The Tennessee Valley Authority has cut power generation in half at its largest nuclear plant to avoid overheating the Tennessee River in Alabama, costing the utility millions of dollars.

The Chattanooga Times Free Press reports the nation's largest public utility has already lost nearly $50 million in power generation at the Browns Ferry Nuclear Plant near Athens, Ala. Unless the summer cools down, TVA could lose more, pushing up fuel costs and consumer electric bills even after seven straight monthly increases.

TVA executives said the Browns Ferry Plant has operated at about half power for most of the past month and could remain slowed down through September.

TVA President Tom Kilgore said "all the radiant heat gets in the river when you have a summer as hot as this has been."

Among the nation's 66 nuclear plants, Browns Ferry has been the one hardest hit by concerns about overheated river water, according to the Nuclear Energy Institute and TVA. With three-reactors, it is TVA's biggest nuclear facility.

TVA has reduced power production at Browns Ferry at least 39 days since July 8 because of the high river temperature.

Just recently, TVA violated its permit with the Alabama Department of Environmental Management when the river temperature topped 90 degrees.

The cutback means TVA is losing 1,500 megawatts of power generation just when it's needed most. For each day of 50 percent power at Browns Ferry, the utility spends more than $1 million extra to pay for replacement power, utility executives said. The extra cost is added to ratepayer bills in the monthly fuel cost adjustment, which is up by more than 25 percent since March.

When the Tennessee River flows into the Guntersville Reservoir around Browns Ferry, the river widens and slows. The plant draws in river water to cool its equipment, then releases it back into the river. TVA uses mechanical draft cooling towers to help pull heat out of the cooling water before it is released.

Most U.S. nuclear plants are on an ocean or one of the Great Lakes or have closed-loop cooling systems that don't rely as much upon water from nearby rivers or lakes.

TVA's Watts Bar Nuclear Plant in Spring City has a closed-loop system. The Sequoyah plant near Soddy-Daisy uses less river water than Browns Ferry and has two cooling towers. TVA also plans a closed-loop system with twin cooling towers at the Bellefonte plant planned in Hollywood, Ala.

Two coal-fired TVA plants Cumberland, west of Nashville, and Colbert, near Muscle Shoals, Ala. have also had production slowdowns this summer but not as much as Browns Ferry.

During a public hearing before the TVA board last week, anti-nuclear activist Margaret Klein, of Knoxville, said nuclear plants are bound to encounter more thermal problems on the Tennessee River as global warming raises river temperatures.

The utility supplies power to nearly 9 million consumers in Tennessee, Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.

TCA Electric Leads Hydrogen Crane Project at Vancouver Port

Hydrogen Fuel Cell Crane Port of Vancouver showcases zero-emission RTG technology by DP World, TCA Electric, and partners, using hydrogen-electric fuel cells, battery energy storage, and regenerative capture to decarbonize container handling operations.

 

Key Points

A retrofitted RTG crane powered by hydrogen fuel cells, batteries, and regeneration to cut diesel use and CO2 emissions.

✅ Dual fuel cell system charges high-voltage battery

✅ Regenerative capture reduces energy demand and cost

✅ Pilot targets zero-emission RTG fleets by 2040

 

In a groundbreaking move toward sustainable logistics, TCA Electric, a Chilliwack-based industrial electrical contractor, is at the forefront of a pioneering hydrogen fuel cell crane project at the Port of Vancouver. This initiative, led by DP World in collaboration with TCA Electric and other partners, marks a significant step in decarbonizing port operations and showcases the potential of hydrogen technology in heavy-duty industrial applications.

A Vision for Zero-Emission Ports

The Port of Vancouver, Canada's largest port, has long been a hub for international trade. However, its operations have also contributed to substantial greenhouse gas emissions, even as DP World advances an all-electric berth in the U.K., primarily from diesel-powered Rubber-Tired Gantry (RTG) cranes. These cranes are essential for container handling but are significant sources of CO₂ emissions. At DP World’s Vancouver terminal, 19 RTG cranes account for 50% of diesel consumption and generate over 4,200 tonnes of CO₂ annually. 

