Grain farmer Mike Doyle has grown to love the big, spindly wind turbines that rise from his central Illinois prairie.

Their blades, many more than 100 feet, cut the wind with a low, rhythmic whooshing noise. Not too long ago, he admired a rainbow arching over them.

Doyle's a little embarrassed when he describes the scene, but he's sincere. "If that wasn't the most beautiful sight I've ever seen."

The money's not bad either.

Doyle is paid just over $35,000 a month for the seven wind turbines in his soybean and corn fields. Those turbines and thousands others across the Midwest the past few years were part of an unprecedented build-out for the wind-power industry.

That expansion is now drastically slowing as financing dries up for many projects because of the global economic crisis. Companies that bankrolled much of the boom — the insurer AIG, now-bankrupt financial service company Lehman Brothers and Wachovia Corp. — are among the meltdown's biggest losers.

"There's definitely a lot of, obviously, upheaval," said Ric O'Connell, a renewable energy consultant with Black & Veatch Corp., an Overland Park, Kan.-based engineering and construction company. "I would definitely think in 2009 there are going to be projects that are going to be delayed."

Already some developers are scaling back.

Noble Environmental Power, an Essex, Conn.-based developer with projects from Maine to Michigan, Wyoming and Texas, said last month it is cutting back development next year and laying off workers.

Florida Power and Light, another major developer, has said it will slow down in 2009, too.

And last month oil tycoon T. Boone Pickens famously delayed his massive Texas wind-farm plans, alternately blaming a lack of financing and declining petroleum prices.

The country's wind-power capacity has increased by 500 percent in the past 10 years, to just over 21,000 megawatts, according to the American Wind Industry Association. A one-megawatt wind turbine can generate enough electricity in a year to power up to 300 homes for a year.

Even now, there are 86 wind-farm projects under construction around the country, the association said. Fifty-seven are in the windy states in country's midsection from Texas to the Dakotas, Minnesota and Illinois.

About 60 percent of the new capacity has been built since the beginning of 2005 and driven by factors ranging from renewable energy to, until recently, high oil and natural gas prices.

But the most important of those factors are federal tax credits and state mandates requiring that some power be generated by sources such as wind or the sun.

The mandates, which exist in 28 states, are responsible for about two-thirds of the market for wind energy, according to Hans Detweiler, director of state policy for the American Wind Energy Association.

And the tax credits generate much of the money to build.

Firms like AIG, Lehman and Wachovia helped finance many projects by taking short-term ownership in exchange for the credits to help offset their own income.

Those three were among the biggest investors in the industry. Now, AIG is trying to survive the financial meltdown, Wachovia is being bought by Citigroup and Lehman Brothers filed for bankruptcy this year before being sold.

Even healthier companies that have helped finance the wind boom are being weighed down by the economy, meaning they aren't making as much money so they don't need the tax credits, said Peter Maloney, chief editor at Platts Global Power Report, an energy-industry magazine.

The investment money flowing into the wind-energy business flattened this year for the first time in several years, at about $5.5 billion dollars, said industry analyst Joshua Magee of Emerging Energy Research.

And J.P. Morgan, another of those major investors, is predicting that flow will fall by more than 20 percent in 2009, to about $4 billion.

The projects most in jeopardy are those that are in their infancy — the ones in which developers were looking for sites and financing when the economic tsunami started.

"If you're talking about a project that's planning to enter construction in 2009, there has been a very slow deal flow... since the financial crisis began," said Magee, adding that situation for many smaller developers is "fairly dire."

No one tracks just how many projects are in the development stages, between planning and building, but industry analysts say there are many.

One company, Chicago-based Midwest Wind Energy has one project under construction in Illinois and another it hopes to start building next year, president and founder Stefan Noe said.

He's optimistic that those and other projects will happen, in part because the company works with a financially healthy subsidiary of Edison International, the utility giant, to finance its projects.

And, with President-elect Barack Obama pledging financial support for renewable energy, Noe thinks wind power could be on the verge of significant growth, but only if the country's faltering economy doesn't get in the way.

