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.

Google just picked SpaceX for its first step into orbital AI
Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.
Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.
The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.
The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.
MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.
SpaceX and Google mull massive partnership on Musk’s orbital data dream: report
Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.
The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.
Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”
Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

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.
