TVA will install new air pollution control equipment to three coal-burning power plants in East Tennessee, as it has previously pledged, TVAÂ’s president and CEO told a federal court recently.

A climate of tightening regulations, and the fact that TVA has already begun the upgrades, dictates finishing the upgrades, chief executive officer Tom Kilgore said.

“We’ve invested about a billion dollars… in East Tennessee,” Kilgore said. “It would be foolhardy not to complete those.”

TVA rested its case after KilgoreÂ’s testimony in federal court, where the state of North Carolina is suing to force the public electricity producer to reduce emissions by 2013. ThatÂ’s the deadline required of utilities within its borders.

Under cross-examination, Kilgore conceded that in the past TVA had made significant financial investments on plans it later abandoned, specifically the construction of a series of nuclear plants. The agency spent years building several that were later cancelled, leaving the agency deep in debt. Its debt is about $25 billion today.

TVA more recently announced it would put “scrubbers” on its Colbert coal-fired plant in Alabama to lessen emissions there, and later switched its plans. Kilgore said the agency intends to put them on its John Sevier plant in East Tennessee instead.

TVA, the nationÂ’s largest public power producer, provides electricity to distributors throughout Tennessee and parts of six other states. Most comes from burning coal, with the second-largest amount from nuclear power.

North Carolina contends that air emissions from TVAÂ’s coal-burning plants are moving over the southern Appalachian Mountains and causing problems in that state that include cardio-vascular and respiratory illnesses and deaths.

Marc Bernstein, with the North Carolina attorney generalÂ’s office, questioned whether TVA would really take action without a law hanging over it. He also discussed the years 1983-93, when money was not spent on air pollution control equipment.

Since the U.S. Environmental Protection AgencyÂ’s Clean Air Interstate Rule was shot down in federal court this month, the agency has little reason to follow through with its current plans for reductions, the stateÂ’s suit argues.

“It does not change what we’re going to do to clean up the air,” Kilgore insisted in court.

Earlier in the day, a top Tennessee air pollution chief chastised North Carolina for emissions at power plants within its own borders and defended TVA as a model operator of plants in Tennessee.

Quincy Styke, deputy director for Tennessee Division of Air Pollution Control, said TVAÂ’s operations are all properly permitted and he has no doubt that the agency will complete its plans.

He reacted with vigor when asked about North CarolinaÂ’s enactment of its Clean Smokestacks Act of 2002, which is requiring utilities in that state by 2013 to cap emissions of haze-, acid- and particle-producing sulfur dioxide and ozone-forming nitrogen oxide.

That stateÂ’s sulfur dioxide emissions rose to a high in 2005, Styke said.

“Tennessee has not enacted similar legislation because it’s not necessary,” he said.

“We follow all the federal rule.… We don’t need a statute. Tennessee has been about the business of controlling its emissions.”

North Carolina officials have said that emissions have been dropping significantly as private investor-owned utilities in the state phase in equipment as the deadline approaches.

Most of TVAÂ’s plants and employees are in Tennessee, though there are two plants in Alabama and two plants in Kentucky.

Witnesses on both TVAÂ’s and North CarolinaÂ’s side have testified that reductions of the agencyÂ’s emissions would benefit Tennesseans more, because more of its pollution affects Tennessee.

NB Power signs three deals to bring more Quebec electricity into the province

NB Power and Hydro-Québec Electricity Agreements expand clean hydroelectric exports, support Mactaquac dam refurbishment, add grid interconnections, and advance decarbonization, climate goals, reliability, and transmission capacity across Atlantic Canada and U.S. markets through 2040.

 

Key Points

Deals for hydro exports, Mactaquac upgrades, and new interconnections to improve reliability and cut emissions.

✅ 47 TWh to NB by 2040 over existing transmission lines

✅ HQ expertise to address Mactaquac concrete swelling

✅ Talks on new interconnections for Atlantic and U.S. exports

 

NB Power and Hydro-Quebec have signed three deals that will see Quebec sell more electricity to New Brunswick and provide help with the refurbishment of the Mactaquac hydroelectric generating station.

