ÇALIK YEDASs’ PRIORITIES IN THE ELECTRIC DISTRIBUTION SECTORÇALIK YEDASs’ nvestment budget is 100 MTL/yearStrentghten the existing network infrastructure Increase the network capacity and operation flexibilityProve the sustainability for the supply ,technical quality and customer satisfactionDecrease the technical and commercial losses in the networkÇALIK YEDAS IS AWARE OF ONLY STRENGTHENED NETWORK IS NOT ENOUGH FOR THE SUCCESS OF NETWORK OPERATIONS.SMART MANAGEMENT OF THE NETWORK WILL ADD A VALUE TO WHOLEINFRASTRUCTURE INVESTMENTSÇALIK YEDASs TECHNOLOGICAL INVESTMENTS SAP has been activeted with all modules in May 2011 SAP-ISU (Industrial Solutions For Utilites) has been completed in October ,2012All customer numbers,meters, addresses and LV network connectivities has been transferred into ISU system from the existing Abone.Net softwareCurrently, billing, customer/metering informations , customer connections, customer complaints/requirements are managed and reported through these IT systems.The cost of these systems is roughly 18 MTL. The mechanical meters has been replacing with the digital ones since 2011. (Total 611.000 meters)

ÇALIK YEDASs TECHNOLOGICAL INVESTMENTS

AMR infrastructure has been founded in 2012. 60.000 customer meters will have been included in AMR system by the end of 2015. ( Forecasted budget is 28 MTL) Whole HV and LV network has been modelled and analysised in digital environment (Dig Silent) to determine 5 and 10 years network investment requirements. SCADA/DMS Project started in September,2012 and it’s still going on.Project Budget is 13 MTL for 2012 and 2013 ( 5 MTL has been spent in 2012)Project is being executed by General Electric Digital Energy.133 numbers of Central area substations ( 900 feeders) in 5 provinces will have been controlled and monitored by the end of 2013.DMS Modules which will be used in DMS System Outage Management Load Flow Analysis Network Management Fault Restoration and Isolation

SCADA/DMS System will be integrated with SAP/CRM/ISU /PM and GIS.

ÇALIK YEDASs TECHNOLOGICAL INVESTMENTS

Whole customer addresses and LV connectivities has been included into GIS system in 2012. Remaining HV connectivities and line characteristic parameters/lenghts will have been included in GIS system by the end of 2013.Total budget of GIS system is 12 MTL

ÇALIK YEDASs’ SMART GRID VISION BY THE END OF 2015 Realize a strong integration between SAP/ISU/CRM ,GIS, AMR and SCADA/DMS for the effective network and workforce management Include the all meters of important customers into AMR system Establish a strong asset management system using GIS Establish asset risk management system using GIS and SCADA/DMS Develop and adapt the existing technological systems considering the electrical vehicles and distributed generation systems

EXPECTATIONS EMRA Awarness of successful technological investments require enough time to realize them ( Process analysises, system conceptive,etc.) Give reasonable time to DisCOs to complete the whole integrated distribution management systems instead of applying penalties. Revise the investment budgets as DisCOs can realize their technological systems accordingly international quality standards. Resolve the uncertainity on the technological investments which have been realized prior to unbundling.USTDA Establish a strong technology connection between DisCOs in US and Turkey Lead DisCOs in Turkey to make a proper IT requirement analysis and determine priorities Lead DisCOs to transfer the proper technology at the right time.TECHNİCAL SUPPORTERS Pay attention the proper technological requirements of DisCOs more than commercial profits Make workshops with DisCOs and direct them to advise the best technological solutions.
