Tesla Energy to power SoCal through world’s largest lithium-ion battery storage project
Tesla Energy has announced that the company has been selected by Southern California Edison to provide a 20-Megawatt Powerpack system to the Mira Loma substation. According to the Silicon Valley energy company, the system will be the world’s largest lithium ion battery storage project when complete, and will be capable of powering more than 2,500 households for a day and charge 1,000 Teslas
Cells for the Powerpack commercial-grade energy storage unit will be produced at the company’s Gigafactory plant in Sparks, Nevada. Tesla says through its blog post, “The Gigafactory’s ability to produce at a large scale will allow this system to be manufactured, shipped, installed and commissioned in three months. The system will charge using electricity from the grid during off-peak hours and then deliver electricity during peak hours to help maintain the reliable operation of Southern California Edison’s electrical infrastructure which feeds more than 15 million residents.”
The project comes after a methane gas spill took place at Aliso Canyon in Southern California last October. Over 8,000 Californians were displaced after 1.6 million pounds of methane leaked into the atmosphere as a result of a rupture in the natural gas reservoir. Soon after the Governor of California declared a state of emergency, the state’s utilities commission spawned a project that would ultimately see an energy storage solution for LA. Tesla won the bid to provide an 20MW/80MWh battery storage solution that would allow utility companies to off load energy generation from off-peak hours to times of peak demand when electricity needs can be bursty.
Addressing Peak Energy Demand with the Tesla Powerpack
Last October, a catastrophic rupture in the Aliso Canyon natural gas reservoir caused a methane gas spill that displaced more than 8,000 Californians and released an unprecedented 1.6 million pounds of methane into the atmosphere. Today, the Aliso Canyon leak is considered the worst in U.S. history, with aggregate greenhouse gas emissions said to outweigh those of the 2010 Deepwater Horizon oil spill.
Following the disaster, authorities closed the Aliso Canyon facility, which had been feeding the network of natural gas peaker plants in the Los Angeles basin, deeming it unfit to store the fuel safely and environmentally.
One year later, Los Angeles is still in need of an electric energy solution that ensures reliability during peak times. As winter approaches, homes and buildings in the basin will need more natural gas for heat. These demands apply uncharacteristically high pressure to the energy system, exposing the Los Angeles basin to a heightened risk of rolling blackouts.
Following the leak, California Governor Jerry Brown issued a state of emergency, and in May, the California Public Utilities Commission mandated an accelerated procurement for energy storage. Southern California Edison, among other utilities, was directed to solicit a utility-scale storage solution that could be operational by December 31, 2016. Unlike traditional electric generators, batteries can be deployed quickly at scale and do not require any water or gas pipelines.
Last week, through a competitive process, Tesla was selected to provide a 20 MW/80 MWh Powerpack system at the Southern California Edison Mira Loma substation. Tesla was the only bidder awarded a utility-owned storage project out of the solicitation.
Upon completion, this system will be the largest lithium ion battery storage project in the world. When fully charged, this system will hold enough energy to power more than 2,500 households for a day or charge 1,000 Tesla vehicles.
The Gigafactory’s ability to produce at a large scale will allow this system to be manufactured, shipped, installed and commissioned in three months. The system will charge using electricity from the grid during off-peak hours and then deliver electricity during peak hours to help maintain the reliable operation of Southern California Edison’s electrical infrastructure which feeds more than 15 million residents. By doing so, the Tesla Powerpack system will reduce the need for electricity generated by natural gas and further the advancement of a resilient and modern grid.
In order to achieve a sustainable energy future, one which has high penetration of solar and electric vehicles, the world needs a two-way, flexible electric grid. The electric power industry is the last great industry which has not seen the revolutionary effects of storage. Working in close collaboration with Southern California Edison, the Tesla Powerpack system will be a landmark project that truly heralds the new age of storage on the electric grid.
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
