Tesla Powerwall 2 is completely dominating the US home energy storage market: report
A recently-published report from EnergySage, an online comparison-shopping marketplace for rooftop solar and energy storage systems, has revealed something quite incredible. Despite Tesla Energy’s understated ramp, the Powerwall 2 has actually been dominating the United States’ residential battery storage market — and the competition is not even close.
Tesla Energy’s domination is due in no small part to the Powerwall 2’s pricing, which makes it the least expensive storage option on a per-kWh stored basis.
The findings about Tesla’s humble residential battery unit were shared by EnergySage in its eleventh semiannual Solar Marketplace Intel Report, which covers the 12-month period from July 2019 to June 2020. This time around, the company decided to look into transaction-level battery storage data from its Solar Marketplace. These included information about energy storage solutions that are usually being quoted to homeowners.
Based on EnergySage’s report, over half of the battery storage quotes in the platform included a Tesla Powerwall. This made Tesla’s humble residential battery unit the most-quoted battery storage option in the platform by a wide margin.
As noted in a report from PV Magazine USA, part of the reason behind the Powerwall 2’s domination of the energy storage segment is Tesla’s aggressive pricing, which undercuts competitors to a significant degree. On a cost per kWh stored basis, Tesla offers the cheapest battery storage option in EnergySage’s Marketplace, with its strongest competitor, LG Chem, offering alternatives that are over 30% more expensive. Other competitors are far more disadvantaged against the Powerwall 2 on a cost per kWh basis.
“To date, the two most widely quoted storage brands on the EnergySage Marketplace are Tesla and LG Chem, in line with installation data from California’s Self Generation Incentive Program (SGIP) over the last few years. Presently, over half of all quotes on EnergySage are for the Tesla Powerwall 2. Looking at installed costs, Tesla is also the lowest cost offering on a dollar per kilowatt-hour ($/kWh) basis. Interestingly, two companies who use lithium iron phosphate (LFP) battery chemistries–Enphase and sonnen–see the highest $/kWh costs in the Marketplace,” the report noted.
The Powerwall 2 may be Tesla’s most humble battery storage unit, but it holds a lot of potential. Boasting an integrated DC/AC converter, off-grid capabilities, and mobile app support, the Powerwall 2 has all the elements of a classic Tesla product. The battery unit, just like the company’s electric cars, receives over-the-air updates, optimizing its performance and adding new features. Among these is Storm Watch, which maximizes energy storage during inclement weather and other conditions that may threaten the power grid.

Tesla Energy celebrates one decade of sustainability
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.

Tesla Energy recently celebrated its 10th anniversary with a dedicated video showcasing several of its milestones over the past decade.
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy Early Days
When Elon Musk launched Tesla Energy in 2015, he noted that the business is a fundamental transformation of how the world works. To start, Tesla Energy offered the Powerwall, a 7 kWh/10 kWh home battery system, and the Powerpack, a grid-capable 100 kWh battery block that is designed for scalability. A few days after the products’ launch, Musk noted that Tesla had received 38,000 reservations for the Powerwall and 2,500 reservations for the Powerpack.
Tesla Energy’s beginnings would herald its quiet growth, with the company later announcing products like the Solar Roof tile, which is yet to be ramped, and the successor to the Powerwall, the 13.5 kWh Powerwall 2. In recent years, Tesla Energy also launched its Powerwall 3 home battery and the massive Megapack, a 3.9 MWh monster of a battery unit that has become the backbone for energy storage systems across the globe.
Key Milestones
As noted by Tesla Energy in its recent video, it has now established facilities that allow the company to manufacture 20,000 units of the Megapack every year, which should help grow the 23 GWh worth of Megapacks that have already been deployed globally.
The Powerwall remains a desirable home battery as well, with more than 850,000 units installed worldwide. These translate to 12 GWh of residential entry storage delivered to date. Just like the Megapack, Tesla is also ramping its production of the Powerwall, allowing the division to grow even more.
Tesla Energy’s Role
While Tesla Energy does not catch as much headlines as the company’s electric vehicle businesses, its contributions to the company’s bottom line have been growing. In the first quarter of 2025 alone, Tesla Energy deployed 10.4 GWh of energy storage products. Powerwall deployments also crossed 1 GWh in one quarter for the first time. As per Tesla in its Q1 2025 Update Letter, the gross margin for the Energy division has improved sequentially as well.

