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.

Kenya Power on the spot over inflated electricity bills

Kenya Power token glitches, inflated bills disrupt prepaid meters via M-Pesa paybill 888880 and third-party vendors like Vendit and Dynamo, causing delays, fast-depleting tokens, and billing estimates; customers report weekend outages and business losses.

 

Key Points

Service failures delaying token generation and disputed charges from estimated meter readings and slow processing.

✅ Impacts M-Pesa paybill 888880 and authorized third-party vendors

✅ Causes delays, fast-depleting tokens, weekend business closures

✅ Linked to system downtime, billing estimates, meter reading gaps

 

Kenya Power is again on the spotlight following claims of inflated power bills and a glitch in its electronic payment system that made it impossible to top up tokens on prepaid meters.

Thousands of customers started experiencing the hitch in tokens generation on Friday evening, with the problem extending through the weekend.

Small businesses such as barber shops that top up multiple times a week were hardest hit.

“My business usually thrives during weekends but I was forced to close early in the evening due to lack of power although I had paid for the tokens that were never generated,” said Mr John Kamau, a fast food restaurant owner in Nairobi.

Kenya Power processes up to 200,000 electronic transactions per day for power users, with 85 per cent done through its Safaricom M-Pesa paybill number 888880.

The remaining share is handled by its authorised third party vendors such as Vendit (paybill number 501200) and Dynamo (800904), which charge a premium for the transaction.

The sole electricity distributor admitted its system encountered challenges that crippled token generation across all vendors, advising customers on prepaid meters to buy the units from Kenya Power banking halls across the country until normalcy returned.

 

STATEMENT

“The IT team is trying to figure out where the problem was before we issue a comprehensive statement on the issue,” the firm responded to Nation queries, adding that the issue had been resolved by yesterday afternoon.

Customers who use Vendit confirmed to Nation they had successfully bought tokens yesterday afternoon.

However, there have been complaints that third party vendors process tokens almost in real time, unlike Kenya Power which, despite indicating a 30 minute delay in its service promise, sometimes takes up to six hours.  

But other users complained of inflated power bills after being slapped with abnormally high charges.

 

TOKENS

The holder of account number 30624694, for instance, received a post-paid bill of Sh16,765 last month, up from Sh894 the previous month.

She indulged the company and ended up paying just over Sh1,000.

There have also been complaints of tokens getting depleted too fast. For instance, one customer who normally uses Sh4,000 per month complained of her credit running out in a week.

Kenya Power maintains it cannot read all post-paid meters across the country, compelling it to make estimates for a number of customers.

The company argues it is not cost-effective to have meter readers go to all homes. The firm recently indicated plans to put all domestic consumers on prepaid meters to reduce non-payment of electricity bills and cut operation costs on meter reading and postage.

 

POWER CONSUMPTION

The Nairobi Securities Exchange-listed firm has also adopted a new integrated customer management system to enable consumers to self-check their power consumption and understand their electricity bill and payment obligations through a phone app.

In the past, concerns have been rife that customers often encounter delays when buying tokens through paybill number 888880, unlike through other vendors.

This has raised questions on the ownership of the vendors and the cash commissions they are entitled to, with holiday scam warnings circulating in some markets as well.

 

FOUL PLAY

Kenya Power has, however, denied any foul play, saying the authorisation of other vendors was to ease pressure on its payment channel, which handles 85 per cent of the nearly 200,000 transactions per day.

“In fact we have 11 vendors, including Equitel, it’s just that people are only aware of Vendit and Dynamo because they have been aggressive in their marketing,” the company said.

Kenya Power has been battling court cases over inflated power bills after it emerged that the utility firm was backdating bills worth Sh10.1 billion from last November.

Renewable growth drives common goals for electricity networks across the globe

Energy Transition Grid Reforms address transmission capacity, interconnection, congestion management, and flexibility markets, enabling renewable integration and grid stability while optimizing network charges and access in Australia, Ireland, and Great Britain.

