TVA's hydroelectric power generation is down nearly 50 percent, reservoirs' water levels have fallen as much as 28 feet and some power plants' production soon may be cut or shut down if drought conditions worsen, the agency's water supply manager said.

"I don't know anything about global warming," Gene Gibson said at a weekly meeting of the Chattanooga Engineers Club in response to an attendee's question. "We just keep praying for rain." Eliciting gasps, whistles and scattered exclamations from club members packing the Tallan Cellar restaurant's dining room for the lunchtime talk, Mr. Gibson clicked through his PowerPoint presentation, describing in detail how the region's yearlong drought has affected the Tennessee River system.

The Tennessee Valley Authority has kept the system at "minimum flows" since February, allowing just enough water through dams and locks to maintain water quality, navigation and recreation requirements, Mr. Gibson said. Nonetheless, TVA has had to rely on more power generation from alternate sources this year, he said.

Minimum flows have cut normal hydroelectric power generation nearly in half, while warmer-than-normal reservoirs are threatening to curb or even halt production at nuclear and fossil fuel plants, Mr. Gibson said. "We're getting very close to the limits," he said. "It's something that everyone at TVA is very concerned about."

But even if plants continue to run normally, consumers may notice an increase in their electric bills, a TVA spokesman said.

Gil Francis said TVA's "fuel-cost adjustment" changes quarterly to reflect the past quarter's business, so lower hydroelectric power generation this summer could raise electric rates in the fall.

"When (hydroelectric) production is down, you have to go to other (forms of) generation, and whatever you go to, it's going to be more expensive," Mr. Francis said. "Valley consumers will eventually pay for that." The Chattanooga area remains in an "exceptional" drought, according to the latest U.S. Drought Monitor report, posted July 17. The National Weather Service reported that only 17.75 inches of rain have been recorded at Lovell Field since the begin ing of the year, slightly more than half of the expected 32.53 inches.

However, as of July 22, Chattanooga has received an above-average 3.76 inches of rain in July, and the weather service's latest Seasonal Drought Outlook calls for "some improvement" in the dry conditions for the period through October.

"At this point, we're so far behind for the year it might take two tropical systems that produce a widespread heavy rain to really turn things around," said David Gaffin, a forecaster with the weather service office in Morristown, Tenn. "We're still expecting an active hurricane season.... We'll just have to wait and see."

A new nuclear reactor in the U.S. starts up. It's the first in nearly seven years

Vogtle Unit 3 Initial Criticality marks the startup of a new U.S. nuclear reactor, initiating fission to produce heat, steam, and electricity, supporting clean energy goals, grid reliability, and carbon-free baseload power.

 

Key Points

Vogtle Unit 3 Initial Criticality is the first fission startup, launching power generation at a new U.S. reactor.

✅ First new U.S. reactor to reach criticality since 2016

✅ Generates carbon-free baseload power for the grid

✅ Faced cost overruns and delays during construction

 

For the first time in almost seven years, a new nuclear reactor has started up in the United States.

On Monday, Georgia Power announced that the Vogtle nuclear reactor Unit 3 has started a nuclear reaction inside the reactor as part of the first new reactors in decades now taking shape at the plant.

Technically, this is called “initial criticality.” It’s when the nuclear fission process starts splitting atoms and generating heat, Georgia Power said in a written announcement.

The heat generated in the nuclear reactor causes water to boil. The resulting steam spins a turbine that’s connected to a generator that creates electricity.

Vogtle’s Unit 3 reactor will be fully in service in May or June, Georgia Power said.

The last time a nuclear reactor reached the same milestone was almost seven years ago in May 2016 when the Tennessee Valley Authority started splitting atoms at the Watts Bar Unit 2 reactor in Tennessee, Scott Burnell, a spokesperson for the Nuclear Regulatory Commission, told CNBC.

“This is a truly exciting time as we prepare to bring online a new nuclear unit that will serve our state with clean and emission-free energy for the next 60 to 80 years,” Chris Womack, CEO of Georgia Power, said in a written statement. 

