Slashdot readers MojoKid and williamyf share the news of AMD's two new high-end graphics cards, the Radeon RX 7900 XTX and 7900 XT. "Priced at $999 and $899 respectively and available in December this year, the new Radeon cards are expected to go toe-to-toe with NVIDIA's GeForce RTX 4080 and 4090," writes MojoKid. HotHardware reports: AMD states that its goals for RDNA 3 are to accelerate performance-per-watt leadership and to raise the bar for high resolution and high framerate gaming. AMD has turned to a chiplet architecture to accomplish these goals, a first for gaming GPUs. The chiplet complexes consist of a 5nm graphics compute die (GCD), which is flanked top and bottom by up to six 6nm memory and cache dice (MCD). The RX 7900 XTX uses the full complement of 6 MCDs which aggregates as a 384-bit memory bus (64-bit per die) with GDDR6 memory offering 20Gbps of throughput. The RX 7900 XT uses 5 MCDs with a corresponding 320-bit bus.

All of this increased bandwidth and resources translates to what AMD claims is up to a 1.7X uplift in performance for the Radeon RX 7900 XTX versus its previous gen Radeon RX 6950 XT card in high resolution gaming. This could put the card within striking distance of NVIDIA's GeForce RTX 4090 possibly, but it's hard to say until cards ship to independent reviewers for testing. Regardless, gamers will appreciate the RX 7900 XTX's price point versus NVIDIA's $1600 top-end beast.

Saudi Arabia's sovereign wealth said on Thursday it will make electric cars in the kingdom under a joint venture with Apple supplier Foxconn as part of a push to build new industries and lessen dependence on oil. Reuters reports: Ceer "is the first Saudi automotive brand to produce electric vehicles in Saudi Arabia, and will design, manufacture and sell a range of vehicles for consumers in Saudi Arabia and the MENA (Middle East and North Africa) region, including sedans and sports utility vehicles," PIF said in a statement. PIF said its cars would be available in 2025, adding Ceer would draw more than $150 million in foreign direct investment, create up to 30,000 direct and indirect jobs and is projected to contribute $8 billion to the kingdom's GDP by 2034.

The joint venture "will license component technology from BMW for use in the vehicle development process," PIF said in a statement. "Foxconn will develop the electrical architecture of the vehicles, resulting in a portfolio of products that will lead in the areas of infotainment, connectivity and autonomous driving technologies," it added.

China's government-owned utility State Power Investment Corporation (SPIC) has launched the world's first commercial offshore floating solar that's paired with an offshore wind turbine. Electrek reports: SPIC is one of five major electrical utility companies in China, and the world's largest photovoltaic power generation enterprise. The pilot is located off the coast of Haiyang, a city in Shandong, eastern China. The project uses Norway-based Ocean Sun's patented floating solar power technology. The two solar floaters (see the photo above) have an installed capacity of 0.5 megawatts peak. They're connected to a transformer on a SPIC-owned wind turbine and then a subsea cable runs from the wind turbine to the power grid. If the pilot is successful, the plan is to build a 20 MW floating wind-solar farm in 2023 using Ocean Sun's technology.

The Chinese Navy could finally use lithium technology to replace the lead-acid batteries that are now used in its fleet of conventional submarines. Interesting Engineering reports: Since lithium batteries had a higher risk of catching fire or exploding, the navy was hesitant to replace the submarine fleet's current batteries with them. But, "after solving these problems, the replacement of lead-acid batteries with lithium batteries in conventional submarines is just around the corner," said Wang Feng, study lead and a submarine designer. The study claims that technical answers have been discovered through significant testing and development in China's electric car sector, and lithium batteries have been demonstrated to operate safely under difficult circumstances. The modifications could considerably improve a submarine's capacity for survival and battle, according to research that was released on October 15 in the peer-reviewed Chinese journal Marine Electric and Electronic Engineering.

For more than a decade, the Chinese military has planned to replace the lead-acid batteries in its fleet of conventional submarines with lithium technology. The lead-acid batteries on these submarines, which have not seen significant development since World War II, have proved problematic due to their poor energy storage capacity, delayed charging, limited power output, short lifespan, and harmful gas leaks, according to the paper. Nickel and cobalt, which are added to batteries to increase performance, were a contributing factor to mishaps; however, some Chinese battery manufacturers have begun using iron and phosphate in their place recently.

