with Électricité de France under an agreement signed on 10 March 2018. India's government is developing up to 62 additional nuclear reactors, mostly using thorium fuel, which it expects to be operational by 2025. It is the "only country in the world with a detailed, funded, government-approved plan" to focus on thorium-based nuclear power. Renewable energy On 12 August 2021, India's grid-connected electricity generation capacity reached 100 GW from non-conventional renewable technologies and 46.21 GW from conventional renewable power or major hydroelectric power plants.As of 12 August 2021, there are about 50 GW of projects under development, and 27 GW that are tendered and yet to be auctioned. Hydro power The hydro-electric power plants at Darjeeling and Shivanasamudra were among the first in Asia, and were established in 1898 and 1902 respectively. India's potential for hydropower has been assessed to be about 125,570 MW at a 60% load factor. India is ranked fourth globally by underutilized hydropower potential. The estimated amount of viable hydropower varies with improved technology and the cost of electricity generation from other sources. In addition, there is an estimated 6,740 MW of potential for small, mini, and micro-hydro generators and 56 sites for pumped storage schemes with an aggregate installed capacity of 94,000 MW have been identified. In 2020, the power tariff from Solar PV clubbed with pumped storage hydro have fallen below the coal-based power plant tariffs in offering base load and peak load power supply. The installed hydropower capacity as of 31 March 2018 was approximately 45,293 MW, 13.17% of the total installed utility capacity at the time. Small, mini, and micro-hydro generators add another 4,486 MW capacity. The share of this sector operated by public companies is 97%. Companies engaged in the development of hydroelectric power in India include the National Hydroelectric Power Corporation (NHPC), Northeast Electric Power Company (NEEPCO), Satluj Jal Vidyut Nigam (SJVNL), Tehri Hydro Development Corporation, and NTPC-Hydro. Pumped storage schemes offer the potential for centralized peak power stations for load management in the electricity grid. They also produce secondary /seasonal power at no additional cost when rivers are flooding with excess water. Storing electricity by alternative systems such as batteries, compressed air storage systems, etc. is more costly than electricity production by standby generator. India has already established nearly 4,785 MW pumped storage capacity as part of its installed hydro power plants. Solar power The solar energy sector in
