PG&E Bankruptcy Plan outlines wildfire victims compensation via a $13.5B trust funded by cash and stock, aiming CPUC and court approval before June 30 to access the state wildfire insurance fund and finalize settlement.

Key Points

A regulator-approved plan funding a $13.5B wildfire victims trust with cash and PG&E stock to exit bankruptcy.

✅ $13.5B trust split between cash and PG&E shares

✅ Targets CPUC and court approval to meet June 30 deadline

✅ Accesses state wildfire insurance fund for future risks

Pacific Gas & Electric's plan for getting out of bankruptcy has won overwhelming support from the victims of deadly Northern California wildfires ignited by the utility's fraying electrical grid, while some have pursued mega-fire lawsuits through the courts as well, despite concerns that they will be shortchanged by a $13.5 billion fund that's supposed to cover their losses.

The company announced the preliminary results of the vote on Monday without providing a specific tally. Those numbers are supposed to be filed with U.S. Bankruptcy Judge Dennis Montali by Friday.

The backing of the wildfire victims keeps PG&E on track to meet a June 30 deadline to emerge from bankruptcy in time to qualify for a coverage from a California wildfire insurance fund created to help protect the utility from getting into financial trouble again.

The current bankruptcy case, which began early last year, will require PG&E to pay out about $25.5 billion to cover the devastation caused by its neglect, including a Camp Fire guilty plea that underscored liabilities in court proceedings. It's the second time in less than 20 years that PG&E has filed for bankruptcy.

The backing for PG&E's plan isn't a surprise, even though some of the roughly 80,000 wildfire victims had been trying to rally resistance to what they consider to be a deeply flawed plan. The misgivings mostly center on the massive debt that the utility will take on to finance the plan and uncertainties about the fluctuating value of the $6.75 billion in company stock that comprises half of the $13.5 billion promised them.

As it became apparent that the COVID-19 pandemic would drive the economy into a deep recession, PG&E's shares plunged along with the rest of the stock market during March, even as it announced pandemic response measures for customers and employees during that period. That led one financial expert to estimate the PG&E stock earmarked for the wildfire victims' trust would be worth only $4.85 billion, a nearly 30% markdown.

But PG&E's stock price has rebounded in recent weeks and it's now worth more than it was when the deal setting up the victims' trust was struck last December. The shares surged more than 8% to $12.28 in Monday's late afternoon trading. The stock stood at $9.65 when PG&E reached its settlement the wildfire victims.

Critics of the utility's plan also are upset because the company still hasn't specified when the fire victims will be able to sell the shares. It now seems likely the victims will have to hold the stock through the upcoming wildfire season in Northern California, raising the specter that another calamity caused by the utility's badly outdated equipment, as power line fire reports have underscored, could cause the shares to plummet before they can cash out.

A petition signed by more than 3,100 wildfire victims recently urged Gov. Gavin Newsom to consider pushing back the deadline for qualifying for the state's wildfire from June 30 to late August to allow for more time to revise PG&E's plan, as many also turn to a wildfire assistance program for interim aid while they wait. Newsom's office hasn't responded to inquiry about the plan from The Associated Press.

But the lawyers representing the wildfire victims advised their clients to vote in favor of PG&E's plan, contending that it's the best deal they are going to get.

PG&E still must get its plan approved by the judge supervising its case, and a recent judge order on dividend use underscores the focus on wildfire mitigation. The confirmation hearings are scheduled to begin May 27. The judge, though, has indicated he will give great weight to the wishes of the wildfire victims.

California state regulators also must approve PG&E's plan, amid projections that rates will stabilize in 2025 for customers. A vote on that is scheduled Thursday before the Public Utilities Commission.

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Advanced Traffic Light System for Geothermal Safety models fracture growth and friction with rock physics, geophones, and supercomputers to predict induced seismicity during hydraulic stimulation, enabling real-time risk control for ETH Zurich and SED.

Key Points

ATLS uses rock physics, geophones, and HPC to forecast induced seismicity in real time during geothermal stimulation.

