AECL agrees on nuclear study in China

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

GE Wind Turbine Collapse Brazil raises safety concerns at Omega Energia's Delta VI wind farm in Maranhe3o, with GE Renewable Energy probing root-cause of turbine failure after a worker injury and similar incidents in 2024.

Key Points

An SEO focus on the Brazil GE turbine collapse, its causes, safety investigation, and related 2024 incidents.

✅ Incident at Omega Energia's Delta VI, Maranhao; one worker injured

✅ GE Renewable Energy conducts root-cause investigation and containment

✅ Fifth GE turbine collapse in 2024 across Brazil and the United States

A GE Renewable Energy turbine collapsed at a wind farm in north-east Brazil, injuring a worker and sparking a probe into the fifth such incident this year, the manufacturer confirmed.

One of the manufacturer’s GE 2.72-116 turbines collapsed at Omega Energia’s Delta VI project in Maranhão, which was commissioned in 2018.

Three GE employees were on site at the time of the collapse on Tuesday (3 September), the US manufacturer confirmed, even as U.S. offshore wind developers signal growing competitiveness with gas. 

One worker was injured and is currently receiving medical treatment, GE added.

"We are working to determine the root cause of this incident and to provide proper support as needed," it said

The turbine collapse in Brazil is the fifth such incident involving GE turbines this year, even as the UK's biggest offshore windfarm begins power supply this week, underscoring broader sector momentum.

On 16 February, a turbine collapsed at NextEra Energy Resources’ Casa Mesa wind farm in New Mexico, US, while giant wind components were being transported to a project in Saskatchewan, Canada. The site uses GE’s 2.3-116 and 2.5-127 models.

The New Mexico incident was followed by another collapse in the US — as a Scottish North Sea wind farm resumed construction after Covid-19 — this time a GE 2.4-107 unit at Tradewind Energy’s Chisholm View 2 project in Oklahoma on 21 May.

Two GE turbines then collapsed at projects in July: a 2.5-116 unit at Invenergy’s Upstreamwind farm in Nebraska on 5 July, followed by a 1.7-103 model at the Actis Group-owned Ventos de São Clemente complex in Pernambuco, north-eastern Brazil, even as tidal power in Scotland generated enough electricity to power nearly 4,000 homes.

No employees were injured in the first four turbine collapses of the year, in contrast with concerns at a Hawaii geothermal plant over potential meltdown risk.

In response to the latest incident, GE Renewable Energy added: "It is too early to speculate about the root cause of this week’s turbine collapse.

"Based on our learnings from the previous turbine collapses, we have teams in place focused on containing and resolving these issues quickly, to ensure the safe and reliable operation of our turbines."

Portsmouth Wind Turbine Complaints highlight noise, shadow flicker, resident impacts, Town Council hearings, and Green Development mitigation plans near Portsmouth High School, covering renewable energy output, PPAs, and community compliance.

Key Points

Resident reports of noise and shadow flicker near Portsmouth High School, prompting review and mitigation efforts.

✅ Noise exceeds ambient levels seasonally, residents report fatigue.

✅ Shadow flicker lasts up to 90 minutes on affected homes.

✅ Town tasks developer to meet neighbors and propose mitigation.

The combination of the noise and shadows generated by the town’s wind turbine has rankled some neighbors who voiced their frustration to the Town Council during its meeting Monday.

Mark DePasquale, the founder and chairman of the company that owns the turbine, tried to reassure them with promises to address the bothersome conditions.

David Souza, a lifelong town resident who lives on Lowell Drive, showed videos of the repeated, flashing shadows cast on his home by the three blades spinning.

“I am a firefighter. I need to get my sleep,” he said. “And now it’s starting to affect my job. I’m tired.”

Town Council President Keith Hamilton tasked DePasquale with meeting with the neighbors and returning with an update in a month. “What I do need you to do, Mr. DePasquale, is to follow through with all these people.”

DePasquale said he was unaware of the flurry of complaints lodged by the residents Monday. His company had only heard of one complaint. “If I knew there was an issue before tonight, we would have responded,” he said.