 

Key Points

Measures to expand transmission, boost flexibility, and manage congestion for reliable, low-carbon electricity systems.

✅ Transmission upgrades and interconnectors ease congestion

✅ Flexible markets, DER, and storage bolster grid stability

✅ Evolving network charges and access incentivize siting

 

Electricity networks globally are experiencing significant increases in the volume of renewable capacity as countries seek to decarbonise their power sectors, even as clean energy's 'dirty secret' highlights integration trade-offs, without impacting the security of supply. The scale of this change is creating new challenges for power networks and those responsible for keeping the lights on.

The latest insight paper from Cornwall Insight – Market design amidst global energy transition – looks into this issue. It examines the outlook for transmission networks, and how legacy design and policies are supporting decarbonisation, aligning with IRENA findings on renewables and shaping the system. The paper focuses on three key markets; Australia, Ireland and Great Britain (GB).

Australia's main priority is to enhance transmission capacity and network efficiency; as concerns over excess solar risking blackouts grow in distribution networks, without this, the transmission system will be a barrier to growth for decentralised flexibility and renewables. In contrast, GB and Ireland benefit from interconnection with other national markets. This provides them with additional levers that can be pulled to manage system security and supply. However, they are still trying to hone and optimise network flexibility in light of steepening decarbonisation objectives.

Unsurprisingly, renewable energy resources have been growing in all three markets, with Ireland regarded as a leader in grid integration, with this expected to continue for the foreseeable future. Many of these projects are often located in places where network infrastructure is not as well developed, creating pressure on system operation as a result.

In all three markets, unit charges are rising, driven by a reduced charging base as decentralised energy grows quickly. This combination of changes is leading to network congestion, a challenge mirrored by the US grid overhaul for renewables underway, as transmission network development struggles to keep up, and flexibility markets are being optimised and changed.

In summary, reforms are on-going in each jurisdiction to accommodate the rapid physical transformation of the generation mix. Each has its objectives and tensions which are reflective of wider global reform programmes being undertaken in most developed, liberalised and decarbonising energy markets.

Gareth Miller, CEO of Cornwall Insight, said: “Despite differences in market design and characteristics, all three markets are grappling with similar issues, that comes from committing to deep decarbonisation. This includes the most appropriate methods for charging for networks, managing access to them and dealing with issues such as network congestion and constraint.

“In all three countries, renewable projects are often placed in isolated locations, as seen in Scotland where more pylons are needed to keep the lights on, away from the traditional infrastructure that is closer to demand. However, as renewable growth is set to continue, the networks will need to transition from being demand-centric to more supply orientated.

“Both system operators and stakeholders will need to continually evaluate their market structures and designs to alleviate issues surrounding locational congestion and grid stability. Each market is at very different stages in the process in trying to improve any problems implementing solutions to allow for higher efficiencies in renewable energy integration.

“It is uncertain whether any of the proposed changes will fundamentally resolve the issues that come with increased renewables on the system. However, despite marked differences, they certainly could all learn from each other and elements of their network arrangements, as well as from US decarbonisation strategies research.”

Egypt, Eni ink MoU on hydrogen production projects

Egypt-ENI Hydrogen MoU outlines joint feasibility studies for green and blue hydrogen using renewable energy, carbon capture, and CO2 storage, targeting domestic demand, exports, and net-zero goals within Egypt's energy transition.

 

Key Points

A pact to study green and blue hydrogen in Egypt, leveraging renewables, CO2 storage, and export/demand pathways.

✅ Feasibility study for green and blue hydrogen projects

✅ Uses renewables, SMR, carbon capture, and CO2 storage

✅ Targets local demand, exports, and net-zero alignment

 

The Egyptian Electricity Holding Company (EEHC) and the Egyptian Natural Gas Holding Company (EGAS) signed a memorandum of understanding (MoU) with the Italian energy giant Eni to assess the technical and commercial feasibility of green and blue hydrogen production projects in Egypt, which many see as central to power companies' future strategies worldwide today.

