Key Benefits of Modular UPS Systems for Scalability

Modular UPS systems bring three standout advantages for businesses aiming to grow: flexible investment strategies, easy expansion, and improved energy efficiency. Let’s break down how these features support scalability.

Pay-as-You-Grow Capability

With modular UPS systems, businesses can start with the capacity they need today and add modules as their power demands grow. This eliminates the need for upfront overinvestment and helps keep both initial and long-term ownership costs in check. Unlike traditional UPS systems, which require companies to predict their power needs years in advance - often leading to over-provisioning or under-preparing - modular systems adapt to changing requirements.

Additionally, advanced lithium-ion batteries enhance this flexibility. They offer two to three times the service life of VRLA batteries, boast up to 10 times the cycle life, and take up only a third of the space.

Better Energy Efficiency

Modular UPS systems don’t just grow with your business - they also help you save energy. Compared to centralized systems, modular setups are far more efficient. One key advantage is their ability to deactivate unused modules during periods of low power demand, ensuring the system operates at peak efficiency .

ENERGY STAR-certified UPS models can reduce energy losses by 30–55%. Modern UPS systems typically operate with 92% to 95% efficiency, a significant improvement over older models that often fall below 90%. For large-scale installations, these efficiency gains translate into considerable cost savings.

Take Exelon’s Joliet, Illinois Data Center as an example. By reconfiguring its UPS modules, the facility improved efficiency to over 90%, reduced its PUE from 1.96 to 1.146, and maintained its energy use despite a fivefold increase in computing capacity.

"Replacing the old UPS systems was probably our biggest challenge on the path towards a more efficient facility, but it also provided one of the biggest payoffs in terms of efficiency." - Dom Lovino, Exelon Corp's Manager of Data Center Operations

The savings can be substantial. A 1,000 kVA UPS in a large data center could save approximately $18,000 annually by switching to an ENERGY STAR-certified system. For a 15,000-square-foot data center, improving efficiency from 90% to 95% could cut annual energy use by 768,421 kWh, translating to about $90,000 in savings at $0.12 per kWh. Modular systems achieve these results by scaling capacity in line with IT load growth, keeping the system’s load factor high. This not only reduces energy costs but also lowers carbon emissions and the overall cost of ownership.

How to Implement a Modular UPS System

Implementing a modular UPS system effectively involves a structured approach. It includes three main steps: understanding your power requirements, selecting the appropriate equipment, and planning for maintenance and future growth.

Assessing Power Requirements

Start with a power audit. This process helps you pinpoint critical equipment, evaluate power quality, and calculate both current and future needs.
