3,000 more families to get help in paying higher bills

Texas Power Grid Reliability faces ERCOT blackouts and winter storm risks; solutions span weatherization, natural gas coordination, PUC-ERCOT reform, capacity market signals, demand response, grid batteries, and geothermal to maintain resilient electricity supply.

Key Points

Texas Power Grid Reliability is ERCOT's ability to keep electricity flowing during extreme weather and demand spikes.

✅ Weatherize power plants and gas supply to prevent freeze-offs

✅ Merge PUC and Railroad Commission for end-to-end oversight

✅ Pay for firm capacity, demand response, and grid storage

The blackouts in February shined a light on the fragile infrastructure that supports modern life. More and more, every task in life requires electricity, and no one is in charge of making sure Texans have enough.

Of the 4.5 million Texans who lost power last winter, many of them also lost heat and at least 100 froze to death. Wi-Fi stopped working and phones soon lost their charges, making it harder for people to get help, find someplace warm to go or to check in on loved ones.

In some places pipes froze, and people couldn’t get water to drink or flush after power and water failures disrupted systems, and low water pressure left some health care facilities unable to properly care for patients. Many folks looking for gasoline were out of luck; pumps run on electricity.

But rather than scouting for ways to use less electricity, we keep plugging in more things. Automatic faucets and toilets, security systems and locks. Now we want to plug in our cars, so that if the grid goes down, we have to hope our Teslas have enough juice to get to Oklahoma.

The February freeze illuminated two problems with electricity sufficiency. First, power plants had mechanical failures, triggering outages for days. But also, Texans demanded a lot more electricity than usual as heaters kicked on because of the cold. The ugly truth is, the Texas power grid probably couldn’t have generated enough electricity to meet demand, even if the plants kept whirring. And that is what should chill us now.

The stories of the people who died because the electricity went out during the freeze are difficult to read. A paletero and cotton-candy vendor well known in Old East Dallas, Leobardo Torres Sánchez, was found dead in his armchair, bundled in quilts beside two heaters that had no power.

Arnulfo Escalante Lopez, 41, and Jose Anguiano Torres, 28, died from carbon monoxide poisoning after using a gas-powered generator to heat their apartment in Garland.

Pramod Bhattarai, 23, a college student from Nepal, died from carbon monoxide after using a charcoal grill to heat his home in Houston, according to news reports. And Loan Le, 75; Olivia Nguyen, 11; Edison Nguyen, 8; and Colette Nguyen, 5, died in Sugar Land after losing control of a fire they started in the fireplace to keep warm.

A 65-year-old San Antonio man with esophageal cancer died after power outages cut off supply from his oxygen machine. And local Abilene media reported that a man died in a local hospital when a loss of water pressure prevented staff from treating him.

Gloria Jones of Hillsboro, 87, was living by herself, healthy and social. According to the Houston Chronicle, as the cold weather descended, she told her friends and family she was fine. But when her children checked on her after she didn’t answer her phone, they found her on the floor beside her bed. Hospital workers tried to warm her, but they soon pronounced her dead.

Officials said in July that 210 people died because of the freezing weather, including those who died in car crashes and other weather-related causes, but that figure will be updated. The Department of State Health Services said most of those deaths were due to hypothermia.

Policy recommendation: Weatherize power plants and fuel suppliers

Texas could have avoided those deaths if power plants had worked properly. It’s mechanically possible to generate electricity in freezing temperatures; the Swedes and Finns have electricity in winter. But preparing equipment for the winter costs money, and now that the Public Utility Commission set new requirements for plant owners to weatherize equipment, we expect better reliability.

The PUC officials certainly expect better performance. Chairman Peter Lake earlier this month promised: “We go into this winter knowing that because of all these efforts the lights will stay on.”

Yet, there’s no matching requirement to weatherize key fuel supplies for natural gas-fired power plants. While the PUC and the Electric Reliability Council of Texas were busy this year coming up with standards and enforcement processes, the Texas Railroad Commission, which regulates oil and gas production, was not.