"If there's any concern I have, it's that the capital markets don't open up quickly enough, because there are certainly plenty of projects in development," he said. "Eventually, those markets need to free up for anybody to continue to successfully develop these projects because they are capital intensive."

Illinois has at least a dozen or so projects that haven't started construction. The state is the country's eighth biggest wind-power producer with 11 wind farms generating about 744 megawatts of power, according to the Wind Energy Association.

Texas is tops, with 6,300 megawatts of existing capacity spread over dozens of wind farms.

Farms that are built mean mini windfalls for land owners like Doyle, and for local governments.

McLean County, where Doyle lives, will be paid $288,000 next year in taxes for the turbines, county administrator John Zeunik said.

"Then obviously for the school districts, there's more," he said.

That money may be harder to come by as building slows.

But O'Connel, from Black & Veatch, is optimistic that the hurdles will be worked out, but not necessarily in the next year. The companies that were pushing wind-energy development, he said, are no longer able to do so.

"Some of those financial institutions have gone bankrupt," he said, "and none of those people are making money.

"So it's going to be much more difficult to get financing in 2009."

Climate change: Electrical industry's 'dirty secret' boosts warming

Sulphur Hexafluoride (SF6) Emissions drive rising greenhouse gas impacts in electrical switchgear, power grids, and renewables, with extreme global warming potential, long atmospheric lifetime, and leakage risks challenging climate targets and grid decarbonization.

 

Key Points

SF6 emissions are leaks from electrical switchgear and grids, a high-GWP gas with ~1,000-year lifetime.

✅ 23,500x CO2 global warming potential (GWP)

✅ Leaks from switchgear, breakers, gas-insulated substations

✅ Clean air and vacuum alternatives emerging for MV/HV

 

Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.

But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

Levels are rising as an unintended consequence of the green energy boom and the broader global energy transition worldwide.

Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations.

It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities.

It prevents electrical accidents and fires.

However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).

Just one kilogram of SF6 warms the Earth to the same extent as 24 people flying London to New York return.

It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.

 

So why are we using more of this powerful warming gas?

The way we make electricity around the world is changing rapidly, with New Zealand's push to electrify in its energy system.

Where once large coal-fired power stations brought energy to millions, the drive to combat climate change and to move away from coal means they are now being replaced by mixed sources of power including wind, solar and gas.

This has resulted in many more connections to the electricity grid, and with EU electricity use could double by 2050, a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.

Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.

"As renewable projects are getting bigger and bigger, we have had to use it within wind turbines specifically," said Costa Pirgousis, an engineer with Scottish Power Renewables on its new East Anglia wind farm, which doesn't use SF6 in turbines.

"As we are putting in more and more turbines, we need more and more switchgear and, as a result, more SF6 is being introduced into big turbines off shore.

"It's been proven for years and we know how it works, and as a result it is very reliable and very low maintenance for us offshore."

 

How do we know that SF6 is increasing?

Across the entire UK network of power lines and substations, there are around one million kilograms of SF6 installed.

A study from the University of Cardiff found that across all transmission and distribution networks, the amount used was increasing by 30-40 tonnes per year.

This rise was also reflected across Europe with total emissions from the 28 member states in 2017 equivalent to 6.73 million tonnes of CO2. That's the same as the emissions from 1.3 million extra cars on the road for a year.

Researchers at the University of Bristol who monitor concentrations of warming gases in the atmosphere say they have seen significant rises in the last 20 years.

"We make measurements of SF6 in the background atmosphere," said Dr Matt Rigby, reader in atmospheric chemistry at Bristol.

"What we've seen is that the levels have increased substantially, and we've seen almost a doubling of the atmospheric concentration in the last two decades."

 

How does SF6 get into the atmosphere?

The most important means by which SF6 gets into the atmosphere is from leaks in the electricity industry.

Electrical company Eaton, which manufactures switchgear without SF6, says its research indicates that for the full life-cycle of the product, leaks could be as high as 15% - much higher than many other estimates.

Louis Schaeffer, electrical business manager at Eaton, said: "The newer gear has very low leak rates but the key question is do you have newer gear?

