Tech OVN

Energy Management System for Data Centres & Colocation Facilities

An Energy Management System (EMS) built for data centres — continuous PUE measurement, rack-level submetering for colocation billing, 2N redundancy validation, and DCIM integration. Class 0.5S accuracy, ISO 27001-aligned cloud, deployed across Indian and Southeast Asian colocation operators.

Tech OVN Energy Management System for data centres — real-time PUE and rack-level submetering

PUE Is the KPI. Your Meters Decide if You Can Trust It.

Power Usage Effectiveness is the single number that defines data centre efficiency. But a PUE reported once a month from Class 1.0 meters at the incomer and an estimated IT load isn't a KPI — it's a story. A real Energy Management System gives you Class 0.5S measurement at the incomer, the UPS output, every mechanical feeder, and every rack — continuously. That's what makes PUE actionable, billable, and defensible in front of a sustainability auditor.

The Tech OVN EMS combines Class 0.5S Titan meters with a multi-tenant cloud platform built for colocation operators, hyperscale tenants, and enterprise data centre teams. Real-time PUE, per-rack billing, redundancy validation, and clean integration with DCIM — without forcing a rip-and-replace of the meters or software you already have.

What a Data Centre EMS Does

Six capabilities that move PUE from a monthly story to a real-time KPI.

Real-Time PUE Measurement

Continuous Power Usage Effectiveness calculation — total facility power vs IT load — refreshed every few seconds, not as a monthly average. Spot HVAC drift, free-cooling failures, or UPS inefficiency the moment they happen.

Rack-Level Submetering for Colocation Billing

Class 0.5S submetering at the rack, the PDU, or the customer cage — accurate enough for revenue billing. Auto-generated invoices per customer, per rack, per kWh actually used, with audit-ready supporting data.

Redundancy & Source Validation

Track grid, DG, UPS-A and UPS-B feeds independently. Validate that 2N redundancy is actually 2N, detect transfer-switch anomalies, and catch a degraded UPS battery string before the next outage exposes it.

IT vs Cooling vs Lighting Split

Sub-meter chillers, CRACs, lighting, and IT loads separately. The split tells you exactly where your PUE gap is — and which mechanical or electrical project will move it the most.

DCIM / BMS Integration

Modbus, BACnet, SNMP, MQTT, and REST — feed Titan data into Schneider EcoStruxure IT, Vertiv Trellis, Sunbird, Nlyte, or your in-house DCIM. We don't compete with DCIM; we make it accurate.

ESG & Sustainability Reporting

Scope 2 carbon emissions auto-calculated per customer, per rack, per region. Renewable mix percentages for green-tariff customers. Ready for CDP, GRESB, and SBTi disclosures.

Frequently Asked Questions

PUE measurement, colocation billing, redundancy validation, DCIM integration — common questions from data centre operations and sustainability teams.

Yes. Titan meters on the utility incomer, the UPS output (IT load), and the mechanical / lighting feeders give the EMS everything it needs to compute Power Usage Effectiveness continuously — typically refreshed every 1–5 seconds. The platform stores historical PUE for trend analysis and benchmarks against ASHRAE / Uptime Institute targets.
Yes. Class 0.5S Titan meters at the rack or PDU level give revenue-grade accuracy for per-customer billing. The platform supports multi-tenant access (each colo customer sees only their racks), automated billing exports to your finance system, and audit logs for dispute resolution.
By metering both A and B feeds independently (and DG / grid / UPS sources separately), the EMS can verify that load is balanced across redundant paths, detect transfer-switch operations, and alert when one path is carrying significantly more load than the other — a common early sign of a degraded ATS or a failed-over UPS that didn't fail back.
Yes. Titan supports SNMP, Modbus TCP, BACnet/IP, MQTT, and REST — the protocols every major DCIM platform speaks. We have customers feeding Titan data into Schneider EcoStruxure IT, Vertiv Environet/Trellis, Sunbird dcTrack, and Nlyte. We don't replace DCIM; we replace the unreliable third-party meters DCIM was originally fed with.
Titan meters comply with IEC 62053-22 Class 0.5S for energy accuracy and IEC 61000-4-30 Class A for power quality (Titan PQ variant). The platform follows ISO 27001 information security best practices. For data centre tender-driven deployments, country-specific certifications can be arranged.
