ISASTUR, the holding company of the group, was founded in 1978 by a group of Asturian entrepreneurs and professionals. Over the years, the dedication of the professionals who, across multiple generations, have been part of our company, has fostered our growth and expansion in Spain and in several countries across Europe, Africa, and the Americas. What began as a nearly family-run business in the late 1970s is now a group of companies specializing in building infrastructures, primarily related to the energy sector, operating on five continents.
Years of effort, innovation, experience, and the trust placed in us by clients with highest standards have positioned ISASTUR companies as benchmarks in their respective fields. This success has been achieved through the high qualifications of our employees, the continuous updating of their work techniques and technical knowledge, and strict adherence to safety and quality standards. In short, we consistently place EXCELLENCE as the primary and shared objective in our jobs.
ISASTUR is organized into different companies according to the activities they perform:
The group has extensive experience in the electrical engineering sector. Among our key expertise are medium, high, and very high voltage projects: transformer substations for outdoor and indoor installations (GIS) up to 800 kV in AC and DC, civil works engineering, structural steel design, and protection and control as well as communication systems.
We also specialize in the design of renewable energy generation plants, from resource evaluation, design, permitting, basic and detailed engineering to construction management and supervision.
With over 20 years of experience in the renewable energy sector, ISASTUR has participated in the design and construction of PV power plants (with over 3,000 MW installed across various countries), wind farms (with over 2,500 MW installed), as well as solar thermal, biomass, and cogeneration plants.
Our international presence has enabled us to offer our clients turnkey construction projects worlwide.
Since the beginning of our activities, one of ISASTUR main areas has been the design, construction, and commissioning of high and very high voltage transformer substations, both indoor and outdoor, up to 800 kV, in all types and configurations (conventional, GIS, hybrid); as well as the construction of high voltage overhead and underground lines up to 400 kV.
Numerous companies across various sectors (electric, energy, steel, cement, etc.) rely on us for the electromechanical assembly and maintenance of their facilities or for the industrial automation of their systems. Our capabilities include mechanical and electrical erection, instrumentation, industrial automation, and maintenance.
Even before market and economic conditions made it necessary, ISASTUR had already focused part of its efforts on the internationalization of its activities. We were pioneers in expanding beyond Spain, and today ISASTUR has extensive experience in undertaking projects on an international scale.
Our international aim has allowed us to establish a permanent presence in countries across Europe, the Americas, and North Africa: United Kingdom, Italy, Argentina, Chile, Colombia, El Salvador, Guatemala, Mexico, Peru, Dominican Republic, Uruguay, Morocco, and Algeria. Besides having a stable presence in these countries, ISASTUR has also worked in others such as Germany, Belgium, France, Latvia, Lithuania, Norway, Netherlands, Romania, Jordan, Yemen, Qatar, Egypt, Angola, Bolivia, Ecuador, Venezuela, and Aruba.
Health and Safety, Quality, and Environment are fundamental elements for ISASTUR approach, integrated into our global management and based on mutual trust, communication, and the participation of everyone: executives, technicians, workers… and, of course, clients.
ISASTUR complies with all requirements and certifications in these areas, in addition to numerous awards for both performance and initiatives to promote Occupational Risk Prevention in a transversal way, both within our companies and in society in general.
ISASTUR has always been at the forefront of good business and commercial practices, upholding and demanding high standards of internal compliance that exceed mere regulatory requirements.
This effort has been reflected in obtaining UNE 19602:2019 and UNE 19601:2017 certifications, related to tax and legal compliance, respectively.
