-construction Site C project that has faced cost overruns. At certain points of the year, those reservoirs are reliant on glacier water.

Still, BC Hydro remains optimistic.

Forecasts are currently showing little rain in the near-term; however, historically, precipitation and inflows show up by the end of October. If that does not happen, BC Hydro said it would continue to closely track weather and inflow forecasts to adapt its operations to protect fish, while regional cooperation such as bridging with Alberta remains part of broader policy discussions.

Among things BC Hydro said it is doing to adapt are:

Continuously working to improve its weather and inflow forecasting;
Expanding its hydroclimate monitoring technology, including custom-made solutions that have been designed in-house, as well as upgrading snow survey stations to automated, real-time snow and climate stations, and;
Investing in capital projects — like spillway gate replacements — that will increase resiliency of the system to climate change.
