Energy Management System (EMS) - Complete Implementation Roadmap Document
EXECUTIVE SUMMARY
This document outlines a 12-month phased implementation roadmap for a production-grade Energy Management System (EMS). Starting from existing BMS data integration, we systematically build from safety foundations to full commercial deployment with grid services and machine learning optimization.
Key Principles:
