A fire at one nuclear power plant and the temporary shutdown of another has boosted supporters of Germany's increasingly controversial plan to close its nuclear energy program, despite concerns that coal- or gas-fired replacements will produce more greenhouse gases.

The contoversy led Swedish-based utility Vattenfall AG to dismiss its German head over a fire at the Kruemmel plant in northern Germany, and has sharpened tension over energy policy in Chancellor Angela Merkel's government.

The debate could be stoked by a far more serious incident recently at one of the world's most powerful nuclear plants in Japan, where a strong earthquake caused a transformer fire and a radioactive water leak at a facility in the northwest of the country.

The fire in a transformer building at Kruemmel on June 28, along with the temporary closedown of a second plant, Brunsbuettel, on the same day were "no promotional events for an extension of running times for nuclear power plants," said Environment Minister Sigmar Gabriel.

The fire at Kruemmel near Hamburg was brought under control with no injuries within several hours and no radioactivity leaked. But the investigation revealed flaws in communication during the incident between employees at the plant and the main operator, Vattenfall Europe AG.

Vattenfall, criticized for being slow to cooperate with investigators, recently fired Bruno Thomauske, the head of its German branch. The company said in a statement that "we want to do everything to regain trust that has been lost.... We will do everything to eliminate future mistakes and shortfalls."

The power plant in Brunsbuettel, also operated by Vattenfall, went online again after a problem at the facility's non-nuclear part was fixed.

The incidents boosted nuclear critics like Gabriel who support sticking to the 2000 shutdown law passed by the previous government of Social Democrats and Greens, under which Germany would phase out all of its 17 nuclear power plants by 2021.

Chancellor Angela Merkel's Christian Democrats are opposed in principle to abandoning nuclear energy. But they agreed to keep the shutdown plan when she and her conservatives forged the current coalition government with the left-of-center Social Democrats.

Since then, as concerns over global warming have grown, Merkel has pointed out the clash between the nuclear shutdown and Europe's goal of reducing greenhouse gases.

Power from nuclear plants, which produce little in the way of the gases believed to cause global warming, would likely be replaced by electricity generated using natural gas and coal. Environmentalists urge the use of renewable energy such as electricty generated by windmills instead, but Germany's utilities say power demand will outstrip growth in renewables, meaning more use of coal and natural gas.

The incidents, which have received widespread news coverage in Germany, are making it harder for utilities and conservatives to challenge the nuclear pullout, and give Gabriel ammunition for decisions to refuse to extend individual power plants operating lives by transferring running time from other reactors, as allowed by the 2000 law.

"The incidents at Kruemmel and Brunsbuettel show in a haunting way that the so-called remaining risk does exist and that it is way too high to take it into account longer than it is allowed by law," Gabriel said in a recent interview.

A spokesman for the Greenpeace environmental group said that Kruemmel did not meet the necessary safety standards. "It is an old plant and therefore it should be shut down," Thomas Breuer said on N24 television. The Kruemmel reactor came online in 1983 and supplies about 30 percent of the region's power, according to Vattenfall.

The local atomic energy agency in the northern town of Kiel meanwhile announced that it will question the plant's shift supervisor and several workers while the plant remains closed.

Vattenfall had initially refused to identify to investigators the employees who were on shift during the fire, and only revealed their names after investigators threatened to have police search the company.

The utility also announced that it would appoint an independent group of experts to analyze the incident and come up with a plan on how to improve security.

Nuclear power has long been a touchy subject in Germany, especially since the 1986 explosion and fire at the Chernobyl nuclear power plant in what was then the Soviet Union sent clouds of radioactive particles all the way to Germany.

As E.ON, which jointly owns the plant with Vattenfall AG, said in a statement, the incidents at Kruemmel and Bruensbuettel "have not helped to further consolidate the clearly improved image of nuclear energy."

Members of Merkel's governing conservative party have been conspicuously quiet amid news stories that work against their position that nuclear power is safe and needed.

"Safety concerns have to be a top priority when it comes to nuclear energy," Thomas Strobl, the party's secretary general for the southern state of Baden-Wuerttemberg, said. "Whoever does not understand this, discredits nuclear energy and does not live up to the responsibilities of operating such plants."

Can California Manage its Solar Boom?

California Duck Curve highlights midday solar oversupply and steep evening peak demand, stressing grid stability. Solutions include battery storage, demand response, diverse renewables like wind, geothermal, nuclear, and regional integration to reduce curtailment.

 

Key Points

A mismatch between midday solar surplus and evening demand spikes, straining the grid without storage and flexibility.

✅ Midday solar oversupply forces curtailment and wasted clean energy.

✅ Evening ramps require fast, fossil peaker plants to stabilize load.

✅ Batteries, demand response, regional trading flatten the curve.

