03.2Success story · Energy-Tech
enercity
An EMS product that serves three workplaces.
PULS is a utility's own energy management product. Customers, trade partners and service technicians work on the same asset data, with different tasks and permissions. Lipsia Digital designed and delivered the product.
Applications
3
Customer app, trade partner portal and service application on one platform.

02Starting point & goal
Three roles, one data base.
enercity wanted to offer energy management as its own digital product rather than buy it in. A customer app alone is not enough for that: without processes for trade partners and service, there is no operating model. The key question was how much process belongs in the software.
- Connect assets and device classes reliably
- Give customers a product that needs no training
- Make trade partners operational in sales and installation
- Put remote diagnosis before the site visit
- Bind permissions to roles, not to applications
03Roles
Each role gets its own view.
The trade partner needs the list of assets they look after, service the fault with its history, the customer the state of their system and a way to get support. Everyone works on the same data; one shared permission model controls access. It is described once and applies in all three applications; new tasks are configured rather than coded.
Model
One source
Roles and permissions are held centrally in the platform.
Data
1
One asset, one record. No reconciliation between portals.

For customers it stays an app
Self-supply, operating state, monthly balance and a direct route to service. Customers never see the role model behind it.

With context
The request already carries asset and device data.

04Commissioning
Commissioning as a process.
Mistakes during commissioning cause faults later. In PULS it is therefore a process with states: partner, service and customer see the same progress and the same open points.
Service
Remote first
Reachability, backfilled readings and controller response, checked before the visit.

A checklist instead of phone calls
Created, devices detected, metering point linked, controller active, customer approval: progress is documented in the system. Anything missing appears as an open point in the application where it gets solved.

Meter data
No metering point, no operation. The notice goes to the partner, not the customer.
Faults arrive with a history
A request from the app contains the asset, the device and the last readings. Service sees the history and can resolve some cases without a site visit.
