Brazil has the largest electricity market in South America. Its installed capacity is comparable to that of Italy and the United Kingdom, although with a much larger transmission network. The country has the largest capacity for water storage in the world, being highly dependent on hydroelectricity generation capacity, which meets over 80% of its electricity demand. This dependence on hydropower makes Brazil vulnerable to power supply shortages in drought years, as was demonstrated by the 2001-2002 energy crisis.
The National Interconnected System (SIN) comprises the electricity companies in the South, South-East, Center-West, North-East and part of the North region. Only 3.4% of the country's electricity production is located outside the SIN, in small isolated systems located mainly in the Amazonian region.

Electricity Supply and Demand
- Hydro: 73,678 MW (76.5%)
- Gas: 10,798 MW (11.2%)
- Oil: 4,446 MW (4.6%)
- Renewable: 3,930 MW (4.1%)
- Nuclear: 2,007 MW (2.1%)
- Coal: 1,415 MW (1.5%)
Generation capacity in Brazil is dominated by hydroelectric plants, which account for 77% of total installed capacity, with 24 plants above 1,000 MW. About 88 percent of the electricity fed into the national grid is estimated to come from hydroelectric generation, with over 25% coming from a single hydropower plant, the massive 14 GW Itaipu dam facility, located between Brazil and Paraguay on the Paraná River. Natural gas generation is second in importance, representing about 10% of total capacity, close to the 12% goal for 2010 established in 1993 by the Ministry of Energy and Mines.
This reliance on abundant hydroelectric resources allegedly reduces the overall generation costs. However, this large dependence on hydropower makes the country especially vulnerable to supply shortages in low-rainfall years (See The 2001-2002 crisis below).

New generation projects
Brazil needs to add 6000 MW of capacity every year in order to satisfy growing demand from an increasing and more prosperous population. The Brazilian Ministry of Energy has decided to generate 50% of new supplies from hydropower, 30% from wind and biomass such as bagasse, and 20% from gas and other sources. Wind in the North-East is strongest during the dry season when hydropower plants produce less, so the two energy sources are seasonally complementary.
Brazil has an untapped hydropower potential of 180,000 MW, including about 80,000 MW in protected regions for which there are no development plans. The government expects to develop the rest by 2030. Most new hydropower plants are run-off river plants that are less damaging to the environment, because their reservoirs are small. However, they are more vulnerable to droughts and less efficient, because only a fraction of their capacity can be used during the dry season.
The National Agency for Electricity (ANEEL) has commissioned feasibility studies for several hydroelectric plants (small, medium and large) in the period 2006-2008. These studies correspond to a total potential capacity of 31,000MW. In 2007, Ibama, the environmental agency, gave approval for the construction of two new dams, the Jirau Dam (3,300 MW) and the Santo Antônio Dam (3,150 MW), on the Madeira River in the state of Rondônia. The bid for the Santo Antônio plant was awarded in December 2007 to Madeira Energy, with a 39% participation from state-owned Furnas, while the bid for the Jirau plant will be launched in May 2008. The government is also pursuing development of the controversial 11,000 MW Belo Monte Dam in the state of Pará, on the Xingu River. IBAMA approved Belo Monte's provisional environmental license in February 2010 despite internal uproar from technicians over incomplete data.
Also in 2007, Electronuclear was granted permission to resume construction of Angra 3, a 1,350 MW plant, and is currently in the process of selecting a site for a fourth nuclear power plant. In February 2014, Eletrobras Eletronuclear awarded contracts to begin construction, with an estimated completion date of 2018.
Currently, the development of gas-fired thermoelectric power is somewhat jeopardized by the lack of secure gas supplies. In fact, having a secure gas contract is a prerequisite to build a new thermoelectric plant and to participate in a new energy auction (See Energy auctions below). In order to counter the risk of unavailability of gas supplies, Brazil is in the initial stages of planning to build two LNG terminals that would likely come on-stream around 2010. However, in the meantime, several thermoelectric plants are converting their machinery to dual-fuel capacity (oil and gas).