 

California's remarkable success in adopting solar power, including a near-100% renewable milestone, has created a unique challenge: managing the infamous "duck curve." This distinctive curve illustrates a growing mismatch between solar electricity generation and the state's energy demands, creating potential problems for grid stability and ultimately threatening to slow California's progress in the fight against climate change.


The Shape of the Problem

The duck curve arises from a combination of high solar energy production during midday hours and surging energy demand in the late afternoon and evening when solar power declines. During peak solar hours, the grid often has an overabundance of electricity, and curtailments are increasing as a result, while as the sun sets, demand surges when people return home and businesses ramp up operations. California's energy grid operators must scramble to make up this difference, often relying on fast-acting but less environmentally friendly power sources.


The Consequences of the Duck Curve

The increasing severity of the duck curve has several potential consequences for California:

  • Grid Strain: The rapid ramp-up of power sources to meet evening demand puts significant strain on the electrical grid. This can lead to higher operational costs and potentially increase the risk of blackouts during peak demand times.
  • Curtailed Energy: To avoid overloading the grid, operators may sometimes have to curtail excess solar energy during midday, as rising curtailment reports indicate, essentially wasting clean electricity that could have been used to displace fossil fuel generation.
  • Obstacle to More Solar: The duck curve can make it harder to add new solar capacity, as seen in Alberta's solar expansion challenges, for fear of further destabilizing the grid and increasing the need for fossil fuel-based peaking plants.


Addressing the Challenge

California is actively seeking solutions to mitigate the duck curve, aligning with national decarbonization pathways that emphasize practicality. Potential strategies include:

  • Energy Storage: Deploying large-scale battery storage can help soak up excess solar electricity during the day and release it later when demand peaks, smoothing out the duck curve.
  • Demand Flexibility: Encouraging consumers to shift their energy use to off-peak hours through incentives and smart grid technologies can help reduce late-afternoon surges in demand.
  • Diverse Power Sources: While solar is crucial, a balanced mix of energy sources, including geothermal, wind, and nuclear, can improve grid stability and reduce reliance on rapid-response fossil fuel plants.
  • Regional Cooperation: Integrating California's grid with neighboring states can aid in balancing energy supply and demand across a wider geographical area.


The Ongoing Solar Debate

The duck curve has become a central point of debate about the future of California's energy landscape. While acknowledging the challenge, solar advocates argue for continued expansion, backed by measures like a bill to require solar on new buildings, emphasizing the urgent need to transition away from fossil fuels. Grid operators and some utility companies call for a more cautious approach, emphasizing grid reliability and potential costs if the problem isn't effectively managed.


Balancing California's Needs and its Green Ambitions

Finding the right path forward is essential; it will determine whether California can continue to lead the way in solar energy adoption while ensuring a reliable and affordable electricity supply. Successfully navigating the duck curve will require innovation, collaboration, and a strong commitment to building a sustainable energy system, as wildfire smoke impacts on solar continue to challenge generation predictability.

Opinion: With deregulated electricity, no need to subsidize nuclear power

Pennsylvania Electricity Market Deregulation has driven competitive pricing, leveraged low-cost natural gas, and spurred private investment, jobs, and efficient power plants, while nuclear subsidies threaten wholesale market signals and long-term consumer savings.

 

Key Points

Policy that opens generation to competition, leverages cheap gas, lowers rates, and resists subsidies for nuclear plants.

✅ Competitive wholesale pricing benefits consumers statewide

✅ Gas-driven plants add efficient, flexible capacity and jobs

✅ Nuclear subsidies distort market signals and raise costs

 

For decades, the government regulation of Pennsylvania's electricity markets dictated all aspects of power generation resources in the state, thus restricting market-driven prices for consumers and hindering new power plant development and investment.

Deregulation has enabled competitive markets to drive energy prices downward, as recent grid auction payouts fell 64% indicate, which has transformed Pennsylvania from a higher-electricity-cost state to one with prices below the national average.

Recently, the economic advantage of abundant low-cost natural gas has spurred an influx of billions of dollars of private capital investment and thousands of jobs to construct environmentally responsible natural gas power generation facilities throughout the commonwealth — including our three power generation facilities in operation and one presently under construction.

Calpine is an independent power provider with a national portfolio of 80 highly efficient power plants in operation or under construction with an electric generating capacity of approximately 26,000 megawatts. Collectively, these resources can provide sufficient power for more than 30 million residential homes. We are not a regulated utility receiving a guaranteed rate of return on investment. Rather, Calpine competes to sell wholesale power into the electric markets, and the economics of supply and demand are fundamental to the success of our business.

Pennsylvania's deregulated electricity market is working. Consumers are benefiting from low-cost natural gas, as broader evidence shows competition benefits consumers and the environment across markets, and companies such as Calpine are investing billions of dollars and creating thousands of jobs to build advanced, energy efficient, environmentally responsible and flexible power generating facilities.

