Loadout sizes your BESS, builds your programme, and generates a client-ready proposal — in minutes.
The problem
Joule lets construction teams test different build scenarios so they can understand cost, logistics, and programme impacts before work begins.
Sizing a generator vs BESS hire manually eats hours. You need the number in minutes, not days.
Cable routes, DB positions, load distribution. Passed around as sketches or never documented at all.
Where's the BESS? When does the generator come back? Nobody knows until someone asks.
Hire a 500kVA generator for a 200kVA job and you've wasted thousands. The data was there. Nobody looked at it.
The Joule workflow
From first estimate to final handover — Joule gives your team the data to plan with confidence, not gut feel.
Input your plant list: cranes, hoists, welfare, tools. Loadout calculates peak demand, week-by-week BESS requirements, and a full cost comparison against diesel in seconds.
Deploy is an interactive site plan builder built for electrical contractors. Place DBs, run cables, auto-size everything. Share a PDF that goes straight into the tender pack.
Mobilise gives you real-time visibility of every unit: what's on hire, what's available, and what's coming back. No spreadsheets. No phone calls. No surprises.
