Consortium

Technical discussions in 2014 have shown numerous similarities in technical challenges, therefore the transmission system operators (ELES and HOPS) and distribution system operators (SODO and HEP ODS) of Slovenia and Croatia began to search for joint solutions. The most promising solution appeared to be the establishment of international cooperation in the implementation of smart grids; and the idea of the SINCRO.GRID project was thus born.

Project primarily addressed problems occurring in the transmission grid, therefore it was managed by the transmission system operators. Each operator was responsible for the implementation of proposed technologies in their respective system. The distribution system operators enhanced the observability of the distribution grid by providing aditional information about RES operation, which helped TSOs to improve forecasting for ancillary services. The control centres of distribution and transmission system operators were connected via ICT infrastructure and systems integration (primarily using the semantic model – CIM).

Each operator was responsible for deploying proposed technologies in its system.

ELES, Ltd., Electricity Transmission System Operator (ELES; now ELES, d.o.o., combined transmission and distribution system operator)

ELES has the exclusive right to perform the service of the combined transmission and distribution system operator in the territory of the Republic of Slovenia. With its professional approach, know-how and advanced technology, the Company provides for the safe, reliable and uninterrupted transmission of electricity across Slovenia and beyond its borders. ELES responsibly and sustainably plans, constructs and maintains the Slovenian high-voltage transmission grid on three voltage levels: 400 kV, 220 kV and part of 110 kV. Through strategic innovation projects, the company is developing the transmission grid of the future.

PROJECT PARTNERS

The partners in the project were transmission and distribution system operator from Slovenia and Croatia (ELES, SODO, HOPS, HEP ODS).

Having demonstrated its conformity with EU policies in the field of smart grids, the project was selected in 2016 for co-financing under the Connecting Europe Facility call.
