Power generation in all major hydroelectric projects of Himachal Pradesh, including the 1,500-MW Nathpa-Jhakri project, the 412-MW Rampur project, both run by the Sutlej Jal Vidyut Nigam, and the JSW-promoted Karcham-Wangtoo project, has dropped by 75% to 80% due to reduced water discharge in rivers amid freezing cold conditions in the higher reaches.
Due to low production, the state is buying power through banking and bilateral arrangements with neighbouring states to meet its domestic demand for all categories of consumers.
Power projects in Himachal Pradesh generate 270 lakh to 275 lakh units of electricity daily in summer. However, the production drops to 68 lakh units in winter.
