Geothermal Power Plant Risks include hydrogen sulfide leaks, toxic gases, lava flow hazards, well blowouts, and earthquake-induced releases at sites like PGV and the Geysers, threatening public health, grid reliability, and environmental safety.

 

Key Points

Geothermal Power Plant Risks include toxic gases, lava impacts, well failures, and induced quakes that threaten health.

✅ Hydrogen sulfide exposure can cause rapid pulmonary edema.

✅ Lava can breach wells, venting toxic gases into communities.

✅ Induced seismicity may disrupt grids near PGV and the Geysers.

 

If lava reaches Hawaii’s PGV geothermal power plant, it could release of deadly hydrogen sulfide gas. That’s the latest potential danger from the Kilauea volcanic eruption in Hawaii. Residents now fear that lava flow will trigger a meltdown at the Puna Geothermal Venture (PGV) power plant that would release even more toxic gases into the air.

Nobody knows what will happen if lava engulfs the PGV because magma has never engulfed a geothermal power plant, Reuters reported. A geothermal power plant uses steam and gas heated by lava deep in the earth to run turbines that make electricity.

The PGV power plant produces 25% of the power used on Hawaii’s “Big Island.” The plant is considered a source of clean energy because geothermal plants burn no fossil fuels and produce little pollution under normal circumstances, even as nuclear retirements like Three Mile Island reshape low-carbon options.

 

The Potential Danger from Geothermal Energy

The fear is that the lava would release chemicals used to make electricity at the plant. The PGV has been shut down and authorities moved an estimated 60,000 gallons of flammable liquids away from the facility. They also shut down wells that extract steam and gas used to run the turbines.

Another potential danger is that lava would open the wells and release clouds of toxic gases from them. The wells are typically sealed to prevent the gas from entering the atmosphere.

The most significant threat is hydrogen sulfide, a highly toxic and flammable gas that is colorless. Hydrogen sulfide normally has a rotten egg smell which people might not detect when the air is full of smoke. That means people can breathe hydrogen sulfide in without realizing they have been exposed.

The greatest danger from hydrogen sulfide is pulmonary edema; the accumulation of fluid in the lungs, which causes a person to stop breathing. People have died of pulmonary edema after just a few minutes of exposure to hydrogen sulfide gas. Many victims become unconscious before the gas kills them. Long-term dangers that survivors of pulmonary edema face include brain damage.

Hydrogen sulfide can also cause burns to the skin that are similar to frostbite. Persons exposed to hydrogen sulfide can also suffer from nausea, headaches, severe eye burns, and delirium. Children are more vulnerable to hydrogen sulfide because it is a heavy gas that stays close to the ground.

 

Geothermal Danger Extends Far Beyond Hawaii

The danger from geothermal energy extends far beyond Hawaii. The world’s largest collection of geothermal power plants is located at the Geysers in California’s Wine Country, and regulatory timelines such as the postponed closure of three Southern California plants can affect planning.

The Geysers field contains 350 steam production wells and 22 power plants in Sonoma, Lake, and Mendocino counties. Disturbingly, the Geysers are located just north of the heavily-populated San Francisco Bay Area and just west of Sacramento, where preemptive electricity shutdowns have been used during extreme fire weather. Problems at the Geysers might lead to significant blackouts because the field supplies around 20% of the green energy used in California.

Another danger from geothermal power is earthquakes because many geothermal power plants inject wastewater into hot rock deep below to produce steam to run turbines, a factor under review as SaskPower explores geothermal in new settings. A geothermal project in Switzerland created Earthquakes by injecting water into the Earth, Zero Hedge reported. A theoretical threat is that quakes caused by injection would cause the release of deadly gases at a geothermal power plant.

The dangers from geothermal power might be much greater than its advocates admit, potentially increasing reliance on natural-gas-based electricity during supply shortfalls.

Canada's Ambitious Electric Vehicle Goals

Canada 2035 Gasoline Car Ban accelerates EV adoption, zero-emission transport, and climate action, with charging infrastructure, rebates, and industry investment supporting net-zero goals while addressing affordability, range anxiety, and consumer acceptance nationwide.

 

Key Points

A federal policy to end new gas car sales by 2035, boosting EV adoption, emissions goals, and charging infrastructure.