Under the first agreement, Hydro-Quebec will export 47 terawatt hours of electricity to New Brunswick between now and 2040 over existing power lines — expanding on an agreement in place since 2012 and on related regional agreements such as the Churchill Falls deal in Newfoundland and Labrador.

The second deal will see Hydro-Quebec share expertise for part of the refurbishment of the Mactaquac dam to extend the useful life of the generating station until at least 2068, when the 670 megawatt facility on the St. John River will be 100 years old.

Since the 1980s, concrete portions of the facility have been affected by a chemical reaction that causes the concrete to swell and crack.

Hydro-Quebec has been dealing with the same problem, and has developed expertise in addressing the issue.

“This is why we have signed a technical collaboration agreement between Hydro-Quebec and us for part of the refurbishment of the Mactaquac generating station,” NB Power president Gaetan Thomas said Friday.

Eric Martel, CEO of Hydro-Quebec, said hydroelectric plants provide long-term clean power that’s important in the fight against climate change as the province has ruled out nuclear power for now.

“We understand how important it is to ensure the long term sustainability of these facilities and we are happy to share the expertise that Hydro-Quebec has acquired over the years,” Martel said.

The refurbishment of the Mactaquac generating station is expected to cost between $2.9 billion and $3.5 billion. Once the work begins, each of the facility’s six generators will have to be taken offline for months at a time, and Thomas said that’s where the increased power from Quebec, supported by Hydro-Quebec's capacity expansion in recent years, will come into use.

He expects the power could cost about $100 million per year but will be much cheaper than other sources.

The third agreement calls for talks to begin for the construction of additional power connections between Quebec and New Brunswick to increase exports to Atlantic Canada and the United States, where transmission constraints have limited incremental deliveries in recent years.

“Building new interconnections and allowing for increased power transfer between our systems could be mutually beneficial, even as historic tensions in Newfoundland and Labrador linger. More than ever, we are looking to the future,” Martel said.

“Partnering will permit us to seize new business opportunities together and pool our effort to support de-carbonization, including Hydro-Quebec's non-fossil strategy that is now underway, and fight against climate change, both here and in our neighbourhood market,” he said.

US NRC streamlines licensing for advanced reactors

NRC Advanced Reactor Licensing streamlines a risk-informed, performance-based, technology-inclusive pathway for advanced non-light water reactors, aligning with NEIMA to enable predictable regulatory reviews, inherent safety, clean energy deployment, and industrial heat, hydrogen, and desalination applications.

 

Key Points

A risk-informed, performance-based NRC pathway streamlining licensing for advanced non-light water reactors.

✅ Aligned with NEIMA: risk-informed, performance-based, tech-inclusive

✅ Predictable licensing for advanced non-light water reactor designs

✅ Enables clean heat, hydrogen, desalination beyond electricity

 

The US Nuclear Regulatory Commission (NRC) voted 4-0 to approve the implementation of a more streamlined and predictable licensing pathway for advanced non-light water reactors, aligning with nuclear innovation priorities identified by industry advocates, the Nuclear Energy Institute (NEI) announced, and amid regional reliability measures such as New England emergency fuel stock plans that have drawn cost scrutiny.

This approach is consistent with the Nuclear Energy Innovation and Modernisation Act (NEIMA), a nuclear innovation act passed in 2019 by the US Congress calling for the development of a risk-informed, performance-based and technology inclusive licensing process for advanced reactor developers.

NEI Chief Nuclear Officer Doug True said: “A modernised regulatory framework is a key enabler of next-generation nuclear technologies that, amid ACORE’s challenge to DOE subsidy proposals in energy market proceedings, can help us meet our energy needs while protecting the climate. The Commission’s unanimous approval of a risk-informed and performance-based licensing framework paves the way for regulatory reviews to be aligned with the inherent safety characteristics, smaller reactor cores and simplified designs of advanced reactors.”

Over the last several years the industry’s Licensing Modernisation Project, sponsored by US Department of Energy, led by Southern Nuclear, and supported by NEI’s Advanced Reactor Regulatory Task Force, and influenced by a presidential order to bolster uranium and nuclear energy, developed the guidance for this new framework. Amid shifts in the fuel supply chain, including the U.S. ban on Russian uranium, this approach will inform the development of a new rule for licensing advanced reactors, which NEIMA requires.

