The 'Next Generation Control System' project builds on the development cooperation within the internationally recognised, award-winning NEDO project, which established the basis for the collaboration between ELES and Hitachi. It is a pivotal step in the development of advanced functionalities for transmission system control centres.

These functionalities include improved system connectivity and more transparent data exchange.

As part of the project, ELES and Hitachi Energy will develop three key next-generation functionalities:

• The Enterprise Service Bus is a software solution that connects different applications so they can communicate and exchange data with each other, even if they use different languages, protocols or formats. This solution will be implemented in the system for determining operating limits (SUMO).
• Voltage Var Control represents an upgrade to the existing voltage control system, introducing complex functions and advanced control methods.
• The Common Information Model improves the efficiency of network model data exchanged between different systems and organisations, particularly transmission system operators.

The Next Generation Control System project is expected to last two years and is being developed and financed jointly by the two companies. ELES will invest its own funds in the improvements, while Hitachi Energy will develop and verify the agreed functionalities together with ELES. Hitachi Energy will later incorporate the new functionalities into its standard offering, Network Manager EMS.
