Tesla partners up to expand Virtual Power Plant program in Texas
More Tesla Powerwall customers are coming to the distributed battery program in South-Central Texas.
Tesla is a part of a new energy partnership in Texas set to help expand the company’s Virtual Power Plant (VPP) program in the state, as announced by one energy provider this week.
In a press release on Monday, the Guadalupe Valley Electric Cooperative (GVEC) announced a partnership with Tesla and the Electric Reliability Council of Texas (ERCOT) to participate in a utility-scale VPP pilot program. Dubbed the Aggregated Distributed Energy Resource (ADER), the pilot will utilize Tesla’s Powerwall home battery systems to create a distributed “battery” across owners, in order to help stabilize the grid and provide backup power in times of peak demand.
GVEC says the early ADER program has already registered around 17 MW of generation from Tesla’s Powerwall customers, and the utility provider’s Board President Gary Birdwell highlights how important the subject of energy storage is in today’s climate.
Tesla Energy’s Powerwall home battery is super underrated, and it has so much potential in areas that are typically affected by power outages.

“Consumer generated energy is quickly becoming an important resource for the Texas wholesale electricity market,” Birdwell said in a statement. “Cooperation between GVEC and Tesla, two prominent market participants, uniting to utilize their strengths for the common goal of building stability and resiliency of the grid is a strategic move.”
Through Tesla’s VPP programs, such as this one, Powerwall owners can essentially sell generated and stored electricity back to the grid when demand is high or the grid is facing outages. GVEC does this through what it calls the Peak-Time Payback (PTP) program, offering mutual support for customers and ERCOT grid operators.
The group describes itself as a cooperative group providing electricity and electrician services, solar and energy storage, internet, air conditioning and heating to over 130,000 customers in South-Central Texas across Cuero, Gonzales, La Vernia, Schertz and Seguin. GVEC says it officially became a certified Tesla battery installer in the region in 2019, adding that Powerwall installations have continued to increase in the years since.
“Tesla has been a major player in the ADER pilot program since its inception. They are a highly visible company with the capabilities and expertise to meet the robust participation requirements,” says Darren Schauer, GVEC General Manager and CEO. “As an additional benefit, GVEC has the ability to offer ancillary services directly onto the market. This means GVEC Powerwall members can now support the needs of the Texas grid while also creating a new revenue stream to reinforce the long-term financial strength of their member-owned cooperative.”

As of Q3 2024, Tesla said it had over 100,000 Powerwalls participating in its VPP programs globally, and the company also started rolling out its next-gen Powerwall 3 in markets around the world throughout last year. Along with Texas, Tesla currently has U.S. VPP programs being run or piloted in Northern and Southern California, Massachusetts, Puerto Rico and elsewhere, not to mention those in other multiple countries.
In November, Tesla’s team at Gigafactory Nevada also celebrated building over 1,000 Powerwall units in a single day. Months earlier in August, Giga Nevada crews reached a milestone of building 500 Powerwalls in one shift, as the company continues to ramp up production of the home-scale batteries.
Meanwhile, Tesla Energy’s portfolio is also backed by the Megapack grid-scale batteries, which have also been deployed worldwide. The company currently produces Megapacks at a factory in Lathrop, California, where it has been ramping production since launching in 2022, as well as a new facility in Shanghai, China, which went online last month. Tesla has also alluded to plans for a third “Megafactory,” which is reportedly being built in Texas.

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.
On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.
At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.
The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.
One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.
Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.
On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.
Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.
It is arguably as important as the software that drives it.
Tesla is set to inaugurate its dedicated Semi factory in Sparks, Nevada, this evening, but drone footage has already started to show who is expected on the handover stage.
Zanegler, a drone operator who regularly documents Tesla Semi operations in Nevada, filmed a row of new-generation Semi units parked outside of the plant with customer branding applied. The liveries visible in the video include companies like PepsiCo, U.S. Foods, Einride, DHL, WattEV, and others that have committed to utilizing Tesla’s Class 8 electric truck in their fleets.

Several of those company names already sit within Tesla’s public ordering book, including PepsiCo, which has been the program’s primary anchor customer since the first Semi deliveries in December 2022. PepsiCo now runs dozens of Tesla Semi units in daily service, with drivers completing regional routes.
Einride placed a 500-unit order in August, which was, at the time, the largest single Semi commitment. First deployments of their Semi units are planned for this month and will eventually span across California, Texas, New Jersey, Illinois, and Georgia. Meanwhile, IMC Logistics announced a 50-truck California order this week.

Other names, like LTS, OK Produce, and HMD, have not been widely confirmed as firm buyers, but their presence on the lot is perhaps the clearest signal that Tesla intends to expand on that list this evening at the event.
Tesla first unveiled the Semi back in 2017 with a 2019 production target.
Limited pilot builds reached PepsiCo in late 2022, and high-volume production began at the new 1.7-million-square-foot plant that sits logically positioned next to Tesla’s Gigafactory Nevada. Tesla Semi program director Dan Priestley has said that Tesla expects to build “many thousands” of Semi units this year, but as with every Tesla release, there have been set expectations of an S-curve ramp.
Outside estimates still put 2026 deliveries in the 5,000-to-15,000 range, but it will ultimately depend on Tesla’s readiness to put those units out, as well as how smoothly production is moving internally.
Tesla’s Semi Rollout event is set to start tonight at the Sparks factory, and it will be livestreamed on X starting at 6 p.m. PDT / 9 p.m. ET.
The Tesla App is now giving owners a better indication of what to expect when visiting a Supercharger site, as it is now sharing Site Maps in the app itself, making the feature no longer exclusively available in the car.
Tesla owners can now preview a Supercharger’s layout and live stall status from their phone thanks to the App’s new software version, v4.61.0. Zooming into a supported Supercharger on the charging map now switches the familiar street view into a site-specific map that shows stall positions, occupied bays, out-of-service posts, and a live count of open Superchargers.
It will even show you which specific Tesla model is charging at each occupied stall.

This is the same view drivers first saw inside the car with the 2025 Holiday Update, which started as a pilot for Tesla in California and Texas. Those early maps showed layout, nearby amenities, and the status of each operational stall. The feature has spread to most Superchargers in the U.S., but now Tesla wants the feature available through the Smartphone App, which is now rolling out to owners.
The in-vehicle screen maps remain a richer 3D canvas and originally required AMD Ryzen infotainment hardware, which left many Intel-based Model 3 and Model Y owners without the view. The app version removes that hardware barrier, so any owner can now get a preview of their upcoming Supercharger stop on their phone.
Anyone with the updated version of the app can open a Site Map on their phone. The feature has provided some additional peace of mind to anxious travelers and those who might be looking for a place that is less congested for faster charging speeds. It is a meaningful addition to many owners, especially for trips to unfamiliar locations.
You can now pick a Supercharger location that might be more aligned with what you are looking for or need: you can pick a site based on what stalls are open, where ADA stalls sit, how you will pull in, and more, instead of circling a crowded lot after arriving. Owners of older cars now have access to the feature without having to purchase a new vehicle altogether.
Site Mpas will not reserve a stall, nor will it change how Fast Charging works. Tesla does something simpler and more useful by giving owners a dedicated preview of the Supercharger they’re about to charge, turning an unknown parking lot into a place that may seem more familiar thanks to the preview.
