Giga-Scale Projects

We took everything we know about battery technology to enable the world's largest energy projects. A 1 Gigawatt hour (GWh) project provides record energy capacity—enough to power every home in San Francisco for 6 hours.

All-in-One System

Every Megapack arrives pre-assembled and pre-tested in one enclosure from our Gigafactory—including battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls. No assembly is required, all you need to do is connect Megapack’s AC output to your site wiring.

Fastest Installation

At the site level, Megapack requires 40% less space and 10x fewer parts than current systems on the market. As a result, this high-density, modular system can be installed 10x faster than current systems.

Applications

  • Renewable Smoothing
    Smooth out the intermittency of renewables by storing and dispatching when needed
  • T&D Investment Deferral
    Postpone costly grid infrastructure upgrades by supplying power at a distributed location to defer the need to upgrade aging infrastructure
  • Voltage Support
    Inject and absorb reactive power to maintain local voltage levels on the grid
  • Capacity Support
    Discharge at times of peak capacity to reduce demands on distribution and transmission infrastructure
  • Microgrid
    Build a localized grid that can disconnect from the main power grid
  • Market Participation
    Provide service to the grid in response to signals sent by system operators
  • Frequency Regulation
    Maintain grid stability by rapidly changing charge or discharge power in response to changes in grid frequency
  • Megapack is designed for utilities and large-scale commercial customers. Our team of experts will work with you to identify custom site needs, and design a solution to maximize project values across multiple applications.