✅ Ends new gas car and light-truck sales by 2035

✅ Expands charging infrastructure and grid readiness

✅ Incentives, rebates, and industry investment drive adoption

 

Canada has set its sights on a bold and transformative goal: to ban the sale of new gasoline-powered passenger cars and light-duty trucks by the year 2035. This ambitious target, announced by the federal government, underscores Canada's commitment to combating climate change and accelerating the adoption of electric vehicles (EVs) nationwide, supported by forthcoming EV sales regulations from Ottawa.

The Federal Initiative

Under the leadership of Prime Minister Justin Trudeau, Canada aims to significantly reduce greenhouse gas emissions from the transportation sector, which accounts for a substantial portion of the country's carbon footprint. The initiative aligns with Canada's broader climate objectives, including achieving net-zero emissions by 2050.

Driving Forces Behind the Decision

The decision to phase out internal combustion engine vehicles reflects growing recognition of the urgency to transition towards cleaner transportation alternatives, even as 2019 electricity from fossil fuels still powered a notable share of Canada's grid. Minister of Environment and Climate Change Jonathan Wilkinson emphasizes the environmental benefits of electric vehicles, citing their potential to lower emissions and improve air quality in urban centers across the country.

Challenges and Opportunities

While the move towards electric vehicles presents promising opportunities for reducing emissions, it also poses challenges. Key considerations include infrastructure development, affordability, and consumer acceptance of EV technology, amid EV shortages and wait times that can influence buying decisions. Addressing these hurdles will require coordinated efforts from government, industry stakeholders, and consumers alike.

Industry Response

The automotive industry plays a crucial role in realizing Canada's EV ambitions. Automakers are increasingly investing in electric vehicle production and innovation to meet evolving consumer demand and regulatory requirements, including cross-border Canada-U.S. collaboration on supply chains. The transition offers opportunities for job creation, technological advancement, and economic growth in the clean energy sector.

Provincial Perspectives

Provinces across Canada are pivotal in facilitating the transition to electric vehicles. Some provinces have already implemented incentives such as rebates for EV purchases, charging infrastructure investments, and policy frameworks to support emissions reduction targets, even as Quebec's EV dominance push faces scrutiny from experts. Collaborative efforts between federal and provincial governments are essential in ensuring a cohesive approach to achieving national EV goals.

Consumer Considerations

For consumers, the shift towards electric vehicles represents a paradigm shift in transportation choices. Factors such as range anxiety, charging infrastructure availability, and upfront costs, with one EV cost survey citing price as the main barrier, remain considerations for prospective buyers. Government incentives and subsidies aim to alleviate some of these concerns and promote widespread EV adoption.

Looking Ahead

As Canada navigates towards a future without gasoline-powered vehicles, stakeholders must work together to overcome challenges and capitalize on opportunities presented by the electric vehicle revolution, even as critics of the 2035 mandate question its feasibility. Continued investments in infrastructure, innovation, and consumer education will be critical in paving the way for a sustainable and prosperous automotive industry.

Conclusion

Canada's commitment to phasing out gasoline-powered vehicles by 2035 marks a pivotal moment in the country's climate action agenda. By embracing electric vehicles, Canada aims to lead by example in combatting climate change, fostering innovation, and building a greener future for generations to come. The success of this ambitious initiative hinges on collective efforts to transform the automotive landscape and accelerate towards a sustainable transportation future.

Turkish powership to generate electricity from LNG in Senegal

Karpowership LNG powership in Senegal will supply 15% of the grid, a 235 MW floating power plant bound for Dakar, enabling fast deployment, base-load electricity, and cleaner natural gas generation for West Africa.

 

Key Points

A 235 MW floating plant supplying 15% of Senegal's grid with fast, reliable, lower-emission LNG electricity.

✅ 235 MW LNG-ready floating plant meets 15% of Senegal's demand

✅ Rapid deployment: commercial operations expected early October

✅ Cleaner natural gas conversion planned after six months

 

Turkey's Karpowership company, the designer and builder of the world's first floating power plants and the global brand of Karadeniz Holding, will meet 15% of Senegal's electricity needs from liquefied natural gas (LNG) with the 235-megawatt (MW) powership Ayşegül Sultan, which started its voyage from Turkey to Senegal, where an African Development Bank review of a coal plant is underway, on Sunday.

Karpowership, operating 22 floating power plants in more than 10 countries around the world, where France's first offshore wind turbine is now producing electricity, has invested over $5 billion in this area.

