An Energy Management System (EMS) is a cloud-based, cost-effective solution that measures energy usage in real-time, identifies opportunities for improvement through data analytics and modeling, and verifies savings from implemented interventions through ongoing monitoring. The EMS provides management, monitoring, analysis, and decision-making capabilities. It offers a managed service through a scalable cloud platform with no need for on-site servers or infrastructure. Key features include real-time monitoring, energy consumption analysis, energy modeling, cost-benefit analysis, and verification of energy savings.