"We looked at all equipment and looked at the average of all those leak rates, and we didn't see people taking into account the filling of the gas. Plus, we looked at how you recycle it and return it and also included the catastrophic leaks."

 

How damaging to the climate is this gas?

Concentrations in the atmosphere are very small right now, just a fraction of the amount of CO2 in the air.

However, the global installed base of SF6 is expected to grow by 75% by 2030, as data-driven electricity demand surges worldwide.

Another concern is that SF6 is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate.

Developed countries are expected to report every year to the UN on how much SF6 they use, but developing countries do not face any restrictions on use.

Right now, scientists are detecting concentrations in the atmosphere that are 10 times the amount declared by countries in their reports. Scientists say this is not all coming from countries like India, China and South Korea.

One study found that the methods used to calculate emissions in richer countries "severely under-reported" emissions over the past two decades.

 

Why hasn't this been banned?

SF6 comes under a group of human-produced substances known as F-gases. The European Commission tried to prohibit a number of these environmentally harmful substances, including gases in refrigeration and air conditioning, back in 2014.

 

But they faced strong opposition from industries across Europe.

"In the end, the electrical industry lobby was too strong and we had to give in to them," said Dutch Green MEP Bas Eickhout, who was responsible for the attempt to regulate F-gases.

"The electric sector was very strong in arguing that if you want an energy transition, and you have to shift more to electricity, you will need more electric devices. And then you also will need more SF6.

"They used the argument that otherwise the energy transition would be slowed down."

 

What do regulator and electrical companies say about the gas?

Everyone is trying to reduce their dependence on the gas, and US control efforts suggest targeted policies can drive declines, as it is universally recognised as harmful to the climate.

In the UK, energy regulator Ofgem says it is working with utilities to try to limit leaks of the gas.

"We are using a range of tools to make sure that companies limit their use of SF6, a potent greenhouse gas, where this is in the interest of energy consumers," an Ofgem spokesperson told BBC News.

"This includes funding innovation trials and rewarding companies to research and find alternatives, setting emissions targets, rewarding companies that beat those targets, and penalising those that miss them."

 

Are there alternatives - and are they very expensive?

The question of alternatives to SF6 has been contentious over recent years.

For high-voltage applications, experts say there are very few solutions that have been rigorously tested.

"There is no real alternative that is proven," said Prof Manu Haddad from the school of engineering at Cardiff University.

"There are some that are being proposed now but to prove their operation over a long period of time is a risk that many companies don't want to take."

Medium voltage operations there are several tried-and-tested materials. Some in the industry say that the conservative nature of the electrical industry is the key reason that few want to change to a less harmful alternative.

 

"I will tell you, everyone in this industry knows you can do this; there is not a technical reason not to do it," said Louis Schaffer from Eaton.

"It's not really economic; it's more a question that change takes effort and if you don't have to, you won't do it."

 

Some companies are feeling the winds of change

Sitting in the North Sea some 43km from the Suffolk coast, Scottish Power Renewables has installed one of world's biggest wind farms, in line with a sustainable electric planet vision, where the turbines will be free of SF6 gas.

East Anglia One will see 102 of these towering generators erected, with the capacity to produce up to 714MW (megawatts) of power by 2020, enough to supply half a million homes.

Previously, an installation like this would have used switchgear supplied with SF6, to prevent the electrical accidents that can lead to fires.

Each turbine would normally have contained around 5kg of SF6, which, if it leaked into the atmosphere, would add the equivalent of around 117 tonnes of carbon dioxide. This is roughly the same as the annual emissions from 25 cars.

"In this case we are using a combination of clean air and vacuum technology within the turbine. It allows us to still have a very efficient, reliable, high-voltage network but to also be environmentally friendly," said Costa Pirgousis from Scottish Power Renewables.

"Once there are viable alternatives on the market, there is no reason not to use them. In this case, we've got a viable alternative and that's why we are using it."

But even for companies that are trying to limit the use of SF6, there are still limitations. At the heart of East Anglia One sits a giant offshore substation to which all 102 turbines will connect. It still uses significant quantities of the highly warming gas.

 

What happens next ?

