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.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