✅ Real-time seismic risk forecasts during hydraulic stimulation

✅ Uses rock physics, friction, and fracture modeling on HPC

✅ Supports ETH Zurich and SED field tests in Iceland and Bedretto

The Swiss Earthquake Service and ETH Zurich want to make geothermal energy safer, so news piece from Switzerland earlier this month. This is to be made possible by new software, including machine learning, and the computing power of supercomputers. The first geothermal tests have already been carried out in Iceland, and more will follow in the Bedretto laboratory.

In areas with volcanic activity, the conditions for operating geothermal plants are ideal. In Iceland, the Hellisheidi power plant makes an important contribution to sustainable energy use, alongside innovations like electricity from snow in cold regions.

Deep geothermal energy still has potential. This is the basis of the 2050 energy strategy. While the inexhaustible source of energy in volcanically active areas along fault zones of the earth’s crust can be tapped with comparatively little effort and, where viable, HVDC transmission used to move power to demand centers, access on the continents is often much more difficult and risky. Because the geology of Switzerland creates conditions that are more difficult for sustainable energy production.

Improve the water permeability of the rock

On one hand, you have to drill four to five kilometers deep to reach the correspondingly heated layers of earth in Switzerland. It is only at this depth that temperatures between 160 and 180 degrees Celsius can be reached, which is necessary for an economically usable water cycle. On the other hand, the problem of low permeability arises with rock at these depths. “We need a permeability of at least 10 millidarcy, but you can typically only find a thousandth of this value at a depth of four to five kilometers,” says Thomas Driesner, professor at the Institute of Geochemistry and Petrology at ETH Zurich.

In order to improve the permeability, water is pumped into the subsurface using the so-called “fracture”. The water acts against friction, any fracture surfaces shift against each other and tensions are released. This hydraulic stimulation expands fractures in the rock so that the water can circulate in the hot crust. The fractures in the earth’s crust originate from tectonic tensions, caused in Switzerland by the Adriatic plate, which moves northwards and presses against the Eurasian plate.

In addition to geothermal energy, the “Advanced Traffic Light System” could also be used in underground construction or in construction projects for the storage of carbon dioxide.

Quake due to water injection

The disadvantage of such hydraulic stimulations are vibrations, which are often so weak or cannot be perceived without measuring instruments. But that was not the case with the geothermal projects in St. Gallen 2013 and Basel 2016. A total of around 11,000 cubic meters of water were pumped into the borehole in Basel, causing the pressure to rise. Using statistical surveys, the magnitudes 2.4 and 2.9 defined two limit values ??for the maximum permitted magnitude of the earthquakes generated. If these are reached, the water supply is stopped.

In Basel, however, there was a series of vibrations after a loud bang, with a time delay there were stronger earthquakes, which startled the residents. In both cities, earthquakes with a magnitude greater than 3 have been recorded. Since then it has been clear that reaching threshold values ??determines the stop of the water discharge, but this does not guarantee safety during the actual drilling process.

Simulation during stimulation

The Swiss Seismological Service SED and the ETH Zurich are now pursuing a new approach that can be used to predict in real time, building on advances by electricity prediction specialists in Europe, during a hydraulic stimulation whether noticeable earthquakes are expected in the further course. This is to be made possible by the so-called “Advanced Traffic Light System” based on rock physics, a software developed by the SED, which carries out the analysis on a high-performance computer.

Geophones measure the ground vibrations around the borehole, which serve as indicators for the probability of noticeable earthquakes. The supercomputer then runs through millions of possible scenarios, similar to algorithms to prevent power blackouts during ransomware attacks, based on the number and type of fractures to be expected, the friction and tensions in the rock. Finally, you can filter out the scenario that best reflects the underground.

Further tests in the mountain

However, research is currently still lacking any real test facility for the system, because incorrect measurements must be eliminated and a certain data format adhered to before the calculations on the supercomputer. The first tests were carried out in Iceland last year, with more to follow in the Bedretto geothermal laboratory in late summer, where reliable backup power from fuel cell solutions can keep instrumentation running. An optimum can now be found between increasing the permeability of rock layers and an adequate water supply.

