Tesla teases world’s largest Virtual Power Plant in South Australia
Tesla recently posted the first teaser of its virtual power plant project in South Australia, providing a brief overview of the initiative, the resources it will entail, as well as its benefits to residents in the region.
Tesla’s South Australia virtual power plant, which will be comprised of 50,000 residential homes fitted with solar panels and Powerwall 2 home batteries, will be the world’s largest VPP system when completed. The company also noted that the system was specifically designed to support the state’s energy needs by lowering power rates for residents and providing additional stability to the grid.
Tesla’s virtual power plant for South Australia was approved by the ruling Liberal party last May, after Energy Minister Dan van Holst Pellekaan reaffirmed the government’s support for the project at the Australian Energy Storage Conference.
“It’s very important to be clear about this — we are honoring the existing commitments around the Tesla virtual power plant (VPP). The VPP project is currently proceeding with the two trial phases as planned. The trial phases involve installation of home energy systems on 1,100 Housing SA homes. These are supported by a $2 million grant and a $30 million loan from the State Government. Subject to private finance, and the first two phases’ success, the third phase could grow to up to 50,000 home batteries connected to new solar installations, and this is in addition to our government’s 40,000 home election commitment,” he said.
Before the Energy Minister’s announcement in May, Tesla’s virtual power plant seemed like it was in danger of being canceled. The comprehensive energy initiative was conceived by Tesla and the Labor party, but when the Liberal Party won the elections last March, new South Australian Premier Steven Marshall noted in a statement that his government would not be supporting the project. Instead, Marshall proposed a different energy initiative — one that involves giving subsidies for 40,000 homes to purchase home battery systems.
Unlike Tesla’s virtual power plant, Marshall’s plan would require homeowners to pay for their battery packs (albeit at a lower price), which would make the system unattainable for low-income households. Marshall’s plan would also be limited to homes that were already fitted with solar panels. In comparison, Tesla’s virtual power plant would provide both solar panels and Powerwall 2 batteries to low-income households for free.
Amidst backlash over his lack of support for the South Australia virtual power plant, Marshall ultimately took a more moderate stance on the project just a few days later. By the end of May, Energy Minister Dan van Holst Pellekaan announced the government’s support. The South Australian government further noted that Tesla’s virtual power plant would be set up alongside Marshall’s alternative battery storage subsidy plan.
Tesla’s virtual power plant project in South Australia is expected to deliver 250 MW of solar energy and 650 MWh of battery storage capacity when complete, dwarfing Hornsdale Wind Farm near Jamestown, which has a 100MW/129MWh capacity. The South Australia state government is assisting with the release of a $2 million grant and a $30 million loan from the Renewable Technology Fund to get the project underway. Additional funding for the virtual power plant, which is estimated to cost a total of $800 million when complete, is expected to be addressed by private investors.
The first phase of the South Australia virtual power plant, which involves the installation of solar panels and Powerwall 2 batteries to the first 1,100 homes in the system, is already underway.

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.
