Data centers require continuous access to reliable electricity. Servers, cooling equipment, networking infrastructure, security systems, and monitoring equipment must remain operational even when the utility supply experiences disturbances. As computing demand grows, data center operators are also looking for ways to improve energy efficiency and manage increasingly complex power requirements. An Energy Storage System can complement traditional backup infrastructure while supporting power quality, renewable integration, and more flexible energy management.

Why Data Centers Need Advanced Energy Storage

A data center cannot treat electricity storage in the same way as a conventional commercial facility. Even a brief power interruption can affect critical computing operations, while longer outages can create substantial operational and financial consequences.

Traditional uninterruptible power supply systems remain essential for maintaining continuity during transitions and disturbances. However, battery-based storage can serve additional purposes when properly integrated into the facility’s electrical architecture.

An Energy Storage System can support backup power, peak-demand management, renewable-energy integration, and other energy-management functions. The appropriate configuration depends on the facility’s load profile, required backup duration, power architecture, and operational priorities.

Lithium-Ion Battery Technology for Modern Facilities

Li-ion batteries are widely used in stationary energy storage because of their energy density, efficiency, and cycling capability. For data centers, battery selection should consider discharge performance, thermal management, cycle life, safety, monitoring, maintenance, and system compatibility.

LFP batteries are also gaining importance, accounting for around 90% of battery storage deployments in 2025, according to the International Energy Agency.

High-Power Storage for Backup Applications

Data center backup systems may need to deliver substantial power within a short period. This makes power capability a key selection criterion alongside total energy capacity.

A system with high energy capacity is not automatically suitable for a high-power application. Operators should determine the maximum required load, expected discharge duration, transition requirements, and the critical equipment that must remain energized.

Great Power’s technology portfolio includes high-power UPS battery technology and energy-storage solutions designed for UPS backup applications. Its official information identifies UPS backup as one of the applications covered by its energy-storage business.

Thermal Management and Operating Conditions

Data centers generate significant heat, making thermal management essential for battery installations. Battery performance and safety depend on temperature, charge and discharge rates, and operating conditions.

An Energy Storage System should include suitable cooling, temperature monitoring, and maintenance plans. Liquid cooling is increasingly used in larger systems, although the best approach depends on system scale, battery design, and installation conditions.

Safety Should Be Evaluated at System Level

Battery safety is particularly important in data center environments because storage equipment may be installed near mission-critical infrastructure. Safety planning should cover battery cells, battery management systems, electrical protection, thermal controls, fire detection, and emergency procedures.

Data center operators should review applicable testing and certification documentation when comparing suppliers. Great Power states that its energy-storage batteries have certifications including IEC 62619, UL 1973, and UL 9540A, alongside other quality and compliance qualifications.

Certification does not replace site-specific engineering. Operators should still work with qualified professionals to determine appropriate separation, ventilation, detection, suppression, and emergency-response measures.

Storage Can Reduce Data Center Energy Costs

Backup capability is only one potential application. Data centers can also use storage to manage electricity demand and improve energy efficiency.

Where utility tariffs include demand charges, a battery can discharge during selected periods to reduce grid demand. Energy storage can also shift electricity consumption between different tariff periods when time-of-use pricing is available.

For facilities with onsite solar generation, storage can capture surplus electricity and make it available later. This can improve renewable-energy utilization while reducing reliance on grid electricity during selected operating periods.

Evaluate the Supplier’s Manufacturing Capabilities

For mission-critical facilities, supplier reliability matters as much as technical specifications. Data center operators should assess manufacturing quality, supply capacity, certifications, technical support, monitoring capabilities, warranty conditions, and lifecycle service.

The company was founded in 2001 and introduced its first-generation energy-storage battery in 2011. Its current energy-storage portfolio covers utility-scale, C&I, residential, UPS backup, and portable applications, with operations extending across more than 50 countries and regions.

This broad application experience gives the company exposure to different storage requirements. For data center operators, such experience can be relevant when evaluating whether a battery supplier has the technical and manufacturing resources required for demanding infrastructure projects.

How to Choose the Best Option

There is no single storage configuration that is ideal for every data center. Operators should begin with a detailed assessment of critical loads, backup duration, power requirements, electrical architecture, environmental conditions, and future expansion.

A Great Power battery can be considered as part of this evaluation, particularly where operators require storage technologies supporting UPS backup and broader energy-management applications. The company’s portfolio includes both battery-level and system-level solutions, allowing different architectures to be considered according to project requirements.

The final decision should balance safety, power capability, usable energy, efficiency, lifecycle performance, space requirements, and total cost of ownership rather than focusing on capacity alone.

Building More Resilient Data Center Power Infrastructure

The role of storage in data centers is expanding beyond backup, supporting resilience, energy management, and renewable integration. The company combines battery manufacturing experience with energy-storage solutions for infrastructure applications, including UPS backup.

For data center operators, selecting the right Energy Storage System requires balancing reliability with long-term energy goals. Proper system design, battery technology, and supplier selection can create more resilient and adaptable power infrastructure.