His company, Green Development LLC, formerly Wind Energy Development LLC, installed the 279-foot-tall turbine near Portsmouth High School that started running in August 2016, as offshore developers like Deepwater Wind in Massachusetts plan major construction nearby. It replaced another turbine installed by a separate company that broke down in 2012.

In November 2014, the town signed an agreement with Wind Energy Development to take down the existing turbine, pay off the remaining $1.45 million of the bond the town took out to install it and put up a new turbine, amid broader legal debates like the Cornwall wind farm ruling that can affect project timelines.

In exchange, Wind Energy Development sells a portion of the energy generated by the turbine to the town at a rate of 15.5 cents per kilowatt hour for 25 years. Some of the energy generated is sold to the town of Coventry.

“We took down (the old turbine) and paid off the debt,” DePasquale said, noting that cancellations can carry high costs as seen in Ontario wind project penalties for scrapping projects. “I have no problem doing whatever the council wants … There was an economic decision made to pay off the bond and build something better.”

The turbine was on pace to produce 4 million-plus kilowatt hours per year, Michelle Carpenter, the chief operating officer of Wind Energy Development, said last April. It generates enough energy to power all municipal and school buildings in town, she said, while places like Summerside’s wind power show similarly strong output.

The constant stream of shadows cast on certain homes in the area can last for as long as an hour-and-a-half, according to Souza. “We shouldn’t have to put up with this,” he said.

Sprague Street resident John Vegas said the turbine’s noise, especially in late August, is louder than the neighborhood’s ambient noise.

“Throughout the summer, there’s almost no flicker, but this time of year it’s very prominent,” Vegas added. “It can be every day.”

He mentioned neighbors needed to be better organized to get results.

“When the residents purchased our properties we did not have this wind turbine in our backyard,” Souza said in a memo. “Due to the wind turbine … our quality of life has suffered.”

After the discussion, the council unanimously voted to allow Green Development to sublease excess energy to the Rhode Island Convention Center Authority, a similar agreement to the one the company struck with Coventry, as regional New England solar growth adds pressure on grid upgrade planning.

“This has to be a sustainable solution,” DePasquale said. “We will work together with the town on a solution.”

Hydro-Que9bec 2020 Profit Outlook faces COVID-19 headwinds as revenue drops, U.S. Northeast export demand weakens, and clean-energy infrastructure plans shift toward domestic investments, energy efficiency, EV charging stations, and grid upgrades to stabilize net income.

Key Points

A forecast of COVID-19 revenue declines, weaker U.S. exports, and a shift to energy efficiency and grid upgrades.

✅ Q1 profit fell 14%; net income $1.53B vs $1.77B

✅ Exports to U.S. Northeast weaker; revenue off ~$130M Mar-Jun

✅ Strategy: energy efficiency, EV charging, grid, dam upgrades

Hydro-Québec expects the coronavirus pandemic to chop “hundreds of millions of dollars” off 2020 profits, its new chief executive officer said.

COVID-19 has depressed revenue by about $130 million between March and June, Sophie Brochu said Monday, as residential electricity use rose even while overall consumption dropped. Shrinking electricity exports to the U.S. northeast are poised to compound the shortfall, she said.

“What we’re living through is not small. The impacts are real,” Brochu said on a conference call with reporters, noting that utilities such as Hydro One supported Ontario's COVID-19 response at the height of the pandemic. “I’m not talking about a billion. I’m talking about hundreds of millions. We have no idea how quickly the economy will restart. As we approach the fall we will have a better view.”

Hydro-Québec last month reported a 14-per-cent drop in first-quarter profit and warned full-year results would fall short of targets as the COVID-19 crisis weighs on power demand. Net income in the quarter was $1.53 billion compared with $1.77 billion a year ago, the company said.

Canada’s biggest electricity producer had earlier been targeting 2020 profit of between $2.8 billion and $3 billion, according to its current strategic plan and corporate structure currently in place.

The first quarter was the utility’s last under former CEO Eric Martel, who left to take over at jetmaker Bombardier Inc. Brochu, who previously ran Énergir, replaced him April 6.

