# ACCIONA — Sustainable infrastructure, renewable energy and complex project delivery

> ACCIONA is a Spanish infrastructure and renewable-energy group active across the development, design, construction, operation and maintenance of projects. Its businesses include renewable generation, transport, water and other essential infrastructure. The group has delivered projects through subsidiaries and consortia; the exact engineering, procurement and construction scope therefore varies by contract. Its ACCIONA Energía business reported 14,699 MW of installed renewable capacity at 30 June 2026, while group reporting keeps infrastructure, energy and other businesses distinct.
