- What is it?
Wind is produced by the energy contained in the air, molecules in movement.
The wind can be transformed into useful energy. Wind energy conversion systems are called wind turbines (modern and industrial size machines) or windmills (old-fashioned or smaller machines).
Wind turbines capture the air’s kinetic energy, transforming it first into mechanical and then into electrical energy.
In simple terms, the force of the wind hitting the wind turbine’s blades causes the central hub of the machine to turn, thus powering an electric generator. The location of the blades and generator atop a tower provides the best access to the wind, in the same way that a flag atop a flagpole is lifted aloft. The electricity produced is injected into the electric system and transmitted to consumers.
A group of wind turbines in the same geographic area forms a windfarm, wind energy park, or wind energy project. This electric energy from the wind contributes significantly to the large-scale generation needs of the electric power system.
- Brazilian wind energy potential
Brazil is naturally priviledged in terms of its energy resources, and particularly as regards renewable energy. In addition to its hydroelectric, solar and biomass potential, the country has an enormous potential for wind energy generation.
The Brazilian wind energy resource has been estimated as being on the order of 145 GW, at 50 meters’ hub height, according to the Brazilian Wind Energy Atlas (Atlas do Potencial Eólico Brasileiro (MME-2001)). Modern wind turbines use towers of at least 100m in height and this indicates that the national potential could even far exceed the 145 GW estimate.
The Brazilian wind energy market began to grow with the creation of the PROINFA Renewable Energy Source Support Program (“PROINFA – Programa de Incentivo às Fontes Alternativas de Energia”), created by Law 10.438/02 and administered by ELETROBRAS, the holding company for the public energy utilities within Brazil’s electric sector. This program contracted approximately 1,422 MW generated by 54 wind energy projects.
Starting in 2009, the renewable energy auctions (“Leilões de Energia de Reserva e de Fontes Alternativas”), carried out and regulated by agencies of the federal government, have provided a major new market on a scale sufficient to attract a broad spectrum of manufacturers, project developers and service providers, creating an environment of healthy competition, diversity, and maturity, as well as providing long term stability for investors.
- Sustainability
Wind energy is one of the most promising new sources of energy, principally because it’s renewable and economically competitive, and, if used to substitute fossil fuel generation, helps to reduce greenhouse gas emissions. Wind energy has enjoyed an annual growth rate of 25% and worldwide installed wind energy capacity is expected to reach 200 GW by the end of 2010 (equivalent to the generation of about ten hydroelectric dams the size of Itaipu).
Wind energy projects don’t interrupt tradional uses of the land, don’t displace landowners, and are compatible with other economic uses of the land. Landowners receive rent, and this, combined with jobs created during construction and operation, stimulates the regional economy, which can be of substantial importance in poorer regions. Wind energy projects do not produce pollutants and have very few impacts, most of which can be minimized with good engineering.
Wind energy contributes to the diversification of the Brazilian energy system, reducing dependence on other sources. Wind energy is highly complementary with hydrolectric energy (another renewable energy source) and helps to preserve water in reservoirs during periods of drought.
The introduction of new tecnologies and/or markets requires the attraction and training of professionals drawn from diverse areas, generating jobs and income. Furthermore, many wind energy projects will be installed in Brazil’s rural areas, in small towns, injecting both significant investments and tax income. Newly created infrastructure (roads, bridges and electrical systems) will reduce social inequality and improve the quality of life for local residents.
Finally, society must choose the best form of energy to support its social and economic growth. Today’s citizens recognize that wind energy can contribute significantly to the planet’s present and future well being. This is a responsibility of all and Casa dos Ventos is pleased to do its part.
The tables below show the projects developed by Casa dos Ventos and selected in each of the 2009 and 2010 renewable energy auctions.
The graphic below shows, by state, the projects that Casa dos Ventos currently has under development:
Throughout the country’s territorial extension and particularly in the northeast and south, Brazil has shown an extraordinary wind energy resource. Casa dos Ventos has conducted an extensive campaign to identify the areas with superior wind resources, starting with partnerships with landowners.
With the formation of this partnership, the regional wind energy measurement campaign begins, and, should the site demonstrate suitability for wind energy generation, the development process begins and continues through construction and operation.
Throughout this process, from the time the land rental contract is signed until the project ceases generation, the landowner obtains numerous benefits.
