VoltHive is a platform that aggregates distributed energy resources, including residential battery storage systems and electric vehicle (EV) fleets with Vehicle-to-Grid (V2G) capabilities, into a cohesive Virtual Power Plant (VPP). It solves the problem of grid instability and underutilized clean energy assets by intelligently optimizing the charging and discharging of these connected batteries based on real-time grid demand, energy prices, and owner preferences. The platform provides remote monitoring, predictive analytics, and seamless integration with energy markets, allowing individual homeowners and fleet operators to earn revenue by providing grid services like peak shaving, demand response, and frequency regulation, while simultaneously enhancing grid resilience.
