What AESA does

AESA (legal entity AE, S.A.) is a Barcelona-headquartered energy consulting and engineering firm founded in 1981 that specializes in high-efficiency industrial energy solutions, with core practices in cogeneration, bioenergy, energy recovery, and industrial decarbonization. The firm operates four integrated service lines — Decarbonization strategy, Energy Assessment, Design & Engineering, and Operation Assistance — supported by a proprietary Python-based thermodynamic process simulation tool developed in-house under the AESIMPY project and used to evaluate emerging technologies such as gasification, hydrogen, high-temperature heat pumps, and concentrated solar power. AESA has delivered 164 reference installations totaling approximately 1365 MWe and 2100+ MWt of combined electrical and thermal capacity, serving energy-intensive industrial customers across automotive, food & beverage, paper, pharmaceuticals, chemicals, sugar, and energy-infrastructure sectors.

AESA serves primarily large enterprise and public-sector clients on a project-based B2B professional services model, with no public pricing or standardized tiers; engagements span feasibility studies, energy audits, due diligence, asset valuation, FEED and detail engineering, procurement management, construction supervision, commissioning, and operational monitoring, plus certified efficient-cogeneration accreditation through its Mexico subsidiary. The firm operates from Barcelona (HQ, Aragó 383), Mexico City (regional HQ in the World Trade Center), and Cartagena de Indias (Colombia), and extends its reach into Portugal through an exclusive Capstone microturbine distribution partnership with Micropower Europe. AESA holds minority equity stakes in three adjacent-technology firms (Micropower Europe, SIGE, and MSP Biogas), is founder-controlled under president José María Roqueta with CEO Raimon Argemí, and actively participates in multi-partner R&D consortia including COMECOCO2 (renewable methanol via CO2 electrolysis) and HYBCN (hydrogen). Certifications include ISO 9001 (Bureau Veritas), PYME Innovadora (Spanish Ministry of Science and Innovation, 2023), and accreditation as a cogeneration certifier in Mexico (2023).
