Thus, pumped storage plants can operate only if these plants are interconnected in a large grid. The pumped storage plant is consists of two ponds, one at a high level and other at a low level with powerhouse near the low-level pond. The two ponds are connected through a penstock. The pumped storage plant is shown in fig. 1.
Pumped storage power plants are currently the most economical way of efficiently storing large amounts of energy over a longer period. As the most proven, reliable and cost-eficient technolo-gy for bulk energy storage, pumped storage hydropower is already a significant contributor to our clean energy future.
Pumped storage is the most widespread energy storage system in use on power networks. Its main applications are for energy management, frequency control, and provision of reserve. PHS is a mature technology with large volume, long storage period, high efficiency, and relatively low capital cost per unit of energy.
Pumped storage hydropower plants play a key role in the future of energy, contributing to grid stabilization, renewable energy storage and reduced dependence on fossil fuels. Together with BESS systems, renewable energy storage in pumped storage power plants will be a strategic ally for a resilient, secure and sustainable energy system.
In the event of a power outage, a pumped storage plant can reactivate the grid by harnessing the energy produced by sending "emergency" water – which is kept in the upper reservoir for this very purpose – through the turbines. Pumped storage hydropower plants fall into two categories:
Pumped stor-age can also be more than just a back-up for intermit-tent renewable energy resources and additional grid supporting services. Its inherent operational flexibility al-lows pumped storage to ofer a wide spectrum of benefits and it plays a vital role within local and regional water and energy programs.