Apple's next group of Macs probably won't launch until early next year, Bloomberg News reports, which means it will have fewer new devices to sell in the holiday quarter. From the report: Apple has been gearing up to launch a slew of new Macs, and now we have a clearer idea of when that will occur: early next year. I'm told that Apple is aiming to introduce the upgraded models -- including M2-based versions of the 14-inch and 16-inch MacBook Pros -- in the first quarter of calendar 2023 and has tied the launches to the upcoming macOS Ventura 13.3 and iOS 16.3. Those software updates are expected to debut between early February and the beginning of March.

[...] The new MacBook Pros will continue to look like the current models, but they'll trade their M1 Pro and M1 Max chips for the first M2 Pro and M2 Max processors. The M2 Max will go to 12 CPU cores, up from 10, and see its top graphics option move to 38 cores from 32. A new Mac mini remains in development, and the company continues to test versions with the same M2 chip as the 13-inch MacBook Air and MacBook Pro, as well as an M2 Pro chip, which hikes the CPU and graphics counts. If Apple indeed launches the M2 Pro variation, we can expect the company to probably wind down the still-available Intel model.

"Four times a week on average, an e-bike or e-scooter battery catches fire in New York City," reports NPR: Sometimes, it does so on the street, but more often, it happens when the owner is recharging the lithium ion battery. A mismatched charger won't always turn off automatically when the battery's fully charged, and keeps heating up. Or, the highly flammable electrolyte inside the battery's cells leaks out of its casing and ignites, setting off a chain reaction.

"These bikes when they fail, they fail like a blowtorch," said Dan Flynn, the chief fire marshal at the New York Fire Department. "We've seen incidents where people have described them as explosive — incidents where they actually have so much power, they're actually blowing walls down in between rooms and apartments."

And these fires are getting more frequent.

As of Friday, the FDNY investigated 174 battery fires, putting 2022 on track to double the number of fires that occurred last year (104) and quadruple the number from 2020 (44). So far this year, six people have died in e-bike-related fires and 93 people were injured, up from four deaths and 79 injuries last year.

Fierce Electronics reports on "a complex legal battle in U.S. district court" between Qualcomm and Arm "over licensing of intellectual property with potentially far-reaching impact..." Normally, Arm licenses its architectural designs and related IP to chipmakers such as Nvidia or Qualcomm, which in turn produce chips that are then sold to OEMs that use those chips to make servers and other computers and devices. In an updated Qualcomm counterclaim made public Oct. 26, Qualcomm argues that Arm is no longer going to license its CPU designs after 2024 to Qualcomm and other chip companies under technology license agreements. Instead, Qualcomm asserts, Arm will only license to a broad array of device makers....

Arm has not yet formally responded to Qualcomm's latest counterclaim but told Fierce Electronics via email on Friday that Qualcomm's complaint is "riddled with inaccuracies" that Arm will address in a formal legal response in coming weeks....

[Analyst] Dylan Patel in SemiAnalysis also said the counterclaim shows Arm is not planning to allow external GPUs, NPUs or ISPs in Arm-based SoCs. "It seems that Arm is effectively bundling its other IP with the CPU IP in a take-it-or-leave-it model," Patel said. "That would mean Samsung's licensing deal with AMD for GPU or Mediatek with Imagination GPU is not longer allowed after 2024...." Qualcomm argues Arm is making it clear to the marketplace that "it will act recklessly and opportunistically, threatening the development of new and innovative products as a negotiating tactic, not because it has valid license and trademark claims."
Again, Arm has called Qualcomm's complaint "riddled with inaccuracies." Jack Gold, an analyst at J. Gold Associates, tells Fierce Wireless that If Qualcomm's counterclaim is accurate, "this is a troubling step for the industry." If Arm were to get rid of tech licensing as described by Qualcomm, it would give rise to RISC-V use, something Arm "should be worried about," Gold said....

[Analyst] Patel has also questioned if Arm's original lawsuit is more than just about money and might be because Softbank (owner of Arm) and Arm remain angry that Qualcomm, as Patel puts it, worked with regulators to block Nvidia's $40 billion acquisition of Arm. After working for more than a year to seal the deal, Nvidia and SoftBank announced the termination of the proposed deal on Feb. 7, 2022, due to "significant regulatory challenges." Arm was expected to go public within a year, but an IPO has not occurred as of late October.

