What is pumped hydro energy storage?

Pumped hydro energy storage constitutes 97% of the global capacity of stored power and over 99% of stored energy and is the leading method of energy storage. Off-river pumped hydro energy storage options, strong interconnections over large areas, and demand management can support a highly renewable electricity system at a modest cost.

How can energy storage support Indonesia's decarbonization agenda?

A key measure to support Indonesia’s decarbonization agenda is the development of energy storage to enable integration of renewable energy into the grid. Pumped storage hydropower plays a crucial role in this approach.

Why does Indonesia need a large amount of energy storage?

Because Indonesia has relatively small energy potential from hydro, wind, biomass, geothermal and ocean energy, it will rely mostly on solar for its sustainable energy needs. Thus, Indonesia will require large amounts of storage for overnight and longer periods. Pumped hydro comprises 99% of global energy storage for the electricity industry.

How many GWh pumped hydro energy storage sites in Indonesia?

Map data ©2021 Google. Potential 150 GWh Greenfield off-river pumped hydro energy storage sites in Indonesia (Source: , detailed zoomable map is available at NationalMap , Available onlne: .eng.anu.edu.au/ (accessed on 1 March 2022)).

Is pumped hydro energy storage a viable alternative to solar energy?

Pumped hydro comprises 99% of global energy storage for the electricity industry. In this paper, we demonstrate that Indonesia has vast practical potential for low-cost off-river pumped hydro energy storage with low environmental and social impact; far more than it needs to balance a solar-dominated energy system.

Does East Asia have pumped hydro energy?

East Asia has abundant wind, solar, and off-river pumped hydro energy resources. The identified pumped hydro energy storage potential is 100 times more than required to support 100% renewable energy in East Asia.
