Cover story


AESA – Energy assessment: CHP, bioenergy, zero emissions and energy efficiency

From 1982 to date, AESA has been specialising in what has become its primary mission: the search for and development of high efficiency energy solutions for their clients especially in the fields of CHP, bioenergy and energy recovery. The results of this work are 156 installations of reference as of today that add up to around 1,275 MWe and over 3,000 MWt.


As a multidisciplinary company, AESA benefits from expert professionals with extensive knowledge of the energy markets in which they work (Europe and Latin America), with engineers specialising in energy processes and in every other speciality required to fully implement these projects: process, mechanical, civil, electrical and control. Similarly, the company benefits from expert engineers in the commissioning and operation of power plants.

With offices in Barcelona (head office), Mexico City and Cartagena de Indias, AESA has undertaken projects in Spain, Portugal, Mexico, Colombia, the Dominican Republic, Argentina and Ecuador, as well as having provided consultancy services in France, Tunisia, Peru and Chile.

Studies and Energy Projects

AESA undertakes projects involving CHP, bioenergy, DHC networks, energy efficiency and the mitigation of CO2 emissions (capture, methanation…). It provides services in every project phase: initial feasibility studies, basic and detail engineering, project management, commissioning, installations’ operation and management.

Energy consultancy

All types of studies within the energy sector: potential analysis, generation costs, regulatory analysis and proposals, specific feasibility and energy efficiency studies, software development, audits, due diligence, asset valuation, technical opinions, assessment for the optimised operation of power plants, performance testing, training courses, certification of efficient CHP plants (Mexico), etc.

Engineering and project management

In the more than 150 projects undertaken, which together amount to 1,275 MW, AESA has used every type of technology, process and fuel, always seeking to ensure that the solution is the most effective and efficient for their client. AESA covers every project stage, providing the client with support until fully concluded and the plant is commissioned as well as offering the possibility of performing the projects in an EPC format.

Zero emissions projects

CO2 capture, electrolysis, methanation and power-to-X in general constitute one more step that enables the future development of the new CHP. AESA offers knowledge, experience and resources for the study and application of these technologies that will, very soon, form an essential part of any energy project…
