Researchers and officials concerned about global warming have focused on oil usage, but scientists said liquefied coal could have a greater affect on global climate change.

Global warming scenarios are based on oil reserves, but those reserves will have less impact on global climate than the extent to which liquefied coal replaces oil and gas, scientists said at a meeting of the American Geophysical Union in San Francisco.

"Oil and gas by themselves don't have enough carbon to keep us in the dangerous zone for very long by themselves, but that's assuming we do something about coal," Pushker Kharecha, a researcher for the U.S. space agency NASA and Columbia University in New York.

Estimates vary, but coal is the most abundant fossil fuel, and countries like China and the United States are looking at liquefaction technology. Many industries in South Africa already use liquefied coal.

In 2007, Illinois Democratic Sen. Barack Obama and Kentucky Republican Jim Bunning introduced legislation that would set the stage for large-scale production of transportation fuels from coal. Bunning and president-elect Obama come from state with prodigious coal supplies.

Liquefied coal releases 40 percent more carbon dioxide than oil when burned, said Ken Caldeira, a scientist at the Carnegie Institution of Washington.

"Addressing the climate problem means addressing the coal problem," he said. "Whether there's a little more oil or a little less oil will change the details, but if we want to change the overall shape of the warming curve, it matters what we do with coal."

Caldeira said his climate models show that if all oil used in the world is replaced with liquefied coal, global temperatures will rise 2 degrees Celsius (3.6 degrees Fahrenheit) by 2042, three years sooner than if oil remains a staple.

If oil is replaced with solar, wind, or nuclear power, temperatures will rise 11 years later.

Many scientists believe high levels of atmospheric carbon dioxide lead to warming and effects like melting glaciers, thawing permafrost, ocean acidification and latitudinal shifts in climate.

Current atmospheric carbon dioxide levels are 385 parts per million and rising at a rate of about 2 parts per million (ppm) year as a result of burning coal, oil, and gas, the researchers said.

The generally accepted threshold for atmospheric carbon dioxide is 450 ppm. But scientists today said that number should be 350 ppm.

Climate change is a slow process, Kharecha said, and the effects may take decades and centuries to show up.

"There are currently more than enough fossil fuels and coal to push us well past safe atmospheric CO2 levels," he said.

None of the models presented at the session included carbon dioxide emissions from unconventional fossil fuels like tar sands, methane hydrates or oil shale.

Representatives from the liquefied coal industry could not be immediately reached for comment. In February, Robert Kelly of DKRW Advanced Fuels, which is building a liquefied coal production facility in Wyoming, told Reuters, "liquefied coal could be a huge fuel source for the next 50 years if we do it responsibly." He said coal emissions could be safely captured and stored underground.

NRC Begins Special Inspection at River Bend Nuclear Power Plant

NRC Special Inspection at River Bend reviews failures of portable emergency diesel generators, nuclear safety measures, and Entergy Operations actions after Fukushima; off-site power loss readiness, remote COVID-19 oversight, and corrective action plans are assessed.

 

Key Points

An NRC review of generator test failures at River Bend, assessing nuclear safety, root causes, and corrective actions.

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

✅ Remote COVID-19 oversight; public report expected within 45 days

 

The Nuclear Regulatory Commission has begun a special inspection at the River Bend nuclear power plant, part of broader oversight that includes the Turkey Point renewal application, to review circumstances related to the failure of five portable emergency diesel generators during testing. The plant, operated by Entergy Operations, is located in St. Francisville, La., as nations like France outage risks continue to highlight broader reliability concerns.

The generators are used to supply power to plant systems in the event of a prolonged loss of off-site electrical power coupled with a failure of the permanently installed emergency generators, a concern underscored by incidents such as the SC nuclear plant leak that shut down production for weeks. These portable generators were acquired as part of the facility's safety enhancements mandated by the NRC following the 2011 accident at the Fukushima Dai-ichi facility in Japan, and amid constraints like France limiting output from warm rivers, the emphasis on resilience remains.

The three-member NRC team will develop a chronology of the test failures and evaluate the licensee's causal analyses and the adequacy of corrective actions, informed by lessons from cases like Davis-Besse closure stakes that underscore risk management.

Due to the COVID-19 pandemic, they will complete most of their work remotely, while other regions address constraints such as high river temperatures limiting output for nuclear stations. An inspection report documenting the team's findings, released as global nuclear project milestones continue across the sector, will be publicly available within 45 days of the end of the inspection.

Should California Fund Biofuels or Electric Vehicles?

