According to Fortune Business Insights, the global hydropower market size was valued at USD 116.09 billion in 2025. The market is projected to grow from USD 123.68 billion in 2026 to USD 202.46 billion by 2034, exhibiting a compound annual growth rate (CAGR) of 6.35% during the forecast period. Asia Pacific dominated the global market, accounting for 59.54% of the market share in 2025.
Hydropower, also known as hydroelectric power, generates electricity by utilizing the energy of flowing or falling water. It is an important renewable energy source that supports electricity generation, grid stability, and energy security. Hydropower facilities include large dams, run-of-river plants, and small-scale installations designed to meet different electricity requirements.
The market is expanding as governments and utilities invest in renewable energy infrastructure, modernize existing power plants, and seek reliable low-carbon electricity generation. Increasing electricity demand and the integration of solar and wind energy are further strengthening the importance of hydropower.
Market Growth Drivers
Increasing Demand for Renewable Electricity
The growing demand for clean electricity is a major factor driving the hydropower market. Governments worldwide are implementing renewable energy strategies to reduce greenhouse gas emissions and diversify electricity generation.
Hydropower provides electricity without directly burning fossil fuels during operation. Its ability to generate substantial amounts of electricity makes it an important component of renewable energy portfolios. Countries with suitable water resources are investing in new facilities and upgrading existing plants to improve generation capacity and operational efficiency.

Growing Need for Grid Stability
Hydropower plants can adjust electricity generation according to changes in demand, making them valuable for maintaining grid stability. This flexibility is particularly important as electricity networks incorporate increasing amounts of intermittent solar and wind power.
Pumped-storage hydropower provides an additional advantage by storing energy. These systems pump water to an elevated reservoir when electricity is available and release it through turbines when demand increases. This capability supports energy storage and improves the reliability of electricity networks.
Government Investments and Supportive Policies
Government funding, renewable energy targets, and infrastructure development programs are encouraging hydropower investments. Public-sector support helps finance large projects, improve existing facilities, and develop electricity transmission networks.
International electricity trade is also creating opportunities. Countries with substantial hydropower resources can export surplus electricity to neighboring markets, generating revenue and supporting regional energy cooperation.
Key Market Trends
Expansion of Pumped-Storage Hydropower
Pumped-storage hydropower is becoming increasingly important as utilities seek large-scale energy storage solutions. These facilities can store substantial amounts of electricity and provide power during periods of peak demand.
Their ability to balance fluctuations in renewable electricity generation makes them valuable for modern power systems. Investments in pumped-storage infrastructure are expected to support hydropower market development.
Modernization of Existing Hydropower Plants
Operators are upgrading aging hydropower facilities to improve efficiency, reliability, and electricity output. Modern turbines, digital monitoring systems, automation, and predictive maintenance technologies can improve plant performance.
Modernization may also increase the capacity of existing facilities without requiring entirely new dams. These improvements can help utilities meet growing electricity demand while making better use of established infrastructure.
Development of Small Hydropower Projects
Small hydropower installations are attracting interest because they can supply electricity to rural communities, remote industrial facilities, and locations with limited grid access.
These projects can be developed along suitable rivers, streams, and irrigation channels. Compared with large projects, some small installations may require less extensive infrastructure, although environmental impacts and project economics depend on local conditions.
Market Segmentation Analysis
By Type
Based on type, the market is segmented into small hydropower and large hydropower. The large hydropower segment dominated the market, accounting for 56.96% of the market share in 2024.
Large hydropower facilities generate substantial electricity and support national power grids. Government investments, infrastructure development, and rising electricity demand are contributing to segment growth.
Small hydropower projects also offer opportunities, particularly in rural electrification and decentralized energy generation. Their adoption depends on water availability, project costs, and environmental requirements.
