Tesla has unveiled much-anticipated additions to its energy storage lineup, the Megapack 3 and Megablock – both designed to improve energy density, scalability and speed of deployment. The new products were unveiled during the RE+ renewable energy conference in Las Vegas.
Megapack 3 builds on the legacy of Tesla’s utility-scale storage products and represents a significant leap in energy density over its predecessors. It delivers approximately 5 MWh of storage capacity per unit, up from 3.9 MWh in the Megapack 2XL, which began shipping in 2022.
The most significant innovation, however, comes in the form of Megablock – a pre-engineered, medium-voltage utility-scale solution that combines four Megapack 3 units with an integrated megavolt transformer and switchgear. Each unit is designed to deliver 20 MWh AC of capacity, with a 25-year operational life and support for over 10,000 cycles. The system offers 91% round-trip efficiency at medium voltage, factoring in auxiliary loads, and is engineered to operate in extreme conditions – from -40°C to 60°C ambient temperatures.