The EU will review the use of SF6 next year and will examine whether alternatives are available. However, even the most optimistic experts don't think that any ban is likely to be put in place before 2025.

Power bill cut for 22m Thailand houses

Thailand Covid-19 Electricity Bill Relief offers energy subsidies, tariff cuts, and free power for small meters, helping work-from-home users as authorities waive charges and discount kWh rates via EGAT, MEA, PEA for three months.

 

Key Points

Program waiving or cutting household electricity bills for 22 million homes in March-May, easing work-from-home costs.

? Free power for meters <= 5 amps; up to 10M homes

? Up to 800 kWh: pay February rate; above, 50% discount

? >3,000 kWh: 30% discount; program valid March-May

 

The Thailand cabinet has formally approved energy authorities' decision to either waive or cut electricity charges, similar to B.C. electricity relief measures, for 22 million households where people are working at home because of the coronavirus disease.

Energy Minister Sontirat Sontijirawong said after the cabinet meeting on Tuesday that the ministers acknowledged the step taken by from the Energy Regulatory Commission, the Electricity Generating Authority of Thailand, the Metropolitan Electricity Authority and the Provincial Electricity Authority and noted parallels with Ontario's COVID-19 hydro plan rolled out to support ratepayers.

The measure would be valid for three months, from March to May, and cover 22 million households. It would cost the state 23.68 billion baht in lost revenue, he said, a pattern also seen with Ontario rate reductions affecting provincial revenues.


"The measure reduces the electricity charges burden on households. It is the cost of living of the people who are working from home to support the government's control of Covid-19," Mr Sontirat said.

The business sector also wants similar assistance, echoing sentiments from Ontario manufacturers during recent price reduction efforts. He said their requests were being considered.

Free electricity is extended to households with a power meter of no more than 5 amps. Up to 10 million households are expected to benefit, although issues like electricity payment challenges in India highlight different market contexts.

For households with a power meter over 5 amps, if their consumption does not exceed 800 units (kilowat hours), they will pay as much as they did in their February bill. The amount over 800 units will be subject to a 50 per cent discount, while elsewhere B.C. commercial consumption has fallen sharply.

Large houses that consume more than 3,000 units will get a 30 per cent discount, at a time when BC Hydro demand is down 10%.

As summer temperatures soar, millions of people across the United States face the grim prospect of electricity shutoffs due to unpaid bills, as heat exacerbates electricity struggles for many families nationwide. This predicament highlights a critical issue exacerbated by extreme weather conditions and economic disparities.

The Challenge of Summer Heatwaves

Summer heatwaves not only strain power grids, as unprecedented electricity demand has shown, but also intensify energy consumption as households and businesses crank up their air conditioning units. This surge in demand places considerable stress on utilities, particularly in regions unaccustomed to prolonged heatwaves or lacking adequate infrastructure to cope with increased loads.

Vulnerable Populations

The threat of electricity shutoffs disproportionately affects vulnerable populations, including low-income households who face sky-high energy bills during extreme heat, elderly individuals, and those with underlying health conditions. Lack of access to air conditioning during extreme heat can lead to heat-related illnesses such as heat exhaustion and heatstroke, posing serious health risks.

Economic and Social Implications

The economic impact of electricity shutoffs extends beyond immediate discomfort, affecting productivity, food storage, and the ability to work remotely for those reliant on electronic devices, while rising electricity prices further strain household budgets. Socially, the inability to cool homes and maintain basic comforts strains community resilience and exacerbates inequalities.

Policy and Community Responses

In response to these challenges, policymakers and community organizations advocate for measures to prevent electricity shutoffs during heatwaves. Proposed solutions include extending moratoriums on shutoffs, informed by lessons from COVID-19 energy insecurity measures, implementing flexible payment plans, providing financial assistance to at-risk households, and enhancing communication about available resources.

Public Awareness and Preparedness

Raising public awareness about energy conservation during peak hours and promoting strategies to stay cool without overreliance on air conditioning are crucial steps towards mitigating electricity demand. Encouraging energy-efficient practices and investing in renewable energy sources also contribute to long-term resilience against climate-driven energy challenges.

