MeterMaestro is an open-architecture, digital-twin-based orchestrator for residential behind-the-meter energy storage integration. Led by researchers at the University of Louisiana at Lafayette, our platform unifies multi-vendor solar, battery, EV, and smart-load assets behind a single consumer interface delivering both economic dispatch and autonomous resilience during outages. Backed by peer-reviewed research, the Cleco Alternative Energy Center microgrid testbed, and an active industry integration partner, we are building the missing interoperability layer for Gulf Coast homes.
