What Zepben does

Zepben, founded in 2015 and headquartered in Canberra, Australia, develops the Energy Workbench, a Common Information Model (CIM) based network model data platform serving electricity distribution network operators (DNOs). The company addresses the operational and planning needs of DNOs confronting rising distributed energy resources (DER), electrification-driven load growth from electric vehicles and heating, and the limitations of legacy systems not designed for modern generation and load profiles.

The Energy Workbench provides a horizontally and vertically scalable application development environment that exposes a governed yet open CIM data layer through Python and Kotlin SDKs and a GraphQL API. The platform is delivered with a suite of modules including Hosting Capacity Analysis (scalable network-wide power flow with street-level constraint forecasts), EDNAR for planned network access workflows, Curtailment Forecasting, Voltage Compliance Reporting, Capacity Planning, Scenario Modelling, and Duration Curves. Specialized model-builders — the Sincal Model Builder for PSS/SINCAL and the PowerFactory Model Builder for DIgSILENT PowerFactory — automate the conversion of CIM data into planning software models, with both tools reporting approximately 10x productivity gains and weekly automated updates replacing year-old manual snapshots. The core SDK is open-source, and the platform integrates with major DNO data ecosystems including Hexagon, Schneider Electric ADMS (Ecostruxure), GE PowerOn Fusion, GE Smallworld Electric Office, Spatial Eye, and the CGMES interchange format, enabling broad interoperability across utility GIS and ADMS estates.

Zepben generates revenue primarily through enterprise subscription agreements with ANZ distribution network operators, deploying its platform and modules under a recurring software license. The company runs a consultative, sales-assisted go-to-market targeting enterprise utility customers, with pricing undisclosed and negotiated per engagement. Its customer base is concentrated in the Australian and New Zealand electricity distribution sector, where it has deployed the Energy Workbench to support use cases ranging from network planning and capacity analysis through to operational planning, DER management, and dynamic network pricing. Marketing is anchored on the company website and LinkedIn, with no broad channel program; engagement is direct and account-based into the limited ANZ DNO buyer pool.

Direct peers

• DIgSILENT (PowerFactory): DIgSILENT PowerFactory is a leading power systems simulation platform used by DNOs and TSOs. Zepben's PowerFactory Model Builder is built specifically to export into this tool, making them adjacent peers serving the same planning teams with complementary (not fully overlapping) capabilities.
• Siemens PSS®SINCAL: Siemens SINCAL is a major distribution network analysis platform. Zepben integrates with it via the Sincal Model Builder, and both vendors target utility planning engineers for load flow, short-circuit, and DER studies — making them direct comparables for the same buyer roles.
• Survalent Technology: Survalent provides ADMS and SCADA/DMS solutions to small and mid-sized distribution utilities, including in Australia/NZ. It is a direct comparable in the same DNO operational planning and management niche that Zepben's Energy Workbench targets.
• ETAP: ETAP provides power system modeling, simulation, and real-time analytics software used by utilities and industrial customers. It competes with Zepben/DIgSILENT/SINCAL for the network planning analysis budget and serves overlapping engineering personas within DNOs.

Broad incumbents

• Schneider Electric EcoStruxure ADMS: Schneider Electric's EcoStruxure ADMS is a full advanced distribution management suite used by many global utilities. Schneider is also one of Zepben's core integration partners, so Zepben positions itself either as an upstream CIM data layer for Schneider ADMS deployments or a complement for capacity-planning gaps.
• GE Vernova (Smallworld, PowerOn Fusion): GE Vernova's GIS (Smallworld Electric Office) and ADMS (PowerOn Fusion) products represent incumbent CIM/XML sources for many DNOs. Zepben ingests data from both via dedicated ingestors and serves as a complementary analytics layer on top of these GE-managed systems.
• Hexagon (Utilities & GIS): Hexagon provides spatial data infrastructure widely used by electric utilities (e.g., Spatial Warehouse). Zepben's Hexagon Ingestor pulls data directly from Hexagon's data model, positioning Hexagon as both a competitive adjacent player and a core data-source partner.
• Open Systems International (OSI / Emerson): OSI (now part of Emerson's Ovation suite) provides a leading open-architecture EMS/ADMS platform used by utilities worldwide. As an open-architecture ADMS vendor with a CIM-friendly data model, it is the closest structural analog to Zepben in the broader control-room stack.

Emerging players

• Smarter Grid Solutions: Smarter Grid Solutions is a DERMS software vendor focused on DER hosting capacity and constraint management for DNOs. It overlaps directly with Zepben's Hosting Capacity Analysis and Curtailment Forecasting modules.
• Uplight: Uplight provides DER orchestration, customer engagement, and analytics platforms for utilities. It competes at the DER-program and grid-edge visibility layer where Zepben's Energy Workbench also delivers value, particularly in managing customer-owned DER on the distribution network.
