Rivian set to debut energy storage project using ‘second life’ batteries from vehicles
Rivian Automotive and the Honnold Foundation are working together in an initiative that is set to use the electric truck maker’s “second-life” batteries as stationary energy storage units in a microgrid project at Adjuntas, Puerto Rico. This marks a huge step for Rivian, which is planning on expanding its reach beyond the manufacture of all-electric luxury adventure vehicles.
Rivian will be utilizing 135 kWh battery packs from its development vehicles for the upcoming energy storage project, which is expected to launch in 2020. The company has designed its battery packs and modules in such a way that they can be easily transitioned from vehicle energy storage to stationary energy storage at the end of their vehicle life. The Rivian CEO described the concept in a press release.
“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency, and energy independence,” Scaringe said.
Using older batteries for energy storage is a clever way for Rivian to recycle the cells it uses for its all-electric trucks. While batteries at the end of their vehicle life will likely show some wear compared to those used in new EVs, they could still function well as stationary energy storage units. After all, optimal batteries for electric trucks require a lot of power, but those energy storage units could make do with much less (propelling the R1T from 0-60 mph, for example, takes a lot of power, but turning on the lights in a household does not require as much).
Rivian and the Honnold Foundation selected Adjuntas, Puerto Rico as the site of their microgrid project partly due to the town being in need of help. Adjuntas was struck by Hurricane Maria in 2017, and the community has been struggling with power since. If successful, Rivian and Honnold’s microgrid initiative could help many of the businesses located near the town’s main square. Residents could also have backup power in the event that power shortages happen.
Further details of the project will be discussed by RJ Scaringe and elite climber Alex Honnold at Denver, CO on June 15 in a livestreamed event, which could be accessed here.

DENVER, June 13, 2019 /PRNewswire/ — On June 15, electric adventure vehicle maker Rivian is announcing a project to use its second-life batteries in a solar microgrid initiative with the Honnold Foundation. The goal: to support energy independence and adoption of renewable power generation. The project, in the town of Adjuntas, Puerto Rico, marks Rivian’s first steps in its broad plan to utilize second-life batteries for a wide variety of applications.
Rivian CEO RJ Scaringe and elite climber Alex Honnold will discuss the project in Denver, Colorado on June 15 at 6PM MT. The conversation will be moderated by endurance athlete and podcaster Rich Roll. The livestream can be found here: https://www.youtube.com/c/RivianOfficial/live
The company is using 135kWh battery packs from its development vehicles to support the project.
Rivian has designed its pack, module, and battery management system to seamlessly transition from vehicle energy storage to stationary energy storage at the end of their vehicle life. The battery module’s thin design enables second-life applications that are space-efficient and customizable, important for environments with existing infrastructure.
“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency and energy independence,” said Scaringe.
Adjuntas is a city of 20,000 in midwestern Puerto Rico. It was severely impacted by Hurricane Maria in 2017, and with climate change increasing the frequency and severity of storms, Adjuntas NGO Casa Pueblo has sought to collaborate on rugged, affordable sources of community power.
The Honnold Foundation and Rivian battery engineers visited Casa Pueblo earlier in 2019 to meet with community leaders and together are designing a site-specific system that will power many of the businesses located in the Adjuntas town square. In power loss scenarios, the downtown solar microgrid will allow Adjuntas residents access to electricity for core businesses. By offsetting day-to-day electric bills, the system also brings down high commercial energy costs, which in Puerto Rico are twice the national average.
The system is expected to launch in 2020.

Trump’s invite for Elon just reshuffled Tesla’s big Signature Delivery Event
Tesla rescheduled its final Model S farewell to May 20 after Musk joined Trump in China.
Tesla has rescheduled its Model S and Model X Signature Edition delivery event to Wednesday, May 20, 2026, after abruptly calling off the original May 12 celebration. The event will take place at Tesla’s factory at 45500 Fremont Boulevard in Fremont, California, the same location where the Model S first rolled off the line in 2012. Invitees received a follow-up email asking them to reconfirm attendance and download a new QR code ticket, with Tesla noting that all travel and accommodation expenses remain the buyer’s responsibility.
The reason behind the original cancellation came into focus the same day it was announced. President Trump invited Elon Musk, Apple’s Tim Cook, BlackRock’s Larry Fink, Boeing’s Kelly Ortberg, and executives from Goldman Sachs, Blackstone, Citigroup, and Meta to join his trip to China this week for a summit with President Xi Jinping. The agenda covers trade, artificial intelligence, export controls, Taiwan, and the Iran war, following weeks of escalating friction between Washington and Beijing over AI technology, sanctions, and rare earth exports. Trump wrote on Truth Social, “I am very much looking forward to my trip to China, an amazing Country, with a Leader, President Xi, respected by all.”
Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
The vehicles at the center of all this are the last Model S and Model X units Tesla will ever build. Priced at $159,420 each, the 250 Model S and 100 Model X Signature Edition units come finished in Garnet Red with a one-year no-resale agreement, giving Tesla right of first refusal if the owner decides to sell. As Teslarati reported, the Model S defined Tesla’s early identity as a serious luxury automaker, and the Fremont factory line that built it is now being converted to manufacture Optimus humanoid robots.
Musk’s inclusion in the China delegation drew attention given his very public relationship with Trump, and the invitation signals the two have moved past and past grievances. Trump originally brought Musk on to lead the Department of Government Efficiency following his inauguration, and despite a sharp public dispute in mid-2025, the two have appeared together repeatedly in recent months. A seat on the China trip, the most diplomatically consequential visit of Trump’s current term, puts Musk back at the table on U.S. economic policy at a moment when Tesla’s China revenue remains one of the company’s most important financial pillars.
Tesla has launched a new solution to a rare but relevant Supercharger problem with a new Virtual Waitlist, a remedy that will solve sequencing confusion when there is a line to charge at one of the company’s locations.
Teslarati reported on what we called the Virtual Queue last month. In rare occurrences, there were physical altercations at Superchargers when someone might have cut in line to charge. Tesla started to develop some sort of system that would resolve this issue, and now it is finally rolling it out.
Tesla launches solution to end Supercharger fights once and for all
It will start with a Pilot Program, and Tesla is calling it the ‘Waitlist.’
Announced on May 11 on the official TeslaCharging X account, the pilot program is currently active at sites in Los Gatos, Mountain View, and San Francisco in California, as well as San Jose, CA, and the Bronx, NY (East Gun Hill Road). Drivers are encouraged to share feedback directly through the Tesla app to refine the system before a potential broader rollout.
We’re now testing a new waitlist feature at 5 Supercharger sites. Share feedback through the Tesla app to help us make it better.