Under the MoU, a study will be conducted to assess joint projects for the production of green hydrogen using electricity generated from renewable energy and supported by regional electricity interconnections where relevant, and blue hydrogen using the storage of CO2 in depleted natural gas fields, according to a statement by the Ministry of Petroleum on Thursday.

The study will also estimate the potential local market consumption of hydrogen and export opportunities, taking cues from Ontario's hydrogen economy proposal to align electricity rates for growth.

This agreement is part of Eni's objective to achieve zero net emissions by 2050 and Egypt's strategy towards diversifying the energy mix and developing hydrogen projects in collaboration with major international companies, taking note of Italy's green hydrogen initiatives in Sicily as a comparable effort.

It signed the deal with Egyptian Natural Gas Holding (EGAS) and Egyptian Electricity Holding Co. (EEHC).

The companies will carry out a joint study on producing renewable energy powered green hydrogen, informed by electrolyzer investments in similar projects, where applicable. They will also work on blue hydrogen. This involves reforming natural gas and capturing the resulting CO2, in this instance in depleted natural gas fields.

The study will also consider domestic hydrogen use and export options, including funding models like the Hydrogen Innovation Fund now in Ontario.

Eni said the MoU was in line with its plans to eliminate net emissions and emissions cancel emission intensity by 2050. The company noted the agreement was in line with Egypt’s plan for the energy transition, in which it pursues hydrogen plans with major international companies, alongside broader clean-tech collaboration such as Tesla cooperation discussions in Dubai, to accelerate progress.

Clorox accelerates goal of achieving 100% renewable electricity in the U.S. and Canada to 2021

Clorox Enel 70 MW VPPA accelerates renewable energy, sourcing Texas solar from the Roadrunner project to support 100% renewable electricity, Scope 2 reductions, and grid decarbonization through a virtual power purchase agreement starting in 2021.

 

Key Points

A 12-year virtual power purchase agreement for 70 MW of Texas solar to advance Clorox's 100% renewable electricity goal.

✅ 12-year contract supporting 100% renewable electricity by 2021

✅ Supplies 70 MW from Enel's Roadrunner solar project in Texas

✅ Cuts Scope 2 emissions via grid-delivered virtual PPA

 

The Clorox Company and a wholly owned subsidiary of Enel Green Power North America announced today the signing of a 12-year, 70 megawatt (MW) virtual power purchase agreement (VPPA) for the purchase of renewable energy, aligned with carbon-free electricity investments across the power sector beginning in 2021. Representing about half of Clorox's 100% renewable electricity goal in its operations in the U.S. and Canada, this agreement is expected to help Clorox accelerate achieving its goal in 2021, four years ahead of the company's original plan.

"Climate change and rising greenhouse gas emissions pose a real threat to the health of our planet and ultimately the long-term well-being of people globally. That's why we've taken action for more than 10 years to measure and reduce the carbon footprint of our operations," said Benno Dorer, chair and CEO, The Clorox Company. "Our agreement with Enel helps to expand U.S. renewable energy infrastructure, reflecting our view that companies like Clorox play an important role in addressing global climate change, as landmark policies like the U.S. climate deal further accelerate the transition. We believe this agreement will significantly contribute toward Clorox achieving our goal of 100% renewable electricity in our operations in the U.S. and Canada in 2021, four years earlier than originally planned. Our commitment to climate stewardship is an important pillar of our new IGNITE strategy and part of our overall efforts to drive Good Growth – growth that's profitable, sustainable and responsible."

The 70MW VPPA between Clorox and Enel Green Power North America for the purchase of renewable energy delivered to the electricity grid is for the second phase of Enel's Roadrunner solar project to be built in Texas, and complement global clean energy collaborations such as Canada-Germany hydrogen cooperation announced recently. Roadrunner is a 497-direct current megawatt (MWdc) solar project that is being built in two phases. The first phase, currently under construction, comprises around 252 MWdc and is expected to be completed by the end of 2019, while the remaining 245 MWdc of capacity is expected to be completed by the end of 2020. Once fully operational, the solar plant could generate up to 1.2 terawatt-hours (TWh) of electricity annually, while avoiding an estimated 800,000 metric tons of carbon dioxide emissions per year.

