AlbertaÂ’s electrical supply could face a crunch if the federal government insists on retiring coal-fired power plants that are 45 years old, says the head of Atco Electric.

Ottawa has yet to decide on whether it will allow the plants to operate for 45, 50 or 55 years. There is no scheme for plants to buy carbon offsets to extend their lives, so there will be a “hard shutdown” when the dates are reached.

That 10-year spread is crucial for Alberta, which is scrambling to ensure there will be sufficient low-cost electricity available.

“If they enact regulations with a 45-year limit, we will have to shut down Battle River units 3 and 4 in 48 months. That is 500 megawatts, and Alberta is already short because of the loss of TransAlta’s Sundance 1 and 2 units,” Nancy Southern said after the Canadian Utilities Ltd. annual general meeting.

“During the next 10 years, coal will be the lowest-cost power in the marketplace. To take that away from Albertans is something that any government has to really think about,” she said.

Atco chairman Ron Southern said nations such as Canada are too quick to discount coal.

“We are sitting on a fuel resource that everybody would bark like a fox for. It seems we are being a bit foolish because the costs of using the other kinds of energy are going to escalate.”

On a trip to Shanghai, he toured a plant that turns out 135 burner units a year for coal-fired plants, he said, and it is just one of three such plants in China. Countries like Australia are eagerly shipping coal to China, India, Thailand, Vietnam to burn in such plants.

“How else are the people going to get energy in these countries?”

To deal with the federal rules, Atco is considering a coal-gasification system to fire a power plant, something allowed under the federal legislation because emissions are as clean as natural gas.

“We have a lot of coal resources, and with Alberta’s deregulated power marketplace we are a beast of a different nature” than other provinces, she said, adding that by moving too quickly Alberta runs the risk of seeing electricity prices jump and harming the business climate.

Another strategy is to build new gas-fired plants that burn natural gas from an Atco field.

“We used to have an E&P exploration and production gas company. We are looking at doing that again, because the gas market has changed, and with prices where they are right now we have to look at capturing that as a bridging fuel.”

Hydro power from a low dam on the Athabasca River south of Fort McMurray is still being studied, and Atco still hopes to eventually build near SmithÂ’s Landing.

“We don’t see that hydro is dead, by any means.”

Atco is also planning to build a $1.6-billion eastern Alberta DC direct current transmission line between Fort Saskatchewan and Brooks down a right-of-way with few nearby residents.

“In order to get enough electricity, you are going to have to pull it from all different sources, renewable, co-generation, whatever the mix is going to be, and that allows you to keep it at a lower cost.”

Atco launched a new firm in January, Atco Australia, with its head office in Perth, to expand its existing gas-fired power plant business and get a slice of the booming pipeline, utilities and accommodation potential.

“Australia is really exciting with a lot of opportunities. It is wide open, much like Alberta was in the early 1970s,” she said.

“Karratha in Western Australia is near the huge natural gas deposits, and is just like Fort McMurray was, no housing, the need for power and utilities. And the temperature is very hot, almost the exact opposite of McMurray — plus 40 in Karratha and minus 40 here.

Romania moves to terminate talks with Chinese partner in nuke project

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

 

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

 

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.

Was there another reason for electricity shutdowns in California?

PG&E Wind Shutdown and Renewable Reliability examines PSPS strategy, wildfire risk, transmission line exposure, wind turbine cut-out speeds, grid stability, and California's energy mix amid historic high-wind events and supply constraints across service areas.

 

Key Points

An overview of PG&E's PSPS decisions, wildfire mitigation, and how wind cut-out limits influence grid reliability.

✅ Wind turbines reach cut-out near 55 mph, reducing generation.

✅ PSPS mitigates ignition from damaged transmission infrastructure.

✅ Baseload diversity improves resilience during high-wind events.

 

According to the official, widely reported story, Pacific Gas & Electric (PG&E) initiated power shutoffs across substantial portions of its electric transmission system in northern California as a precautionary measure.

Citing high wind speeds they described as “historic,” the utility claims that if it didn’t turn off the grid, wind-caused damage to its infrastructure could start more wildfires.

Perhaps that’s true. Perhaps. This tale presumes that the folks who designed and maintain PG&E’s transmission system are unaware of or ignored the need to design it to withstand severe weather events, and that the Federal Energy Regulatory Commission (FERC) and North American Electric Reliability Corp. (NERC) allowed the utility to do so.

