Heathrow Airport Power Outage 2025 disrupted operations with mass flight cancellations and diversions after a grid failure, exposing infrastructure resilience gaps, crisis management flaws, and raising passenger compensation and safety oversight concerns.

 

Key Points

A grid failure closed Heathrow, causing mass cancellations and diversions, exposing resilience and communication lapses.

✅ Grid fire triggered airport-wide shutdown

✅ 1,400+ flights canceled or diverted

✅ Inquiry probes resilience, communication, compensation

 

On March 21, 2025, Heathrow Airport, Europe's busiest, suffered a catastrophic power outage, similar to another high-profile outage seen at major events, that led to the cancellation and diversion of over 1,400 flights, affecting nearly 300,000 passengers and costing airlines an estimated £100 million. The power failure, triggered by a fire at an electricity substation in west London, left Heathrow with a significant operational crisis. This disruption is even more significant considering that Heathrow is one of the most expensive airports globally, which raises concerns about its infrastructure resilience and broader electricity system resilience across Europe.

In a parliamentary committee meeting, Heathrow officials admitted that vulnerabilities in the airport’s power supply were flagged just days before the outage. Nigel Wicking, Chief Executive of the Heathrow Airline Operators' Committee (HAOC), informed MPs that concerns regarding power resilience had been raised on March 15, following disruptions caused by cable thefts impacting runway lights. Despite these warnings, the airport’s management did not address the vulnerabilities urgently, even as UK net zero policies continue to reshape infrastructure planning, which ultimately led to the disastrous outage.

The airport was closed for a day, with serious consequences for not only airlines but also the surrounding community and businesses. British Airways alone faced millions of pounds in losses, and passengers experienced significant emotional distress, missing vital life events like weddings and funerals due to flight cancellations. The committee is now questioning officials from National Grid and Scottish and Southern Electricity Networks to better understand why Heathrow’s infrastructure failed, in the context of a cleaner grid following the British carbon tax that reduced coal use, how it communicated with affected parties, and what measures will be taken to compensate impacted passengers.

Heathrow’s Chief Executive, Thomas Woldbye, defended the closure decision, stating it would have been disastrous to keep the airport open under such circumstances. He noted that continuing operations would have left tens of thousands of passengers stranded and would have posed safety risks due to the failure of fire surveillance and CCTV systems. However, Wicking, representing the airlines, pointed out that Heathrow’s lack of resilience was unacceptable given the amount spent on the airport, emphasizing the need for better infrastructure, including addressing SF6 in switchgear during upgrades, and more transparent management practices.

Looking forward, the MPs intend to investigate the airport’s emergency preparedness, why the resilience review from 2018 wasn’t shared with airlines, and whether enough preventative measures were in place amid surging data demand that could strain electricity supplies. The outcome of this inquiry could have lasting effects on how Heathrow and other major airports handle their infrastructure and crisis management systems, as drought-driven hydro challenges demonstrate the wider climate stresses on power networks.

Hydro-Quebec adopts a corporate structure designed to optimize the energy transition

Hydro-Québec Unified Corporate Structure advances the energy transition through integrated planning, strategy, infrastructure delivery, and customer operations, aligning generation, transmission, and distribution while ensuring non-discriminatory grid access and agile governance across assets and behind-the-meter technologies.

 

Key Points

A cross-functional model aligning strategy, planning, and operations to accelerate Quebec's low-carbon transition.

✅ Four groups: strategy, planning, infrastructure, operations.

✅ Ensures non-discriminatory transmission access compliance.

✅ No staff reductions; staged implementation from Feb 28.

 

As Hydro-Que9bec prepares to play a key role in the transition to a low-carbon economy, the complexity of the work to be done in the coming decade requires that it develop a global vision of its operations and assets, from the drop of water entering its turbines to the behind-the-meter technologies marketed by its subsidiary Hilo. This has prompted the company to implement a new corporate structure that will maximize cooperation and agility, including employee-led pandemic support that builds community trust, making it possible to bring about the energy transition efficiently with a view to supporting the realization of Quebecers’ collective aspirations.

