India’s power sector has been witnessing a large share of renewable energy (RE) being integrated into the grid. This is expected to grow at a high pace in the future as well. With increasing RE share, storage, especially pumped-hydro energy storage (PHES), plays a key role in dispatching the energy from RE resources, peak load shaving, frequency regulation, voltage support, providing round-the-clock support, and balancing the grid, among others. Over the years, PHES has been one of the leading bulk energy storage options worldwide due to its ability to provide support in grid handling.
This blog post provides an overview of PHES in the Indian context, detailing the current status and prospects for future development.
