Megapack

The Tesla Megapack is not a car — it’s a massive utility-scale battery system designed to store and deliver clean, renewable energy on a large scale. Think of it as Tesla’s powerhouse for the electric grid, capable of replacing traditional fossil-fuel “peaker” plants.

Physical Presence

Imagine a sleek, rectangular, industrial-grade white cabinet the size of a shipping container — about 23 feet long, 5 feet wide, and 8 feet high. The Tesla logo is boldly displayed on its smooth, minimalist surface. Despite its size and ruggedness, it carries the unmistakable design elegance of Tesla: clean lines, compact structure, and a futuristic vibe.

Power & Capacity

Each Megapack can store over 3.9 megawatt-hours of electricity — enough to power roughly 3,600 homes for one hour. These units can be stacked or arranged side-by-side to create entire battery farms, scaling to gigawatt levels — perfect for utilities, solar farms, or cities trying to reduce reliance on coal or gas.

Sustainability Engineered

Megapack is optimized to absorb excess solar or wind energy during peak generation and dispatch it during high-demand periods, stabilizing the grid and enabling 24/7 clean energy. It’s a central piece of Tesla’s mission to accelerate the world’s transition to sustainable energy.

Smart & Connected

Each unit comes with integrated inverter technology, thermal management, and controls, all managed via Tesla’s advanced Autobidder AI platform. It allows for real-time monitoring, automated energy trading, and seamless integration into any power grid or utility system.

Deployment Around the World

Megapack sites are already live across the globe — from California’s Moss Landing to Australia’s Hornsdale Power Reserve, where they’ve helped prevent blackouts and save millions in energy costs
