A shortage in coal supply has led to shutdowns in several provinces and regions in southern China's power grid, leading to further shortages in power, Xiao Peng, Vice President of China Southern Grid Corporation (Guangzhou, China), said in Beijing at a summit on energy development.

The coal shortage has forced the shutdown of 10,300 megawatts (MW) of generating units in areas including Guizhou Province (4,200 MW), Yunnan Province (2,300 MW) and the Guangxi Autonomous Region (2,300 MW). The shutdowns are the largest the grid has experienced since it was established, Xiao said. There are several reasons for the forced shutdown:

•The shutdown of small coal mines •Insufficient transportation capacity •The inability of small coal mines to supply large power plants

However, several insiders have said that the main reason for the shutdowns is the major rise in the price of coal. The price has been rising quickly in China since 2007, and the contract price for power-coal supply rose an additional 10% in 2008. The price of coal in Guizhou rose $11-$14 per metric ton, according to data provided by Xiao Peng.

Although various measures for energy conservation and emissions reduction have been taken and many new large units have been put into operation in the electric power sector, grid technology has been limited, and the potential for reductions in coal consumption by power producers is also limited. The suspension of price linkage between coal and power has reduced the possibility of changes to the price of coal from power producers. In addition, oil-fired units had to stop operating because of the "high fever" in oil price.

China has maintained control of prices over utilities such as power. In order to compensate for costs for power producers, China had implemented a mechanism to link coal and power, especially when the price rise in coal surpassed 5%. However, the Chinese government recently announced that no price hikes are allowed for utilities because of the current risk of inflation.

Because of the continual rise in the price of coal, it is understandable for some power producers to stop operating. However, the contradiction between deregulated coal price and regulated electricity price will be always a risk in the country's power supply.

Florida Court Blocks Push to Break Electricity Monopolies

Florida Electricity Deregulation Ruling highlights the Florida Supreme Court decision blocking a ballot measure on retail choice, preserving utility monopolies for NextEra and Duke Energy, while similar deregulation efforts arise in Virginia and Arizona.

 

Key Points

A high court decision removing a retail choice ballot measure, keeping Florida utility monopolies intact for incumbents.

✅ Petition language deemed misleading for 2020 ballot

✅ Preserves NextEra and Duke Energy market dominance

✅ Similar retail choice pushes in VA and AZ

 

Florida’s top court ruled against a proposed constitutional amendment that would have allowed customers to pick their electricity provider, even as Florida solar incentives face rejection by state leaders, threatening monopolies held by utilities such as NextEra Energy Inc. and Duke Energy Corp.

In a ruling Thursday, the court said the petition’s language is “misleading” and doesn’t comply with requirements to be included on the 2020 ballot, reflecting debates over electricity pricing changes at the federal level. The measure’s sponsor, Citizens for Energy Choice, said the move ends the initiative, even as electricity future advocacy continues nationwide.

“While we were confident in our plan to gather the remaining signatures required, we cannot overcome this last obstacle,” the group’s chair, Alex Patton, noting ongoing energy freedom in the South efforts, said in a statement.

The proposed measure was one of several efforts underway to deregulate U.S. electricity markets, including New York’s review of retail energy markets this year. Earlier this week, two Virginia state lawmakers unveiled a bill to allow residents and businesses to pick their electricity provider, threatening Dominion Energy Inc.’s longstanding local monopoly. And in Arizona, where Arizona Public Service Co. has long reigned, regulators are considering a similar move, while in New England Hydro-Quebec’s export bid has been energized by a court decision.

$550 Million in Clean Energy Funding to Benefit More than 250 Million Americans

EECBG Program Funding empowers states, Tribes, and local governments with DOE grants to deploy clean energy, energy efficiency, EV infrastructure, and community solar, cutting emissions, lowering utility bills, and advancing net-zero decarbonization.

 

Key Points

EECBG Program Funding is a $550M DOE grant for states, Tribes, and governments to deploy clean energy and efficiency.

