Report overview
Segments covered: type, technology, component, plant capacity, project type, application.
The growth of this market is mainly driven by the need for long-duration storage to integrate growing shares of wind and solar power, ambitious national targets and pipelines led by China and India, and policy support and market reforms in Europe, the U.K., and Australia. However, long lead times and permitting delays, high capital costs and cost overruns, geographic and environmental constraints, and competition from rapidly falling battery storage costs restrain the growth of this market.
Furthermore, closed-loop and off-river projects, modernization and variable-speed upgrades of existing plants, and projects using former mines and hybrid renewable sites are expected to offer growth opportunities for the stakeholders in this market. However, inadequate revenue models and market design, financing very long-lived assets, supply chain and skilled labor constraints, and water availability and climate risks remain major challenges impacting the growth of this market. Additionally, the scale-up of pumped storage in China, the adoption of variable-speed technology, the use of unconventional sites, and long-duration storage procurement mechanisms are prominent trends in this market.
The Pumped Hydro Storage Market comprises facilities that store energy by pumping water from a lower reservoir to an upper reservoir when electricity is abundant and releasing it through turbines to generate electricity when it is needed, together with the equipment, construction, and services involved in building, operating, and upgrading them. The market covers open-loop projects connected to rivers, closed-loop projects with off-river reservoirs, underground and mine-based projects, and seawater pumped storage; fixed-speed, variable-speed, and ternary technologies; and components including reversible pump-turbines, motor-generators, civil works, reservoirs, tunnels, penstocks, balance of plant, controls, and operation, maintenance, and modernization services. Market value reflects annual investment in new projects and in the modernization and uprating of existing plants. Conventional hydropower without pumping capability and other energy storage technologies are excluded. The ecosystem spans utilities and developers, equipment manufacturers, civil engineering and construction firms, grid operators, regulators, and financiers.
Pumped storage is the world's largest form of long-duration energy storage and is accelerating after years of slow growth. The International Hydropower Association reported in its 2025 World Hydropower Outlook that 8.4 gigawatts of pumped storage were added globally in 2024, a 5% increase to 189 gigawatts, and that annual additions have nearly doubled in two years, raising the five-year average to 6 gigawatts per year from 2 to 4 gigawatts over the previous two decades. The global hydropower development pipeline exceeded 1,075 gigawatts at the end of 2024, including about 600 gigawatts of pumped storage, and the IHA noted that pumped storage exceeds conventional hydropower by 88 gigawatts at the approved stage, indicating that pumped storage is expected to lead new hydropower capacity beyond 2030.
China dominates development, adding 14.4 gigawatts of hydropower in 2024, including 7.75 gigawatts of pumped storage, and is on track to exceed its target of 120 gigawatts of pumped storage by 2030, according to the IHA. India had about 44.5 gigawatts of pumped storage projects in development in early 2025 and aims to add 51 gigawatts by 2032, while Europe has a pipeline of 52.9 gigawatts in development, of which 3 gigawatts are under construction and 6.7 gigawatts have received regulatory approval. Australia is building Snowy 2.0, a 2.2-gigawatt project whose estimated cost rose to about AUD 12 billion, and the U.K. has introduced a cap-and-floor revenue mechanism for long-duration storage.
Despite this momentum, the IHA warned of a potential hydropower shortfall of 60 to 70 gigawatts by 2030 against the International Renewable Energy Agency's tripling renewables scenario, with IHA President Malcolm Turnbull stating that markets alone will not deliver and calling for bold policy action, reforms to reward hydropower's multiple benefits, and faster permitting. Pumped storage projects face long development timelines, high upfront costs, site constraints, and growing competition from battery storage, whose costs have fallen sharply, while offering advantages in duration, lifespan of many decades, and grid stability services.
Market dynamics
18 factors across 5 forcesNeed for Long-Duration Storage to Integrate Renewables
The need for long-duration storage to integrate growing shares of wind and solar power is a major factor driving the Pumped Hydro Storage Market. As variable renewable generation grows, power systems need to store surplus electricity for many hours or days and provide inertia, frequency control, and voltage support, services that pumped storage has provided for decades. The International Hydropower Association reported that global pumped storage capacity rose by 8.4 gigawatts in 2024 to 189 gigawatts and that annual additions have nearly doubled in two years, raising the five-year average to 6 gigawatts per year, compared with 2 to 4 gigawatts per year over the previous two decades. Pumped storage plants typically provide 6 to more than 20 hours of storage at full output, operate for many decades, and achieve round-trip efficiencies of around 70% to 85%, making them well suited to long-duration needs that are costly to meet with shorter-duration batteries.
National Targets and Pipelines Led by China and India
Ambitious national targets and pipelines, led by China and India, are significantly expanding the market. China added 7.75 gigawatts of pumped storage in 2024, more than half of its 14.4 gigawatts of new hydropower capacity, and is on track to exceed its 120-gigawatt pumped storage target for 2030, according to the International Hydropower Association. India had about 44.5 gigawatts of pumped storage projects at various stages of development in early 2025 and aims to add 51 gigawatts of pumped storage by 2032 to support its renewable energy expansion. The global pumped storage development pipeline of about 600 gigawatts, together with pumped storage exceeding conventional hydropower by 88 gigawatts at the approved stage, indicates sustained investment through the forecast period.
Policy Support and Market Reforms
Policy support and market reforms in Europe, the U.K., Australia, and the U.S. are creating clearer business cases for pumped storage. The IHA reported that EU and national policy measures are driving momentum for pumped storage in Europe, where a 52.9-gigawatt pipeline is in development, with 3 gigawatts under construction and 6.7 gigawatts approved. The U.K. has introduced a cap-and-floor regime for long-duration electricity storage, providing a revenue floor and cap to support investment in large projects, Australia is building Snowy 2.0 and supporting storage through capacity investment schemes, and in the U.S., the Inflation Reduction Act extended investment tax credits to energy storage, including pumped storage. Such mechanisms are essential given the IHA's view that markets alone will not deliver the capacity needed.
