The synchronization of the four units was done in phases. While unit 1 and 3 were synchronized in September 2013, unit 2 was synchronized in November 2013. Despite limited water availability during commissioning and other challenges in terms of a difficult terrain, Alstom was successful in completing the synchronization of the fourth unit in February 2014 as targeted by the customer. All the four units were declared by the customer in commercial operation from 1st March 2014.
Alstom was awarded the Uri II HEP contract by NHPC in 2007. The scope of work included turnkey execution of the electro-mechanical package comprising of hydro turbines, generators and auxiliaries.
Last year, the hydro project achieved a major milestone when all four 60 MW Francis vertical turbines installed by Alstom completed the spinning of the four units in less than twenty four hours. The 240 MW hydropower project aims to use downstream water discharge of 480 MW Uri-I (already running) hydro project for power generation. It will also provide additional stability to the northern transmission grid.
