Calif. regulators eye plans for electric utilities

Cannes Film Festival Power Outage disrupts Alpes-Maritimes as an electrical substation fire and a fallen high-voltage line trigger blackouts; arson probe launched, grid resilience tested, traffic and trains snarled, Palais des Festivals on backup power.

Key Points

A May 24, 2025 blackout in Cannes disrupting events, under arson probe, exposing grid risks across Alpes-Maritimes.

✅ Substation fire and fallen high-voltage line triggered blackouts

✅ Palais des Festivals ran on independent backup power

✅ Authorities probe suspected arson; security measures reviewed

A significant power outage on May 24, 2025, disrupted the final day of the Cannes Film Festival in southeastern France. The blackout, which affected approximately 160,000 households in the Alpes-Maritimes region, including the city of Cannes, occurred just hours before the highly anticipated Palme d'Or ceremony. French authorities are investigating the possibility that the outage was caused by arson.

Details of the Outage

The power disruption began early on Saturday morning with a fire at an electrical substation near Cannes. This incident weakened the local power grid. Shortly thereafter, a high-voltage line fell at another location, further exacerbating the situation. The combined events led to widespread power outages, affecting not only the festival but also local businesses, traffic systems, and public transportation, echoing Heathrow Airport outage warnings raised days before a separate disruption. Traffic lights in parts of Cannes and the nearby city of Antibes stopped working, leading to traffic jams and confusion in city centers. Most shops along the Croisette remained closed, and local food kiosks were only accepting cash. Train service in Cannes was also disrupted. 

Impact on the Festival

Despite the challenges, festival organizers managed to keep the main venue, the Palais des Festivals, operational by switching to an independent power supply. They confirmed that all scheduled events and screenings, including the Closing Ceremony, would proceed as planned, a reminder of how grid operators sometimes avoid rolling blackouts to keep essential services running. The power was restored around 3 p.m. local time, just hours before the ceremony, allowing music to resume and the event to continue without further incident.

Investigations and Suspected Arson

French authorities, including the national gendarmerie, are investigating the possibility that the power outage was the result of arson, aligning with grid attack warnings issued by intelligence services. The prefect for the Alpes-Maritimes region, Laurent Hottiaux, condemned the "serious acts of damage to electrical infrastructures" and stated that all resources are mobilized to identify, track down, arrest, and bring to justice the perpetrators of these acts.

While investigations are ongoing, no official conclusions have been drawn regarding the cause of the outage. Authorities are working to determine whether the incidents were isolated or part of a coordinated effort, a question that also arises when utilities implement PG&E wildfire shutoffs to prevent cascading damage.

Broader Implications

The power outage at the Cannes Film Festival underscores the vulnerability of critical infrastructure to potential acts of sabotage. While the immediate impact on the festival was mitigated, the incident raises concerns about the resilience of energy systems, especially during major public events, and amid severe weather like a B.C. bomb cyclone that leaves tens of thousands without power. It also highlights the importance of having contingency plans in place to ensure the continuity of essential services in the face of unexpected disruptions.

As investigations continue, authorities are urging the public to remain vigilant and report any suspicious activities, while planners also prepare for storm-driven outages that compound emergency response. The outcome of this investigation may have implications for future security measures at large-scale events and the protection of critical infrastructure.

While the Cannes Film Festival was able to proceed with its closing events, the power outage serves as a reminder of the potential threats to public safety, as seen when a Western Washington bomb cyclone left hundreds of thousands without power, and the importance of robust security measures to safeguard against such incidents.

Germany nuclear phase-out underscores a high-stakes energy transition, trading reactors for renewables, LNG imports, and grid resilience to secure supply, cut emissions, and navigate climate policy, public opinion shifts, and post-Ukraine supply shocks.

Key Points

Germany's nuclear phase-out retires reactors, shifting to renewables, LNG, and grid upgrades for low-carbon power.

✅ Last three reactors: Neckarwestheim, Isar 2, and Emsland closed

✅ Supply secured via LNG imports, renewables, and grid flexibility

✅ Policy accelerated post-Fukushima; debate renewed after Ukraine war

The German government is phasing out nuclear power despite the energy crisis. The country is pulling the plug on its last three reactors, betting it will succeed in its green transition without nuclear power.

On the banks of the Neckar River, not far from Stuttgart in south Germany, the white steam escaping from the nuclear power plant in Baden-Württemberg will soon be a memory.

The same applies further east for the Bavarian Isar 2 complex and the Emsland complex, at the other end of the country, not far from the Dutch border.

While many Western countries depend on nuclear power, Europe's largest economy is turning the page, even if a possible resurgence of nuclear energy is debated until the end.

Germany is implementing the decision to phase out nuclear power taken in 2002 and accelerated by Angela Merkel in 2011, after the Fukushima disaster.

