Tesla Virtual Power Plant in Australia is proving that community-powered grids are feasible
Tesla’s Virtual Power Plant (VPP) in South Australia is proving that a network of homes with residential solar and battery storage systems can be used to effectively aid the national electricity grid. The project is still in its early stages, but based on its performance so far, Tesla’s VPP is looking to be yet another disruptive force in Australia’s energy market.
The Australian Energy Market Operator (AEMO) recently released the first report from its Virtual Power Plant Demonstration Program. The report showed how consumer devices, when aggregated and coordinated, can contribute to a secure electricity system in a real-world setting. Based on the report, the South Australia VPP has been tapped to support the region’s grid several times since its first phases were completed, and so far, the verdict has been resoundingly positive.
In October 2019, for example, the VPP was tapped to address an unexpected failure at one of the region’s biggest generating units at the Kogan Creek Power Station, which took out 748 MW of capacity. Immediately after the failure, the Tesla VPP detected the frequency excursion and responded quickly, helping in frequency recovery. The quickness of the Virtual Power Plant was impressive, and it hinted that a community-driven, sustainable backup system might very well be feasible.
Even in instances when the VPP underperformed, the system still showed potential. During the Victoria and South Australia regional separation event in November 2019, which left South Australia islanded for almost five hours, the Virtual Power Plant was only able to deliver 828 kW out of the needed 1 MW, as noted by Energy Locals and Tesla in their report. This proved to be a small speed bump for the VPP, though, as the issue was immediately fixed by remotely reconfiguring non-compliant systems in the power plant.
“Since this event, Tesla informs AEMO that it has introduced daily checks on all systems to ensure they are responding according to the expected configuration requirements. It is expected that this approach will mitigate the risk of any future under-delivery,” the report read.
Tesla’s South Australia Virtual Power Plant had another chance to prove itself in December 2019, when the National Electricity Market experienced both high and low-frequency events within 45 minutes of each other. The response from the VPP was quick, charging its batteries to lower system frequency, and then discharging the energy storage units to raise system frequency. This event, if any, showed that the community-driven system was very flexible.
Tesla has provided its own insights based on the South Australia Virtual Power Plant’s performance so far. The company noted that the system had several opportunities to demonstrate its capabilities, as well as provide hints at its revenue earning potential. “Specifically, the capability of aggregated assets to rapidly respond to frequency deviations and provide critical system security services. This has also meant VPPs can access revenues from markets that aggregated assets, particularly smaller aggregated assets, have traditionally been excluded from,” Tesla noted.
What is most remarkable is that Tesla’s Virtual Power Plant in South Australia is already addressing the needs of the grid despite being only fractionally complete. The project is reportedly in its second phase, which involves the network growing to about 1,100 homes equipped with residential solar and Powerwall batteries. This is but the tip of the iceberg for Tesla’s actual VPP plans, as the electric car maker aims to build a network of 50,000 homes that are ready to serve as backup to the region’s grid anytime. If ~1,100 homes can already perform this well, then it’s pretty exciting to infer how capable a completed, 50,000-strong Tesla Virtual Power Plant could be.

