L&T Power has commissioned and tested the first unit at its Rajpura supercritical thermal plant of Nabha Power in the Punjab state of India.
The two-700MW coal-fired power plant was commissioned on 31 January 2014. According to L&T Power, commercial operations of the plant will significantly increase Punjab's generation capacity making the state power surplus and will enable it to export power to the national grid.
In the final pre-commercialisation tests, the plant has been continuously operated for 72 hours at full peak load of 700MW. The plant has also undergone two sets of ramp up and ramp down tests. During trial operations, the power plant demonstrated near 100% stability.
Foundation stone for the power project was laid on 3 March 2010. The plant went through light up on 5 December 2013 and was dedicated on 8 December 2013.
L&T Power has developed the power plant on a turnkey basis and the plant received 90% of the equipment from L&T group companies.
L&T's joint venture companies with Mitsubishi Heavy Industries, located in the Gujarat state of India, have supplied supercritical boiler and turbine for the power plant.
L&T board member Shailendra Roy noted the company demonstrated its capability as the leading power plant engineering, procurement and construction player in the country with the successful commissioning of the first unit of the Rajpura Plant.
"The timely completion and stable operations further establishes L&T's ability to build large complex engineering marvels of global standards," Roy said.
The company claims that the Rajpura plant is the largest unit of any indigenously manufactured power plant in the country.