Toward a single, unified Hydro

Hydro-Québec’s core mission revolves around four major functions that make up the company’s value chain, alongside policy choices like peak-rate relief during emergencies. These functions consist of:

  1. Developing corporate strategies based on current and future challenges and business opportunities
  2. Planning energy needs and effectively allocating financial capital, factoring in pandemic-related revenue impacts on demand and investment timing
  3. Designing and building the energy system’s multiple components
  4. Operating assets in an integrated fashion and providing the best customer experience by addressing customer choice and flexibility expectations across segments.

Accordingly, Hydro-Québec will henceforth comprise four groups respectively in charge of strategy and development; integrated energy needs planning; infrastructure and the energy system; and operations and customer experience, including billing accuracy concerns that can influence satisfaction. To enable the company to carry out its mission, these groups will be able to count on the support of other groups responsible for corporate functions.

Across Canada, leadership changes at other utilities highlight the need to rebuild ties with governments and investors, as seen with Hydro One's new CEO in Ontario.

“For over 20 years, Hydro-Québec has been operating in a vertical structure based on its main activities, namely power generation, transmission and distribution. This approach must now give way to one that provides a cross-functional perspective allowing us to take informed decisions in light of all our needs, as well as those of our customers and the society we have the privilege to serve,” explained Hydro-Québec’s President and Chief Executive Officer, Sophie Brochu.

In terms of gender parity, the management team continues to include several men and women, thus ensuring a diversity of viewpoints.

Hydro-Québec’s new structure complies with the regulatory requirements of the North American power markets, in particular with regard to the need to provide third parties with non-discriminatory access to the company’s transmission system. The frameworks in place ensure that certain functions remain separate and help coordinate responses to operational events such as urban distribution outages that challenge continuity of service.

These changes, which will be implemented gradually as of Monday, February 28, do not aim to achieve any staff reductions.

Iran, Iraq Discuss Further Cooperation in Energy Sector

Iran-Iraq Electricity Cooperation advances with power grid synchronization, cross-border energy trade, 400-kV transmission lines, and education partnerships, boosting grid reliability, infrastructure investment, and electricity exports between Tehran and Baghdad for improved supply and stability.

 

Key Points

A bilateral initiative to synchronize grids, expand networks, and sustain electricity exports, improving reliability.

✅ 400-kV Amarah-Karkheh line enables synchronized operations.

✅ Extends electricity export contracts to meet Iraq demand.

✅ Enhances grid reliability, training, and infrastructure investment.

 

Aradakanian has focused his one-day visit to Iraq on discussions pertaining to promoting bilateral collaboration between the two neighboring nations in the field of electricity, grid development deals and synchronizing power grid between Tehran and Baghdad, cooperating in education, and expansion of power networks.

He is also scheduled to meet with Iraqi top officials in a bid to boost cooperation in the relevant fields.

Back in December 2019, Ardakanian announced that Iran will continue exports of electricity to Iraq by renewing earlier contract as it is supplying about 40% of Iraq's power today.

"Iran has signed a 3-year-long cooperation agreement with Iraq to help the country's power industry in different aspects. The documents states at its end that we will export electricity to Iraq as far as they need," Ardakanian told FNA on December 9, 2019.

The contract to "export Iran's electricity" to Iraq will be extended, he added.

Ardakanian also said that Iran and Iraq's power grids have become synchronized in a move that supports Iran's regional power hub plans since a month ago.

In 2004 Iran started selling electricity to Iraq. Iran electricity exports to the western neighbor are at its highest level of 1,361 megawatts per day now, as the country weighs summer power sufficiency ahead of peak demand.

The new Amarah-Karkheh 400-KV transmission line stretching over 73 kilometers, is now synchronized to provide electricity to both countries, reflecting regional power export trends as well. It also paves the way for increasing export to power-hungry Iraq in the near future.

With synchronization of the two grids, the quality of electricity in Iraq will improve as the country explores nuclear power options to tackle shortages.

According to official data, 82% of Iraq's electricity is generated by thermal power plants that use gas as feedstock, while Iran is converting thermal plants to combined cycle to save energy. This is expected to reach 84% by 2027.

