The Wind Farm in Maranhão Was Visited by Our Reporting Team. We Bring All the Details in Numbers and Feelings About the Location
The wind farm in Maranhão is located in the lush region of Lençóis Maranhenses, famous worldwide. The complex is a project of Omega, composed in total of 15 enterprises divided into:
- Delta 3, which started operations in 2017;
- Delta 5 and 6, which began operations in 2018;
- Delta 7 and 8, with commercial operation (COD) starting in October 2019.
Our reporting team traveled across the property of the wind farm in Maranhão, located between the cities of Barreirinhas and Paulino Neves.
To navigate among the 172 wind turbines, it is possible to travel by car or ATV, preferably with four-wheel drive. It takes 40 minutes from Paulino Neves to the wind farm or almost two hours from Barreirinhas.

Mato Grosso do Sul excels in the sugar-energy sector: the state reaches a milestone of 22 operating mills and accelerates the production of clean energy in MS with a focus on sustainability.
At the site, the noise from the rotation of the blades is the only thing that breaks the silence of such a calm place, far from any noise pollution. And why not visual pollution? The coastal scenery of the region where the Maranhão wind farm is located is an attraction in itself.
Connected to the nacelle and supported by the tower, the blades (also called wind sails) have an aerodynamic profile, weigh about 17 tons each, and can be over 60 meters long.
The average height of the wind turbines is 120 meters and 300 tons per unit. All this colossal structure has an installed capacity of 426 MW.
Brazil’s Wind Energy Has Higher Capacity Than the Global Average Thanks to the Northeast
The wind farm in Maranhão is just one of the clean energy capturing projects through wind in Brazil’s Northeast. The region is unquestionably at the forefront.
The wind energy produced in Brazil has a higher capacity than the global average thanks to the Northeast, although the country is still ranked seventh in the world for installed capacity.
Of the 726 wind farms in Brazilian territory, 596 are distributed across the states of Bahia (189), Rio Grande do Norte (182), Ceará (81), Piauí (79), Pernambuco (34), Paraíba and Sergipe (1), in addition to Maranhão itself (15).
In total, there are 7,285 wind turbines operating in the Northeast, forming 15,905.1 MW of total power. This represents 88% of Brazil’s production in 2021. This is because the country achieved 19GW of installed capacity this year.
Wind energy represents 10.3% of the national electric grid. According to the Brazilian Wind Energy Association, ten years ago, the sector had less than 1 GW of capacity; therefore, today it is the second largest, only behind hydropower, which accounts for 58.7% of the installed capacity.
By 2024, the Brazilian Wind Energy Association (Abeeólica) estimates that the installed wind capacity in the country will reach 30.2GW.

Partnership Aims for Wind Forecasting Up to Ten Days in Advance
The company Omega, responsible for the Maranhão wind farm, has teamed up with IBM to create a platform to improve the forecasting of renewable energy generation. Resources are used from artificial intelligence and geospatial and meteorological data analysis.
The Renewables Forecasting platform has observation models for providing information such as wind speed and direction, up to 10 days in advance.
The solution is capable of achieving forecasts from large-scale geospatial analyses and data that select and host over six petabytes of relevant data sources. This includes hub height, wind speed, and solar irradiation forecasts.
In May, Vestas closed a partnership with Omega Energy for the supply of 47 turbines for renewable energy projects in Bahia.
