Tesla’s giant ‘Virtual Power Plant’ made of 50k homes and Powerwalls enters 2nd phase
Tesla’s ambitious plan to establish a 250 MW/650 MWh “Virtual Power Plant” in South Australia is moving to its second phase. In an announcement last week, Minister for Energy and Mining Dan van Holst Pellekaan stated that initiatives are now underway to install Powerwall 2 home battery units and solar panels to another 1,000 Housing SA properties.
The proposed Virtual Power Plant was conceived by Tesla and South Australia’s former Labor government earlier this year. The project is undoubtedly ambitious, involving 50,000 connected homes, each fitted with a 13.5 kWh Tesla Powerwall 2 battery and a 5 kW rooftop solar system. The 50,000 houses are expected to deliver 250 MW of solar energy and 650 MWh of battery storage capacity. Just like Tesla’s Powerpack farm in South Australia, the VPP will be capable of providing additional grid stability by shifting demand away from a stressed grid during peak hours.
The first phase of the project, which involved the installation of batteries and solar panels to the first 100 houses of the VPP, has been successful so far. Households that are part of the existing system have reported a 70% reduction in their grid consumption, leading to lower power bills. With the first trial phase done, Tesla and solar retail partner Energy Locals are now looking to add 1,000 more households to the system.
Tesla’s planned Virtual Power Plant passed through several challenges this year, particularly after the Labor Party was replaced by the Liberal Party after the elections last March. In an announcement after being elected, new South Australian Premier Steven Marshall suggested that his government would not be supporting Tesla’s VPP. Marshall’s government instead proposed an alternative, involving subsidies for 40,000 homes to purchase battery systems.
Unlike Tesla’s proposed Virtual Power Plant, Marshall’s plan would require homeowners to purchase battery packs (albeit at a lower price), making the system out of reach for low-income households. Marshall’s plan is also limited to houses that are already fitted with solar panels. Tesla’s VPP, on the other hand, aims to provide both solar systems and Powerwall 2 batteries to 50,000 low-income households for free.
Marshall eventually took a more moderate stance on Tesla’s Virtual Power Plant amidst backlash over his lack of support for the project. By the end of May, Energy Minister Dan van Holst Pellekaan announced that the South Australian government would be supporting both Tesla’s proposal and Marshall’s alternative battery subsidy plan. In an announcement last week at the SA Department of Energy and Mining’s official website, van Holst Pellekaan expressed his optimism about the growing VPP.
“The VPP will deliver cheaper electricity to some of South Australia’s most disadvantaged households while increasing the reliability of the state’s electricity network. We have made South Australia the world capital of home batteries with our Home Battery Scheme attracting three battery manufacturers to South Australia and by driving forward with the VPP,” he said.
If the second phase of the Virtual Power Plant proves successful, the third, most ambitious phase of the project will commence. Provided that funding for the estimated AU$800 million ($628 million) project is secured, the system would grow to 50,000 homes over the next few years. When complete, the 50,000-strong Virtual Power Plant is expected to deliver 250 MW of solar energy and 650 MWh of battery storage capacity, dwarfing the highly successful Hornsdale Power Reserve near Jamestown, which has a 100MW/129MWh capacity.

Tesla meets Giga New York’s Buffalo job target amid political pressures
Giga New York reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease.
Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year.
The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.
As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.
The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.
Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.
Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.
Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation.
“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.

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…
— Wes (@wmorrill3) December 12, 2025
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.
