   • Store historical energy data for analysis and reporting.
2. Energy Usage Analysis:
   • Analyze energy consumption patterns and identify inefficiencies.
   • Provide insights into energy usage trends over different periods (daily, weekly, monthly, etc.).
3. Energy Forecasting:
   • Predict future energy consumption based on historical data and external factors (weather, occupancy, etc.).
   • Provide energy demand forecasts to optimize energy purchasing and production.
4. Load Management:
   • Control and prioritize energy loads to reduce peak demand and avoid penalties.
   • Automatically shift non-critical loads during peak periods.
5. Demand Response:
   • Interface with external utilities or grid operators for demand response events.
   • Automatically reduce or shift load in response to demand response signals.
6. Renewable Energy Integration:
   • Manage and optimize the use of renewable energy sources (e.g., solar, wind) alongside conventional energy sources.
   • Monitor and control energy storage systems (e.g., batteries) for optimal usage.
7. Alarm and Notification System:
   • Trigger alarms for abnormal energy usage, equipment failures, or threshold breaches.
   • Send notifications to relevant personnel through various channels (email, SMS, dashboard).
8. Reporting and Visualization:
   • Generate customizable reports on energy consumption, cost, and efficiency.
   • Provide real-time and historical data visualization through dashboards and charts.
9. Energy Cost Management:
   • Track and optimize energy costs by analyzing tariff structures and energy procurement options.
   • Implement strategies to reduce overall energy expenditure.
10. User Access and Role Management:
    • Provide different levels of access and functionality based on user roles (e.g., admin, operator, analyst).
    • Ensure secure login and authentication mechanisms.

Non-Functional Requirements

1. Scalability:
   • The system should be able to handle increased data loads and additional devices or sites without performance degradation.
2. Reliability and Availability:
   • The system must have high availability, with minimal downtime, and ensure reliable data acquisition and processing.
   • Implement redundancy and failover mechanisms to maintain continuous operation.
3. Performance:
   • The system should process data and generate insights in real-time or near real-time.
   • Ensure the system can handle large volumes of data without delays.
4. Security:
   • Implement strong encryption for data transmission and storage.
   • Ensure secure access control mechanisms to prevent unauthorized access.
   • Regularly update the system to protect against vulnerabilities.
5. Usability:
   • The user interface should be intuitive and easy to navigate, with minimal training required for users.
   • Provide clear and actionable insights that are easy to interpret.
6. Interoperability:
   • The EMS should support integration with various devices, sensors, and other systems (e.g., Building Management Systems, SCADA).
   • Ensure compatibility with industry-standard protocols (e.g., Modbus, BACnet).
7. Maintainability:
   • The system should be easy to maintain, with clear documentation and support for troubleshooting.
   • Implement automated updates and patches with minimal disruption to the system.
8. Data Integrity and Accuracy:
   • Ensure that all collected data is accurate and consistent.
   • Implement checks and validation to prevent data corruption or loss.
9. Compliance:
   • The system should comply with relevant industry standards, regulations, and certifications (e.g., ISO 50001).
   • Provide audit trails and reporting features to support regulatory compliance.
10. Energy Efficiency:
    • The EMS itself should be designed to consume minimal energy and not contribute significantly to the overall energy usage of the facility.
