Pacific Gas and Electric Company PG&E recently announced that it has paid a $300 million fine levied by the California Public Utilities Commission CPUC in association with the 2010 natural gas transmission pipeline explosion in San Bruno, California.
When the CPUC announced its decision on April 9, PG&E chose to move forward without an appeal. The payment to the state's General Fund is due Oct. 6. The company recently completed the sale of additional stock necessary to fund the payment.
"We want our customers and their families to know that all of us at PG&E have committed ourselves to a goal of transforming this company into the safest and most reliable energy provider in America. We've made tremendous progress, but we have more to do and we are committed to doing it right," PG&E Corporation Chairman and CEO Tony Earley said.
In addition to the $300 million fine to be paid to the state, the CPUC penalty requires that PG&E shareholders refund $400 million to gas customers and pay $850 million for gas system safety improvements.
The $400 million refund, which will be based on usage, will be returned to customers in early 2016 per the CPUCÂ’s direction.
In addition to the payment to the General Fund, the company has settled claims amounting to more than $500 million with all of the victims and families of the San Bruno accident, established a $50 million trust for the City of San Bruno for costs related to recovery and contributed $70 million to support the city's and community's recovery efforts.
As a result of the concrete actions the company has taken to make safety the cornerstone of its culture following the San Bruno explosion, PG&E became one of the first utilities ever to earn two of the highest internationally recognized safety certifications—the International Organization for Standardization ISO 55001 and Publicly Available Specification PAS 55-1. The company has taken additional actions including the following:
- Change began at the top with Tony Earley joining the company as CEO in 2011. We restructured our gas operations business and hired the best natural gas experts in the country to run it.
- We put 3,500 leaders at all levels of PG&E through safety training and we review the lessons of San Bruno with every new employee.
- We have conducted advanced pipeline safety testing, replaced pipe where necessary and installed more than 200 new automated or remotely controlled emergency shut-off valves.
- We decommissioned more than 800 miles of remaining cast-iron pipe in our system, replacing with stronger, more efficient and seismically sound pipe.
- We built a new gas operations control center, employing the most advanced technology, from which we can monitor the entire system and respond more quickly and effectively to emergencies.
- We're using new gas leak detection technology that is 1,000 times more sensitive than traditional equipment in order to help find and fix leaks before they become a problem. When a customer calls to report a gas odor, we are now among the fastest in the entire industry in responding.
- We have closed out 10 of 12 recommendations from the National Transportation Safety Board and work on the remaining two is on track.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Iran Electricity Exports to Iraq address power shortages and blackouts, supplying 1,200-1,500 MW and gas for 2,500 MW, amid sanctions, aging grid losses, rising peak demand, and TAVANIR plans to expand cross-border energy capacity.
Key Points
Energy flows from Iran supply Iraq with 1,200-1,500 MW plus gas yielding 2,500 MW, easing shortages and blackouts.
✅ 1,200-1,500 MW direct power; gas adds 2,500 MW generation
✅ Iraq exempt on Iranian gas, but faces US pressure
✅ Aging grid loses 25%; $30B upgrades needed
“Iran exports 1,200 megawatts to 1,500 megawatts of electricity to Iraq per day, reflecting broader regional power trade dynamics, as Iraq is dealing with severe power shortages and frequent blackouts,” Hamid Hosseini said.
As he added, Iran also exports 37 million to 38 million cubic meters of gas to the country, much of it used in combined-cycle power plants to save energy and boost generation.
On September 11, Iraq’s electricity minister, Luay al Khateeb, said the country needs Iranian gas to generate electricity for the next three or four years, as energy cooperation discussions continue between Baghdad and Tehran.
Iraq was exempted from sanctions concerning Iranian gas imports; however, the U.S. has been pressing all countries to stop trading with Tehran.
Iraq's population has been protesting to authorities over power cuts. Iran exports 1,200 megawatts of direct power supplies and its gas is converted into 2,500 MW of electricity. According to al Khateeb, the current capacity is 18,000 MW, with peak demand of 25,000 MW possible during the hot summer months when consumption surges, a figure that rises every year.
Any upgrades would need investment of at least $30 billion, with grid rehabilitation efforts underway to modernize infrastructure, as the grid is 50 years old and loses 25 percent of its capacity due to Isis attacks.