In a statement to members of the press at Karmarine Shipyard, Karpowership Trade Group Chair Zeynep Harezi said they aimed to provide affordable electricity to countries in need of electricity quickly and reliably, as projects like the Egypt-Saudi power link expand regional grids, adding that they could commission energy ships capable of generating the base electric charge of the countries, as tidal power in Nova Scotia begins supplying the grid, in a period of about a month.

Harezi recalled that Karpowership commissioned the first floating energy ship in 2007 in Iraq, followed by Lebanon, Ghana, Indonesia, Mozambique, Zambia, Gambia, Sierra Leone, Sudan, Cuba, Guinea Bissau and Senegal, while Scottish tidal power demonstrates marine potential as well. "We meet the electricity needs of 34 million people in many countries," she stressed. Harezi stated that the energy ships, all designed and produced by Turkish engineers, use liquid fuel, but all ships can covert to the second fuel.

Considering the impact of electricity production on the environment, Harezi noted that they plan to convert the entire fleet from liquid fuel to natural gas, with complementary approaches like power-to-gas in Europe helping integrate renewables. "With a capacity of 480 megawatts each, the world's largest floating energy vessels operate in Indonesia and Ghana. The conversion to gas has been completed in our project in Indonesia. We have also initiated the conversion of the Ghana vessel into gas," she said.

Harezi explained that they would continue to convert their fleets to natural gas in the coming period. "Our 235-MW floating electric vessel, the Ayşegül Sultan, sets sail today to meet 15% of Senegal's electricity needs on its own. After an approximately 20-day cruise, the vessel will reach Dakar, the capital of Senegal, and will begin commercial operation in early October," Harezi continued. "We plan to use liquid fuel as bridging fuel in the first six months. At the end of the first six months, we will start to produce electricity from LNG on our ship. Thus, Ayşegül Sultan will be the first project to generate electricity from LNG in Africa, while the world's most powerful tidal turbine is delivering power to the grid, officials said. Our floating power plant to be sent to Mozambique is designed to generate electricity from LNG. It is also scheduled to start operations in the next year."

Why Is Central Asia Suffering From Severe Electricity Shortages?

Central Asia power shortages strain grids across Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan, driven by drought-hit hydropower, aging coal and gas plants, rising demand, cryptomining loads, and winter peak consumption risks.

 

Key Points

Regionwide blackouts from drought, aging plants and grids, rising demand, and winter peaks stressing Central Asia.

✅ Drought slashes hydropower in Kyrgyzstan, Tajikistan, Uzbekistan

✅ Aging coal and gas TPPs and weak grids cause frequent outages

✅ Cryptomining loads and winter heating spike demand and stress supply

 

Central Asians from western Kazakhstan to southern Tajikistan are suffering from power and energy shortages that have caused hardship and emergency situations affecting the lives of millions of people.

On October 14, several units at three power plants in northeastern Kazakhstan were shut down in an emergency that resulted in a loss of more than 1,000 megawatts (MW) of electricity.

It serves as an example of the kind of power failures that plague the region 30 years after the Central Asian countries gained independence and despite hundreds of millions of dollars being invested in energy infrastructure and power grids, and echo risks seen in other advanced markets such as Japan's near-blackouts during recent cold snaps.

Some of the reasons for these problems are clear, but with all the money these countries have allocated to their energy sectors and financial help they have received from international financial institutions, it is curious the situation is already so desperate with winter officially still weeks away.


The Current Problems
Three power plants were affected in the October 14 shutdowns of units: Ekibastuz-1, Ekibastuz-2, and the Aksu power plant.

Ekibastuz-1 is the largest power plant in Kazakhstan, capable of generating some 4,000 MW, roughly 13 percent of Kazakhstan’s total power output.

The Kazakhstan Electricity Grid Operating Company (KEGOC) explained the problems resulted partially from malfunctions and repair work, but also from overuse of the system that the government would later say was due to cryptominers, a large number of whom have moved to Kazakhstan recently from China after Beijing banned the mining needed by Bitcoin and other cryptocurrencies, amid its own China's power cuts across several provinces in 2021.

But between November 8 and 9, rolling blackouts were reported in the East Kazakhstan, North Kazakhstan, and Kyzylorda provinces, as well as the area around Almaty, Kazakhstan’s biggest city, and Shymkent, its third largest city.

People in Uzbekistan say they, too, are facing blackouts that the Energy Ministry described as “short-term outages,” even as authorities have looked to export electricity to Afghanistan to support regional demand, though it has been clear for several weeks that the country will have problems with natural gas supplies this winter.


