Tesla’s expansion of product offerings shows that a major expansion is in the making
Over the recent weeks, Tesla appears to be setting the stage for an intensive expansion of its product offerings. From the United States to China, the company seems to be intent on pursuing more and more avenues for its electric car and energy business. This hints at one thing: a major expansion is underway, and the all-too challenging battery supply code has been cracked.
Tesla CEO Elon Musk is known for his grand and ambitious dreams. If it were up to Musk, the world would completely abandon fossil fuels and dedicate a part of its resources to exploring interplanetary solutions. But Tesla, one of Musk’s two main businesses, is heavily reliant on batteries. No matter how much Tesla or Musk would want to accelerate the ramp towards sustainability, the proverbial battery supply problem has to be solved first.
This was highlighted by Musk in a previous earnings call last year. When asked about the Tesla Semi, a Class 8 truck that was initially set to begin deliveries in 2019 but was subsequently delayed, Musk explained that the vehicle could not be ramped fully unless the issue of battery cell supply is addressed. After all, the Semi is a massive vehicle, and it uses a lot of cells.
This sentiment is pretty much universal across Tesla’s lineup, including its Energy business and in products like the humble Powerwall and the grid-scale Megapack. Longtime followers of Tesla would remember that during the height of the Model 3’s production hell, Tesla ended up using lines that were allotted for the Powerwall’s cells to produce batteries for the electric sedan instead. This resulted in delays for the home battery storage unit.
But things today are much different than before. Amidst the impending announcements for Battery Day, reports are abounding that the company is poised to reveal the latest innovations in its battery tech. Among these is a million-mile battery, which would be resilient enough to outlast the internal combustion engine when used in electric cars and durable enough to last decades if deployed as battery storage.
These breakthroughs could change everything for Tesla, and it would allow the company to expand at a rate that exceeds its already rapid growth over the years. Tesla has been providing hints about the stages of this growth, from the rollout of China-made Model 3s that are equipped with batteries that have no cobalt content, the highly-anticipated production ramp of the Semi, the aggressive timeframe for the Cybertruck, renewed battery cell deals with Panasonic, to its recent permit to become a utility provider in the United Kingdom.
Each of these projects would not be possible unless the company has cracked the code on battery cell technology and production. Today, all signs are pointing to this very scenario. This should ultimately be validating for the company and its executives, considering that it has attracted a notable amount of criticism and mockery over the years due to its intense focus and pursuit of next-generation battery tech.
Back in 2014, after all, even the MIT Technology Review noted that there is little sense in an endeavor like Gigafactory Nevada, since Tesla’s car sales then did not warrant such a demand for batteries. Critics then also argued that it would be better for Tesla to just work with existing battery manufacturers. Interestingly, ARK Invest, one of Tesla’s most ardent bulls, was one of the few that actually believed in the value of Gigafactory Nevada in 2014, stating that it while ambitious, the company’s plans for the facility are actually feasible.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
