A Smart Assistant For System Operators

OperatorFabric is a modular, extensible, industrial-strength platform for use in electricity, water, and other utility operations.

It aims to facilitate operational activities for utilities in two ways :

In addition, the following features are available: internationalization, light/dark mode for the UI, realtime connected users supervision, authorization mechanism.

Integration with existing IT systems is an overarching concern: support of Firefox and Chromium-based browsers, docker deployment, communication with business applications via REST API or Kafka, integration with external authentication systems (via OAuth2), monitoring via Prometheus endpoints.

What does it do

To perform their duties, an operator has to interact with multiple applications (perform actions, watch for alerts, etc.), which can prove difficult if there are too many of them.

The idea is to aggregate all the notifications from all these applications into a single screen, and to allow the operator to act on them if needed.

Feed screen layout

These notifications are materialized by cards sorted in a feed according to their period of relevance and their severity. When a card is selected in the feed, the right-hand pane displays the details of the card: information about the state of the parent process instance in the third-party application that published it, available actions, etc.

In addition, the cards will also translate as events displayed on a timeline (its design is still under discussion) at the top of the screen. This view will be complimentary to the card feed in that it will allow the operator to see at a glance the status of processes for a given period, when the feed is more like a “To Do” list.

Part of the value of OperatorFabric is that it makes the integration very simple on the part of the third-party applications. To start publishing cards to users in an OperatorFabric instance, all they have to do is:

OperatorFabric will then:

Another aim of OperatorFabric is to make cooperation easier by letting operators forward or send cards to other operators, for example:

This will replace phone calls or emails, making cooperation more efficient and traceable.

For instance, operators might be interested in knowing why a given decision was made in the past: the cards detailing the decision process steps will be accessible through the Archives screen, showing how the operators reached this agreement.

Open source

OperatorFabric is part of the LF Energy coalition, a project of The Linux Foundation that supports open source innovation projects within the energy and electricity sectors.

OpFab is an open source platform licensed under Mozilla Public License V2. The source code is hosted on GitHub in this repository : operatorfabric-core.

Technology stack


OperatorFabric is mostly written in Java and based on the Spring framework. This makes writing and integrating software for a simplified and better coordination very easy.