“A well-defined licensing path will benefit the next generation of nuclear plants, especially as regions consider New England market overhaul efforts, which could meet a wide range of applications beyond generating electricity such as producing heat for industry, desalinating water, and making hydrogen – all without carbon emissions,” True noted.

94,000 lose electricity in LA area after fire at station

Los Angeles Power Station Fire prompts LADWP to shut a Northridge/Reseda substation, causing a San Fernando Valley outage amid a heatwave; high-voltage equipment and mineral oil burned as 94,000 customers lost power, elevator rescues reported.

 

Key Points

An LADWP substation fire in Northridge/Reseda caused a major outage; 94,000 customers affected as crews restore power.

✅ Fire started around 6:52 p.m.; fully extinguished by 9 p.m.

✅ High-voltage gear and mineral oil burned; no injuries reported.

✅ Outages hit Porter Ranch, Reseda, West Hills, Granada Hills.

 

About 94,000 customers were without electricity Saturday night after the Los Angeles Department of Water and Power shut down a power station in the northeast San Fernando Valley that caught fire, the agency said.

The fire at the station in the Northridge/Reseda area of Los Angeles started about 6:52 p.m. and involved equipment that carries high-voltage electricity and distributes it at lower voltages to customers in the surrounding area, the department said, even as other utilities sometimes deploy wildfire safety shut-offs to reduce risk during dangerous conditions.

The department shut off power to the station as a precautionary move, and it is restoring power now that the fire has been put out, similar to restoration after intentional shut-offs in other parts of California. Initially, 140,000 customers were without power. That number had been cut to 94,000 by 11 p.m.

The power outage comes as much of California baked in heat that broke records, and rolling blackout warnings were issued as the grid strained. A record that stood 131 years in Los Angeles was snapped when the temperature spiked at 98 degrees downtown.

People reported losing power in Porter Ranch, Winnetka, West Hills, Canoga Park, Woodland Hills, Granada Hills, North Hills, Reseda and Chatsworth, KABC TV reported, highlighting electricity inequality across communities.

Shortly after the blaze broke out, firefighters found a huge container of mineral oil that is used to cool electrical equipment on fire, Los Angeles Fire Department spokesman Brian Humphrey told the Los Angeles Times. The incident underscores infrastructure risks that in some regions have required a complete grid rebuild after severe storms.

Firefighters had the blaze under control by 8:30 p.m. and were able to put it out by 9 p.m., Humphrey said. "These were fierce flames, with smoke towering more than 300 feet into the sky," he told the newspaper.

No one was injured.

Firefighters rescued people who were stranded in elevators, Humphrey said.

Survivors of deadly tornadoes may go weeks without heat, water, electricity, Kentucky officials say

Kentucky Tornado Recovery details Mayfield damage, death toll, power outages, boil-water advisories, shelter operations, and emergency response across five states, as crews restore infrastructure, locate missing persons, and support displaced families in frigid temperatures.

 

Key Points

Overview of restoring utilities, repairing infrastructure, and sheltering survivors after Kentucky's tornado disaster.

✅ Power, water, and gas outages persist; boil-water advisories in effect.

✅ Mayfield hardest hit; factory casualties lower than first feared.

✅ Shelter provided in state park lodges; long-term recovery expected.

 

Residents of Kentucky counties where tornadoes killed several dozen people could be without heat, water or electricity in frigid temperatures for weeks or longer, state officials warned Monday, and experiences abroad like Kyiv's difficult winter underscore the risks as the toll of damage and deaths came into clearer focus in five states slammed by the swarm of twisters.

Authorities are still tallying the devastation from Friday's storms, though they believe the death toll will be lower than initially feared since it appeared many more people escaped a candle factory in Mayfield, Ky., than first thought.