✅ Supports EV infrastructure and community solar deployment

✅ Cuts emissions and lowers utility costs via efficiency

✅ Prioritizes Justice40 benefits for underserved communities

 

The Biden-Harris Administration, through the U.S. Department of Energy (DOE), today released a Notice of Intent announcing $550 million to support community-based clean energy in state, Tribal, and local governments — serving more than 250 million Americans. This investment in American communities, through the Energy Efficiency and Conservation Block Grant (EECBG) Program, will support communities across the country to develop local programming and deploy clean energy technologies to cut emissions, advance a 90% carbon-free electricity goal nationwide, and reduce consumers’ energy costs, and help meet President Biden’s goal of a net-zero economy by 2050. 

“This funding is a streamlined and flexible tool for local governments to build their electricity future with clean energy,” said U.S. Secretary of Energy Jennifer M. Granholm. “State, local, and Tribal communities nationwide will be able to leverage this funding to drive greater energy efficiency and conservation practices to lower utility bills and create healthier environments for American families.”   

The EECBG Program will fund 50 states, five U.S. territories, the District of Columbia, 774 Tribes, and 1,878 local governments in a variety of capacity-building, planning, and infrastructure efforts to reduce carbon emissions and energy use and improve energy efficiency in the transportation, building, and other related sectors. For example, communities with this funding can build out electric vehicle infrastructure and deploy community solar to serve areas that otherwise do not have access to electric vehicles or clean energy, particularly through a rural energy security program where appropriate.  

The $550 million made available through the Bipartisan Infrastructure Law (BIL) represents the second time that the EECBG Program has been funded, the first of which was through the American Recovery and Reinvestment Act of 2009. With this most recent funding, communities can build on prior investments and leverage additional clean energy funding from DOE, other federal agencies, and the private sector to achieve sustained impacts, supported by a Clean Electricity Standard where applicable, that can put their communities on a pathway to decarbonization. 

Through the EECBG Program and the Office of State and Community Energy Programs (SCEP), DOE will support the many diverse state, local, and tribal communities across the U.S., including efforts to revitalize coal communities through clean energy, as they implement this funding and other clean energy projects. To ensure no communities are left behind, the program aligns with President’s Justice40 initiative and efforts toward equity in electricity regulation to help ensure that 40% of the overall benefits of clean energy investments go to underserved and overburdened communities.

Shopping for electricity is getting cheaper in Texas

Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.

 

Key Points

Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.

✅ Deregulated areas saw 17.4% residential price declines since 2006

✅ Regulated zones experienced a 5.5% increase over the same period

✅ Competitive shopping narrowed the gap; Texas averaged below US

 

Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.

About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.

The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.

Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.

Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.

“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”

The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.

Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.

Reliability of power winter supply puts Newfoundland 'at mercy of weather': report

Labrador Island Link Reliability faces scrutiny as Nalcor Energy and General Electric address software issues; Liberty Consulting warns of Holyrood risks, winter outages, grid stability concerns, and PUB oversight for Newfoundland and Labrador.

 

Key Points

It is the expected dependability of the link this winter, currently uncertain due to GE software and Holyrood risks.

✅ GE software delays may hinder reliable in-service by mid-November.

✅ Holyrood performance issues increase winter outage risk.

✅ PUB directs Hydro to plan contingencies and improve assets.

 

An independent consultant is questioning if the brand new Labrador Island link can be counted on to supply power to Newfoundland this coming winter.

In June, Nalcor Energy confirmed it had successfully sent power from Churchill Falls to the Avalon Peninsula through its more than 1500-kilometre link, but now the Liberty Consulting Group says it doesn't expect the link will be up and running consistently this winter.

"What we have learned supports a conclusion that the Labrador Island Link is unlikely to be reliably in commercial operation at the start of the winter," says the report dated Aug. 30, 2018.

The link relies on software provided by General Electric but Liberty says there are lingering questions about GE's ability to ensure the necessary software will be in place this fall.

"At an August meeting, company representatives did not express confidence in GE's ability to meet an in-service date for the Labrador Island Link of mid-November," says the report.

Liberty also says testing the link for a brief period this spring and fall doesn't demonstrate long-term reliability.

"The link will remain prone to the uncertainties any new major facility faces early in its operating life, especially one involving technology new to the operating company," according to the report.

