pt-logo Português logo-esp Español

“The City of Boa Esperança (MG) must have soon the country’s first power plant that will generate electricity from waste. The project, led by Furnas Centrais Elétricas, has had its first phase completed after tests are carried out in an experimental plant In Mauá, in the interior of São Paulo.The next step is the construction of the plant in the Southern region of Minas Gerais state, which will have a capacity of 1 MW and will be interconnected with the Minas Gerais Energy Company (Cemig).”

This seminar is part of the international cooperation between the Universidade Tecnológica Federal do Paraná and the Universidad de Pinar del Río (UPR) funded by the MÊS/CUBA call of CAPES. The project is in the third year of completion and ends in 2018. In addition to the work missions, study missions are being carried out as part of this year’s visit by Prof. Arielys. Prof. Decio Estevão do Nascimento will be doing his post-doctorate at UPR by the end of this year.

The project is financed by the funding call (Edital Universal) and this time has new partners, such as Unioeste and UNILA.

This project is part of the internationalization efforts of the Postgraduate Program in Technology and Society (PPGTE) and the Planning and Public Governance Program (PPGPGP). It also has the support of and joint actions with the Department of Management and Economics (DAGEE).

Map shows: Paraná is more ‘solar’ than previously thought

According to the “Solar Map” project of Itaipu the state of Paraná has untapped potential – and this is also because of a wrong image about the use of solar energy!

“Paraná has a great potential for solar energy to be explored. The average values of radiation and productivity of the State is higher than in 29 countries in Europe and 59% higher than the average of Germany, the country with the largest installed capacity in the world “This information is part of the latest survey, done in 2006. This database is undergoing an update and will be part of the first Solar Energy Atlas of Paraná, which is expected to be released in the second half of April.

Analysis of the Expansion Possibility of Small Central Hydro powers in Brazil

pt-logo Português

A research article by the researchers on the identification of the key limitations and potentials of sustainability in the productive chain for Small Hydro Power (SHP) in Brazil by Prof. Dr. Christian Luiz da Silva (UTFPR), Masters student of the PPGTE program Georgia Alana Andréas Nowakowski (UTFPR), and the Cuban researchers Alain Hernandez Santoyo (Universidad de Pinar del Rio, Cuba), VictorErnesto Perez Leon (Universidad de Pinar del Rio, Cuba), and Mayra Casas Vilardell (Universidad de Pinar del Rio, Cuba) was published in a Special issue (Edição Especial Nexo Água e Energia) of the Journal Desenvolvimento e Meio Ambiente.



Small hydro power plants are considered strategic in the expansion projects at the National Energy Plan in Brazil. However, it is not clear how this expansion can effectively occur, considering that only hydraulic potential is not sufficient enough to guarantee it. In this sense, the main objective of the present research is to identify the key limitations and potentials of sustainability in the productive chain for Small Hydro Power (SHP) in Brazil, to the context of environmental, social, economic and institutional dimensions. Regarding the research methodology, it can be classified as applied and exploratory. The data used is secondary and was used a qualitative analysis technique.
To identify limitations and potentials, a mapping of SHP production chain structure was done at national scale. Five stages that compound the production chain were studied: natural resources; generation; transmission; distribution; and marketing. According to these stages, five criteria were used (importance, probability, timeliness, scope and effect) to classify factors identified in each step.
Finally,it is established an aggregations criteria and a significance level for the potential and the limitations of each chain stage was defined. As a result, 20 limiting and 17 potential related to the productive chain of SHPs inBrazil were identified. In order to make the sector more competitive, efforts needed to reduce the negative environmental impacts arising from the power plants installation were found, such as the flooded areas and the resettled families, and the establishment of some legal and technical aspects related to the environment and energy trading. On the other hand, the hydraulic potential and consolidation of turbine manufacturers and generators ratify the SHP as strategic and potential for the country.

Renewable Energy Project Investment In Emerging Markets Yields Higher Returns

pt-logo Português

The news page on renewable energies Clean Technica reports that investments in renewable energy projects in emerging markets yield more. Read the full article here: Renewable Energy Project Investment In Emerging Markets Yields Higher Returns.

Investing in renewable energy projects in emerging markets has returned that are on average 28% higher than those in Europe or North America.

The findings are part of the recently released Mercatus Global Advanced Energy Insights Report Volume IV, published by cloud-based software company Mercatus, which offers software to help digitally assess renewable energy deals. The report is based on energy project data in various stages of development managed in Mercatus’ Energy Investment Management Platform in 2015. Specifically, taken in aggregate, the internal rates of return for renewable energy projects in the developing world are 28% higher than those in Europe and North America.

safricasolarroofinstall-e1348142674385“It may be time to re-think J. Paul Getty’s famous formula for success: rise early, work hard, strike oil,” said Haresh Patel, CEO of Mercatus.”For energy investors today, the more successful formula might revolve around renewable energy projects-particularly in emerging markets. If there was an exchange-traded fund (ETF) for these developing world projects, I think investors would seriously consider buying stock. ”

Several key points are worth taking out of the report:

In 2015, rapid growth was seen for the development of advanced energy technologies in developing countries, with investment in these markets matching that of developed countries for the first time. This matches figures revealed in March by the United Nations Environmental Program, which showed that in 2015, investments in renewable energy in developing nations topped investments in the developed world for the first time ever. Developing and emerging economies invested a total of $ 156 billion in renewable energy in 2015, while developed nations invested $ 130 billion.

Unsurprisingly, therefore, Mercatus concludes that “emerging markets represent the largest source of growth in demand for electricity and growing investment opportunities for advanced energy technologies” over the long term.

Furthermore, on a wider scale, Mercatus also found that energy companies are increasingly diversifying across technologies and geography, providing more options for consumers and minimizing risk and capturing more sectors for them.


Perhaps the most interesting of the findings from the new report, however, is the fact that it appears developed nations are more interested in smaller-scale solar projects, while developing nations are looking to larger, utility-scale solar projects. Average project size in Europe is 3 MW, and in North America 11 MW. However, average project size in South America is 64 MW, in Africa it is 45 MW, and 34 MW in the Middle East.

This is unsurprising, given the existing electricity infrastructure in developed nations – where renewable energy is a transitional electricity source. In developing nations, however, the electricity infrastructure is not as entrenched and developed, meaning that lower cost renewable electricity projects are not only good for the environment and national climate targets, but economically more viable than traditional fossil fuel-based generation projects.