Tesla Energy celebrates one decade of sustainability
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy recently celebrated its 10th anniversary with a dedicated video showcasing several of its milestones over the past decade.
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy Early Days
When Elon Musk launched Tesla Energy in 2015, he noted that the business is a fundamental transformation of how the world works. To start, Tesla Energy offered the Powerwall, a 7 kWh/10 kWh home battery system, and the Powerpack, a grid-capable 100 kWh battery block that is designed for scalability. A few days after the products’ launch, Musk noted that Tesla had received 38,000 reservations for the Powerwall and 2,500 reservations for the Powerpack.
Tesla Energy’s beginnings would herald its quiet growth, with the company later announcing products like the Solar Roof tile, which is yet to be ramped, and the successor to the Powerwall, the 13.5 kWh Powerwall 2. In recent years, Tesla Energy also launched its Powerwall 3 home battery and the massive Megapack, a 3.9 MWh monster of a battery unit that has become the backbone for energy storage systems across the globe.
Key Milestones
As noted by Tesla Energy in its recent video, it has now established facilities that allow the company to manufacture 20,000 units of the Megapack every year, which should help grow the 23 GWh worth of Megapacks that have already been deployed globally.
The Powerwall remains a desirable home battery as well, with more than 850,000 units installed worldwide. These translate to 12 GWh of residential entry storage delivered to date. Just like the Megapack, Tesla is also ramping its production of the Powerwall, allowing the division to grow even more.
Tesla Energy’s Role
While Tesla Energy does not catch as much headlines as the company’s electric vehicle businesses, its contributions to the company’s bottom line have been growing. In the first quarter of 2025 alone, Tesla Energy deployed 10.4 GWh of energy storage products. Powerwall deployments also crossed 1 GWh in one quarter for the first time. As per Tesla in its Q1 2025 Update Letter, the gross margin for the Energy division has improved sequentially as well.
Tesla Energy shined in what was a weak delivery report for the first quarter, as the company’s frequently-forgotten battery storage products performed extraordinarily well.
Tesla reported its Q1 production, delivery, and deployment figures for the first quarter of the year, and while many were less-than-excited about the automotive side, the Energy division performed well with 10.4 GWh of energy storage products deployed during the first quarter.
This was a 156 percent increase year-over-year and the company’s second-best quarter in terms of energy deployments to date. Only Q4 2024 was better, as 11 GWh was recorded.
Tesla Energy is frequently forgotten and not talked about enough. The company has continued to deploy massive energy storage projects across the globe, and as it recorded 31.5 GWh of deployments last year, 2025 is already looking as if it will be a record-setting year if it continues at this pace.

Although Energy performed well, many investors are privy to that of the automotive division’s performance, which is where some concern lies. Tesla had a weak quarter for deliveries, missing Wall Street estimates by a considerable margin.
There are two very likely reasons as to why this happened: the first is Tesla’s switchover to the new Model Y at its production facilities across the globe. Tesla said it lost “several weeks” of production due to the updating of manufacturing lines as it rolled out a new version of its all-electric crossover.
Secondly, Tesla could be facing some pressure from pushback against the brand, which is what many analysts will say. Despite the publicity of attacks on Tesla drivers and their vehicles, as well as the company’s showrooms, it would be safe to assume that we will have a better picture painted of what the issue is in Q2 after the company reports numbers in July.
If Tesla is still struggling with lackluster delivery figures in Q2 after the Model Y is ramped and deliveries are more predictable and consistent, we could see where the argument for brand damage is legitimate. However, we are more prone to believe the Model Y, which accounts for most of Tesla’s sales, and its production ramp is likely the cause for what happened in Q1.
In what was a relatively bleak quarter, Tesla Energy still shines as the bright spot for the quarter.
Tesla has chosen the location of its latest manufacturing project, a facility that will churn out the Megapack, a large-scale energy storage system for solar energy projects. It has chosen Waller County, Texas, as the location of the new plant, according to a Commissioners Court meeting that occurred on Wednesday, March 5.
Around midday, members of the Waller County Commissioners Court approved a tax abatement agreement that will bring Tesla to its area, along with an estimated 1,500 jobs. The plant will be located at the Empire West Industrial Park in the Brookshire part of town.
Brookshire also plans to consider a tax abatement for Tesla at its meeting next Thursday.
The project will see a one million square-foot building make way for Tesla to build Megapack battery storage units, according to Covering Katy News, which first reported on the company’s intention to build a plant for its energy product.
CEO Elon Musk confirmed on the company’s Q4 2024 Earnings Call in late January that it had officially started building its third Megapack plant, but did not disclose any location:
“So, we have our second factory, which is in Shanghai, that’s starting operation, and we’re building a third factory. So, we’re trying to ramp output of the stationary battery storage as quickly as possible.”

The Megapack has been a high-demand item as more energy storage projects have started developing. Across the globe, regions are looking for ways to avert the loss of power in the event of a natural disaster or simple power outage.
This is where Megapack comes in, as it stores energy and keeps the lights on when the main grid is unable to provide electricity.
Vince Yokom of the Waller County Economic Development Partnership, commented on Tesla’s planned Megapack facility:
“I want to thank Tesla for investing in Waller County and Brookshire. This will be a state-of-the-art manufacturing facility for their Megapack product. It is a powerful battery unit that provides energy storage and support to help stabilize the grid and prevent outages.”
Tesla has had a lease on the building where it will manufacture the Megapacks since October 2021. However, it was occupied by a third-party logistics company that handled the company’s car parts.