At least 88 people — including 74 in Kentucky — were killed by the tornados which also destroyed a nursing home in Arkansas, heavily damaged an Amazon distribution centre in Illinois and spread their deadly effects into Tennessee and Missouri, while ongoing nuclear worker safety concerns highlighted vulnerabilities across critical facilities. Another 105 people were still unaccounted for in Kentucky as of Monday afternoon, Gov. Andy Beshear said.

As searches continued for those still missing, efforts also turned to repairing the power grid, downed line safety education, sheltering those whose homes were destroyed and delivering drinking water and other supplies.

"We're not going to let any of our families go homeless," Beshear said in announcing that lodges in state parks were being used to provide shelter.

In Bowling Green, Ky., 11 people died on the same street, including two infants found among the bodies of five relatives near a residence, Warren County coroner Kevin Kirby said. 

In Mayfield, one of the hardest hit towns, those who survived faced a high around 10 C and a low below freezing Monday without any utilities, and awareness of power strip fire risks is critical as residents turn to makeshift heating and power.

"Our infrastructure is so damaged. We have no running water. Our water tower was lost. Our waste water management was lost, and there's no natural gas to the city. So we have nothing to rely on there," Mayfield Mayor Kathy Stewart O'Nan said on CBS Mornings. "So that is purely survival at this point for so many of our people."

Across the state, about 26,000 homes and businesses were without electricity, according to poweroutage.us, including nearly all of those in Mayfield, and the U.S. grid warning during the pandemic underscored vulnerabilities in critical infrastructure.

More than 10,000 homes and businesses have no water, and another 17,000 are under boil-water advisories, Kentucky Emergency Management Director Michael Dossett told reporters.

Dossett warned that full recovery in the hardest-hit places could take not just months, but years, noting that utilities have at times contemplated on-site staffing to maintain operations during crises.

At least 74 people have been confirmed dead across Kentucky after tornadoes tore through the state, leaving some communities nearly totally destroyed and many residents wondering if they can afford to rebuild. 2:22
"This will go on for years to come," he said. 

Amid broader economic strain, recent debates over Kentucky miners' pay highlight ongoing financial vulnerabilities for workers affected by disasters as well.

Authorities are still trying to determine the total number of dead, and the storms made door-to-door searches impossible in some places. "There are no doors," said Beshear.

"We're going to have over 1,000 homes that are gone, just gone," he said.

Beshear had said Sunday morning that the state's toll could exceed 100. But he later said it might be as low as 50.

'Then he was gone'
Initially as many as 70 people were feared dead in the candle factory in Mayfield, but the company said Sunday that eight were confirmed dead and eight remained missing, while more than 90 others had been located.

"Many of the employees were gathered in the tornado shelter and after the storm was over they left the plant and went to their homes," said Bob Ferguson, a spokesman for the company. "With the power out and no landline they were hard to reach initially. We're hoping to find more of those eight unaccounted as we try their home residences."

UK Emergency energy plan not going ahead

National Grid Demand Flexibility Service helps stabilise the UK grid during tight supply, offering discounts for smart meter users who shift peak-time electricity use, reducing power cut risks amid low wind and import constraints.

 

Key Points

A National Grid scheme paying smart homes to cut peak-time use, easing supply pressure and avoiding power cuts.

✅ Pays volunteers with smart meters to reduce peak demand.

✅ Credits discounts for shifting use to off-peak windows.

✅ Manages tight margins and helps avert UK power cuts.

 

National Grid has decided not to activate a scheme on Tuesday to help the UK avoid power cuts after being poised to do so.

It would have seen some households offered discounts on their electricity bills if they cut peak-time use.

National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.

However, it decided that the measure was not required.

Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.

National Grid said it was "confident" it would be able to manage margins and "demand is not at risk".

Discounts
Earlier on Monday, the grid operator said it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.

Under the Demand Flexibility Service (DFS), announced earlier this month, customers that have signed up could get discounts on their bills if they use less electricity in a given window of time.

That could mean delaying the use of a tumble-dryer or washing machine, or cooking dinner in the microwave rather than the oven.

Major suppliers such as Octopus and British Gas are taking part, but only customers that have an electricity smart meter and that have volunteered are eligible. About 14 million UK homes have an electricity smart meter.

The DFS has already been tested twice but has not yet run live.