In late July, Managing Director of Gharb (West) Regional Electricity Company Ali Asadi said Iran has high capacity and potential to export electricity up to twofold of the current capacity to neighboring Iraq, as it eyes transmitting electricity to Europe to serve as a regional hub as well.
He pointed to the new strategy of Iran Power Generation, Transmission & Distribution Management Company (TAVANIR) for increasing electricity export to neighboring Iraq and reiterated, “the country enjoys high potential to export 1,200 megawatts electricity to neighboring Iraq,” while Iraq is also exploring nuclear power plants to tackle electricity shortages.
Cal ISO Flex Alert urges Southern California energy conservation as a Stage 2 emergency strains the power grid, with potential rolling blackouts during peak hours from 3 to 10 p.m., if demand exceeds supply.
Key Points
A statewide call to conserve power during high demand, issued by the grid operator to prevent rolling blackouts.
✅ Stage 2 emergency signals severe grid strain
✅ Peak Flex Alert hours: 3 to 10 p.m. statewide
✅ Set thermostats to 78 and avoid major appliances
Residents and businesses across Southern California were urged to conserve power Tuesday afternoon amid ongoing electricity inequities across the state as the manager of the state’s power grid warned rolling blackouts could be imminent for some power customers.
The California Independent System Operator (Cal ISO), which manages the state power grid, declared a Stage 2 emergency as of 2:30 p.m., indicating severe strain on the electrical system, similar to a recent grid alert in Alberta that relied on reserves.
ADVERTISING
Rolling blackouts for some customers could occur in a Stage 3 emergency, distinct from the intentional shut-offs some utilities use to reduce wildfire risk.
Cal ISO issued a statewide Flex Alert in effect from 3 to 10 p.m. Tuesday and Wednesday, with conservation considered especially critical during those hours, a concern heightened by pandemic-era grid operations this year.
Officials told reporters rolling blackouts might be avoided Tuesday evening if residents repeat the level of conservation seen Monday.
“If we can get the same sort of response we got yesterday, we can minimize this, or perhaps avoid it altogether,” Cal-ISO President/CEO Steve Berberich said, noting that some operators have even planned staff lockdowns during COVID-19 to maintain reliability.
Cal-ISO controls roughly 80% of the state’s power grid through Southern California Edison, Pacific Gas and Electric Co., with the utility recently restoring power after shut-offs in affected communities, and San Diego Gas & Electric.
Residents are urged to set thermostats at 78 in the afternoon and evening hours and avoiding the use of air conditioning and major appliances during the Flex Alert hours, as utilities like PG&E prepare for winter storms to improve resilience.
Ontario Hydro Rate Relief Plan delivers short-term electricity bill cuts, while leaked cabinet forecasts show inflation-linked hikes, borrowing costs, and a Clean Energy Adjustment under the province's long-term energy plan.
Key Points
A provincial plan that cuts bills now but defers costs, projecting rate hikes and adding a Clean Energy Adjustment.
✅ 25% cut now, after 8% HST relief; extra 17% reduction applied.
✅ Clean Energy Adjustment line to repay deferred system costs.
The short-term gain of a 25 per cent hydro rate cut this summer could lead to long-term pain as a leaked cabinet document forecasts prices jumping again in five years.
In the briefing materials leaked and obtained by the Progressive Conservatives, rates will start rising 6.5 per cent a year in 2022 and top out at 10.5 per cent in 2028, when average monthly bills hit $215.
That would be up from $123 this year once the rate cut — the subject of long-awaited legislation to lower electricity rates unveiled Thursday by Energy Minister Glenn Thibeault — takes full effect. There will be another 17-per-cent cut in addition to the 8 per cent taken off bills in January when the provincial portion of the HST was waived.
The leaked papers overshadowed Thibeault’s efforts to tout the price break, which will be followed with four years of hydro rate increases at 2 per cent, roughly the rate of inflation.
Thibeault charged that the Conservatives used an “outdated” document to distract from the fact that they are the only major party without a plan for dealing with skyrocketing hydro rates, with a year to go until next June’s provincial election.
“It’s not a coincidence,” he told reporters, denying any plans for an eventual 10.5-per-cent rate hike and promising the government’s new long-term energy plan, due in a few months, will have better numbers.