Tesla Energy shines with substantial YoY growth in deployments

Tesla Energy shined in what was a weak delivery report for the first quarter, as the company’s frequently-forgotten battery storage products performed extraordinarily well.
Tesla reported its Q1 production, delivery, and deployment figures for the first quarter of the year, and while many were less-than-excited about the automotive side, the Energy division performed well with 10.4 GWh of energy storage products deployed during the first quarter.
This was a 156 percent increase year-over-year and the company’s second-best quarter in terms of energy deployments to date. Only Q4 2024 was better, as 11 GWh was recorded.
Tesla Energy is frequently forgotten and not talked about enough. The company has continued to deploy massive energy storage projects across the globe, and as it recorded 31.5 GWh of deployments last year, 2025 is already looking as if it will be a record-setting year if it continues at this pace.

Although Energy performed well, many investors are privy to that of the automotive division’s performance, which is where some concern lies. Tesla had a weak quarter for deliveries, missing Wall Street estimates by a considerable margin.
There are two very likely reasons as to why this happened: the first is Tesla’s switchover to the new Model Y at its production facilities across the globe. Tesla said it lost “several weeks” of production due to the updating of manufacturing lines as it rolled out a new version of its all-electric crossover.
Secondly, Tesla could be facing some pressure from pushback against the brand, which is what many analysts will say. Despite the publicity of attacks on Tesla drivers and their vehicles, as well as the company’s showrooms, it would be safe to assume that we will have a better picture painted of what the issue is in Q2 after the company reports numbers in July.
If Tesla is still struggling with lackluster delivery figures in Q2 after the Model Y is ramped and deliveries are more predictable and consistent, we could see where the argument for brand damage is legitimate. However, we are more prone to believe the Model Y, which accounts for most of Tesla’s sales, and its production ramp is likely the cause for what happened in Q1.
In what was a relatively bleak quarter, Tesla Energy still shines as the bright spot for the quarter.

Tesla lands in Texas for latest Megapack production facility

Tesla has chosen the location of its latest manufacturing project, a facility that will churn out the Megapack, a large-scale energy storage system for solar energy projects. It has chosen Waller County, Texas, as the location of the new plant, according to a Commissioners Court meeting that occurred on Wednesday, March 5.
Around midday, members of the Waller County Commissioners Court approved a tax abatement agreement that will bring Tesla to its area, along with an estimated 1,500 jobs. The plant will be located at the Empire West Industrial Park in the Brookshire part of town.
Brookshire also plans to consider a tax abatement for Tesla at its meeting next Thursday.
The project will see a one million square-foot building make way for Tesla to build Megapack battery storage units, according to Covering Katy News, which first reported on the company’s intention to build a plant for its energy product.
CEO Elon Musk confirmed on the company’s Q4 2024 Earnings Call in late January that it had officially started building its third Megapack plant, but did not disclose any location:
“So, we have our second factory, which is in Shanghai, that’s starting operation, and we’re building a third factory. So, we’re trying to ramp output of the stationary battery storage as quickly as possible.”

The Megapack has been a high-demand item as more energy storage projects have started developing. Across the globe, regions are looking for ways to avert the loss of power in the event of a natural disaster or simple power outage.
This is where Megapack comes in, as it stores energy and keeps the lights on when the main grid is unable to provide electricity.
Vince Yokom of the Waller County Economic Development Partnership, commented on Tesla’s planned Megapack facility:
“I want to thank Tesla for investing in Waller County and Brookshire. This will be a state-of-the-art manufacturing facility for their Megapack product. It is a powerful battery unit that provides energy storage and support to help stabilize the grid and prevent outages.”
Tesla has had a lease on the building where it will manufacture the Megapacks since October 2021. However, it was occupied by a third-party logistics company that handled the company’s car parts.