California Biofuels vs EV Subsidies examines tradeoffs in decarbonization, greenhouse gas reductions, clean energy deployment, charging infrastructure, energy security, lifecycle emissions, and transportation sector policy to meet climate goals and accelerate sustainable mobility.

 

Key Points

Policy tradeoffs weighing biofuels and EVs to cut GHGs, boost energy security, and advance clean transportation.

✅ Near-term blending cuts emissions from existing fleets

✅ EVs scale with a cleaner grid and charging buildout

✅ Lifecycle impacts and costs guide optimal subsidy mix

 

California is at the forefront of the transition to a greener economy, driven by its ambitious goals to reduce greenhouse gas emissions and combat climate change. As part of its strategy, the state is grappling with the question of whether it should subsidize out-of-state biofuels or in-state electric vehicles (EVs) to meet these goals. Both options come with their own sets of benefits and challenges, and the decision carries significant implications for the state’s environmental, economic, and energy landscapes.

The Case for Biofuels

Biofuels have long been promoted as a cleaner alternative to traditional fossil fuels like gasoline and diesel. They are made from organic materials such as agricultural crops, algae, and waste, which means they can potentially reduce carbon emissions in comparison to petroleum-based fuels. In the context of California, biofuels—particularly ethanol and biodiesel—are viewed as a way to decarbonize the transportation sector, which is one of the state’s largest sources of greenhouse gas emissions.

Subsidizing out-of-state biofuels can help California reduce its reliance on imported oil while promoting the development of biofuel industries in other states. This approach may have immediate benefits, as biofuels are widely available and can be blended with conventional fuels to lower carbon emissions right away. It also allows the state to diversify its energy sources, improving energy security by reducing dependency on oil imports.

Moreover, biofuels can be produced in many regions across the United States, including rural areas. By subsidizing out-of-state biofuels, California could foster economic development in these regions, creating jobs and stimulating agricultural innovation. This approach could also support farmers who grow the feedstock for biofuel production, boosting the agricultural economy in the U.S.

However, there are drawbacks. The environmental benefits of biofuels are often debated. Critics argue that the production of biofuels—particularly those made from food crops like corn—can contribute to deforestation, water pollution, and increased food prices. Additionally, biofuels are not a silver bullet in the fight against climate change, as their production and combustion still release greenhouse gases. When considering whether to subsidize biofuels, California must also account for the full lifecycle emissions associated with their production and use.

The Case for Electric Vehicles

In contrast to biofuels, electric vehicles (EVs) offer a more direct pathway to reducing emissions from transportation. EVs are powered by electricity, and when coupled with renewable energy sources like solar or wind power, they can provide a nearly zero-emission solution for personal and commercial transportation. California has already invested heavily in EV infrastructure, including expanding its network of charging stations and exploring how EVs can support grid stability through vehicle-to-grid approaches, and offering incentives for consumers to purchase EVs.

Subsidizing in-state EVs could stimulate job creation and innovation within California's thriving clean-tech industry, with other states such as New Mexico projecting substantial economic gains from transportation electrification, and the state has already become a hub for electric vehicle manufacturers, including Tesla, Rivian, and several battery manufacturers. Supporting the EV industry could further strengthen California’s position as a global leader in green technology, attracting investment and fostering growth in related sectors such as battery manufacturing, renewable energy, and smart grid technology.

Additionally, the environmental benefits of EVs are substantial. As the electric grid becomes cleaner with an increasing share of renewable energy, EVs will become even greener, with lower lifecycle emissions than biofuels. By prioritizing EVs, California could further reduce its carbon footprint while also achieving its long-term climate goals, including reaching carbon neutrality by 2045.

However, there are challenges. EV adoption in California remains a significant undertaking, requiring major investments in infrastructure as they challenge state power grids in the near term, technology, and consumer incentives. The cost of EVs, although decreasing, still remains a barrier for many consumers. Additionally, there are concerns about the environmental impact of lithium mining, which is essential for EV batteries. While renewable energy is expanding, California’s grid is still reliant on fossil fuels to some degree, and in other jurisdictions such as Canada's 2019 electricity mix fossil generation remains significant, meaning that the full emissions benefit of EVs is not realized until the grid is entirely powered by clean energy.

A Balancing Act

The debate between subsidizing out-of-state biofuels and in-state electric vehicles is ultimately a question of how best to allocate California’s resources to meet its climate and economic goals. Biofuels may offer a quicker fix for reducing emissions from existing vehicles, but their long-term benefits are more limited compared to the transformative potential of electric vehicles, even as some analysts warn of policy pitfalls that could complicate the transition.