“We are working hard right now to continue to pull costs out of the system.”
Opposition parties said the Liberal plan doesn’t deal with the underlying problems that have made electricity expensive and simply borrows money to spread the costs over a longer period of time, with $25 billion in interest charges over 30 years.
Some observers also noted that a deal with Quebec would not reduce hydro bills, highlighting concerns about lasting affordability.
“The price of electricity is going to skyrocket after the next election,” warned Conservative MPP Todd Smith (Prince Edward—Hastings).
“The government isn’t being honest with the people of Ontario when it comes to the price of electricity.”
The documents show average monthly bills peaking at $231 in the year 2047, before falling back to $210 the following year once the 30 years of interest payments are over.
Conservative sources say they obtained the papers stamped “confidential cabinet document” from a whistleblower after Thibeault’s rate cut plan was presented to cabinet ministers at a meeting in early March.
There is no date on the document, which the energy minister alternately dismissed as “inaccurate” or possibly one of many that have been prepared with different options in mind.
“We’ve had hundreds of briefings with hundreds of documents … I can’t comment on one graph when we’ve been looking at hundreds of scenarios.”
New Democrats, who have proposed a scheme to cut rates, if elected, also called the government plan an election ploy with Liberals lagging in the polls.
“We’re going to take on a huge debt so (Premier) Kathleen Wynne can look good on the hustings in the next few months, and for decades we’re going to pay for it,” said MPP Peter Tabuns (Toronto-Danforth).
Thibeault acknowledged the Liberal plan will start repaying borrowed money in the mid- or late 2020s and it will show up separately on hydro bills as the “Clean Energy Adjustment”, a kind of electricity recovery rate that could raise costs.
EU Energy Price Crisis drives soaring electricity bills as natural gas sets pay-as-clear power prices; leaders debate price caps, common gas purchasing, market reform, renewables, and ETS changes amid Ukraine war supply shocks.
Key Points
A surge in gas-driven power costs linked to pay-as-clear pricing, supply shocks, and policy rifts across the EU market.
✅ Gas sets marginal power price via pay-as-clear mechanism
✅ Spain pushes decoupling and temporary price caps
✅ EU weighs joint gas buying, efficiency, more renewables
Nothing grabs politicians' attention faster than angry voters, and they've had plenty to be furious about as natural gas and electricity bills have soared to stomach-churning levels in recent months, as this UK natural gas analysis illustrates across markets.
That's led to a scramble to figure out ways to get those costs down, with emergency price-limiting measures under discussion — but that's turning out to be very difficult, so the likeliest result is that EU leaders meeting later this week won't come up with any solutions.
“There is no single easy answer to tackle the high electricity prices given the diversity of situations among Member States. Some options are only suitable for specific national contexts,” the European Commission said on Wednesday. “They all carry costs and drawbacks.”
The initial problem was a surge in gas demand in Asia last year coupled with lower-than-normal Russian gas deliveries that left European gas storage at unusually low levels. Now the war in Ukraine is making matters even worse, as pressure grows for the bloc to rapidly cut its imports of Russian oil, coal and natural gas — although some national leaders reject the economic costs that would entail.
"We will end this dependence as quickly as we can, but to do that from one day to the next would mean plunging our country and all of Europe into a recession," German Chancellor Olaf Scholz warned on Wednesday.
The problem for the bloc is that its liberalized electricity market is tightly tied to the price of natural gas; power prices are set by the final input needed to balance demand — called pay-as-clear — which in most cases is set by natural gas. That's led to countries with large amounts of cheaper renewable or nuclear energy seeing sharp spikes in power prices thanks to the cost of that final bit of gas-fired electricity.
A Spanish-led coalition that includes Portugal, Belgium and Italy wants deep reforms to the EU price model, fueling a broader electricity market revamp debate in Brussels.
Others, such as the Netherlands and Germany, strongly oppose such an approach, echoing how nine countries oppose reforms at the EU level, and want to focus on cushioning the effects of the high prices on consumers and businesses, while letting the market operate.
A third group, largely in Central Europe, wants to use the price spike to revamp or scrap the bloc's Emissions Trading System and to rethink its Fit for 55 climate legislation.
