G-advisory turns 25

25 years, 25 steps that paved the way

G-advisory turns 25. Since its creation in the year 2000 under the name Garrigues Medio Ambiente, the technical, economic and strategic consulting arm of the Garrigues group has been a benchmark in the energy and sustainability industry. Throughout this time, G-advisory has developed over 3,000 projects in over 40 countries in 5 continents for the private sector, the public authorities, industry associations and multilateral organizations, among others.

Hand-in-hand with the firm, G-advisory offers a service that sets us apart, with an integral approach that combines technical, economic and strategic aspects, thanks to a cohesive team comprised of professionals with different profiles. 360º advice covering all types of energy, with a focus on electricity generation: wind, photovoltaic, CSP, biomass, biogas, large and small hydropower, cogeneration and waste-to-energy technologies, storage, transfer and distribution of electricity and gases and renewable fuels.

It also works alongside clients in a wide range of services in connection with ESG: due diligence ESG, waste management and treatment, the integrated water cycle and decarbonization. In 2013 it changed its name to G-advisory, strengthening the firm’s identity and way of working. Since then, the firm has consolidated a culture based on excellence, collaboration, technical rigor and the constant search for innovative solutions that add real value to its clients’ projects.

These 25 years are also the history of a team that has grown and changed together with the industry, combining experience and young talent to anticipate market trends and the challenges of the energy transition. It has been 25 years, 25 steps that paved the way, a journey built with dedication, commitment and a shared vision: to provide help in the move towards a more sustainable energy and economic model.

With the next few years in mind, G-advisory reaffirms its commitment to excellence, innovation and sustainability, continuing its work as a strategic ally to those who pursue a more efficient and competitive future that respects the environment. Because each step that has been taken in these last 25 years is the motivation for those still to come.
