Tesla rolls out Virtual Power Plant to SDG&E customers in San Diego
Tesla’s Virtual Power Plant program, a way for Powerwall owners to make money selling energy to the grid in times of need, is rolling out to San Diego Gas & Electric utility customers now.
SDG&E announced late last month the start of its own virtual power plant (VPP) program which would leverage household backup batteries and smart devices to reduce demand and increase supply of electricity to the grid during “demand response” events – when the grid is stressed and needs to spin up extra capacity to keep the lights on.
However, Tesla’s program is separate from SDG&E’s, even though it’s part of the same service area.
Demand response events are often expensive, because the price of a blackout is high, and the price of marginal electricity generation (often via gas peaker plants) is costly both economically and environmentally. During last year’s record heat wave, the wholesale spot price of electricity got as high as ~$2,000/MWh in parts of the state (as of the writing of this article, the price is currently ~$49/MWh).
A home or business with access to energy storage might want to leverage that storage by buying electricity while it’s cheap, and then discharging it to the grid while it’s very expensive. While this is possible on a home-to-home basis by arbitraging cheap off-peak energy and using it during on-peak times, it isn’t really great for widespread grid events unless several home storage systems can be joined together.
What does a Virtual Power Plant do?
Enter the VPP, which combines thousands of internet connected devices across a wide area and manages them all together in order to make a significant difference on the grid in times of need.
SDG&E has been running its own pilot VPP program since December, which has been tested 17 times. Participants get a message that a demand response event is coming and can choose to opt-out for certain devices (for example, to keep their air conditioning running at full blast). SDG&E says that the opt-out rate has been very low so far, suggesting that participants are happy to do their part when the grid is in need.
We saw similar behavior statewide in California last year when the grid faced its highest level of demand ever recorded on an exceptionally hot day. California’s grid operator sent out a text message to everyone in the state asking them to conserve energy, and Californians reduced their energy use by multiple gigawatts in mere minutes, thus saving the grid from overloading statewide.
But with a virtual power plant, participation doesn’t need to be voluntary, it can be automatic (for those who have signed up). And in exchange for the valuable benefit of helping to avoid blackouts by adding electricity to the grid when it is most expensive, VPP participants can be paid for their service.
We’ve already seen this happening with one of the largest and earliest VPPs out there, Tesla’s VPP in Northern California, in the service area of Pacific Gas & Electric. We saw participants receive checks of up to $575 for their first year of participation in the program.
Growth of Tesla VPP as it expands to San Diego
Tesla’s VPP program has been growing. Last time we checked in last year, it was capable of providing 50 MW across California, which is about as much as one average gas peaker plant (the state has about 7GW of gas peaker capacity total). This was right after Tesla opened up the program to SoCal Edison customers.
As of now, the site we were using to track growth has changed its measurements a little, but it looks like the system can provide ~116MWh of potential backup energy – so as much as running two gas peaker plants for an hour or so.
And as of now, Tesla Powerwall owners in San Diego can join the Virtual Power Plant program by enrolling through the same Tesla app which they use to manage their Powerwall.
All owners need to do is open up their app to the Powerwall page and tap on the “Virtual Power Plant” item, which should be at the top of the list, as seen below:
Tesla will provide an estimate of how much you can earn by participating in the program, based on the size of your system and your standard usage. Of course this is just an estimate, and you can always change your settings or usage to try to maximize this number, especially on days where demand response events are likely (e.g., hot days in California, which tend to stress the grid the most due to overuse of air conditioning).
In addition to California’s struggles with hot weather events (which are worsening due to climate change), SDG&E has rather wide time-of-use rates, with super off-peak rates of 24 cents per kWh, raising as high as 70-80 cents during on-peak times. This makes Powerwalls more attractive due to the possibility of energy arbitrage – and even more attractive during demand response events, where effective wholesale rates can go much higher than that.
Tesla also is also working on rolling out VPPs to Texas and Puerto Rico, and has another massive VPP in South Australia, an area which has been struggling with electricity issues for years now.

Hyundai is getting ready to shake things up. A new electric crossover SUV, likely the Hyundai IONIQ 2, is set to debut in the coming months. It will sit below the Kona Electric as Hyundai expands its entry-level EV lineup.
Is Hyundai launching the IONIQ 2 in 2026?
After launching the Inster late last year, Hyundai is already preparing to introduce a new entry-level EV in Europe.