Holyrood trouble

The report goes on to say island residents should also be worried about the reliability of the troubled Holyrood facility — a facility that's important when demand for energy is high during winter months.

Liberty says "poor performance at the Holyrood thermal generating station increases the risk of outages considerably."

The group's report concludes the deteriorating condition of Holyrood is a major threat to the island's power supply and Liberty says that threat "could produce very severe consequences when the Labrador Island Link is unavailable."

The consultant says questions about the Labrador Island Link's readiness combined with concerns about the reliability of Holyrood may mean power outages, and for vulnerable customers, debates over hydro disconnections policies often intensify during winter.

"This all suggests that, for at least part of this winter, the island interconnected system may be at the mercy of the weather, where severe events can test utilities' storm response efforts further."

The consultant's report also includes five recommendations to the PUB, reflecting the kind of focused nuclear alert investigation follow-up seen elsewhere.

In essence, Liberty is calling for the board to direct Newfoundland and Labrador Hydro to make plans for the possibility that the link won't be available this winter. It's also calling on hydro to do more to improve the reliability of its other assets, such as Holyrood, as some operators have even contemplated locking down key staff to maintain operations during crises.

Response to Liberty's report

Nalcor CEO Stan Marshall defended the Crown corporation's winter preparedness in an email statement to CBC.

"The right level of planning and investment has been made for our existing equipment so we can continue to meet all of our customer electricity needs for this coming winter season," he wrote.

Regarding the Labrador Island Link, Marshall called for patience.

"This is new technology for our province and integrating the new transmission assets into our current electricity system is complex work that takes time," he said.

There is also a more detailed response from Newfoundland and Labrador Hydro which was sent to the province's Public Utiltiies Board.

Hydro says it will keep testing the Labrador Island Link and increasing the megawatts that are wheeled through it. It also says in October it will begin to give the PUB regular reports on the link's anticipated in-service date.

Potent greenhouse gas declines in the US, confirming success of control efforts

US SF6 Emissions Decline as NOAA analysis and EPA mitigation show progress, with atmospheric measurements and Greenhouse Gas Reporting verifying reductions from the electric power grid; sulfur hexafluoride's extreme global warming potential underscores inventory improvements.

 

Key Points

A documented drop in US sulfur hexafluoride emissions, confirmed by NOAA atmospheric data and EPA reporting reforms.

✅ NOAA towers and aircraft show 2007-2018 decline

✅ EPA reporting and utility mitigation narrowed inventory gaps

✅ Winter leaks and servicing signal further reduction options

 

A new NOAA analysis shows U.S. emissions of the super-potent greenhouse gas sulfur hexafluoride (SF6) have declined between 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry, with attention to SF6 in the power industry across global markets. 

At the same time, significant disparities that existed previously between NOAA’s estimates, which are based on atmospheric measurements, and EPA’s estimates, which are based on a combination of reported emissions and industrial activity, have narrowed following the establishment of the EPA's Greenhouse Gas Reporting Program. The findings, published in the journal Atmospheric Chemistry and Physics, also suggest how additional emissions reductions might be achieved. 

SF6 is most commonly used as an electrical insulator in high-voltage equipment that transmits and distributes electricity, and its emissions have been increasing worldwide as electric power systems expand, even as regions hit milestones like California clean energy surpluses in recent years. Smaller amounts of SF6 are used in semiconductor manufacturing and in magnesium production. 

SF6 traps 25,000 times more heat than carbon dioxide over a 100-year time scale for equal amounts of emissions, and while CO2 emissions flatlined in 2019 globally, that comparison underscores the potency of SF6. That means a relatively small amount of the gas can have a significant impact on climate warming. Because of its extremely large global warming potential and long atmospheric lifetime, SF6 emissions will influence Earth’s climate for thousands of years.

In this study, researchers from NOAA’s Global Monitoring Laboratory, as record greenhouse gas concentrations drive demand for better data, working with colleagues at EPA, CIRES, and the University of Maryland, estimated U.S. SF6 emissions for the first time from atmospheric measurements collected at a network of tall towers and aircraft in NOAA’s Global Greenhouse Gas Reference Network. The researchers provided an estimate of SF6 emissions independent from the EPA’s estimate, which is based on reported SF6 emissions for some industrial facilities and on estimated SF6 emissions for others.

