Tesla has significantly accelerated the production of its Powerwall home battery, reaching an impressive new milestone of over 1,500 units manufactured in a single day. This marks a 50% increase from its previous peak of 1,000 units per day, a milestone achieved just three months ago at Giga Nevada.
Giga Nevada has been the central hub for Tesla’s energy storage production, supplying Powerwalls to homeowners and businesses worldwide. The facility first hit 1,000 Powerwalls per day in a 24-hour period back in November 2024.
Since then, Tesla has continued to scale up production, leading to this latest milestone of 1,500 units in a 24 hour continuous shift, according to a post from Tesla Energy on X.

The Powerwall 3, Tesla’s latest iteration of its home battery system, is designed for improved efficiency and higher energy capacity compared to its predecessors. Powerwall 3 maintains the same energy capacity at 13.5 kWh but significantly enhances power output. It delivers 11.5 kW of continuous power and can peak at 30 kW, marking a 130% increase in on-grid power capacity compared to the Powerwall 2.
To further enhance energy storage, Tesla introduced the Powerwall 3 Expansion Unit, which allows customers to scale their system. Each Expansion Unit adds 13.5 kWh of storage, but unlike the main Powerwall 3, it lacks an inverter. A single Powerwall 3 can support up to three Expansion Units, enabling a maximum storage capacity of 40.5 kWh per installation.
Tesla’s production success at Giga Nevada is part of a broader trend of the company scaling their energy storage manufacturing. While Giga Nevada continues to produce Powerwalls, Tesla moved Megapack production out of that facility in 2023 and into their new dedicated Megafactory in Lathrop, California, which celebrated the production of its 10,000th Megapack in November 2024.
Just today Tesla expanded their Megapack production capacity by opening a second Megafactory in Shaghai, China. That facility went from dirt to operating facility in less than a year, mimicking the speed at which Tesla built Giga Shanghai. With the Lathrop and Shanghai Megafactories, Tesla now has the capacity to produce 20,000 units, or roughly 80 gigawatt-hours (GWh) of energy storage per year at full production.
