Atomic Energy Organization of Iran (AEOI) Director Ali Akbar Salehi has said the Bushehr nuclear power plant will be connected to the national grid by February 20.
Speaking to ISNA news agency, Salehi said some Russian officials will also attend the ceremony.
When Bushehr nuclear power plant is first connected to the national grid, the reactor will be producing 400 megawatts of electricity and within two or three months it will reach 100 percent of its capacity and produce 1000 megawatts of electricity, which accounts for one-fortieth of the electricity output of the country.
Salehi who has also taken over as interim foreign minister expressed hope that the plant would be able to produce 1000 megawatts of electricity by mid-April.
He said making a nuclear power plant fully operational usually takes 9 months.
The power plant was launched in August 2010 as engineers loaded the first of 163 fuel rods into the reactor under the supervision of the International Atomic Energy Agency.
The plant, which is located near the port of Bushehr on the coast of the Persian Gulf, will produce 1000 megawatts of electricity once all the fuel rods are loaded into the core of the reactor.
