Consequently, grid operators increasingly combine these complementary technologies to enhance load flexibility and ensure reliable power delivery during periods of fluctuating renewable generation.
The rapid integration of renewable energy into electrical grids directly drives the demand for long-duration storage systems. Because wind and solar power generation fluctuate continuously, utility operators must efficiently capture excess electricity during peak production periods. According to the IEA, global renewable capacity additions reached nearly 510 Gigawatts in 2023. This rapid expansion of intermittent generation increases the need for robust storage infrastructure to maintain grid stability and balance power supply fluctuations. The IEA also reports that global wind and solar facilities generated over 3,900 Terawatt-hours of electricity in 2023. Consequently, grid operators increasingly deploy mechanical gravity storage systems to capture surplus renewable energy and ensure reliable electricity delivery.
Hydroelectric dams are the larger category, holding a market share of 85%, because these facilities utilise established, gravity-based reservoir systems to capture and provide dependable, large-scale electricity generation. Infrastructure developers favour this approach because it leverages massive bodies of water to store potential energy for extended durations. According to the IEA, global hydropower plants generated approximately 4,500 Terawatt-hours of electricity in 2024. Consequently, grid operators rely heavily on this extensive infrastructure to ensure a consistent power supply during peak demand.
Pumped hydro storage is the faster-growing category. Operators are increasingly deploying these systems to balance the fluctuating output of variable renewable energy sources by shifting surplus electricity to periods of peak demand through water transfer between elevation-separated reservoirs. According to the International Hydropower Association’s 2025 World Hydropower Outlook, 8.4 Gigawatts of new pumped storage capacity were commissioned globally in 2024, while the development pipeline now exceeds 600 Gigawatts. As power systems integrate higher shares of intermittent renewables, utilities are prioritising pumped storage as a reliable, long-duration solution to enhance grid stability and energy security.
