The Tarapur Atomic Power Station Units 1 and 2, located on India’s west coast in Maharashtra, are Boiling Water Reactor (BWR) units that marked an important milestone in India’s nuclear energy programme. Commissioned in 1969, these were among the country’s first operational nuclear reactors and continue to supply reliable power to the western grid at one of the lowest generation costs in the nation. Together, the two units have generated over 48,800 million units of energy since commercial operation.

Tata Consulting Engineers (TCE) provided comprehensive engineering and commissioning services, ensuring the safe and efficient performance of the plant. The project set the foundation for future nuclear developments in India and strengthened the country’s energy independence. TCE’s contribution to this early success established its long-term partnership with the Nuclear Power Corporation of India Limited (NPCIL) and reaffirmed its role in building world-class nuclear power infrastructure.
