Alstom has received contracts to supply a power island (KA24) for Iberdrola's Monterrey III combined-cycle power plant in Pesqueria, Nuevo Leon, Mexico.
Under the €335m ($450m) contract, Alstom will supply major equipment and maintenance package for Iberdrola's Monterrey III power plant.
The contract also includes a long-term service agreement (LTSA) for new unit five and for the existing four units.
The new unit, scheduled to be commissioned in 2016, comprises one GT24 gas turbine, a steam turbine and heat recovery steam generator (HRSG).
Additionally, the unit will use Alstom's upgraded gas turbine technology to offers optimum reliability, operational flexibility, availability and performance to balance load production in the region, which has high power demands from industrial users.
With an installed capacity of approximately 338MW, the new unit will help Iberdrola keep up with growing energy needs in the region.
Alstom Thermal Power president Philippe Cochet said: "Alstom's gas turbines have been in operation for more than ten years on units 1,2,3 and 4 of the Monterrey III power station and we are proud to continue our long, successful partnership with Iberdrola to expand their generation needs.
"This experience enables us to provide superior generation and maintenance solutions that ensure reliability and efficiency for Mexico's industrial consumers for years to come."
Monterrey III is the largest combined-cycle power plant in Mexico using ALSTOM's advanced GT24 gas turbine technology.
Alstom has installed more than 11,000MW worth of electricity generating equipment in Mexico during the five decades, generating nearly 20% of the total capacity, 3,000MW of which correspond to combined-cycle plants.
