Load smoothing
- Absorbs 0.1–55 Hz GPU-driven DC load swings so the grid sees a smoother, more predictable power profile
- Meets ISO requirements (<1% cyclic power at grid interface)
Data Center Power
Grid-ready power for AI data centers
Launched: ZettaWatt™ Power Platform
ZettaWatt™Power Platform
Power for AI.Stability for the grid.Deployable now.
The challenge
Power availability and interconnection timelines now determine how quickly AI data centers can come online.
Utilities must evaluate not only whether the grid can supply these massive new loads, but also whether the facility can remain connected through grid disturbances and prevent rapid AI load fluctuations from affecting grid stability.
Until these requirements are addressed, energization is delayed, and valuable compute capacity sits idle.
ZettaWatt™ Power Platform
Accelerating the path from grid interconnection to operational AI compute.
A modular grid-to-800 VDC architecture built from repeatable up to 5 MW-class power platforms that scale across gigawatt-scale AI data-center campuses. ZettaWatt™ reduces power-integration risk, brings AI capacity online faster and helps developers meet utility performance requirements.
Meets grid requirements and integrates critical capabilities:
- Cyclic AI load smoothing to less than 1%
- Low-voltage ride-through
- Demand response
- Integrated UPS backup power
One modular platform. Multiple power-system functions.
The ZettaWatt™ Power Platform is designed on DIMAAG's ZettaWatt™ power architecture. Each platform serves an electrical block and can be deployed in parallel as campus capacity grows.
Efficient, scalable and ready for extremely dynamic AI workloads
ZettaWatt™, by DIMAAG, is a grid-aware complete power architecture for next-generation AI data centers. ZettaWatt™ enables resilient AI infrastructure deployment through unified power stabilization, energy storage and intelligent control for both 800 VDC and 50 VDC systems. The 800 VDC architecture is designed to bring battery-backed power closer to compute loads, improving response time, power density and grid isolation.
AI training workloads
Isolating compute energy from the grid, AI training workloads can create fast, repeated transitions between low and high power states. DIMAAG's battery system absorbs DC-side fluctuations while delivering peak power directly to compute, helping keep AC input smoother and more predictable.
Grid compliant
Built for the latest utility rules such as ERCOT's NOGRR802, which went into effect on Aug 1, 2026. Utilities and ISOs are moving toward stricter requirements for large, fast-changing loads, including limits on ramp rates, load oscillations and low-voltage ride-through. DIMAAG's architecture is designed to help data centers prepare for these and emerging interconnection requirements.
Deployment ready and independently validated
Validated end-to-end. The architecture has been independently simulated by Electric Power Engineers, LLC, then built and demonstrated under AI training workload conditions. The architecture is designed to scale from rack-level deployments to 100 MW data-center infrastructures.
Designed for the next generation of AI data centers.
AI-assisted control system
Intelligent, unified control layer coordinating power distribution and subsystems in real time.
Unified energy storage
Single battery system for UPS, BBU and load smoothing, no capacitors required
High-power actively-cooled battery
LFP and LTO options with extended battery life, no thermal runaway, optimized for rack or container deployments
Grid-aware energy management
Software that reads grid signals, predicts demand, and responds automatically
ZettaWatt™ capabilities
Instantaneous backup power
- Provides instantaneous backup response for critical compute loads
- 4-minutes UPS support with zero DC-side switching, enabling seamless generator startup and ramp-up, compatible with third-party systems
Low-voltage ride-through
- Remains grid connected
- Meets ISO requirements
Demand response
- Responds rapidly to utility and ISO demand response events without disrupting compute operations
Deployment and operational advantages
Faster path to power
Provides a defined power-control architecture that can be modeled and incorporated into utility and interconnection discussions early in the project.
Reduced deployment risk
Uses a modular 5 MW-class building block to reduce custom engineering and create a clearer path from design through commissioning.
Grid compliant
Shapes a volatile AI load into a steadier, controllable grid-facing profile and supports ride-through behavior as part of the complete site design.
Reduced electrical complexity
Combines functions commonly assigned to separate UPS, transient storage, backup and demand-response systems.
Efficient 800 VDC delivery
Just one AC to DC conversion stage between the grid and the DC backbone optimizes efficiency and aligns with emerging megawatt-rack 800 VDC architectures.
Power continuity
Delivers instantaneous energy from the DC-coupled battery while generators, alternate sources or controlled shutdown strategies respond.
Repeatable deployment
Creates a factory-integrated electrical building block that can be installed, commissioned, serviced and expanded in modular increments.
Built-in N+1 redundancy
Redundancy for both the Zenius immersion-cooled battery technology and the rectifier.
Primary operating modes
Independent power-conversion sections and fault isolation allow ZettaWatt™ Power Platform to maintain full rated output if one section becomes unavailable, supporting uninterrupted operation during equipment faults or planned maintenance.
