Overview
Metka ATE was a Greek engineering, procurement and construction business that developed and delivered large-scale projects in energy, infrastructure and defence. Its core activity was the engineering, procurement, construction and commissioning of power-generation facilities, particularly high-efficiency combined-cycle gas-turbine plants. The company also operated substantial industrial manufacturing facilities in Volos, where it produced fabricated steelwork, mechanical equipment, machinery and other specialized components for industrial and defence applications. The business originated in 1962, when the Hellenic Industrial Development Bank established it in Volos, a major industrial and port city in central Greece. Its manufacturing plant began operating in 1964 and initially concentrated on large metal constructions and complex mechanical projects. Metka expanded from manufacturing into project contracting through privatization in 1971, a 1973 Athens Exchange listing and subsequent acquisitions. These developments gave it the capacity to undertake increasingly complex public works and international projects. Two acquisitions were particularly important to its industrial development. In 1980, Metka absorbed the technical contracting company Technom S.A., adding industrialized construction and assembly capabilities for major public works. In 1989, it acquired the Hellenic Steel Process Industry, also known as Servisteel. Servisteel brought automated blasting, cutting and drilling equipment that enabled Metka to industrialize more of its metalworking operations. Over time, the company broadened its activities into energy, defence, renewable energy, exports and refinery-related work. Mytilineos gradually acquired a controlling stake between July 1998 and January 1999, completing the acquisition in early 1999. Metka subsequently expanded its project and engineering platform through investments and affiliated businesses, including a 40% interest in EKME in 1999 and the acquisition of civil-engineering specialist Elemka in 2006. Its internationalization accelerated during the following decade, with a Turkish subsidiary, a representation office in Algeria and a later office in Ghana. These operations supported projects across the Middle East and Africa, where demand for power infrastructure was a major growth opportunity. The company also pursued renewable and decentralized-energy opportunities. In 2015 it established Metka EGN through a joint venture with Egnatia Group to strengthen its position in solar power. In 2016, Metka EGN secured solar and hybrid-power EPC contracts with an aggregate capacity of 75 MW, while Metka entered a strategic partnership with International Power Supply for off-grid power systems based on the EXERON modular power-conversion platform. The same year, Metka worked with General Electric on the engineering, procurement, construction and commissioning of a 192 MW combined-cycle power plant at Takoradi in Ghana. Metka's corporate identity as a standalone listed company ended after the 2017 announcement of the merger of Mytilineos Holdings with its principal subsidiaries, including Metka, Protergia and Aluminium of Greece. The former business therefore survives primarily as a business unit, capability set or operating brand within the broader Mytilineos organization rather than as an independent listed company. Its historical profile combines heavy industrial manufacturing with international EPC contracting, especially for power-generation projects.
History
Metka was founded in 1962 by the Hellenic Industrial Development Bank in Volos, Greece. A metal-construction manufacturing plant began operations in 1964, initially producing large and technically complex metal and mechanical structures. The company was privatized in 1971 and listed on the Athens Exchange in 1973. Its subsequent acquisitions broadened its capabilities and helped it move from industrial manufacturing into large-scale contracting and international project delivery. In 1980, Metka absorbed Technom S.A., a technical contracting company. This added industrialized construction and assembly capabilities and strengthened Metka's ability to execute major public-works projects. In 1989, it acquired Servisteel, the Hellenic Steel Process Industry. Servisteel's automated equipment for blasting, cutting and drilling enabled more systematic and industrialized processing of metalwork. During this phase, Metka expanded its scope beyond traditional fabrication into energy, defence, renewable energy, exports and refinery-related projects. Mytilineos gradually acquired a controlling interest in Metka between July 1998 and January 1999. The acquisition was completed in early 1999. Later that year, Metka acquired a 40% interest in EKME, a company involved in designing and constructing units for petrochemical and power-production facilities. In 2006, Metka acquired Elemka, which specialized in civil-engineering applications. These transactions created a broader platform spanning industrial manufacturing, civil works, plant engineering and EPC contracting. Metka strengthened its international reach during the 2000s and 2010s. It established Power Projects Limited in Turkey in 2009 and opened a representation office in Algeria in 2012. The Algerian operation supported energy projects, including fast-track mobile power-generation installations. In 2015, Metka opened a representation office in Ghana, reflecting a strategic emphasis on African markets with expanding electricity demand. Renewable and distributed-energy activities became more prominent during the same period. Metka EGN was established in 2015 through a joint venture with Egnatia Group to develop the company's solar-power portfolio. In 2016, Metka EGN secured solar and hybrid-power EPC contracts totaling 75 MW. Metka also formed a strategic partnership with International Power Supply, a manufacturer of the EXERON modular power-conversion system, to address off-grid power applications. Metka's conventional power business remained central. In Ghana, it undertook a second major project in 2016 through a consortium with General Electric. The project involved engineering, procurement, construction and commissioning of a 192 MW combined-cycle power plant in Takoradi. The project illustrated Metka's combination of large-project management, power-plant engineering and international consortium work. The business's main offices were in Athens, while its industrial facilities remained in Volos. Its activities served customers in Greece and international markets, particularly Europe, the Middle East and Africa. In 2017, Mytilineos Holdings announced its merger with principal subsidiaries including Metka, Protergia and Aluminium of Greece. Following that corporate restructuring, Metka ceased to operate as an independent listed company, although its EPC and industrial capabilities continued within the Mytilineos group structure.