An anonymous reader quotes a report from The Register: AMD turned to advanced packaging to create chiplet designs and become a formidable CPU player again. Apple used the tech to beef up the power of its M1 Ultra chip. And Intel is pinning its future success on 2D and 3D multi-die packaging technologies as part of its ambitious comeback plan. Now TSMC, the world's largest contract chipmaker, wants to make chiplet-based products easier and faster to manufacture using its growing toolbox of advanced packaging tech that has already benefited the likes of AMD, Apple, and others. The Taiwanese foundry giant plans to do this through the formation of the 3DFabric Alliance, announced Thursday, which aims to help chip designers implement advanced packaging tech into their plans faster by collaborating with partner companies that are key to the development process.

TSMC's partners cover several important elements of chip development, from electronic design automation and memory to substrates and testing. As part of the new alliance, they will have early access to TSMC's 3DFabric portfolio of 3D silicon stacking and advanced packaging technologies. The goal is to allow these partners to build new solutions in parallel with the development of TSMC's 3DFabric tech so that chip designers can get their hands on the tools, technologies, materials, and other resources necessary to make multi-die chip packages faster. TSMC's 3DFabric portfolio includes brand-new technology, like system-on-integrated-chips (SoIC), which underpins the 3D V-Cache tech in AMD's Milan-X and Ryzen 7 5800X3D processors that came out this year. The portfolio also includes older technologies: integrated-fan-out and chip-on-wafer-on-substrate (CoWoS), which have received new iterations over the past several years. Those using CoWoS include Nvidia and Amazon Web Services. Representatives from AMD, Nvidia, and AWS gave support for the new alliance, which is one of several set up by TSMC as part of its Open Innovation Platform initiative. TSMC veep of R&D, LC Lu, said while advanced packaging technologies can "open the door to a new era of chip-level and system-level innovation," "extensive ecosystem collaboration" is required to "help designers navigate the best path through the myriad options and approaches available to them."

"Through the collective leadership of TSMC and our ecosystem partners, our 3DFabric Alliance offers customers an easy and flexible way to unlocking the power of 3D [integrated circuits] in their designs," he added.

China plans to break its own record for the world's largest wind farm by constructing a new one before 2025 that could power more than 13 million homes. Interesting Engineering reports: The 14th five-year plan for Chaozhou, China's Guangdong province, was released last week, outlining the city's ambitious plans for a 43.3 gigawatt (GW) project in the Taiwan Strait. Work on the project will begin "before 2025." It will surpass the largest wind farm in the world once it is finished, according to Guangdong province officials. The 10-kilometer-long farm, which will have thousands of strong wind turbines, will operate between 75 and 185 kilometers (47 and 115 miles) offshore. And because of the region's distinctive topographical features and windy location, these turbines will be able to run between 43 percent to 49 percent of the time, meaning 3,800 to 4,300 hours each year.

A gigawatt is one billion watts, and 3 million solar panels are required to produce one gigawatt of power. 100 million LEDs or 300,000 typical European homes may each be powered by one gigawatt. The facility's 43.3 GW of power-generating capacity could supply electricity to 13 million households, which is equal to 4.3 billion LED lights, as per Euronews. The Jiuquan Wind Power base in China, a huge facility with a 20 gigawatt capacity, presently holds the distinction of being the world's largest wind farm.

Nearly six years after the Pebble smartwatch was purchased by Fitbit and discontinued, a new Pebble app for Android has been released by the Rebble Alliance, a group that has kept Pebble viable for its users since Fitbit shut down Pebble's servers in mid-2018," writes Ars Technica's Kevin Purdy. "Pebble version 4.4.3 makes the app 64-bit so it can work on the mostly 64-bit Pixel 7 and similar Android phones into the future. It also restores a caller ID function that was hampered on recent Android versions." From the report: Most notably, the app is "signed using the official Pebble keys," with Google Fit integration maintained, but isn't available through Google's Play Store. Google acquired Fitbit for $2.1 billion, making it the steward of Pebble's remaining IP and software pieces. Katharine Berry, a key Rebble coder and leader, works on Wear OS at Google and was one of the first to tweet news of the new update, "four years after 4.4.2." That was the last Play Store update to the Pebble app from Pebble developers, one that freed up many of the app's functions to be replaced by independent servers.

