Technology group Wärtsilä has signed a five-year operation and maintenance (O&M) agreement with an outcome-based performance model covering three power plants owned by Âmbar Energia, the energy company of J&F Group in Brazil. The agreement, booked by Wärtsilä in Q3 2025, sets defined performance targets to ensure uninterrupted power availability and reliability, aligning both parties around shared results.
Located in the Amazon city of Manaus, each of the three plants delivers 92 MW of power from five Wärtsilä 50SG engines. The facilities were recently converted to run on natural gas, making them the first in Brazil to complete such a transformation.

The outcome-based structure links financial outcomes to operational performance, encouraging a results-driven partnership between Wärtsilä and Âmbar Energia. Wärtsilä will focus on maintaining high efficiency, reliability, and cost predictability through proactive maintenance, spare parts supply, and digital monitoring to maximise uptime and productivity.
“This agreement with Wärtsilä aims to create value for our business through increased operational efficiency, cost savings, and regulatory compliance. Wärtsilä’s advanced digital tools, predictive maintenance, and lifecycle expertise will help us optimise our assets,” said Fábio Bindermann, operations director at Âmbar Energia.
“This outcome-based agreement with Âmbar Energia ensures that we will achieve shared goals together, taking us a step closer to our decarbonisation targets. It reflects mutual accountability and long-term collaboration,” added Gaston Giani, energy business director at Wärtsilä Energy.
Âmbar Energia, part of Brazil’s largest private conglomerate, J&F Group, operates 43 power generation units across natural gas, hydro, solar, biomass, coal, and biogas. The company is the fourth-largest natural gas power generator in Brazil by installed capacity, contributing to the diversification of the nation’s energy mix.