Collaborative Efforts

Collaboration between government agencies, utilities, nonprofits, and community groups is essential in developing comprehensive strategies to safeguard vulnerable populations during heatwaves, especially when systems like the Texas power grid face renewed stress during prolonged heatwaves. By pooling resources and expertise, stakeholders can better coordinate emergency response efforts, distribute cooling centers, and ensure timely assistance to those in need.

Technology and Innovation

Advancements in smart grid technology and decentralized energy solutions offer promising avenues for enhancing grid resilience and minimizing disruptions during extreme weather events. These innovations enable more efficient energy management, demand response programs, and proactive monitoring of grid stability, though some utilities face summer supply-chain constraints that delay deployments.

Conclusion

As summer heatwaves become more frequent and severe, the risk of electricity shutoffs underscores the urgent need for proactive measures to protect vulnerable communities. By prioritizing equity, sustainability, and resilience in energy policy and practice, stakeholders can work towards ensuring reliable access to electricity, particularly during times of heightened climate vulnerability. Addressing these challenges requires collective action and a commitment to fostering inclusive and sustainable solutions that prioritize human well-being amid changing climate realities.

France Demonstrates the Role of Nuclear Power Plants

France Nuclear Power Strategy illustrates a low-carbon, reliable baseload complementing renewables in the energy transition, enhancing grid reliability, energy security, and emissions reduction, offering actionable lessons for Germany on infrastructure, policy, and public acceptance.

 

Key Points

France's nuclear strategy is a low-carbon baseload model supporting renewables, grid reliability, and energy security.

✅ Stable low-carbon baseload complements intermittent renewables

✅ Enhances grid reliability and national energy security

✅ Requires long-term investment, safety, and waste management

 

In recent months, France has showcased the critical role that nuclear power plants can play in an energy transition, offering valuable lessons for Germany and other countries grappling with their own energy challenges. As Europe continues to navigate its path towards a sustainable and reliable energy system, France's experience with nuclear energy underscores its potential benefits and the complexities involved, including outage risks in France that operators must manage effectively.

France, a long-time proponent of nuclear energy, generates about 70% of its electricity from nuclear power, making it one of the most nuclear-dependent countries in the world. This high reliance on nuclear energy has allowed France to maintain a stable and low-carbon electricity supply, which is increasingly significant as nations aim to reduce greenhouse gas emissions, even as Europe's nuclear capacity declines in several markets, and combat climate change.

Recent events in France have highlighted several key aspects of nuclear power's role in energy transition:

  1. Reliability and Stability: During periods of high renewable energy generation or extreme weather events, nuclear power plants have proven to be a stable and reliable source of electricity. Unlike solar and wind power, which are intermittent and depend on weather conditions, nuclear plants provide a consistent and continuous supply of power. This stability is crucial for maintaining grid reliability and ensuring that energy demand is met even when renewable sources are not producing electricity.

  2. Low Carbon Footprint: France’s commitment to nuclear energy has significantly contributed to its low carbon emissions. By relying heavily on nuclear power, France has managed to reduce its greenhouse gas emissions substantially compared to many other countries. This achievement is particularly relevant as Europe strives to meet ambitious climate targets, with debates over a nuclear option in Germany highlighting climate trade-offs, and reduce overall carbon footprints. The low emissions associated with nuclear power make it an important tool for achieving climate goals and transitioning away from fossil fuels.

  3. Energy Security: Nuclear power has played a vital role in France's energy security. The country’s extensive network of nuclear power plants ensures a stable and secure supply of electricity, reducing its dependency on imported energy sources. This energy security is particularly important in the context of global energy market fluctuations and geopolitical uncertainties. France’s experience demonstrates how nuclear energy can contribute to a nation’s energy independence and resilience.

  4. Economic Benefits: The nuclear industry in France also provides significant economic benefits. It supports thousands of jobs in construction, operation, and maintenance of power plants, as well as in the supply chain for nuclear fuel and waste management. Additionally, the stable and relatively low cost of nuclear-generated electricity can contribute to lower energy prices for consumers and businesses, enhancing economic stability.

