3.3.1.3. Planning the transmission system must take into consideration the need to meet 
future demands of all users of the transmission system. 
3.3.1.4. Perspective transmission system must meet the needs of exchanging electricity on the 
electricity market. 
3.3.1.5. Transmission System Development Plan contains data on total consumption and 
generation trends with special emphasis on the significant changes, the emergence of new 
facilities or closing down of the existing facilities of transmission system users.
3.3.1.6. The main objective of the Transmission System Development Plan is to provide to all 
existing and potential users of the transmission system, participants in the electricity market 
and the competent authorities, the following: 
- Comprehensive overview of the transmission system development at a given 
time interval;
- Overview of major changes in the transmission system (list, locations and basic 
characteristics of the transmission facilities that will be reconstructed, 
expanded, built, or shut down, including the interconnection transmission lines). 
3.3.1.7. JSC EMS develops the transmission grid in compliance with the distribution grids, 
and for this purpose cooperates with the distribution system operators. In addition to meeting 
the technical criteria of the transmission system, it shall take into account the following: 
- Quality of electricity supply to distribution facilities that are radially inter-
connected to the transmission system; 
- Provision of reserve line for feeding distribution facilities that are radially 
connected within the distribution system; 
- Need to find economically optimal solution for both system operators.
