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.

Google just picked SpaceX for its first step into orbital AI
Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.
Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.
The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.
The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.
MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.
SpaceX and Google mull massive partnership on Musk’s orbital data dream: report
Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.
The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.
Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”
Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.
