Turkey Strengthens Connection to the West

Turkey's first national load dispatch system was installed and commissioned in the 1980s. Supplied by a Westinghouse/Telettra consortium, the Wesdac32 system included supervisory control and data acquisition (SCADA) and an energy management system (EMS). The Turkish Electricity Transmission Co (TEIAS) is owner and operator of the electricity transmission system in Turkey, as well as operator of the country's electricity market. In the early 2000s, the Wesdac32 SCADA/EMS system was replaced with the SINAUT Spectrum version 4.3 SCADA/EMS system from Siemens. The SCADA system collects real-time data from RTUs located at about 200 power plants and substations, out of approximately 650 power plants and substations, connected to the Turkish national electricity network. Currently, TEIAS is continuing to expand the SCADA/EMS system to the remaining part of its 154-kV subtransmission network. TEIAS also plans to install around 150 more RTUs in the existing substations connected to the 154-kV subtransmission network within the areas of the existing six regional control centers.