To address this, the Vancouver Fraser Port Authority and the Province of British Columbia have committed to transforming the port into a zero-emission facility by 2050, supported by provincial hydrogen investments that accelerate clean energy infrastructure across B.C. This ambitious goal has spurred several innovative projects, including the hydrogen fuel cell crane pilot. 

TCA Electric’s Role in the Hydrogen Revolution

TCA Electric's involvement in this project underscores its expertise in industrial electrification and commitment to sustainable energy solutions. The company has been instrumental in designing and implementing the electrical systems that power the hydrogen fuel cell crane. This includes integrating the Hydrogen-Electric Generator (HEG), battery energy storage system, and regenerative energy capture technologies. The crane operates using compressed gaseous hydrogen stored in 15 pressurized tanks, which feed a dual fuel cell system developed by TYCROP Manufacturing and H2 Portable. This system charges a high-voltage battery that powers the crane's electric drive, significantly reducing its carbon footprint. 

The collaboration between TCA Electric, TYCROP, H2 Portable, and HTEC represents a convergence of local expertise and innovation. These companies, all based in British Columbia, have leveraged their collective knowledge to develop a world-first solution in the industrial sector, while regional pioneers like Harbour Air's electric aircraft illustrate parallel progress in aviation. TCA Electric's leadership in this project highlights its role as a key enabler of the province's clean energy transition. 

Demonstrating Real-World Impact

The pilot project began in October 2023 with the retrofitting of a diesel-powered RTG crane. The first phase included integrating the hydrogen-electric system, followed by a one-year field trial to assess performance metrics such as hydrogen consumption, energy generation, and regenerative energy capture rates. Early results have been promising, with the crane operating efficiently and emitting only steam, compared to the 400 kilograms of CO₂ produced by a comparable diesel unit. 

If successful, this project could serve as a model for decarbonizing port operations worldwide, mirroring investments in electric trucks at California ports that target landside emissions. DP World plans to consider converting its fleet of RTG cranes in Vancouver and Prince Rupert to hydrogen power, aligning with its global commitment to achieve carbon neutrality by 2040.

Broader Implications for the Industry

The success of the hydrogen fuel cell crane pilot at the Port of Vancouver has broader implications for the shipping and logistics industry. It demonstrates the feasibility of transitioning from diesel to hydrogen-powered equipment in challenging environments, and aligns with advances in electric ships on the B.C. coast. The project's success could accelerate the adoption of hydrogen technology in other ports and industries, contributing to global efforts to reduce carbon emissions and combat climate change.

Moreover, the collaboration between public and private sectors in this initiative sets a precedent for future partnerships aimed at advancing clean energy solutions. The support from the Province of British Columbia, coupled with the expertise of companies like TCA Electric and utility initiatives such as BC Hydro's vehicle-to-grid pilot underscore the importance of coordinated efforts in achieving sustainability goals.

Looking Ahead

As the field trial progresses, stakeholders are closely monitoring the performance of the hydrogen fuel cell crane. The data collected will inform decisions on scaling the technology and integrating it into broader port operations. The success of this project could pave the way for similar initiatives in other regions, complementing the province's move to electric ferries with CIB support, promoting the widespread adoption of hydrogen as a clean energy source in industrial applications.

TCA Electric's leadership in this project exemplifies the critical role of skilled industrial electricians in driving the transition to sustainable energy solutions. Their expertise ensures the safe and efficient implementation of complex systems, making them indispensable partners in the journey toward a zero-emission future.

The hydrogen fuel cell crane pilot at the Port of Vancouver represents a significant milestone in the decarbonization of port operations. Through innovative partnerships and local expertise, this project is setting the stage for a cleaner, more sustainable future in global trade and logistics.

