Data Center · 5-15 Minutes Backup Series
As the global push toward carbon peaking and carbon neutrality intensifies, low-carbon data centers are becoming a key development direction. Compared to traditional lead-acid battery systems, CLN Energy’s Energy Storage Systems (ESS) offer enhanced safety, greater system integration, and more efficient charge/discharge management. Deploying ESS in data centers offers several important benefits: 1. Stabilizing Renewable Energy – ESS can mitigate fluctuations from renewable energy sources, ensuring a stable and continuous power supply for data center operations. 2. Market Participation and Backup Power – ESS can not only serve as a backup energy source but also take part in energy market transactions, generating revenue while supporting reliable operations. 3. UPS Replacement and Grid Interaction – ESS can replace conventional Uninterruptible Power Supplies (UPS), maintaining uninterrupted power flow. Additionally, by interacting with the power grid, it boosts asset efficiency and enhances operational income. CLN Energy’s ESS solutions are well-suited for deployment in data center projects, providing power stability, reliable backup, and scalable capacity to support future growth.

Manufactured at CLN Energy's own plant at Sector 140, Noida — the plant is also the registered office, and the company is listed on the BSE SME platform under scrip 544347. Cells are lithium iron phosphate throughout.
That matters at the two moments location usually does: when something needs looking at, and when a warranty has to be honoured. Packs in service include 22,864 across BSNL's telecom network, backup at RailTel's Pondicherry command control centre, and signalling backup for Southern Railway — each on its own project page with the real configuration.