Xavier Martinet, President and CEO of Hyundai Europe, confirmed that the new EV will be revealed “in the next few months.” It will be built in Europe and scheduled to go on sale in mid-2026.
Hyundai’s new electric crossover is expected to be a twin to the Kia EV2, which will likely arrive just ahead of it next year.
It will be underpinned by the same E-GMP platform, which powers all IONIQ and Kia EV models (EV3, EV4, EV5, EV6, and EV9).
Like the Kia EV3, it will likely be available with either a 58.3 kWh or 81.4 kWh battery pack option. The former provides a WLTP range of 267 miles while the latter is rated with up to 372 miles. All trims are powered by a single electric motor at the front, producing 201 hp and 209 lb-ft of torque.
Although it may share the same underpinnings as the EV2, Hyundai’s new entry-level EV will feature an advanced new software and infotainment system.
According to Autocar, the interior will represent a “step change” in terms of usability and features. The new system enables new functions, such as ambient lighting and sounds that adjust depending on the drive mode.
It’s expected to showcase Hyundai’s powerful new Pleos software and infotainment system. As an end-to-end software platform, Pleos connects everything from the infotainment system (Pleos Connect) to the Vehicle Operating System (OS) and the cloud.
Pleos is set to power Hyundai’s upcoming software-defined vehicles (SDVs) with new features like autonomous driving and real-time data analysis.
As an Android-based system, Pleos Connect features a “smartphone-like UI” with new functions including multi-window viewing and an AI voice assistant.
The new electric crossover is expected to start at around €30,000 ($35,400), or slightly less than the Kia EV3, priced from €35,990 ($42,500). It will sit between the Inster and Kona Electric in Hyundai’s lineup.
Hyundai said that it would launch the first EV with its next-gen infotainment system in Q2 2026. Will it be the IONIQ 2? Hyundai is expected to unveil the new entry-level EV at IAA Mobility in September. Stay tuned for more info. We’ll keep you updated with the latest.

Tesla has unveiled its lithium-iron-phosphate (LFP) battery cell factory in Nevada and claims that it is nearly ready to start production.
Like several other automakers using LFP cells, Tesla relies heavily on Chinese manufacturers for its battery cell supply.
Tesla’s cheapest electric vehicles all utilize LFP cells, and its entire range of energy storage products, Megapacks and Powerwalls, also employ the more affordable LFP cell chemistry from Chinese manufacturers.
This reliance on Chinese manufacturers is less than ideal and particularly complicated for US automakers and battery pack manufacturers like Tesla, amid an ongoing trade war between the US and virtually the entire world, including China.
As of last year, a 25% tariff already applied to battery cells from China, but this increased to more than 80% under Trump before he paused some tariffs on China. It remains unclear where they will end up by the time negotiations are complete and the trade war is resolved, but many expect it to be higher.
Prior to Trump taking power, Tesla had already planned to build a small LFP battery factory in the US to avoid the 25% tariffs.
The automaker had secured older manufacturing equipment from one of its battery cell suppliers, CATL, and planned to deploy it in the US for small-scale production.
Tesla has now released new images of the factory in Nevada and claimed that it is “nearing completion”:
Here are a few images from inside the factory (via Tesla):
Previous reporting stated that Tesla aims to produce about 10 GWh of LFP battery cells per year at the new factory.
The cells are expected to be used in Tesla’s Megapack, produced in the US. Tesla currently has a capacity to produce 40 GWh of Megapacks annually at its factory in California. The company is also working on a new Megapack factory in Texas.
Ford is also developing its own LFP battery cell factory in Michigan, but this facility is significantly larger, with a planned production capacity of 35 GWh.
Electrek’s Take
It’s nice to see this in the US. LFP was a US/Canada invention, with Arumugam Manthiram and John B. Goodenough doing much of the early work, and researchers in Quebec making several contributions to help with commercialization.
But China saw the potential early and invested heavily in volume manufacturing of LFP cells and it now dominates the market.
Tesla is now producing most of its vehicles with LFP cells and all its stationary energy storage products.
It makes sense to invest in your own production. However, Tesla is unlikely to catch up to BYD and CATL, which dominate LFP cell production.
The move will help Tesla avoid tariffs on a small percentage of its Megapacks produced in the US. Ford’s effort is more ambitious.
It’s worth noting that both Ford’s and Tesla’s LFP plants were planned before Trump’s tariffs, which have had limited success in bringing manufacturing back to the US.
