Congestion in electricity transmission systems is a common problem all around the world, Georgia included. Two types of congestion are observed in the power sector; physical and economic. Physical congestion occurs when a transmission system is not adequate to supply an increasing amount of electricity. Economic congestion appears when prices in one region are different from those in another region, while cheaper electricity cannot be sold to the region with high prices. Both types of congestion are problematic for Georgia.

Physical congestion is prevalent in Georgia because electricity is heavily used in the eastern part of the country, while most power plants are in the west (such as large HPPs). Economic congestion occurs because cheap electricity in western Georgia cannot always be delivered to eastern Georgia, where power plants produce more expensive electricity.
