Tesla Energy is quietly setting its sights on peaker plants
Behind the spotlights trained on the Model 3 production ramp and Elon Musk’s online behavior, Tesla’s Energy business is quietly growing and spreading its reach. Tesla notes that its deployment of stationary batteries, which are designed to supply electricity to residential homes, businesses, and even the power grid, surged 450% in the first six months of 2018 alone. These figures are well in line with Elon Musk’s statement during the Q2 2018 earnings call, when he noted that Tesla Energy is growing at such a pace that it would likely catch up and exceed the company’s electric car business in the future.
During the 2018 Annual Shareholder Meeting, Elon Musk announced that Tesla managed to hit a milestone of installing 1 GWh of energy storage to projects worldwide. This is only the beginning, though, as the company is aiming to double its battery storage installations within the next 12 months. Just like its electric cars like the Model 3, Tesla’s energy products like the Powerwall 2 home battery system are seeing overwhelming demand from customers — so much so that installations for the products are quite delayed. In Tesla’s website alone, the company notes that new Powerwall 2 orders would likely not be filled until “late 2018” at the earliest.
Despite the company currently being unable to meet production, Tesla CTO JB Straubel noted in a recent statement to the San Francisco Chronicle that Tesla’s battery production would likely catch up early next year. Straubel stated that while Tesla is scaling production as fast as it could, there are still delays as the demand for the residential market continues to be larger than expected. Demand from utility providers has remained strong as well. Back in June, for example, the company landed a contract with Pacific Gas and Electric Co. to install its industrial-grade Powerpack batteries to store 730 MWh of electricity in Moss Landing; and that’s just one of several high-profile projects that the company is engaged in.

Tesla’s energy storage solutions are starting become more and more accepted by utility companies, particularly since battery technology has reached a point where it now has the potential to replace inefficient and dirty “Peaker” power plants, which are powered on when the demand for electricity is at its highest. Straubel believes that battery solutions such as those offered by Tesla Energy are poised to outcompete conventional peaker plants.
“I think what we’ll see is we won’t build many new peaker plants, if any. Already what we’re seeing happening is the number of new ones being commissioned is drastically lower, and batteries are already outcompeting natural gas peaker plants,” Straubel said.
Tesla Energy’s initiative to eventually replace peaker power plants is very similar to the company’s efforts to render fossil fuel-powered automobiles obsolete. Elon Musk is known to have said that Tesla will not stop “until every car on the road is electric.” Considering the CTO’s recent statements, it appears that Tesla Energy would likely not stop until all backup power plants are powered by renewable energy as well.
Tesla will actually be doing the world a favor if its Energy business ends up helping in the transition of the power industry away from peaker plants. Peaker plants, after all, are responsible for a lot of pollution. A case study of the facilities in CA cited by the Clean Energy Group noted that peaker plants emit roughly 30% more carbon dioxide per megawatt-hour than natural gas combined-cycle plants, which are increasingly being used as base load plants. The case study also noted that 84% of peaker plants are located in areas that are vulnerable to environmental damage. On top of this, peaker plants are actually quite costly for consumers, considering that they are utilized when demand for electricity is at its highest.

Tesla Energy’s goal of eventually replacing peaker plants might be ambitious, but it is not impossible, especially since the United States’ energy storage business has been seeing growth over the past years. A study from GTM Research, for one, estimates that the sales of energy storage for both residential and utility markets in the US would likely hit $541 million this year, before passing $1 billion in 2019, and hitting $4.6 billion in 2023. If Tesla can ramp its energy business within the coming years, the company could position itself strategically in what could very well be an upcoming energy gold rush.
Tesla’s energy business usually takes a back seat to the company’s electric car division, but the updates that the company has teased regarding its battery technology are very encouraging. During the 2018 Annual Shareholder Meeting, for one, Elon Musk mentioned that Tesla is now aiming to hit a cost of $100 per kWh at the pack level.
“We think at the cell level probably we can do better than $100/kWh maybe later this year depending upon stable commodity prices. With further improvements to the cell chemistry, the production process, and more vertical integration on the cell side, for example, integrating the production of cathode and anode materials at the Gigafactory, and improved design of the module and pack, we think long-term we can get below $100/kWh at the pack level,” he said.

