Hydropower Market Size to Grow from 1.5 TW in 2026 to 1.67 TW by 2031, Driven by Pumped-Storage and Small Hydro Expansion

The global hydropower market continues to play a critical role in supporting low-carbon energy systems worldwide. Estimated at 1.5 terawatt in 2026, the hydropower industry is projected to reach 1.67 terawatt by 2031, reflecting steady Hydropower Market Growth. Modernization of existing plants, combined with new small and micro-hydro installations, is creating flexible and reliable power capacity for utilities, industrial users, and independent power producers. As governments push for climate-resilient energy solutions, hydropower is increasingly recognized as both a renewable energy source and a climate-adaptive infrastructure. 

Key Hydropower Market Growth Trends  

• Surge in pumped-storage retrofits of existing dams to act as grid-scale batteries. 
• Adoption of digital twins and predictive maintenance to extend plant lifetimes and optimize operations. 
• Increasing hybrid hydro-solar plants using grid-forming inverters for stable and efficient energy supply. 
• Small and micro-hydro projects expanding decentralized electrification, especially in rural areas. 
• Corporate power-purchase agreements driving investment in baseload renewable capacity.
