Tesla Megapacks are set to back a new energy storage facility in Puerto Rico, after officials from the territory’s government and from the company met last week to sign a contract for the deal.
As detailed in a press release from project partner Genera PR, Tesla has signed a contract for a 430MW/ 1,720MWh Megapack project across six different power plant locations in Puerto Rico. Tesla’s Director of Megapack Americas Brad Harbidge was joined by Genera CEO and President Winnie Irizarry, Governor Jenniffer González Colón, and other officials for a contract signing event last Friday.
“We are addressing the energy crisis by taking action to stabilize the system and ensure a reliable, modern, and accessible electric service for all,” said González Colón. “The signing of the contract for the acquisition of 430 MW in Energy Storage Systems, which does not cost the people as it comes from federal funds, does not increase emissions, is part of the movement toward new energy sources, and can greatly reduce power outages.”
The Megapacks will be deployed to sites at power generation plants in the following locations:
- Cambalache, Arecibo
- Vega Baja
- Palo Seco, Toa Baja
- Yabucoa
- Aguirre, Salinas
- Costa Sur
Initial Megapacks are set to begin arriving in Cambalache in July, while the parties expect the entire distributed system to become operational by the first quarter of 2027.
On Monday, González Colón also shared additional photos from the Friday meeting on X, which you can see below.

“The new energy storage systems will allow for the integration of 430 MW of clean, instantly dispatchable energy for up to four hours, resulting in an expected 90-percent reduction in load shedding,” Irizarry said.
Officials selected Tesla’s four-hour Megapacks for the project in October, prior to finalizing the contract at the signing event. The groups have also said that they expect the total investment into the project to reach $767 million, likely including everything from the purchase price of the Megapacks, to construction and labor.
The capacity level for the 430MW project is also considered to be the equivalent of the largest power plant currently operating in Puerto Rico, according to the release.
“The signing of this agreement with Tesla represents a momentous change in Puerto Rico’s energy transformation. This unprecedented investment in our energy infrastructure is a firm step toward a sustainable future,” Irizarry adds.
Tesla also launched its latest-generation Powerwall home battery, the Powerwall 3, in Puerto Rico in December, after beginning to roll the new hardware out to a number of markets throughout last year. While Megapacks are Tesla’s product for grid-scale energy storage, Powerwalls are a suitable size for homes and businesses hoping to keep the lights on during outages through charging from the grid or from renewable sources such as solar.
Using the Powerwall batteries, Tesla has also launched its Virtual Power Plant (VPP) program in Puerto Rico alongside these programs in a handful of U.S. states. The VPP programs effectively create a giant, distributed battery from Powerwall owners across a given region, letting them sell their stored electricity back to the grid during times of peak use or outages.

Tesla Robotaxi has already surpassed Waymo in this key metric
Tesla Robotaxi has already overtaken Waymo in Austin in one key metric, but there’s still more work to do.

Tesla Robotaxi has already surpassed Waymo in one extremely important key metric: size of service area.
Tesla just expanded its service area in Austin on Monday morning, pushing the boundaries of its Robotaxi fleet in an interesting fashion with new capabilities to the north. Yes, we know what it looks like:
🚨 Tesla’s new Robotaxi geofence is…

The expansion doubled Tesla Robotaxi’s potential travel locations, which now include the University of Texas at Austin, a school with over 53,000 students.
The doubling of the service area by Tesla has already made its travel area larger than Waymo’s, which launched driverless rides in October 2024. It became available to the public in March 2025.
According to Grok, the AI agent on X, Tesla Robotaxi’s current service area spans 42 square miles, which is five square miles larger than Waymo’s service area of 37 square miles.

Much can be said about the shape… but the Robotaxi area is now ~3.9 mi² (10 km²) larger than Waymo’s!! pic.twitter.com/dVfh2ODxJC

The service area is one of the most important metrics in determining how much progress a self-driving ride-hailing service is making. Safety is the priority of any company operating a ride-hailing network, especially ones that are making it a point to use autonomy to deploy it.
However, these companies are essentially racing for a larger piece of the city or cities they are in. Waymo has expanded to several different regions around the United States, including Arizona and Los Angeles.
Tesla is attempting to do the same in the coming months as it has already filed paperwork in both California and Arizona to deploy its Robotaxi fleet in states across the U.S.
As the platform continues to show more prowess and accuracy in its operation, Tesla will begin to expand to new areas, eventually aiming for a global rollout of its self-driving service.

