Madrid – Alantra has acted as exclusive M&A advisor to RIVE Private Investment, a European independent asset manager focused on energy transition and transportation assets, on its investment in REBI, a Spanish family-owned renewable energy infrastructure company that provides sustainable, carbon-neutral thermal energy solutions to industrial and residential customers.

The successful completion of this transaction reflects the growing relevance of thermal decarbonization infrastructure in Spain. It also highlights the importance of combining sector expertise, detailed market knowledge, and clear positioning in M&A processes in the current environment.”

This transaction further strengthens Alantra’s track record in Power Infrastructure M&A transactions, which includes advising Rolwind Renovables on the sale of one of Spain’s largest late-stage standalone battery storage portfolios to ENGIE, Iberdrola on the sale of a portfolio of hydro power plants in Spain to a platform participated by RPI and Cube, and Igneo Infrastructure Partners on its investment in the bioenergy platform ENSO.
