 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.

6. 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.