The Railroad Commission is working to ensure that natural gas producers who supply power plants have filed the proper paperwork so that they do not lose electricity in a blackout, rendering them unable to provide vital fuel. But weatherization regulations will not happen for some months, not in time for this winter.

Policy recommendation: Combine the state’s Public Utility Commission and Railroad Commission into one energy agency

Electricity and natural gas regulators came to realize the importance of natural gas suppliers communicating their electricity needs with the PUC to avoid getting cut off when the fuel is needed the most. Not last year; they realized this ten years ago, when the same thing happened and triggered a day of rolling outages.

Why did it take a decade for the companies regulated by one agency to get their paperwork in order with a separate agency? It makes more sense for a single agency to regulate the entire energy process, from wellhead to lightbulb. (Or well-to-wheel, as cars increasingly need electricity, too.)

Over the years, various legislative sunset commissions have recommended combining the agencies, with different governance suggestions, none of which passed the Legislature. We urge lawmakers in 2023 to take up the idea in earnest, hammer out the governance details, and make sure the resulting agency has the heft and resources to regulate energy in a way that keeps the industry healthy and holds it accountable.

Policy recommendation: Incentivize building more power plants

Regardless, if energy companies in February had operated their equipment exactly right, the lights likely would have still gone out. Perhaps for a shorter period, perhaps in a more shared way, allowing people to keep homes above freezing and phones charged between rolling blackouts. But Texas was heading for trouble.

Before the winter freeze, ERCOT anticipated Texas would have 74,000 MW of power generation capacity for the winter of 2021. That’s less than the usual summer fleet as some plants go down for maintenance in the winter, but sufficient to meet their wildest predictions of winter electricity demand. The power generation on hand for the winter would have met the historic record winter demand, at 65,918 MW. Even in ERCOT’s planning scenario with extreme generator failures, the grid had enough capacity.

But during the second week of February, as weather forecasts became more dire, grid operators began rapidly hiking their estimates of electricity demand. On Valentine’s Day, ERCOT estimated demand would rise to 75,573 MW in the coming week.

Clearly that is more demand than all of Texas’ winter power generation fleet of 74,000 MW could handle. Demand never reached that level because ERCOT turned off service to millions of customers when power plants failed.

This raises questions about whether the Texas grid has enough power plants to remain resilient as climate change brings more frequent bouts of extreme weather and blackout risks across the U.S. Or if we have enough power to grow, as more people and companies, more homes and businesses and manufacturing plants, move to Texas.

What a shame if the Texas Miracle, our robust and growing economy, died because we ran out of electricity.

This is no exaggeration. In November, ERCOT released its seasonal assessment of whether Texas will have enough electricity resources for the coming winter. If weather is normal, yes, Texas will be in good shape. But if extreme weather again pushes Texas to use an inordinate amount of electricity for heat, and if wind and solar output are low, there won’t be enough. In that scenario, even if power plants mostly continue to operate properly, we should brace for outages.

Further, there are few investors planning to build more power plants in Texas, other than solar and wind. Renewable plants have many good qualities, but reliability isn’t one of them. Some investors are building grid-scale batteries, a technology that promises to add reliability to the grid.

How come power plant developers aren’t building more generators, especially with flat electricity demand in many markets today?

Policy recommendation: Incentivize reliability

The Texas electrical grid, independent of the rest of the U.S., operates as a competitive market. No regulator plans a power plant; investors choose to build plants based on expectations of profit.

How it works is, power generators offer their electricity into the market at the price of their choosing. ERCOT accepts the lowest bids first, working up to higher bids as demand for power increases in the course of a day.

The idea is that Texans always get the lowest possible price, and if prices rise high, investors will build more power plants. Basic supply and demand. When the market was first set up, this worked pretty well, because the big, reliable baseload generators, the coal and nuclear industries, were the cheapest to operate and bid their power at prices that kept them online all the time. The more agile natural gas-fired plants ramped up and down to meet demand minute-by-minute, at higher prices.

