With an expanding client base across the energy industry, Sainz Abogados has reinforced its capabilities in project development, transactional work, and regulatory compliance, with experience spanning oil-and-gas, electric power and renewables. The group is well-versed in navigating complex regulatory frameworks to secure project authorisations and is also adept in dispute resolution, having represented key clients such as CFEnergía in both litigation and arbitration procedures. Francisco Valdés López, a recognised figure with two decades’ experience in the energy space, co-leads the practice alongside Diana Pineda, a highly regarded specialist, active in multijurisdictional project structuring and administrative litigation involving energy regulation. Counsel Pedro Lladó is another notable figure who advises on large infrastructure projects.
