Perfect water treatment in just 25 weeks

Construction of a new 900 MW power station places tough demands on everyone involved. It's good to be able to rely on a supplier like ProMinent, who easily meets the demanding requirements thanks to in-house production.

900 MW plant for Pesquería

The small town of Pesquería is situated in north-east Mexico around 100 kilometres from the border with Texas. Construction of one of Mexico's largest combined gas and steam power stations started here in early 2014. From 2017 onwards, three gas turbines and one steam turbine are to provide steel plants belonging to the customer Techint with around 900 megawatts of power. In order to meet the planned completion date, Techint needed 17 metering systems to treat huge quantities of raw, process and cooling water at extremely short notice. The systems had to meet the high quality standards of the Mexican authorities and be available in just 25 weeks. Many providers were simply not able to achieve this – but ProMinent could.