New Program Set to Fight for 'Electricity Future That Works for People and the Planet'

Energy Justice Program drives a renewables-based transition, challenging utility monopolies with legal action, promoting rooftop solar, distributed energy, public power, and climate justice to decarbonize the grid and protect communities and wildlife nationwide.

 

Key Points

A climate justice initiative advancing renewables, legal action, and public power to challenge utility monopolies.

✅ Challenges utility barriers to rooftop solar and distributed energy

✅ Advances state and federal policies for equitable, public power

✅ Uses litigation to curb fossil fuel dependence and protect communities

 

The Center for Biological Diversity on Monday rolled out a new program to push back against the nation's community- and wildlife-harming energy system that the climate advocacy group says is based on fossil fuels and a "centralized monopoly on power."

The goal of the new effort, the Energy Justice Program, is to help forge a path towards a just and renewables-based energy future informed by equitable regulation principles.

"Our broken energy system threatens our climate and our future," said Jean Su, the Energy Justice Program's new director, in a statement. "Utilities were given monopolies to ensure public access to electricity, but these dinosaur corporations are now hurting the public interest by blocking the clean energy transition, including via coal and nuclear subsidy schemes that profit off the fossil fuel era."

"In this era of climate catastrophe," she continued, "we have to stop these outdated monopolies and usher in a new electricity future that works for people and the planet."

To meet those goals, the new program will pursue a number of avenues, including using legal action to fight utilities' obstruction of clean energy efforts, helping communities advance local solar programs through energy freedom strategies in the South, and crafting energy policies on the state, federal, and international levels in step with commitments from major energy buyers to achieve a 90% carbon-free goal by 2030.

Some of that work is already underway. In June the Center filed a brief with a federal court in a bid to block Arizona power utility Salt River Project from slapping a 60-percent electricity rate hike on rooftop solar customers—amid federal efforts to reshape electricity pricing that critics say are being rushed—a move the group described (pdf) as an obstacle to achieving "the energy transition demanded by climate science."

The Center is among the groups in Energy Justice NC. The diverse coalition seeks to end the energy stranglehold in North Carolina held by Duke Energy, which continues to invest in fossil fuel projects even as it touts clean energy and grid investments in the region.

The time for a new energy system, says the Energy Justice Program, is now, as climate change impacts increasingly strain the grid.

"Amid this climate and extinction emergency," said Su, "the U.S. can't afford to stick with the same centralized, profit-driven electricity system that drove us here in the first place. We have to seize this once-in-a-generation opportunity to design a new system of accountable, equitable, truly public power."

How Ukraine Will Keep the Lights On This Winter

Ukraine Winter Energy Strategy strengthens the power grid through infrastructure repairs, electricity imports, renewable integration, nuclear output, and conservation to ensure reliable heating, blackout mitigation, and grid resilience with international aid, generators, and transmission lines.

 

Key Points

A wartime plan to stabilize Ukraine's grid via repairs, imports, renewables, and nuclear to deliver reliable electricity.

✅ Repairs, imports, and demand management stabilize the grid.

✅ Renewables and nuclear reduce outage risks in winter.

✅ International aid supplies transformers, generators, expertise.

 

As Ukraine braces for the winter months, the question of how the country will keep the lights on has become a pressing concern, as the country fights to keep the lights on amid ongoing strikes. The ongoing war with Russia has severely disrupted Ukraine's energy infrastructure, leading to widespread damage to power plants, transmission lines, and other critical energy facilities. Despite these challenges, Ukraine has been working tirelessly to maintain its energy supply during the cold winter months, which are essential not only for heating but also for the functioning of homes, businesses, hospitals, and schools. Here's a closer look at the steps Ukraine is taking to keep the lights on this winter and ensure that its people have access to reliable electricity.

1. Repairing Damaged Infrastructure

One of the most immediate concerns for Ukraine's energy sector is the extensive damage inflicted on its power infrastructure by Russian missile and drone attacks. Since the war began in 2022, Ukraine has faced repeated attacks targeting power plants, substations, and power lines, including strikes on western regions that caused widespread outages across communities. These attacks have left parts of the country with intermittent or no electricity, and repairing the damage has been a monumental task.

