Wärtsilä signs an operation and maintenance contract with Rio Amazonas Energia, a Brazilian power distribution company, for the Cristiano Rocha power plant in Manaus, Brazil.

O&M agreement to strengthen the relationship between Wärtsilä and Rio Amazonas Energia

This plant is equipped with five Wärtsilä 50SG gas engines, with a combined net capacity of 92 MW. The fast start-up and shut-down capability of Wärtsilä engine technology allows the plant to reach full power in just a few minutes. It thus ensures a stable and reliable power supply and stability of the network.

This O&M agreement, effective February 1, 2023, will last 28 months. It aims to strengthen the existing relationship between Wärtsilä and RAESA, which had signed an asset performance guarantee agreement in November 2019 to help the plant run on 100% natural gas. The Cristiano Rocha power plant supplies 65 MW of electricity to the national grid through a power purchase agreement with Eletronorte.

Wärtsilä expands its relationship with RAESA to ensure stable and reliable power supply

RAESA’s technical director, Edesio Alves Nunes Filho, said their goal is to be the most reliable and profitable power producer possible in the Brazilian energy market. Wärtsilä’s expertise and ability to offer a complete O&M solution were the main reasons why RAESA chose the company to oversee the O&M needs of the Cristiano Rocha power plant.

Carlos Henrique Gonzales, Wärtsilä’s director of business development, added that Wärtsilä aims to offer the best solution in terms of scope, knowledge and value. By extending their relationship with RAESA to cover the operations and maintenance of the Cristiano Rocha power plant, Wärtsilä will be able to ensure that the plant can continue to provide electricity 24/7 while maintaining low costs and high performance.