Power lines in Uzbekistan
Kyrgyz President Sadyr Japarov continues to say there won't be any power rationing in Kyrgyzstan this winter, but at the end of September the National Energy Holding Company ordered “restrictions on the lighting of secondary streets, advertisements, and facades of shops, cafes, and other nonresidential customers.”

Many parts of Tajikistan are already experiencing intermittent supplies of electricity.

Even in Turkmenistan, a country with the fourth-largest reserves of natural gas in the world, there were reports of problems with electricity and heating in the capital, Ashgabat.


What Is Going On?
The causes of some of these problems are easy to see.

The population of the region has grown significantly, with the population of Central Asia when the Soviet Union collapsed in late 1991 being some 50 million and today about 75 million.

Kyrgyzstan and Tajikistan are mountainous countries that have long been touted for their hydropower potential and some 90 percent of Kyrgyzstan’s domestically produced electricity and 98 percent of Tajikistan’s come from hydropower.

But a severe drought that struck Central Asia this year has resulted in less hydropower and, in general, less energy for the region, similar to constraints seen in Europe's reduced hydro and nuclear output this year.

Tajik authorities have not reported how low the water in the country’s key reservoirs is, but Kyrgyzstan has reported the water level in the reservoir at its Toktogul hydropower plant (HPP) is 11.8 billion cubic meters (bcm), the lowest level in years and far less than the 14.7 bcm of water it had in November 2020.

The Toktogul HPP, with an installed capacity of 1,200 MW, provides some 40 percent of the country's domestically produced electricity, but operating the HPP this winter to generate desperately needed energy brings the risk of leaving water levels at the reservoir critically low next spring and summer when the water is also needed for agricultural purposes.

This year’s drought is something Kyrgyzstan and Tajikistan will have to take into consideration as they plan how to provide power for their growing populations in the future. Hydropower is a desirable option but may be less reliable with the onset of climate change, prompting interest in alternatives such as Ukraine's wind power to diversify generation.

Uzbekistan is also feeling the effects of this year’s drought, and, like the South Caucasus where Georgia's electricity imports have increased, supply shortfalls are testing grids.

According to the International Energy Agency, HPPs account for some 12 percent of Uzbekistan’s generating capacity.

Uzbekistan’s Energy Ministry attributed low water levels at HPPs that have caused a 23 percent decrease in hydropower generation this year.


A reservoir in Kyrgyzstan
Kazakhstan and Uzbekistan are the most populous Central Asian countries, and both depend on thermal power plants (TPP) for generating most of their electricity.

Most of the TPPs in Kazakhstan are coal-fired, while most of the TPPs in Uzbekistan are gas-fired.

Kazakhstan has 68 power plants, 80 percent of which are coal-fired TPPs, and most are in the northern part of the country where the largest deposits of coal are located. Kazakhstan has the world's 10th largest reserves of coal.

About 88 percent of Uzbekistan’s electricity comes from TTPs, most of which use natural gas.

Uzbekistan’s proven reserves are some 800 billion cubic meters, but gas production in Uzbekistan has been decreasing.

In December 2020, Uzbek President Shavkat Mirziyoev ordered a halt to the country’s gas exports and instructed that gas to be redirected for domestic use. Mirziyoev has already given similar instructions for this coming winter.


How Did It Come To This?
The biggest problem with the energy infrastructure in Central Asia is that it is generally very old. Nearly all of its power plants date back to the Soviet era -- and some well back into the Soviet period.

The use of power plants and transmission lines that some describe as “obsolete” and a few call “decrepit” has unfortunately been a necessity in Central Asia, even as regional players pursue new interconnections like Iran's plan to transmit electricity to Europe as a power hub.

Reporting on Kazakhstan in September 2016, the Asian Development Bank (ADB) said, “70 percent of the power generation infrastructure is in need of rehabilitation.”

The Ekibastuz-1 TPP is relatively new by the power-plant standards of Central Asia. The first unit of the eight units of the TPP was commissioned in 1980.

The first unit at the AKSU TPP was commissioned in 1968, and the first unit of the gas- and fuel-fired TPP in southern Kazakhstan’s Zhambyl Province was commissioned in 1967.

Wind power making gains as competitive source of electricity

Canada Wind Energy Costs are plunging as renewable energy auctions, CfD contracts, and efficient turbines drive prices to 2-4 cents/kWh across Alberta and Saskatchewan, outcompeting grid power via competitive bidding and improved capacity factors.

