OUR HISTORY

Founded in May 1977, ENESA is one of Brazil’s largest electromechanical assembly and maintenance companies specialized in construction and assembly engineering solutions and EPC (Engineering, Procurement and Construction) activities for the most diverse sectors of the economy, especially large industrial and infrastructure works.

In 1978, just one year after it began operations, one of ENESA’s first projects was the iconic Itaipu, the second largest hydroelectric power plant in the world today, already proving its great expertise in the industrial assembly market.

ENESA specialized and consolidated itself in various segments from 1979 to 1989, such as energy, steel metallurgy, transportation and cement, with major works for renowned companies that contributed significantly to its growth.

Subsequently, ENESA went on to consolidate itself in blast furnaces, copper and aluminum mining, among others. Still in 2003, it was awarded ISO 9001 certification, the first of several quality, safety and sustainability certifications.

• 2008: We achieved the historic milestone of 20 million hours worked without accidents resulting in time off work, gaining great prominence in the national engineering scene in terms of safety;
• 2011: We carried out one of the largest readjustment projects in the mining industry;
• 2015: Start in the Pulp and Paper sector, the year in which we achieved the NBR 16001 Social Responsibility certification and, in addition to the ISO 14001 – Environmental Management System and OHSAS 18001 – Occupational Health and Safety Management System;