Hydro-Quebec shocks cottage owner with $5,300 in retroactive charges

Hydro-Quebec back-billing arises from analogue meter errors and estimated consumption, leading to arrears for electricity usage; disputes over access, payment plans, and potential power diversion reviews can impact cottage owners near Gatineau.

 

Key Points

Hydro-Quebec back-billing recovers underbilled electricity from analogue meter errors or prolonged estimated use.

✅ Triggered by inaccurate analogue meters or missed readings

✅ Based on actual usage versus prior estimated consumption

✅ Payment plans may spread arrears; theft checks may adjust

 

A relaxing lakefront cottage has become a powerful source of stress for an Ottawa woman who Hydro-Quebec is charging $5,300 to cover what it says are years of undercharging for electricity usage.

The utility said an old analogue power meter is to blame for years of inaccurate electricity bills for the summer getaway near Gatineau, Que.

Separate from individual billing issues, Hydro-Quebec has also reported pandemic-related losses earlier this year.

Owner Jan Hodgins does not think she should be held responsible for the mistake, nor does she understand how her usage could have surged over the years.

“I’m very hydro conscious, because I was raised that way. When you left a room, you always turned the light out,” she told CTV Montreal on Wednesday, relating her shock after receiving some hefty bills from Hydro-Quebec on Sept. 22.

Hodgins said she mainly uses the cottage on weekends, does not heat the place when she is not there, and does not use a washer or dryer, to keep her energy footprint as small as possible. She’s owned the cottage for 14 years, during which she says her monthly bill has hovered around $40.

Hydro-Quebec said it has not had an accurate reading of her usage for several years, relying instead on consumption estimates to determine what she pays. The company recently reviewed her energy consumption back to 2014, and found their estimates were not accurate.

“In the past, she was consuming about 10 to 15 kilowatt hours per day. This summer she was more around 40 kilowatt hours per day,” Marc-Antoine Pouliot with Hydro-Quebec told CTV Ottawa.

Hodgins said that means her regular bill will now be more than twice the $200 her neighbours are paying for hydro each month, even with peak hydro rates in place.

Hydro-Quebec said it will correct the bill if its technicians discover that someone is illegally diverting power nearby.

Hodgins said it’s not her fault that technicians did not check her meter in person, and chose to rely on inaccurate estimates. Pouliot argues that reaching her cottage was too difficult.

“There was too much snow. There were conditions during the winter disconnection ban period, and the consequence was that people, our workers, were not able to reach the meter,” he said.

Hydro-Quebec said it is willing to stretch out the debt into monthly payments over a year, which Hodgins said amount to $440 per month on top of her regular bill.

Utilities also caution customers about scammers threatening shutoffs during billing disputes.

“I’m on a fixed income. I don’t have that kind of money. I’m completely distraught,” she said. “I don’t know what I’m going to do.”

Fish boom prompts energy conglomerate to spend $14.5M to bury subsea cables

Maritime Link Cable Burial safeguards 200-kV subsea cables in the Cabot Strait as Emera and Nova Scotia Power trench lines to mitigate bottom trawling risks from a redfish boom, ensuring Muskrat Falls hydro delivery.

 

Key Points

Trenching Cabot Strait subsea power cables to prevent redfish-driven bottom trawling and ensure Muskrat Falls power.

✅ $14.492M spent trenching 59 km at 400 m depth

✅ Protects 200-kV, 170-km subsea interconnects from trawls

✅ Driven by Gulf redfish boom; DFO and UARB consultations

 

The parent company of Nova Scotia Power disclosed this week to the Utility and Review Board, amid Site C dam watchdog attention to major hydro projects, that it spent almost $14,492,000 this summer to bury its Maritime Links cables lying on the floor of the Cabot Strait between Newfoundland and Cape Breton.

It's a fish story no one saw coming, at least not Halifax-based energy conglomerate Emera.

The parent company of Nova Scotia Power disclosed this week to the Utility and Review Board that it spent almost $14,492,000 this summer to bury its Maritime Link cables lying on the floor of the Cabot Strait between Newfoundland and Cape Breton.

