Resumo: | The feasibility of hydroelectric generation projects should be tested before the construction of the same. For this are necessary cost estimates, which are usually constructed from historical data. However the construction of these models, with satisfactory precision, can become difficult and even impossible, due to the technical, environmental and social particularities of each Project. In this context several authors have developed equations for determining costs of Small Hydropower in various regions of the world. This article analyzes and compares, using graphical and statistical parameters, three different methodologies for estimating costs applied to the Brazilian scenario with local cost data from actual enterprises. The impact of different approaches on the benefits and on the optimal point of a project to establish a PCH was also checked. The results were analyzed and discussed. |

A viabilidade de empreendimentos de geração hidrelétrica deve ser testada antes da construção do mesmo. Para isto são necessárias estimativas de custo, que normalmente são construídas a partir de dados históricos. Contudo a construção destes modelos, com precisão satisfatória, pode se tornar difícil e até mesmo impossível, devido às particularidades técnicas, ambientais e sociais de cada projeto. Neste contexto diversos autores têm desenvolvido equações para determinação de custos de Pequenas Centrais Hidrelétricas em diversas regiões do mundo. O presente artigo analisa e compara, por meio de gráficos e parâmetros estatísticos, três metodologias de estimativas de custo aplicadas ao cenário Brasileiro com os dados locais de custos de empreendimentos reais. O impacto das diferentes abordagens sobre os benefícios e o ponto ótimo de um projeto de implantação de uma PCH também foi verificado.