Fukushima showed that "even in a high-tech country like Japan, the risks associated with nuclear energy cannot be controlled 100 per cent", the former chancellor justified at the time.

The announcement convinced public opinion in a country where the powerful anti-nuclear movement was initially fuelled by fears of a Cold War conflict, and then by accidents such as Chernobyl.

The invasion of Ukraine on 24 February 2022 brought everything into question. Deprived of Russian gas, the flow of which was essentially interrupted by Moscow, Germany found itself exposed to the worst possible scenarios, from the risk of its factories being shut down to the risk of being without heating in the middle of winter.

With just a few months to go before the initial deadline for closing the last three reactors on 31 December, the tide of public opinion began to turn, and talk of a U-turn on the nuclear phaseout grew louder. 

"With high energy prices and the burning issue of climate change, there were of course calls to extend the plants," says Jochen Winkler, mayor of Neckarwestheim, where the plant of the same name is in its final days.

Olaf Scholz's government, which the Green Party - the most hostile to nuclear power - is part of, finally decided to extend the operation of the reactors to secure the supply until 15 April.

"There might have been a new discussion if the winter had been more difficult if there had been power cuts and gas shortages nationwide. But we have had a winter without too many problems," thanks to the massive import of liquefied natural gas, notes Mr Winkler.

Denmark Renewable Energy Outlook assesses Eurostat ranking, district heating and trash incineration, EV adoption, wind turbine testing expansions, and electrification to cut CO2, aligning policies with EU 2050 climate goals and green electricity usage.

Key Points

A brief analysis of Denmark's green power use, electrification, EVs, and policies needed to meet EU 2050 CO2 goals.

✅ Eurostat rank low due to trash incineration in district heating.

✅ EV adoption stalled after tax reinstatement, slowing electrification.

✅ Wind test centers expanded; electrification could cut 95% CO2.

Denmark’s low ranking in the latest figures from Eurostat regarding climate-friendly electricity, which places the country in 32nd place out of 40 countries, is partly a result of the country’s reliance on the incineration of trash to warm our homes via long-established district heating systems.

Additionally, there are not enough electric vehicles – a recent increase in sales was halted in 2016 when the government started to phase back registration taxes scrapped in 2008, and Europe’s EV slump underscores how fragile momentum can be.

Not enough green electricity being used

Denmark is good at producing green electricity, reports Politiken, but it does not use enough, and amid electricity price volatility in Europe this is bad news if it wants to fulfil the EU’s 2050 goal to eliminate CO2 emissions.

A recent report by Eurelectric and McKinsey demonstrates that if heating, transport and industry were electrified, reflecting a broader European push for electrification across the energy system, 95 percent of the country’s CO2 emissions could be eliminated by that date.

Wind turbine testing centre expansion approved

Parliament has approved the expansion of two wind turbine centres in northwest Jutland, supporting integration as e-mobility drives electricity demand in the coming years. The centres in Østerild and Høvsøre will have the capacity to test nine and seven turbines, measuring 330 and 200 metres in size (up from 250 and 165) respectively. The Østerild expansion should be completed in 2019, while Høvsøre ​​will have to wait a little longer.

Third on the Environmental Performance Index

Denmark finished third on the latest Environmental Performance Index, finishing only behind Switzerland and France. Its best category ranking was third for Environmental Health, and comparative energy efficiency benchmarking can help contextualize progress. Elsewhere, it ranked 11th for Ecosystem Vitality, 18th for Biodiversity and Habitat, 94th for Forests, 87th for Fisheries, 25th for Climate and Energy and 37th for Air Pollution, 14th for Water Resources and 7th for Agriculture.

Quebec Hydropower Export Retaliation examines using electricity exports to counter U.S. tariffs amid Canada-U.S. trade tensions, weighing clean energy supply, grid reliability, energy security, legal risks, and long-term market impacts.

Key Points

Using Quebec electricity exports as leverage against U.S. tariffs, and its economic, legal, and diplomatic consequences.

✅ Revenue loss for Quebec and higher costs for U.S. consumers

✅ Risk of legal disputes under trade and energy agreements

✅ Long-term erosion of market share and grid cooperation

As trade tensions between Canada and the United States continue to escalate, with electricity exports at risk according to recent reporting, discussions have intensified around potential Canadian responses to the imposition of U.S. tariffs. One of the proposals gaining attention is the idea of reducing or even halting the export of energy from Quebec to the U.S. This measure has been suggested by some as a potential countermeasure to retaliate against the tariffs. However, experts and industry leaders are urging caution, emphasizing that the consequences of such a decision could have significant economic and diplomatic repercussions for both Canada and the United States.