Tesla Megapacks arrive for massive battery replacing coal plant
Tesla Megapacks have started arriving on-site to the Stanwell Battery Project, just as Queensland prepares to wind down the Stanwell coal plant.

The first of over 300 Tesla Megapacks have arrived to the site of a massive battery energy storage system (BESS) being built in Australia, dubbed the Stanwell Battery Project after a coal plant it’s set to replace.
In a press release last week, the Stanwell Battery Project announced that the first Tesla Megapack 2XL units had arrived to the site, which is located outside of Rockhampton in Queensland, Australia. The project will eventually feature 324 Megapack units, set to arrive in the coming months, in order to support the 300MW/1,200MWh battery project.
“The Stanwell Battery is part of the diversification of our portfolio, to include cleaner and more flexible energy solutions,” said Angie Zahra, Stanwell Central Generation General Manager. “It is just one part of the 800 MW of battery energy storage capacity we have in our pipeline.
“Capable of discharging 300 MW of energy for up to four hours (1,200 MWh), our mega battery will be one of the largest in Queensland.”

READ MORE ON TESLA MEGAPACKS: Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The state is working with government-owned company Yurika to facilitate construction, and the process is expected to create roughly 80 jobs. The project is expected to come fully online in May 2027, with initial commissioning of the Megapacks aiming for November 2025.
The Stanwell Battery is set to replace the nearby Stanwell coal generation plant, which the government is planning to wind down starting in 2026 as part of efforts to reach an 80 percent renewable energy generation ratio by 2035. Meanwhile, the government is also set to begin winding down the Tarong and Callide coal plants, while several other Megapack projects are being built or coming online. o ya
Tesla currently has two Megapack production facilities, located in Lathrop, California, in the U.S. and another that came online earlier this year in Shanghai, China. The Shanghai Megafactory shipped its first units to Australia in March, while both factories are expected to be capable of producing 10,000 Megapack units per year upon reaching volume production.

The Tesla Diner is basically finished—here’s what it looks like
The company first broke ground on the Diner, Drive-in, and Supercharger location in September 2023. Now, it has served one of its first internal customers.

Tesla has finally completed the construction of its highly anticipated Diner, Drive-in, and Supercharger in Los Angeles, and recent photos of the interior’s “retro-futuristic” style are making their way around the internet.
X user Brad Goldberg shared photos from the Tesla Diner site last Tuesday, depicting some of the Supercharger stalls, indoor and outdoor seating areas, multiple neon lights, and even an Optimus robot. Goldberg also noted that there had been a “flurry of activity on site” while he was snapping the photos last week, suggesting that the restaurant location could be getting close to opening.
The Tesla Diner also served one of its first internal customers in the past few days, as Elon Musk posted on X on early Monday morning that he had just finished up eating a meal at the site:
I just had dinner at the retro-futuristic Tesla diner and Supercharger.
Team did great work making it one of the coolest spots in LA!
The photos also show that the site is pretty much done, with some of them even showing vehicles charging at the charging stalls.
You can see some of the latest photos of the Tesla Diner below.

When will the Tesla Diner open to external customers?
While it’s still not open to external customers yet, the news again suggests that the company could be close to an official opening date. Tesla first broke ground on the Diner in September 2023, after receiving a wave of building permit approvals throughout that year. Teslarati also covered much of the construction progress throughout last year, including when crews installed the first and second drive-in screens.
Located at 7001 West Santa Monica Boulevard, the idea was first discussed in 2018 by Musk and a few others on Twitter, featuring 1950s rock and roll, waiters on roller skates, and drive-in movie theater screens playing clips from some of history’s best movies. Notably, the photos of the front doors also show that the site will be open 24 hours a day, 7 days a week, whenever it does end up opening.
