Tesla Powerwall 2 gets included in Australia’s battery subsidy plan for 40k homes
In a rather ironic twist, Tesla and its Powerwall 2 battery have been added to the list of choices for South Australia’s Home Battery Scheme, which aims to provide subsidies to 40,000 homes. The inclusion of the Powerwall 2 battery to the subsidy scheme comes amidst the ongoing progress of Tesla’s ambitious Virtual Power Plant in the region.
The update, which was recently reported by One Step Off The Grid, noted that Tesla’s 13.5kWh lithium-ion home battery systems are now eligible for the full AU$6,000 (US$4,300) subsidy offered by the SA government. As an additional means to attract buyers, Tesla has set up a temporary stall at the Rundle Mall in Adelaide, to showcase its battery storage technology. As noted by the Australian-based publication, though, customers are being informed that the installation of Powerwall 2 batteries would likely involve a lot of waiting.
Solar Quotes’ Ronald Brakels, who visited the Tesla pop-up store, was reportedly informed that there is an estimated 12-week waiting period for Powerwall 2 batteries. Brakels further added that he was quoted AU$9,300 (US$6,600) for the Powerwall 2 and the installation after the AU$6,000 (US$4,300) subsidy is applied. That’s still a substantial amount, and would likely be out of reach for some homeowners who are in need of a system that can lower their power bills.
This was among the concerns that were raised last year when South Australia’s Home Battery Scheme was announced as a possible replacement for Tesla’s Virtual Power Plant project. Not long after he was elected, South Australia premier Steven Marshall expressed his opposition to Tesla’s proposal of establishing a 250 MW/650 MWh virtual power plant comprised of 50,000 residential homes and Powerwall 2 batteries. As an alternative, Marshall proposed a subsidy program instead, which would lower the price of battery storage units for 40,000 homes.
“(Former Premier Jay Weatherill) was doing (Tesla’s Virtual Power Plant) for Housing Trust homes in South Australia… That’s not part of our plan. What we are going to do is provide a subsidy to get (those with) solar rooftops systems with some storage capacity,” Marshall said before shortly before he was sworn in last year.
Marshall’s plan had stark differences with Tesla’s plan for a Virtual Power Plant. For one, the battery subsidy would be offered to homes that are already equipped with solar panels. Apart from this, homeowners would be required to purchase their own batteries, albeit at a discounted price. Tesla’s Virtual Power Plant, on the other hand, plans to provide solar panels and Powerwall 2 batteries to 25,000 Housing Trust households and 25,000 private low-income homes for free.
Seemingly after receiving flak for his lack of support for Tesla’s Virtual Power Plant, Marshall eventually took a softer stance on the project. By the end of May 2018, Energy Minister Dan van Holst Pellekaan announced that the South Australian government would be pursuing Tesla’s Virtual Power Plant and Marshall’s Home Battery Scheme side-by-side.
Since then, Tesla’s Virtual Power Plant has completed its first phase, which involves the installation of solar panels and batteries to the first 100 houses in the system. Marshall’s Home Battery Scheme, on the other hand, was launched last October, and is expected to add up to 400 MWh of storage to the state’s grid when complete. Ultimately, the 400 MWh from Marshall’s Home Battery Scheme would be a nice addition to the 650 MWh of energy storage that would be provided by Tesla’s Virtual Power Plant once all 50,000 residential units are connected and online.

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.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale
The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
