Abstract(s)
As alterações climáticas e a crise petrolífera de 1973 foi o ponto de partida para consciencializar os governantes da escassez e da dependência dos recursos energéticos provenientes de combustíveis fósseis. Aliados a este dilema, o aumento do preço do barril de petróleo e a instabilidade política dos países que produzem, conduziu à necessidade de mudança e procura de novas soluções. Em Portugal, a incorporação das energias renováveis na sua matriz energética contribui para uma mudança no paradigma energético. Os incentivos legislativos à produção para autoconsumo, com recurso a energias renováveis, e em particular os sistemas fotovoltaicos (energia solar), em conjunto com o declínio substancial no custo dos sistemas fotovoltaicos (redução de 80% desde 2008) permite á energia solar competir com outras opções de geração de energia. Outro motivo para o crescimento fotovoltaico são os mecanismos de financiamento inovadores, proporcionando uma solução para os custos iniciais e para os custos de operações e de manutenção do sistema solar.
O Modelo de Negócio Third party ownership (TPO) já bem-sucedido em alguns países desenvolvidos (EUA, Japão), e os seus dois principais instrumentos, o leasing solar e o Power Purchase Agreement (PPA) permitem aos consumidores obterem energia limpa a um preço inferior ao do mercado da eletricidade. Utilizando o conceito de Modelo de Negócio como ferramenta analítica, a presente dissertação pretende comparar a atratividade económica de dois modelos de negócios nas empresas solares na implementação de energia fotovoltaica. Proceder-se-á a uma avaliação económico-financeira do caso de estudo com o intuito aferir do retorno financeiro.
Os resultados do caso de estudo sugerem a viabilidade económica dos dois modelos de negócios, apresentam resultados semelhantes, com retorno do investimento para a empresa promotora. Podendo desempenhar, os dois modelos de negócios, um papel importante num rápido crescimento das energias renováveis em Portugal.
The climate change and oil crisis of 1973 was the starting point to raise awareness of the scarcity and dependence on energy resources from fossil fuels. Allied to this dilemma, the increase in the price of a barrel of oil and the political instability of the countries that produce it, led to the need for change and the search for new solutions. In Portugal, the incorporation of renewable energies in its energy matrix has contributed to a change in the energy paradigm. Legislative incentives for production for self-consumption, using renewable energies, and in particular photovoltaic systems (solar energy), together with the substantial decline in the cost of photovoltaic systems (80% reduction since 2008) allows solar energy to compete with other power generation options. Another reason for photovoltaic growth is innovative financing mechanisms, providing a solution to the initial costs and the costs of operations and maintenance of the solar system. The Third party ownership (TPO) Business Model already successful in some developed countries (USA, Japan), and its two main instruments, the solar leasing and the Power Purchase Agreement (PPA) allow consumers to obtain clean energy at a lower price than the electricity market. Using the Business Model concept as an analytical tool, this dissertation aims to compare the economic attractiveness of two business models in solar companies in the implementation of photovoltaic energy. An economic and financial evaluation of the case study will be carried out in order to assess the financial return. The results of the case study suggest the economic vability of the two business models, with return on investments for the promoting company. Both business models may play an important role in the rapid growth of renewable energies in Portugal