Renewable energy disrupts the market in ways that are great, generating cheap, clean power that has forced some high-polluting coal plants to mothball. But the disruption also undermines reliability. Wind and solar plants are the cheapest and quickest power generation to build and they have the lowest operating cost, allowing them to bid very low prices into the power market. Wind tends to blow hardest in West Texas at night, so the abundance of wind turbines has pushed many of those old baseload plants out of the market.

That’s how markets work, and we’re not crying for coal plant operators. But ERCOT has to figure out how to operate the market differently to keep the lights on.

The PUC announced a slew of electricity market reforms last week to address this very problem, including new to market pricing and an emergency reliability service for ERCOT to contract for more back-up power. These changes cost money, but failing to make any changes could cost more lives.

Texas became the No. 1 wind state thanks in part to a smart renewable energy credit system that created financial incentives to erect wind turbines. But those credits mean that sometimes at night, wind generators bid electricity into the market at negative prices, because they will make money off of the renewable energy credits.

It’s time for the Legislature to review the credit program to determine if it’s still needed, of a similar program could be added to incentivize reliability. The market-based program worked better than anyone could have expected to produce clean energy. Why not use this approach to create what we need now: clean and reliable energy?

We were pleased that PUC commissioners discussed last week an idea that would create a market for reliable power generation capacity by adding requirements that power market participants meet a standard of reliability guarantees.

A market for reliable electricity capacity will cost more, and we hope regulators keep the requirements as modest as possible. Renewable requirements were modest, but turned out to be powerful in a competitive market.

We expect a reliability program to be flexible enough that entrepreneurs can participate with new technology, such as batteries or geothermal energy or something that hasn’t been invented yet, rather than just old reliable fossil fuels.

We also welcome the PUC’s review of pricing rules for the market. Commissioners intend for a new pricing formula to offer early price signals of pending scarcity, to allow time for industrial customers to reduce consumption or suppliers to ramp up. This is intriguing, but we hope the final implementation keeps market interventions at a minimum.

We witnessed in February a scenario in which extremely high prices on the power market did nothing to attract more electricity into the market. Power plants broke down; there was no way to generate more power, no matter how high market prices went. So the PUC was silly to intervene in the market and keep prices artificially high; the outcome was billions of dollars of debt and a proposed electricity market bailout that electricity customers will end up paying.

Nor did this PUC pricing intervention prompt power generation developers to say: “I tell you what, let’s build more plants in Texas.” In the next few years, ERCOT can expect more solar power generation to come online, but little else.

Natural gas plant operators have told the PUC that market price signals show that a new plant wouldn’t be profitable. Natural gas plants are cheaper and faster to build than nuclear reactors; if those developers cannot figure out how to make money, then the prospect of a new nuclear reactor in Texas is a fantasy, even setting aside the environmental and political opposition.

Policy proposal: Use less energy

Politicians like to imagine that technology will solve our energy problem. But the quickest, cheapest, cleanest solution to all of our energy problems is to use less. Investing some federal infrastructure money to make homes more energy efficient would cut energy use, and could help homes retain heat in an emergency.

The PUC’s plan to offer more incentives for major power users to reduce demand in a grid emergency is a good idea. Bravo – next let’s take this benefit to the masses.

Upgrading building codes to require efficiency for office buildings and apartments can help, and might have prevented the frozen pipes in so many multifamily housing units that left people without water.

When North Texas power-line utility Oncor invested in smart grid technology in past decades, part of the promise was to help users reduce demand when electricity prices rise or in emergencies. A review and upgrade of the smart technology could allow more customers to benefit from discounts in exchange for turning things off when electricity supply is tight.

Problem is, we seem to be going in the opposite direction as consumers. Forget turning off the TV and unplugging the coffee machine as we leave the house each morning; now everything is always-on and always connected to Wi-Fi. Our appliances, electronics and the services that operate them can text us when anything interesting happens, like the laundry finishes or somebody opens the patio door or the first season of Murder She Wrote is available for streaming.

As Texans plug in electric vehicles, we will need even more power generation capacity. Researchers at the University of Texas at Austin estimated that if every Texan switched to an electric vehicle, demand for electricity would rise about 30%.