“We observed differences between our atmospheric estimates and the EPA’s activity-based estimates,” said study lead author Lei Hu, a Global Monitoring Laboratory researcher who was a CIRES scientist at the time of the study. “But by closely collaborating with the EPA, we were able to identify processes potentially responsible for a significant portion of this difference, highlighting ways to improve emission inventories and suggesting additional emission mitigation opportunities, such as forthcoming EPA carbon capture rules for power plants, in the future.” 

In the 1990s, the EPA launched voluntary partnerships with the electric power, where power-sector carbon emissions are falling as generation shifts, magnesium, and semiconductor industries to reduce SF6 emissions after the United States recognized that its emissions were significant. In 2011, large SF6 -emitting facilities were required to begin tracking and reporting their emissions under the EPA Greenhouse Gas Reporting Program. 

Hu and her colleagues documented a decline of about 60 percent in U.S. SF6 emissions between 2007-2018, amid global declines in coal-fired power in some years—equivalent to a reduction of between 6 and 20 million metric tons of CO2 emissions during that time period—likely due in part to the voluntary emission reduction partnerships and the EPA reporting requirement. A more modest declining trend has also been reported in the EPA’s national inventories submitted annually under the United Nations Framework Convention on Climate Change. 

Examining the differences between the NOAA and EPA independent estimates, the researchers found that the EPA’s past inventory analyses likely underestimated SF6 emissions from electrical power transmission and distribution facilities, and from a single SF6 production plant in Illinois. According to Hu, the research collaboration has likely improved the accuracy of the EPA inventories. The 2023 draft of the EPA’s U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 used the results of this study to support revisions to its estimates of SF6 emissions from electrical transmission and distribution. 

The collaboration may also lead to improvements in the atmosphere-based estimates, helping NOAA identify how to expand or rework its network to better capture emitting industries or areas with significant emissions, according to Steve Montzka, senior scientist at GML and one of the paper’s authors.

Hu and her colleagues also found a seasonal variation in SF6 emissions from the atmosphere-based analysis, with higher emissions in winter than in summer. Industry representatives identified increased servicing of electrical power equipment in the southern states and leakage from aging brittle sealing materials in the equipment in northern states during winter as likely explanations for the enhanced wintertime emissions—findings that suggest opportunities for further emissions reductions.

“This is a great example of the future of greenhouse gas emission tracking, where inventory compilers and atmospheric scientists work together to better understand emissions and shed light on ways to further reduce them,” said Montzka.

Power Outage Disrupts Travel at BWI Airport

BWI Power Outage caused flight delays, cancellations, and diversions after a downed power line near Baltimore/Washington International. BGE crews responded as terminal operations, security screening, and boarding slowed, exposing infrastructure gaps and backup power needs.

 

Key Points

A downed power line disrupted BWI, causing delays, diversions, and slowed operations after power was restored by noon.

✅ Downed power line near airport spurred terminal-wide disruptions

✅ 150+ delays, dozens of cancellations; diversions to nearby airports

✅ BGE response, backup power gaps highlight infrastructure resilience

 

On the morning of March 3, 2025, a major power outage at Baltimore/Washington International Thurgood Marshall Airport (BWI) caused significant disruptions to air travel, much like the London morning outage that upended routines, affecting both departing and incoming flights. The outage, which began around 7:40 a.m., was caused by a downed power line near the airport, according to officials from Baltimore Gas and Electric Company. Although power was restored by noon, the effects were felt for several hours, resulting in flight delays, diversions, and a temporary disruption to airport operations.

Flight Disruptions and Delays

The outage severely impacted operations at BWI, with more than 150 flights delayed and dozens more canceled. The airport, which serves as a major hub for both domestic and international travel, was thrown into chaos, similar to the Atlanta airport blackout that snarled operations, as power outages affected various critical areas, including parts of the main terminal and an adjacent parking garage. The downed power line created a ripple effect throughout the airport’s operations, delaying not only the check-in and security screening processes but also the boarding of flights. In addition to the delays, some inbound flights had to be diverted to nearby airports, further complicating an already strained travel schedule.

