Under the terms of the agreement, Alstom will provide maintenance services and gas turbine upgrade packages for four GDF Suez natural gas-fired power stations.

The plants use fourteen Alstom GT24 gas turbines to provide enough electricity to more than three million homes in Texas and Massachusetts.

GDF Suez Energy Generation president and CEO Herman Schopman said the contract emphasizes the importance of the company’s reliability and efficiency.

Alstom has to manage and provide replacement parts, technical field advisors and gas turbine services responsibilities for the Midlothian and Hays plants in Texas, and Bellingham and Blackstone power plants in Massachusetts over the life of the contract.

Alstom’s Thermal Services business senior vice-president Hans-Peter Meer said the company has made massive investments in advancing its natural gas power generating technologies to cater to the the long-term needs of its customers.

"For GDF SUEZ Energy North America, those investments will translate into bottom-line benefits once the GT24 upgraded fleet is performing to the new standard in operational flexibility," Meer added.
