01
Contract and documents
Your flex contract and the paperwork we need to start: grid operator details, signed mandates, the technical drawing of your site.
HOW IT WORKS
Onboarding is not a black box at FlexHub. A structured process with a live dashboard that keeps both you and your installer on board at every step.

PHASE 1 · GETTING CONNECTED
1
Contract and documents
Your flex contract and the paperwork we need to start: grid operator details, signed mandates, the technical drawing of your site.
2
Grid operator
We move approvals through your grid operator's portal. You see the status; we handle the back-and-forth.
3
Installation
Your installer connects the battery. We confirm validation with the grid operator and manufacturer before moving on.
4
Gateway
The device that connects your battery to the markets. Plugged in on site, configured remotely by us.

PHASE 2 · GOING LIVE
5
Datasheet
One document with your equipment's technical details. It unlocks everything after it, so nothing here is optional.
6
Track Documents
We confirm every device on site is reachable and correctly networked, so nothing breaks once trading starts.
7
Technical Integration
Your battery starts talking to our platform, tested against real market signals before a single euro is on the line.

COMMERCIAL TERMS
No minimum capacity, no fixed volume requirement. The asset participates where it makes sense.
One flexibility provider per connection point, but you choose freely per connection point.
No multi-year lock-in. If the collaboration stops adding value, you can leave on short notice.
Your energy contract stays yours. We optimise around it, and we actively advise switching flexibility provider when the market turns in your favour.
ALONG THE WAY
✓ One dashboard. Customer and installer see the same status, at the same time.
✓ One point of contact. Your account manager owns the file end to end.
✓ No silent steps. Every phase above has an owner and a visible status.