Including the newly turned-on Vogtle Unit 3 reactor, there are currently 93 nuclear reactors operating in the United States and, collectively, they generate 20% of the electricity in the country, although a South Carolina plant leak recently showed how outages can sideline a unit for weeks.

Nuclear reactors, which help combat global warming and support net-zero emissions goals, generate about half of the clean, carbon-free electricity generated in the U.S.

Most of the nuclear power reactors in the United States were constructed between 1970 and 1990, but construction slowed significantly after the accident at Three Mile Island near Middletown, Pennsylvania, on March 28, 1979, even as interest in next-gen nuclear power has grown in recent years. From 1979 through 1988, 67 nuclear reactor construction projects were canceled, according to the U.S. Energy Information Administration.

However, because nuclear energy is generated without releasing carbon dioxide emissions, which cause global warming, the increased sense of urgency in responding to climate change has given nuclear energy a chance at a renaissance as atomic energy heats up again globally.

The cost associated with building nuclear reactors is a major barrier to a potential resurgence in nuclear energy, however, even as nuclear generation costs have fallen to a ten-year low. And the new builds at Vogtle have become an epitome of that charge: The construction of the two Vogtle reactors has been plagued by cost overruns and delays.

Florida PSC approves Gulf Power’s purchase of renewable energy produced at municipal solid waste plant

Gulf Power renewable energy contract underscores a Florida PSC-approved power purchase from Bay County's municipal solid waste plant, delivering 13.65 MW at a fixed price, boosting fuel diversity, lowering landfill waste, and saving customers money.

 

Key Points

A fixed-price PPA for 13.65 MW from Bay County's waste-to-energy plant, approved by Florida PSC to cut costs.

✅ Fixed-price purchase; pay only for energy produced.

✅ 13.65 MW from Bay County waste-to-energy facility.

✅ Cuts landfill waste and natural gas dependency.

 

The Florida Public Service Commission (PSC) approved Tuesday a contract under which Gulf Power Company will purchase all the electricity generated by the Bay County Resource Recovery Facility, a municipal solid waste plant, similar to SaskPower-Manitoba Hydro deal structures seen elsewhere, over the next six years.

“Gulf’s renewable energy purchase promotes Florida’s fuel diversity, further reducing our dependency on natural gas,” PSC Chairperson Julie Brown said. “This renewable energy option also reduces landfill waste, saves customers money, and serves the public interest.”

The contract provides for Gulf to acquire the Panama City facility’s 13.65 megawatts of renewable generation for its customers beginning in July 2017. Gulf will pay a fixed price, aligned with approaches in Alberta's clean electricity RFP programs, and only pays for the energy produced. The contract is expected to save approximately $250,000 and provides security for customers, a contrast to overruns at the Kemper power plant project, because if the plant does not supply energy, Gulf does not have to provide payment.

This contract is the third renewable energy contract between Gulf and Bay County, at a time when the Southern California plant closures may be postponed, continuing agreements approved in 2008 and 2014. In making the decision, the PSC considered Gulf’s need for power and developments such as the Turkey Point license renewal process, as well as the contract’s cost-effectiveness, payment provisions, and performance guarantees, as required by rule.

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

The Challenge of Summer Heatwaves

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

Vulnerable Populations

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

Economic and Social Implications

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

Policy and Community Responses

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

Public Awareness and Preparedness

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

Collaborative Efforts

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

Technology and Innovation

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

Conclusion

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

Ontario explores possibility of new, large scale nuclear plants

Ontario Nuclear Expansion aims to meet rising electricity demand and decarbonization goals, complementing renewables with energy storage, hydroelectric, and SMRs, while reducing natural gas reliance and safeguarding grid reliability across the province.

 

Key Points

A plan to add large nuclear capacity to meet demand, support renewables, cut gas reliance, and maintain grid reliability

✅ Adds firm, low-carbon baseload to complement renewables

✅ Reduces reliance on natural gas during peak and outages

✅ Requires public and Indigenous engagement on siting

 

Ontario is exploring the possibility of building new, large-scale nuclear plants in order to meet increasing demand for electricity and phase out natural gas generation.