That's exactly where Rebble picked up, providing web services to Pebble watches, including (for paying subscribers) voice dictation. But those services still relied on the core Pebble app to connect the watch and smartphone. If Android did make the leap to a 64-bit-only OS, it could have left Pebble/Rebble users in the lurch. Berry's post on r/pebble offers "thanks to Google for providing us with one last update!" This is, to be sure, not the typical outcome of products that have been acquired by Google, even if second-hand.

A Redditor says they've managed to get a hold of an old Netflix server for free, and has posted a detailed online look at the once mysterious hardware. The devices were part of Netflix's Open Connect Content Delivery Network (CDN), and can often be found embedded within major ISP networks to ensure your Netflix streams don't suck. From a report: Reddit user PoisonWaffle3 said the ISP he currently works for has been offloading old Netflix servers as they upgrade to more modern equipment. In a Reddit thread titled "So I got a Netflix cache server..." he posted a photo of the server, which is bright Netflix red, and explained how he was curious about what's inside the boxes given how little public information was available.

"All I could find online was overviews, installation/config guides for their proprietary software, etc.," he said. "No specs, no clue what was inside the red box." Dave Temkin, Netflix's former Vice President of Network Systems Infrastructure told Motherboard there's nothing too mysterious about what the servers can do, though they significantly help improve video streaming by shortening overall content transit time. "They're just an Intel FreeBSD box," he said. "We got Linux running on some of the generations of that box as well."

Netflix's Open Connect Content Delivery Network hardware caches popular Netflix content to reduce overall strain across broadband networks. Netflix lets major broadband ISPs embed a CDN server on the ISP network for free; the shorter transit time then helps improve video delivery, of benefit to broadband providers and Netflix alike. It took all of three screws for PoisonWaffle3 to get inside the mysterious red unit, at which point users discovered a "fairly standard" Supermicro board, a single Xeon E5 2650L v2 processor, 64GB of DDR3 memory, and a 10 gigabit ethernet card. They also found 36 7.2TB 7200RPM drives and six 500GB Micron solid state drives, for a grand total of 262 terabytes of storage.

From Tokyo to San Francisco, mobile game studios have sparred for years to captivate a fickle audience, fostering an overlooked problem -- the average title has become so huge that players can no longer fit more than a few on their phones. From a report: Japanese games publisher Gree expects an impending reckoning over escalating costs and ballooning file sizes, as developers pack their games with increasingly intricate graphics, voice acting and larger storylines, all to get players spending. That's creating a winner-takes-all situation that could winnow out smaller studios in coming years, Gree Senior Vice President Yuta Maeda said in an interview. The situation will only get worse as console veteran Sony -- no stranger to space-hogging hits -- prepares to invade the mobile arena. "Production of mobile games can't avoid becoming more complex, time-consuming and larger-scale, which will inevitably result in bigger app sizes," Maeda said. "Companies that survive in the market will only be the ones that can keep up with that trend."

The spending poured into today's A-list mobile titles -- MiHoYo's Genshin Impact, for instance, started with a $100 million budget -- rivals Hollywood blockbusters and is yielding better production values than ever, but also an outsized footprint. That game can occupy upwards of 20 gigabytes of storage, which is a huge chunk of what most people have available on their phones. With memory upgrades not keeping pace, the result is fewer games can vie for attention. Sony, one of the giants of console gaming, has laid out plans to bring its high-profile PlayStation franchises to mobile platforms. Rival Microsoft is also building an Xbox mobile gaming store. All of that piles pressure on the entrenched free-to-play business model followed by Gree and others. These publishers rely on monetizing in-game items and upgrades, regularly adding more content players can buy and play with. The most common workaround from game studios is to put only a basic installer in app stores, which then downloads further game assets once the player starts. Gree uses it with Heaven Burns Red, which is an initial 1GB and grows beyond 10GB for players who want the full experience.

Memtest86+ just got its first update after 9 years. The program has reportedly been rewritten from scratch and is back in active development. The new version, 6.0, features a plethora of updates to bring the application up to date, and support the latest system hardware from Intel and AMD. Tom's Hardware reports: For the uninitiated, MemTest86 was originally created back in the mid 1990s, and was one of the earliest DDR memory testing applications for personal computers. But development stopped in 2013 once Memtest86 was split into Memtest86 and Memtest86", with the former being bought by PassMark. Officially, we don't know why development stopped. But compared to the now modern Memtest86, Memtest86+ is the open-source variant.