Based on the U.S. Environmental Protection Agency Greenhouse Gas Equivalencies Calculator[i], this VPPA is estimated to avoid approximately 140,000 metric tons of CO2 emissions each year. This is equivalent to the annual impact that 165,000 acres of U.S. forest can have in removing CO2 from the atmosphere, and illustrates why cleaning up Canada's electricity is central to emissions reductions in the power sector, or the carbon impact of the electricity needed to power more than 24,000 U.S. homes annually.

"We are proud to support Clorox on their path towards 100% renewable electricity in its operations in the U.S. and Canada by helping them achieve about half their goal through this agreement," said Georgios Papadimitriou, head of Enel Green Power North America. "This agreement with Clorox reinforces the continued significance of renewable energy as a fundamental part of any company's sustainability strategy."

Schneider Electric Energy & Sustainability Services advised Clorox on this power purchase agreement and, amid heightened investor attention exemplified by the Duke Energy climate report, supported the company in its project selection, analysis, negotiations and deal execution.

 

Clorox Commits to Scope 1, 2 and 3 Science-Based Targets

For more than 10 years, Clorox has consistently achieved its goals to reduce greenhouse gas emissions in its operations. Clorox is focused on setting emissions reduction targets in line with climate science. As a participant in the Science Based Targets Initiative, Clorox has committed to setting and achieving science-based greenhouse gas emissions reduction targets in its operations (Scopes 1 and 2) and across its value chain (Scope 3), and consistent with national pathways such as Canada's net-zero 2050 target pursued by policymakers. The targets are considered "science-based" if they are in line with what the latest climate science says is necessary to meet the goals of the 2015 Paris Agreement – a global environmental accord to address climate change and its negative impacts.

Clorox's climate stewardship goals are part of its new integrated corporate strategy called IGNITE, which includes several other environmental, social and governance (ESG) goals and reflects lessons from Canada's electricity progress in scaling clean power. More comprehensive information about Clorox's IGNITE ESG goals can be found here. Information on Clorox's 2020 ESG strategy can be found in its fiscal year 2019 annual report.

When paying $1 for a coal power plant is still paying too much

San Juan Generating Station eyed for $1 coal-plant sale, as Farmington and Acme propose CCS retrofit, meeting emissions caps and renewable mandates by selling captured CO2 for enhanced oil recovery via a nearby pipeline.

 

Key Points

A New Mexico coal plant eyed for $1 and a CCS retrofit to cut emissions and sell CO2 for enhanced oil recovery.

✅ $400M-$800M CCS retrofit; 90% CO2 capture target

✅ CO2 sales for enhanced oil recovery; 20-mile pipeline gap

✅ PNM projects shutdown savings; renewable and emissions mandates

 

One dollar. That’s how much an aging New Mexico coal plant is worth. And by some estimates, even that may be too much.

Acme Equities LLC, a New York-based holding company, is in talks to buy the 847-megawatt San Juan Generating Station for $1, after four of its five owners decided to shut it down. The fifth owner, the nearby city of Farmington, says it’s pursuing the bargain-basement deal with Acme to avoid losing about 1,600 direct and indirect jobs in the area amid a broader just transition debate for energy workers.

 

We respectfully disagree with the notion that the plant is not economical

Acme’s interest comes as others are looking to exit a coal industry that’s been plagued by costly anti-pollution regulations. Acme’s plan: Buy the plant "at a very low cost," invest in carbon capture technology that will lower emissions, and then sell the captured CO2 to oil companies, said Larry Heller, a principal at the holding group.

By doing this, Acme “believes we can generate an acceptable rate of return,” Heller said in an email.

Meanwhile, San Juan’s majority owner, PNM Resources Inc., offers a distinctly different view, echoing declining coal returns reported by other utilities. A 2022 shutdown will push ratepayers to other energy alternatives now being planned, saving them about $3 to $4 a month on average, PNM has said.

