<P> Tarapur Atomic Power Station ( T.A.P.S. ) is located in Tarapur , Palghar , India. Tarapur is the largest nuclear power station in India . It was constructed initially with two boiling water reactor ( BWR ) units by Bechtel and GE under the 1963 123 Agreement between India , the United States , and the International Atomic Energy Agency ( IAEA ) . Units 1 and 2 were brought online for commercial operation on 28 October 1969 with an initial power of 210 MW of electricity , later on this was reduced to 160 MW due to technical difficulties . These were the first of their kind in Asia . More recently , an additional two pressurised heavy water reactor ( PHWR ) units of 540 MW each were constructed by L&T and Gammon India , seven months ahead of schedule and well within the original cost estimates . Unit 3 was brought online for commercial operation on 18 August 2006 , and unit 4 on 12 September 2005 . </P>
