Megapack excels in off-grid and on-grid applications, supplying large data center loads, buffering oscillating demand, helping interconnection grid-compliance and strengthening the grid - all with less local fossil generation
Megapack is @NVIDIAAIInfra DSX Ready
Announcing NVIDIA DSX Ready, a qualification program for partner products and solutions that meet NVIDIA DSX AI factory reference design requirements.
NVIDIA DSX Ready will help AI factory builders evaluate offerings with greater confidence, reduce risk, and accelerate deployment.
The program launches with qualified battery energy storage system (BESS) and cooling distribution unit (CDU) solutions from @hitachienergy, @LGUS, LG Energy Solution, @liquid_stack, @Tesla_Megapack, and @Vertiv.

Australia's first 8-hour long-duration battery is now operating in Limondale, NSW
Built by RWE, 144 Tesla Megapacks charge 2x faster than discharge = more daytime renewables stored to cover evening peaks & into the night
Megapack is designed for fast and simple deployment
Watch how our products go from factory through installation to get connected to the grid
Megapack 3 is officially rolling off the line at our newest Megafactory in Brookshire, Texas!
The factory went from groundbreaking to operation in just 16 months & has a designed capacity of 50 GWh/year dedicated to Megapack 3
Our first Megapacks with Made-in-America LFP cells are on their way to customers! 🇺🇸
These domestic cells are manufactured at our facility in Sparks, Nevada and integrated into Megapacks from our Megafactory in California. This is a significant milestone for domestic cell manufacturing and energy security
Autobidder, our battery optimization service, is maximizing the value of one of France’s largest battery storage projects
The Chevire project was developed by @Harmony_Energy_ on the site of a former coal power plant and is providing clean and reliable power to the local area
The first utility-scale Megapack project in New Zealand is now operating!
56 Megapacks at @ContactEnergy Glenbrook-Ohurua Battery 1 are providing 100 MW / 200 MWh of reliable and affordable energy to the region
The site was commissioned ahead of schedule and Battery 2 is officially underway
10 GWh of our industrial energy storage products are now operating across Australia!
That's equivalent to 160,000 Model Ys. And we're just getting started

Our mission is to build a world of amazing abundance.
Highlights from our 2025 Impact Report below
Tesla.com/Impact
Last year, 10 of the 17 new utility-scale projects in Australia were Megapack
Delivering 4,130 MWh, these accounted for >50% of the total projects reaching commercial operation

23 years ago, we set out to prove that electric cars could be great – not just great electric cars, but the best cars overall.
We’ve gone from one electric sports car to
– Over 9 million vehicles on the road
– Model Y becoming the world’s best-selling car of any kind only 3 years after first deliveries
– 5 Gigafactories & other manufacturing sites across 3 continents
– The largest & most reliable fast charging network w/ over 80,000 Superchargers globally
– Energy generation & storage systems helping power homes & grids (over 1 million Powerwalls installed, 70+ GWh of industrial energy storage operating globally across 2,200+ projects)
Today, we’re bringing AI into the real world with autonomy @teslasi and robotics @Tesla_Optimus.
Tesla is only getting started – a world of amazing abundance awaits
Megablock lands in Germany!⚡️
Recap of Mega Munich where our team hosted customers for technical deep dives on everything from fire safety, to grid compliance, and controls
25+ GWh of Megapack to be deployed across Europe 💥
A turning point for NatPower.
Two great teams working together to build the energy infrastructure required for the next generation of growth.

Megapack + Autobidder will soon be online in the east of France!
The 240 MW / 480 MWh Cernay-lès-Reims site is being developed by TagEnergy and will be one of the largest batteries in France
Tesla is providing full scope Engineering, Procurement and Construction (EPC) and the site will be operated using Tesla's Autobidder trading platform
138 Megapacks are now operating at CleanCo’s Swanbank Battery in Queensland
The 250 MW / 500 MWh battery is built on the site of a decommissioned coal plant and will deliver clean, reliable and affordable energy to the surrounding area
444 Megapacks are powering one of Australia’s largest grid-forming batteries
The 600 MW / 1.6 GWh Melbourne Renewable Energy Hub, co-owned by @EquisEIA and SEC, is online and delivering essential grid-services
Strategically located in western Melbourne near major transmission infrastructure, the project provides system strength and grid support as renewable generation increases across Victoria
Grid-forming inverters provide critical grid stability by independently maintaining voltage and frequency
Frequency is the heartbeat of the grid - when it's disrupted blackouts can occur. As more renewables come online, grid-forming inverters are crucial for maintaining frequency and preserving grid resilience
Megapacks are currently operating in grid-forming mode across the globe
'Renewables Don't Cause Blackouts: Grid Reliability Explained'
What's the real cause of poor grid reliability and higher power costs?
Poor regulation, planning, and design.
Solar, wind, and batteries actually increase grid reliability and lower power costs, especially when paired with grid-forming inverters.
So the best approach is an all-of-the-above energy strategy, streamlined permitting, flexible grid policies, and modernized utility operations.
There are engineering challenges with higher levels of renewables, but those will be solved as a matter of course and there are already solutions available off the shelf.
Ultimately, if we want truly limitless power we need to go to outer space, which is what I'll cover in the next video of this series 🤠

Megapack is providing efficient, cost-effective energy to Texas at a time when reliable power is needed most
Eolian’s Padua project will provide 1.7GWh of energy storage to enhance grid-stability and improve grid reliability
Megapack enables more renewables to come online faster & is helping existing generation run more efficiently: "We're actually enabling [thermal plants] to last longer. Instead of retiring a plant, having to build a new one because it’s so old — you run it less, it lasts longer" Aaron Zubaty, Eolian CEO