The cables were protected because an unprecedented explosion in the redfish population in the Gulf of St Lawrence is about to trigger a corresponding boom in bottom trawling in the area.

Also known as ocean perch, redfish were not on anyone's radar when the $1.5-billion Maritime Link was designed and built to carry Muskrat Falls hydroelectricity from Newfoundland to Nova Scotia.

The two 200-kilovolt electrical submarine cables spanning the Cabot Strait are the longest in North America, compared with projects like the New England Clean Power Link planned further south. They are each 170 kilometres long and weigh 5,500 tonnes.

Nova Scotia Power customers are paying for the Maritime Link in return for a minimum of 20 per cent of the electricity generated by Muskrat Falls over 35 years.

The electricity is supposed to start sending first electricity through the Maritime Link in mid-2020.

First time cost disclosed
In August, the company buried 59 kilometres of subsea cables one metre below the bottom at depths of 400 metres.

"These cables had not been previously trenched due to the absence of fishing activities at those depths when the cables were originally installed," spokesperson Jeff Myrick wrote in an email to CBC News in October.

Ratepayers will get the bill next year, as utilities also face risks like copper theft that can drive costs in the region. Until now, the company had declined to release costs relating to protecting the Maritime Link.

The bill will be presented to regulators, a process that has affected projects such as a Manitoba Hydro line to Minnesota, when the company applies to recover Maritime Link costs from Nova Scotia Power ratepayers in 2020.

Myrick said the company was acting after consultation with the Department of Fisheries and Oceans.

Unexpected consequences
After years of overfishing in the 1980s and early 1990s, redfish quotas were slashed and a moratorium imposed on some redfish.

Confusingly, there are actually two redfish species in the Gulf of St. Lawrence.

But very strong recent year classes, that have coincided with warming waters in the gulf, as utilities adapt to climate change considerations grow, have produced redfish in massive numbers.

There is now believed to be three-million tonnes of redfish in the Gulf of St Lawrence.

The Department of Fisheries and Oceans is expected to increase quotas in the coming years and the fishing industry is gearing up in a big way.

Earlier this month, Scotia Harvest announced it will begin construction of a new $14-million fish plant in Digby next spring in part to process increased redfish catches.

Purdue: As Ransomware Attacks Increase, New Algorithm May Help Prevent Power Blackouts

Infrastructure Security Algorithm prioritizes cyber defense for power grids and critical infrastructure, mitigating ransomware, blackout risks, and cascading failures by guiding utilities, regulators, and cyber insurers on optimal security investment allocation.

 

Key Points

An algorithm that optimizes security spending to cut ransomware and blackout risks across critical infrastructure.

✅ Guides utilities on optimal security allocation

✅ Uses incentives to correct human risk biases

✅ Prioritizes assets to prevent cascading outages

 

Millions of people could suddenly lose electricity if a ransomware attack just slightly tweaked energy flow onto the U.S. power grid, as past US utility intrusions have shown.

No single power utility company has enough resources to protect the entire grid, but maybe all 3,000 of the grid's utilities could fill in the most crucial security gaps if there were a map showing where to prioritize their security investments.

Purdue University researchers have developed an algorithm to create that map. Using this tool, regulatory authorities or cyber insurance companies could establish a framework for protecting the U.S. power grid that guides the security investments of power utility companies to parts of the grid at greatest risk of causing a blackout if hacked.

Power grids are a type of critical infrastructure, which is any network - whether physical like water systems or virtual like health care record keeping - considered essential to a country's function and safety. The biggest ransomware attacks in history have happened in the past year, affecting most sectors of critical infrastructure in the U.S. such as grain distribution systems in the food and agriculture sector and the Colonial Pipeline, which carries fuel throughout the East Coast, prompting increased military preparation for grid hacks in the U.S.

