Hydropower generation is the production of electricity by using flowing or falling water to drive turbines connected to generators. It is a renewable energy source that can provide reliable electricity with relatively low operational emissions. Hydropower is widely used in large dams, run-of-river plants, and pumped-storage facilities, supporting grid stability and renewable energy integration.

Growing Role of Hydropower in Grid Flexibility and Energy Security
Hydropower is increasingly being valued not only for renewable electricity generation but also for its ability to provide dispatchable power, balancing services, and system flexibility. Reservoir and pumped-storage facilities can respond to changes in electricity demand and help grids accommodate increasing shares of variable solar and wind generation.
Increasing Investment in Pumped-Storage Hydropower
Pumped-storage hydropower is gaining importance as a long-duration energy-storage technology for electricity systems with growing renewable penetration. Its ability to store electricity and release it when needed positions it as a complementary technology to intermittent renewable generation and conventional battery storage.
Rising Electricity Demand and Expansion of Renewable Power Support Hydropower Development
Growing electricity consumption from industrial activity, electrification, digital infrastructure, and data centers is increasing the need for reliable low-carbon electricity. Hydropower can provide firm renewable generation while also balancing variable renewable sources, strengthening its role in electricity-system expansion.
High Capital Requirements and Long Project Development Periods Limit New Capacity
Large hydropower projects require substantial upfront investment and typically involve lengthy planning, permitting, construction, and environmental-assessment processes. These requirements can increase project risks and delay commissioning, particularly where financing conditions and regulatory approvals are uncertain.
Modernization of Aging Hydropower Plants Creates Expansion Opportunities
Modernizing existing hydropower facilities provides an opportunity to increase generation efficiency, extend plant operating life, improve reliability, and add greater grid-flexibility capabilities without relying entirely on new large-scale projects. Replacement of aging turbines and generators is becoming particularly important across mature hydropower markets.
Climate Variability and Extreme Weather Threaten Hydropower Reliability
Hydropower generation depends directly on water availability, making plants vulnerable to droughts, changing rainfall patterns, floods, landslides, and shifting seasonal river flows. Climate-related changes can reduce generation during periods of low water availability while extreme weather can damage infrastructure and disrupt plant operations.
Large Hydro Power Plant Segment Dominated the Market with 59% Share in 2025
The large hydro power plant segment dominated the hydropower generation market with a 59% share in 2025, reaching USD 153.02 billion, and is projected to grow at a CAGR of 4.8% during 2026–2034. Small hydro power plants accounted for a 22.4% share, reaching USD 58.10 billion, and are projected to grow at a CAGR of 5.8%, while medium hydro power plants represented an 18.6% share, reaching USD 48.24 billion, with a CAGR of 6.0%.
Large hydro power plants continue to hold the leading position because of their ability to generate electricity at a large scale and support grid reliability. Small and medium plants are also gaining attention as countries expand decentralized renewable generation and develop hydropower projects in areas with suitable local water resources.