There are presently seven electric generating projects under construction in the commonwealth, representing about a $7 billion capital investment that will produce about 7,000 megawatts of efficient electrical power, with additional facilities being planned.

Looking back 20 years following the enactment of the Pennsylvania Electricity Generation Customer Choice and Competition Act, Pennsylvania's regulators and policymakers must conclude that the results of a free and fair market-driven structure have delivered indisputable benefits to the consumer, even amid potential winter rate spikes for residents, and the Pennsylvania economy.

While consumers are now reaping the benefits of open and competitive electricity markets, we see challenges on the horizon that could threaten the foundation of those markets. Due to pressure from nuclear power generators, state policymakers throughout the nation have been increasing efforts to impact the generation mix in their respective states by offering ratepayer funded subsidies to existing nuclear generation resources or by considering a market structure overhaul in New England.

Subsidizing one power generation type over others is having a significant, negative impact on wholesale electric markets, competitive retails markets and ultimately the cost the consumer will have to pay, and can exacerbate disruptions in coal and nuclear industries that strain the economy and risk brownouts.

In Pennsylvania, these subsidies would follow nearly $9 billion already paid by ratepayers to help the commonwealth's nuclear industry transition from regulated to competitive energy markets.

The deregulation of Pennsylvania's electricity markets in the late 1990s allowed the nuclear industry to receive billions of dollars from ratepayers to recover "stranded costs" related to investments in the commonwealth's nuclear plants. These costs were negotiated amounts based on settlements with Pennsylvania's Public Utility Commission to allow the nuclear industry to prepare and transition to competitive electricity markets.

Enough is enough. Regulatory or governmental interference in well functioning markets does not lead to better outcomes. Pennsylvania's state Legislature should not pick winners and losers by enacting legislation that would create an uneven playing field that subsidizes nuclear generating resources in the commonwealth.

Latvia eyes electricity from Belarus nuclear plant

Latvia Astravets electricity imports weigh AST purchases from the Belarusian nuclear plant, impacting the Baltic grid, Lithuania market, energy security, and cross-border trading as Latvia seeks to mitigate supply risks and stabilize power flows.

 

Key Points

Proposed AST purchases of power from Belarus's Astravets plant to bolster Baltic grid supply via Lithuania.

✅ AST evaluates imports to mitigate supply risk

✅ Energy could enter Lithuania via existing trading route

✅ Debate centers on nuclear safety and Baltic grid impacts

 

Latvia’s electricity transmission system operator, AST, is looking at the possibility of purchasing electricity from the soon-to-be completed Belarusian nuclear power plant in Astravets, at a time when Ukraine's electricity exports have resumed in the region, long criticised by the Lithuanian government, Belsat TV has reported.

According to the Latvian media, the Latvian government is seeking to mitigate the risk of a possible drop in electricity supplies amid price spikes in Ireland highlighting dispatchable power concerns, given that energy trading between the Baltic states and third parties is currently carried out only through the Belarusian-Lithuanian border, including Latvian imports from Lithuania.

If AST starts importing electricity from the Belarusian plant to Latvia, in a pattern similar to Georgia's electricity imports during peak demand, the energy is expected to enter the Lithuanian market as well.

Such cross-border flows also mirror responses to Central Asia's electricity shortages seen recently.

The Lithuanian government has repeatedly criticised the nuclear power over national security and environmental safety concerns, as well as a number of emergencies that took place during construction, particularly as Europe is losing nuclear power and confronting energy security challenges.

Debates over infrastructure and safety have also intensified by projects like power lines to reactivate Zaporizhzhia in Ukraine.

The first Astravets reactor, which is being built close to the Lithuanian border in the Hrodno region, is expected to be operational by the end of 2019, a year that saw Belgium's nuclear exports rise across Europe.

Changes Coming For Ontario Electricity Consumers

Ontario Electricity Billing Changes include OEB-backed shifts to time-of-use or tiered pricing, landlord blanket elections, LDC implementation guidance, a customer choice webpage with a bill calculator, and ENDM rate mitigation messaging.

 

Key Points

They are OEB measures enabling TOU-to-tiered switching, landlord elections, LDC guidance, and ENDM bill messages.

✅ Option to switch from TOU to tiered pricing

✅ Landlord blanket elections on tenant turnover

✅ ENDM-led bill info and rate mitigation messaging

 

By David Stevens, Aird & Berlis LLP

Electricity consumers in Ontario may see a couple of electricity rate changes in their bills in the coming months.

First, as we have already discussed, as of November 1, 2020, regulated price plan customers will have the option to switch to "tiered pricing" instead of time-of-use (TOU) pricing structures. Those who switch to "tiered pricing" will see changes in their electricity bills.

