Why in the News?
The Ministry of Coal is working on a plan to develop Pump Storage Projects(PSP) in de-coaled coal mines.
What are Pump Storage Projects(PSP)?
1. Pumped storage is a type of hydropower energy storage system used for grid energy storage.
2. It is a form of clean energy storage that is ideal for electricity grids reliant on solar and wind power.
3. This technology absorbs surplus energy at times of low demand and releases it when demand is high.
How do Pumped storage power plants work?
1. Pumped hydropower storage uses the force of gravity to generate electricity using water that has been previously pumped from a lower source to an upper reservoir.
2. The water is pumped to the higher reservoir at times of low demand.
3. At times of high demand, the water is then released to drive a turbine in a powerhouse and supply electricity to the grid.
Why is government planning to develop Pump Storage Projects(PSP) on de-coaled mines?
There are over 200 de-coaled mines with huge land area. Many of these mines are feasible for pumped storage power plants as lower reservoirs, head of water and land are available.
What are the advantages of Pump Storage Projects(PSP)?
| Specifications | Details |
| Grid Stability and Reliability | Provides a reliable and rapid response to changes in electricity demand. It can quickly generate electricity during peak demand periods, helping to stabilize the grid. |
| Long Lifespan and Durability | Pumped storage facilities typically have long lifespans and are built to withstand frequent cycling between pumping and generating modes. This makes them durable and reliable assets for energy infrastructure. |
| Water Management | These power plants can be designed to manage water resources effectively, ensuring responsible use and minimizing environmental impact. |
| Integration of Renewable Energy | Pumped storage helps integrate renewable energy sources into the grid by compensating for their intermittency. It provides a way to store excess energy when renewable sources are abundant and release it when they are not producing electricity. |
| Reduced Greenhouse Gas Emissions | By facilitating the efficient use of renewable energy and reducing the need for fossil fuel-based peaking power plants, pumped storage can contribute to a reduction in greenhouse gas emissions. |
