The popularity of South Australia’s Tesla-powered Virtual Power Plant (VPP) initiative which began last year is now over-subscribed, according to the state’s government officials. In response, plans are underway for the next phase of the project that will expand the VPP into a 250MW/650MWh system connecting 50,000 households.

“Results from Phase 1 and Phase 2 are already contributing towards the design of the potential Phase 3 to enable as many families as possible to benefit from this program,” Energy Minister Dan van Holst Pellekaan said in a media release on the subject.

Supported by a $2 million grant and a $20 million loan from the South Australian (SA) Renewable Technology Fund, Phases I and II of SA’s VPP involved the installation of 5 kW solar panels and a 13.5 kWh Tesla Powerwall 2 battery storage unit in 1,100 low-income households. The homes are linked together to form a virtual grid which can both ease power demands from the main grid during peak consumption times and act as a backup power source during blackouts. The final installations in this set are scheduled to be operational by October 2019, according to the SA government’s official page on the project.

Phase III of the VPP project will require additional funding and all three phases are estimated to cost a total of $800 million when complete. Private investment is expected to fill this need, which is likely to be a significant part of the SA government’s planning efforts. The current set of customers using the Phase I and II installations are offered an energy rate that’s 20% less than the main grid rates, thus making the program very popular with attractive investment potential.

Tesla is also participating in another South Australia battery program called the Home Battery Scheme. Under this initiative, AU$6,000 (US$4,300) subsidies are being offered to 40,000 homes in the state towards the purchase of lithium-ion battery systems, including Tesla’s Powerwall 2. Unfortunately, the Powerwall price may still be out of reach for many of SA’s homeowners even with the discount. In January, Ronald Brakels of Solar Quotes was given a AU$9,300 (US$6,600) post-subsidy estimate for the Powerwall 2 with installation, which is likely to be unaffordable for customers who would most benefit from a system intended to lower power bills. The Virtual Power Plant plan provides the batteries and solar panels to participants for free.

Tesla’s Powerpack 2 is also helping support other power grids in South Australia. The company’s 100 MW/129 MWh Powerpack farm at the Neoen’s Hornsdale Wind Farm near Jamestown provides a battery storage solution equivalent to about 1,300 Model S or Model X 100D consumer vehicles. Since it went online in 2017, the Hornsdale system has helped solve power shortages and manage summertime peak load to improve the reliability of South Australia’s storm-damaged electrical infrastructure. The 640 Powerpack units charge using renewable energy from the Hornsdale Wind Farm and then deliver electricity as needed.

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.

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 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.

Tesla Energy shines with substantial YoY growth in deployments

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.
