Tesla poised to unlock vehicle-to-grid abilities with ‘bi-directional’ charging systems
It appears that Tesla is building up to the eventual release of vehicle to grid (V2G) features for its fleet. Hints of this technology could be seen in the codes within the company’s vehicles, as well as the recent findings of Cruise Staff fleet Reliability Engineer Marco Gaxiola, who happened to perform an analysis of Tesla’s electric vehicle charger for the Model 3.
For the most part, Tesla has been pretty quiet about its intentions to roll out a vehicle to grid feature for its fleet. Elon Musk mentioned that it may be worth revisiting V2G in a tweet back in July 2018, but he has been quite silent about the technology since then. That being said, Tesla hacker-enthusiast @greentheonly mentioned that some references to V2G have actually been in the company’s vehicles for over a year.
Among this is the presence of logic that would allow DC to flow out of a Tesla’s battery pack. The hacker-enthusiast summed up his observations as follows “There’s logic to allow DC to flow out the battery pack. So you can supply an external grid-tie invertor with that and let it do the rest of the magic. Making it part of the HPWC would make a lot of sense in my view,” he wrote.
Vehicle to grid features are not new in the EV sphere. The Nissan Leaf, one of the first mainstream electric cars, had this feature, though its V2G technology could be used more like a manual backup power supply. This made the Leaf’s V2G solutions rather limited. But when V2G is taken at scale, and if vehicles are in smart communication with the power grid, things become a lot more compelling.
Back in 2015, Tesla CTO JB Straubel noted that once there are a million Teslas on the road, the fleet could actually have significant controllable load capacity. This milestone was reached recently by Tesla, with the company producing its millionth vehicle, a red Model Y Performance, earlier this year. And considering that Tesla is now taking on the mainstream market with the Model Y and Model 3, there is a good chance that the growth of its fleet would only accelerate over time. If Tesla were to roll out V2G features for its cars, now, or the near future, would be a preferable time to do it.
But this is not all. In a recent statement to Electrek, Cruise Staff fleet Reliability Engineer Marco Gaxiola noted that the Model 3’s charger has the necessary technology to enable bidirectional charging features. Gaxiola came to his conclusions after doing a deep dive on the Model 3 charger. “What I learned on reverse engineering the Model 3 charger, was that the design is fully bidirectional. This means power can be converted from AC to DC the same way as the previous example, but also power can flow in reverse direction, coming from the battery and ending up on the AC side,” he told the publication.
In a following LinkedIn post, the Cruise engineer noted that Tesla would likely be able to roll out its V2G features to its fleet through a software update. This could open up a lot of opportunities for electric car owners, as they could actually sell some of their vehicles’ power back to the grid.
“I believe this will be a big game changer for all the car companies looking to get into the EV market. But will also be an interesting new road to get into the utility market. Imagine that you own this vehicle, and one morning you receive an update notification that will enable this feature, which will convert your vehicle into an energy storage V2G/V2V smart system with wheels.
“You will technically be able to take energy from any AC outlet at a good rate (via your traditional L1 or L2 wall charger) and later then drive somewhere else, plug back again into another L1/L2 charger, but instead of charging you could potentially sell some of your Tesla juice back at a higher rate. This, without the need of any electrical modifications on your Tesla/Non-Tesla wall charger,” Gaxiola wrote.

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.
