WORKSHOP ON HYDRO POWER DEVELOPMENT
Date: 17.09.2018
Venue: India Habitat Centre
Presentation By

Director (Tech.), NHPC
Benefits of Hydro Projects
●Quick start-stop capability.
• Highest ramping rate (typically 100 MW/min) in real time among all other sources of generation.
Hydro has more inertia and most suited for grid stability during transient faults.
• Spinning reserve.
Provides MVAr needed for voltage stability of the grid.
• Needed for black start
Primary frequency response and regulation.
Benefits of Hydro Projects
● Hydro has a very low price per megawatt hour in comparison to the battery costs over complete life cycle
• The role of Pumped storage hydropower plants is twofold –they balance the grid for demand-driven fluctuations as well as generation-driven fluctuations.
Hydro plants have a long life- Civil structures -100 years and E&M equipment -35 years.
• Hydro projects lead to development of infrastructure in remote areas and building a lot of social infrastructure like –employment generation, water security, healthcare benefits, improved education facilities etc.
Present Status of Hydro Projects in India
Total Hydro Potential
1,48,700 MW
Installed Hydro Capacity (As on 31.08.2018)
45,457 MW
Out of total 3,44,689 MW (13.18%)
6400 MW capacity stranded due to time/cost overrun, financial problems,
NGT etc
26, 460 MW DPRs cleared by CEA yet to be taken up for construction.
Most of these projects are pending due to want of Forest and
Environment clearances.
NHPC projects DPR cleared but yet to take off- 4995 MW