Octopus, the supplier with the most customers signed up, said that some households had earned more than £4 during the hour-long tests, while the average saving was "well over £1".

It came after forecasts projected a large drop in the amount of power that Britain will be able to import from French nuclear power stations on Monday and Tuesday evenings.

The lack of strong winds to power turbines has also affected how much power can be generated within the UK, and efforts to fast-track grid connections aim to ease constraints.

Such warnings are not unusual - around 12 have been issued and cancelled without issue in the last six years, and other regions such as Canada are seeing grids strained by harsh weather as well.

However, they have become more common this year due to the energy crisis, and the most recent notice was sent out last week.

The situation means that the UK will have to import electricity from other sources on Monday and Tuesday evening.

Supplies are also expected be tight in France, forecasters say.

France has been facing months of problems with its nuclear power plants, which generate around three-quarters of the country's electricity.

More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.

It has added to a massive energy crisis in Europe which is facing a winter without gas supplies from Russia.

Duke Energy will spend US$25bn to modernise its US grid

Duke Energy Clean Energy Strategy targets smart grid upgrades, wind and solar expansion, efficient gas, and high-reliability nuclear, cutting CO2, boosting decarbonization, and advancing energy efficiency and reliability for the Carolinas.

 

Key Points

A plan investing in smart grids, renewables, gas, and nuclear to cut CO2 and enhance reliability and efficiency by 2030.

✅ US$25bn smart grid upgrades; US$11bn renewables and gas

✅ 40% CO2 reduction and >80% low-/zero-carbon generation by 2030

✅ 2017 nuclear fleet 95.64% capacity factor; ~90 TWh carbon-free

 

The US power group Duke Energy plans to invest US$25bn on grid modernization over the 2017-2026 period, including the implementation of smart grid technologies to cope with the development of renewable energies, along with US$11bn on the expansion of renewable (wind and solar) and gas-fired power generation capacities.

The company will modernize its fleet and expects more than 80% of its power generation mix to come from zero and lower CO2 emitting sources, aligning with nuclear and net-zero goals, by 2030. Its current strategy focuses on cutting down CO2 emissions by 40% by 2030. Duke Energy will also promote energy efficiency and expects cumulative energy savings - based on the expansion of existing programmes - to grow to 22 TWh by 2030, i.e. the equivalent to the annual usage of 1.8 million households.

Duke Energy’s 11 nuclear generating units posted strong operating performance in 2017, as U.S. nuclear costs hit a ten-year low, providing the Carolinas with nearly 90 billion kilowatt-hours of carbon-free electricity – enough to power more than 7 million homes.

Globally, China's nuclear program remains on a steady development track, underscoring broader industry momentum.

“Much of our 2017 success is due to our focus on safety and work efficiencies identified by our nuclear employees, along with ongoing emphasis on planning and executing refueling outages to increase our fleet’s availability for producing electricity,” said Preston Gillespie, Duke Energy chief nuclear officer.

Some of the nuclear fleet’s 2017 accomplishments include, as a new U.S. reactor comes online nationally:

  • The 11 units achieved a combined capacity factor of 95.64 percent, second only to the fleet’s 2016 record of 95.72 percent, marking the 19th consecutive year of attaining a 90-plus percent capacity factor (a measure of reliability).
  • The two units at Catawba Nuclear Station produced more than 19 billion kilowatt-hours of electricity, and the single unit at Harris Nuclear Plant generated more than 8 billion kilowatt-hours, both setting 12-month records.
  • Brunswick Nuclear Plant unit 2 achieved a record operating run.
  • Both McGuire Nuclear Station units completed their shortest refueling outages ever and unit 1 recorded its longest operating run.
  • Oconee Nuclear Station unit 2 achieved a fleet record operating run.

The Robinson Nuclear Plant team completed the station’s 30th refueling outage, which included a main generator stator replacement and other life-extension activities, well ahead of schedule.

“Our nuclear employees are committed to providing reliable, clean electricity every day for our Carolinas customers,” added Gillespie. “We are very proud of our team’s 2017 accomplishments and continue to look for additional opportunities to further enhance operations.”
