EFACEC Power Solutions SGPS, S.A. is a Portuguese energy, engineering and mobility company, comprising several subsidiaries in different international markets.

[citation needed] In 1958, the ACEC bought the CUF Group position, becoming the majority shareholder, a situation that remains after 1969, when Efacec were introducing into the stock exchange.

In September 2005, Manuel Gonçalves Textile and José de Mello launched a takeover bid on the Efacec capital, despite its actions still dispersed in stock exchanges.

[10] In 2007, with the support of its two shareholders (JMG and MGT), Efacec develops a new organizational model with ten business units: Transformers; High and Medium Voltage Switchgear; Energy Servicing; Engineering; Automation; Maintenance; Environment; Renewable; Transports and Logistics.

[18] This project will be developed alongside COMSA and MUNCK and, for Efacec, the value of this deal is approximately 47 million euros, which reflects the dimension and integration of the solutions offered by this company.

[19] Efacec already had experience in this business area, having been involved in the construction of subways in Bergen, Norway, Dublin, Ireland, and Porto, Portugal, being it that the European market corresponds to half its turnover.

The tender was launched by Trafikverket, the entity responsible for managing Sweden's railroad and road infrastructure, and it looked to the development, certification and supply of new generation automatic level crossing protection systems.

Following this international tender, Efacec, alongside a local partner, sealed the deal in a business with an estimated value of five million euros per year.
