EnerSys has introduced the DataSafe Noir lithium-based energy storage system for data center power, targeting performance under “real-world and dynamic load conditions,” including AI-driven demand profiles. EnerSys says the system is available immediately.
DataSafe Noir is positioned as an integrated platform intended to deliver “predictable, controlled system performance under load” in high-density environments. EnerSys is emphasizing system behavior under stress, rather than selecting storage based only on chemistry, runtime, and cost—an argument aimed at operators dealing with highly variable, real-time power demand.
EnerSys claims that, compared to “publicly available specifications for leading lithium systems,” DataSafe Noir delivers more than 2x output power and over 1.7x greater energy and capacity. The company ties those claimed deltas to more compact deployments and improved utilization of data center floor space, though it doesn’t provide absolute power, energy, or footprint numbers in the material.
From an engineering perspective, the focus on controlled behavior under fast-changing loads is a practical theme for modern facilities, where load transients and rapid ramp events can stress the entire power train—not just the battery modules. But without published power and energy figures, most teams will still need to treat the “2x” and “1.7x” comparisons as directional until they can map the system to a specific UPS or BESS architecture and validate it against site requirements.
EnerSys is also leaning on lifecycle support as part of the offering: DataSafe Noir systems are backed by the company’s global installation, commissioning, and service network, which EnerSys describes as providing “a single point of accountability across the system lifecycle.” The company says the platform is designed for repeatable deployments across hyperscale and colocation environments.
“The real issue is how the system behaves under stress, particularly in high-density environments,” said John Gagge, vice president of business development, energy systems at EnerSys. “The DataSafe Noir system is designed to give operators control over that—not just improve performance on paper.”