To boost exports over time, Brochu said Hydro-Québec will look to strengthen ties with neighbours such as Ontario, where the Hydro One CEO is working to repair relations with government and investors, and the U.S. The CEO said she’s heartened by New York Governor Andrew Cuomo’s call last month for new power lines from Canada and upstate to promote clean energy.

“This is a clear, encouraging signal that must express itself through very concrete negotiations,” she said. “The United States is our backyard. This is true for Ontario, where key system staff lockdowns were even contemplated, and the Atlantic provinces as well. This is our ecosystem, and we intend to build on our footprint, on the relationships that we have.”

Though stricter environmental hurdles make it more complicated to get power lines built today than a decade ago, the CEO insists it’s still possible to sell electricity to neighbouring U.S. states.

“Is it more difficult today to build energy projects? The answer is yes,” she said. “Does this clog up the U.S. northeast market? Not at all. I believe this federation of ecosystems is very promising.”

In the meantime, Hydro-Québec is planning to speed up investments at home — for example, by building new charging stations that will be needed to serve a growing fleet of electric cars. The utility will also upgrade some of its Montreal-area facilities, as well as its massive dams on the Manicouagan River, Brochu said. The investments will result in additional capacity.

“Today we need to put water in the pump of Quebec, so we will concentrate our human and financial efforts here,” she said. “We are needed in Quebec.” 

Hydro-Québec is stepping up efforts to promote energy efficiency among its customer base, amid retroactive billing concerns, which Brochu said could postpone the need to build large dams.

“We have to move towards ‘no-regret moves.’ What’s a no-regret move? It’s energy efficiency,” Brochu said earlier Monday during a presentation to the Chamber of Commerce of Metropolitan Montreal, noting that Ontario debated peak rate relief for self-isolating customers. “This is healthy, it’s fundamental and it will contribute to Quebec’s economic rebound by lowering energy costs.”

Brochu also pledged to build a more diverse workforce after the company said last week that 8.2 per cent of staff belong to “visible and ethnic” minorities.

“This can be improved on,” she said. “What I’m expressing today is my determination, and that of the management team, to move the needle.”

COVID-19 Solar Job Losses are erasing five years of workforce growth, SEIA reports, with U.S. installations and capacity down, layoffs accelerating, 3 GW expected in Q2, and policy support key for economic recovery.

Key Points

COVID-19 Solar Job Losses describe the pandemic-driven decline in U.S. solar employment, installations, and capacity.

✅ SEIA reports a 38% national drop in solar jobs

✅ Q2 installs projected at 3 GW, below forecasts

✅ Layoffs outpace U.S. economy without swift policy aid

Job losses associated with the COVID-19 crisis have wiped out the past five years of workforce growth in the solar energy field, according to a new industry analysis.

The expected June 2020 solar workforce of 188,000 people across the United States is 114,000 below the pre-pandemic forecast of 302,000 workers, a shortfall tied to the solar construction slowdown according to the Solar Energy Industries Association, which said in a statement Monday that the solar industry is now losing jobs at a faster rate than the U.S. economy.

In Massachusetts, the loss of 4,284 solar jobs represents a 52 percent decline from previous projections, according to the association’s analysis.

The national 38 percent drop in solar jobs coincides with a 37 percent decrease in expected solar installations in the second quarter of 2020, and similar pressures have put wind investments at risk across the sector, the association stated. The U.S. is now on track to install 3 gigawatts of new capacity this quarter, though subsequent forecasts anticipated solar and storage growth as investments returned, and the association said the decrease from the expected capacity is equivalent to the electricity needed to power 288,000 homes.

“Thousands of solar workers are being laid off each week, but with swift action from Congress, we know that solar can be a crucial part of our economic recovery,” with proposals such as the Biden solar plan offering a potential policy path, SEIA President and CEO Abigail Ross Hopper said in a statement, as recent analyses point to US solar and wind growth under supportive policies.

Subsequent data showed record U.S. panel shipments as the market rebounded.

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.
