Jun 3, 2025 · The companies will bring to market a first-of-its-kind BESS system that can act as a reliable, high-performance alternative to conventional UPS systems outside the data center
Jun 11, 2025 · The Project FlexGen and Rosendin are tinkering on a utility-scale battery solution to be situated outside a data center building, as part of medium-voltage (1,000V to 35,000V)
This capability is crucial for energy-intensive environments like data centers, where the need for sustainable and reliable power grows. Using advanced energy management systems to improve efficiency, BESS helps mitigate energy losses from voltage mismatches between power grids and devices.
Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation. BESS fire safety standards, such as NFPA 855, outline minimum requirements for backup power for fire safety systems.
BESS acts as chameleon that can adapt to varying power sources and customer and grid needs, from backup power to peak shaving and frequency regulation. When it comes to ensuring reliable data center power, battery storge plays key roles in reducing demand, enhancing power quality, and delivering uninterruptible supply.
Traditionally, data centers rely on diesel generators or Uninterruptible Power Supply (UPS) systems to provide backup power, but these solutions come with their own limitations—fuel costs, maintenance, and delays in activation. BESS provides an instantaneous response, stepping in seamlessly when there’s a disruption in the main power supply.
If a BESS product cannot meet these backup power requirements as mandated by the code or the Authority Having Jurisdiction (AHJ), an external backup power source needs to be provided. Options for backup power include local distribution network feeders (if available with sufficient kVA rating) or backup generators.
Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not need an external supply.
