Tesla Virtual Power Plant in Australia is proving that community-powered grids are feasible
Tesla’s Virtual Power Plant (VPP) in South Australia is proving that a network of homes with residential solar and battery storage systems can be used to effectively aid the national electricity grid. The project is still in its early stages, but based on its performance so far, Tesla’s VPP is looking to be yet another disruptive force in Australia’s energy market.
The Australian Energy Market Operator (AEMO) recently released the first report from its Virtual Power Plant Demonstration Program. The report showed how consumer devices, when aggregated and coordinated, can contribute to a secure electricity system in a real-world setting. Based on the report, the South Australia VPP has been tapped to support the region’s grid several times since its first phases were completed, and so far, the verdict has been resoundingly positive.
In October 2019, for example, the VPP was tapped to address an unexpected failure at one of the region’s biggest generating units at the Kogan Creek Power Station, which took out 748 MW of capacity. Immediately after the failure, the Tesla VPP detected the frequency excursion and responded quickly, helping in frequency recovery. The quickness of the Virtual Power Plant was impressive, and it hinted that a community-driven, sustainable backup system might very well be feasible.
Even in instances when the VPP underperformed, the system still showed potential. During the Victoria and South Australia regional separation event in November 2019, which left South Australia islanded for almost five hours, the Virtual Power Plant was only able to deliver 828 kW out of the needed 1 MW, as noted by Energy Locals and Tesla in their report. This proved to be a small speed bump for the VPP, though, as the issue was immediately fixed by remotely reconfiguring non-compliant systems in the power plant.
“Since this event, Tesla informs AEMO that it has introduced daily checks on all systems to ensure they are responding according to the expected configuration requirements. It is expected that this approach will mitigate the risk of any future under-delivery,” the report read.
Tesla’s South Australia Virtual Power Plant had another chance to prove itself in December 2019, when the National Electricity Market experienced both high and low-frequency events within 45 minutes of each other. The response from the VPP was quick, charging its batteries to lower system frequency, and then discharging the energy storage units to raise system frequency. This event, if any, showed that the community-driven system was very flexible.
Tesla has provided its own insights based on the South Australia Virtual Power Plant’s performance so far. The company noted that the system had several opportunities to demonstrate its capabilities, as well as provide hints at its revenue earning potential. “Specifically, the capability of aggregated assets to rapidly respond to frequency deviations and provide critical system security services. This has also meant VPPs can access revenues from markets that aggregated assets, particularly smaller aggregated assets, have traditionally been excluded from,” Tesla noted.
What is most remarkable is that Tesla’s Virtual Power Plant in South Australia is already addressing the needs of the grid despite being only fractionally complete. The project is reportedly in its second phase, which involves the network growing to about 1,100 homes equipped with residential solar and Powerwall batteries. This is but the tip of the iceberg for Tesla’s actual VPP plans, as the electric car maker aims to build a network of 50,000 homes that are ready to serve as backup to the region’s grid anytime. If ~1,100 homes can already perform this well, then it’s pretty exciting to infer how capable a completed, 50,000-strong Tesla Virtual Power Plant could be.

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.