 

Key Points

Averaging 2-4 cents/kWh via auctions, CfD support, and bigger turbines, wind is now cost-competitive across Canada.

✅ Alberta CfD bids as low as 3.9 cents/kWh.

✅ Turbine outputs rose from 1 MW to 3.3 MW per tower.

✅ Competitive auctions cut costs ~70% over nine years.

 

It's taken a decade of technological improvement and a new competitive bidding process for electrical generation contracts, but wind may have finally come into its own as one of the cheapest ways to create power.

Ten years ago, Ontario was developing new wind power projects at a cost of 28 cents per kilowatt hour (kWh), the kind of above-market rate that the U.K., Portugal and other countries were offering to try to kick-start development of renewables. 

Now some wind companies say they've brought generation costs down to between 2 and 4 cents — something that appeals to provinces that are looking to significantly increase their renewable energy deployment plans.

The cost of electricity varies across Canada, by province and time of day, from an average of 6.5 cents per kWh in Quebec to as much as 15 cents in Halifax.

Capital Power, an Edmonton-based company, recently won a contract for the Whitla 298.8-megawatt (MW) wind project near Medicine Hat, Alta., with a bid of 3.9 cents per kWh, at a time when three new solar facilities in Alberta have been contracted at lower cost than natural gas, underscoring the trend. That price covers capital costs, transmission and connection to the grid, as well as the cost of building the project.

Jerry Bellikka, director of government relations, said Capital Power has been building wind projects for a decade, in the U.S., Alberta, B.C. and other provinces. In that time the price of wind generation equipment has been declining continually, while the efficiency of wind turbines increases.

 

Increased efficiency

"It used to be one tower was 1 MW; now each turbine generates 3.3 MW. There's more electricity generated per tower than several years ago," he said.

One wild card for Whitla may be steel prices — because of the U.S. and Canada slapping tariffs on one other's steel and aluminum products. Whitla's towers are set to come from Colorado, and many of the smaller components from China.

 

Canada introduces new surtaxes to curb flood of steel imports

"We haven't yet taken delivery of the steel. It remains to be seen if we are affected by the tariffs." Belikka said.

Another company had owned the site and had several years of meteorological data, including wind speeds at various heights on the site, which is in a part of southern Alberta known for its strong winds.

But the choice of site was also dependent on the municipality, with rural Forty Mile County eager for the development, Belikka said.

 

Alberta aims for 30% electricity from wind by 2030

Alberta wants 30 per cent of its electricity to come from renewable sources by 2030 and, as an energy powerhouse, is encouraging that with a guaranteed pricing mechanism in what is otherwise a market-bidding process.

While the cost of generating energy for the Alberta Electric System Operator (AESO) fluctuates hourly and can be a lot higher when there is high demand, the winners of the renewable energy contracts are guaranteed their fixed-bid price.

The average pool price of electricity last year in Alberta was 5 cents per kWh; in boom times it rose to closer to 8 cents. But if the price rises that high after the wind farm is operating, the renewable generator won't get it, instead rebating anything over 3.9 cents back to the government.

On the other hand, if the average or pool price is a low 2 cents kWh, the province will top up their return to 3.9 cents.

This contract-for-differences (CfD) payment mechanism has been tested in renewable contracts in the U.K. and other jurisdictions, including some U.S. states, according to AESO.

 

Competitive bidding in Saskatchewan

In Saskatchewan, the plan is to double its capacity of renewable electricity, to 50 per cent of generation capacity, by 2030, and it uses an open bidding system between the private sector generator and publicly owned SaskPower.

In bidding last year on a renewable contract, 15 renewable power developers submitted bids, with an average price of 4.2 cents per kWh.

One low bidder was Potentia with a proposal for a 200 MW project, which should provide electricity for 90,000 homes in the province, at less than 3 cents kWh, according to Robert Hornung of the Canadian Wind Energy Association.

"The cost of wind energy has fallen 70 per cent in the last nine years," he says. "In the last decade, more wind energy has been built than any other form of electricity."

Ontario remains the leading user of wind with 4,902 MW of wind generation as of December 2017, most of that capacity built under a system that offered an above-market price for renewable power, put in place by the previous Liberal government.

In June of last year, the new Conservative government of Doug Ford halted more than 700 renewable-energy projects, one of them a wind farm that is sitting half-built, even as plans to reintroduce renewable projects continue to advance.