Total electricity consumed in 2007 was 410 TWh, while annual consumption per capita for the same year averaged 2,166 kWh) (compare with 12,300 kWh per capita for the United States). The share of consumption by sector was as follows:
- Residential: 40% (including 6% for the rural sector)
- Industrial: 25%
- Commercial: 22%
- Rural: 6%
- Public: 13%
Electricity demand is expected to grow an average of 3.6% in the next few years, leading to total estimated consumption of 504 TWh and average per capita consumption of 2,527 kWh (around 18% of that of the United States and 45% of that in the United Kingdom).
Supply vs. demand
In Brazil, capacity addition traditionally lagged behind demand growth. Electricity demand is expected to continue to grow at a quick pace. The income elasticity of demand for electricity is estimated by Eletrobras at above unity. Between 1980 and 2000, electricity demand increased on average by 5.4 per cent per year while GDP grew by 2.4 per cent on average per year. Investment is therefore needed to boost generation and transmission capacity because there is limited excess supply, despite the reduction in demand following the energy rationing programme implemented in 2001 in response to the energy crisis.
Access to electricity
Brazil, together with Chile, is the country with the highest access rate in Latin America. The power sector in Brazil serves more than 50 million customers, which corresponds to about 97% of the country's households, who have access to reliable electricity.
Interruption frequency and duration
Interruption frequency and duration are very close to the averages for the LAC region. In 2005, the average number of interruptions per subscriber was 12.5, while duration of interruptions per subscriber was 16.5 hours. The weighted averages for LAC were 13 interruptions and 14 hours respectively.
Responsibilities in the Electricity Sector
Policy and Regulation
The Ministry of Energy and Mines (MME) has the overall responsibility for policy setting in the electricity sector while ANEEL, which is linked to the Ministry of Mines and Energy, is the Brazilian Electricity Regulatory Agency created in 1996 by Law 9427. ANEEL's function is to regulate and control the generation, transmission and distribution of power in compliance with the existing legislation and with the directives and policies dictated by the Central Government. The National Council for Energy Policies (CNPE), is an advisory body to the MME in charge of approving supply criteria and "structural" projects while the Electricity Industry Monitoring Committee (CMSE) monitors supply continuity and security.
ANEEL and the Ministry of Environment play almost no part in which investment projects go ahead, but they only influence how projects are executed once the decision has been taken. Both have had their bosses resign rather than supporting infrastructure projects in the Amazon.
The Operator of the National Electricity System (ONS) is a non-profit private entity created in August 1998 that is responsible for the coordination and control of the generation and transmission installations in the National Interconnected System (SIN). The ONS is under ANEEL's control and regulation.
The Power Commercialization Chamber (CCEE), successor of MAE (Mercado Atacadista de Energia Electrica), is the operator of the commercial market. The initial role of the operator was to create a single, integrated commercial electricity market, to be regulated under published rules. This role has become more active since now CCEE is in charge of the auction system. The rules and commercialization procedures that regulate CCEE's activities are approved by ANEEL.
Finally, the Power Research Company (EPE) was created in 2004 with the specific mission of developing an integrated long-term planning for the power sector in Brazil. Its mission is to carry out studies and research services in the planning of the energy sector in areas such as power, oil and natural gas and its derivates, coal, renewable energy resources and energy efficiency, among others. Its work serves as input for the planning and implementation of actions by the Ministry of Energy and Mines in the formulation of the national energy policy
The Brazilian electricity model is fully deregulated, which allows generators to sell all of their "assured energy" via freely negotiated contracts with consumers above 3MW or via energy auctions administered by CCEE (See energy auctions below). . Under this model, distributors are required to contract 100% of their expected demand. Currently, Brazilian generation supply can be sold under four types of markets:
- "Old energy"* auction contracts (long term): approximately 41% of the 2006 market
- "New energy"* auction contracts (long term):delivery starts in 2008
- Free-market contracts (long term): approximately 27% of 2006 market
- Spot Market Sales (size uncertain)
(*The government identifies two types of generation capacity, "old energy" and "new energy". Old energy represents existing plants that were already contracted in the 1990s, while new energy refers to that energy produced by plants that have not yet been built, or by existing plants that meet certain criteria.)
