Tesla’s California Virtual Power Plant (VPP) has been growing quietly in the background, and its growth since the middle of 2022 has been substantial. As per data tracked by the EV community, it would appear that the California VPP has grown to over 5,700 homes from both PG&E and SoCal Edison customers. 

A virtual power plant allows multiple homes to band together as a way to support the grid when needed. In the case of the CA VPP, the system is comprised of homes that are equipped with Tesla Powerwall batteries and solar panels. During times when the grid needs support, the VPP could be tapped to provide energy. 

As per an active tracker of the California Virtual Power Plant on LastBulb, there have been ten events between August 17, 2022 and September 9, 2022 where the system was tapped to support the grid. Overall, the tracker estimates that ~577 MWh was contributed by the system during grid events in 2022, which is quite impressive for a pilot program. 

Overall, each home that took part during the grid events last year seemed to have contributed an average of ~15 kWh to the grid per event. This is quite manageable, especially if the grid events happened during times when a home’s Powerwall batteries were also storing energy from solar panels. Overall, LastBulb estimates that the system was able to provide ~84 MWh of potential backup energy per event

It would be interesting to see just how much better the California Virtual Power Plant would perform in the next grid events. During the last tracked grid event on September 9, after all, the VPP was estimated to have been comprised of just 4,600 homes. By the end of the year, the system is estimated to have grown about 20% to 5,721 homes. With a larger fleet, Tesla’s California Virtual Power Plant could truly provide a meaningful amount of energy to support the state’s grid.

Donald Trump turns to Elon Musk and Starlink amid Iran internet blackout

Donald Trump has stated that he plans to speak with SpaceX CEO Elon Musk about restoring internet access in Iran, as authorities in the country implement an internet blackout amid nationwide anti-government protests. 

Trump points to Starlink

Speaking to reporters in Washington, Trump said Musk would be well-suited to help restore connectivity in Iran, citing his experience operating large-scale satellite networks, as noted in a Reuters report. “He’s very good at that kind of thing, he’s got a very good company,” Trump said. 

Iran has experienced a near-total internet shutdown for several days, severely limiting the flow of information as protests escalated into broader demonstrations against the country’s rulers.

Starlink has previously been used in Iran during periods of unrest, allowing some users to access the global internet despite government blocks. Neither Musk nor SpaceX immediately commented on Trump’s remarks, but Musk has publicly supported efforts to provide Starlink access to Iranians during earlier periods of unrest.

Renewed Trump–Musk ties

Trump’s comments come amid a thaw in his previously strained relationship with Musk. The two had a public falling-out last year over domestic policy disagreements but have since appeared together publicly, including at Trump’s Mar-a-Lago resort. The renewed ties now intersect with foreign policy, as Starlink has become a strategic tool in regions facing censorship or conflict.

The satellite service has also played a prominent role elsewhere, most notably in Ukraine, highlighting both its potential impact and the political sensitivities surrounding its use. In Iran, Starlink support previously followed coordination between Musk and U.S. officials during protests in 2022.

The current internet blackout in Iran has drawn international attention, with rights groups estimating hundreds of deaths and thousands of arrests since demonstrations intensified late last year. Iranian authorities have not released official casualty figures, and outside verification remains limited due to restricted communications.

Tesla China’s domestic sales fell 4.8% in 2025, but it’s not doom and gloom

Despite the full-year dip, Tesla finished the year with record domestic sales in December.

Tesla posted 625,698 retail vehicle sales in China in 2025, marking a 4.8% year-on-year decline as the EV maker navigated an increasingly competitive EV market and a major production transition for its best-selling vehicle. 

Despite the full-year dip, Tesla finished the year with record domestic sales in December.

Retail sales slip amid Model Y transition

Tesla’s 2025 retail sales in China were down from 657,102 units in 2024, when the company ranked third in the country’s new energy vehicle (NEV) market with a 6.0% share. In 2025, Tesla’s share slipped to 4.9%, placing it fifth overall, as noted in a CNEV Post report.

Part of the decline seemed tied to operational disruptions early in the year. Tesla implemented a changeover to the new Tesla Model Y in the first quarter of 2025, which required temporary production pauses at Giga Shanghai. That downtime reduced vehicle availability early during the year, weighing on the company’s retail volumes in China and in areas supplied by Giga Shanghai’s exports.

China remained one of Tesla’s largest markets, accounting for 38.24% of its global deliveries of 1.64 million vehicles in 2025. However, the company also saw exports from Giga Shanghai fall to 226,034 units, down nearly 13% year-on-year. It remains to be seen how much of this could be attributed to the Model Y changeover and how much could be attributed to other factors.

Strong December 2025 finish

While the full-year picture showed some contraction, Tesla closed 2025 on a high note. According to data from the China Passenger Car Association (CPCA), Tesla China delivered a record 93,843 vehicles domestically in China in December, its highest monthly total ever. That figure was up 13.2% from a year earlier and 28.3% higher than November.

The surge was driven in part by Tesla prioritizing domestic deliveries late in the year, allowing buyers to lock in favorable purchase tax policies. In December alone, Tesla captured 7.0% of China’s NEV market and a notable 12.0% share of the country’s battery-electric segment.

On a wholesale basis, Tesla China sold 851,732 vehicles in 2025, down 7.1% year-on-year. From this number, 97,171 were from December 2025 alone. Tesla Model 3 wholesale figures reached 312,738 units, a year-over-year decrease of 13.12%. The Tesla Model Y’s wholesale figures for 2025 were 538,994 units, down 3.18% year-over-year.

Tesla Robovan’s likely first real-world use teased by Boring Company President

As per the executive, the vehicle will be used to move large crowds through Las Vegas during major events.

The Boring Company President Steve Davis has shared the most likely first real-world use for Tesla’s Robovan.

As per the executive, the vehicle will be used to move large crowds through Las Vegas during major events. 

Tesla Robovan for high-demand events

During a feature with the Las Vegas Review-Journal, Boring Company President Steve Davis stated that the Tesla Robovan will be used in Sin City once the Vegas Loop expands across the Strip and downtown and the fleet grows to about 1,200 Teslas. 

At that scale, Robovans would primarily be deployed during predictable surges, such as game days and large shows, when many riders are traveling to the same destination at the same time.

“The second you have four (passengers) and you have to start stopping, the best thing you can do is put your smallest vehicle in, which is a car. But if you know people are going to the stadium because of a game, you’ll know an hour before, two hours before, that a lot of people are going to a game or a Sphere show, if you are smart about it, that’s when you put a high occupancy vehicle in, that’s when you put the Robovan in,” Davis said.

Vegas Loop expansion

Steve Davis’s Robovan comment comes amid The Boring Company’s efforts to expand the Vegas Loop’s airport service. Phase 1 of rides to Harry Reid International Airport began last month, allowing passengers to travel from existing Loop stations such as Resorts World, Encore, Westgate, and the Las Vegas Convention Center.

Phase 2 will add a 2.2-mile dual-direction tunnel from Westgate to Paradise Road. That section is expected to open within months and will allow speeds of up to 60 mph on parts of the route, while expanding the fleet to around 160 vehicles.

Future phases are expected to extend tunnels closer to airport terminals and add multiple stations along University Center Drive. At this point, the system’s fleet is expected to grow close to 300 Teslas. The final phase, an underground airport station, was described by Davis as the system’s “holy grail.” This, however, has no definite timeframe as of yet.
