Power Infrastructure for the AI Era
Native 800V DC infrastructure built on solid-state transformers — engineered for AI factories, not legacy UPS chains.
The problem
Why existing power architecture fails
Legacy data center power paths stack conversion stages, substation infrastructure, and UPS systems — driving long timelines, high cost, and compounding efficiency losses.
Today — legacy system
Substation
AC/DC Battery DC/AC
LV distribution
Rack conversion
AI compute
- 12–24 month energization timelines
- Expensive substations
- Low efficiency
- Cooling complexity
- Transformer scarcity
The WattAI answer

Capabilities
Engineered for density, speed, efficiency, and scale
WattAI compresses the electrical infrastructure between the grid and AI compute — delivering more power, faster, in less space.
24 MW power block
A standardized, high-capacity power block engineered to feed dense AI compute clusters.
6 MW solid-state transformer
Direct medium-voltage to 800V DC conversion — replacing multiple legacy conversion stages with a single, deployable platform.
800V DC architecture
Native 800V DC distribution reduces conversion losses and total installed cost versus legacy UPS and rack-PSU chains.
Integrated energy storage
On-site storage for resilience, ride-through, and grid-interactive operation.
Faster time-to-power
A pre-engineered platform designed to compress the path from grid connection to live compute.
Smaller footprint
Higher power density per square foot, freeing space for compute rather than electrical gear.
MCG distribution partnership
A distribution partnership extending reach and deployment capacity across markets.
Future deployments
A growing pipeline of AI data center power deployments built on the shared platform.
Built on the shared platform
The same core that powers freight
WattAI is built on Watt Systems' solid-state transformer platform — the same technology that powers WattEV's heavy-duty charging depots.
Platform economics
Less infrastructure between grid and compute
Compared with legacy paths at $2.18/W and 90.7% end-to-end efficiency, WattAI's simplified architecture delivers materially lower installed cost and higher utilization of every watt delivered to compute.
