Tesla CTO JB Straubel reveals 1 GWh milestone in energy storage projects
Tesla CTO and co-founder JB Straubel recently revealed that the company’s energy division had hit a milestone — since 2015, Tesla has installed a worldwide total of 1 GWh worth of energy storage. Such a figure is almost half of the total energy storage installed across the world in 2017.
“It’s at a scale now where it’s undeniably making an impact. We see it as absolutely core to our mission as a company of accelerating sustainability. Electric vehicles, where we started, are one critical piece of that puzzle. They’re an enabler for using sustainable energy and transportation, but they need to be linked to an energy generation source.
“We really want to solve this all the way, with a big-picture mindset of truly solving the problem, not just providing someone a piece of the [solution] and then they have to go and figure out how to charge their car sustainably,” Straubel said, according to a Fast Company report.
Straubel’s statements bode well for Tesla’s energy business. While competitors such as South Korea’s LG and China’s BYD are emerging in the energy storage market, the California-based company has nonetheless established a lead in the emerging industry. Tesla has started the year strong, installing 373 MWh of energy storage projects during the first quarter alone.
Straubel reiterated Tesla’s goal of increasing its energy business threefold this 2018. According to the CTO, however, even if Tesla manages to scale its energy business 300% this year, transitioning the world to sustainable energy will still take a considerable amount of time. Ultimately, Straubel called on other energy companies to get involved.
“Even at 300%, we’ll need to grow it this way for decades, frankly, to really solve the problem. And not just us, but other companies need to get involved, too,” Straubel said.
Tesla’s energy business could very well be the dark horse of the Elon Musk-led company. While discussing the South Australia Powerpack farm near Jamestown during the company’s Q1 2018 earnings call, Musk teased that he is confident that Tesla would be able to announce a “gigawatt-hour scale deal within a matter of months.” Such a project would positively affect Tesla’s earnings, considering that its energy storage initiatives have so far proven to be lucrative.
Earlier this year, it was revealed that Tesla’s 129 MWh Powerpack farm in SA earned $1 million in a few days back in January. Tesla’s 10-Q form for Q1 2018 also revealed that Tesla Energy’s revenue for the first quarter reached $410 million, a 92% increase from Q1 2017. Perhaps more importantly, however, the 10-Q form also provided the first real glimpse into how much revenue Tesla can gain from its large energy projects. Below is an excerpt from Tesla’s 10-Q form for Q1 2018.
“Energy generation and storage revenue increased by $196.1 million, or 92%, in the three months ended March 31, 2018 as compared to the three months ended March 31, 2017, predominantly due to increase in Powerpack and Powerwall deliveries as well as $72.5 million revenue related to the South Australia battery project.”
Tesla’s big battery near Jamestown is but the tip of the iceberg for the company’s energy initiatives. Currently, Tesla is in the process of rolling out the first phase of its proposed 50,000-strong virtual power plant comprised of solar panels and Powerwall 2 batteries in Australia. Elon Musk also revealed that Tesla has about 11,000 ongoing energy storage projects in Puerto Rico, where the company is helping the island nation get back on its feet after getting hit by Hurricane Maria last year. If Tesla does announce a 1-GWh scale energy storage project in 2018, Elon Musk’s prediction that the company would be profitable by Q3 or Q4 2018 becomes even more plausible.

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.