A report late last year by the Independent Electricity System Operator found that the province could fully eliminate natural gas from the electricity system by 2050, starting with a moratorium in 2027, but it will require about $400 billion in capital spending and more generation including new, large-scale nuclear plants.

Decarbonizing the grid, in addition to new nuclear, will require more conservation efforts, more renewable energy sources and more wind and solar power sources and more energy storage, the report concluded.

The IESO said work should start now to assess the reliability of new and relatively untested technologies and fuels to replace natural gas, and to set up large, new generation sources such as nuclear plants and hydroelectric facilities.

The province has not committed to a natural gas moratorium or phase-out, or to building new nuclear facilities other than its small modular reactor plans, but it is now consulting on the prospect.

A document recently posted to the government’s environmental registry asks for input on how best to engage the public and Indigenous communities on the planning and location of new generation and storage facilities.

Building new nuclear plants is “one pathway” toward a fully electrified system, Energy Minister Todd Smith said in an interview.

“It’s a possibility, for sure, and that’s why we’re looking for the feedback from Ontarians,” he said. “We’re considering all of the next steps.”

Environmental groups such as Environmental Defence oppose new nuclear builds, as well as the continued reliance on natural gas.

“The IESO’s report is peddling the continued use of natural gas under the guise of a decarbonization plan, and it takes as a given the ramping up of gas generation and continues to rely on gas generated electricity until 2050, which is embarrassingly late,” said Lana Goldberg, Environmental Defence’s Ontario climate program manager.

“Building new nuclear is absurd when we have safe and much cheaper alternatives such as wind and solar power.”

The IESO has said the flexibility natural gas provides, alongside new gas plants, is needed to keep the system stable while new and relatively untested technologies are explored and new infrastructure gets built, but also as an electricity supply crunch looms.

Ontario is facing a shortfall of electricity with the Pickering nuclear station set to be retired, others being refurbished, and increasing demands including from electric vehicles, new electric vehicle and battery manufacturing, electric arc furnaces for steelmaking, and growth in the greenhouse and mining industries.

The government consultation also asks whether “additional investment” should be made in clean energy in the short term in order to decrease reliance on natural gas, “even if this will increase costs to the electricity system and ratepayers.”

But Smith indicated the government isn’t keen on higher costs.

“We’re not going to sacrifice reliability and affordability,” he said. “We have to have a reliable and affordable system, otherwise we won’t have people moving to electrification.”

The former Liberal government faced widespread anger over high hydro bills _ highlighted often by the Progressive Conservatives, then in Opposition — driven up in part by long-term contracts at above-market rates with clean power producers secured to spur a green energy transition.

Russia and Ukraine Accuse Each Other of Violating Energy Ceasefire

Russia-Ukraine Energy Ceasefire Violations escalate as U.S.-brokered truce frays, with drone strikes, shelling, and grid attacks disrupting gas supply and power infrastructure across Kursk, Luhansk, Sumy, and Dnipropetrovsk, prompting sanctions calls.

 

Key Points

Alleged breaches of a U.S.-brokered truce, with both sides striking power grids, gas lines, and critical energy nodes.

✅ Drone and artillery attacks reported on power and gas assets

✅ Both sides accuse each other of breaking truce terms

✅ U.S. mediation faces verification and compliance hurdles

 

Russia and Ukraine have traded fresh accusations regarding violations of a fragile energy ceasefire, brokered by the United States, which both sides had agreed to last month. These new allegations highlight the ongoing tensions between the two nations and the challenges involved in implementing a truce amid global energy instability in such a complex and volatile conflict.

The U.S.-brokered ceasefire had initially aimed to reduce the intensity of the fighting, specifically in the energy sector, where both sides had previously targeted each other’s infrastructure. Despite this agreement, the accusations on Wednesday suggest that both Russia and Ukraine have continued their attacks on each other's energy facilities, a crucial aspect of the ceasefire’s terms.