With this trend in mind, Purdue researchers evaluated the algorithm in the context of various types of critical infrastructure in addition to the power sector, including electricity-sector IoT devices that interface with grid operations. The goal is that the algorithm would help secure any large and complex infrastructure system against cyberattacks.

"Multiple companies own different parts of infrastructure. When ransomware hits, it affects lots of different pieces of technology owned by different providers, so that's what makes ransomware a problem at the state, national and even global level," said Saurabh Bagchi, a professor in the Elmore Family School of Electrical and Computer Engineering and Center for Education and Research in Information Assurance and Security at Purdue. "When you are investing security money on large-scale infrastructures, bad investment decisions can mean your power grid goes out, or your telecommunications network goes out for a few days."

Protecting infrastructure from hacks by improving security investment decisions

The researchers tested the algorithm in simulations of previously reported hacks to four infrastructure systems: a smart grid, industrial control system, e-commerce platform and web-based telecommunications network. They found that use of this algorithm results in the most optimal allocation of security investments for reducing the impact of a cyberattack.

The team's findings appear in a paper presented at this year's IEEE Symposium on Security and Privacy, the premier conference in the area of computer security. The team comprises Purdue professors Shreyas Sundaram and Timothy Cason and former PhD students Mustafa Abdallah and Daniel Woods.

"No one has an infinite security budget. You must decide how much to invest in each of your assets so that you gain a bump in the security of the overall system," Bagchi said.

The power grid, for example, is so interconnected that the security decisions of one power utility company can greatly impact the operations of other electrical plants. If the computers controlling one area's generators don't have adequate security protection, as seen when Russian hackers accessed control rooms at U.S. utilities, then a hack to those computers would disrupt energy flow to another area's generators, forcing them to shut down.

Since not all of the grid's utilities have the same security budget, it can be hard to ensure that critical points of entry to the grid's controls get the most investment in security protection.

The algorithm that Purdue researchers developed would incentivize each security decision maker to allocate security investments in a way that limits the cumulative damage a ransomware attack could cause. An attack on a single generator, for instance, would have less impact than an attack on the controls for a network of generators, which sophisticated grid-disruption malware can target at scale, rather than for the protection of a single generator.

Building an algorithm that considers the effects of human behavior

Bagchi's research shows how to increase cybersecurity in ways that address the interconnected nature of critical infrastructure but don't require an overhaul of the entire infrastructure system to be implemented.

As director of Purdue's Center for Resilient Infrastructures, Systems, and Processes, Bagchi has worked with the U.S. Department of Defense, Northrop Grumman Corp., Intel Corp., Adobe Inc., Google LLC and IBM Corp. on adopting solutions from his research. Bagchi's work has revealed the advantages of establishing an automatic response to attacks, and analyses like Symantec's Dragonfly report highlight energy-sector risks, leading to key innovations against ransomware threats, such as more effective ways to make decisions about backing up data.

There's a compelling reason why incentivizing good security decisions would work, Bagchi said. He and his team designed the algorithm based on findings from the field of behavioral economics, which studies how people make decisions with money.

"Before our work, not much computer security research had been done on how behaviors and biases affect the best defense mechanisms in a system. That's partly because humans are terrible at evaluating risk and an algorithm doesn't have any human biases," Bagchi said. "But for any system of reasonable complexity, decisions about security investments are almost always made with humans in the loop. For our algorithm, we explicitly consider the fact that different participants in an infrastructure system have different biases."

To develop the algorithm, Bagchi's team started by playing a game. They ran a series of experiments analyzing how groups of students chose to protect fake assets with fake investments. As in past studies in behavioral economics, they found that most study participants guessed poorly which assets were the most valuable and should be protected from security attacks. Most study participants also tended to spread out their investments instead of allocating them to one asset even when they were told which asset is the most vulnerable to an attack.

Using these findings, the researchers designed an algorithm that could work two ways: Either security decision makers pay a tax or fine when they make decisions that are less than optimal for the overall security of the system, or security decision makers receive a payment for investing in the most optimal manner.

