An upgrade that adds 25 years to the plant life and boosts efficiency by 20%
Alstom has just shipped a new GT24 gas turbine to Mexico’s El Sauz combined cycle power plant. Alstom was awarded last year the contract worth approximately €40 million with Spain’s ACS Group to provide power equipment and services for the El Sauz combined cycle power plant in Queretaro, one of Mexico's most industrialized states.
Gas-fired El Sauz, which consists of three gas turbines and an 80 MW steam turbine, entered operation in 1981 and is owned and operated by Mexico’s state-owned utility, Comision Federal de Electricidad (CFE). Alstom has provided a new GT24 gas turbine to replace the existing gas turbines. This project will add at least 25 years to the power plant’s lifetime and boost its efficiency by 20%.
Launched in 1994, Alstom’s GT24 gas turbine has been continuously upgraded to incorporate the latest advances in gas turbine technology. Its unique sequential combustion engine emits less nitrous oxide (NOx) per megawatt (MW). The 2011 GT24 upgrade offers industry-leading operational flexibility, with the capability of producing in excess of 700MW in a 2-on-1 combined cycle configuration, achieving gross efficiency of more than 60% and a spinning reserve capability that can deliver 450MW in just 10 minutes. This spinning reserve capability makes the GT24 ideally suited for countering the intermittency of renewable energy sources like wind and solar.
