Petrobras will inaugurate wind power installation in the sea

Unprecedented in Brazil, the generation of wind power in the sea begins to take its first steps in the country by the hands of Petrobras. The business promises to be as successful as the wind generation on land, said the director of strategy, organization and management system of the state, Nelson Silva. The bid for the installation of a pilot plant of the company in Rio Grande do Norte will be made this year, revealed the executive, who awaits the licensing of the project at Ibama to start the process.

The idea is to install wind generation towers, or generators in the jargon of the sector, alongside platforms in shallow fields of the northeast, Brazilian region with greater potential to generate energy from the wind. "The advantage in offshore (at sea) is that a factor of capacity greater than on land is expected," Silva explained. The forecast is that the pilot plant starts operating in 2022.

The capacity factor of Brazil, index that measures the degree of utilization of the generators to produce wind power, is one of the largest in the world. In January, the wind complex in Ceará, owned by Echoenergia had an average capacity factor of more than 60% compared to 25% of the world average. The advantage of the generation at sea, they say specialists, is that the wind turbines, or the windmills, can have greater capacity than those installed on land.

Brazil began generating wind power in 2005 – just under 30 megawatts (MW). In 2009, when the first government auction occurred including the supply of wind farms, Brazil generated 600 MW. Today, this generation exceeds 13000 MW and, with only the auctions already made, it must reach 17800 MW in 2023. Currently, wind generation supplies 10% of the Brazilian population, or 22 million of people, according to data from the Brazilian Wind Energy Association (ABEEÓLICA).

"The average capacity of the Brazilian airgenerators on land revolves around 2 megawatts, but in the sea already has a machine operating with 8 megawatts," tells the president of the center of Strategies on Natural resources and Energy (heartwood), Jean-Paul prates, one of the first Proponents of the inclusion of wind energy as a source of power generation in Brazil. This week, he promotes in Rio Grande do Norte the 10th National Wind Forum, where the topic will be discussed, preceding the largest fair in the sector, Brazil Windpower, which will have for the first time a panel dedicated only to the offshore wind generation, with participation of Petrobras.

According to Ibama, Petrobras filed the application for an environmental license for the offshore wind generation pilot plant in May and the body has already issued the reference term for the company to produce the simplified Environmental report (RAS) to obtain authorisation. Because it already has an equipment in the field (platform), Ibama already has environmental study of the site, informed the organ.

And the project is economically viable, the expectation of the director of Petrobras is that it is the first of a series of units that will market electricity in the Brazilian market from the wind generation at sea. To speed up investments, the state seeks the partnership of companies with experience in the segment, such as the Total French and Norwegian Equinor (Ex-Statoil).

"We will use the experience of these companies and the data we have of the measurements of the platforms in the Northeast and the geology of the site, the measurement of winds and tides," explained Silva. According to him, Petrobras is already financially stronger and can start looking at longer-term projects and investing in renewable energy. Source: This is money.
