Kudankulam Nuclear Power Plant (or Kudankulam NPP or KKNPP) is the largest[3] nuclear power station in India, situated in Kudankulam in the Tirunelveli district of the southern Indian state of Tamil Nadu. Construction on the plant began on 31 March 2002,[4] but faced several delays due to opposition from local fishermen.[5][6] KKNPP is scheduled to have six VVER-1000 reactors built in collaboration with Atomstroyexport, the Russian state company and Nuclear Power Corporation of India Limited (NPCIL), with an installed capacity of 6,000 MW of electricity.[7]
Unit 1 was synchronised with the southern power grid on 22 October 2013 and since then, has been generating electricity at its warranted limit of 1,000 MW.[8] The original cost of the two units was ₹ 13,171 crore, but it was later revised to ₹ 17,270 crore (US$2.6 billion). Russia advanced a credit of ₹ 6,416 crore (US$0.97 billion) for both the units.[9] Unit 2 attained criticality on 10 July 2016 and was synchronised with the electricity grid on 29 August.
In 2015, Nuclear Power Corporation Ltd (NPCIL) announced a price of ₹ 4.29/kW·h (6.4 ¢/kW·h) for energy delivered from Kudankulam nuclear power plant.[10]
The ground-breaking ceremony for construction of units 3 & 4 was performed on 17 February 2016. Due to technology changes, inflation and insistence of the supplier and operator for additional liability insurance the construction cost of units 3 & 4 amounted to twice the cost of units 1 & 2 and was later revised to be ₹39,849 crore (US$5.38 billion).[11][12][13]
A budget of ₹49,621 crore (US$6.7 billion) has been approved for construction of Units 5 & 6.[11]