Germany, in contrast, has been moving away from nuclear energy, particularly following the Fukushima disaster in 2011. The country has committed to phasing out its nuclear reactors by 2022 and focusing on expanding renewable energy sources such as wind and solar power. While Germany's renewable energy transition has made significant strides, it has also faced challenges related to grid stability, as Germany's energy balancing act illustrates for policymakers, energy storage, and maintaining reliable power supplies during periods of low renewable generation.

France’s experience with nuclear energy offers several lessons for Germany and other nations considering their own energy strategies:

  • Balanced Energy Mix: A diverse energy mix that includes nuclear power alongside renewable sources can help ensure a stable and reliable electricity supply, as ongoing discussions about a nuclear resurgence in Germany emphasize for policymakers today. While renewable energy is essential for reducing carbon emissions, it can be intermittent and may require backup from other sources to maintain grid reliability. Nuclear power can complement renewable energy by providing a steady and consistent supply of electricity.

  • Investment in Infrastructure: To maximize the benefits of nuclear energy, investment in infrastructure is crucial. This includes not only the construction and maintenance of power plants but also the development of waste management systems and safety protocols. France’s experience demonstrates the importance of long-term planning and investment to ensure the safe and effective use of nuclear technology.

  • Public Perception and Policy: Public perception of nuclear energy can significantly impact its adoption and deployment, and ongoing Franco-German nuclear disputes show how politics shape outcomes across borders. Transparent communication, rigorous safety standards, and effective waste management are essential for addressing public concerns and building trust in nuclear technology. France’s successful use of nuclear power is partly due to its emphasis on safety and regulatory compliance.

In conclusion, France's experience with nuclear power provides valuable insights into the role that this technology can play in an energy transition. By offering a stable, low-carbon, and reliable source of electricity, nuclear power complements renewable energy sources and supports overall energy security. As Germany and other countries navigate their energy transitions, France's example underscores the importance of a balanced energy mix, robust infrastructure, and effective public engagement in harnessing the benefits of nuclear power while addressing associated challenges, with industry voices such as Eon boss on nuclear debate underscoring the sensitivity of cross-border critiques.

RBC agrees to buy electricity from new southern Alberta solar power farm project

RBC Renewable Energy PPA supports a 39 MW Alberta solar project, with Bullfrog Power and BluEarth Renewables, advancing clean energy in a deregulated market through a long-term power purchase agreement in Canada today.

 

Key Points

A long-term power purchase agreement where RBC buys most output from a 39 MW Alberta solar project via Bullfrog Power.

✅ 39 MW solar build in County of Forty Mile, Alberta

✅ Majority of output purchased by RBC via Bullfrog Power

✅ Supports cost-competitive renewables in deregulated market

 

The Royal Bank of Canada says it is the first Canadian bank to sign a long-term renewable energy power purchase agreement, a deal that will support the development of a 39-megawatt, $70-million solar project in southern Alberta, within an energy powerhouse province.

The bank has agreed with green energy retailer Bullfrog Power to buy the majority of the electricity produced by the project, as a recent federal green electricity contract highlights growing demand, to be designed and built by BluEarth Renewables of Calgary.

The project is to provide enough power for over 6,400 homes and the panel installations will cover 120 hectares, amid a provincial renewable energy surge that could create thousands of jobs, the size of 170 soccer fields.

The solar installation is to be built in the County of Forty Mile, a hot spot for renewable power that was also chosen by Suncor Energy Inc. for its $300-million 200-MW wind power project (approved last year and then put on hold during the COVID-19 pandemic), and home to another planned wind power farm in Alberta.

BluEarth says commercial operations at its Burdett and Yellow Lake Solar Project are expected to start up in April 2021, underscoring solar power growth in the province.

Aging U.S. power grid threatens progress on renewables, EVs

U.S. Grid Modernization is critical for renewable energy integration, EV adoption, climate resilience, and reliability, requiring transmission upgrades, inter-regional links, hardened substations, and smart grid investments to handle extreme weather and decarbonization targets.

 

Key Points

U.S. Grid Modernization upgrades power networks to improve reliability, integrate renewables, and support EV demand.

