Real-time diagram editor for BESS plant operations
Fluence, a global leader in energy storage and grid optimization, needed a way for battery energy storage (BESS) domain experts – not developers – to create and customize the visualizations they use every day to commission, monitor, and operate plants. The diagram editor was first applied to the plant's primary electrical diagrams – manual, slow to update, and dependent on developers for every change. The same need extended to alarm pages, plant-wide dashboards, and other operator-built views – all of which previously required code changes to the product.
Fluence Energy, Inc. is a leading provider of battery energy storage products, services, and optimization software across 47 markets. It empowers utilities and energy providers to scale renewable energy assets for a resilient, sustainable grid.
A digital solution that would allow operators and engineers to independently create, edit, and visualize single line diagrams and control logic in real time – without relying on custom development for every change.
Design and implementation of a web-based, real-time diagram editor and control logic visualization, integrated with Fluence’s backend, supporting hundreds of elements and custom workflows.
BESS plant diagramming challenges solved with custom diagram editor
Every BESS plant has its own unique electrical configuration – and its own set of diagrams. Static, manually maintained files couldn’t keep up with that variety, and every new plant turned into a new development project.
Static, manually updated diagrams
The original diagrams were:
Easy filtering and conditional formatting
People wanted to color-code or restyle nodes based on specific data—like changing shapes or fonts when certain conditions were met.
Branch expand/collapse
Users needed a quick way to hide or reveal entire sections of the chart, letting them focus on what mattered most.
Building an interactive diagram editor layer for BESS plant operations
At first glance, the problem looked like a need for a diagram editor. In reality, it required redefining what diagrams represent.
Workshops revealed that diagrams were more than visuals – they were tightly linked to system logic, live data, and decision-making. The scope shifted from drawing to building an interactive layer for power plant operations.
With multiple user types, evolving vision, and complex data, the team iterated throughprototypes and validated flows continuously – adapting to new requirements as theyemerged.
The platform had to be intuitive for operators, yet powerful for engineers. This meant
drag-and-drop interactions, clear system states, and a minimal learning curve – without
sacrificing control.
Fluence needed highly customizable diagrams, advanced features (rules, alerts,
custom views), and support for large-scale electrical systems. The challenge: deliver
flexibility without breaking performance or usability.
Intuitive diagram editor for faster, error-free plant operations
Empowering operators with real-time insight and streamlined workflows
Drag-and-drop diagram editor
Every operator is empowered to build, edit, and reorganize complex electrical diagrams visually – no developer support or specialist training needed. Intuitive interface with rotation, line breaking, and multi-select for rapid workflow.
Live data overlays for electrical system monitoring
Diagrams display real-time values (voltage, SoC, frequency) and system status. Operators see the current state of the plant, enabling instant, data-driven decisions and proactive electrical system management.
Personalized views and asset watchlists
Operators create custom pages and watchlists for specific assets or sites. Filter, export, and monitor what matters most – tailored to every plant’s unique electrical network.
System reliability and automation for large-scale electrical engineering
Scalable, integrated software for secure, compliant, and efficient energy operations
Custom rule manager and automated alerts
Operators can define custom rules for any monitored parameter – trigger alerts, automate workflows, and ensure proactive maintenance. Operators stay ahead of issues and maintain compliance with electrical safety standards.
Scalability for complex power systems
Handles hundreds or thousands of diagram elements without performance loss. Built for the largest, most demanding electrical engineering and energy sector environments.
Seamless backend integration for data consistency
Direct connection to Fluence’s control systems ensures data consistency, security, and operational reliability. Without manual syncing or data silos – electrical engineering software works in harmony with existing infrastructure.
The new operator-first and data-driven standard for diagram management
Now Fluence’s engineers and operators can update diagrams and monitor live plant data instantly. The platform reduced IT workload, improved safety, and enabled rapid adaptation to new sites – setting a new standard for electrical system management.
- Centralized overview
Key metrics – such as node statuses and ownership breakdowns – are consolidated in one place, giving stakeholders a snapshot of the entire structure at a glance. A unified view enables quick assessments and more informed strategic decisions. - On-the-fly updates
Changes to filters, formatting rules, or displayed attributes occur instantly, allowing users to refine data and see results straight away. Real-time responsiveness guarantees that the dashboard always reflects the most current state of the group structure. - PDF export & reporting
Users can export a finalized chart with all applied styles intact, eliminating the hassle of manually recreating or editing diagrams in another tool. An export feature that simplifies reporting helps distribute consistent, professional visuals across teams.
Complex integration for next-level governance
Integrating our advanced diagramming solution with a current setup can instantly improve data management and oversight. The architecture adapts as entity structures evolve – without forcing a costly overhaul.
- Adaptable approach

Each deployment is fine-tuned to an infrastructure, allowing fluid data exchange and minimal extra overhead. - Low-impact rollout

An iterative release strategy introduces new features without pausing essential operations, so productivity remains high. - Tailored connectivity

Specialized endpoints and data formats are accommodated, making the solution an organic part of a tech stack. - Built for expansion

As a corporate network scales, the resilient architecture maintains top-tier performance under heavier loads.
Discover the impact of an interactive structure chart
A fully customizable diagram allows governance teams to see ownership structures and relationships at a glance, reducing confusion and speeding up evaluations.
Real-time data updates and on-the-fly filtering ensure that users work with current information—helping them act swiftly and confidently.
Built-in features like conditional formatting and PDF export make it easier to maintain regulatory standards, audit trails, and consistent reporting.
