Power, storage and flexibility engineered as one operating system
DCSix integrates on-site generation, off-grid and hybrid ESS, demand response and grid-flexibility services so data centre operators can keep IT load available, control energy cost, and participate in the market without adding operational risk.
Systems integration
Electrical, BMS, metering and control
Off-grid & hybrid ESS
Island, backup and peak-shave modes
Demand response
Fast, auditable load and storage response
Grid flexibility
Tariff, constraint and market-ready control
Capabilities
We work from the operations desk, not a slide deck. The question is whether cooling, UPS, generators, batteries and the grid connection can be coordinated under one control strategy that facilities and energy teams can trust.
Systems integration
We connect plant that was never designed as a single system: inverters, battery EMS, generators, ATS/MTS, meters, BMS, SCADA and cloud telemetry. Typical stacks include Modbus, BACnet, MQTT, REST APIs and time-series dashboards.
Off-grid & hybrid ESS
We design and commission hybrid and islanded energy storage so critical load can ride through grid events, constrained connections, or planned island operation. Control logic covers SOC limits, breaker sequencing, load ramp and generator coordination.
Demand response and Grid flexibility
We turn measured load and storage into controllable flexibility: peak shaving, tariff shifting, constraint management and demand-response participation, with clear operator override and evidence for operations and commercial teams.
Why DCSix?
DCSix is an Irish energy-systems company. We combine electrical contracting, industrial networking, software and live energy data. That mix is what data centre operations actually need when ESS, cooling and grid services have to work together on a live site.
What operations needs
One picture of power, cooling and storage
Safe transfer between grid, generator and battery
Use of ESS beyond backup
Audit trail and commercial evidence
Remote, multi-site visibility
What DCSix delivers
Sub-metering, live dashboards and plant-level KPIs across electricity, generation and ESS
Safe transfer between grid, generator and battery
Use of ESS beyond backup
Revenue-grade metering approaches, event logs, and reports operations and energy teams can stand over
Secure telemetry, 4G/VPN paths, alerting and operator-ready visualisation
Engagement
How an engagement typically starts:
-
Operations briefing — Site electrical topology, IT criticality, cooling plant, existing EMS/BMS, grid connection constraints and commercial objectives.
-
Integration assessment — What can be controlled today, what must be added, and where ESS, DR and island modes conflict with availability.
-
Scoped delivery — Controls, metering, dashboards and commissioning on an agreed subset of plant, then scale. Detail is shared under NDA on request.
-

We do not publish client-specific architecture or performance data on this page. If you are assessing DCSix for data centre systems integration, off-grid ESS, demand response or grid flexibility, contact us and we will arrange a technical discussion with the people who deliver the work.