Texans will need to think realistically and rationally about where that electricity is going to come from. Before we march toward a utopian vision of an all-electric world, we need to make sure we have enough electricity.

Getting this right is a matter of life and death for each of one us and for Texas.

Western Washington Bomb Cyclone unleashed gale-force winds, torrential rain, and coastal flooding, causing massive power outages from Seattle to Tacoma; storm surge, downed trees, and blocked roads hindered emergency response and infrastructure repairs.

Key Points

A rapidly deepening storm with severe winds, rain, flooding, and major power outages across Western Washington.

✅ Rapid barometric pressure drop intensified the system

✅ Gale-force winds downed trees and power lines

✅ Coastal flooding and storm surge disrupted transport

A powerful "bomb cyclone" recently hit Western Washington, causing widespread destruction across the region. The intense storm left more than half a million residents without power, similar to B.C. bomb cyclone outages seen to the north, with outages affecting communities from Seattle to Olympia. This weather phenomenon, marked by a rapid drop in atmospheric pressure, unleashed severe wind gusts, heavy rain, and flooding, causing significant disruption to daily life.

The bomb cyclone, which is a rapidly intensifying storm, typically features a sharp drop in barometric pressure over a short period of time. This creates extreme weather conditions, including gale-force winds, torrential rain, and coastal flooding, as seen during California storm impacts earlier in the season. In Western Washington, the storm struck just as the region was beginning to prepare for the winter season, catching many off guard with its strength and unpredictability.

The storm's impact was immediately felt as high winds downed trees, power lines, and other infrastructure. By the time the worst of the storm had passed, utility companies had reported widespread power outages, with more than 500,000 customers losing electricity. The outages were particularly severe in areas like Seattle, Tacoma, and the surrounding communities. Crews worked tirelessly in difficult conditions to restore power, but many residents faced extended outages, underscoring US grid climate vulnerabilities that complicate recovery efforts, with some lasting for days due to the scope of the damage.

The power outages were accompanied by heavy rainfall, leading to localized flooding. Roads were inundated, making it difficult for first responders and repair crews to reach affected areas. Emergency services were stretched thin as they dealt with downed trees, blocked roads, and flooded neighborhoods. In some areas, floodwaters reached homes, forcing people to evacuate. In addition, several schools were closed, and public transportation services were temporarily halted, leaving commuters stranded and businesses unable to operate.

As the storm moved inland, its effects continued to be felt. Western Washington’s coastal regions were hammered by high waves and storm surges, further exacerbating the damage. The combination of wind and rain also led to hazardous driving conditions, prompting authorities to advise people to stay off the roads unless absolutely necessary.

While power companies worked around the clock to restore electricity, informed by grid resilience strategies that could help utilities prepare for future events, challenges persisted. Fallen trees and debris blocked access to repair sites, and the sheer number of outages made it difficult for crews to restore power quickly. Some customers were left in the dark for days, forced to rely on generators, candles, and other makeshift solutions. The storm's intensity left a trail of destruction, requiring significant resources to address the damages and rebuild critical infrastructure.

In addition to the immediate impacts on power and transportation, the bomb cyclone raised important concerns about climate change and the increasing frequency of extreme weather events. Experts note that storms like these are becoming more common, with rapid intensification leading to more severe consequences and compounding pressures such as extreme-heat electricity costs for households. As the planet warms, scientists predict that such weather systems will continue to grow in strength, posing greater challenges to cities and regions that are not always prepared for such extreme events.

In the aftermath of the storm, local governments and utility companies faced the daunting task of not only restoring services but also assessing the broader impact of the storm on communities. Many areas, especially those hit hardest by flooding and power outages, will require substantial recovery efforts. The devastation of the bomb cyclone highlighted the vulnerability of infrastructure in the face of rapidly changing weather patterns and water availability, as seen in BC Hydro drought adaptations nearby, and reinforced the need for greater resilience in the face of future storms.