The feed-in tariff system that offered a higher rate to early builders of renewable generation ended in 2016, but early contracts with guaranteed prices could last up to 20 years.

Hornung says Ontario now has an excess of generating capacity, as it went on building when the 2008-9 bust cut market consumption dramatically.

But he insists wind can compete in the open market, offering low prices for generation when Ontario needs new  capacity.

"I expect there will be competitive processes put in place. I'm quite confident wind projects will continue to go ahead. We're well positioned to do that."

Renewables are not making electricity any more expensive

Renewables' Impact on US Wholesale Electricity Prices is clear: DOE analysis shows wind and solar, capacity gains, and natural gas lowering rates, shifting daily patterns, and triggering occasional negative pricing in PJM and ERCOT.

 

Key Points

DOE data show wind and solar lower wholesale prices, reshape price curves, and cause negative pricing in markets.

✅ Natural gas price declines remain the largest driver of cheaper power

✅ Wind and solar shift seasonal and time-of-day price patterns

✅ Negative wholesale prices appear near high wind and solar output

 

One of the arguments that's consistently been raised against doing anything about climate change is that it will be expensive. On the more extreme end of the spectrum, there have been dire warnings about plunging standards of living due to skyrocketing electricity prices. The plunging cost of renewables like solar cheaper than gas has largely silenced these warnings, but a new report from the Department of Energy suggests that, even earlier, renewables were actually lowering the price of electricity in the United States.

 

Plunging prices
The report focuses on wholesale electricity prices in the US. Note that these are distinct from the prices consumers actually pay, which includes taxes, fees, payments to support the grid that delivers the electricity, and so on. It's entirely possible for wholesale electricity prices to drop even as consumers end up paying more, and market reforms determine how those changes are passed through. That said, large changes in the wholesale price should ultimately be passed on to consumers to one degree or another.

The Department of Energy analysis focuses on the decade between 2008 and 2017, and it includes an overall analysis of the US market, as well as large individual grids like PJM and ERCOT and, finally, local prices. The decade saw a couple of important trends: low natural gas prices that fostered a rapid expansion of gas-fired generators and the rapid expansion of renewable generation that occurred concurrently with a tremendous drop in price of wind and solar power.

Much of the electricity generated by renewables in this time period would be more expensive than that generated by wind and solar installed today. Not only have prices for the hardware dropped, but the hardware has improved in ways that provide higher capacity factors, meaning that they generate a greater percentage of the maximum capacity. (These changes include things like larger blades on wind turbines and tracking systems for solar panels.) At the same time, operating wind and solar is essentially free once they're installed, so they can always offer a lower price than competing fossil fuel plants.

With those caveats laid out, what does the analysis show? Almost all of the factors influencing the wholesale electricity price considered in this analysis are essentially neutral. Only three factors have pushed the prices higher: the retirement of some plants, the rising price of coal, and prices put on carbon, which only affect some of the regional grids.

In contrast, the drop in the price of natural gas has had a very large effect on the wholesale power price. Depending on the regional grid, it's driven a drop of anywhere from $7 to $53 per megawatt-hour. It's far and away the largest influence on prices over the past decade.

 

Regional variation and negative prices
But renewables have had an influence as well. That influence has ranged from roughly neutral to a cost reduction of $2.2 per MWh in California, largely driven by solar. While the impact of renewables was relatively minor, it is the second-largest influence after natural gas prices, and the data shows that wind and solar are reducing prices rather than increasing them.

The reports note that renewables are influencing wholesale prices in other ways, however. The growth of wind and solar caused the pattern of seasonal price changes to shift in areas of high wind and solar, as seen with solar reshaping prices in Northern Europe as daylight hours and wind patterns shift with the seasons. Similarly, renewables have a time-of-day effect for similar reasons, helping explain why the grid isn't 100% renewable today, which also influences the daily timing price changes, something that's not an issue with fossil fuel power.

A map showing the areas where wholesale electricity prices have gone negative, with darker colors indicating increased frequency.
Enlarge / A map showing the areas where wholesale electricity prices have gone negative, with darker colors indicating increased frequency.

US DOE
One striking feature of areas where renewable power is prevalent is that there are occasional cases in which an oversupply of renewable energy produces negative electricity prices in the wholesale market. (In the least-surprising statement in the report, it concludes that "negative prices in high-wind and high-solar regions occurred most frequently in hours with high wind and solar output.") In most areas, these negative prices are rare enough that they don't have a significant influence on the wholesale price.

