Future Teslas Could Come “Energy Included”
Future Teslas could come “energy included”, no matter how much you drive, for the life of the car. Crazy as it sounds, Tesla can actually make money giving Tesla owners free energy at home not just at Superchargers. Key components are already on the road or under development at Tesla. So, how would this work, when will it happen and what does it mean for Tesla owners and Tesla investors?
How it works
Tesla can provide grid regulation and stabilization services worth as much as the energy used for charging, or more, by centrally controlling the time and rate at which Tesla cars are charged. Embedding a modest up-front cost increment into the price of a special Tesla charging connector, pays energy cost in excess of earnings from grid regulation and stabilization as an “annuity”, and can leave a lot of money in Tesla’s pocket, too. This model is similar to Tesla’s Supercharger business – there is a detailed analysis of Tesla’s Supercharger business I did a while back on Seeking Alpha.
Owners will handle charging differently. Instead of setting charging current, normal or range charging, and (optionally) the charging start time, the owner will instead set a time for charging to be completed and whether a normal or range charge is needed by that time. The Tesla charging control center will then match the charging rate of each Tesla car using over-the-air communication links to earn grid regulation fees and capture the best electric rates while making sure each car is recharged when the owner needs to drive off.
Central Control of Charging Rate Provides Grid Stabilization
Your garage charging connector will be fed from a separate meter and the connector will “identify itself” to the car to enable Tesla controlled charging.
Two things make this scheme economically viable. There is flexibility in exactly when your Tesla charges because most days the charging time is much less than the time your car spends plugged in overnight. This flexibility lets charging be “timed” to help regulate the grid. When wind generation surges due to gusts, or when system load suddenly drops, chargers can be switched on to “swallow” the power surge. The grid system operator, working through the Tesla charging control center can rapidly adjust the charging load to help stabilize the grid.
Rapid adjustment of loads on the grid is valuable because it allows the grid to use more wind power with less fossil generation online as “spinning reserve”. When a large number of car chargers quickly switch on to “swallow” a surge in wind generated power, the value of the “regulation down” can actually be greater than that of the energy used by the chargers. At these times, the system operator will actually pay to have cars charge!
When will free home charging happen?
The answer is, we aren’t there yet. Utilities are only beginning to wrestle with what happens when large amounts of battery storage get connected to the grid. This turns out to be quite complicated. This Sierra Club Energy-Storage Cost-Effectiveness paper offers a summary of the results of several grid storage studies done for the California Independent System Operator (CAISO). At this point we can’t do a specific financial model because technologies, rate structures and even how grid regulation will work with attached storage have not been set.
There are also, at this point, too few Tesla cars on the road to make their charging a significant source of grid regulation. And so far, there is no central control system in place to coordinate the charging of Tesla cars. But times are changing.
CAISO now operates a unified energy imbalance market (EIM) across all or parts of seven states (CA, ID, NV, OR, UT, WA, WY). Within a few years one can imagine upwards of half a million Teslas registered in these states. When these cars are (mostly) plugged in for charging at night, they together represent several giga-watts of load that can be switched on or off in seconds, using the central charging control scheme. That’s a lot of wind regulation capability that requires almost no additional capital investment. It just might get us “free” energy to charge Tesla cars in their owner’s garages.
Status: Where are we on the path to free energy?
Tesla is doing a lot more with grid connected storage and grid regulation than many Tesla owners, and even many Tesla investors realize. In May of this year, J.B. Straubel, Tesla’s Chief Technology Officer made the keynote presentation at Silicon Valley/ SEEDZ Energy Storage Symposium. He discussed a surprising array of Tesla storage products already being made and installed in grid applications, from small residential storage systems being rolled out by SolarCity to large industrial units delivering hundreds of kilowatts. Video of JB’s presentation is available on YouTube here.
A lot of the hardware needed for central charging control of Tesla cars is already part of every Tesla. Every Model S already has a big battery, of course. And high power 10kW or 20kW chargers that are controlled through the touchscreen and the car’s computer. Every Tesla car has a broadband communication link to Tesla company computers that is used to download software updates. These links are available to control charging on a car-by-car basis. Tesla already makes a high power wall connector (HPWC) that can be installed with connection through a standard utility meter. Buying and installing one of these will probably be a requirement to get “free” charging at home.
The only part of the remote charging scheme that isn’t online today is the central control system for “aggregating” car charging so it can be controlled by the grid system operator. Everything else needed to implement aggregated charge control for Tesla cars is either already in production at Tesla or available off the shelf as commercial products or communication services.
In his talk, JB describes aggregation of many residential storage systems to allow the grid operator to use that distributed resource in much the same way aggregated car charging control might be used to stabilize and regulate the grid. At the end of his talk, there is a Q and A session. Someone asks what Tesla’s plans are for eventually implementing the aggregated control center JB described. His answer, “We are building it now.”
Should Tesla owners / investors care about this?
Probably, but some caution is warranted. Tesla owners already talk to their ICE driving friends about how much less electricity costs compared to gasoline or diesel fuel. If in the future all Tesla charging is free, both at home and from Superchargers when traveling long distances, Tesla owners will be left with literally “nothing” to talk about – something their fossil fueled friends may (or may not) appreciate.
For Tesla investors, the prospect of making all the energy for Tesla cars free has some big implications. If the economics parallel those of the Supercharger business, Tesla could see very large additional profit (billions of dollars at least) for something that would require negligible new capital investment by Tesla.
There will be indirect benefits for Tesla, too. Already Tesla cars offer the advantage of much lower energy cost compared to ICE cars, and even hybrids. Free charging at home and at Superchargers would make Tesla cars energy cost even lower than other electric cars which get charged on the owner’s electric meter. While the absolute economic advantage of free charging, compared to other electric cars, will be modest, the emotional value of getting energy for free should never be underestimated as a competitive edge in the market place.
And of course there is the plain, simple novelty of offering a car that costs nothing to run. This is a feature no other car is likely to have, and which no other car (with the exception of soap box derby and solar-car competition cars) has had before. It is newsworthy, people will talk and write about it and it will produce a lot of buzz and free advertising for Tesla. Tesla investors need to be careful not to be overcome with hysteria as the shares go up, yet again.