The storm's impact on the Pacific Northwest is a reminder of the power of nature and the importance of preparedness. As Western Washington recovers, there is a renewed focus on strengthening infrastructure, including expanded renewable electricity to diversify supply, improving emergency response systems, and ensuring that communities are better equipped to handle the challenges posed by increasingly severe weather events. For now, residents remain hopeful that the worst is behind them and are working together to rebuild and prepare for whatever future storms may bring.

The bomb cyclone has left an indelible mark on Western Washington, but it also serves as a call to action for better preparedness, more robust infrastructure, and a greater focus on combating climate change to mitigate the impact of such extreme weather in the future.

Cannes Film Festival Power Outage disrupts Alpes-Maritimes as an electrical substation fire and a fallen high-voltage line trigger blackouts; arson probe launched, grid resilience tested, traffic and trains snarled, Palais des Festivals on backup power.

Key Points

A May 24, 2025 blackout in Cannes disrupting events, under arson probe, exposing grid risks across Alpes-Maritimes.

✅ Substation fire and fallen high-voltage line triggered blackouts

✅ Palais des Festivals ran on independent backup power

✅ Authorities probe suspected arson; security measures reviewed

A significant power outage on May 24, 2025, disrupted the final day of the Cannes Film Festival in southeastern France. The blackout, which affected approximately 160,000 households in the Alpes-Maritimes region, including the city of Cannes, occurred just hours before the highly anticipated Palme d'Or ceremony. French authorities are investigating the possibility that the outage was caused by arson.

Details of the Outage

The power disruption began early on Saturday morning with a fire at an electrical substation near Cannes. This incident weakened the local power grid. Shortly thereafter, a high-voltage line fell at another location, further exacerbating the situation. The combined events led to widespread power outages, affecting not only the festival but also local businesses, traffic systems, and public transportation, echoing Heathrow Airport outage warnings raised days before a separate disruption. Traffic lights in parts of Cannes and the nearby city of Antibes stopped working, leading to traffic jams and confusion in city centers. Most shops along the Croisette remained closed, and local food kiosks were only accepting cash. Train service in Cannes was also disrupted. 

Impact on the Festival

Despite the challenges, festival organizers managed to keep the main venue, the Palais des Festivals, operational by switching to an independent power supply. They confirmed that all scheduled events and screenings, including the Closing Ceremony, would proceed as planned, a reminder of how grid operators sometimes avoid rolling blackouts to keep essential services running. The power was restored around 3 p.m. local time, just hours before the ceremony, allowing music to resume and the event to continue without further incident.

Investigations and Suspected Arson

French authorities, including the national gendarmerie, are investigating the possibility that the power outage was the result of arson, aligning with grid attack warnings issued by intelligence services. The prefect for the Alpes-Maritimes region, Laurent Hottiaux, condemned the "serious acts of damage to electrical infrastructures" and stated that all resources are mobilized to identify, track down, arrest, and bring to justice the perpetrators of these acts.

While investigations are ongoing, no official conclusions have been drawn regarding the cause of the outage. Authorities are working to determine whether the incidents were isolated or part of a coordinated effort, a question that also arises when utilities implement PG&E wildfire shutoffs to prevent cascading damage.

Broader Implications

The power outage at the Cannes Film Festival underscores the vulnerability of critical infrastructure to potential acts of sabotage. While the immediate impact on the festival was mitigated, the incident raises concerns about the resilience of energy systems, especially during major public events, and amid severe weather like a B.C. bomb cyclone that leaves tens of thousands without power. It also highlights the importance of having contingency plans in place to ensure the continuity of essential services in the face of unexpected disruptions.

As investigations continue, authorities are urging the public to remain vigilant and report any suspicious activities, while planners also prepare for storm-driven outages that compound emergency response. The outcome of this investigation may have implications for future security measures at large-scale events and the protection of critical infrastructure.

While the Cannes Film Festival was able to proceed with its closing events, the power outage serves as a reminder of the potential threats to public safety, as seen when a Western Washington bomb cyclone left hundreds of thousands without power, and the importance of robust security measures to safeguard against such incidents.