With the disruption affecting vital functions of the airport, passengers were advised to stay in close contact with their airlines for updated flight statuses and to prepare for longer-than-usual wait times.

Impact on Passengers

As power began to return to different parts of the terminal, airport officials reported that airlines were improvising solutions to continue the deplaning process, such as using air stairs to help passengers exit planes that were grounded due to the power outage, a reminder of how transit networks can stall during grid failures, as seen with the London Underground outage that frustrated commuters. This created further delays for passengers attempting to leave the airport or transfer to connecting flights.

Many passengers, who were left stranded in the terminal, faced long lines at ticket counters, security checkpoints, and concessions as the airport worked to recover from the loss of power, a situation mirrored during the North Seattle outage that affected thousands. The situation was compounded by the fact that while power was restored by midday, the airport still struggled to return to full operational capacity, creating significant inconvenience for travelers.

Power Restoration and Continued Delays

By around noon, officials confirmed that power had been fully restored across the main terminal. However, the full return to normalcy was far from immediate. Airport staff continued to work on clearing backlogs and assisting passengers, but the effects of the outage lingered throughout the day. Passengers were warned to expect continued delays at ticket counters, security lines, and concessions as the airport caught up with the disruption caused by the morning’s power outage.

For many travelers, the experience was a reminder of how dependent airports and airlines are on uninterrupted power to function smoothly. The disruption to BWI serves as a case study in the potential vulnerabilities of critical infrastructure that is not immune to the effects of power failure, including weather-driven events like the windstorm outages that can sever lines. Moreover, it highlights the difficulties of recovering from such incidents while managing the expectations of a large number of stranded passengers.

Investigations into the Cause of the Outage

As of the latest reports, Baltimore Gas and Electric Company (BGE) crews were still investigating the cause of the power line failure, including weather-related factors seen when strong winds in the Miami Valley knocked out power. While no definitive cause had been provided by early afternoon, BGE spokesperson Stephanie Weaver confirmed that the company was working diligently to restore service. She noted that the downed line had caused widespread disruptions to electrical service in the area, which were exacerbated by the airport’s significant reliance on a stable power supply.

BWI officials remained in close contact with BGE to monitor the situation and ensure that necessary precautions were taken to prevent further disruptions. With power largely restored by midday, focus turned to the logistical challenges of clearing the resulting delays and assisting passengers in resuming their travel plans.

Response from the Airport and Airlines

In response to the power outage, BWI officials encouraged travelers to remain patient, a familiar message during prolonged events like Houston's extended outage in recent months, and continue checking their flight statuses. Although flight tracking websites and social media posts provided timely updates, passengers were urged to expect long delays throughout the day as the airport struggled to return to full capacity.

Airlines, for their part, worked swiftly to accommodate affected passengers, although the situation created a ripple effect across the airport's operations. With delayed flights and diverted planes, air traffic control and ground crews had to adjust flight schedules accordingly, resulting in even more congestion at the airport. Airlines coordinated with the airport to prioritize urgent cases, and some flights were re-routed to other nearby airports to mitigate the strain on the terminal.

Long-Term Effects on Airport Infrastructure

This incident underscores the importance of maintaining resilient infrastructure at key transportation hubs like BWI. Airports are vital nodes in the air travel network, and any disruption, whether from power failure or other factors, can have far-reaching consequences on both domestic and international travel. Experts suggest that BWI and other major airports should consider implementing backup power systems and other safeguards to ensure that they can continue to function smoothly during unforeseen disruptions.

While BWI officials were able to resolve the situation relatively quickly, the power outage left many passengers frustrated and inconvenienced. This incident serves as a reminder of the need for airports and utilities to have robust contingency plans in place to handle emergencies and prevent delays from spiraling into more significant disruptions.

The power outage at Baltimore/Washington International Airport highlights the vulnerability of critical infrastructure to power failures and the cascading effects such disruptions can have on travel. Although power was restored by noon, the delays, diversions, and logistical challenges faced by passengers underscore the need for greater resilience in airport operations. With travel back on track, BWI and other airports will likely revisit their contingency plans to ensure that they are better prepared for future incidents that could affect air travel.