“We could not identify a solution that would make running San Juan Generating Station economical,” said Tom Fallgren, a PNM vice president, in an email.

The potential sale comes as a new clean-energy bill, supported by Governor Lujan Grisham, is working its way through the state legislature. It would require the state to get half of its power from renewable sources by 2030, and 100 percent by 2045, even as other jurisdictions explore small modular reactor strategies to meet future demand. At the same time, the legislation imposes an emissions cap that’s about 60 percent lower than San Juan’s current levels.

In response, Acme is planning to spend $400 million to $800 million to retrofit the facility with carbon capture and sequestration technology that would collect carbon dioxide before it’s released into the atmosphere, Heller said. That would put the facility into compliance with the pending legislation and, at the same time, help generate revenue for the plant.

The company estimates the system would cut emissions by as much as 90 percent, and the captured gas could be sold to oil companies, which uses it to enhance well recovery. The bottom line, according to Heller: “A winning financial formula.”

It’s a tricky formula at best. Carbon-capture technology has been controversial, even as new coal plant openings remain rare, expensive to install and unproven at scale. Additionally, to make it work at the San Juan plant, the company would need to figure out how to deliver the CO2 to customers since the nearest pipeline is about 20 miles (32 kilometers) away.

 

Reducing costs

Acme is also evaluating ways to reduce costs at San Juan, Heller said, including approaches seen at operators extending the life of coal plants under regulatory scrutiny, such as negotiating a cheaper coal-supply contract and qualifying for subsidies.

Farmington’s stake in the plant is less than 10 percent. But under terms of the partnership, the city — population 45,000 — can assume full control of San Juan should the other partners decide to pull out, mirroring policy debates over saving struggling nuclear plants in other regions. That’s given Farmington the legal authority to pursue the plant’s sale to Acme.

 

At the end of the day, nobody wants the energy

“We respectfully disagree with the notion that the plant is not economical,” Farmington Mayor Nate Duckett said by email. Ducket said he’s in better position than the other owners to assess San Juan’s importance “because we sit at Ground Zero.”

The city’s economy would benefit from keeping open both the plant and a nearby coal mine that feeds it, according to Duckett, with operations that contribute about $170 million annually to the local area.

While the loss of those jobs would be painful to some, Camilla Feibelman, a Sierra Club chapter director, is hard pressed to see a business case for keeping San Juan open, pointing to sector closures such as the Three Mile Island shutdown as evidence of shifting economics. The plant isn’t economical now, and would almost certainly be less so after investing the capital to add carbon-capture systems.

Victims of California's mega-fire will sue electricity company

PG&E Wildfire Lawsuit alleges utility negligence, inadequate infrastructure maintenance, and faulty transmission lines, as victims seek compensation. Regulators investigate the blaze, echoing class actions after Victoria's Black Saturday mega-fires and utility oversight failures.

 

Key Points

PG&E Wildfire Lawsuit alleges utility negligence and power line faults, seeking victim compensation amid investigations.

✅ Alleged failure to maintain transmission infrastructure

✅ Spark reports and regulator filings before blaze erupted

✅ Class action parallels with Australia's Black Saturday

 

Victims of California's most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze, a move that follows the utility's 2018 Camp Fire guilty plea in a separate case.

The suit filed on Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines, amid prior reports that power lines may have sparked fires in California.

The utility's president said earlier the company doesn't know what caused the fire, but is cooperating with the investigation by state agencies, and other utilities such as Southern California Edison have faced wildfire lawsuits in California.

PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.

A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking, and the company later promoted its wildfire assistance program for victims seeking aid.

A massive class action after Australia's last mega-fire, Victoria's Black Saturday in 2009, saw $688.5 million paid in compensation to thousands of claimants affected by the Kilmore-Kinglake and Murrindindi-Marysville fires, partly by electricity company SP Ausnet, and partly by government agencies, while in California PG&E's bankruptcy plan won support from wildfire victims addressing compensation claims.
