The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ambitious reductions in the greenhouse gas emissions from the power sector by 2030 and 2040 are assessed wherein treated as solar targets under ambitious reductions in the greenhouse gas emissions from the power sector. Then, three mechanisms to achieve these selected solar targets are suggested.

This paper reviews current and future incentive mechanisms to promote solar energy. An integrated energy system optimization model shows the most cost-efficient deployment level. Incentive mechanisms can promote renewable sources, aiming to tackle climate change and ensuring energy security, while taking advantage of endogenous energy resources potential. Based on a literature review, as well as on the specific characteristics of the Brazilian power system, under restrictions for the expansion of hydroelectricity and ambitious limitation in the emissions of greenhouse gases from the power sector.

The potential unexploited of solar energy is huge but it needs the appropriate incentive mechanism to be deployed. These mechanisms would be more effective if they have a specific technological and temporal focus. The solar energy deployment in large scale is important to the mitigation of climate change.

The value of the research is twofold: estimations of the cost-effective potential of solar technologies, generated from an integrated optimization energy model, fully calibrated for the Brazilian power system, while tacking the increasing electricity demand, the expected reduction of greenhouse gas emissions and the need to increase the access to clean and affordable energy, up to 2040; proposals of three mechanisms to deploy centralized PV, distributed PV and solar thermal power, taking the best experiences in several countries and the recent Brazilian cases.

This paper aims to assess all the Brazilian electric power transmission line auctions occurred between 1999 and 2017.

A copula-based Roy/endogenous switching regression model is used. The suitability of this model is twofold: it takes into account the selection bias problem involving auctions data and it allows more flexibility in modeling the joint distribution between the unobserved components of the selection and outcome equations; thus, normal distribution assumptions are not needed.

The main results suggest that stated-owned companies have the highest probability of winning an auction, and there is a non-competitive behavior among the players in the auction. The results also suggest some departure from joint normality in the data.

The copula-based sample selection approach used in this paper is consistent under non-normality and allows one to address different types of nonlinearities in the data such as asymmetry and heavy tails.

To investigate the extent to which the contracting mechanisms instituted by the 2004 reform, in particular power auctions, have solved the investment hurdles created by the first reform.

The paper analyses the characteristics of Brazilian contracting and the experience so far with power auctions, concerning investments in generation and electricity prices.

Auctions have been moderately successful, in the sense that they have attracted a fair number of bidders and electric companies have increased their value in the stock exchange, while keeping prices moderate. However, a number of other hurdles to investment – in particular clear and feasible criteria for environmental licensing – have to be solved in order to achieve the reform goals.

The format of power auctions is still going through a learning process; also, the experience has been limited so far, which severely hinders the use of quantitative tools. This could be the object of future research, after more data are available. Of particular interest will be the follow‐up of free bilateral contracting, which has grown significantly.

This could be a useful reference for scholars interested in the recent developments in the Brazilian Electricity Supply Industry.

As far as is known, this is the first paper to systematically analyse the performance of power auctions in the Brazilian market. Its value lies in that it allows an objective evaluation of one central point of the 2004 reform.

Renewables such as sugar-energy biomass can contribute to national electrical security, job creation and mitigation of greenhouse gas emissions. However, after the auction of reserve energy, in 2008, exclusive biomass, in the regulated contracting environment (RCE), the authors observe that this energy environment has lost competitiveness in the auctions. Thus, a study on the present theme is justified, based on the problem: What are the reasons for the lack of competitiveness of sugar-energy bioelectricity in the Auctions of the RCE of the National Electric Energy Agency? The purpose of this study is to understand the situation of sugar-energy bioelectricity in the Brazilian market.

Literature review was conducted through the Scientific Electronic Library Online database, as well as the survey of primary documents at Sugarcane Industry Union and Electric Energy Trading Chamber.

The reasons for lack of competitiveness in RCE electricity auctions are: distant location of transmission lines; difficulties in obtaining licensing; delay in responses from environmental agencies; difficulties in securing financing for electricity generation projects for distilleries; non-pricing of positive environmental externalities as adequate disposal of waste; and the non-recovery of the cost of retrofit of the plants. The present situation may create economic, social and ecological circumstances adverse for Brazilian development, such as a lack of employment and income generation, loss of international currencies from imports of technologies not developed and produced in the country and more significant inefficiency greenhouse gas mitigation.

The originality of this study is in the contribution to the scarce literature on the understanding of the reasons for the lack of competitiveness of the Brazilian sugarcane sector in auctions of the regulated energy environment, based on SWOT analysis and, based on this understanding, to propose solutions for the expansion of this important matrix energy.

