Tesla’s Energy business, while not attracting as many headlines as the company’s electric car division, continues to expand its reach. While some of Tesla Energy’s projects fly practically under the radar, the company’s lithium-ion battery storage units have, quite literally, changed lives across the globe.
When Tesla announced its first quarter results last week, the company noted that it is streamlining its residential energy storage business with a simplified online sales channel. The company also stated that it expects to grow its Energy business this year, as it works through the backlog of Powerwall orders that have been, for the most part, put aside in favor of the company’s ramp for the Model 3 in 2018.
“Energy generation and storage revenue should increase significantly in 2019. This increase is driven mainly due to the storage business as we increase production to address our backlog in Powerwall orders and deliver on our pipeline of orders for commercial storage and an expected growth in retrofit solar deployments in the second half of 2019,” Tesla noted.
One of these Tesla Energy orders could be found in Eritrea, a country in the Horn of Africa. Tesla was involved in two projects in the nation, particularly in Areza and Maidma, where it played a crucial role in establishing a 1.25MW and 1MW mini-grid for the rural communities. The projects were led by UK solar developer Solarcentury, who opted to utilize Tesla’s lithium-ion batteries as the energy storage units of choice for the mini-grid. Overall, the project benefitted around 40,000 people and businesses, which will now be getting cheaper and more stable power.
Prior to the installation of its solar panels and Tesla batteries, the communities in Areza and Maidma relied solely on diesel. With the mini-grid in place, the residents of the African nation will be able to step away from inconveniences such as fluctuating diesel prices, steep maintenance costs of its diesel equipment, and reduced air quality. Theo Guerre-Canon, a project manager at Solarcentury, described the mini-grid’s benefits in a statement to Forbes. “Our hope is that access to reliable electricity will support wider economic growth in the region and social development. For example, there’s a clinic in Areza that will now benefit from uninterrupted electricity,” he said.
This is not the first time that Tesla’s batteries have literally changed the lives of communities for the better. In the Philippines, Tesla worked with a solar provider to install a microgrid in a town that’s notorious for never having 24/7 power. Since coming online, Tesla’s batteries have affected many of the town’s residents. Fishermen, for example, are now able to freeze their catch and sell them to towns that are farther away, resulting in more income. These benefits might seem trivial to many, but for residents who have been conditioned to think of power interruptions as part of everyday life, having round-the-clock electricity thanks to Tesla’s batteries is remarkable.
Now that Tesla has all but mastered Model 3 production, the company appears to be finally ready to push its Energy business more aggressively. This was teased by Elon Musk himself during the unveiling of the Tesla Model Y, where he noted that 2019 would be the “Year of the Solar Roof and Powerwall.” Musk also highlighted how Tesla Energy is invaluable to the company’s mission. “Solar plus battery plus electric vehicles, we have a fully sustainable future. That’s a future you can feel really excited and optimistic about. I think that really matters,” Musk said. For the communities that have been changed and helped by Tesla’s batteries, these words definitely ring true.

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.
