What G-advisory does
G-advisory is the technical, economic, and strategic consulting arm of the Garrigues Group, founded in 2000 in Madrid under the name Garrigues Medio Ambiente and rebranded to its current identity. The firm specializes in energy and ESG advisory, providing 360-degree coverage of energy technologies including wind, photovoltaic, concentrated solar power (CSP), biomass, biogas, hydropower, cogeneration, and waste-to-energy. Over 25 years, G-advisory has delivered more than 2,700 projects across 40+ countries on five continents, serving renewable energy developers, utilities, financial institutions, public administrations, industry associations, and multilateral organizations. The firm recently marked its 25th anniversary in April 2026 alongside the opening of a new Bogotá office to deepen its Latin American presence.
The company operates two core service lines: Energy Consulting Services (technical and commercial due diligence for M&A and project finance transactions, market studies, regulatory analysis, pool price projections, PPA negotiation support, and commercial advisory) and Sustainability & ESG Services (design and implementation of ESG compliance systems, sustainability strategy, green financing advisory, climate change services, waste and water treatment advisory). The offering is technology-agnostic — G-advisory produces bespoke human-delivered analytical deliverables rather than software or platform products. Its competitive positioning derives from the multidisciplinary integration of legal expertise (via Garrigues), technical engineering, and economic analysis on the same transactions, including large cross-border financings in Spain, Mexico, Chile, Peru, Uruguay, and El Salvador.
G-advisory generates revenue through quote-based professional services fees tied to specific project proposals and engagement letters, with multi-year contracts typical for larger advisory mandates. Pricing is not publicly disclosed and the firm does not sell services through its web portal — distribution is exclusively through direct B2B enterprise sales leveraging the Garrigues brand, referral network, and repeat lender relationships. Geographic coverage spans 15+ cities including Madrid (headquarters), Bogotá, Mexico City, Santiago de Chile, Lima, New York, London, Warsaw, Brussels, Lisbon, Oporto, Casablanca, Shanghai, Monterrey, and Querétaro. The firm is a wholly-owned subsidiary of the Garrigues Group with no external investment or public listing.
