The Transmission System Operator Cyprus wishes to inform the public that the Upgrading of the Supervisory Control and Data Acquisition/Energy Management System (SCADA/EMS) is currently in the implementation phase. The project is co-financed by the European Regional Development Fund (ERDF) of the European Union, under the Operational Programme Sustainable Development and Competitiveness . The project falls under the Priority Axis Information Society and Innovation with Specific Objective the Promotion of the Use of Information and Communication Technologies and under the Category of Interventions Development and Use of Information and Communication Technologies for the Provision of Public Utilities Services to Citizens in relation to ensuring the reliability and security of the Transmission System of Electrical Energy.
The SCADA/EMS System is a complicated supervisory control system used for the management of the Electrical Power network of the whole of Cyprus. Through this system, the National Energy Control Centre of Cyprus monitors and controls the electrical power network in real-time. It is a mission critical system of high importance for the country.
The explosion on the 11th of July 2011 at a naval base severely damaged the neighbouring Vassilikos Power Station and caused the sudden loss of more than half of the system generation capacity of Cyprus. The SCADA/EMS System was the main tool which averted a total black out, that would have caused many other serious catastrophic consequences to the island.
Furthermore, during the management of the energy crisis and the emergency situation that followed the destruction of Vassilikos Power Station, the application of the 2-hour rota (cyclic) load shedding scheme would have not been possible without the existence and operation of the SCADA/EMS System since and as a consequence a total blackout would not have been avoided. Through the SCADA/EMS System, a large number of tele-control commands were issued and performed on the Medium Voltage Automatic Circuit Breakers, without the need for staff to be present at Transmission and primary Substations.
Severe ageing incapacities were observed on the SCADA/EMS System, which completed ten years of operation in March 2014. Considering the rapidly rising demands of network Management, especially due to the increasing development of Renewable Energy Sources (RES) and their connection to the Electrical network, the SCADA/EMS System in many cases, could not respond efficiently and effectively. The Cyprus TSO identified the need for the upgrading of the SCADA/EMS System to a later release and in 2012 submitted a proposal for co-financing the project by the European Regional Development Fund (ERDF).