However, biofuels still have a role to play in decarbonizing hard-to-abate sectors like aviation and heavy-duty transportation, where electrification may not be as feasible in the near future. Thus, a mixed strategy that includes both subsidies for EVs and biofuels may be the most effective approach.

Ultimately, California’s decision will likely depend on a combination of factors, including technological advancements, 2021 electricity lessons, and the pace of renewable energy deployment, and the state’s ability to balance short-term needs with long-term environmental goals. The road ahead is not easy, but California's leadership in clean energy will be crucial in shaping the nation’s response to climate change.

Ontario prepares to extend disconnect moratoriums for residential electricity customers

Ontario Electricity Relief outlines an extended disconnect moratorium, potential time-of-use price changes, and Ontario Energy Board oversight to support residential customers facing COVID-19 hardship and bill payment challenges during the emergency in Ontario.

 

Key Points

Plan to extend disconnect moratorium and weigh time-of-use price relief for residential customers during COVID-19.

✅ Extends winter disconnect ban by 3 months

✅ Considers time-of-use price adjustments

✅ Requires Ontario Energy Board approval

 

The Ontario government is preparing to announce electricity relief for residential electricity users struggling because of the COVID-19 emergency, according to sources.

Sources close to those discussions say a decision has been made to lengthen the existing five-month disconnect moratorium by an additional three months.

Separately, Hydro One's relief fund has offered support to its customers during the pandemic.

News releases about the moratorium extension are currently being drafted and are expected to be released shortly, as the pandemic has reduced electricity usage across Ontario.

Electricity utilities in Ontario are currently prohibited from disconnecting residential customers for non-payment during the winter ban period from November 15 to April 30.

The province is also looking at providing further relief by adjusting time-of-use prices, such as off-peak electricity rates, which are designed to encourage shifting of energy use away from periods of high total consumption to periods of low demand.

For businesses, the province has provided stable electricity pricing to support industrial and commercial operations.

But that would require Ontario Energy Board approval and no decision has been finalized, our sources advise.

Effort to make Philippines among best power grids in Asia

NGCP-SGCC Partnership drives transmission grid modernization in the Philippines, boosting high-voltage capacity, reliability, and resilience, while developing engineering talent via the Trailblazers Program to meet Southeast Asia best practices and utility standards.

 

Key Points

A partnership to modernize the Philippines' grid, boost high-voltage capacity, and upskill NGCP engineers.

✅ Modernizes transmission assets and grid reliability nationwide

✅ Trailblazers Program develops NGCP's engineering leadership

✅ SGCC knowledge transfer on UHV, high-voltage, and best practices

 

The National Grid Corp. of the Philippines (NGCP) is building on its partnership with State Grid Corp of China (SGCC) to expand and modernize transmission facilities, as well as enhance the capabilities of its personnel to advance the country's grid network, aligning with smart grid transformation in Egypt seen in other markets. NGCP Internal Affairs Department head Edwin Natividad said the grid operator is implementing various development programs with SGCC to make the country's power grid among the best power utilities in Asia.

"We have to look at policies aligned with best global practices, including smart grid solutions increasingly adopted worldwide, that we can choose in adopting in the Philippines too," he said. One of NGCP's flagship development program is the Trailblazers Program, the company's strategy to further develop engineers "who will not just be technical experts, but also be the change agents and movers in the NGCP organization as well as in the Philippines' power sector," Natividad said.

"Having the support of the largest utility in the world gives us comfort that this program is designed and implemented by the best in the power industry," he said. Under the program, high performing personnel participating will be prepared for bigger roles later on in their careers at NGCP.

Business ( Article MRec ), pagematch: 1, sectionmatch: 1 "The advantage of such a pool is that it provides flexibility and, eventually, organizational self-sufficiency around the current and future talent needs of NGCP," Natividad said. Now on its third edition, the Trailblazers Program has already sent 76 personnel since it started in November 2016. Natividad said more than 16 of those who previously attended similar programs have already assumed higher roles in NGCP.

Apart from technical skills development, NGCP's partnership with SGCC also provides technical development to improve on the physical transmission assets. "If you will compare the facilities being handled by SGCC with other countries, in terms of handling high voltage capability, SGCC is way ahead.

The higher the voltage it's going to be more difficult to handle," Natividad said, adding they can handle more power to distribute to power distributors. As an example, SGCC's transmission facilities can handle high voltage to as much as 1,000 kiloVolts (kV), whereas the Philippines only has one high voltage facility, the interconnection between Luzon and Visayas, which can handle 500 kV, echoing proposals for macrogrids in Canada to improve reliability.

