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.
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.

Global mining and construction equipment giant Liebherr recently rolled out its first-ever battery electric crawler excavator, setting a new standard in heavy earth-moving equipment capabilities with low noise levels and zero local emissions.
The company’s official copy is characteristically low-key, with an emphasis on the facts and features instead of hype:
The new model completes the product range of Liebherr crawler excavators produced in Colmar (France). It is particularly quiet and emission-free. It generates the same output as a diesel machine in the same category and is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.
Despite the lack of excitement in the release copy, there is a lot of excitement about the R 920 G8-E’s innovative new control cab philosophy.

Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USer Interface), the system integrates intelligent control logic with advanced machine learning capabilities to give operators a highly customizable interface that can follow them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the learning curve for operators on a given job site.
Liebherr says INTUSI improves both operational efficiency and user comfort on Liebherr job sites through the integration of a number of new features. From the press release:
Haptic feedback – vibrations alert the operator to critical conditions—such as reaching dynamic device limits—enhancing situational awareness and speeding up reaction times.
Optical feedback – integrated RGB LEDs on the joystick provide real-time visual cues about device status and servo control, ensuring clear communication without distraction.
Functional safety – control elements with status LEDs allow safe operation of critical functions—without requiring two-handed input—streamlining workflow while maintaining safety standards.
Hand detection – capacitive proximity sensor detects the operator’s hand automatically, enabling seamless activation of controls only when needed.
Display navigation – a mini-joystick embedded in the handle allows for quick and efficient navigation of the display interface, reducing the need to reach for external controls.
Ergonomics – multi-stage handle height adjustment ensures optimal comfort and usability, adapting to different operator preferences and working conditions
In addition to the INTUSI-powered custom cockpit, the new Liebherr R 920 G8-E electric excavator ships with your choice of either a 188 or 282 kWh high capacity li-ion battery, which is capable of 150 kW DC fast charging. Fast enough, in other words, to power up the machine during shift changes, if needed.
Electrek’s Take
R 920 G8-E electric crawler excavator; via Liebherr.
Since then, Fortescue has used the machine to move millions of tons of dirt, and has ordered several more. And, because everything from excavators to loaders to heavy trucks are built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo power, so there’s a degree of openness baked into those systems already. Liebherr is just taking that to the next level by installing an electric drive motor in place of an internal combustion engine, and I expect this excavator will be the first of many such machines from the brand.

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
