Tesla responds to Amazon fire report, says remaining solar installations are optimal
On the heels of Walmart’s recent lawsuit against Tesla Energy laying claim to 7 fires allegedly caused by Tesla’s solar panel installations, Amazon has now claimed that it also experienced a fire in June 2018 with the same company as culprit. The online retailer has also indicated that it has taken steps to mitigate future issues and that no further projects are planned using Tesla solar panels.
A Tesla spokesperson has provided a statement about Amazon’s claims, stating that necessary steps have been taken to ensure that the e-commerce giant’s remaining Tesla solar installations are functioning as safe and reliably as possible. The representative also noted that the fire reported by Amazon was an isolated incident.
“All 11 Amazon sites with solar from Tesla are generating energy and are proactively monitored and maintained. Last year, there was an isolated event that occurred in an inverter at one of the Amazon sites. Tesla worked collaboratively with Amazon to root cause the event and remediate. We also performed inspections at the other sites, which confirmed the integrity of the systems. As with all of our commercial solar installations, we continue to proactively monitor the systems to ensure they operate safely and reliably,” Tesla noted.
Amazon, for its part, has not issued a response to Tesla’s statement as of writing.
Tesla’s statement about Amazon’s solar fire report comes as the company’s litigation with Walmart remains ongoing. A joint statement was put forth by the companies since the initial Complaint was filed, indicating their desire to find a resolution.
“Walmart and Tesla look forward to addressing all issues and re-energizing Tesla solar installations at Walmart stores, once all parties are certain that all concerns have been addressed. Together, we look forward to pursuing our mutual goal of a sustainable energy future. Above all else, both companies want each and every system to operate reliably, efficiently, and safely,” the two companies wrote.
Given the heated nature of both Tesla’s and Walmart’s positions on the issues, the joint statement may not have much real-world effect; however, neither party likely wants all of their internal issues deliberated in a litigated public forum. For instance, the deposition phase may reveal Walmart is quite negligent in their rooftop maintenance and had more of a financial interest in breaking its contract with Tesla than repairing the issues representing a miniscule percentage of its solar installations.
Other activities related to the solar panel fires look as though they may be related to Tesla’s “Project Titan” undertaking wherein 1% of third-party parts were found to have exhibited abnormal behavior. A Tesla representative explained that Tesla’s software-monitoring applications found that a small number of Amphenol H4 connectors experienced failures and disconnections higher than their standards allowed. Since the connectors regulate the flow of energy and heat to the solar panels, failures from this part can lead to overheating and fires.
“A portion of SolarCity-installed modules and optimizers from various manufacturers were made with H4 connectors from Amphenol, a part that was commonly used across the industry at the time,” the Tesla representative was quoted as saying. Project Titan’s primary objective was to refurbish or replace this part with MC4 connectors as a remediation effort to preemptively address potential issues. As of April 2019, Project Titan was still underway.

Tesla launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid
You’re making £££ and the community is powered by clean energy

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.
The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.
Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.