In Brazil, large government-controlled companies dominate the electricity sector. Federally owned Eletrobras holds about 40% of capacity (including 50% of the Itaipu dam), with state-companies CESP, Cemig and Copel controlling 8%, 7% and 5% of generation capacity respectively.
Generation capacity is shared among the different companies as follows:
|Company||Controlling shareholder||Installed capacity (MW)||% Total|
|Eletrobras (1)||Federal Gvt.||38,111||40%|
|CESP||SP State Gvt.||7,451||8%|
|Cemig||MG State Gvt.||6,692||7%|
|Copel||PR State Gvt.||4,550||5%|
|Tractebel Energia||GDF Suez||6,870||7%|
|AES Tiete||AES Corp.||2,651||3%|
|Others||Mostly private sector||29,969||31%|
Currently, about 27 percent of the generation assets are in the hands of private investors. Considering the plants under construction, as well as the concessions and licenses already granted by ANEEL, this figure is expected to grow up to 31 percent in the medium term and to reach almost 44 percent over 5–6 years. Private capital participation in the generation business will likely represent 50 percent of the installed capacity in the years to come
Brazil's transmission system is growing importance since adequate transmission capacity is essential to manage the effects regional droughts, allowing to move power from areas where rainfall is plentiful. As a matter of fact, the rationing that occurred in Brazil during 2001-2002 (See The 2001-2002 crisis below), could have largely been averted if there had been adequate transmission capacity between the south (excess supply) and the southeast (severe deficit).
Transmission has remained almost exclusively under government control through both federal (Eletrobras) and state companies (mainly Sao-Paulo-CTEEP, Minas Gerais-Cemig, and Parana-Copel) until recently.[when?] However, under the new sector regulatory model, there are about 40 transmission concessions in Brazil. Most of them are still controlled by the government, with subsidiaries under federal company Eletrobras holding 69% of total transmission lines.

In Brazil, there are 49 utilities with distribution concessions and about 64% of Brazilian distribution assets are controlled by private sector companies. The following table lists Brazil's most important distribution companies:

Renewable energy resources
Apart from biomass, which accounts for about 3.5% of total generation capacity, no other renewable energy source besides hydroelectricity plays a relevant role in the energy mix. However, the potential for wind energy, which is concentrated in the Northeast, is very large. It is about 143 GW, which exceeds current installed capacity and is second only to Argentina in the LAC region. There are projects for the development of biomass, solar and wind energy.
In 2002, the government of Brazil created a Program to Foster Alternative Sources of Electric Power (PROINFA). The program aims to increase the participation of wind power sources, biomass sources and small hydropower systems in the supply of the Brazilian grid system through Autonomous Independent Producers (PIA). The medium to long-term objective (i.e. 20 years) of the program is that the defined sources supply 15% of the annual market growth until they reach 10% of the nation's annual electric power demand/total consumption.
History of the electricity sector
The situation prior to the reforms: the state-dominated model
The power sector in Brazil was essentially in government's hands until the early 1990s. The sector had seen remarkable development in the 1970s. However, by the late 1980s, the state-ownership model was on the verge of collapse. This delicate situation was the result of heavily subsidized tariffs and a revenue shortfall in the sector of about US$35 billion, which led to the delay in the construction of about 15 large hydro plants due to lack of funds for investment. Efforts to address the deterioration of the sector were not successful, a situation that further intensified the need for deep reforms. A major commitment was made by President Cardoso to carry out a substantial reform of the Brazilian electricity sector. The first reforms introduced in the power sector were aimed to allow the participation of private capital and also to improve its economic situation.