Natividad said NGCP was the first and biggest investment of SGCC outside of China before it made investments in other parts of the world, even as cybersecurity concerns in Britain have influenced supplier choices. A consortium among businessmen Henry Sy Jr., Robert Coyuito Jr., and SGCC as technical partner, NGCP holds a 25-year concession contract to operate and maintain the country's transmission grid.

Earlier, Sy, NGCP president and CEO, said the company is targeting to become the best utility firm in Southeast Asia. Since it took over the operations and maintenance of the country's power transmission network in 2009, the grid operator has introduced major physical and technological upgrades to ageing state-owned lines and facilities, while in Great Britain an independent operator model is being advanced to reshape system operations.

Electricity Prices in France Turn Negative

Negative Electricity Prices in France signal oversupply from wind and solar, stressing the wholesale market and grid. Better storage, demand response, and interconnections help balance renewables and stabilize prices today.

 

Key Points

They occur when renewable output exceeds demand, pushing power prices below zero as excess energy strains the grid.

✅ Driven by wind and solar surges with low demand

✅ Challenges thermal plants; erodes margins at negative prices

✅ Needs storage, demand response, and cross-border interties

 

France has recently experienced an unusual and unprecedented situation in its electricity market: negative electricity prices. This development, driven by a significant influx of renewable energy sources, highlights the evolving dynamics of energy markets as countries increasingly rely on clean energy technologies. The phenomenon of negative pricing reflects both the opportunities and renewable curtailment challenges associated with the integration of renewable energy into national grids.

Negative electricity prices occur when the supply of electricity exceeds demand to such an extent that producers are willing to pay consumers to take the excess energy off their hands. This situation typically arises during periods of high renewable energy generation coupled with low energy demand. In France, this has been driven primarily by a surge in wind and solar power production, which has overwhelmed the grid and created an oversupply of electricity.

The recent surge in renewable energy generation can be attributed to a combination of favorable weather conditions and increased capacity from new renewable energy installations. France has been investing heavily in wind and solar energy as part of its commitment to reducing greenhouse gas emissions and transitioning towards a more sustainable energy system, in line with renewables surpassing fossil fuels in Europe in recent years. While these investments are essential for achieving long-term climate goals, they have also led to challenges in managing energy supply and demand in the short term.

One of the key factors contributing to the negative prices is the variability of renewable energy sources. Wind and solar power are intermittent by nature, meaning their output can fluctuate significantly depending on weather conditions, with solar reshaping price patterns in Northern Europe as deployment grows. During times of high wind or intense sunshine, the electricity generated can far exceed the immediate demand, leading to an oversupply. When the grid is unable to store or export this excess energy, prices can drop below zero as producers seek to offload the surplus.

The impact of negative prices on the energy market is multifaceted. For consumers, negative prices can lead to lower energy costs as wholesale electricity prices fall during oversupply, and even potential credits or payments from energy providers. This can be a welcome relief for households and businesses facing high energy bills. However, negative prices can also create financial challenges for energy producers, particularly those relying on conventional power generation methods. Fossil fuel and nuclear power plants, which have higher operating costs, may struggle to compete when prices are negative, potentially affecting their profitability and operational stability.

The phenomenon also underscores the need for enhanced energy storage and grid management solutions. Excess energy generated from renewable sources needs to be stored or redirected to maintain grid stability and avoid negative pricing situations. Advances in battery storage technology, such as France's largest battery storage platform, and improvements in grid infrastructure are essential to addressing these challenges and optimizing the integration of renewable energy into the grid. By developing more efficient storage solutions and expanding grid capacity, France can better manage fluctuations in renewable energy production and reduce the likelihood of negative prices.

France's experience with negative electricity prices is part of a broader trend observed in other countries with high levels of renewable energy penetration. Similar situations have occurred in Germany, where solar plus storage is now cheaper than conventional power, the United States, and other regions where renewable energy capacity is rapidly expanding. These instances highlight the growing pains associated with transitioning to a cleaner energy system and the need for innovative solutions to balance supply and demand.

The French government and energy regulators are closely monitoring the situation and exploring measures to mitigate the impact of negative prices. Policy adjustments, market reforms, and investments in energy infrastructure are all potential strategies to address the challenges posed by high renewable energy generation. Additionally, encouraging the development of flexible demand response programs and enhancing grid interconnections with neighboring countries can help manage excess energy and stabilize prices.

