What is pumped storage hydropower?

Pumped storage hydropower is the world's largest battery technology, with a global installed capacity of nearly 200 GW – this accounts for over 94% of the world’s long duration energy storage capacity, well ahead of lithium-ion and other battery types. Water in a PSH system can be reused multiple times, making it a rechargeable water battery.

What is a pumped storage plant?

Built by Spanish company Iberdrola at a cost of €1.5bn, the facility in a rocky river valley in northern Portugal is known as a pumped storage plant. But insiders have another name for the reservoir at the top of the mountain. It is a “water battery” — rudimentary in concept, intricately engineered and a highly effective way of storing energy.

How much energy is stored in pumped storage reservoirs?

A bottom up analysis of energy stored in the world’s pumped storage reservoirs using IHA’s stations database estimates total storage to be up to 9,000 GWh. PSH operations and technology are adapting to the changing power system requirements incurred by variable renewable energy (VRE) sources.

Is pumped storage hydropower the world's water battery?

Below are some of the paper's key messages and findings. Pumped storage hydropower (PSH), 'the world’s water battery’, accounts for over 94% of installed global energy storage capacity, and retains several advantages such as lifetime cost, levels of sustainability and scale.
