Tesla’s giant ‘Virtual Power Plant’ made of 50k homes and Powerwalls enters 2nd phase
Tesla’s ambitious plan to establish a 250 MW/650 MWh “Virtual Power Plant” in South Australia is moving to its second phase. In an announcement last week, Minister for Energy and Mining Dan van Holst Pellekaan stated that initiatives are now underway to install Powerwall 2 home battery units and solar panels to another 1,000 Housing SA properties.
The proposed Virtual Power Plant was conceived by Tesla and South Australia’s former Labor government earlier this year. The project is undoubtedly ambitious, involving 50,000 connected homes, each fitted with a 13.5 kWh Tesla Powerwall 2 battery and a 5 kW rooftop solar system. The 50,000 houses are expected to deliver 250 MW of solar energy and 650 MWh of battery storage capacity. Just like Tesla’s Powerpack farm in South Australia, the VPP will be capable of providing additional grid stability by shifting demand away from a stressed grid during peak hours.
The first phase of the project, which involved the installation of batteries and solar panels to the first 100 houses of the VPP, has been successful so far. Households that are part of the existing system have reported a 70% reduction in their grid consumption, leading to lower power bills. With the first trial phase done, Tesla and solar retail partner Energy Locals are now looking to add 1,000 more households to the system.
Tesla’s planned Virtual Power Plant passed through several challenges this year, particularly after the Labor Party was replaced by the Liberal Party after the elections last March. In an announcement after being elected, new South Australian Premier Steven Marshall suggested that his government would not be supporting Tesla’s VPP. Marshall’s government instead proposed an alternative, involving subsidies for 40,000 homes to purchase battery systems.
Unlike Tesla’s proposed Virtual Power Plant, Marshall’s plan would require homeowners to purchase battery packs (albeit at a lower price), making the system out of reach for low-income households. Marshall’s plan is also limited to houses that are already fitted with solar panels. Tesla’s VPP, on the other hand, aims to provide both solar systems and Powerwall 2 batteries to 50,000 low-income households for free.
Marshall eventually took a more moderate stance on Tesla’s Virtual Power Plant amidst backlash over his lack of support for the project. By the end of May, Energy Minister Dan van Holst Pellekaan announced that the South Australian government would be supporting both Tesla’s proposal and Marshall’s alternative battery subsidy plan. In an announcement last week at the SA Department of Energy and Mining’s official website, van Holst Pellekaan expressed his optimism about the growing VPP.
“The VPP will deliver cheaper electricity to some of South Australia’s most disadvantaged households while increasing the reliability of the state’s electricity network. We have made South Australia the world capital of home batteries with our Home Battery Scheme attracting three battery manufacturers to South Australia and by driving forward with the VPP,” he said.
If the second phase of the Virtual Power Plant proves successful, the third, most ambitious phase of the project will commence. Provided that funding for the estimated AU$800 million ($628 million) project is secured, the system would grow to 50,000 homes over the next few years. When complete, the 50,000-strong Virtual Power Plant is expected to deliver 250 MW of solar energy and 650 MWh of battery storage capacity, dwarfing the highly successful Hornsdale Power Reserve near Jamestown, which has a 100MW/129MWh capacity.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.
Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla Shanghai Megafactory produces 1,000th Megapack for export to Europe
The Shanghai Megafactory was able to hit this milestone less than six months after it started producing the Megapack.
Tesla Energy has announced a fresh milestone for its newest Megapack factory. As per the electric vehicle maker, the Shanghai Megafactory has successfully produced its 1,000th Megapack battery.
The facility was able to hit this milestone less than six months after it started producing the grid-scale battery system.
New Tesla Megapack Milestone
As per Tesla Asia in a post on its official accounts on social media platform X, the 1,000th Megapack unit that was produced at the Shanghai Megafactory would be exported to Europe. As noted in a CNEV Post report, Tesla’s energy products are currently deployed in over 65 countries and regions globally. This allows Tesla Energy to compete in energy markets that are both emerging and mature.
To commemorate the 1,000th Megapack produced at the Shanghai Megafactory, the Tesla China team posted with the grid-scale battery with celebratory balloons that spelled “Megapack 1000.” The milestone was celebrated by Tesla enthusiasts on social media, especially since the Shanghai Megafactory only started its operations earlier this year.
Quick Megafactory Ramp
The Shanghai Megafactory, similar to Tesla’s other key facilities in China, was constructed quickly. The facility started its construction on May 23, 2024, and it was hailed as Tesla’s first entry storage project outside the United States. Less than a year later, on February 11, 2025, the Shanghai Megafactory officially started producing Megapack batteries. And by March 21, 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.
While the Shanghai Megafactory is still not at the same level of output as Tesla’s Lathrop Megafactory, which produces about 10,000 Megapacks per year, its ramp seems to be quite steady and quick. It would then not be surprising if Tesla China announces the Shanghai Megafactory’s 2,000th Megapack milestone in the coming months.