The European Commission has been holding the middle ground — arguing that the current market model makes sense, but encouraging countries to boost the amount of renewable electricity, in a wake-up call to ditch fossil fuels for Europe, to cut energy use and increase efficiency.
In draft conclusions of this week's European Council summit, seen by POLITICO, EU leaders, amid a France-Germany tussle over reform, call for things like a common approach to buying gas, aimed at preventing countries from competing against each other. But there's no big movement on electricity prices.
“It does not seem realistic to expect a result on the energy discussion at this European Council,” one diplomat said, stressing that the governments will need to see more analysis before committing to any more steps.
Looking for action Spain wanted a much more robust response. Madrid has been arguing since last summer for “decoupling” gas from the electricity market; together with Portugal, it also mulled limiting the wholesale price of electricity to €180 per megawatt-hour — a proposal that Spain abandoned under fire from industry and consumer groups.
Now Madrid is pushing to get a specific permission in the summit's final conclusions that would allow countries to voluntarily apply certain short-term solutions such as gas price cap strategies, according to a draft with track changes seen by POLITICO.
The issue with a cap is if gas prices are higher than the cap, Spain might not be able to buy any gas.
DARPA RADICS Power Grid Security targets DoD resilience to cyber attacks, delivering early warning, detection, isolation, and characterization tools, plus a secure emergency network to protect critical infrastructure and speed grid restoration and communications.
Key Points
A DoD/DARPA initiative to detect, contain, and rapidly recover the U.S. grid from sophisticated cyber attacks.
✅ Early warning separates attacks from routine outages
✅ Pinpoints intrusion points and malware used
✅ Builds secure emergency network for rapid restoration
The U.S. Department of Defense is growing increasingly concerned about hackers taking down our power grid and crippling the nation, reflecting a renewed focus on grid protection across agencies, which is why the Pentagon has created a $77-million security plan that it hopes will be up and running by 2020.
The U.S. power grid is threatened every few days. While these physical and cyber attacks have never led to wide-scale outages, attacks are getting more sophisticated. According to a 494-page report released by the Department of Energy in January and a new grid report card, the nation’s grid “faces imminent danger from cyber attacks.” Such a major, sweeping attack could threaten “U.S. lifeline networks, critical defense infrastructure, and much of the economy; it could also endanger the health and safety of millions of citizens.” If it were to happen today, America could be powered-down and vulnerable for weeks.

The DoD is working on an automated system to speed up recovery time to a week or less — what it calls the Rapid Attack Detection, Isolation, and Characterization (RADICS) program. DARPA, the Pentagon’s research arm, originally solicited proposals in late 2015, asking for technology that did three things. Primarily, it had to detect early warning signs and distinguish between attacks and normal outages, especially after intrusions at U.S. electric utilities underscored the risk, but it also had to pinpoint the access point of the attack and determine what malicious software was used. Finally, it must include an emergency system that can rapidly connect various power-supply centers, without any human coordination. This would allow emergency and military responders to have an ad hoc communication system in place moments after an attack.
“If a well-coordinated cyberattack on the nation’s power grid were to occur today, the time it would take to restore power would pose daunting national security challenges,” said DARPA program manager John Everett, in a statement, at the time. “Beyond the severe domestic impacts, including economic and human costs, prolonged disruption of the grid would hamper military mobilization and logistics, impairing the government’s ability to project force or pursue solutions to international crises.”
DARPA plans to spend $77 million on RADICS, while DOE funding to improve the grid complements these initiatives. Last November, SRI International announced it had received $7.3 million from the program. In December, Raython was granted $9 million. The latest addition is BAE Systems, which received $8.6 million last month to develop technology that detects and contains power-grid threats, and creates a secure emergency provisional system that restores some power and communication in the wake of an attack — what is being called a secure emergency network.
According to the military news site Defense Systems, BAE’s SEN would rely on radio, satellite, or wireless internet — particularly as ransomware attacks continue to rise — whatever is available that allows the grid to continue working. The SEN would serve as a wireless connection between separate power grid stations.
While the ultimate goal of the RADICS program will be the restoration of civilian power and communications, the SEN will prioritize communication networks that would be used for defense or combat, so the U.S. government can still wage war while the rest of us are in the dark.
