Electric vehicles are part of a sustainable energy/transportation ecosystem that also includes charging infrastructure, smart grid technology and renewable energy. The key that ties all of these components together is energy storage. Storage, specifically batteries, is the enabling technology that makes modern EVs possible, and that makes renewable energy viable. Battery storage also provides a number of other benefits for the electrical grid, such as load balancing and frequency regulation.
Unsurprisingly, Tesla understood this synergy early in the game, and its Tesla Energy division has carved out a lucrative side business selling stationary battery storage to electric utilities, as well as residential and commercial energy customers (actually, “side business” may not be quite the right description, as Elon Musk has predicted that Tesla’s energy business may someday be bigger than its car business).
As a recent article in SingularityHub explains, other auto manufacturers see the possibilities and are also beginning to enter into the stationary storage market. BMW recently signed a contract to incorporate 500 i3 battery packs into the UK’s national electrical grid. Renault is developing a home energy storage product based on its Zoe batteries. Toyota and Nissan have both announced plans to offer energy storage, and Audi is one of several brands that are exploring the possibilities with pilot projects.

It’s a natural move for the automakers, who are steadily securing supplies of batteries for the EVs they’ll soon be building in volume. Volkswagen recently announced plans to invest $48 billion on battery tech over the next few years. If companies are going to be making large amounts of batteries, it simply makes sense to explore other markets that require storage.
Of course, Tesla has been doing just that for a few years now. The California trendsetter has scored some highly-publicized successes with utility-scale projects in Australia, and its Powerpacks are becoming popular for off-grid applications around the world.
But there’s more to this than just opening new markets for batteries. Tesla’s vehicles are seen as part of an ecosystem of products designed to function smoothly together. As Elon Musk explained to Fast Company, “This is the integrated future. You’ve got an electric car, a Powerwall, and a Solar Roof.” As Apple and Amazon have demonstrated, this can be an unbeatable strategy – if a customer is driving a Model S, and is impressed with the company, she’ll be that much more likely to buy a solar electric system (and why not a flamethrower, too?) from Tesla as well. The legacy automakers would be foolish to ignore the possibilities.
In dollar terms, those possibilities are staggering. Markets Insider predicts that the market for grid-connected battery storage will grow from $3.3 billion in 2016 to $14 billion by 2021, and probably well over $100 billion by 2030 – a compound annual growth rate of around 34 percent.
It’s not even necessary to produce batteries specifically for the stationary storage market. As EV batteries age, they gradually lose capacity, and drivers, who crave maximum range, will want to replace them. However, once a superannuated battery is no longer suitable for use in a vehicle, it can still be quite useful in a stationary storage application. Several automakers are investigating the possibilities of “second-life” EV batteries.

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:
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.
