It has four units. The fourth unit went critical on 27 November 2010.[2] The two oldest units comprise the west half of the site and the two newer units are adjoining the east side of the site. The older four units are small-sized pressurized heavy water reactors of 220 MW gross.

History

On 27 November 2010 the Kaiga Atomic Power Station unit 4 of 220 MW capacity became operational.[3]

On 19 January 2011, unit 4 with 220 MW capacity was connected to the southern power grid at 01:56 hours. With this, the total capacity rose to 880 MW gross making it the third largest in India after Tarapur (1400 MW) and Rawatbhata (1180 MW). The unit, fueled by indigenous uranium, will supply electricity to Karnataka, Andhra Pradesh, Kerala, Tamil Nadu and Puducherry.[4]

In December 2018, it got the distinction of setting a world record of continuous operation among all nuclear power plants. As on 10 December 2018, KGS-1, which was synchronized to India's Southern grid on 13 May 2016, continues to operate for a record number of 962 days. Previous record of continuous operation was held by Unit 8 of Heysham II, which operated from 18 February 2014 to 15 September 2016 for a record number of 940 days.[5][6]

Two PHWR unit, each with a 700 MW capacity, have been planned for this location.[7] As of February 2017 pre-project activities have begun for them and if everything goes as planned the first of the two will become critical around 2024–25.[8]
