The French manufacturer will install eight of its ECO 122 2.7MW turbines at the Pontal 2A project in Rio Grande do Sul in the south of Brazil.
The contract with developer Enerplan is the second deal between the two firms. Alstom was also lined up last year to supply the same turbines for the nearby Pontal 1 project.
Both projects are expected to come online next year. The latest contract includes a five-year operations and maintenance agreement.
In order to meet Brazil's local sourcing rules, the nacelles will be manufactured at Alstom's plant in Bahia state and the towers will be produced at the company's new facility in Canoas, in Rio Grande do Sul.