Ignorance and incompetence happens, to be sure, but there’s much about this story that doesn’t smell right—and it’s disappointing that most journalists and elected officials are apparently accepting it without question.

Take, for example, this statement from a Fox News story about the Kincade Fires: “A PG&E meteorologist said it’s ‘likely that many trees will fall, branches will break,’ which could damage utility infrastructure and start a fire.”

Did you ever notice how utilities cut wide swaths of trees away when transmission lines pass through forests? There’s a reason for that: When trees fall and branches break, the grid can still function, and even as the electric rhythms of New York City shifted during COVID-19, operators planned for variability.

So, if badly designed and poorly maintained infrastructure isn’t the reason PG&E cut power to millions of Californians, what might have prompted them to do so? Could it be that PG&E’s heavy reliance on renewable energy means they don’t have the power to send when a “historic” weather event occurs, especially as policymakers weigh the postponed closure of three power plants elsewhere in California?

 

Wind Speed Limits

The two most popular forms of renewable energy come with operating limitations, which is why some energy leaders urge us to keep electricity options open when planning the grid. With solar power, the constraint is obvious: the availability of sunlight. One doesn’t generate solar power at night and energy generation drops off with increasing degrees of cloud cover during the day.

The main operating constraint of wind power is, of course, wind speed, and even in markets undergoing 'transformative change' in wind generation, operators adhere to these technical limits. At the low end of the scale, you need about a 6 or 7 miles-per-hour wind to get a turbine moving. This is called the “cut-in speed.” To generate maximum power, about a 30 mph wind is typically required. But, if the wind speed is too high, the wind turbine will shut down. This is called the “cut-out speed,” and it’s about 55 miles per hour for most modern wind turbines.

It may seem odd that wind turbines have a cut-out speed, but there’s a very good reason for it. Each wind turbine rotor is connected to an electric generator housed in the turbine nacelle. The connection is made through a gearbox that is sized to turn the generator at the precise speed required to produce 60 Hertz AC power.

The blades of the wind turbine are airfoils, just like the wings of an airplane. Adjusting the pitch (angle) of the blades allows the rotor to maintain constant speed, which, in turn, allows the generator to maintain the constant speed it needs to safely deliver power to the grid. However, there’s a limit to blade pitch adjustment. When the wind is blowing so hard that pitch adjustment is no longer possible, the turbine shuts down. That’s the cut-out speed.

Now consider how California’s power generation profile has changed. According to Energy Information Administration data, the state generated 74.3 percent of its electricity from traditional sources—fossil fuels and nuclear, amid debates over whether to classify nuclear as renewable—in 2001. Hydroelectric, geothermal, and biomass-generated power accounted for most of the remaining 25.7 percent, with wind and solar providing only 1.98 percent of the total.

By 2018, the state’s renewable portfolio had jumped to 43.8 percent of total generation, with clean power increasing and wind and solar now accounting for 17.9 percent of total generation. That’s a lot of power to depend on from inherently unreliable sources. Thus, it wouldn’t be at all surprising to learn that PG&E didn’t stop delivering power out of fear of starting fires, but because it knew it wouldn’t have power to deliver once high winds shut down all those wind turbines

'For now, we're not touching it': Quebec closes door on nuclear power

Quebec Energy Strategy focuses on hydropower, energy efficiency, and new dams as Hydro-Que9bec pursues Churchill Falls deals and the Champlain Hudson Power Express to New York, while nuclear power remains off the agenda.

 

Key Points

Quebec's plan prioritizes hydropower, efficiency, and new dams, excludes nuclear, and expands exports via CHPE.

✅ Nuclear power shelved; focus on renewables and dams

✅ Hydro-Que9bec pursues Churchill Falls and Gull Island talks

✅ CHPE line to New York advances; export contract with NYSERDA

 

Quebec Premier François Legault has closed the door on nuclear power, at least for now.

"For the time being, we're not touching it," said Legault when asked about the subject at a press scrum in New York on Tuesday.

The government is looking for new sources of energy as Hydro-Québec begins talks on a $185-billion strategy to wean the province off fossil fuels. In an interview with The Canadian Press at Quebec's official residence in New York, Legault said there are a number of avenues to explore:

  • Energy efficiency.
  • Negotiations with Newfoundland and Labrador over Churchill Falls and Gull Island.
  • Upgrading existing dams and building new ones.

"Nuclear power is not on the agenda," he said.