– Mountain View, CA – El Monte Avenue
– San Francisco, CA – Lombard Street

Tesla released the video above to showcase the feature, which automatically joins the waitlist when your vehicle has the Supercharger with the wait as the destination in the navigation. There is also a notification that lets you know your place in line.
In this specific example, the video shows that the wait is less than five minutes, and that there are two cars ahead of the one in the video:

Having a wait at a Supercharger is relatively rare, but it does happen. It is even more frequent now that there are more EVs allowed to use the Supercharger Network. Those non-Tesla EVs can also join the queue, as Tesla added in its social media release of the pilot program that they can join the waitlist using the Tesla app.
The release of this program should help alleviate the rare risk of incidents at Superchargers. Tesla will expand this program as it sees fit, and it gathers valuable data and reviews from users.
Investor's Corner
Tesla Optimus is already benefiting investors, top Wall Street firm says
Piper Sandler has updated its detailed valuation model for Tesla (NASDAQ: TSLA), concluding that at recent share prices around $400–$420, investors are essentially acquiring the company’s ambitious Optimus humanoid robot project at no extra cost.
Tesla Optimus is already benefiting investors from a fiscal standpoint, at least that is what Alexander Potter at Piper Sandler, a top Wall Street firm covering the company, says.
Piper Sandler has updated its detailed valuation model for Tesla (NASDAQ: TSLA), concluding that at recent share prices around $400–$420, investors are essentially acquiring the company’s ambitious Optimus humanoid robot project at no extra cost.
Analyst Alexander Potter, in the firm’s latest “Definitive Guide to Investing in Tesla,” built a comprehensive framework covering 17 separate product lines.
This granular approach values Tesla’s core businesses—including electric vehicles, energy storage, Full Self-Driving (FSD) software, in-house insurance, Supercharging network, and a standalone robotaxi operation—at approximately $400 per share, without assigning any value to Optimus or related inference-as-a-service opportunities.
“At $400/share, we think investors can buy Optimus for ‘free,’” Potter stated in the note. Piper Sandler maintained its Overweight rating on Tesla shares and a $500 price target, which implicitly attributes roughly $100 per share to the robot-related businesses— a figure the analyst views as potentially conservative.
The updated model incorporates elements often overlooked by other sell-side analysts, such as detailed forecasts for Tesla’s insurance operations, Supercharger revenue, and a distinct valuation for the robotaxi business separate from FSD software licensing. It also accounts for Tesla’s 2025 CEO compensation plan for the first time.
Potter acknowledged that his estimates for 2026 and 2027 fall below Wall Street consensus, citing factors like declining deliveries from certain discontinued models and reduced regulatory credit income.
However, he expressed limited concern, noting that traditional vehicle delivery metrics are expected to matter less over time as FSD subscriber growth and robotaxi deployment metrics gain prominence. On Optimus specifically, Potter suggested the humanoid robot program, combined with inference services, “arguably will be worth more than Tesla’s other businesses combined,” though the firm has not yet produced formal long-term forecasts for these segments.
Tesla shares have traded near the $400 range in recent sessions, reflecting ongoing investor focus on the company’s autonomous driving progress and expansion into robotics and AI. The Optimus project remains in early development stages, with Tesla aiming to deploy the robots initially for internal factory tasks before broader commercial applications.
This Piper Sandler analysis highlights the growing emphasis among some investors and analysts on Tesla’s long-term technology platform potential beyond its current automotive and energy businesses.
As with any forward-looking valuation, outcomes will depend on execution timelines, technological breakthroughs, regulatory approvals for autonomous systems, and market adoption of humanoid robotics—areas that carry significant uncertainty and execution risk.
The note underscores a common theme in Tesla coverage: differing views on how to quantify emerging high-growth opportunities like robotics within the company’s overall enterprise value. Investors are advised to consider their own risk tolerance and conduct thorough due diligence regarding these speculative elements.
