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 launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid
You’re making £££ and the community is powered by clean energy

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.

The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.

Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.