Yet the premier seemed open to the nuclear question some time ago. In August, Radio-Canada reported that he had raised the idea of nuclear power in front of dozens of MNAs at the National Assembly last April.

Also in August, Hydro-Québec was evaluating the possibility of reopening the Gentilly-2 nuclear power plant, which has been closed since 2012.

Asked about his leader's statement on Tuesday, the Minister of the Economy, Pierre Fitzgibbon, maintained his line: "At the moment, we're looking at everything that's possible because we know that we have a significant deficit in the supply of green energy," he said.

Another step forward for the Quebec-New York line

Premier Legault took part in Tuesday morning's announcement that construction had begun on the New York converter station of the Champlain Hudson Power Express line. New York State Governor Kathy Hochul was present at the announcement.

In November 2021, Hydro-Québec signed a contract with the New York State Energy Research and Development Authority (NYSERDA) to export 10.4 terawatt-hours of electricity to the American metropolis over 25 years, while Ontario declined to renew a deal with Quebec.

At a time when the Quebec government is constantly asserting that more energy will be needed for future economic projects -- particularly the battery industry -- Legault sees no contradiction in selling electricity to the Americans and to neighboring provinces such as NB Power deals to import Hydro-Québec power.

"Whether it's this contract or the contract for companies coming to set up in Quebec, it's out of the surplus we currently have in Quebec. Now, we have dozens of investment project proposals in Quebec where we need additional electricity," he explained.

The line will supply 20 per cent of New York City's electricity needs, despite transmission constraints on Quebec-to-U.S. deliveries. Commissioning is scheduled for May 2026. The spin-offs are estimated at $30 billion, according to the premier.

Will this money be used to finance new dams, such as the La Romaine hydroelectric complex built in recent years?

"It's certain that future projects will cost several tens of billions of dollars. Hydro-Québec has the capacity to borrow. It's a very healthy company. There's no doubt that these revenues will improve Hydro-Québec's image," he said.

City officials take clean energy message to Georgia Power, PSC

Georgia Cities Clean Energy IRP Coalition unites Savannah, Atlanta, Decatur, and Athens-Clarke to shape Georgia Power's Integrated Resource Plan, accelerating renewables, energy efficiency, community solar, and coal retirements through Georgia Public Service Commission hearings.

 

Key Points

Georgia cities working to steer Georgia Power's IRP toward renewables, energy efficiency, and community solar.

✅ Targets coal retirements and doubling renewables by 2035

✅ Advocates data access, transparency, and energy efficiency

✅ Seeks affordable community solar options for low-income customers

 

Savannah is among several Georgia cities that have led the charge forward in recent years to push for clean energy. Now, several of the state's largest municipalities are banding together to demand action from Georgia's largest energy provider.

Hearings regarding Georgia Power's Integrated Resource Plan (IRP) happen every three years, but this year for the first time the cities of Savannah, Decatur, Atlanta and Athens-Clarke and DeKalb counties were at the table.

"It's pretty unprecedented. It's such an important opportunity to get to represent ourselves and our citizens," said City of Savannah Energy Analyst Alicia Brown, the Savannah representative for the Georgia Coalition for Local Governments.

The IRP, which essentially maps out how the company will use its various forms of energy over the next 20 years was filed with the Georgia Public Service Commission (GPSC) in January, the 200-page IRP outlines Georgia Power's plans to shutter nearly all Georgia Power-controlled coal units, similar to Tucson Electric Power's coal exit timelines elsewhere, which could begin later this year.

The company is also planning to double its renewable energy generation by 2035. The IRP also outlines plans for several programs, including an Income-Qualified Community Solar Pilot, reflecting momentum for community energy programs in other states as well.

During the hearings the coalition, alongside the other groups, had the ability to question Georgia Power officials about the plan to include the proposed increase per kilowatt for the company's Simple Solar program, Behind-the-Meter Solar program study and various other components, amid debates over solar strategy in the South that could impact lower income customers.

"The established and open IRP process is central to effective, long-term energy planning in Georgia and is part of our commitment to 2.7 million customers to deliver clean, safe, reliable and affordable energy. In continuing our longstanding relationship with the City of Savannah, we welcome their interest and participation in the IRP process," John Kraft, Georgia Power spokesman said in an email.

Brown said the coalition's areas of interest fall into three categories: energy efficiency and demand response, data access and transparency and renewable energy for citizens as well as the governments in the coalition.

