Installation of large-scale energy storage systems is expected to continue increasing in the U.S. throughout 2024, as championed by only a handful of states thus far.

According to data from the Energy Information Administration (EIA) shared on Tuesday, U.S. energy storage system deployment is expected to nearly double in 2024, with battery capacity forecasted to grow by 89 percent. As of November 2023, two U.S. states have installed substantially more energy storage systems than others, making up the vast majority of battery capacity available.

The data shows that California leads energy storage availability by a wide margin, with just over 7.3 GW (7,302 MW) of battery capacity installed. Texas follows in second with nearly 3.2 GW (3,167 MW) installed, while Arizona, Florida, and Massachusetts are next in the lineup.

The data takes into account planned storage system projects for the next two years, and the agency says developers are aiming to expand U.S. storage capacity by 30 GW by the end of 2024. As the EIA also notes, U.S. battery storage capacity has been increasing since 2021, and if the aforementioned goal is achieved, the country will have more energy storage than petroleum liquids, geothermal, wood and wood waste, or landfill gas by the end of this year.

There are over 300 utility-scale battery storage projects planned to be brought online by 2025, with roughly half of them being in Texas. Currently, the largest operating battery energy storage system (BESS) is a project operated by Vistra in Moss Landing, California, which has 750 MW of capacity and is located not far from Tesla’s 182.5 MW Megapack site in the same city.

Four out of five of the largest BESS installations set to take place in 2024 or 2025 are in Texas, as listed below:

  • Lunis Creek BESS SLF (Texas, 621 MW)
  • Clear Fork Creek BESS SLF (Texas, 600 MW)
  • Hecate Energy Ramsey Storage (Texas, 500 MW)
  • Bellefield Solar and Energy Storage Farm (California, 500 MW)
  • Dogwood Creek Solar and BESS (Texas, 443 MW)

As for the recent increases in storage capacity, the agency says that quickly increasing wind and solar generation fleets in California and Texas have increased the need for growth in the battery storage sector. With energy storage projects, utility operators are able to store power during times of low electricity demand and then deploy stored energy during times of peak demand.

The news comes just a few days after Tesla Megapacks went live on the island of Oahu in Hawaii, enabling a 185 MW project that has helped the island move away from the use of coal. The project isn’t represented in the EIA’s dataset, since that data only accounts for installations through last November.

In addition to its grid-scale Megapacks, Tesla also offers smaller, residential-level Powerpacks to create what it calls Virtual Power Plants (VPPs), essentially forming giant, distributed batteries that customers can use to sell energy back to the grid in times of peak demand. Currently, Tesla has pilots for these programs in states including California, Texas and Massachusetts, along with the U.S. territory of Puerto Rico.

Elon Musk teases TSMC as potential Terafab partner

Published

Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.

Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.

The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.

Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.

Elon Musk’s Terafab project locks up massive new partner

Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.

Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.

Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.

Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.

If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.

Tesla reveals early Robotaxi charging strategy, showing scrappy DNA

Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.

An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.

On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.

However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.

Tesla Robotaxi expands hours, Musk explains why it’s been a challenge

Published

Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.

CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.

The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.

Tesla Robotaxi will be a 24/7 service: here’s when

In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.

The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.

Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.

Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.

The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.

Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.

The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