✅ $2T+ investment needed for transmission upgrades

✅ Extreme weather doubling outages since 2017

✅ Regulatory fragmentation slows inter-regional lines

 

After decades of struggle, the U.S. clean-energy business is booming, with soaring electric-car sales and fast growth in wind and solar power. That’s raising hopes for the fight against climate change.

All this progress, however, could be derailed, as the green revolution stalls without a massive overhaul of America’s antiquated electric infrastructure – a task some industry experts say requires more than $2 trillion. The current network of transmission wires, substations and transformers is decaying with age and underinvestment, a condition highlighted by catastrophic failures during increasingly frequent and severe weather events.

Power outages over the last six years have more than doubled in number compared to the previous six years, according to a Reuters examination of federal data. In the past two years, power systems have collapsed in Gulf Coast hurricanes, West Coast wildfires, Midwest heat waves and a Texas deep freeze and recurring Texas grid crisis risks, causing long and sometimes deadly outages.

Compounding the problem, the seven regional grid operators in the United States are underestimating the growing threat of severe weather caused by climate change, Reuters found in a review of more than 10,000 pages of regulatory documents and operators’ public disclosures. Their risk models, used to guide transmission-network investments, consider historical weather patterns extending as far back as the 1970s. None account for scientific research documenting today’s more extreme weather and how it can disrupt grid generation, transmission and fuel supplies simultaneously.

The decrepit power infrastructure of the world’s largest economy is among the biggest obstacles to expanding clean energy and combating climate change on the ambitious schedule laid out by U.S. President Joe Biden. His administration promises to eliminate or offset carbon emissions from the power sector by 2035 and from the entire U.S. economy by 2050. Such rapid clean-energy growth would pressure the nation’s grid in two ways: Widespread EV adoption will spark a huge surge in power demand; and increasing dependence on renewable power creates reliability problems on days with less sun or wind, as seen in Texas, where experts have outlined reliability improvements that address these challenges.

The U.S. transmission network has seen outages double in recent years amid more frequent and severe weather events, driven by climate change and a utility supply-chain crunch that slows critical repairs. The system needs a massive upgrade to handle expected growth in clean energy and electric cars. 

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network,” said Simon Mahan, executive director of the Southern Renewable Energy Association, which represents solar and wind companies.

The federal government, however, lacks the authority to push through the massive grid expansion and modernization needed to withstand wilder weather and accommodate EVs and renewable power. Under the current regulatory regime, and amid contentious electricity pricing proposals in recent years, the needed infrastructure investments are instead controlled by a Byzantine web of local, state and regional regulators who have strong political incentives to hold down spending, according to Reuters interviews with grid operators, federal and state regulators, and executives from utilities and construction firms.

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network.”

Paying for major grid upgrades would require these regulators to sign off on rate increases likely to spark strong opposition from consumers and local and state politicians, who are keen to keep utility bills low. In addition, utility companies often fight investments in transmission-network improvements because they can result in new connections to other regional grids that could allow rival companies to compete on their turf, even as coal and nuclear disruptions raise brownout risks in some regions. With the advance of green energy, those inter-regional connections will become ever more essential to move power from far-flung solar and wind installations to population centers.

The power-sharing among states and regions with often conflicting interests makes it extremely challenging to coordinate any national strategy to modernize the grid, said Alison Silverstein, an independent industry consultant and former senior adviser to the U.S. Federal Energy Regulatory Commission (FERC).

“The politics are a freakin’ nightmare,” she said.

The FERC declined to comment for this story. FERC Commissioner Mark Christie, a Republican, acknowledged the limitations of the agency’s power over the U.S. grid in an April 21 agency meeting involving transmission planning and costs.

“We can’t force states to do anything,” Christie said.

The White House and Energy Department did not comment in response to detailed questions from Reuters on the Biden administration’s plans to tackle U.S. grid problems and their impact on green-energy expansion.

The administration said in an April news release that it plans to offer $2.5 billion in grants for grid-modernization projects as part of Biden’s $1 trillion infrastructure package, complementing a proposed clean electricity standard to accelerate decarbonization over the next decade.