However, Ukraine has made significant progress in restoring its energy infrastructure. Government agencies and energy companies have been working around the clock to repair power plants and transmission networks. Teams of technicians and engineers have been deployed to restore power to areas that have been hardest hit by Russian attacks, often under difficult and dangerous conditions. While some areas may continue to face outages, efforts to rebuild the energy grid are ongoing, with the government prioritizing critical infrastructure to ensure that hospitals, military facilities, and essential services have access to power.

2. Energy Efficiency and Conservation Measures

To cope with reduced energy availability and avoid overloading the grid, Ukrainian authorities have been encouraging energy efficiency and conservation measures. These efforts are particularly important during the winter when demand for electricity and heating is at its peak.

The government has implemented energy-saving programs, urging citizens and businesses to reduce their consumption and adopt new energy solutions that can be deployed quickly. Measures include limiting electricity use during peak hours, setting thermostats lower in homes and businesses, and encouraging the use of energy-efficient appliances. Ukrainian officials have also been promoting public awareness campaigns to educate people about the importance of energy conservation, which is crucial to avoid grid overload and ensure the distribution of power across the country.

3. Importing Energy from Abroad

To supplement domestic energy production, Ukraine has been working to secure electricity imports from neighboring countries. Ukraine has long been interconnected with energy grids in countries such as Poland, Slovakia, and Hungary, which allows it to import electricity during times of shortage. In recent months, Ukraine has ramped up efforts to strengthen these connections, ensuring that it can import electricity when domestic production is insufficient to meet demand, and in a notable instance, helped Spain during blackouts through coordinated cross-border support.

While electricity imports from neighboring countries provide a temporary solution, this is not without its challenges. The cost of importing electricity can be high, and the country’s ability to import large amounts of power depends on the availability of energy in neighboring nations; officials say there are electricity reserves and no scheduled outages if strikes do not resume. Ukraine has been actively seeking new energy partnerships and working with international organizations to secure access to electricity, including exploring the potential for importing energy from the European Union.

4. Harnessing Renewable Energy Sources

Another key part of Ukraine's strategy to keep the lights on this winter is tapping into renewable energy sources, particularly wind and solar power. While Ukraine’s energy sector has historically been dependent on fossil fuels, the country has been making strides in integrating renewable energy into its grid. Solar and wind energy are particularly useful in supplementing the national grid, especially during the winter months when demand is high.

Renewable energy sources are less vulnerable to missile strikes compared to traditional power plants, making them an attractive option for Ukraine's energy strategy. Although renewable energy currently represents a smaller portion of Ukraine’s overall energy mix, its contribution is expected to increase as the country invests more in clean energy infrastructure. In addition to reducing dependence on fossil fuels, this shift is aligned with Ukraine’s broader environmental goals and will be important for the long-term sustainability of its energy sector.

5. International Aid and Support

International support has been crucial in helping Ukraine keep the lights on during the war. Western allies, including the European Union and the United States, have provided financial assistance, technical expertise, and equipment to help restore the energy infrastructure, though Washington recently ended some grid restoration support as priorities shifted. In addition to rebuilding power plants and transmission lines, Ukraine has received advanced energy technologies and materials to strengthen its energy security.

The U.S. has sent electrical transformers, backup generators, and other essential equipment to help Ukraine restore its energy grid. The European Union has also provided both financial and technical assistance, supporting Ukraine’s efforts to integrate more renewable energy into its grid and enhancing the country’s ability to import electricity from neighboring states.

6. The Role of Nuclear Energy

Ukraine’s nuclear energy plants play a critical role in the country’s electricity supply. Before the war, nuclear power accounted for around 50% of Ukraine’s total electricity generation, and for communities near the front line, electricity is civilization that depends on reliable baseload. Despite the ongoing conflict, Ukrainian nuclear plants have remained operational, though they face heightened security risks due to the proximity of active combat zones.

In the winter months, nuclear plants are expected to continue providing a significant portion of Ukraine's electricity, which is essential for meeting the country's heating and power needs. The government has made efforts to ensure the safety and security of these plants, which remain a vital part of the country's energy strategy.

