Operato is a power system operator solutions company from Slovenia and part of ELES Group. Its core product is SUMO. Designed for transmission system operators (TSOs), SUMO dynamically calculates the thermal ratings of transmission lines and transformers based on atmospheric conditions, helping dispatchers move beyond static limits while improving utilization of existing grid infrastructure and operational safety.
SUMO focuses on fully indirect DTR/DLR capabilities: it covers every line span, avoiding blind spots that can result from monitoring only fixed hotspots; supports the enhanced CIGRE model, IEC 60076-related transformer DTR algorithms, uncertainty calculation by confidence level, and short- to medium-term capacity/load forecasts over 3 hours and 56 hours. It also supports overload mitigation under N and N-1 topologies, extreme weather alerts, a reverse DLR algorithm for ice accretion prevention, and extensive archiving and data export. Public materials explicitly state that it can be tightly integrated with SCADA/EMS and provides a third-party extension API.
The website does not disclose plans, pricing, billing models, payment methods, or SLA details. It only shows a βSee it liveβ entry point, so it is unclear whether a free trial is available. For deployment, the page states that SUMO is fully software enabled and does not require sensors to be installed on conductors, while line expansion does not require outages. However, it does not clarify whether deployment is cloud-based, on-premises, or self-hosted. No public information was found on data security, permission management, or compliance certifications.
Its strengths are that the product is closely aligned with real TSO operating scenarios, the team comes from ELES Group and well-known Slovenian institutions, and SUMO has been in operation since 2013. Operato also discloses an implementation case at ELES covering 29 lines, transformers, and phase-shifting transformers. The weaknesses are limited public commercial information, a relatively small number of disclosed customer cases, and the need for further communication on security, deployment, and service support details required for enterprise procurement.
Operato is best suited for transmission companies, grid dispatch centers, capacity planning teams, and security analysis teamsβespecially organizations looking to increase transmission capacity, accommodate renewable energy, and manage extreme weather risks without building new lines.