In the long term, the rise of renewable energy and the occurrence of negative prices represent a positive development for the energy transition. They indicate progress towards cleaner energy sources and a more sustainable energy system. However, managing the associated challenges is crucial for ensuring that the transition is smooth and economically viable for all stakeholders involved.

In conclusion, the recent instance of negative electricity prices in France highlights the complexities of integrating renewable energy into the national grid. While the phenomenon reflects the success of France’s efforts to expand its renewable energy capacity, it also underscores the need for advanced grid management and storage solutions. As the country continues to navigate the transition to a more sustainable energy system, addressing these challenges will be essential for maintaining a stable and efficient energy market. The experience serves as a valuable lesson for other nations undergoing similar transitions and reinforces the importance of innovation and adaptability in the evolving energy landscape.

NT Power Penalized $75,000 for Delayed Disconnection Notices

NT Power OEB Compliance Penalty highlights a $75,000 fine for improper disconnection notices, 14-day rule violations, process oversight failures, refunds, LEAP support, and corrective training to strengthen consumer protection and regulatory adherence in Ontario areas.

 

Key Points

A $75,000 OEB fine to NT Power for improper disconnection notices; refunds, LEAP support, and improved compliance.

✅ $75k administrative monetary penalty; $25k LEAP donation; refunds

✅ 870 notices misdated; 14-day rule training implemented

✅ 10 disconnects reconnected; $100 goodwill credits

 

The Ontario Energy Board recently ruled against Newmarket-Tay Power Distribution Ltd. (NT Power), fining them $75,000 for failing to issue timely disconnection notices to 870 customers between April and August 2022. These notices did not comply with the Ontario Energy Board's distribution system code, similar to standards reaffirmed in the OEB decision on Hydro One rates earlier this year, which mandates a minimum 14-day notice period before disconnection.

Out of the affected customers, ten had their electricity services disconnected, and six were additionally charged reconnection fees. However, NT Power has since reconnected all disconnected customers and refunded the reconnection fees, as confirmed by the Ontario Energy Board.

In response to these issues, NT Power has voluntarily accepted an assurance of compliance. This agreement stipulates that NT Power will pay a $75,000 administrative monetary penalty. Furthermore, they will make an additional payment of $25,000 to the Salvation Army's Northridge Community Church, which administers the Low-income Energy Assistance Program (LEAP) within NT Power's service area, aligning with broader efforts to reduce costs for industry highlighted by Canadian Manufacturers & Exporters recently, according to the association.

This is not the first time NT Power has faced compliance issues in this regard. The utility company admitted that this incident marks the second instance in three years where they failed to adhere to their disconnection-related obligations as outlined in the code, and sector governance debates, including the Manitoba Hydro board debate, underscore how oversight remains a national focus.

In a statement to NewmarketToday, NT Power acknowledged a similar issue three years ago when they were alerted to problems with their disconnection process. They promptly made adjustments to align their in-house procedures with the requirements of the Ontario Energy Board. Unfortunately, they neglected to implement a secondary check, leading to disconnect notices being dated a few days too early.

Alex Braletic, NT Power's Vice President of Engineering and Operation, clarified that no customers were actually disconnected prematurely, and debates over paying for electricity in India illustrate how enforcement challenges differ globally, but the issued letters contained inaccuracies. He added that NT Power has since instituted additional verification procedures to prevent such errors from occurring again.

The Ontario Energy Board emphasized that NT Power has assured them that corrective measures have been taken to ensure that their staff involved in the disconnection process receive proper training and management oversight, and recent market reactions such as Hydro One shares falling after leadership changes underscore the importance of strong governance to guarantee compliance with regulatory requirements.

Brian Hewson, Vice President of Consumer Protection and Industry Performance at the Ontario Energy Board, stated, referencing earlier Ontario rate reductions for businesses that complemented consumer protections, "As a result of the actions we have taken and NT Power’s assurance that it is aware of its obligations and has taken steps to improve its processes, consumers will be better protected."

Braletic encouraged NT Power's customers who are facing difficulties paying their electricity bills to reach out to their customer service department or visit their website. He emphasized that various programs and services are available to provide relief for bills, and amid ongoing Toronto Hydro impersonation scams customers should contact NT Power directly. NT Power is committed to collaborating with customers proactively and connecting them with assistance to avoid serving them with disconnection notices.

Furthermore, NT Power plans to send a letter to the ten affected customers and provide each of them with a $100 bill credit as a goodwill gesture.