Quebec plays a critical role in energy trade, particularly in supplying hydroelectric power to the United States, especially to the northeastern states, including New York where tariffs may spike energy prices according to analysts, strengthening the case for stable cross-border flows. This energy trade is deeply embedded in the economic fabric of both regions. For Quebec, the export of hydroelectric power represents a crucial source of revenue, while for the U.S., it provides access to a steady and reliable supply of clean, renewable energy. This mutually beneficial relationship has been a cornerstone of trade between the two countries, promoting economic stability and environmental sustainability.

In the wake of recent U.S. tariffs on Canadian goods, some policymakers have considered using energy exports as leverage, echoing threats to cut U.S. electricity exports in earlier disputes, to retaliate against what is viewed as an unfair trade practice. The idea is to reduce or stop the flow of electricity to the U.S. as a way to strike back at the tariffs and potentially force a change in U.S. policy. On the surface, this approach may appear to offer a viable means of exerting pressure. However, experts warn that such a move would be fraught with significant risks, both economically and diplomatically.

First and foremost, Quebec's economy is heavily reliant on revenue from hydroelectric exports to the U.S. Any reduction in these energy sales could have serious consequences for the province's economic stability, potentially resulting in job losses and a decrease in investment. The hydroelectric power sector is a major contributor to Quebec's GDP, and recent events, including a tariff threat delaying a green energy bill in Quebec, illustrate how trade tensions can ripple through the policy landscape, while disrupting this source of income could harm the provincial economy.

Additionally, experts caution that reducing energy exports could have long-term ramifications on the energy relationship between Quebec and the northeastern U.S. These two regions have developed a strong and interconnected energy network over the years, and abruptly cutting off the flow of electricity could damage this vital partnership. Legal challenges could arise under existing trade agreements, and even as tariff threats boost support for Canadian energy projects among some stakeholders, the situation would grow more complex. Such a move could also undermine trust between the two parties, making future negotiations on energy and other trade issues more difficult.

Another potential consequence of halting energy exports is that U.S. states may seek alternative sources of energy, diminishing Quebec's market share in the long run. As the U.S. has a growing demand for clean energy, especially as it looks to transition away from fossil fuels, and looks to Canada for green power in several regions, cutting off Quebec’s electricity could prompt U.S. states to invest in other forms of energy, including renewables or even nuclear power. This could have a lasting effect on Quebec's position in the U.S. energy market, making it harder for the province to regain its footing.

Moreover, reducing or ceasing energy exports could further exacerbate trade tensions, leading to even greater economic instability. The U.S. could retaliate by imposing additional tariffs on Canadian goods or taking other measures that would negatively impact Canada's economy. This could create a cycle of escalating trade barriers that would hurt both countries and undermine the broader North American trade relationship.

While the concept of using energy exports as a retaliatory tool may seem appealing to some, the experts' advice is clear: the potential economic and diplomatic costs of such a strategy outweigh the short-term benefits. Quebec’s role as an energy supplier to the U.S. is crucial to its own economy, and maintaining a stable, reliable energy trade relationship is essential for both parties. Rather than escalating tensions further, it may be more prudent for Canada and the U.S. to seek diplomatic solutions that preserve trade relations and minimize harm to their economies.

While the idea of using Quebec’s energy exports as leverage in response to U.S. tariffs may appear attractive on the surface, and despite polls showing support for tariffs on energy and minerals among Canadians, it carries significant risks. Experts emphasize the importance of maintaining a stable energy export strategy to protect Quebec’s economy and preserve positive diplomatic relations with the U.S. Both countries have much to lose from further escalating trade tensions, and a more measured approach is likely to yield better outcomes in the long run.

Hydropower Covid-19 Resilience highlights clean, reliable energy and flexible grid services, with pumped storage, automation, and affordability supporting climate action, decarbonization, and recovery through sustainable infrastructure, policy incentives, and capacity upgrades.

Key Points

Hydropower Covid-19 Resilience is the sector's ability to ensure clean, reliable, flexible power during crises.

✅ Record 4,306 TWh in 2019, avoiding 80-100 Mt CO2e emissions.

✅ 1,308 GW installed; 15.6 GW added; flexibility and storage in demand.

✅ Policy, tax incentives, and fast-track approvals to spur projects.

The Covid-19 pandemic has underlined hydropower's resilience and critical role in delivering clean, reliable and affordable energy, especially in times of crisis, as highlighted by IAEA lessons for low-carbon electricity. This is the conclusion of two new reports published by the International Hydropower Association (IHA).

The 2020 Hydropower Status Report presents latest worldwide installed capacity and generation data, showcasing the sector's contribution to global carbon reduction efforts, with low-emissions sources projected to cover almost all demand increases in the next three years. It is published alongside a Covid-19 policy paper featuring recommendations for governments, financial institutions and industry to respond to the current health and economic crisis.