"We have these renewable goals and just the way the current regulations are set, the way the current laws are on the books, and developments like consumer choice in California show how policy shifts can reshape utility markets, it's very challenging for us to meet those renewable energy goals without Georgia Power setting up programs that are workable for us," she said.

The city of Savannah is already taking action locally to reduce carbon emissions and move toward clean and renewable energy through the 100% Savannah Clean Energy Plan, which was adopted by Savannah City Council in December.

The plan aims to achieve 100% renewable electricity community-wide by 2035 and 100% renewable energy for all energy needs by 2050.

Council previously approved the 100% Clean Energy Resolution needed to develop the plan in March 2020, making Savannah the fifth city in the state to pledge to pursue a lower carbon future to fight climate change.

The final plan includes 45 strategies that fall into five categories: energy efficiency; renewable energy; transportation and mobility; community and economic development; and education and engagement.

Brown said the education and engagement component is central to the plan, but the pandemic has hindered community education and awareness efforts, and utilities have warned customers about pandemic-related scams that complicate outreach, something the city hopes to catapult in the coming weeks.

"With the 100% Savannah resolution passing right before the pandemic, we haven't had as many opportunities to raise awareness about the initiative and to educate the public about clean energy as we would like. This transition will present a lot of opportunities for our communities, but only if people know that they are there to be taken," she said.

"... We also want to engage the community so that they feel like they are developing this vision for a healthy, prosperous, clean community alongside us. It's not just us telling them, 'we're going to have a clean energy future and it's going to look like this,' but really helping them to develop and realize a collective vision for what 100% Savannah should be."

The final round of IRP hearings are scheduled for next month. Those hearings will allow the coalition and other groups to put witnesses on the stand who will make the case for why Georgia Power's IRP should be different, Brown said.

In June, Georgia Power, following a June bill reduction for customers, will have a chance to offer rebuttal testimony and will again be subject to cross examination. Shortly after those hearings, the parties will join together for the settlement process, a sort of compromise on the plan that the commission will vote on toward the beginning of July.

Seven small UK energy suppliers must pay renewables fees or risk losing licence

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

 

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

 

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

California's solar energy gains go up in wildfire smoke

California Wildfire Smoke Impact on Solar reduces photovoltaic output, as particulate pollution, soot, and haze dim sunlight and foul panels, cutting utility-scale generation and grid reliability across CAISO during peak demand and heatwaves.

 

Key Points

How smoke and soot cut solar irradiance and foul panels, slashing PV generation and straining CAISO grid operations.

✅ Smoke blocks sunlight; soot deposition reduces panel efficiency.

✅ CAISO reported ~30% drop versus July during peak smoke.

✅ Longer fire seasons threaten solar reliability and capacity planning.

 

Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state, even as U.S. solar generation rose in 2022 nationwide. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.

Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California Independent System Operator (CAISO), which oversees nearly all utility-scale solar energy in California, where wind and solar curtailments have been rising amid grid constraints. It was a 13.4 percent decrease from the same period last year, even though solar capacity in the state has grown about 5 percent since September 2019.

California depends on solar installations for nearly 20 percent of its electricity generation, and has more solar capacity than the next five US states trailing it combined as it works to manage its solar boom sustainably. It will need even more renewable power to meet its goal of 100 percent clean electricity generation by 2045, building on a recent near-100% renewable milestone that underscored the transition. The state’s emphasis on solar power is part of its long-term efforts to avoid more devastating effects of climate change. But in the short term, California’s renewables are already grappling with rising temperatures.

Two records were smashed early this September that contributed to the loss of solar power. California surpassed 2 million acres burned in a single fire season for the first time (1.7 million more acres have burned since then). And on September 15th, small particle pollution reached the highest levels recorded since 2000, according to the California Air Resources Board. Winds that stoked the flames also drove pollution from the largest fires in Northern California to Southern California, where there are more solar farms.

Smaller residential and commercial solar systems were affected, too, and solar panels during grid blackouts typically shut off for safety, although smoke was the primary issue here. “A lot of my systems were producing zero power,” Steve Pariani, founder of the solar installation company Solar Pro Energy Systems, told the San Mateo Daily Journal in September.

As the planet heats up, California’s fire seasons have grown longer, and blazes are tearing through more land than ever before, while grid operators are also seeing rising curtailments as they integrate more renewables. For both utilities and smaller solar efforts, wildfire smoke will continue to darken solar energy’s otherwise bright future, even as it becomes the No. 3 renewable source in the U.S. by generation.