Keeping the lights on in Ukraine during the winter of 2024 is no small feat, given the war-related damage to energy infrastructure, rising energy demands, and ongoing security risks. However, the Ukrainian government has taken proactive steps to address these challenges, including repairing critical infrastructure, importing energy from neighboring countries, promoting energy efficiency, and expanding renewable energy sources. International aid and the continued operation of nuclear plants also play a vital role in ensuring a reliable energy supply. While challenges remain, Ukraine’s resilience and determination to overcome its energy crisis are clear, and the country is doing everything it can to keep the lights on through this difficult winter.

New Orleans Levees Withstood Hurricane Ida as Electricity Failed

Hurricane Ida New Orleans Infrastructure faced a split outcome: levees and pumps protected against storm surge, while the power grid collapsed as transmission lines failed, prompting large-scale restoration efforts across Louisiana and Mississippi.

 

Key Points

It summarizes Ida's impact: levees and pumps held, but the power grid failed, causing outages and slow restoration.

✅ Levees and pumps mitigated flooding and storm surge impacts.

✅ All transmission lines failed, crippling the power grid.

✅ Crews and drones assess damage; restoration may take weeks.

 

Infrastructure in the city of New Orleans turned in a mixed performance against the fury of Hurricane Ida, with the levees and pumps warding off catastrophic flooding even as the electrical grid, part of the broader Louisiana power grid, failed spectacularly.

Ida’s high winds, measuring 150 miles (240 kilometers) an hour at landfall, took out all eight transmissions lines that deliver power into New Orleans, ripped power poles in half and crumpled at least one steel transmission tower into a twisted metal heap, knocking out electricity to all of the city. A total of more than 1.2 million homes and businesses in Louisiana and Mississippi lost power. While about 90,000 customers were reconnected by Monday afternoon, many could face days without electricity, and frustration can mount as seen during the Houston outage after major storms.

In contrast, the New Orleans area’s elaborate flood defenses seem to have held up, a vindication of the Army Corps of Engineers’ $14.5 billion project to rebuild levees, flood gates and pumps in the wake of the devastation wrought by Hurricane Katrina in 2005. While there were reports of scattered deaths tied to Ida, the city escaped the kind of flooding that destroyed entire neighborhoods in Katrina’s wake, left parts of the city uninhabitable for months and claimed 1,800 lives. 

“The situation in New Orleans, as bad as it is today with the power, could be so much worse,” Louisiana Governor John Bel Edwards said Monday on the Today Show, praising the levee system’s performance. “All you have to do is go back 16 years to get a glimpse of what that would have been like.”

While the levees’ resiliency is no doubt due to the rebuilding effort that followed Katrina, the starkly different outcomes also stems from the storms’ different characteristics. Katrina slammed the coast with a 30-foot storm surge of ocean water, while preliminary estimates from Ida put its surge far lower. 


Ida’s winds, however, were stronger than Katrina’s, and that’s what ultimately took out so many power lines, a dynamic that also saw Texas utilities struggle during Harvey. Deanna Rodriguez, the chief executive officer of power provider Entergy New Orleans, declined to comment on when service would be restored, saying the company was using helicopters and drones to help assess the damage.

Michael Webber, an energy and engineering professor at the University of Texas at Austin, estimated power restoration will take days and possibly weeks, a pattern seen in Florida restoration timelines after major hurricanes, based on the initial damage reports from the storm. More than 25,000 workers from at least 32 states and Washington are mobilized to assist with power restoration efforts, similar to FPL's massive response after Irma, according to the Edison Electric Institute.

“The question is, how long will it take to rebuild these lines,” Webber said. The utilities will first need to complete their damage assessments before they can get a sense of repair timelines, a step that Gulf Power crews have highlighted in past recoveries, he said. “You can imagine that will take days at least, possibly weeks.”

The loss of electricity will have other affects as well, and even though grid resilience during the pandemic was strong, local systems face immediate constraints. Sewer substations, for example, need electricity to keep wastewater moving, said Ghassan Korban, executive director of the New Orleans Sewerage & Water Board. The storm knocked out power to about 80 of the city’s 84 pumping stations, he said at a Monday press conference. “Without electricity, wastewater backs up and can cause overflows,” he said, adding that residents should conserve water to lessen stress on the system.