2022 U.S. Power Outage Statistics show lower SAIDI as fewer major events hit, with SAIFI trends, electric reliability, outage duration and frequency shaped by hurricanes, winter storms, vegetation, and utility practices across states.

Key Points

They report SAIDI and SAIFI for 2022, showing outage duration, frequency, and impacts of major weather events.

✅ 2022 SAIDI averaged 5.6 hours; SAIFI averaged 1.4 interruptions.

✅ Fewer major events lowered outage duration versus 2021.

✅ Hurricanes and winter storms drove long outages in several states.

In 2022, U.S. electricity consumers on average experienced about 5.5 hours of power disruptions, a decrease from nearly two hours compared to 2021. This information comes from the latest Annual Electric Power Industry Report. The reduction in yearly power interruptions primarily resulted from fewer significant events in 2022 compared to the previous year, and utility disaster planning continues to support grid resilience as severe weather persists.

Since 2013, excluding major events, the annual average duration of power interruptions has consistently hovered around two hours. Factors contributing to major power disruptions include weather-related incidents, vegetation interference near power lines, and specific utility practices, while pandemic-related grid operations influenced workforce planning more than outage frequency. To assess the reliability of U.S. electric utilities, two key indexes are utilized:

• The System Average Interruption Duration Index (SAIDI) calculates the total length (in hours) an average customer endures non-brief power interruptions over a year.
• The System Average Interruption Frequency Index (SAIFI) tracks the number of times interruptions occur.

The influence of major events on electrical reliability is gauged by comparing affected states' SAIDI and SAIFI values against the U.S. average, which was 5.6 hours of outages and 1.4 outages per customer in 2022. The year witnessed 18 weather-related disasters in the U.S., each resulting in over $1 billion in damages, and COVID-19 grid assessments indicated the electricity system was largely safe from pandemic impacts. Noteworthy major events include:

• Hurricane Ian in September 2022, leaving over 2.6 million Floridian customers without electricity, with restoration in some areas taking weeks rather than days.
• Hurricane Nicole in November 2022, causing over 300,000 Florida customers to lose power.
• Winter Storm Elliott in December 2022, affecting over 1.5 million customers in multiple states including Texas where utilities struggled after Hurricane Harvey to restore service, and Florida, and bringing up to four feet of snow in parts of New York.

In 2022, states like Florida, West Virginia, Maine, Vermont, and New Hampshire experienced the most prolonged power interruptions, with New Hampshire averaging 10.3 hours and Florida 19.1 hours, and FPL's Irma storm response illustrates how restoration can take days or weeks in severe cases. Conversely, the District of Columbia, Delaware, Rhode Island, Nebraska, and Iowa had the shortest total interruptions, with the District of Columbia averaging just 34 minutes and Iowa 85 minutes.

The frequency of outages, unlike their duration, is more often linked to non-major events. Across the nation, Alaska recorded the highest number of power disruptions per customer (averaging 3.5), followed by several heavily forested states like Tennessee and Maine. Power outages due to falling tree branches are common, particularly during winter storms that burden tree limbs and power lines, as seen in a North Seattle outage affecting 13,000 customers. The District of Columbia stood out with the shortest and fewest outages per customer.

Texas ERCOT Power Grid leads U.S. wind generation yet faces isolated interconnection, FERC exemption, and high industrial energy use, with distinct electricity and natural gas prices managed by a single balancing authority.

Key Points

The state-run interconnection that balances Texas electricity, isolated from FERC oversight and other U.S. grids.

✅ Largest U.S. wind power producer, high industrial demand

✅ Operates one balancing authority, independent interconnection

✅ Pays lower electricity, higher natural gas vs national average

For nearly two decades, the Lone Star State has generated more wind-sourced electricity than any other state in the U.S., according to the Energy Information Administration, or EIA.

In 2022, EIA reported Texas produced more electricity than any other state and generated twice as much as second-place Florida.

However, Texas also leads the country in another category. According to EIA, Texas is the largest energy-consuming state in the nation across all sectors with more than half of the state’s energy being used by the industrial sector.

