Data center battery storage
Advanced battery energy storage systems (BESS) are providing a strategic advantage for data centers, balancing the need for rock-solid reliability with cost savings and sustainability goals. Most UPSs have an average capacity of 50 to 300kW, providing around 20-30 minutes of backup power in case of sudden outages. It can be optimized depending on financial, sustainability, and/or resiliency requirements. Each BESS is distributed energy resource (DERs). To help industry professionals navigate these changes, ZincFive and Data Center Frontier have collaborated to produce this report, ofering insights into the current lands ape and future trends as predicted by their peers.

Why do data centers use battery energy storage systems?
The reason is that, in high-reliability grids like the Hong Kong power grid, data centers rely less on battery energy storage systems, and therefore the battery energy storage systems provide more surplus energy for energy flexibility services and obtain higher revenues.
What is battery energy storage?
In addition to DGs, battery energy storage can also serve as a component of backup power systems in data centers. According to the specifications and standards of data centers in different regions or countries, the standard battery stored energy time (SET) is usually 15 min to ensure the normal operation of the data center.
How much energy does a data center use?
On the other hand, the energy consumption of data centers is increasingly becoming a focus of attention in the power industry. Specifically, data centers consume 1.3 % of the world's electricity , highlighting the economic impacts of data center battery energy storage.
Do battery energy storage systems affect Tier II data centers?
Furthermore, battery energy storage systems have a more considerable economic impact on Tier Ⅱ data centers. Moreover, Fig. 12 reveals that as power grid reliability decreases, the revenues from providing energy flexibility services decrease at an accelerated rate of Tier Ⅳ data centers.
Which tiers of data centers are most affected by battery energy storage?
Among all tiers of data centers, the economic impact of the battery energy storage system is most significant on Tier Ⅱ data centers.
Why do data centers need a battery backup?
A portion can be reserved as a backup for data centers, while the remaining capacity, aside from the energy reserved for minimizing battery life degradation, can be utilized to provide energy flexibility services . In fact, the battery backup time is intrinsically linked to data center power reliability.
