Power Resilience & Energy Efficiency for Data Centres
Data centres cannot tolerate power interruptions — and with cooling consuming up to 40% of site energy, PUE targets demand more than grid supply alone can deliver. We design resilient, cost-efficient onsite power strategies built around your criticality requirements.
Resilience layered so there is never a gap
Critical IT load cannot drop for an instant. A UPS bridges the first sub-second, battery storage carries the next minutes and a standby generator sustains the site beyond — each layer overlapping the next so an outage is invisible to the load.
Data centres operate to a different standard than most commercial sites: even a brief power interruption carries severe operational and reputational consequences. That demand for absolute continuity, combined with sustained high-density loads and precision cooling, creates one of the most demanding energy briefs in any sector.
At the same time, PUE targets are tightening, grid connection costs are rising, and ESG reporting increasingly requires demonstrable carbon reduction. Sites that rely entirely on grid supply are exposed to both cost volatility and the reputational risk of a high carbon intensity.
We start from your criticality tier, cooling architecture and load profile — then design the combination of resilient backup, onsite generation and intelligent controls that meets your uptime standard while reducing the cost and carbon of every kilowatt-hour consumed.

power usage effectiveness
When uptime is non-negotiable and the load never stops
Data centre energy management sits at the intersection of absolute reliability requirements and growing efficiency pressure.
Power continuity
Even a momentary interruption can cause data loss, service outage and contractual penalty. Power protection must be seamless, not fast.
Cooling energy
Precision cooling typically accounts for 30–40% of total site energy. Even a modest PUE improvement delivers material savings at scale.
Grid cost & capacity
Large grid connections carry high reserved-capacity charges whether fully loaded or not, and securing additional capacity for expansion is slow and expensive.
Carbon & ESG
Tenants, investors and regulators are increasingly scrutinising the carbon intensity of data centre operations, including Scope 2 and Scope 3 reporting obligations.
High-density loads that cannot afford a gap
- Critical IT loads requiring continuous power availability with zero tolerance for interruption
- Precision cooling consuming 30–40% of total site energy, with PUE targets tightening
- Growing ESG pressure to reduce carbon intensity and demonstrate Scope 2 progress to tenants and investors
