Tesla’s Virtual Power Plant brings Powerwall batteries to 3K new homes in Australia
Tesla’s ambitious Virtual Power Plant project in South Australia has entered its third phase, with the initiative now aiming to add another 3,000 public housing properties to the growing solar and home battery network. With the addition of 3,000 home solar and Powerwall-equipped properties to the system, Tesla’s VPP could start providing grid support services that are equivalent to a fairly-sized battery storage system.
Phase 3 would allow the total number of homes involved in the project to grow to about 4,100 Housing SA properties across the state. Granted, this is still a small step towards Tesla’s goal of creating a Virtual Power Plant comprised of a whopping 50,000 homes, but Phase 3 could bring together roughly 20MW of rooftop solar energy and 54MWh of combined battery storage.
Functioning as a single “power plant,” the 4,100 houses in the Virtual Power Plant could play the role of a battery installation that’s only 11MWh less than the recent 50% expansion of the Hornsdale Power Reserve. In a statement to One Step Off The Grid, Energy minister Dan van Holst Pellekaan noted that the expansion of the Tesla VPP would address some of the power instability in the area.
“In a world-first, home batteries will provide the grid stability services that South Australia has lacked since the closure of the Northern Power Station, to address the legacy of instability that we inherited. This will deliver at a household level what we are also delivering through the 50% expansion of the big battery at Hornsdale Battery to address these legacy issues,” he said.
The ramp of Tesla’s Virtual Power Plant actually comes at a valuable time for South Australia, as the state is currently on track to become the first gigawatt-scale grid in the world. While this is a big milestone in the state’s push for sustainability, the growing amount of rooftop solar has become a major cause of concern for the Australian Energy Market Operator. The rollout of the Powerwall-equipped homes in the VPP could then play a role in managing the state’s huge solar resource.
“Having rooftop PV and household batteries linked through a Virtual Power Plant creates the equivalent of a grid-scale battery in our suburbs and towns, which will complement the four other grid-scale batteries already operating in South Australia. Tesla’s vision is to grow this VPP to include 50,000 homes across South Australia and has already started adding private households in addition to the Housing SA tenants participating in the project,” the minister said.
Tesla’s South Australia Virtual Power Plant has the potential to become one of the largest battery systems in the market. Once complete, the 50,000-strong system is expected to deliver 250MW of solar energy and store 650MWh of backup energy for the region. That’s far larger than the Hornsdale Power Reserve, which is already disrupting the energy landscape in South Australia even before its 50% upgrade.

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.

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:

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.
