Tesla may revisit vehicle-to-grid (V2G) bi-directional charging solution
Tesla could soon revisit the idea of using its electric cars as a battery power source, likely as part of the company’s Vehicle-To-Grid (V2G) bi-directional solutions.
Musk’s update came as a response to a Twitter request from Cody Walker, a Tesla enthusiast, who inquired if the electric car maker would eventually introduce a feature where one car can provide battery power to another vehicle. Responding to the inquiry, Musk noted that previous Tesla vehicles had the capability to use its battery for outputting power.
Very early on, we had the ability to use the car as a battery outputting power. Maybe worth revisiting that.

The Vehicle-To-Grid concept involves the use of electric car batteries to provide electricity back to the grid. The V2G model uses excess capacity from an electric car’s battery capacity to provide power to the electric grid in response to peak load demands. Such a system could result in several benefits, including lower power bills for homes adopting V2G.
The idea of using electric cars as a battery power source has been suggested in the past, particularly during the time of the SolarCity acquisition. For one, Ben Hill, Tesla’s vice president for energy in Europe and Africa back in 2016, mentioned that vehicle-to-grid systems would be introduced and be functional “very, very soon.” Speaking to at the 2016 Intersolar Conference at Dubai World Trade Centre, Hill noted that V2G technology is quite promising, though it still needs some fine-tuning.
“There is a lot of pilots programs going around the world right now. The ability for battery systems, which are connected to the grid, whether there in a vehicle or not, that ability is coming very, very soon,” he said.
Even teardown specialists critical of Tesla’s vehicles like the Model 3, such as Detroit veteran Sandy Munro, for example, have lauded Tesla’s progress in its battery technology. With this in mind, and with Elon Musk’s recent mention of a $100/kW breakthrough for battery cells in the near future, the time could very well be ripe for the electric car maker to revisit V2G solutions. Tesla’s battery packs, if any, are large enough for the task, considering that an average US household consumes roughly 30 kWh of electricity per day, and Tesla’s smallest battery pack in its vehicles stores 75 kWh of energy.
Vehicle-To-Grid bi-directional charging solutions have been explored by other carmakers in the past. Back in 2013, Nissan introduced a 6 kW bi-directional “LEAF-To-Home” system in Japan, which uses the electric car’s batteries to help lower the electricity bills of homes. As a means to demonstrate the potential of the technology, Nissan introduced the “Vehicle-To-Building” concept, which involved connecting six LEAFs to a building’s power distribution board, saving on power costs during peak hours. The potential savings of Nissan’s system was only around $5,000 per year for the Vehicle-To-Building model, but it was nonetheless a demonstration of how the technology could work.
The introduction of V2G solutions for Tesla vehicles might be coming at the right time for the electric car and energy company. The necessary components for the system, after all, are pretty much in place after Tesla merged with SolarCity. The former, after all, produces battery packs, while the latter provides homes with solar solutions. The companies’ technologies already came together for the Tesla Powerwall and the Solar Roof tiles. Thus, an idea like V2G would be a logical step forward for the company.
There is a certain risk with V2G solutions, however. The technology, after all, could be abused by charging the electric cars at Superchargers (which are free) and using the stored energy for their homes. If Tesla could come up with a way to prevent this from happening, however, the company could very well have another killer system in its hands.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”
The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.
Tesla lands in Texas for latest Megapack production facility
Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
What began as an open secret in the energy industry was confirmed by the U.S. Department of the Interior on Monday: Tesla is the buyer behind LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
What began as an open secret in the energy industry is becoming more real after the U.S. Department of the Interior named Tesla as the stakeholder in the LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027. The announcement, made as part of the Indo-Pacific Energy Security Summit results, ends months of speculation.
“American-made cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain.”, notes a press release on the U.S. Department of the Interior website.
Tesla has long utilized China’s Contemporary Amperex Technology Co. (CATL), the world’s largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that’s particularly reliant on LFP cells for products including its Megapack battery storage units designed for utilities and large-scale commercial projects.
The announcement of a deepened partnership between LG Energy Solution and Tesla has strategic logic for both parties. For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On. LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site, with a production capacity of 50 GWh per year. LG Energy said the contract includes options to extend the supply period by up to seven years and boost volumes based on further consultations.
For the broader industry, the ripple effects are significant. This deal signals that domestic battery manufacturing can be financially viable and not just aspirational. Utilities, energy developers, and rival automakers will take note as American-made LFP supply becomes a competitive reality rather than a distant promise.
For consumers, the benefits will take time but are real. A more resilient, U.S.-based supply chain means fewer price shocks from trade disputes, more stable Megapack availability for the grid storage projects that reduce electricity costs, and long-term downward pressure on energy storage prices as domestic production scales.
Deliveries are set to begin in 2027 and run through mid-2030, and as grid storage demand accelerates, reliable, US-made battery supply is no longer a future ambition. It is becoming a core requirement of the country’s energy strategy.

Tesla Energy gains UK license to sell electricity to homes and businesses
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.
The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.
Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.
Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.
Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.
The new UK license arrives as Tesla continues expanding its global energy business.
Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.
The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.
At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
