After nearly half a century, Damodar Valley Corporation (DVC) is taking a relook at the hydel power generation potential in its designated catchment area, spreading over West Bengal and Jharkhand. The corporation recently appointed the Central Water Commission of India (CWC) for a comprehensive study of the Damodar river valley region. The study report would also provide inputs on the siltation problem, which is affecting the flood prevention capacities of the dam and barrage system under DVC.
