Energy management
Energy Management: EMS deployment, PUE optimisation, demand response and tariff optimisation
Once supply and infrastructure are in place, we operationalise energy management: deploying an EMS/DCIM-integrated energy platform, driving down PUE through setpoint and airflow optimisation, enrolling in demand response/ancillary programmes where commercially attractive, and running continuous open-access and tariff optimisation against evolving DISCOM/exchange signals — converting the built asset into an actively managed energy portfolio.
Typical duration · 10-14 weeks for initial deployment and tuning, followed by ongoing monthly optimisation retainer
Samples generated 05 Sept 2026, 11:27 pm ISTWhat happens in this step
- 01Deploy or integrate EMS with existing DCIM/BMS, metering and PCS/chiller controllers for unified visibility
- 02Establish PUE baseline and run a 6-8 week optimisation campaign covering chiller sequencing, air management and set-point tuning
- 03Model demand response and ancillary service opportunities against DISCOM/exchange programmes and quantify risk-adjusted revenue
- 04Configure automated load-shed/curtailment logic and test through a controlled DR drill with the facility team
- 05Build a rolling open-access and tariff optimisation engine comparing group captive, third-party OA and DISCOM tariff slabs monthly
- 06Set up real-time dashboards for PUE, energy cost per rack/MW, DR performance and carbon intensity, with monthly variance reporting
- 07Hand over standard operating procedures and train facility staff on the EMS and optimisation workflows

- Facility team equipped with EMS tools, SOPs and dashboards to sustain gains independently post-engagement
Questions clients ask
Does EMS deployment require downtime or risk to critical IT load?
No. Integration is done via non-intrusive gateways and read/write permissions are staged, with all control changes tested in a sandbox or low-risk window before being applied live, keeping Tier III redundancy intact throughout.
How is demand response balanced against uptime SLAs?
We only model curtailable, non-critical loads (e.g. auxiliary cooling margin, non-IT lighting) and size DR commitments conservatively below contractual headroom, with drills conducted jointly with facility teams before any live enrolment.
Is tariff optimisation a one-time exercise or ongoing?
Tariffs, ToD structures and open-access rules change periodically; we run this as a monthly retainer function so the facility continuously captures the lowest-cost supply mix rather than reverting to a static agreement.
