In the region where the terrain Terezinha aerogeradoras towers of 184 were installed Renews energy, for the creation of High Wind Complex, Latin America’s largest Wilderness, with 14 farms. The complex, which will be opened tomorrow, has 294 megawatts (MW) of installed capacity, sufficient to meet the 540 thousand households (about 1.5 million people). The company invested r $ 1.2 billion in the project.
The complex covers the municipalities of Caetité, Igaporã and Guanambi, Bahia in the Southwest, the 750 km of Salvador. About 135 thousand inhabitants of the three municipalities, mainly rural dwellers who lived in extreme poverty, are being benefited by increased income.
In study phase, a project with the Light
In spite of the complex have been ready within the period laid down, they still will not be able to generate energy. This is because the State generating Chesf not completed transmission line and substation required to receive wind energy of renews and throw it in the national interconnected System (SIN). The information is that the company had problems with obtaining environmental permits to build the transmission line of 120 kilometers. But, by the contract signed at the 2009 auction, Renews has guaranteed the payment, by the federal Government, at least 134MW — the energy that she pledged to offer within the deadlines that is fulfilling.
The President and CEO of Renova, Mathias Becker, ensures that, for the company, it does not matter receive without generating energy. So, search collaborate to accelerate the construction of transmission line. The prediction is that this only be ready in September of next year.
The Mayor of Caetité, José barrier (PSB-BA), says the arrival of Renova was very good for the region in economic terms, not only for the generation of jobs in the construction and operation of complex, but primarily by social projects, such as the Pinwheel Program, and improving the income of the rural population, which was very poor, which increased the local economy.
With its new source of income, Terezinha, for example, has managed to build a home for one of his sons. Some have only a tower in his lands, but there are those who have up to 11 — and each one of them receives $ 5,500 a year, the market value. A big change for those who lived from family agriculture for subsistence, primarily cassava, tomato planting, Palm and grass, these two for livestock.
When the Renews arrived, many residents were suspicious and not agreed to lease the land. The company had to change the project and change the location of some towers. Today, Terezinha, who was against is sorry.
Aniruddha Barbosa Neto and his wife continue planting cassava, it takes to sell in the city in a bullock cart that he even built. Their income was R $ 400 annually. Now, with that receives your lease land, by account with pride, it pays to the Faculty of medicine in Salvador for one of his eight children:
— I wasn’t afraid, my income has improved a lot, I can not afford to speak, was a beauty. And now I’m paying for my son’s College. This tower for me was a wonder. But I had people that lost sleep with fear of losing ground.
Becker also that, in October, Renews initiates more complex two wind farms, with investments of R $ 1.8 billion. The first will have six wind farms with 103 towers, with an installed capacity of 153MW. It should come into operation in September 2013. The other will have nine parks with 127 towers and installed capacity of 212, 6MW. This is planned for July 2014.
More R $ 1.4 billion will be invested in a project still in the process of detailing, 400MW, with energy that will be sold to the Distributor carioca. This is 25.8% of the share capital of Renova, acquired earlier this year for $ 360 million. The other partner controller is the RR participations, founder of Renova, Ricardo Delneri and Renato Amaral.
Becker also says that until the beginning of August the BNDES will enter as a partner, with a contribution of $ 315 million, going to have 12% of the total capital.
The price of wind power has been dropping each year. According to the Coordinator of the complex of the high hinterland, Roberto Araújo, in the first auction in 2009, energy contracted out r $ 144,99 the megawatt-hour (MW/h). As for the Park which will come into operation in 2013, the cost was R$121,25 MW/h. for the third, dropped to $ 98,53 MW/h.
Brazil prepares to jump in the sector
Ever the winds are blowing so strong in Brazil. Next year the country will become the tenth in the world in installed capacity, with 5,183 megawatts (MW) of wind generation — today, is at 20 place. The projection is the President of energy research company (EPE), Maurício Tolmasquim, to remember the projects that will come into operation, such as Renova energy, starting this year. And Brazil already has the lowest price of wind energy in the world, around R $ 105 megawatt-hour (MW/h).
— The wind generation became competitive. Of course we need of thermal power plants, because it can have a day with less wind. But reduce the firing of gas thermal — says Tolmasquim.
This year the wind power generation will more than double in 2011, from 1,471 MW to 3,135 MW. With the projects under construction, the expectation is to reach the 2016 with wind generation capacity of 8,088 MW, six times more than in 2011.
Second Tolmasquim, wind power has become more competitive with coming to the country from numerous manufacturers in search of new markets, due to the crisis in Europe. And, in Brazil, wind energy can complement the water, since the greater frequency of winds occurs between May and November, the dry period of the rivers, when we need to reduce the generation in hydroelectric plants.
— Do not have how to store wind power. But you can stock it in reservoirs of hydroelectric plants in the form of water. In the time that is windy, for sure generate the hydro and stocks-if the water in the tank. When it stops ventar, uses water to generate. The reservoir is a water battery — says Tolmasquim.
The estimated wind power potential in Brazil today is 143 000 MW, but Tolmasquim believes it can reach 300 thousand MW. That’s because this potential was calculated considering torres 50 m tall, and today there are already 100 m 80 m towers, which raises the generating capacity.
Thermal — has the fuel cost and the environmental impact that wind does not have. The wind is an important complementary source of energy — says Tolmasquim