The Ontario Energy Board (OEB) has now issued final amendments to the Standard Supply Service Code to support the customer election process necessary to switch from TOU pricing to tiered pricing. The main change from what was already published in previous OEB notices is that landlords will be permitted to make a "blanket election" between TOU pricing and tiered pricing that will apply each time a tenant's account reverts back to the landlord on turnover of the rental unit. In its most recent notice, the OEB acknowledges that implementing the new customer billing option as of Nov. 1 (less than two months from now) will be challenging and directs Local Distribution Companies (LDCs) who cannot meet this date to be immediately in touch with the OEB. Finally, the OEB indicates that there will be a dedicated "customer choice webpage for consumers, including a bill calculator" in place by early October.

Second, as of January 1, 2021 low-volume consumers will see additional messaging on their bills to inform them of available rate mitigation programs.

A recent proposal posted on Ontario's Regulatory Registry indicates that the Ministry of Energy, Northern Development and Mines (ENDM) proposes that LDCs and Utility Sub-Meter Providers will be required to include a new on-bill message for low-volume consumers that "will direct customers to ENDM's new web page for further information about how the province provides financial support to electricity consumers." This new requirement is planned to be in place as of January 1, 2021. In conjunction with this requirement, the ENDM plans to launch a new web page that will provide "up-to-date information about electricity bills," including information about rate mitigation programs available to consumers. Parties are invited to submit comments on the ENDM proposal by October 5, 2020.

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

Ex-SpaceX engineers in race to build first commercial electric speedboat

Arc One Electric Speedboat delivers zero-emission performance, quiet operation, and reduced maintenance, leveraging battery propulsion, aerospace engineering, and venture-backed innovation to cut noise pollution, fuel costs, and water contamination in high-performance marine recreation.

 

Key Points

Arc One Electric Speedboat is a battery-powered, zero-emission craft offering quiet, high-performance marine cruising.

✅ 475 hp, 24 ft hull, about 40 mph top speed

✅ Cuts noise, fumes, and water contamination vs gas boats

✅ Backed by Andreessen Horowitz; ex-SpaceX engineers

 

A team of former SpaceX rocket engineers have joined the race to build the first commercial electric speedboat.

The Arc Boat company announced it had raised $4.25m (£3m) in seed funding to start work on a 24ft 475-horsepower craft that will cost about $300,000.

The LA-based company, which is backed by venture capital firm Andreessen Horowitz (an early backer of Facebook and Airbnb), said the first model of the Arc One boat would be available for sale by the end of the year.

Mitch Lee, Arc’s chief executive, said he wanted to build electric boats because of the impact conventional petrol- or diesel-powered boats have on the environment.

“They not only get just two miles to the gallon, they also pump a lot of those fumes into the water,” Lee said. “In addition, there is the huge noise pollution factor [of conventional boats] and that is awful for the marine life. With gas-powered boats it’s not just carbon emissions into the air, it’s also polluting the water and causing noise pollution. Electric boats, like electric ships clearing the air on the B.C. coast, eliminate all that.”

Lee said electric vessels would also reduce the hassle of boat ownership. “I love being out on the water, being on a boat is so much fun, but owning a boat is so awful,” he said. “I have always believed that electric boats make sense. They will be quicker, quieter and way cheaper and easier to operate and maintain, with access options like an electric boat club in Seattle lowering barriers for newcomers.”

While the first models will be very expensive, Lee said the cost was mostly in developing the technology and cheaper versions would be available in the future, mirroring advances in electric aviation seen across the industry. “It is very much the Tesla approach – we are starting up market and using that income to finance research and development and work our way down market,” he said.

Lee said the technology could be applied to larger craft, and even ferries could run on electricity in the future, as projects for battery-electric high-speed ferries begin to scale.

“We started in February with no team, no money and no warehouse,” he said. “By December we are going to be selling the Arc One, and we are hiring aggressively because we want to accelerate the adoption of electric boats across a whole range of craft, including an electric-ready ferry on Kootenay Lake.”

Lee founded the company with fellow mechanical engineer Ryan Cook. Cook, the company’s chief technology officer, was previously the lead mechanical engineer at Elon Musk’s space exploration company SpaceX where he worked on the Falcon 9 rocket, the world’s first orbital class reusable rocket. In parallel, Harbour Air's electric aircraft highlights cross-sector electrification. Apart from Lee, all of Arc’s employees have some experience working at SpaceX.

The Arc boat, which would have a top speed of 40 mph, joins a number of startups rushing to make the first large-scale production of electric-powered speedboats, while a Vancouver seaplane airline demonstrates complementary progress with a prototype electric aircraft. The Monaco Yacht Club this month held a competition for electric boat prototypes to “instigate a new vision and promote all positive approaches to bring yachting into line” with global carbon dioxide emission reduction targets. Sweden’s Candela C-7 hydrofoil boat was crowned the fastest electric vessel.