The 1990s reforms
The Project for Restructuring the Brazilian Electric Sector, RESEB, which laid down the first steps for the implementation of the power sector reform, was initiated in 1996 during the administration of President Cardoso. The objective of the reform was to build a more competitive power sector with the creation of a level playing field for private sector participation. In addition, state-owned utilities and assets were privatized. Although transmission assets were not privatized, most of the expansion of the transmission network has been carried out by private capital. This reform also led to the creation, in 1996, of ANEEL (Brazil's National Electricity Regulatory Agency), a quasi-independent regulatory body in charge of overseeing the electricity sector. However, the main restructuring steps were taken with the enactment of the 1998 Law (Law 9648/98). Those steps included the creation of an independent operator of the national transmission system (ONS) and an operator of the commercial market (MAE), which did not become operational until 2001.
As a result of the reforms of the power sector, new capital was attracted, both in terms of privatization and greenfield projects. Some of the state-owned generation capacity was acquired by foreign investors such as Tractebel, AES, Prisma Energy, El Paso and Duke, which became significant producers. In addition, local investors such as industrial groups, large customers, utilities and pension funds also invested heavily in the national generation sector. Other companies such as EdF (Électricité de France), Endesa and Chilectra focused on the distribution segment, a segment in which privatization brought improved quality of service and a reduction of theft, non-payments and technical losses.
However, the reforms were not successful in preventing the energy crisis that was to unfold in 2001. Installed capacity expanded by only 28 per cent during 1990-99, whereas electricity demand increased by 45 per cent. In 1999, as the power shortage was already foreseen, the President Cardoso Administration made efforts to increase private investment in the electricity sector through a Priority Thermal Power Program (PPT) that aimed at the expeditious construction of more than 40 gas-fired thermal plants. Unfortunately, the needed investment did not materialize and the crisis became unavoidable.
The 2001-2002 crisis and the government's response
Brazil was faced with one of the most serious energy crises in its history in 2001-2002. The crisis was the direct result of a sequence of a few years drier than average in a country with over 80% of hydroelectric generation capacity. Additionally, several delays in the commissioning of new generation plants and transmission problems in the third circuit from the Itaipu hydropower plant accounted for a third of the energy deficit. Reservoir levels reached such low levels that supply could not be ensured for more than four months.
It was soon clear that strict demand reduction programs would be needed to avoid widespread blackouts. In June 2001, the government created the Crisis Management Board (CGE), chaired by President Cardoso himself. The CGE received special powers among which was the authority to set up special tariffs, implement compulsory rationing and blackouts, and bypass normal bidding procedures of the purchase of new plant equipment. Instead of resorting to rolling blackouts, the government chose to apply a quota system. Quotas were established for all the consumers based on historical and target consumption level, applying bonuses for consumption well below the prescribed level, penalties for over-consumption and some freedom for the large users to trade their quotas in a secondary market. The government's goal of reducing historical consumption levels by at least 20% for an eight-month period was successfully achieved, with the government having to pay over US$200 million in bonuses to residential, industrial, and commercial customers. This achievement allowed the system to overcome that long period without blackouts and brownouts and proved the potential of demand-side management and energy efficiency efforts, which were able to create a virtual capacity of 4,000MW, helping the country to bridge the supply demand gap in a very economic way. In addition, the government launched a program for contracting emergency generation capacity, with bids for a total of 2,100MW of new thermal capacity accepted.
However, the crisis affected numerous actors. Generators and distributors experienced a 20% reduction in their revenues due to the contraction in consumption. This situation was eventually addressed by an increase of tariffs approved by the government. The financial situation of distributors was also damaged, with customers also suffering from the increase in electricity prices (140% in nominal terms between 1995 and 2002).
The 2003-2004 reforms: energy auctions
In January 2003, the new administration led by Luiz Inácio Lula da Silva took over among criticism of the reforms introduced in the electricity sector by the administration of President Cardoso, supporting a model in which the system should be fully regulated. The pending privatizations of three generation subsidiaries of the large state-owned utility, Eletrobras, were stopped. However, despite initial expectations, the new administration opted for a model that clearly aims to attract long-term private investment to the sector and that heavily relies on competition. In addition, the existing institutions were preserved and in some cases strengthened, with a new company, EPE, created with the specific mission of developing an integrated long-term planning for the power sector in Brazil.