Tesla VP hints at Solar Roof comeback with Giga New York push
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla’s long-awaited and way underrated Solar Roof may finally be getting its moment. During the company’s Q3 2025 earnings call, Vice President of Energy Engineering Michael Snyder revealed that production of a new residential solar panel has started at Tesla’s Buffalo, New York facility, with shipments to customers beginning in the first quarter of 2026.
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla Energy’s strong demand
Responding to an investor question about Tesla’s energy backlog, Snyder said demand for Megapack and Powerwall continues to be “really strong” into next year. He also noted positive customer feedback for the company’s new Megablock product, which is expected to start shipping from Houston in 2026.
“We’re seeing remarkable growth in the demand for AI and data center applications as hyperscalers and utilities have seen the versatility of the Megapack product. It increases reliability and relieves grid constraints,” he said.
Snyder also highlighted a “surge in residential solar demand in the US,” attributing the spike to recent policy changes that incentivize home installations. Tesla expects this trend to continue into 2026, helped by the rollout of a new solar lease product that makes adoption more affordable for homeowners.
Possible Solar Roof revival?
Perhaps the most intriguing part of Snyder’s remarks, however, was Tesla’s move to begin production of its “residential solar panel” in Buffalo, New York. He described the new panels as having “industry-leading aesthetics” and shape performance, language Tesla has used to market its Solar Roof tiles in the past.
“We also began production of our Tesla residential solar panel in our Buffalo factory, and we will be shipping that to customers starting Q1. The panel has industry-leading aesthetics and shape performance and demonstrates our continued commitment to US manufacturing,” Snyder said during the Q3 2025 earnings call.
Snyder did not explicitly name the product, though his reference to aesthetics has fueled speculation that Tesla may finally be preparing a large-scale and serious rollout of its Solar Roof line.
Originally unveiled in 2016, the Solar Roof was intended to transform rooftops into clean energy generators without compromising on design. However, despite early enthusiasm, production and installation volumes have remained limited for years. In 2023, a report from Wood Mackenzie claimed that there were only 3,000 operational Solar Roof installations across the United States at the time, far below forecasts. In response, the official Tesla Energy account on X stated that the report was “incorrect by a large margin.”

Tesla China’s Megafactory helps boost Shanghai’s battery exports by 20%: report
Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February.
Reports from China have indicated that the Tesla Shanghai Megafactory has become a notable player in China’s booming battery export market.
Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February. It produces Tesla Megapack batteries for domestic and international use.
Tesla Shanghai Megafactory
As noted in a report from Sina Finance, the Tesla Shanghai Megafactory’s output of Megapack batteries helped drive a notable rise in lithium battery shipments from the city in the first three quarters of 2025. This is quite impressive as the Megafactory is a rather young facility, though it has been steadily increasing its production capacity.
“The establishment of this benchmark factory has not only driven the rapid development of Shanghai’s energy storage industry but also become a new growth engine for foreign trade exports. Driven by the Tesla energy storage factory’s opening, Shanghai’s lithium battery exports reached 32.15 billion yuan ($4.5 billion) in the first three quarters, a 20.7% increase,” the publication wrote.
Ultimately, the Shanghai Megafactory has proved helpful to the city’s “new three” industries, which are comprised of new energy vehicles, lithium batteries, and photovoltaic systems. Exports of the “new three” products reached 112.17 billion yuan ($15.7 billion), a 6.3% year-over-year increase during the same period. The city’s total trade volume grew 5.4% year-over-year as well, with exports up 11.3%, driven largely by the clean energy sector’s performance.
Energy storage is helping Shanghai
Since opening in February, the Shanghai Megafactory has been firing on all cylinders. In late July, Tesla Energy announced that the new battery factory has successfully produced its 1,000th Megapack unit. That’s quite impressive for a facility that, at the time, had only been operational for less than six months.
Speed has always been a trademark of the Shanghai Megafactory. Similar to Tesla’s other key facilities in China, the Megafactory was constructed quickly. The facility started its construction on May 23, 2024. Less than a year later, the site officially started producing Megapack batteries. By late March 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.

Tesla recalls Powerwall 2 units in Australia
Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.
Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.
Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.
The issue is related to the cells, which Tesla sources from a third-party company.
Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.