The new approach could make geothermal energy safer and ultimately help this energy source to become more accepted, while grid upgrades like superconducting cables improve efficiency. Research also sees areas of application wherever artificially caused earthquakes can occur, such as in underground mining or in the storage of carbon dioxide underground.

Louisiana Grid Rebuild After Hurricane Laura will overhaul transmission lines and distribution networks in Lake Charles, as Entergy restores power after catastrophic outages, replacing poles, transformers, and spans to stabilize critical electric infrastructure.

Key Points

Entergy's project replacing transmission and distribution in Lake Charles to restore power after the Cat 4 storm

✅ 1,000+ transmission structures and 6,637 poles damaged

✅ Entergy targets first energized line into Lake Charles in 2 weeks

✅ Full rebuild of Calcasieu and Cameron lines will take weeks

The main power utility for southwest Louisiana will need to "rebuild" the region's grid after Hurricane Laura blasted the region with 150 mph winds last week, top officials said.

The Category 4 hurricane made landfall last Thursday just south of Lake Charles near Cameron, damaging or destroying thousands of electric poles as well as leaving "catastrophic damages" to the transmission system for southwest Louisiana, similar to impacts seen during Typhoon Mangkhut outages in Hong Kong that left many without electricity.

“This is not a restoration," Entergy Louisiana president and CEO Phillip May said in a statement. "It’s almost a complete rebuild of our transmission and distribution system that serves Calcasieu and Cameron parishes.”

According to Entergy, all nine transmission lines that deliver power into the Lake Charles area are currently out service due to storm damage to multiple structures and spans of wire.

The transmission system is a critical component in the delivery of power to customers’ homes, and failures at substations can trigger large outages, as seen in Los Angeles station fire outage reported recently, according to the company.

Of those structures impacted, many were damaged "beyond repair" and require complete replacement.

Entergy said the damage in southwest Louisiana includes 1,000 transmission structures, 6,637 broken poles, 2,926 transformers and 338 miles of downed distribution wire, highlighting why proactive reliability investments in Hamilton are being pursued by other utilities.

Some 8,300 workers are now in the area working to rebuild the transmission lines, but Entergy said that it will be about two to three weeks before power is available to customers in the Lake Charles area, a timeline similar to Tennessee outages after severe storms reported recently in other states.

"Restoring power will take longer to customers in inaccessible areas of the region," the company said. "While not impacting the expected restoration of service to residential customers, initial estimates are it will take weeks to rebuild all transmission lines in Calcasieu and Cameron parishes."

Entergy Louisiana expects to energize the first of its transmission lines into Lake Charles in two weeks.

“We understand going without power for this extended period will be challenging, and this is not the news customers want to hear. But we have thousands of workers dedicated to rebuilding our grid as quickly as they safely can to return some normalcy to our customers’ lives,” May said.

According to power outage tracking website poweroutage.us, over 164,000 customers remain without service in Louisiana as of Thursday morning, while a Carolinas outage update shows hundreds of thousands affected there as well.

On Wednesday, the Edison Electric Institute, the association of investor-owned electric companies in the U.S., said in a statement to FOX Business that electricity has been restored to approximately 737,000 customers, or 75% of those impacted by the storm across Louisiana, eastern Texas, Mississippi, and Arkansas, even as utilities adapt to climate change to improve resilience.

At least 29,000 workers from 29 states, the District of Columbia and Canada are working to restore power in the region, according to the Electricity Subsector Coordinating Council (ESCC), which is coordinating efforts from government and power industry.

“The transmission loss in Louisiana is significant, with more than 1,000 transmission structures damaged or destroyed by the storm," Department of Energy (DOE) Deputy Secretary Mark Menezes said in a statement. Rebuilding the transmission system is essential to the overall restoration effort and will take weeks given the massive scale and complexity of the work. We will continue to coordinate closely to ensure the full capabilities of the industry and government are marshaled to rebuild this critical infrastructure as quickly as possible.” 

At least 17 deaths in Louisiana have been attributed to the storm; more than half of those killed by carbon monoxide poisoning from the unsafe operation of generators, and residents are urged to follow generator safety tips to reduce these risks. Two additional deaths were verified on Wednesday in Beauregard Parish, which health officials said were due to heat-related illness following the storm.
