Delivering Consistent Uptime Across one of India’s Largest E-Commerce Networks

24×7 High demand Operations

Fulfilment centers operate non-stop - from inbound scanning to robotic sorting and dispatch. Even a few seconds of power disruption could delay thousands of orders. Ensuring continuous uptime, including during maintenance or grid variations, was mission-critical. Reliable UPS power solutions were essential to support this round-the-clock load. 

High Total Cost of Ownership (TCO)

Traditional UPS setups with overprovisioned batteries inflated both CapEx and OpEx, limiting scalability. Frequent replacements, large battery footprints, and high heat dissipation raised maintenance and energy costs — calling for a smarter, load-optimized architecture. The organisation needed an optimized TCO model that could support growth without escalating operational costs.

Efficiency and Sustainability Alignment

As operations expanded, optimizing energy performance became central. High-efficiency UPS systems played a vital role in balancing power continuity with sustainability and carbon-neutral goals. This applied not only to IT loads but also to large-scale warehouse automation power continuity needs. 

Nationwide Scalability

With operations spread across 20+ cities, the organisation required a single partner capable of delivering consistent installation, remote monitoring, and on-ground support. Ensuring uniform performance across diverse geographies demanded a fully scalable UPS infrastructure backed by a strong service network — from metros to tier-2 hubs 

Load-Aligned Power Architecture

Numeric implemented a zone-specific UPS strategy, aligning each UPS platform to actual load behaviour instead of uniform sizing across facilities. 

• Automation lines & shared infrastructure: 
  Protected using HPi 33 EVO, Keor HP, Keor MOD, and Keor T EVO  three-phase UPS systems, designed for high-availability, high-density automation environments.
• IT rooms, security systems & distributed loads: 
  Supported by Onfiniti, Digital 1000 HR V, HP Max, and Valura single-phase UPS systems—avoiding deployment of three-phase UPS where single-phase protection delivered the same operational risk outcome.

Efficiency-Led Energy Cost Control

UPS efficiency deployed across the estate included:

• Keor MOD: up to 96.8% efficiency
• Keor HP / MP class: up to 96% efficiency
• HPi 33 EVO: up to 95% efficiency

Compared to legacy UPS systems typically operating at 92–93% efficiency under partial load, Numeric’s high efficiency three phase UPS deployed reduced conversion losses by 3–4 kW per 100 kW of protected load.

These reductions translated into measurable, recurring energy cost savings—not one-time efficiency gains. 

Battery Lifecycle Cost Reduction

High-efficiency topologies (for example, three-phase UPS systems with 3-level IGBT designs and models with in-built transformers) delivered up to ~96% efficiency on select units. This generated measurable energy savings across the installed base. Combined with smaller footprints and reduced service requirements, this boosted reliability while lowering lifecycle and maintenance costs — translating into a meaningful reduction in overall TCO.

These efficiency gains supported both operational resilience and environmental goals — critical for large facilities running continuous power continuity solutions every day.

Modular Scaling

• Keor MOD (up to 96.8% efficiency) modular UPS systems were deployed using 25 kW three-phase power modules
• Capacity was added only when new fulfilment centres or automation lines became operational

This avoided: 

• Installing 30–50% unused UPS capacity upfront
• Years of inefficient under-loaded operation
• Premature battery and cooling oversizing

Capital expenditure aligned with operational growth rather than forecast assumptions, improving cash efficiency across expansion cycles. 

Controlled Risk at National Scale

• Supported by a 24×7 Customer Excellence Center
• Backed by 900+ trained service engineers nationwide
• Enabled by Virtual Remote Assistance (VRA) for rapid stabilisation

This reduced mean time to stabilisation and prevented local power events from escalating into: 

• Automation stoppages
• Dispatch backlogs
• SLA penalties

Resulted in uniform uptime behaviour across 20+ cities, independent of local grid variability.

Supporting their sustainability objectives  

Sustainability gains were engineered directly into the power layer and driven by efficiency

• High efficiency UPS deployed ensured lower electrical losses reduced energy waste at source
• Lower heat output reduced cooling energy consumption
• Modular right-sizing reduced battery material usage over the lifecycle

This supported the enterprise sustainability objectives without compromising throughput or availability.