As of May 2023, Texas residents paid 43% more for natural gas and around 10% less for electricity compared to the national average, according to EIA, and in competitive areas shopping for electricity is getting cheaper as well. Commercial and industrial sectors on average for the same month paid 25% less for electricity compared to the national average.

U.S. electric system compared to Texas
The U.S. electric system is essentially split into three regions called interconnections and are managed by a total of 74 entities called balancing authorities that ensure that power supply and demand are balanced throughout the region to prevent the possibility of blackouts, according to EIA.

The three regions (Interconnections):

Eastern Interconnection: Covers all U.S. states east of the Rocky Mountains, a portion of northern Texas, and consists of 36 balancing authorities.
Western Interconnection: Covers all U.S. states west of the Rockies and consists of 37 balancing authorities.
ERCOT: Covers the majority of Texas and consists of one balancing authority (itself).

During the 2021 winter storm, Texas electric cooperatives were credited with helping maintain service in many communities.

“ERCOT is unique in that the balancing authority, interconnection, and the regional transmission organization are all the same entity and physical system,” according to EIA, a structure often discussed in analyses of Texas power grid challenges today.

With this being the case, Texas is the only state in the U.S. that balances itself, the only state that is not subject to the jurisdiction of the Federal Energy Regulatory Commission, or FERC, and the only state that is not synchronously interconnected to the grid in the rest of the United States in the event of tight grid conditions, highlighting ongoing discussions about improving Texas grid reliability before peak seasons, according to EIA.

Every other state in the U.S. is connected to a web of multiple balancing authorities that contribute to ensuring power supply and demand are met.

California, for example, was the fourth largest electricity producer and the third largest electricity consumer in the nation in 2022, according to EIA, and California imports the most electricity from other states while Pennsylvania exports the most.

Although California produces significantly less electricity than Texas, it has the ability to connect with more than 10 neighboring balancing authorities within the Western Interconnection to interchange electricity, a dynamic that can see clean states importing dirty electricity under certain market conditions. ERCOT being independent only has electricity interchange with two balancing authorities, one of which is in Mexico.

Regardless of Texas’ unique power structure compared to the rest of the nation, the vast majority of the U.S. risked electricity supplies during this summer’s high heat, as outlined in severe heat blackout risks reports, according to EIA.

High-Temperature Superconducting Cables enable lossless, high-voltage, underground transmission for grid modernization, linking renewable energy to cities with liquid nitrogen cooling, boosting efficiency, cutting emissions, reducing land use, and improving resilience against disasters and extreme weather.

Key Points

Liquid-nitrogen-cooled power cables delivering electricity with near-zero losses, lower voltage, and greater resilience.

✅ Near-lossless transmission links renewables to cities efficiently

✅ Operate at lower voltage, reducing substation size and cost

✅ Underground, compact, and resilient to extreme weather events

For most of us, transmitting power is an invisible part of modern life. You flick the switch and the light goes on.

But the way we transport electricity is vital. For us to quit fossil fuels, we will need a better grid, with macrogrid planning connecting renewable energy in the regions with cities.

Electricity grids are big, complex systems. Building new high-voltage transmission lines often spurs backlash from communities, as seen in Hydro-Que9bec power line opposition over aesthetics and land use, worried about the visual impact of the towers. And our 20th century grid loses around 10% of the power generated as heat.

One solution? Use superconducting cables for key sections of the grid. A single 17-centimeter cable can carry the entire output of several nuclear plants. Cities and regions around the world have done this to cut emissions, increase efficiency, protect key infrastructure against disasters and run powerlines underground. As Australia prepares to modernize its grid, it should follow suit with smarter electricity infrastructure initiatives seen elsewhere. It's a once-in-a-generation opportunity.

What's wrong with our tried-and-true technology?
Plenty.

The main advantage of high voltage transmission lines is they're relatively cheap.

But cheap to build comes with hidden costs later. A survey of 140 countries found the electricity currently wasted in transmission accounts for a staggering half-billion tons of carbon dioxide—each year.

