Tesla Expected to Unveil Next-Gen Megapack at Las Vegas Energy Event

Tesla is set to unveil its next-generation Megapack battery system at the 'Las Megas' event in Las Vegas, coinciding with RE+, North America's largest clean energy event. The new Megapack is expected to include innovations such as a mini Megapack with around 500 kWh capacity and a Megapack V3 featuring integrated transformers for easier grid assembly and enhanced solar power conversion, targeting applications like AI data centers and electric truck charging. Tesla continues to lead in power electronics integration, despite increasing competition from suppliers like CATL, which recently introduced a Megapack competitor with higher energy capacity. The current flagship Megapack 2XL offers 3.9 MWh of storage and advanced features for grid-scale energy projects, contributing to Tesla's rapidly growing energy division, which deployed 9.4 GWh of energy storage in Q2 2025 alone. This event highlights Tesla's push to expand its stationary energy storage market amid intensifying competition and evolving renewable energy needs. Tesla's energy storage innovations remain a critical part of its strategy to support decarbonization and enhance grid resiliency globally.
