The digitisation of grid operation is constantly increasing and requires continuous optimisation, e.g. in terms of outage planning coordination and adequacy analysis – both aspects are integral parts of the Annual Work Programme 2020 of the European Network of Transmission System Operators (ENTSO-E). Two new IT tools to simplify the cooperation of transmission system operators (TSOs) and allow better anticipation of the balance between supply and demand are available since this spring and currently used by a total of 38 TSOs. Under the coordination of ENTSO-E, the “Outage Planning Coordination (OPC) Pan European Merge Tool” and “Short Term Adequacy forecast (STA) tool” have been developed jointly with the Munich based Regional Security Coordinator (RSC) TSCNET Services playing a leading role in the development of OPC.

Tahir Kapetanovic, Head of the Control Centre of TSCNET shareholder APG, the Austrian TSO, and Chairman of the ENTSO-E System Operation Committee, comments on the latest success: “The cross-border coordination and intensive cooperation of all national TSOs are the preconditions for a smooth functioning of the power supply across the European Union. By means of such jointly developed tools, uniform norms and standards for network operation can truly be implemented into practice.”

The launching of both tools may be considered as further evidence of the well-established pan-European cooperation of European TSOs and RSCs. STA enables a short to medium-term prognosis for load management, which is particularly important in view of the energy transition to compensate for the volatility of renewable power generation with innovative solutions and to integrate them smartly into the system. With the OPC Pan European Merge Tool, concept originally developed by TSCNET Services, the TSOs and RSCs can plan power outages on a regional level, including coordination of maintenance and inspections. Electricity supply and trade are thus ensured despite the necessary shutdowns.

The need for OPC on a pan-European level across the different RSCs and the corresponding concept of a harmonised outage planning process dates back to 2012, when the TSOs of the central and eastern European regions established the TSC (TSO Security Cooperation) area. The Medium-Long-Term Operational Planning (MLTOP) project of the TSC TSOs, which was started at that time, is the origin of the OPC tool. When TSCNET Services emerged in 2015 from the joint TSC TSO office in Munich, the MLTOP project was carried on by TSCNET for prototype and business process development in coordination with the TSC TSOs. In the same year, ENTSO-E launched the TSO Project for Coordination Strategy Implementation with the Regional Security Coordination Initiatives (RSCIs), which was continued later under the EU System Operation Guideline (SO GL). This extended the scope of the MLTOP project from the TSC area to the whole of Europe and it became the foundation of the OPC project.

In December 2017, the prototype resulting from the OPC project, owned and developed by TSCNET, went live on a pan-European scale and provided the initial service to all TSOs and RSCs in Europe. Now the prototype tool has been converted into and replaced by a fully-fledged industrial tool: the OPC Pan European Merge Tool, whose development represents a unique success story for TSCNET services and the associated TSOs. What was once an idea for cooperation in the TSC area has been further developed and prototyped by TSCNET in close cooperation with the TSOs and has now evolved into an industrialised pan-European tool used by the outage planners of 38 TSOs and four other RSCs.

TSCNET Services as a major contributor
The OPC project and its development process is a good example of what can be achieved through intensive cooperation between TSOs and RSCs. TSCNET successfully took the lead in this cooperative effort and managed not only to develop services on a pan-European level, but also to successfully coordinate with other stakeholders (RSCs, TSOs and ENTSO-E) and convince them to be part of the success. The development of the OPC project fits perfectly with the narrative of the definition of TSO, RSC and European coordination: The RSCs provide services to TSOs by setting up business processes and tools with their unique regional and technical expertise, thereby combining the knowledge of the individual TSOs – and if the concept has proven to work, they scale it up for the rest of Europe and centralise the infrastructure if necessary (and requested by ENTSO-E).

TSCNET is indebted to its Service Analytics & Quality Manager and responsible OPC Project Convener, Jayaram Anandha, to Sonja Tomić, Junior Operations Manager, and Jorge Alves, Operations Manager, for their input in the development of this highly efficient tool. The predecessor as OPC Project Convener, Tin Bobetko, and Michalis Stamoulis jointly led the business and data standard development of the OPC prototype tool, which was running perfectly until the industrialised version went live.
