How Tesla’s Megapack Is Quietly Powering America’s Biggest Steel Mills
Large-scale energy storage systems such as the Tesla Megapack are transforming how industries use power. Beyond balancing the grid or storing solar energy, batteries are now working behind the meter — directly inside factories.
In this video, we explore how Nucor, one of the largest steel producers in the United States, invested $51 million in a 50 MW / 200 MWh Tesla Megapack project in Kingman, Arizona. Developed by Ameresco, this is Arizona’s largest behind-the-meter battery system and one of the biggest in the U.S. Learn how Nucor uses Megapack batteries to manage its electric-arc furnaces, cut peak demand charges, and stabilize its internal power network.
This project shows how Tesla Energy is building a new business beyond cars — offering energy storage as a service and reshaping industrial energy management. Factories, data centers, and chemical plants can all benefit from the same technology.
Discover how the Tesla Megapack is becoming the core of a quiet revolution in renewable energy storage, industrial battery systems, and clean energy technology.
