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 Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale
The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
