Ecosuite is distributed energy resource management software designed to deploy and operate DERs at scale using open-source foundations and AI technology. The platform offers asset management tools powered by edge-compute technology for grid operations, enabling monitoring, maintenance, and control of assets via mobile and web interfaces. Ecosuite includes Foresight, an AI-enabled feature for predictive maintenance, energy forecasting, and project underwriting. The software integrates a Department of Energy-funded data science toolkit for managing diverse energy resources. Modules streamline project milestones, cashflow forecasting, partner engagement, and underwriting processes. Finance and underwriting tools support investment decisions, while grid services function as an energy network operating system.
