• The Technical Information Department is in charge of development, implementation and operation of the Remote Terminal Units and Automation Meter Reading including preparation of tender documents, purchase, installations and putting into operation of new systems and regular maintenance of the entire Technical Control System having two services – SCADA/EMS and Service of Metering.

Investment program

In the course of 2008 the department of TI was working on implementation of few projects financed by the World Bank and the European Bank for Reconstruction and Development, respectively. It was the WB ASCEE APL-3 Macedonian Project: Package 9-Consultantcy services on drafting of Tender documentation for the needs of splitting up from the Distribution Company. Evaluation report was produced and delivered to the Bank for approval. The report was approved and accepted in 2009.

Within the framework of preparing backgrounds in terms of Package 10, Lot 1 (Procurement and installation of Remote Terminal Unit and measuring converters) and Lot 2 (Procurement and Installation of new Substation Control Systems), site visits to Substations were made subject to splitting up from EVN and also proposals generated for technical solutions for supervision and control of these SSs.

EBRD Package 2-drafting of tender documentation, announcement of Invitation to Tenders on delivery and installation of new control units for SS Skopje 4 and SS Dubrovo (supervision and control of 400 kV in these to SSs). The contract was signed in 2009.

EBRD Package 3-collection of background for supervision and drafting of Tender Documentation for delivery and installation of new supervision and control systems in SS Bitola 2 and SS Skopje 1. 

The implementation of a part of the above stated projects is related to the extension and upgrading to the existing systems in SS. For the needs to extend the functions of the existing Chronological Register of Events in SS Skopje 4 and SS Dubrovo up to complete SCADA Systems, tender documentation was prepared, operating requirements and technical specifications, respectably.
One of the basic TI department’s activities was the splitting up between MEPSO and EVN (preparation of operating requirements, drafting proposals for allocation of equipment, overview in the existing conditions with analysis of possible space division etc.).