Russia’s Ministry of Defence claimed that Ukrainian forces had launched drone and shelling attacks in the western Kursk region, cutting power to over 1,500 homes. This attack allegedly targeted key infrastructure, leaving several localities without electricity. Additionally, in the Russian-controlled part of Ukraine's Luhansk region, a Ukrainian drone strike hit a gas distribution station, severely disrupting the gas supply for over 11,000 customers in the area around Svatove.

In response, Ukrainian President Volodymyr Zelensky accused Russia of breaking the ceasefire. He claimed that Russian drone strikes had targeted an energy substation in Ukraine’s Sumy region, while artillery fire had damaged a power line in the Dnipropetrovsk region, leaving nearly 4,000 consumers without power even as Ukraine increasingly leans on electricity imports to stabilize the grid. Ukraine's accusations painted a picture of continued Russian aggression against critical energy infrastructure, a strategy that had previously been a hallmark of Russia’s broader military operations in the war.

The U.S. had brokered the energy truce as a potential stepping stone toward a more comprehensive ceasefire agreement. However, the repeated violations raise questions about the truce’s viability and the broader prospects for peace between Russia and Ukraine. Both sides are accusing each other of undermining the agreement, which had already been delicate due to previous suspicions and mistrust. In particular, the U.S. administration, led by President Donald Trump, has expressed impatience with the slow progress in moving toward a lasting peace, amid debates over U.S. national energy security priorities.

Kremlin spokesperson Dmitry Peskov defended Russia’s stance, emphasizing that President Vladimir Putin had shown a commitment to peace by agreeing to the energy truce, despite what he termed as daily Ukrainian attacks on Russian infrastructure. He reiterated that Russia would continue to cooperate with the U.S., even though the Ukrainian strikes were ongoing. This perspective suggests that Russia remains committed to the truce but views Ukraine’s actions as violations that could potentially derail efforts to reach a more comprehensive ceasefire.

On the other hand, President Zelensky argued that Russia was not adhering to the terms of the ceasefire. He urged the U.S. to take a stronger stance against Russia, including increasing sanctions on Moscow as punishment for its violations. Zelensky’s call for heightened sanctions is a continuation of his efforts to pressure international actors, particularly the U.S. and European countries, to provide greater energy security support for Ukraine’s struggle and to hold Russia accountable for its actions.

The ceasefire’s fragility is also reflected in the differing views between Ukraine and Russia on what constitutes a successful resolution. Ukraine had proposed a full 30-day ceasefire, but President Putin declined, raising concerns about monitoring and verifying compliance with the terms. This disagreement suggests that both sides are not entirely aligned on what a peaceful resolution should look like and how it can be realistically achieved.

The situation is complicated by the broader context of the war, which has now dragged on for over three years. The conflict has seen significant casualties, immense destruction, and deep geopolitical ramifications. Both countries are heavily reliant on their energy infrastructures, making any attack on these systems not only a military tactic but also a form of economic warfare. Energy resources, including electricity and natural gas, have become central to the ongoing conflict, with both sides using them to exert pressure on the other amid Europe's deepening energy crisis that reverberates beyond the battlefield.

As of now, it remains unclear whether the recent violations of the energy ceasefire will lead to a breakdown of the truce or whether the United States will intervene further to restore compliance, even as Ukraine prepares for winter amid energy challenges. The situation remains fluid, and the international community continues to closely monitor the developments. The U.S., which played a central role in brokering the energy ceasefire, has made it clear that it expects both sides to uphold the terms of the agreement and work toward a more permanent cessation of hostilities.

The continued accusations between Russia and Ukraine regarding the breach of the energy ceasefire underscore the challenges of negotiating peace in such a complex and entrenched conflict. While both sides claim to be upholding their commitments, the reality on the ground suggests that reaching a full and lasting peace will require much more than temporary truces. The international community, particularly the U.S., will likely continue to push for stronger actions to enforce compliance and to prevent the conflict from further escalating. The outcome of this dispute will have significant implications for both countries and the broader European energy landscape and security landscape.

$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.
