Operato

What Operato does

Operato d.o.o. is a Slovenia-based private software company that develops the SUMO Dynamic Thermal Rating platform for high-voltage electricity transmission operators. SUMO calculates real-time and forecast thermal ratings for overhead power lines and power transformers using high-resolution microscale weather modeling, computing span-level ampacity from atmospheric conditions without requiring dedicated field sensors. The platform was originally developed inside ELES, Slovenia's national Transmission System Operator, and has been in daily production operation at ELES since 2017; Operato was spun out of ELES in 2021 to commercialize the technology externally. Operato extends SUMO with native modules for Dynamic Transformer Rating (DTR) and Line Anti-icing (inverse DLR), and supports span-level forecasts up to 56 hours ahead for operational planning and N-1 contingency management.

SUMO integrates directly into operator control rooms through standard utility protocols — ICCP, IEC 60870-5-104, DNP3, and OPC UA — providing ratings, alerts, and operational limits to SCADA/EMS environments. The product is hardware-agnostic and vendor-neutral, integrating with any weather station, sensor, or SCADA system, and exposes open REST APIs plus an integration bus for third-party extensions. Reported customer outcomes include 15-40% transmission capacity uplift through dynamic thermal rating, with deployments covering more than 3,500 km of transmission lines across seven grid operators in Slovenia (ELES), Croatia (HOPS), Greece (IPTO), Lithuania (Litgrid), Canada (AESO, AltaLink), and the United States (PG&E via EPRI). Operato is ISO 9001, ISO 14001, and ISO 27001 certified (with the 27001 scope explicitly covering the electricity sector), conforms to IEC 62443-3-3 Security Level 3, and in 2026 was awarded the EcoVadis Platinum medal for sustainability performance.

Operato sells to transmission system operators and major investor-owned utilities through direct enterprise field sales, with an extended sales cycle that typically involves pilot projects, live platform walkthroughs, and a potential-benefit analysis before full deployment. The revenue model is subscription/recurring software licensing with custom pricing tied to grid size, number of lines and transformers, and deployment scope; pricing is not publicly disclosed. Operato is an SME and a subsidiary within the ELES Group, with Andrej Souvent serving as CEO.

Core offering

Operato develops and licenses the SUMO Dynamic Thermal Rating platform, a software system that calculates real-time and forecast thermal ratings (ampacity) for power transmission lines and transformers using high-resolution microscale weather modeling. The platform is hardware-agnostic and integrates with SCADA/EMS systems through standard utility protocols, enabling transmission system operators to safely unlock 15-40% more capacity from existing grid infrastructure without new construction.

Product overview

Operato offers the SUMO Dynamic Thermal Rating platform, a unified solution comprising core products and native modules. The SUMO platform serves as the foundation, providing real-time and forecast thermal ratings for power infrastructure. Three primary offerings operate within this platform architecture: Dynamic Line Rating (DLR) calculates span-level ampacity for overhead transmission lines using microscale weather modeling without requiring field hardware; Dynamic Transformer Rating (DTR) extends thermal rating calculations to power transformers as a native module sharing the same operational environment; and Line Anti-icing applies inverse DLR (minimum-current calculations) to prevent ice accretion, also shipped as a native platform module. All three products share the same weather modeling engine, control-room integration, continuous archive, and analytics capabilities within a single platform.

Products and services

• SUMO Platform SUMO is Operato's Dynamic Thermal Rating platform that calculates real-time and forecast thermal ratings for power lines and transformers. It increases grid capacity by computing span-level ampacity from atmospheric conditions, supporting SCADA/EMS integration with full N and N-1 contingency awareness. Deployed since 2017 with continuous production operation.
• Dynamic Line Rating (DLR) Real-time and forecast thermal ratings for overhead transmission lines calculated span by span from high-resolution microscale weather modeling, with no field hardware required. Supports CIGRE TB 601 and IEEE 738-2023 standards. Designed for transmission system operators seeking to safely increase line capacity.
• Dynamic Transformer Rating (DTR) Real-time thermal rating and loading forecasts for power transformers calculated from loading and ambient conditions. Shipped as a native module within the SUMO platform alongside Dynamic Line Rating, sharing the same operational environment.
• Line Anti-icing (Inverse DLR) Inverse Dynamic Line Rating module that calculates minimum current required to prevent ice accretion on conductors. Operates as a native module within the SUMO platform with weather alarm integration, designed for transmission operators in cold-climate regions.

Broad incumbents

• Hitachi Energy: Global supplier of transmission equipment, control systems, and grid management software to TSOs. Overlaps with Operato in EMS/SCADA-facing TSO software and grid-enhancing technologies.
• GE Vernova (GridOS): Provides GridOS and broader transmission solutions to TSOs globally. A broad incumbent competing for grid-management, orchestration, and increasingly DLR-related budgets.
• Siemens Smart Infrastructure: Major grid technology vendor with EMS/SCADA, grid management software, and increasingly Grid Enhancing Technology offerings. Competes broadly with Operato for control-room and grid-management wallet share at TSOs.
• Schneider Electric (EcoStruxure Grid): Supplies grid management software and control room solutions to utilities and TSOs. Competes broadly for grid-operations software spend that Operato also targets with SUMO.

Direct peers

• LineVision: US-based provider of sensor-based Dynamic Line Rating and grid analytics for transmission operators. Directly competes with Operato in selling DLR and related grid-enhancing technologies to TSOs and utilities across North America and Europe.
• Smart Wires: US-based provider of modular power flow control, a complementary Grid Enhancing Technology sold to the same TSO/utility buyers as Operato's SUMO platform.
• Ampacimon: Belgian sensor-based Dynamic Line Rating vendor serving European TSOs. Direct competitor to Operato, addressing the same operational pain point of unlocking transmission capacity.
• Heimdall Power: Norwegian provider of Neuron sensor-based DLR and grid analytics for TSOs. Directly competes with Operato in the European transmission market with a hardware-attached DLR approach.

Emerging players

• Grid20 (Entegra Solutions): Provider of transmission analytics and Dynamic Line Rating software for utilities. Comparable in offering software-based DLR and grid analytics to TSOs, though with a different deployment footprint.

Others

• Environmental Systems Research Institute (ESRI): Provider of GIS and spatial analytics used by TSOs and utilities for grid planning. Adjacent rather than directly competing, but the microscale weather modeling underpinning SUMO operates in a similar geospatial-data domain.
