AC brownfield. 800V DC at the rack.
In 90 days — not the next decade. UpGrid is a modular BESS that plugs into the 415V service already at your site and delivers native 800V DC directly to the rack — NVIDIA's reference architecture, behind the meter, without a transformer order or interconnect queue.
The equipment list you skip.
A greenfield 800V DC build threads power through five more subsystems between the utility and the rack. On an AC brownfield, UpGrid collapses that scope into one cabinet behind your existing service — so the line items below never enter your capex plan or AHJ packet.
New MV transformer
Your site is already energized, already approved. No 24-month transformer order.
MV → 800V DC rectifier farm
AC-to-800V DC conversion happens inside the cabinet. No separate rectifier yard.
800V DC switchgear room
DC switching, metering, and isolation integrated into the cabinet footprint.
Standalone UPS
Sub-millisecond ride-through plus multi-hour backup in the same unit.
Diesel backup + fuel yard
No gen-set, no tanks, no fuel contracts, no air permit cycle.
Interconnect upgrade
Everything stays on your side of the service entrance. No new service application, no utility queue.
Three wins on the same system.
UpGrid hits three places in your P&L at once: demand-charge reduction on today's bill, new racks on your existing service, and compute revenue captured years ahead of the utility timeline.
Demand-charge savings
Peak-shave the existing connection — typical 10 MW campus saves ~$960K/yr at $20/kW·mo.
Capacity multiplication
2.5× rack count behind the same meter. +125 racks on a 10 MW / 120 kW-per-rack campus ≈ $33M/yr unlocked GPU revenue.
Time-to-revenue
Deploy 4+ years earlier than the utility timeline. Compounds across the full facility lifetime.
12 line items collapse to 3.
The industry-reference 800V DC greenfield path runs through 12 subsystems from utility to processor. On an AC brownfield, UpGrid keeps what's already on your site (steps 1–3) and what already lives inside the rack (steps 7–12) — and replaces everything in between with one cabinet.
