Himachal Pradesh CM Inaugurates First Battery-Integrated Solar Project in Spiti Valley.

2 MW solar plant with 1 MWh battery storage to generate 36 lakh units of electricity annually in the high-altitude Himalayan region.
  Himachal Pradesh Chief Minister Sukhvinder Singh Sukhu on Wednesday inaugurated the state’s first solar power project equipped with battery storage at Rongtong, near Kaza in Spiti Valley, as part of development initiatives worth ₹116.28 crore in Lahaul-Spiti district. The 2 MW solar power plant, constructed at a cost of ₹4.42 crore, features a 1 MWh Battery Energy Storage System (BESS) and is situated approximately 3,600 metres above sea level. The project is expected to generate around 36 lakh units of electricity annually. Construction began on May 30, 2023, and the plant was commissioned in December 2024, according to an official statement. The project highlights the potential of solar energy combined with battery storage in remote, high-altitude regions, where reliable electricity supply presents significant challenges. Sukhu described the facility as a symbol of development for Spiti Valley. He also announced that ₹6 crore would be spent to make the Rongtong Hydel Power Project fully operational, strengthening the region’s renewable energy infrastructure.
