ANÁLISE DOS LEILÕES DE ENERGIA EÓLICA BRASILEIRA NO PERÍODO DE 2009 A 2017

With climatic variations, hydraulic energy conversion, which is prevalent in Brazil, is compromised, impacting the generation of electricity. In this scenario, wind generation has advantages to be implemented in the country. In order to analyze the contracts signed in wind energy auctions in Brazil, between 2009 and 2017, an exploratory research was carried out considering the technical, economic and regulatory aspects, revealingpositive impacts, such as: a higher generation in the period when the reservoir levels of hydroelectric plants are low; jobs; lower cost of sale; low environmental impact. As a negative impact, there is a failure to deliver energy on the stipulated date. In the period analyzed, 11,553 wind energy contracts were sold. Of these, 521 contracts did not enter in the generation situation, what represents4.5% of the total. This corresponds to an amount of energy traded in the order of 95,027,305 MWh that was not injected into the transmission network, having a total of R$ 15.76 billion, which is equivalent to 7.1% of all electricity generation in Brazil in the period under review. This scenario causes an imbalance in the sectors of Brazilian energy planning, in which they need to activate other mechanisms of electric generation, such as thermoelectric ones, to supply the demand, harming the final consumer, which, consequently, will have a higher cost due to the increase in operational values. The projects that will be left without the supply of electricity contracted at auctionwill have an impact on the production of goods or services, reducing the maintenance and creation of new jobs and contractual difficulties in guaranteeing services.
