The controversial Kudankulam nuclear plant in India’s Tamil Nadu state has begun producing electricity after years of delays and protests, officials say.
The plant was connected to the grid on Tuesday, Press Trust of India reported.
In May, India’s Supreme Court ruled that the power station could start operations as it was “safe and secure”.
Opponents of the plant, which is on the coastline hit by the 2004 Asian tsunami, fear a disaster similar to the one at Fukushima in Japan in 2011.
Last year, Kudankalum was the scene of mass protests over safety concerns.
The plant is one of many that India hopes to build as part of its aim of generating 63,000 MW of nuclear power by 2032 – an almost 14-fold increase on current levels.
The plant became operational during Prime Minister Manmohan Singh’s two-day visit to Moscow.
The law stipulates that nuclear firms aiming to set up plants in India will have to pay huge sums of money in case of an accident and Delhi and Moscow have not been able to agree on this clause.
