Tech OVN Energy Management System (EMS) — Class 0.5S submetering with cloud dashboard

A Real Energy Management System — Without the Vendor Lock-In

The Tech OVN Energy Management System (EMS) gives industrial, commercial, and multi-site portfolio operators continuous visibility into electricity consumption — down to individual feeders, machines, tenants, or floors. Real-time dashboards, multi-site benchmarking, configurable alerts, and ISO 50001-ready reports run on hardware we design and manufacture in-house.

Deployed across factories, data centres, hospitals, hotels, malls, and commercial buildings — by facility managers, energy heads, ESG teams, and BEE-empanelled auditors — to reduce energy spend, support ISO 50001 EnMS programmes, and underpin tenant billing. Open Modbus / BACnet / MQTT / REST integration means our meters drop into existing BMS, SCADA, or IoT stacks without forcing a rip-and-replace.

What the EMS Does

Six capabilities that separate a real Energy Management System from an analytics dashboard sitting on top of monthly bills.

Real-Time Power Visibility

Live power, energy, voltage, current, and power factor across every monitored circuit, refreshed every few seconds — not 15-minute snapshots.

Multi-Site Cloud Dashboard

Single-pane view across factories, plants, branch offices, or campuses. Drill from portfolio level down to individual feeder or asset.

Class 0.5S Accuracy

Utility-grade revenue accuracy (IEC 62053-22) on every meter — so the numbers behind your tariff decisions, M&V reports, and tenant bills hold up under audit.

Submetering by Load, Floor, or Tenant

Allocate consumption to production lines, departments, tenants, or building zones. Foundation for chargeback, ISO 50001, and energy-efficiency ROI tracking.

Open Communication

RS485 Modbus, BACnet, MQTT, OCPP, REST API. Integrates with existing BMS / SCADA / IoT platforms — no rip-and-replace required.

Alerts & Anomaly Detection

Configurable thresholds for demand, consumption, power factor, and voltage events. Email, SMS, and webhook notifications when anomalies occur.

Where It's Deployed

The EMS is built for portfolios — single sites and 200-site networks alike, across multiple industries and countries.

Factories & Manufacturing Plants

Per-shift, per-line, per-machine energy attribution. ISO 50001 compliance support. Identify energy waste in compressed air, HVAC, motors, and process loads.

Commercial Buildings & Offices

Floor-by-floor and tenant-by-tenant energy visibility for chargeback, lease audits, and operational efficiency reporting.

Data Centres

PUE measurement, IT load vs cooling load split, redundancy validation, and rack-level submetering for colocation billing.

Hotels, Malls & Hospitality

Common-area vs guest-area split, kitchen and laundry submetering, F&B chargeback, and energy KPIs per occupied room.

Hospitals & Healthcare

Critical-load monitoring, OT/ICU power-quality visibility, redundancy validation across DG and grid sources, and submetering for departments.

Multi-Site Retail & Branch Networks

Standardised energy management across hundreds of stores or branches with central dashboard, alerts, and benchmarking.

Industry-Specific EMS Playbooks

How a real Energy Management System is configured, deployed and used in four industries we know best:

EMS for Factories

BEE PAT, ISO 50001, per-line SEC tracking, MES/SAP integration.

EMS for Data Centres

Real-time PUE, rack-level colocation billing, 2N redundancy validation, DCIM integration.

EMS for Hospitals

OT / ICU power-quality monitoring, NABH-aligned reporting, departmental cost allocation.

EMS for Commercial Buildings

Tenant chargeback billing, BMS integration, LEED / IGBC / GRIHA / BRSR reporting.

Why Tech OVN

What separates a hardware-grounded Energy Management System from a cloud dashboard with someone else's meters.

Built on Hardware We Manufacture

Most EMS vendors are software companies stitching third-party meters together. We design and manufacture the meters, write the firmware, and operate the cloud — single accountability across the stack.

Class 0.5S, Not Class 1.0

Our standard meter is Class 0.5S — the same accuracy class utilities use for revenue billing. Most low-cost EMS systems compromise on Class 1.0 or 2.0 hardware that drifts under real-world load.

Open by Default

Modbus, BACnet, MQTT, REST. Your data is yours. We don't lock you into proprietary protocols or charge per integration.

Built for Multi-Site, Multi-Country

The platform was designed for portfolios — multiple sites across multiple countries, multi-currency tariffs, multi-language dashboards. Deployed in 10+ countries from a single Delhi NCR manufacturing base.

Hardware Behind the EMS

The EMS runs on the Titan family of meters and the Tech OVN Energy Intelligence Platform. Pick the meter that matches each circuit — energy, thermal, power quality, condition monitoring — all feed the same dashboard.

Frequently Asked Questions

Common questions about what an EMS is, how it compares to BMS / SCADA, ISO 50001 compliance, integration, accuracy, ROI, and international supply.

An Energy Management System (EMS) is a combination of hardware and software that continuously measures, monitors and controls electricity consumption across a facility — at the incoming feeder, at major loads, and at sub-loads — and presents the data on a real-time dashboard with alerts, reports, and historical trends. The Tech OVN EMS combines our own Class 0.5S 3-phase smart meters with a multi-site cloud dashboard, mobile app, and open APIs. It supports ISO 50001 measurement and verification out of the box.
A BMS (Building Management System) controls HVAC, lighting and access at the building level. SCADA monitors and controls industrial process equipment. An EMS focuses specifically on the measurement, analysis and optimisation of energy consumption — usually overlaid across BMS and SCADA. The Tech OVN EMS is open by default (Modbus, BACnet, MQTT, REST) so it can feed data into an existing BMS / SCADA, or consume data from them. See our full EMS vs BMS vs SCADA comparison guide at /energy-management-system/vs-bms-scada.
Yes. The platform provides the sub-metered consumption, baseline establishment, EnPI (Energy Performance Indicator) tracking, M&V (Measurement & Verification) data, and audit-ready reports needed for an ISO 50001 EnMS programme. We sell the same hardware to most BEE-empanelled energy auditors in India for exactly this purpose.
Manual reading gives you a monthly snapshot — usually too late to act on. A real-time EMS updates every few seconds, so you can see demand spikes as they happen, attribute consumption to specific shifts or events, prevent maximum-demand penalties, and identify energy waste while it's still happening — not in next month's bill.
Yes. We support Modbus RTU / TCP, BACnet, MQTT, and REST APIs — so existing meters, BMS, and SCADA platforms can feed into the Tech OVN cloud, and our meters can feed into your existing BMS or SCADA. Greenfield and retrofit deployments are both supported.
Yes. The platform is designed for portfolios — we have customers with deployments across factories, branch offices, and retail networks spanning multiple states and countries. Role-based access, site grouping, benchmarking, and consolidated reporting are built in.
Energy meters comply with IEC 62053-22 Class 0.5S, IS 16444, and BIS licensing. Power quality meters comply with IEC 61000-4-30 Class A. Cloud and security follow ISO 27001 best practices.
Yes. We ship from Delhi NCR to the Middle East, Europe, Southeast Asia, and Africa. Multi-language dashboards, multi-currency tariff support, and regional time zones are standard. Country-specific certifications can be arranged for tender-driven deployments.
Industry studies (US DOE, EU Energy Efficiency Directive, BEE India) consistently show 5–15% energy cost reduction within the first 12 months of deploying a real-time EMS — driven by waste identification, peak-demand management, and operational behaviour change. Payback typically falls between 12 and 24 months for industrial deployments.
