What is the global pumped storage hydropower industry?

In 2023, pumped hydropower was the dominant global electricity storage solution, accounting for 62 percent of the world’s energy storage capacity. Discover all statistics and data on Global pumped storage hydropower industry now on statista.com!

What is pumped storage hydropower?

Pumped storage hydropower is an energy storage technology that plays a crucial role in stabilizing power grids, balancing electricity supply and demand, and integrating renewable energy sources into national grids.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.

How many new hydropower projects are there?

Hydropower capacity increased by net of 431 MW since the publication of the last Hydropower Market Report (2017–2019), and a net total of 1,688 MW from 2010 to 2019. 21 new projects (115 MW). The new projects consisted of two new stream- reach development (NSD) projects, 15 conduit projects and powering of four non-powered dams (NPDs).

How much electricity can a hydropower plant store?

The reservoirs of all existing conventional hydropower plants combined can store a total of 1 500 terawatt-hours (TWh) of electrical energy in one full cycle – the equivalent of almost half of the European Union’s current annual electricity demand.

What is the share of hydropower in global electricity generation?

At the global scale, the share of hydropower in total electricity generation has remained relatively flat at around 16% for the past 15 years. However, with the recent expansion of wind and solar PV installations, its share in global renewables-based electricity generation fell from 92% in 2005 to 61% in 2020. IEA. All rights reserved.
