Unlike conventional battery energy storage systems (BESS), Volt Harbor uses Medium Access Control (MAC)-BESS™. It is modeled on computer networking architecture, utilizing software to enable battery modules from different manufacturers (first and retired EV batteries) and chemistries to share and coordinate power flow through the system in real time. A unique fit for solving the challenges created by AI data centers. Training runs ramp racks of chips up and down in bursts — sometimes within milliseconds — and those swings can stress and damage substations and other grid equipment. Morgan Stanley recently called battery storage "a system-level necessity" for absorbing that volatility.