"Right now, fines are levied as a reactive measure if there is a security incident. Fines or taxes don't have any relationship to the security investments or data of the different operators in critical infrastructure," Bagchi said.

In the researchers' simulations of real-world infrastructure systems, the algorithm successfully minimized the likelihood of losing assets to an attack that would decrease the overall security of the infrastructure system.

Bagchi's research group is working to make the algorithm more scalable and able to adapt to an attacker who may make multiple attempts to hack into a system. The researchers' work on the algorithm is funded by the National Science Foundation, the Wabash Heartland Innovation Network and the Army Research Lab.

Cybersecurity is an area of focus through Purdue's Next Moves, a set of initiatives that works to address some of the greatest technology challenges facing the U.S. Purdue's cybersecurity experts offer insights and assistance to improve the protection of power plants, electrical grids and other critical infrastructure.

No deal Brexit could trigger electricity shock for Northern Ireland

Northern Ireland No-Deal Power Contingency outlines Whitehall plans to deploy thousands of generators on barges in the Irish Sea, safeguard the electricity market, and avert blackouts if Brexit disrupts imports from the Republic of Ireland.

 

Key Points

A UK Whitehall plan to prevent NI blackouts by deploying generators and protecting cross-border electricity flows.

✅ Barges in Irish Sea to host temporary power generators

✅ Mitigates loss of EU market access in a no-deal Brexit

✅ Ensures NI supply if Republic cuts electricity exports

 

Such a scenario could see thousands of electricity generators being requisitioned at short notice and positioned on barges in the Irish Sea, even as Great Britain's generation mix shapes wider supply dynamics, to help keep the region going, a Whitehall document quoted by the Financial Times states.

An emergency operation could see equipment being brought back from places like Afghanistan, where the UK still has a military presence, the newspaper said.

The extreme situation could arise because Northern Ireland shares a single energy market with the Irish Republic, where Irish grid price spikes have heightened concern about stability.

The region relies on energy imports from the Republic because it does not have enough generating capacity itself, and the UK is aiming to negotiate a deal to allow that single electricity market on the island of Ireland to continue post-EU withdrawal, while virtual power plant proposals for UK homes are explored to avoid outages, the FT stated.

However, if no Brexit deal is agreed Whitehall fears suppliers in the Irish Republic could cut off power because the UK would no longer be part of the European electricity market, and a recent short supply warning from National Grid underscores the risk.

In a bid to prevent blackouts in Northern Ireland in a worse case situation the Government would need to put thousands of generators into place, even as an emergency energy plan has reportedly not gone ahead nationwide, according to the report.

And officials fear they may need to commandeer some generators from the military in such a scenario, the FT reports.

An official was quoted by the newspaper as saying the preparations were “gob-smacking”.

Analysis: Out in the cold: how Japan's electricity grid came close to blackouts

Japan Electricity Crunch exposes vulnerabilities in a liberalised power market as LNG shortages, JEPX price spikes, snow-hit solar, and weak hedging strain energy security and retail providers amid cold snap demand and limited reserve capacity.

 

Key Points

A winter demand shock and LNG shortfalls sent JEPX to records, exposing gaps in hedging, data, and energy security.

✅ JEPX wholesale prices spiked to an all-time high

✅ LNG inventories and procurement proved insufficient

✅ Snow disabled solar; new entrants lacked hedging

 

Japan's worst electricity crunch since the aftermath of the Fukushima crisis has exposed vulnerabilities in the country's recently liberalised power market, although some of the problems appear self-inflicted.

Power prices in Japan hit record highs last month, mirroring UK peak power prices during tight conditions, as a cold snap across northeast Asia prompted a scramble for supplies of liquefied natural gas (LNG), a major fuel for the country's power plants. Power companies urged customers to ration electricity to prevent blackouts, although no outages occurred.

The crisis highlighted how many providers were unprepared for such high demand. Experts say LNG stocks were not topped up ahead of winter and snow disabled solar power farms, while China's power woes strained solar supply chains.