The new legislative framework was defined by Law 10,848/2004, which established clear, stable and transparent rules aimed at ensuring supply and the continuous expansions of the intrinsic sector activities (generation, transmission and distribution). The expansion was linked to a fair return on investments and to universal service access, together with tariff adjustments. Decree 5,081/2004 approved the regulatory framework for the power sector, specifying specific provisions to achieve the objectives of the reform.  One of the defining elements of the model adopted by the new administration is the establishment of energy auctions as the main procurement mechanism for distribution companies to acquire energy to serve their captive consumers. This initiative assisted in the introduction of competition in the power sector and also helped to address some of the existing market imperfections. Under this system, auctions of capacity from new generation projects will be held three to five years in advance of delivery dates. The Ministry of Mines and Energy wants to ensure that the totality of future expansion needs is met and that plants are only built once they have won bids in energy auctions and are guaranteed long-term contracts. The first auction was held in December 2004, with contracts for a total of about 40GW traded.
Tariffs and Subsidies
Average electricity tariffs for the different sectors in 2007 were as follows:
Investment and financing
In the last 20 years, Brazil has been one of the main recipients of private capital investment in its power sector. Total investment by private actors in the power sector between 1994 and 2006 amounted to US$56,586 million in 124 projects. However, despite Brazil's deregulation and higher tariffs in the "new energy" auction system, investment, particularly in generation, has slowed significantly. This situation is not considered to be the result of concerns about the regulatory model or auction pricing caps, but it reflects the lack of available projects. The existing delays in granting environmental licenses and the uncertainties on the Bolivian gas supply, explain to a great extent the lack of hydroelectric and gas-fired thermoelectric projects respectively.
The investment required in power generation over the next 10 years is R$40 billion or around US$24.2 billion (April 29, 2008). This high investment will only be realized if the government succeeds in attracting greater private-sector investment.
Summary of private participation in the electricity sector
In Brazil, large government-controlled companies dominate the electricity sector. Federally owned Eletrobras holds about 40% of capacity (including 50% of Itaipu), with state-companies CESP, Cemig and Copel controlling 8%, 7% and 5% of generation capacity respectively. About 27% of generation assets are currently in the hands of private investors.
Transmission, it has remained almost exclusively under government control through both federal (Eletrobras) and state companies (mainly Sao-Paulo-CTEEP, Minas Gerais-Cemig, and Parana-Copel) until recently.[when?] However, under the new sector regulatory model, there are about 40 transmission As for distribution, there are 49 utilities with distribution concessions and about 64% of distribution assets are controlled by private sector companies.

Electricity and the environment
Responsibility for the environment
The Ministry of the Environment holds the environmental responsibilities in Brazil. One of its associated institutions is Ibama, the Brazilian Institute for the Environment and Renewable Natural Resources, which is in charge of executing the environmental policies dictated by the Ministry regarding environmental licensing; environmental quality control; authorization of the use of natural resources; and environmental monitoring and control among others.
Greenhouse Gas Emissions
OLADE (Latin American Energy Association) estimated that CO2 emissions from electricity production in 2003 were 20 million tons of CO2, which corresponds to less than 7% of total emissions from the energy sector. This low contribution to emissions from electricity production in comparison with other countries in the region is due to the high share of hydroelectric generation.
CDM projects in electricity
Brazil is host to the largest number of CDM projects in the Latin America region. Registered projects represent 40% of the total in the region and account for 45% of Certified Emission Reductions (CERs) (up to 2012).