Tesla Robotaxi appears to be heading to a new U.S. city
Things are expanding for Robotaxi, but the big sign that it is really moving along greatly will be with the expansion to a new city. Tesla has not gone outside of Austin or the Bay Area as of yet, and launching in a new city will be a great indicator of progress.
Tesla Robotaxi appears to be heading to a new U.S. city, and although the company has revealed plans to launch in six new metros this year, it has yet to establish a new location outside of Austin and the Bay Area of California, where it has operated since last Summer.
A lot full of Model Y vehicles was spotted in Henderson, a town just north of Las Vegas, but there seems to be more than just this hint indicating that the Sin City will be the next location to offer potentially driverless rides in a Tesla using its Full Self-Driving suite.
These Model Ys are not your typical vehicles, as they are fitted with hardware that is only on Robotaxis: a rear camera washer is the dead giveaway:
🚨 These rear camera washers are only present on Robotaxi vehicles
Maybe Las Vegas is the next city to get the Robotaxi suite 😀 https://t.co/my3da5L4zc pic.twitter.com/jYFQuX1j2E

The photos and video of the lot were taken by TheZacher on X, who spotted the Model Y fleet in the Henderson parking lot.
The rear camera washer is the main piece of evidence here that indicates Tesla could be looking to expand Robotaxi to Las Vegas, a major ride-hailing hot spot, as it is one of the biggest tourist attractions in the United States. Ride-sharing is a major industry in Vegas, especially for those who are staying off the Strip.
Tesla has also been extremely transparent that Vegas is on its radar for the Robotaxi fleet, as it revealed last year that it was one of five new U.S. cities that it planned to launch the ride-hailing service in this year.
Tesla confirms Robotaxi is heading to five new cities in the U.S.
The others were Phoenix, Dallas, Houston, and Miami.
Things are expanding for Robotaxi, but the big sign that it is really moving along greatly will be with the expansion to a new city. Tesla has not gone outside of Austin or the Bay Area as of yet, and launching in a new city will be a great indicator of progress.
It will also give Tesla a new benchmark against rival company Waymo, which has operated in Las Vegas for some time.

Tesla Roadster gets new unveiling date once again
Musk announced last year that the unveiling, which initially happened back in 2018, would take place on April Fool’s Day. Initial deliveries at the 2018 event were slotted for 2020, but delays in the project, as well as prioritization of other things, continued to push the Roadster back.
The Tesla Roadster is perhaps the most anticipated vehicle in the company’s history, but those who have been waiting anxiously for it will have to push their timelines back once again.
Tesla CEO Elon Musk has revealed that the company is once again pushing back the unveiling event that was originally planned for April 1. It will now take place “probably in late April.”
True.
New Roadster unveil probably in late April. https://t.co/NShZxpK5cI

Musk announced last year that the unveiling, which initially happened back in 2018, would take place on April Fool’s Day. Initial deliveries at the 2018 event were slotted for 2020, but delays in the project, as well as prioritization of other things, continued to push the Roadster back.
There has been so much hype about the Roadster that people are right to be excited about the prospect of its existence.
Musk’s most recent rumblings about the vehicle came last Fall, when he appeared on the Joe Rogan Experience podcast, where he once again hinted the car would be able to hover for a short period.
He said:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveiling ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Additionally, he said the vehicle would not be something that would prioritize safety. Musk said that “If safety is your number one goal, do not buy the Roadster.” It’s made for speed and excitement, not for grocery-getting.
Elon Musk just said some crazy stuff about the Tesla Roadster
As the April 1 unveiling event that was originally planned was nearing without any communication to fans, media, or anyone who would potentially be in attendance, it seemed to be pretty obvious that Tesla was not ready to pull the trigger on the event quite yet.
There could be some last-minute things to finalize, or it could be something else. One thing is for certain, though: we are not super surprised that things were moved back.
Tesla has definitely been putting some things in motion for the Roadster. A few months back, Tesla started to ramp up hiring for the Roadster, and earlier in March, it submitted a patent application for a new seat design.

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.
