Source- This post on Pumped Storage Projects (PSPs) is based on the article “Government’s Commitment to Renewable Energy Gets a Significant Boost: CEA concurred two more Hydro Pumped Storage Projects (2500 MW)” published in PIB on 23rd September 2024.
Why in News?
Recently, CEA has approved two additional Pumped Storage Projects (PSPs) in Maharashtra: the 1500 MW Bhavali PSP and the 1000 MW Bhivpuri PSP. This has been done as part of its commitment to a sustainable energy future.
About Pumped Storage Projects (PSPs)
1. Pumped Storage Projects (PSPs)- Pumped Storage Projects (PSPs) play a crucial role in India’s transition to a renewable energy future. These projects function as large-scale energy storage systems, utilizing the gravitational potential energy of water.
2. Functioning of PSPs- During periods of low electricity demand, surplus power (usually from renewable sources) is used to pump water from a lower reservoir to a higher one. When electricity demand peaks, the stored water is released, flowing back down through turbines to generate electricity.
3. Significance of PSPs- This system helps in balancing the grid, ensuring stability during periods of high demand, and supporting the integration of renewable energy.
About the recently concurred Pumped Storage Projects
1. Two recently concurred Pumped Storage Projects in Maharashtra are the 1500 MW Bhavali PSP by JSW Energy Ltd. and the 1000 MW Bhivpuri PSP by Tata Power Co. Ltd. These are part of India’s growing focus on energy storage.
2. These projects are expected to be completed by 2028, will provide a combined storage capacity of over 15 GWh, offering significant support for grid stability during non-solar hours.
3. In addition to these, India has been developing several other pumped storage projects to meet its energy demands. Some notable ones include:
1. Srisailam Dam PSP: It is located on the Krishna River, Andhra Pradesh. This is one of the largest PSPs in India, with a capacity of 1,670 MW. It has been critical in providing power during peak hours.
2. Kadana Dam PSP: It is situated in Gujarat. This project has a capacity of 240 MW and contributes to balancing the energy supply during off-peak and peak periods.
3. Purulia Pumped Storage Project: It is located in West Bengal. This PSP has a capacity of 900 MW and is an important asset for managing energy during peak demand.
4. Tehri PSP: It is located in Uttarakhand. This PSP has a capacity of 1,000 MW and plays a vital role in regulating energy in the northern grid.
5. Pancheshwar Dam PSP: It is planned on the Mahakali River between India and Nepal. This large-scale project is expected to have a significant storage capacity to support renewable energy integration in the region.