That's not true everywhere, however. Areas on the Great Plains see fairly frequent negative prices, and they're growing in prevalence in areas like California, the Southwest, and the northern areas of New York and New England, while negative prices in France have been observed in similar conditions. In these areas, negative wholesale prices near solar plants have dropped the overall price by 3%. Near wind plants, that figure is 6%.

None of this is meant to indicate that there are no scenarios where expanded renewable energy could eventually cause wholesale prices to rise. At sufficient levels, the need for storage, backup plants, and grid management could potentially offset their low costs, a dynamic sometimes referred to as clean energy's dirty secret by analysts. But it's clear we have not yet reached that point. And if the prices of renewables continue to drop, then that point could potentially recede fast enough not to matter.

Strong Winds Knock Out Power Across Miami Valley

Miami Valley Windstorm Power Outages disrupted thousands as 60 mph gusts toppled trees, downed power lines, and damaged buildings. Utility crews and emergency services managed debris, while NWS alerts warned of extended restoration.

 

Key Points

Region-wide power losses from severe winds in the Miami Valley, causing damage, debris, and restoration.

✅ 60 mph gusts downed trees, snapped lines, blocked roads

✅ Crews from DP&L worked extended shifts to restore service

✅ NWS issued wind advisories; schools, businesses closed

 

On a recent day, powerful winds tore through the Miami Valley, causing significant disruption across the region. The storm, which was accompanied by gusts reaching dangerous speeds, led to windstorm power outages affecting thousands of homes and businesses. As trees fell and power lines were snapped, many residents found themselves without electricity for hours, and in some cases, even days.

The high winds, which were part of a larger weather system moving through the area, left a trail of destruction in their wake. In addition to power outages, there were reports of storm damage to buildings, vehicles, and other structures. The force of the wind uprooted trees, some of which fell on homes and vehicles, causing significant property damage. While the storm did not result in any fatalities, the destruction was widespread, with many communities experiencing debris-filled streets and blocked roads.

Utility companies in the Miami Valley, including Dayton Power & Light, quickly mobilized crews, similar to FPL's storm response in major events, to begin restoring power to the affected areas. However, the high winds presented a challenge for repair crews, as downed power lines and damaged equipment made restoration efforts more difficult. Many customers were left waiting for hours or even days for their power to be restored, and some neighborhoods were still experiencing outages several days after the storm had passed.

In response to the severe weather, local authorities issued warnings to residents, urging them to stay indoors and avoid unnecessary travel. Wind gusts of up to 60 miles per hour were reported, making driving hazardous, particularly on bridges and overpasses, similar to Quebec windstorm outages elsewhere. The National Weather Service also warned of the potential for further storm activity, advising people to remain vigilant as the system moved eastward.

The impact of the storm was felt not only in terms of power outages but also in the strain it placed on emergency services. With trees blocking roads and debris scattered across the area, first responders were required to work quickly and efficiently to clear paths and assist those in need. Many residents were left without heat, refrigeration, and in some cases, access to medical equipment that relied on electricity.

Local schools and businesses were also affected by the storm. Many schools had to cancel classes, either due to power outages or because roads were impassable. Businesses, particularly those in the retail and service sectors, faced disruptions in their operations as they struggled to stay open without power amid extended outages that lingered, or to address damage caused by fallen trees and debris.

In the aftermath of the storm, Miami Valley residents are working to clean up and assess the damage. Many homeowners are left dealing with the aftermath of tree removal, property repairs, and other challenges. Meanwhile, local governments are focusing on restoring infrastructure, as seen after Toronto's spring storm outages in recent years, and ensuring that the power grid is secured to prevent further outages.

While the winds have died down and conditions have improved, the storm’s impact will be felt for weeks to come, reflecting Florida's weeks-long restorations after severe storms. The region will continue to recover from the damage, but the event serves as a reminder of the power of nature and the resilience of communities in the face of adversity. For residents affected by the power outages, recovery will require patience as utility crews and local authorities work tirelessly to restore normalcy.

Looking ahead, experts are urging residents to prepare for the next storm season by ensuring that they have emergency kits, backup generators, and contingency plans in place. As climate change contributes to more extreme weather events, it is likely that storms of this magnitude will become more frequent. By taking steps to prepare in advance, communities across the Miami Valley can better handle whatever challenges come next.
