RESTRAINT

"Shrinking capacity additions and drought-driven volatility"

The global hydropower market faces slowing momentum, with 67 % decline in five-year average capacity additions in 2023 from 32 GW in 2022 to 13 GW. China, once responsible for half of new capacity, added only 530 MW. Extreme drought caused 5 % global generation dips, and Canada reversed a 30 % export surplus, moving to net importer due to reduced hydropower. These environmental stressors, combined with long permitting and infrastructure timelines, severely restrict near-term expansion and risk infrastructure resilience.

OPPORTUNITY

"Unlocking non-powered dams and leveraging pipeline capacity"

The United States alone has up to 12 GW technical potential via non-powered dams (over 54,000 dams). Globally, the hydropower pipeline exceeds 1,000 GW, offering 475 GW conventional and 600 GW pumped storage expansion opportunities. Repurposing existing dams, deploying modular pumped storage, and capitalizing on storage mandates provide scalable deployment paths. In the U.S., pumped storage development increased 43 % in projects over three years. Hydropower remains the largest renewable energy source, producing nearly 14.3 % of global electricity, presenting long-term B2B investment potential.

CHALLENGE

"High capital intensity and development complexity"

Hydropower projects especially pumped storage demand large infrastructure investment, with construction timelines extending multiple years and cost overruns common. Large dams displace millions: nearly 80 million people affected historically, elevating social and environmental complexity. Climate impacts such as drought reduce water inflows, jeopardizing capacity and export markets, as seen in Canada’s 30 % drop in exports. Regulatory timelines and permitting delays hinder project momentum, while financing is uncertain, especially outside state-financed markets. These factors combine to heighten risk and deter B2B investor confidence.