Needless to say, version 6.00 features a lot of updates, which were required to bring it up to modern standards compared to the 2013 version. The new version includes completely rewritten code for UEFI-based motherboards, the modern version of a BIOS, for both 32-bit and 64-bit versions of the application. Furthermore, the application features added support for x64 long mode paging, support for up to 256 cores, added detection for DDR4 and DDR5 memory -- since DDR3 was the latest memory standard in 2013 -- and adds support for XMP version 3.0.

CPU support has been significantly enhanced, addingdetection for all pre-Zen and AMD Zen-based processors ranging from the Ryzen 1000 series to 7000 series, and any older parts that were made after 2013. Intel support has also been added for chips up to 13th gen Raptor Lake. Finally, the last patch notes indicate version 6.0 adds support for older Nvidia and AMD chipsets - probably pre-2010 since it mentions Nvidia nForce chipsets, along with numerous bug fixes, optimizations and enhancements.

"Linus Torvalds has backed the idea of possibly removing Intel 486 (i486) processor support from the Linux kernel," reports Phoronix: After the Linux kernel dropped i386 support a decade ago, i486 has been the minimum x86 processor support for the mainline Linux kernel. This latest attempt to kill off i486 support ultimately arose from Linus Torvalds himself with expressing the idea of possibly requiring x86 32-bit CPUs with "cmpxchg8b" support, which would mean Pentium CPUs and later:

Maybe we should just bite the bullet, and say that we only support x86-32 with 'cmpxchg8b' (ie Pentium and later).

Get rid of all the "emulate 64-bit atomics with cli/sti, knowing that nobody has SMP on those CPU's anyway", and implement a generic x86-32 xchg() setup using that try_cmpxchg64 loop.

I think most (all?) distros already enable X86_PAE anyway, which makes that X86_CMPXCHG64 be part of the base requirement.

Not that I'm convinced most distros even do 32-bit development anyway these days.... We got rid of i386 support back in 2012. Maybe it's time to get rid of i486 support in 2022?
Towards the end of his post, Torvalds makes the following observation about i486 systems. "At some point, people have them as museum pieces. They might as well run museum kernels. "

Iran has one nuclear power plant. The email system of the company operating it was just breached, according to Iran's civil nuclear arm. The Associated Press reports: An anonymous hacking group claimed responsibility for the attack on Iran's Atomic Energy Organization, demanding Tehran release political prisoners arrested in the recent nationwide protests. The group said it leaked 50 gigabytes of internal emails, contracts and construction plans related to Iran's Russian-backed nuclear power plant in Bushehr and shared the files on its Telegram channel. It was unclear whether the breached system contained classified material.

The hack comes as Iran continues to face nationwide unrest...

"It might be a while before you can buy a 'Roomba for laundry'," jokes Slashdot reader Tony Isaac, pointing out that "while robots have been developed that can fold specific types of laundry, there's still not a good robot that can do the job quickly, or for all types."

But NPR reports laundry-folding robots are getting closer: As NPR has reported, machines need clear rules in order to function, and it's hard for them to figure out what exactly is going on in those messy piles That's not to say that it's completely impossible. University of California, Berkeley professor Pieter Abbeel spent years teaching a robot how to fold a towel, eventually cutting that process down from 20 minutes to a whopping minute and a half.

And Silicon Valley-based company FoldiMate raised hopes and eyebrows when it showed off a prototype of its eponymous laundry-folding robot at the Consumer Electronics Show in early 2019. It said the machine could fold some 25 pieces of laundry — except for small items like socks and large items like sheets — in under five minutes, with an estimated price tag of $980. It's unclear what happened to that company — its website is down and it hasn't tweeted since April 2020. Its sole competitor, a Japanese company with an AI-powered prototype, filed for bankruptcy.

In sum, most robots have not generally been equipped for the task. But an international group of researchers say their new method could change that — or at least speed up the process. Researchers are calling the new method, SpeedFolding. It's a "reliable and efficient bimanual system" — meaning it involves two hands — that's able to smooth and fold a crumpled garment in record speed (for robots, that is). SpeedFolding can fold 30 to 40 strewn-about garments per hour, compared to previous models that averaged three to six garments in that same time span, according to researchers. They say their robot can fold items in under two minutes, with a success rate of 93%.

