“…In the long term, the transmission infrastructure must be restructured to meet changing requirements and eventually yield an efficient integration of renewable energy generation [42,43]. Although Brazil account with the highest potential of wind power [16,44,45], from our results found that coordination of energy policy is a crucial aspect for obtaining the reduction of asynchrony on the supply chain.…”

“…Given the role of wind industry for the Brazilian electricity market, this paper surveys unsynchronised energy policy related with time-delays of Int J Elec & Comp Eng ISSN: 2088-8708  construction of transmission lines and recent changes of the auctions' policy in practice that affects the development of wind-power supply chain. Despite an increase of auctions for transmission lines in the last year, Brazilian electricity market faces drawback related with the delays to build extensive transmission network for energy supply [7], [16][17][18]. Currently, reduction in auctions in the short term, as present in Figure 1, and the more considerable variability of electricity prices in the medium and long term represents a significant challenge for wind industry investments.…”

Previous studies have shown that poor performance of energy supply chains arises from incorrectly interpret feedback information and time delays between decisions and actions in energy policy. This paper assesses alternatives to improve performance of wind-power supply chain with transmission constraints that contribute to enhance response capacity of the wind industry to changes of energy policy. In order to test these alternatives, this paper used a simulation model with system dynamics (SD), taking as case study Brazil. The simulation model represents the main time lags and fluctuations that exist in the wind-power supply chain. Four simulation scenarios were proposed to evaluate changes in auction-based policy in wind industry of Brazil. The results are related to operational capacity, inventory levels and response capacity. This paper provides an analysis of different scenarios that contribute with synchronization of auctions policy, including transmission capacity constraints.

ResumoApesar da energia eólica ser considerada uma matriz energética "limpa", estudos apontam que a implantação de parques eólicos no Nordeste brasileiro está causando diversos impactos sociais e ambientais negativos às populações que vivem no litoral. Esta pesquisa teve como intuito demonstrar que o investimento em energia eólica no Brasil, com enfoque no estado do Ceará, apesar de ter sido forjado a partir de um discurso conservacionista e regionalista, na realidade, direciona os benefícios da geração de energia eólica para grupos externos, com ausência de retorno financeiro local e, de forma mais agravante, causando prejuízos materiais e imateriais aos moradores que vivem próximo às usinas instaladas. O estudo revelou que as leis que regem o ordenamento da atividade no Brasil facilitam a implantação dos parques eólicos em detrimento da boa aceitação popular, sendo comumente utilizados mecanismos para "invisibilizar" os moradores locais. No final, foram sugeridas medidas para um melhor gerenciamento das políticas de implantação de parques eólicos no Ceará, de modo a possibilitar que as comunidades locais sentem à mesa de negociação e se beneficiem diretamente com os lucros do mercado de geração de energia eólica.Palavras chave: Energia Eólica; Políticas Públicas; Nordeste do Brasil; Impactos Sociais. AbstractAlthough wind power is a "clean" energy source, studies show that wind-farm implementation in northeastern Brazil is causing diverse social and negative environmental impacts to people who live in coastal areas, especially traditional fishers, small farmers, runaway slave communities (quilombolas), and indigenous groups. Social opposition to wind farms grows daily, and people allied with social movements, associations, human rights organizations, and universities have made many local interventions to stop construction. This research aims to demonstrate that even though investments in Brazilian wind power, especially Ceará state, were based on a conservationist and regionalist discourse, wind power benefits actually flow to outside groups without financial returns accruing locally, and, even worse, causing material and non-material damages to people who live near wind farms. This study reveals that laws regulating wind-power development in Brazil facilitate the implementation of wind farms to the detriment of broad social acceptance because it is a means to make local residents "invisible," as in the case of exclusion of communities on maps used to obtain environmental licenses or land-title fraud (grilagem) of collective and historical land claims. Finally, we suggest measures for better control of policies for wind-farm development in Ceará that would make it possible for communities to negotiate as equals with wind-power investors and obtain benefits from the profitability of wind-power generation.Key words: Wind Energy, Public Policies; Northeastern Brazil, Social Impacts ResumenAunque la energia eólica sea considerada como una fuente energética "limpia," las investigaciones muestran que la implantación...

“…A wide variety of studies have evaluated wind resource potential in regions such as offshore of Ceará, Brazil [5], onshore in the Arabian Peninsula [6] and the entire United States, both onshore and offshore [7]. Further studies have integrated wind speed with turbine power curves to create generation profiles offshore of California (not including the Humboldt Call Area) [8,9], Oregon [10], the east coast of the United States [11], northern Spain [12], the Persian Gulf [13], and the gulf of Thailand [14], and onshore in Rafha, Saudi Arabia [15], South Africa [16], and Algeria [17].…”

Floating offshore wind is being considered in northern California as indicated by the Bureau of Ocean Energy Management’s issuance of a lease consideration in the Humboldt Call Area. Humboldt County offers access to this enormous resource, but local electric load and transmission are limited. The potential impacts of offshore wind generators at three different scales were studied using a regional grid model of Humboldt County. Offshore wind generation was calculated using modeled wind speed data and 12-MW turbine specifications and integrated with projected load and historical generation. Offshore wind farms deployed in the Humboldt Call Area achieve annual capacity factors between 45% and 54% after losses and maintenance. Power output is variable between and within seasons, with full power output 30% of the time and no output approximately 20% of the time. Electricity from a 48-MW wind farm provides 22% of regional load with limited exports. A 144-MW wind farm serves 38% of local load, exporting 40% of its electricity with the extant 70-MW transmission capacity. A full build-out of 1836 MW would result in 88% curtailment with existing transmission. Across scenarios, offshore wind variability necessitates reliance on existing power plants to meet local demand in periods of low wind.
