Karun 3 power plant is the largest hydroelectric power plant across the country, enjoying the capacity of generating 2,000 MW electricity. With the water filling of Karun 3 Dam in October 2004, 1000 MW electricity started flowing into the power grid, fulfilling the expected output for the first summer after the commissioning of the reservoir. The supply and flow of electricity by four units of Karun 3 into the national grid, have so far alleviated the concern over increasing consumption in the summer. According to ISNA, four other units of the said power plant are planned to be commissioned by the next summer. Over 650 million Watts of electricity per hour has been so far produced since commissioning the first unit of Karun 3 in early 2005. PIN/MNA
