The Tesla Lathrop Megafactory reached a new milestone by producing its 15,000th Megapack battery, as announced by the official Tesla Megapack account.
The Megapack battery is essential for Tesla Energy's grid-scale projects, providing 3.9 MWh of energy and 1.9 MW of power with scalability for large energy storage initiatives.
Tesla commemorated the achievement with a photo of the Lathrop Megafactory team holding balloons spelling out '15,000' alongside the newly produced Megapack battery.
The Lathrop Megafactory is Tesla's primary facility for Megapack production, standing as the largest utility-scale battery factory in North America, capable of producing 10,000 Megapack batteries annually.
In addition to its Lathrop Megafactory, Tesla launched the Shanghai Megafactory to meet energy storage demands, with both facilities collectively targeting 40 GWh of annual energy storage production.
Tesla noted in its Q1 2025 Update Letter that the Shanghai Megafactory made significant progress by manufacturing over 100 Megapack batteries in the first quarter alone.
Elon Musk highlighted the value of the Megapack in the energy sector during the first quarter earnings call, emphasizing its ability to enhance total energy output for utility companies significantly.