The hundreds of small power companies that sprang up after the market was opened in 2016 have struggled the most, saying the government does not disclose the market data they need to operate. The companies do not have their own generators, instead buying electricity on the wholesale market.

Prices on the Japan Electric Power Exchange (JEPX) hit a record high of 251 yen ($2.39) per kilowatt hour in January, equating to $2,390 per megawatt hour of electricity, above record European price surges seen recently and the highest on record anywhere in the world. One megawatt hour is roughly what an average home in the U.S. would consume over 35 days.

But the vast majority of the new, smaller companies are locked into low, fixed rates they set to lure customers from bigger players, crushing them financially during a price spike like the one in January.

More than 50 small power providers wrote on Jan. 18 to Japan's industry minister, Hiroshi Kajiyama, who oversees the power sector, asking for more accessible data on supply and demand, reserve capacity and fuel inventories.

"By organising and disclosing this information, retail electricity providers will be able to bid at more appropriate prices," said the companies, led by Looop Co.

They also called on Kajiyama to require transmission and distribution companies to pass on some of the unexpected profits from price spikes to smaller operators.

The industry ministry said it had started releasing more timely market data, and is reviewing the cause of the crunch and considering changes, echoing calls by Fatih Birol to keep electricity options open amid uncertainty.

Japan reworked its power markets after the Fukushima nuclear disaster in 2011, liberalizing the sector in 2016 while pushing for more renewables.

But Japan is still heavily reliant on LNG and coal, and only four of 33 nuclear reactors are operating. The power crisis has led to growing calls to restart more reactors.

Kazuno Power, a small retail provider controlled by a municipality of the same name in northern Japan, where abundant renewable energy is locally produced, buys electricity from hydropower stations and JEPX.

During the crunch, the company had to pay nearly 10 times the usual price, Kazuno Power president Takao Takeda said in an interview. Like most other new providers, it could not pass on the costs, lost money, and folded. The local utility has taken over its customers.

"There is a contradiction in the current system," Takeda said. "We are encouraged to locally produce power for local consumption as well as use more renewable energy, but prices for these power supplies are linked to wholesale prices, which depend on the overall power supply."

The big utilities, which receive most of their LNG on long-term contracts, blamed the power shortfall on a tight spot market and glitches at generation units.

"We were not able to buy as much supply as we wanted from the spot market because of higher demand from South Korea and China, where power cuts have tightened supply," Kazuhiro Ikebe, the head of the country's electricity federation, said recently.

Ikebe is also president of Kyushu Electric Power, which supplies the southern island of Kyushu.

Utilities took extreme measures - from burning polluting fuel oil in coal plants to scavenging the dregs from empty LNG tankers - to keep the grid from breaking down.

"There is too much dependence on JEPX for procurement," said Bob Takai, the local head of European Energy Exchange, where electricity pricing reforms are being discussed, and which started offering Japan power futures last year. He added that new entrants were not hedging against sharp price moves.

Three people, who requested anonymity because of the sensitivity of the matter, were more blunt. One called the utilities arrogant in assuming they could find LNG cargoes in a pinch. Prices were already rising as China snapped up supplies, the sources noted.

"You had volatility caused by people saying 'Oh, well, demand is going to be weak because of coronavirus impacts' and then saying 'we can rely more on solar than in the past,' but solar got snowed out," said a senior executive from one generator. "We have a problem of who is charge of energy security in Japan."

Inventories of LNG, generally about two weeks worth of supplies, were also not topped up enough to prepare for winter, a market analyst said.

The fallout from the crunch has become more apparent in recent days, with new power companies like Rakuten Inc suspending new sales and Tokyo Gas, along with traditional electricity utilities, issuing profit downgrades or withdrawing their forecasts.

Although prices have fallen sharply as temperatures warmed up slightly and more generation units have come back online, the power generator executive said, "we are not out of the woods yet."
