Enterprise EMS Energy Management System
From Sensing to Reporting, in One System
An enterprise platform integrating SCADA visualization, coordinated dispatch, automatic control, COP efficiency optimization and government reporting. Built entirely on an open-source stack — no license fees, no vendor lock-in, fully offline deployment supported.
Energy Management Should Be More Than Meter Reading
Regulations tighten every year, electricity and carbon costs keep rising, yet equipment is scattered and hard to monitor centrally. What enterprises really need is a platform that links real-time monitoring → efficiency analysis → automatic control → one-click reporting into a single chain, not isolated meters plus a pile of spreadsheets.
See It
SCADA single-line diagrams show chillers, pumps and cooling towers' operating status and consumption in real time — the whole plant at a glance.
Save It
Instantaneous and system COP and kW/RT are calculated live, low-efficiency equipment is flagged automatically, and energy-saving control strategies follow.
Report It
Energy audit, savings-rate and REO reporting templates are built in, with digital signatures and an audit chain — keeping pace with regulatory deadlines.
Seven Core Function Modules
A complete closed loop from data acquisition to government reporting — every link auditable, traceable and extensible.
Visualization / SCADA
Single-line diagrams and writable point control (switching, setpoints); commands are released only after RBAC authorization and two-person review.
Coordinated Control / DERMS
Resource portfolios, constraint panels, actionable dispatch recommendations and scenario simulation to orchestrate energy resources across multiple sites.
Automatic Control
PID, logic and schedule governance with version rollback and fail-safe degradation on connection loss, keeping the site safe under any condition.
COP Efficiency Calculation
Instantaneous COP, kW/RT and system COP computed in real time and fed directly into energy-saving optimization decisions.
Smart Alarms
First-out detection, acknowledgment, suppression and deadband/delay debouncing, aligned with the ISA-18.2 alarm management standard.
Reporting Gateway
Energy audit, savings, REO and monthly reports generated in one place, with X.509 digital signatures and a full audit chain.
Unified MQTT Data Acquisition
Devices and gateways publish directly to EMQX over MQTT 5.0, following a one-entity-one-topic, flat-payload standard; devices self-describe on connection and points are created automatically. Legacy non-MQTT equipment connects through an on-site gateway — no plant-wide replacement needed.
Find Savings with Data
The system computes chiller efficiency metrics in real time, quantifying every unit and every refrigeration group — so savings are evidence-based and verifiable, not tuned by feel.
Sensing → Data → Analysis → Control → Savings → Verification
An end-to-end energy management loop, every stage standardized and auditable.
Fully Open-Source, Enterprise-Grade, Offline-Capable
Built on mature open-source components with no license fees or vendor lock-in, supporting fully air-gapped offline deployment.
Mapped to Taiwan Energy Regulations and International Standards
Implemented per the Large-Scale EMS Design Report, covering major regulatory filings plus international standards for cybersecurity and energy management.
| Regulation / Standard | System Capability |
|---|---|
| Energy Administration Act | Monitoring / history / reports / master data / energy managers / sub-metering / audit trail |
| FY114–117 Energy-Saving Rules | Three-tier HQ → site → meter-ID structure with cross-site savings KPIs |
| Energy Use Data Reporting | Annual / monthly / multi-type reports with built-in templates and validation |
| Renewable Energy Obligation Rules | Implementation plans / operating data / corrections |
| Electronic Signatures Act | X.509 signing service / certificate management / digests / timestamps |
| Cyber Security Management Act | ISMS / zoning and segmentation / audit logs to SIEM |
| International Standards | ISO 50001 / 50006 · IEC 61850 / 62351 / 62443 · OPC UA · ISA-18.2 / ISA-101 |
Benefits
Low Adoption Cost
Fully open-source stack with no software license fees; one-click Docker deployment cuts integration hours too.
Security & Audit
RBAC role separation, two-person review and a complete audit chain, meeting Cyber Security Management Act requirements.
Scalable Architecture
Standardized MQTT onboarding — add devices or sites without changing the architecture, and scale horizontally as the business grows.
Works Offline
Air-gapped offline package deployment for isolated OT networks — no need to change security policy just to go to the cloud.
Field-Ready
Self-describing devices, automatic point creation and direct SCADA control, matching the way field engineers already work.
Rollback-Safe
Semantic versioning plus per-service hotfixes — roll back in seconds when something goes wrong, so operations can breathe easy.
