Renewable Power International acquired by Cube Infrastructure

Renewable Power International (RPI) is an independent power producer headquartered in Madrid that focuses on renewable energy generation in the Iberian Peninsula. Established over 25 years ago, the company specializes in the development, construction, and operation of small‑hydro facilities, a niche that accounts for the majority of its installed capacity. RPI currently operates 17 mini‑hydro plants—ten in Spain and seven in Portugal—with a combined nameplate capacity of 85 MW. Each asset is held under long‑term concession contracts that provide an average remaining operational life of 28 years, ensuring stable electricity output and predictable cash flows. The company’s business model centers on acquiring water rights, securing grid connection permits, and managing turbine and civil infrastructure, while selling generated electricity under regulated tariffs and power purchase agreements. RPI’s customer base includes national transmission system operators and regional utilities that purchase the renewable output to meet statutory renewable targets. The firm’s portfolio is geographically diversified across the Spanish Atlantic coast, the Cantabrian basin, and Portuguese river systems, allowing exposure to varied hydrological conditions. RPI maintains an in‑house engineering team responsible for routine maintenance, performance optimisation, and compliance with environmental licences. The company also pursues pipeline development, targeting additional small‑hydro sites identified in the Iberian Renewable Energy Plans, which project an incremental 850 MW of capacity by 2020. Funding for new projects is sourced from equity partners and project‑level debt.
