Central Costanera S.A. is an Argentina-based electric power generation company engaged in the production and commercialization of thermoelectric energy. The company operates the Costanera thermal power plant complex situated in the Autonomous City of Buenos Aires, which ranks among the largest thermal generation facilities in Argentina with an aggregate installed nominal capacity exceeding 2,300 megawatts. Central Costanera generates electricity utilizing multi-fuel thermal technologies, including conventional steam turbine generation units powered by natural gas, fuel oil, and gas oil; and combined-cycle gas turbine (CCGT) configurations comprising gas turbines, heat recovery steam generators, and steam turbines. Its principal product and service offerings comprise wholesale electric power generation supplied to the Argentine Interconnection System (SADI); dispatchable base-load and peak-load electric energy capacity; grid stability and frequency regulation ancillary services; dual-fuel thermal generation capabilities ensuring dispatch continuity across variable fuel supply conditions; and operational management and maintenance of heavy-duty power generation assets. The company delivers its electrical output to the Argentine Wholesale Electricity Market (MEM) under regulatory frameworks administered by the Compañía Administradora del Mercado Mayorista Eléctrico S.A. (CAMMESA), ultimately supplying regional electricity distribution utilities, large industrial consumers, and commercial entities across the Greater Buenos Aires metropolitan area and the national territory.
Founded in 1992 following the restructuring and privatization of Servicios Eléctricos del Gran Buenos Aires (SEGBA), Central Costanera S.A. is headquartered in Buenos Aires, Argentina. In recent major corporate and strategic developments, Italian energy group Enel completed the sale of its 75.7% controlling equity stake in Central Costanera S.A. to Central Puerto S.A., one of the country's leading power generation holding companies. Following this change of control, the company has been integrated into Central Puerto's consolidated generation portfolio, realizing operational synergies across fuel logistics, fleet maintenance, and administrative management. Recent operational initiatives include comprehensive maintenance and overhaul programs across its steam and combined-cycle turbine blocks to improve plant heat rates, enhance equipment availability and reliability, optimize dual-fuel firing flexibility, and adapt to updated remuneration and dispatch frameworks enacted by Argentina's energy authorities.
