The Power Purchase Agreement (PPA) length for small hydro energy in the UK remained steady at 24 years from 2023 through 2025, with a slight increase to 25 years in 2026 and 2027, and reaching 26 years by 2028. This reflects a stable market environment with moderate growth.
Future trends to watch for include regulatory changes, technological advancements that could impact the cost and efficiency of small hydro projects, and shifts in investor appetites. These factors could influence both the length and terms of future PPAs in the sector.