These unnecessary emissions are higher than the exhaust from all the world's trucks, or from all the methane burned off at oil rigs.

Inefficient power transmission also means countries have to build extra power plants to compensate for losses on the grid.

Labor has pledged A$20 billion to make the grid ready for clean energy, and international moves such as US-Canada cross-border approvals show the scale of ambition needed. This includes an extra 10,000 kilometers of transmission lines. But what type of lines? At present, the plans are for the conventional high voltage overhead cables you see dotting the countryside.

System planning by Australia's energy market operator shows many grid-modernizing projects will use last century's technologies, the conventional high voltage overhead cables, even as Europe's HVDC expansion gathers pace across its network. If these plans proceed without considering superconductors, it will be a huge missed opportunity.

How could superconducting cables help?
Superconduction is where electrons can flow without resistance or loss. Built into power cables, it holds out the promise of lossless electricity transfer, over both long and short distances. That's important, given Australia's remarkable wind and solar resources are often located far from energy users in the cities.

High voltage superconducting cables would allow us to deliver power with minimal losses from heat or electrical resistance and with footprints at least 100 times smaller than a conventional copper cable for the same power output.

And they are far more resilient to disasters and extreme weather, as they are located underground.

Even more important, a typical superconducting cable can deliver the same or greater power at a much lower voltage than a conventional transmission cable. That means the space needed for transformers and grid connections falls from the size of a large gym to only a double garage.

Bringing these technologies into our power grid offers social, environmental, commercial and efficiency dividends.

Unfortunately, while superconductors are commonplace in Australia's medical community (where they are routinely used in MRI machines and diagnostic instruments) they have not yet found their home in our power sector.

One reason is that superconductors must be cooled to work. But rapid progress in cryogenics means you no longer have to lower their temperature almost to absolute zero (-273℃). Modern "high temperature" superconductors only need to be cooled to -200℃, which can be done with liquid nitrogen—a cheap, readily available substance.

Overseas, however, they are proving themselves daily. Perhaps the most well-known example to date is in Germany's city of Essen. In 2014, engineers installed a 10 kilovolt (kV) superconducting cable in the dense city center. Even though it was only one kilometer long, it avoided the higher cost of building a third substation in an area where there was very limited space for infrastructure. Essen's cable is unobtrusive in a meter-wide easement and only 70cm below ground.

Superconducting cables can be laid underground with a minimal footprint and cost-effectively. They need vastly less land.

A conventional high voltage overhead cable requires an easement of about 130 meters wide, with pylons up to 80 meters high to allow for safety. By contrast, an underground superconducting cable would take up an easement of six meters wide, and up to 2 meters deep.

This has another benefit: overcoming community skepticism. At present, many locals are concerned about the vulnerability of high voltage overhead cables in bushfire-prone and environmentally sensitive regions, as well as the visual impact of the large towers and lines. Communities and farmers in some regions are vocally against plans for new 85-meter high towers and power lines running through or near their land.

Climate extremes, unprecedented windstorms, excessive rainfall and lightning strikes can disrupt power supply networks, as the Victorian town of Moorabool discovered in 2021.

What about cost? This is hard to pin down, as it depends on the scale, nature and complexity of the task. But consider this—the Essen cable cost around $20m in 2014. Replacing the six 500kV towers destroyed by windstorms near Moorabool in January 2020 cost $26 million.

While superconducting cables will cost more up front, you save by avoiding large easements, requiring fewer substations (as the power is at a lower voltage), and streamlining approvals.

Where would superconductors have most effect?
Queensland. The sunshine state is planning four new high-voltage transmission projects, to be built by the mid-2030s. The goal is to link clean energy production in the north of the state with the population centers of the south, similar to sending Canadian hydropower to New York to meet demand.

Right now, there are major congestion issues between southern and central Queensland, and subsea links like Scotland-England renewable corridors highlight how to move power at scale. Strategically locating superconducting cables here would be the best location, serving to future-proof infrastructure, reduce emissions and avoid power loss.