As for the power sector, there were 91 projects registered in March 2008, adding up to an estimated total of 9 million tons of CO2 per year. The distribution of projects by category is as follows:
|Project type||Number of projects||ktonCO2/year|
|Energy efficiency industry||1||49|
|Energy efficiency own generation||1||90|
|Fossil fuel switch||6||139|
Energy Costing of Brazilian Electricity
An exergoeconomic assessment accounting for the total and non-renewable unit exergy costs and specific CO2 emissions of Brazilian electricity is performed by Flórez-Orrego et al. (2014), comprising thermal, nuclear, hydro, wind farms and biomass-fired power plants. The analysis starts from the fuel obtainment and continues through the different stages of construction, fuel transportation and processing, operation and decommissioning of the plant, with electricity generation as the desired output. This approach allows the calculation of direct CO2 emissions as well as the upstream and downstream emissions, which play an important role in some technologies. In this way, a better comparison between the utilization of different fuels in the electricity generation can be achieved. An iterative calculation procedure is used to determine the unit exergy costs of electricity and processed fuels, since both electricity and processed fuel are used in their own production routes.
As it was expected, fossil-fired power plants presents the highest specific CO2 emissions, with the coal-fired power plants leading the group. However, even though fossil-fired power plants presents the most marked environmental impacts, their total unit exergy costs are much lower than that presented by sugar cane bagasse-fired power plants. This shows that, although almost renewable, the typical configurations of sugar cane bagasse-fired power plants are far from being efficient technologies. Hydro and wind farms present the lowest specific CO2 emissions as well as the lowest unit exergy cost. Due to the high participation of renewable sources in the production of electricity (near to 89% of the total), Brazilian electricity mix emissions are found to be 7.5 and 11.8 times lower than Europe and World electricity mixes. Also, owed to the higher efficiency of hydroelectric power plants, which contribute to the major part of the electricity generation in Brazil, the total unit exergy cost is lower, and thus, exergy efficiency of electricity generation is higher if compared with countries based on fossil fuels for electricity generation.
Apparently, total exergy cost of wind and natural-gas fired technologies are almost the same, but contrarily to the wind power plants, the non-renewable unit exergy costs of NG-fired power plants is practically equal to the total cost. It should be noted that this result is a consequence of the efficiency assumed for wind power plants. If energy storage is to be taken into account for intermittent technologies such as wind farms, the total exergy cost could be slightly increased. The upstream and downstream CO2 emissions in the coal route represent a very small part of the total CO2 emissions, if compared with the direct emissions of coal burning in the power plant. Finally, it is pointed out that controversies related to the flooding dams of vast zones with complex ecosystems should be carefully analysed since, according to the results reported by Dones et al., the GHG emissions could be increased up to achieve emission levels comparable to those of gas combined cycles power plants.
Inter-American Development Bank
The Inter-American Development Bank (IDB) is currently (April 2008) supporting several projects and contributing to various technical assistance initiatives in the power sector in Brazil. The most relevant projects with financing from the IDB are:
- The The Renewable Energy Service Delivery Project is a technical cooperation that seeks to implement several pilot projects that demonstrate three promising, private-sector-led business models to provide renewable energy services to isolated communities in Brazil. The IDB supports this US$45 million technical assistance with US$2.25 million.
- The Celpa Capital Investment Program aims to expand and improve Celpa's distribution electrical system allowing the Company to (i) provide electricity to new customers mostly in rural areas; (ii) allow productivity gains and reduce costs and (iii) improve quality and reliability of its network distribution. The IDB supports this US$400 million project with a US$75 million loan.
- In February 2008, the IDB approved a US$95.5 million loan for the ATE III Transmission Project, a US$402 million project for the development, construction, erection, commissioning, operation and maintenance of approximately 459-kilometer transmission lines from the State of Pará to the State of Tocantins.
The World Bank is currently (April 2008) supporting three rural poverty reduction projects that include the provision of access to electricity services:
- Rural Poverty Reduction Project in Pernambuco: US$60 million loan (10% electricity component)
- Rural Poverty Reduction Project in the State of Ceara: US$50 million loan (10% electricity component)
- Bahia State Integrated Project – Rural Poverty: US$54.35 million (16% electricity component)
