The French manufacturer will deliver the 127 turbines between January 2017 and January 2018 to the 355.5MW Umburanas complex in the Bahia state.
The order is made up from a mix of Eco 122, Eco 110 and Eco 100 turbine models, which have a unit capacity ranging from 2.7MW to 3MW.
The turbines will be manufactured at Alstom's Camaçari plant on the east coast of Brazil.
It is part of the 1.2GW memorandum of understanding framework signed between the Alstom and the Brazilian developer in 2013.
In April last year, as part of the EUR 1 billion+ agreement, Alstom received an order to supply 513MW of the Eco 100 class turbines to multiple projects in Brazil.
According to the firm, it has now signed contracts with the equivalent to 2.5GW in capacity for projects in Brazil.
