The problem
Why this matters
Buyer pain first — architecture second. If the problem is not real, the stack is irrelevant.
MW-scale GPU racks outrun legacy AC/low-VDC power distribution. Cooling and power density are the bottleneck.
Buyer jobs
- · Deploy dense power + cooling modules faster than traditional fit-out
- · Pair GPU containers with BESS on a shared DC architecture
MW-scale GPU racks outrun legacy AC/low-VDC power distribution.
Cooling and power density are the bottleneck.
Architecture notes
- · 20 ft containerised GPU + cooling modules on the DC BUS (design target)
- · BESS buffering for power density and grid constraint management
Architecture
How Joule Junction addresses it
Deployment scale 5–50 MW. The solution traverses these energy-flow stages on the open DC platform.
Energy-flow path
Platform
Three layers. One stack.
Every solution runs on DC BUS, Metering, and Energy Management — the same open architecture at every scale.
DC BUS
The physical DC backbone. SST, BusWay, PCS, protection, and grid interface in one architecture — current flagship 800 V DC.
- Solid State Transformer (SST)
- DC BusWay
- Power Conversion System (PCS)
Metering
IEEE 2030.5-native data layer. Measurement at every point — grid edge, DC bus, load, charger.
- IEEE 2030.5 Smart Meters
- DC Energy Meters
- Sensors & Data Acquisition
Energy Management
Software that optimizes. The layer customers evaluate first.
- Forecasting
- Tariff optimisation
- Battery optimisation
