Electricity arrives through the Kavkasioni 500-kilovolt power transmission line.
In addition, the company has resumed the same amount of electricity imports from Armenia through the Alaverdi 220-kilovolt power transmission line.
TELASI buys from Russia electricity at 2.6 cents, from Armenia at 2.7 cents per kilowatt.
Supplies from both the countries were suspended during the spring-summer period for Georgia's being able to meet the domestic demand during the time.
In winter Tbilisi needs 500 megawatts.
The import of electricity enables cutting water consumption from the water reservoirs of the Inguri and other Georgian hydropower stations, TELASI said.
TELASI's import of 200 megawatts is enough for smooth power supply to the Georgian capital, Tbilisi.
The other 300 megawatts produced from firing natural gas arrive from the ninth power unit of the Tbilisi-based power generating facility, owned by the RAO Russia's UES Company.