"Real-world experiments show that the system is able to generalize to unseen garments of different color, shape, and stiffness," they add.
According to the article, the team will be presenting their paper at a robotics conference in Kyoto this month, and they've also posted a one-minute video on YouTube. (Their solution involves both an overhead camera and a novel neural network called BiManual Manipulation Network that "studied 4,300 human and machine-assisted actions in order to learn how to smooth and fold garments from a random configuration."

"While researchers describe SpeedFolding as a significant improvement, it's not likely to hit the market anytime soon," notes NPR. "For one, Ars Technica tracked down a robot similar to the one they used and found that it retails for $58,000."

IEEE Spectrum reports that "Standard electric-vehicle batteries can recharge much of their range in just 10 minutes with the addition of a thin sheet of nickel inside them, a new study finds." This could provide a welcome and economically attractive alternative to expensive EVs that carry massive and massively expensive battery packs. If faster-charging options were available, enabling the EV's sticker price to drop substantially, some researchers suspect consumers' EV phobia and industry dogma against "range anxiety" could be overcome....

In the new study, researchers experimented with a lithium-ion battery with a roughly 560-kilometer range when fully charged. (The battery's energy density was 265 watt-hours-per-kilogram.) By adding an ultrathin nickel foil to its interior [to heat the battery quickly], they could recharge it to 70 percent in 11 minutes for a roughly 400-km range, and 75 percent in 12 minutes for a roughly 440-km range.

"Our technology enables smaller, faster-charging batteries to be deployed for mass adoption of affordable electric cars," says study senior author Chao-Yang Wang, a battery engineer at Pennsylvania State University....

The scientists detailed their findings online in the journal Nature.

"Farmers have urged whoever succeeds Liz Truss as UK prime minister to abandon plans to ban solar energy from most of England's farmland," reports the Guardian, "arguing that it would hurt food security by cutting off a vital income stream." Truss, who resigned on Thursday, and her environment secretary, Ranil Jayawardena, hoped to ban solar from about 41% of the land area of England, or about 58% of agricultural land, the Guardian revealed last week. They planned to do this by reclassifying less productive farmland as "best and most valuable", making it more difficult to use for energy infrastructure.

Members of the Country Land and Business Association (CLA), which represents 33,000 landowners, told the Guardian having solar on their less productive land allowed them to subsidise food production during less successful years, as well as providing cheap power for their estates and homes in their local area.
One farmer made the case succinctly to the Guardian. "We make unequivocally more from our solar panels than from farming."

Hardcore overclocker Elmor "officially broke the CPU frequency world record with Intel's brand-new Core i9-13900K 24-core processor," reports Tom's Hardware — by hitting "a staggering 8.812GHz using liquid nitrogen cooling, dethroning the 8-year reigning champion, the FX-8370, by 90MHz." That's right; it took eight years for a new CPU architecture to dethrone AMD's FX series processors. Those chips are infamous for their mediocre CPU performance at launch; however, these chips scaled incredibly well under liquid nitrogen overclocking....

Elmor accomplished this monumental feat thanks to Intel's new highly-clocked 13th Gen Raptor Lake CPU architecture. Out of the box, the Core i9-13900K can run over 5.5GHz on all P-cores while also hitting 5.8GHz under lightly threaded workloads. The 13900K is, by far, Intel's highest-clocking chip to date.

Meet Crimson Storage, the world's largest single-phase battery, which is now live in the California desert. Electrek reports: Crimson Storage is also the second-largest energy storage project currently in operation of any configuration. The 350 megawatt (MW)/1400 megawatt-hour (MWh) battery storage project, which sits on on 2,000 acres west of Blythe in Riverside County, broke ground in 2021. Canadian Solar oversaw construction and provided the battery energy storage systems, and Axium Infrastructure and solar and storage developer Recurrent Energy will be Crimson Storage's long-term owners.

Residential homes are usually served by a single-phase power supply, and this project, on average, is expected to store and dispatch enough electricity to power more than 47,000 homes each year. Crimson Storage holds two long-term contracts with local utilities: a 200 MW/800 MWh 14-year and 10-month contract with Southern California Edison, and a 150 MW/ 600MWh 15-year contract with Pacific Gas and Electric.
