METKA ATE is the business unit of the Greek company Mytilineos S.A., undertaking the construction of large-scale projects in the sectors of energy, infrastructure and defence.

In 1980 the company absorbed the technical contracting firm Technom S.A. thus acquiring the capacity to build and assemble items at an industrialized level and obtaining the ability to undertake and implement large-scale public works.

During the period of July 1998 through to January 1999, Mytilineos gradually acquired a controlling interest in the company and in early 1999 the acquisition was officially completed.

In 2012 Metka opens a Representation Office in Algeria and develops a series of energy projects, particularly with mobile power generating units, on a fast-track basis.

In 2016 Metka undertakes its second major project in Ghana, in consortium with General Electric, for the engineering, procurement, construction and commissioning of a 192MW combined cycle power plant in Takoradi.