Mercado Livre, a site for e-commerce and online auctions, is popular in Brazil. Given the accessibility of user-friendly technology, any person can open an auction on the internet to trade items such as cars, mobile phones, and domestic electrical appliances. In 2012, a media mobilization was sparked after the online auction of Brazilian Catarina Migliorini’s virginity. Described by the Brazilian media as one of the events of the year, the auction was promoted by Justin Sisely, an Australian filmmaker who designed the project Virgins Wanted. Tracing media reports, this chapter focuses on Migliorini’s savvy attention literacies, upon which she capitalized upon the situation to obtain her celebrity. Seizing the opportunity given by a watchful internet audience, she established herself as an iconic personality through press coverage and the curation of online profiles, and became a microcelebrity.

This paper seeks to analyze the relationship between China and the Northeast region of Brazil, aiming to identify how the renewable energy sector is being developed.

The authors analyzed secondary data from the official databases from China-Brazil chambers of commerce to establish the main points related to renewable energy in Brazil's Northeast.

It is possible to notice the main investments, highlighting the wind energy as a more prominent source recently. The authors also point the huge influence from China on Brazil's Northeast energy sector.

It is difficult to identify the amount of Chinese capital due to the large number of mergers and acquisitions that has been taking place in recent years.

Identification of regions that have been receiving investments and the main interests of Chinese investors in the renewable energy sector.

Demonstration of how the renewable energy sector has taken an important turn in Brazil due to Chinese investment.

To evaluate a regional consortium, analyzing its strategies for partnerships with China to help each other in global questions, as is the case of renewable energy.

The paper seeks to examine the evolution of regulatory accounting within the context of the Brazilian electricity sector reforms. The paper traces the process of the reforms and the development of the regulatory accounting system.

The paper is based on data collected from various documents including those published by the regulator (such as laws, resolutions and technical notes), as well as information from distribution companies and other government agencies.

It is found that regulatory accounting played different roles under the different electricity sector reforms implemented in Brazil. For example, regulatory accounting was minimally used during the first reform, and this brought a range of problems of implementation and consolidation of the electricity sector model. However, regulatory accounting played an essential role in the regulatory framework under the second reform, and this in part contributed to addressing some of the problems of the sector.

This is the first study that describes and explains the Brazilian electricity sector reforms by analysing the so‐called core issues in regulatory accounting and tariff review process. The paper contributes to the literature by providing a broader picture of the interconnection between regulatory accounting and the regulator's objectives.

The purpose of this paper is to conduct a literature review on framework agreements, an instrument for demand aggregation adopted in the UK, to recommend improvements to the price registration system (SRP), a mechanism often used with reverse online auctions in Brazil envisaged to promote more flexibility in centralized tenders, allowing public bodies to establish contracts when the need arises, based on registered prices.

A literature review was undertaken to analyze the UK framework agreement approach and the Brazilian SRP. In addition, in-depth interviews with civil servants from the Brazilian Ministry of Economy were conducted to examine the SRP.

The experience with framework agreements in the UK reveals at least four ways to improve the Brazilian SRP: i) extending the legal maximum duration of a price registration minute (ARP) ; ii) allowing the registration of additional suppliers in the ARP, instead of only the first lowest bidder; iii) conducting mini-competitions when a contracting authority decides to use the ARP to enter into a contract; and iv) including additional criteria for awarding suppliers, in line with the most economically advantageous tender (MEAT) approach.

The flow of government financial resources into procurement accounted for approximately 16.5% of gross domestic product in Brazil and for an average of 12% in OECD countries in 2017 (OECD, 2019: 135). Public procurement is a strategic function for enabling an efficient public services delivery and infrastructure deployment. It is, therefore, relevant to examine instruments of demand aggregation to improve the outcomes of public procurement.

Framework agreements are currently not used in Brazil. This paper examines the UK experience with framework agreements to propose potential improvements to the Brazilian SRP, a procurement instrument vastly used in the country.

This paper aims to analyse structural changes within the Brazilian mobile telecommunications market. More particularly, the paper aims to highlight why the market was fragmented and identify drivers for its subsequent consolidation.

Comparative case studies are used to understand change in the Brazilian mobile telecommunications market. The evolution of the market is described and key factors driving change identified.

This paper shows how each of the leading mobile telecommunications groups in Brazil employed a different strategy, both for entering into the fragmented market and for participating in its subsequent consolidation. Attention is also drawn to the role of government in determining market structure, not least in terms of its rationale for initially fragmenting the market in order to encourage foreign investment.

This paper provides a detailed analysis of structural change within the Brazilian mobile telecommunications market. In doing so, it sheds light on the role played by foreign telecommunications companies in the transformation of one of the world's largest, but often overlooked, telecommunications markets.
