POSCO participates at AES Gener´s Angamos Power Plant which Earned POWER´s Highest Honor

South Korea´s POSCO Engineering & Construction Co. Ltd. (POSCO) was the EPC contractor. Doosan Heavy Industries & Construction supplied the two coal – fired steam boilers outfitted with low-No, burners, and Italian manufacturer Ansaldo Energia provided steam turbines and the two 350-MVA air-cooled generators.
The AQCS (air quality control system), used was the first kind in South America and was designed to meet the latest emissions standards, published in Chile in June 2010.

POSCO received the notice to proceed for construction of the plant on April, 7, 2008.

Unit 1 entered commercial service in April 2011, approximately two weeks ahead of the schedule completion date. The second unit entered commercial service in October 2011.

POSCO completed both units early and earn $7 million schedule bonus. In addition unit performance tests found that the net output of both units was about 5% higher and the heat rate about 6% lower than the contract guarantee.

Angamos complies with all environmental standards promulgated by President Sebastian Piñera last February and meets requirements of Latin American and are at the same level of the European Union in terms of exigency.

Unique Design Feature

Fuel supply represented a special challenge because coal deliveries for Angamos are made by sea trough a dry bulk terminal that was constructed in Mejillones, north of Angamos Port. Although Angamos is located on the Pacific coast of northern Chile, it is situated in the 1,000 km-long Atacama Desert, the driest desert in the world.

The Angamos plant is the first of its kind in South America to use seawater cooling towers supplies from a seawater makeup pumping station, it also supplies seawater to the thermal vapor compression desalinization plants.Demineralized water is produced by a multiple-effect distillation system; this water system is cost-effective and sustainable for a plant.
