Desde o início do processo de privatização, o Setor Elétrico Brasileiro vem passando por significativas mudanças, buscando atender simultaneamente a crescente demanda por energia, o maior rigor das legislações ambientais e a necessidade de diversificação de fontes energéticas, entre outros fatores. Este cenário de crescimento marcado por restrições implica a necessidade de aumento da eficiência das empresas atuantes no setor elétrico e um uso mais racional e planejado dos escassos recursos financeiros, físicos e humanos existentes. A busca pela eficiência se dá de forma distinta nos segmentos que compõem o SEB. Nos segmentos de geração e transmissão, a eficiência é fruto natural da competição inerente ao modelo de leilões de contratação. Na distribuição, segmento que atua sob a forma de monopólio natural, a eficiência é provocada e determinada pela atuação do órgão regulador – a Aneel – por intermédio de definições de regras, parâmetros operacionais e para composição do preço da energia visando à modicidade tarifária. As características distintivas do segmento de distribuição impõem aos gestores das empresas pertencentes a este e aos demais stakeholders do setor elétrico – acionistas, órgãos reguladores e credores – a necessidade de um acompanhamento próximo do desempenho econômico-financeiro das empresas distribuidoras, visando verificar se os distintos interesses envolvidos estão sendo atendidos. Tal fato suscita a necessidade de modelos de análise econômico-financeira de empresas e o levantamento de parâmetros que norteiem a avaliação dos agentes do segmento de distribuição de energia. Este trabalho sugere um modelo para análise econômico-financeira adequado às características específicas das empresas do segmento de distribuição elétrica brasileiro. Intenciona-se que, além do diagnóstico da atual situação econômico-financeira das empresas de distribuição, o trabalho auxilie na elaboração de análises prospectivas, que permitam o estudo de decisões e desenvolvimento de estratégias para manutenção de um bom desempenho futuro das companhias analisadas. O ferramental desenvolvido tem como um dos principais objetivos a praticidade e aplicabilidade do ponto de vista analítico-operacional utilizando informações provenientes de demonstrações financeiras e outros relatórios publicamente disponíveis.

The work aims to analyze UK’s and Brazil’s wholesale electricity trading models. UK’s model, also known as New Electricity Trading Arrangements (NETA), can be considered a reference for the present day electricity markets. Recently UK has implemented a market reform that, while maintaining UK’s market structure, introduced several strong regulatory economic signals in order to foster new investments, both in thermal and in low carbon emission electricity generation. Brazil’s wholesale market model is also noteworthy as it managed to promote large scale investments in low carbon generation in a liberalized market environment. However, Brazil’s regulatory framework design proved fragile during a recent long draught period when short term financial obligations related to imbalance settlements soared and led to financial stress and, eventually to a market halt.

The electrical sector is in the eve of profound modifications due to the market diffusion of several related technologies. Some drivers of this transition are: the increasing support from society for reducing carbon emissions; the growing speed of development and cost reduction of renewable energy generation technologies; new energy storage devices; new automation spread all over the network; a dramatic increase of the computational capacity; and new regulations related to energy usage. Innovation will play a key role in the transition process of the electric sector, promoting changes and creating opportunities for new technology, products, system, regulation and business structures. Since July 2000, law 9.991 established the Brazilian Electric Sector R&D Program that states that 1% of the income of the electric companies must be invested in R&D (research and development) projects, 40% of this overall budget stay under the electric company discretion (the Program is coordinated by the Brazilian electric sector regulatory agency, ANEEL). As a result, BRL 13.5 Billion (approximately equivalent to USD 3.5 Billion) were invested in 4,300 projects from the year 2000 until 2014. What were the results achieved by the Program? And how has it contributed (or not) to the ongoing transition process? To date, no systematic and comprehensive study has looked at the whole period of the Program. This study introduces the first insights of a two-year research project that seeks to address these questions and to fill this gap. It presents an overview of the projects that have been carried out since 2000, and develops a unique methodology that will be used to evaluate the qualitative and quantitative historical benefits of the Program. The methodology considers four perspectives: electric companies, electric sector, academic sector and systems and services providers. It will also present scenarios that will be considered to improve the R&D Program and to inform related public policies and regulations that seek to stimulate Brazilian companies to invest in the electric sector innovation process, and ultimately contribute to the sector’s transition.
In 2004 came into force a new model for the Brazilian Electricity Sector (BES). This model was established based on three pillars: expansion of the installed capacity, reasonable tariffs and universalization of the access to electricity. The main change that took place was the resumption of the energy planning for the State’s responsibility, which had been transferred to private players in the previous liberal period. This resumption takes place through the creation of the Empresa de Pesquisa Energética (EPE), whose purpose is the development of studies and researches to support the planning of the energy sector, guiding the government and industry players in their decision making process and guidelines establishment. Among the major studies carried out by EPE is the Plano Decenal de Expansão de Energia (PDE), that annually formulates forecasts for the expansion of the supply and demand of energy for a period of 10 years ahead, therefore becoming an important planning tool for the BES. Thus, the PDE indicates the future electricity mix for the sector. However, EPE’s planning is only indicative, making it essential to analyze whether their propositions occur in reality. Therefore, the procurement of installed capacity to be added to the BES and the sources that will compose this future mix need to be investigated. Moreover, with the new model, the procurement of new installed capacity starts to occur through energy auctions. In these auctions, the concession of new plants occurs and it is guaranteed the future supply to attend the demand anticipated by the distribution companies for the regulated consumers. The electricity auctions aim to contract energy with reasonable tariffs. In order for that to happen, the criterion used to define the winner is the lowest rate offered. Thus it is through the electricity auctions that the government coordinates the expansion of the generating capacity and the winner sources will compose the future electricity mix. The composition derived from the results of the auctions often differs from the projections of the PDE, making this differentiation the central object of analysis in this article. In that way, the question that arises is what are the causes that explain the differences between the results of these energy auctions and what it was projected and estimated by EPE in its ten-year planning. The article seeks to make a comparison of PDE’s projections since its first formulation in 2006, with the results of the new energy auctions held so far. Essentially, it seeks to answer if, through the indicative planning and the auctions, we are in fact moving towards a strategic electricity mix for the BES.
Since the second half of the 1980s, when electric utilities were first privatized, the ability of the private sector to manage the supply of electricity with safety and quality has become a matter of high relevance for national governments wherever privatization has taken place. In this regard, the severe financial problems that have affected some electric utilities in different countries from time to time, have made it increasingly clear that exposure to financial risk can compromise a utility’s ability to maintain service quality and continuity, and therefore that regulatory authorities should pay attention to the identification and control of utilities’ financial risk exposure. This article aims to explore the factors that could contribute to the financial vulnerability of electricity distribution companies, in order to identify potential instruments for risk recognition and management. This study also proposes to examine possible regulatory policies for monitoring and addressing financial sustainability problems in these companies, a topic which has so far received scant attention in the international literature on electricity regulation. Lastly, this paper will evaluate the feasibility of regulating the financial exposure of electricity distributors.