"Preventing an emergency is far better than responding to one," says Roger Gill, President of IHA, highlighting the need to incentivise investments in renewable infrastructure, a view echoed by Fatih Birol during the crisis. "The events of the past few months must be a catalyst for stronger climate action, including greater development of sustainable hydropower."

Now in its seventh edition, the Hydropower Status Report shows electricity generation hit a record 4,306 terawatt hours (TWh) in 2019, the single greatest contribution from a renewable energy source in history, aligning with the outlook that renewables to surpass coal by 2025.

The annual rise of 2.5 per cent (106 TWh) in hydroelectric generation - equivalent to the entire electricity consumption of Pakistan - helped to avoid an estimated additional 80-100 million metric tonnes of greenhouse gases being emitted last year.

The report also highlights:

* Global hydropower installed capacity reached 1,308 gigawatts (GW) in 2019, as 50 countries completed greenfield and upgrade projects, including pumped storage and repowering old dams in some regions.

* A total of 15.6 GW in installed capacity was added in 2019, down on the 21.8 GW recorded in 2018. This represents a rise of 1.2 per cent, which is below the estimated 2.0 per cent growth rate required for the world to meet Paris Agreement carbon reduction targets.

* India has overtaken Japan as the fifth largest world hydropower producer with its total installed capacity now standing at over 50 GW. The countries with the highest increases in were Brazil (4.92 GW), China (4.17 GW) and Laos (1.89 GW).

* Hydropower's flexibility services have been in high demand during the Covid-19 crisis, even as global demand dipped 15% globally, while plant operations have been less affected due to the degree of automation in modern facilities.

* Hydropower developments have not been immune to economic impacts however, with the industry facing widespread uncertainty and liquidity shortages which have put financing and refinancing of some projects at risk.

In a companion policy paper, IHA sets out the immediate impacts of the crisis on the sector, noting how European responses to Covid-19 have accelerated the electricity system transition, as well as recommendations to assist governments and financial institutions and enhance hydropower's contribution to the recovery.

The recommendations include:

• Increasing the ambition of renewable energy and climate change targets which incorporate the role of sustainable hydropower development.
• Supporting sustainable hydropower through introducing appropriate financial measures such as tax incentives to ensure viable and shovel-ready projects can commence.
• Fast-tracking planning approvals to ensure the development and modernisation of hydropower projects can commence as soon as possible, in line with internationally recognised sustainability guidelines.
• Safeguarding investment by extending deadlines for concession agreements and other awarded projects.
• Given the increasing need for long-duration energy storage such as pumped storage, working with regulators and system operators to develop appropriate compensation mechanisms for hydropower's flexibility services.

Bruce Power Capacity Uprate boosts nuclear output through generator stator upgrades, turbine and transformer enhancements, and cooling pump improvements at Bruce A and B, unlocking megawatts and efficiency gains from legacy heavy water design capacity.

Key Points

Upgrades that raise Bruce Power capacity via stator, turbine, transformer, and cooling enhancements.

✅ Generator stator replacement increases electrical conversion efficiency

✅ Turbine and transformer upgrades enable higher MW output

✅ Cooling pump enhancements optimize plant thermal performance

Bruce Power’s Unit 3 nuclear reactor will squeeze out an extra 22 megawatts of electricity, thanks to upgrades during its recent planned outage for refurbishment.

Similar gains are anticipated at its three sister reactors at Bruce A generating station, which presents the opportunity for the biggest efficiency gains and broader economic benefits for Ontario, due to a design difference over Bruce B’s four reactors, Bruce Power spokesman John Peevers said.

Bruce A reactor efficiency gains stem mainly from the fact Bruce A’s non-nuclear side, including turbines and the generator, was sized at 88 per cent of the nuclear capacity, Peevers said, while early Bruce C exploration work advances.

This allowed 12 per cent of the energy, in the form of steam, to be used for heavy water production, which was discontinued at the plant years ago. Heavy water, or deuterium, is used to moderate the reactors.

That design difference left a potential excess capacity that Bruce Power is making use of through various non-nuclear enhancements. But the nuclear operator, which also made major PPE donations during the pandemic, will be looking at enhancements at Bruce B as well, Peevers said.

Bruce Power’s efficiency gain came from “technology advancements,” including a “generator-stator improvement project that was integral to the uprate,” and contributed to an operating record at the site, a Bruce Power news release said July 11.

Peevers said the stationary coils and the associated iron cores inside the generator are referred to as the stator. The stator acts as a conductor for the main generator current, while the turbine provides the mechanical torque on the shaft of the generator.

“Some of the other things we’re working on are transformer replacement and cooling pump enhancements, backed by recent manufacturing contracts, which also help efficiency and contribute to greater megawatt output,” Peevers said.

The added efficiency improvements raised the nuclear operator’s peak generating capacity to 6,430 MW, as projects like Pickering life extensions continue across Ontario.
