In Chamba district, two major hydroelectric projects - the 198 MW Baira-Siul project and the 540 MW Chamera project - have been completed keeping the environmental aspects in focus. The projects were constructed by the National Hydroelectric Power Corporation (NHPC), which has all along been making efforts to ensure that its projects are eco-friendly. Suitable environmental measures were taken with the result that the construction work proceeded without hurdles being created by environmental lobbies.