One of the most high-impact benefits of the presence of a project developed by Casa dos Ventos is the financial benefit. The landowner is a partner in the process and receives remuneration for ceding the right to use the property for wind energy generation. A portion of the income generated by energy sales goes to the landowner, who continues to own the property and, in addition to this source of income, may also have income from oncoming agricultural and stock operations. This duality is made possible by the fact that the wind energy project generally has a very limited impact on other activities on the property.
The installation of a wind energy project brings additional benefits for the region. For example, area roads are often improved to accommodate the transport of heavy equipment. In addition to infrastructure improvements, communities often see addition Jobs and income generated by the project, bringing new dynamism to the local economy. Further benefits often include increases in tourism in the region and increased fiscal revenues for the municipality and state. Finally, one of the most important benefits is the project’s contribution to the environment. The region can take credit for environmentally responsible energy generation that doesn’t cause greenhouse gases or flood forested areas.
Innumerable landowners, and their associated communities, have benefited from projects developed by Casa dos Ventos. The company continues to identify new areas with wind energy potential, that become new locations for sustainable development, always seeking a harmonious relationship between the environment, landowners, and local communities.
Expectativa com leilões é de 2.000 MW
Com a expectativa de contratação reduzida de 2.500 para 2.000 MW, segundo o diretor executivo da Associação Brasileira de Energia Eólica (Abeeólica), Pedro Perrelli, o preço da energia nos leilões de contratação de projetos para a geração de energia com base nos ventos será de R$ 167/MWh para ambos os leilões: de reserva e de A-3.
Os leilões, incluindo os de biomassa e PCHs (Pequenas Centrais Hidrelétricas) estão previstos para hoje e amanhã, e ambas as categorias apresentam características específicas no que diz respeito ao destino da energia gerada, de acordo com a Empresa de Pesquisa Energética (EPE), que habilitou tecnicamente as empresas que manifestaram interesse em participar do certame.
O leilão de reserva tem como objetivo garantir o fornecimento de energia elétrica no País nos casos em que ocorrer aumento da demanda.
Outro objetivo é o de contribuir na recuperação dos reservatórios hídricos, responsáveis pela maioria esmagadora da energia gerada no País.
A energia adquirida com o leilão de A-3, no qual todos os empreendimentos devem ser entregues em até três anos depois da conquista da licença, é destinada ao suprimento da demanda do mercado.
Essa demanda deve ser indicada pelas distribuidoras de energia em programações previamente apresentadas à EPE e que estejam de acordo com o Plano de Desenvolvimento Energético estabelecido para o período de 2010 a 2019. Prazos
Desde 13 de agosto, as empresas habilitadas pela EPE tiveram que depositar as garantias, na Câmara de Comercialização de Energia Elétrica (CCEE), para participarem nos leilões.
Ao todo, foram habilitados 316 projetos eólicos para o leilão de reserva, num total de 8.202 MW, que deverão estar em plena operação em setembro de 2013. Na oferta de A-3, 320 projetos eólicos foram habilitados, com 8.034 MW e devem estar em geração em outubro de 2013, dentro do prazo previsto para esse tipo de certame, que é de três anos a partir da licença.
Ceará
Correspondendo ao potencial eólico do Estado, os empreendimentos cearenses destacam-se na disputa. Ao todo, o Ceará conta 96 projetos habilitados para participar do Leilão de Reserva de Fontes Alternativas.
No de A-3, são 92 empreendimentos cearenses habilitados. Os projetos deixam o Estado em segundo lugar, perdendo apenas para Rio Grande do Norte, que lidera em número de empreendimentos.
DIAGNÓSTICO
Arce realiza a 1ª fiscalização do parque da Prainha
A Agência Reguladora de Serviços Públicos Delegados do Estado do Ceará (Arce) realiza, hoje, a primeira fiscalização prevista pelo convênio de descentralização acordado com a Agência Nacional de Energia Elétrica. A visita dos técnicos da Arce ocorrerá na usina da praia da Prainha, em Aquiraz.
No convênio, a Arce foi licenciada para regular o funcionamento de 10 usinas cearenses. "Lá, vamos fazer um diagnóstico da usina. Vamos para saber se ela está cumprindo aquilo para que foi pensada", declara Eugênio Bittencourt, coordenador de energia da Arce.
De acordo com ele, será avaliada a licença ambiental de operação, o registro de ocorrência e os boletins diários de operação, assim como as normas e os contratos de concessão que regem a usina, "entre outros aspectos".
As próximas usinas a serem fiscalizadas serão Lagoa do Mato e Canoa Quebrada, em Aracati, ambas em setembro.
