The Renewable Energy Law Review: Brazil


Brazil's power generation already originates predominantly from renewable sources. Hydropower accounts for 61 per cent of the national installed capacity, with a total of 109GW currently in operation.2

This scenario creates the necessity for diversification of energy sources, because the level of domination currently exerted by hydroelectric plants, unfortunately, also has its shortcomings. Droughts, when combined with the lack of sufficient alternative energy sources, have led to surges in energy spot prices in the recent past, as occurred in 2013 and 2014, when a financial crisis, known as the generation scaling factor dispute, affected all hydro generators and has not been completely resolved to date.

Indeed, for the second half of 2021, the system operator is expected to constantly make use of thermoelectric power generation dispatches and there is even a risk that power rationing measures will be put in place in some regions to deal with the very low levels of hydroelectric reservoirs.

On top of that, potential hydroelectric sites are becoming scarcer and further away from the consumption market, mostly in the Amazon, where potential environmental impacts, when not preventing the development of new projects altogether, mean plants do not fully benefit from sites' power output capabilities. At present, for instance, large projects recently completed in the region, such as Belo Monte (11,233MW), were designed as run-of-river plants, which have small reservoirs to limit environmental impact, but on the other hand have a much lower power output than they would have if they had larger dams, and their ability to save water for drier seasons is limited.

Non-hydro renewable sources have become more representative in recent years, with wind corresponding to 38 per cent and solar to 19 per cent of the installed capacity currently under construction, while conventional hydropower plants under construction represent 1 per cent.3 That trend is set to continue in the future.

The year in review

The Brazilian renewables sector continues to attract new investment at a healthy pace, despite the small GDP growth rates the country has faced since 2014. One reason for this is, in part, the fact that Brazil is geographically gifted when it comes to renewable sources of energy, and it is a jurisdiction that is very open to foreign investment.

The following announcements and transactions illustrate the continued attractiveness of the Brazilian renewable sector:

  1. After divesting from the distribution business in Brazil through the sale of AES Eletropaulo and AES Sul, AES has expanded heavily into renewables, with the acquisition of wind power complex Alto Sertao 2 (600 million reais) from Renova Energy and a 1.1GW greenfield pipeline of wind projects in Rio Grande do Norte being the most significant acquisitions to date.4
  2. International Big Oil companies such as Shell, Equinor and BP have started looking and buying into renewables. Equinor has entered into a joint venture with fellow Norwegian company Scatec Solar for the development of the 162MW Apodi solar cluster and other new solar generation projects, and has formed a joint venture with Micropower Comerc to develop power storage projects.5
  3. Atlas Renewable Energy continues to establish a strong presence in the solar power generation sector, having obtained a US$67 million loan to build solar plants in north-eastern Brazil, to supply energy under a 15-year power purchase agreement (PPA) with Dow Chemicals. The transaction is considered as one of the first financings for a Brazilian solar project made solely in US$. Despite the relatively small size of the transaction, it is quite innovative in that the long-term PPA is also denominated in foreign currency.
  4. Electric Energy Commercialisation Chamber (CCEE), a private, non-profit clearing house for the Brazilian electricity sector, obtained a 15.3 billion reais loan from a syndicate led by BNDES, the Brazilian state-owned development bank, to launch a financial support scheme for Brazil's electricity sector amid the covid-19 crisis. The support scheme was designed to support the stability of the sector by providing greater liquidity to Brazilian power distribution companies, which are facing financial strain amid the covid-19 pandemic, with an estimated average 6.3 per cent loss in revenue in the sector since the coronavirus outbreak.
  5. In addition to the above, currently in progress is the privatisation of Eletrobras, the largest electricity company in Latin America (and the 16th largest company in the world), responsible for approximately 31 per cent of generating capacity, 47 per cent of transmission and 7 per cent of electricity distribution in Brazil. The proposal aims at reducing the Brazilian Union's participation in the capital of Eletrobras, with its consequent democratisation in the Stock Exchange.6
  6. Also, there are changes in law being discussed in the Brazilian congress that may facilitate international lending to purely domestic transactions, by expanding the list of cases where contracts between Brazilian entities can be linked to foreign currency (currently, there are restrictions that severely limit foreign currency transactions in the domestic market).
  7. Other than the foregoing, traditional members of the market, such as Omega Energia, Cobra, Atlantic Renováveis, CPFL Renováveis continue to thrive with new wind and solar power generation projects.

Three new energy auctions (A-3, A-4 and A-5 auctions, please see the explanation for the terminology in Section III.ii) are scheduled for the second half of 20217 and are expected to provide another boost for new utility scale wind and solar power generation projects.

The policy and regulatory framework

i The policy background

The Brazilian power sector as a whole (including the renewable power generation industry) has the fundamental characteristic of being centrally planned. Therefore, the government and regulators exert great influence on how the market develops. For example, governmental and regulatory bodies will guide generation expansion by determining what new energy auctions will be carried out and what price caps will apply, and what new transmission facilities shall be put up for tender and constructed (expansion of generation in Brazil relies heavily on pari passu expansion of the transmission grid capacity).

In addition to the centralised planning of the power sector, governmental incentives such as subsidised grid tariffs and tax exemptions on energy transactions or equipment (see Section III.ii on incentives) have been very important, if not crucial, to make renewable sources of power competitive in Brazil.

ii The regulatory framework

Institutional bodies and agents

The following are the relevant institutions in the Brazilian power sector:

  1. Ministry for Mines and Energy (MME) – the government body responsible for basic policies and decisions, including setting and definition of basic conditions for new energy auctions and concession bids.
  2. National Electric Energy Agency (ANEEL) – the independent agency in charge of sector-wide regulation, preparation of new energy auction tender rules and PPAs, definition of grid tariffs, overseeing of concession agreements and generation authorisations, enforcement of regulatory compliance and imposition of penalties and other disciplinary actions.
  3. National System Operator (ONS) – the independent system operator responsible for the operation and management of the national grid (save for some regions in the Amazon, Brazil is nationally interconnected) and for the enactment and enforcement of the grid procedures, including assessing interconnection feasibility of power generation projects.
  4. Electric Energy Commercialisation Chamber (CCEE) – the power market is organised by CCEE, which acts as the administrator of both the new energy auctions and the spot market (and, like ONS, it is a private entity formed and governed by power sector companies and regulated by ANEEL). CCEE measures aggregated consumption and generation on a real-time basis, keeps the market accounts and settles the spot market transactions.
  5. Energy Research Company (EPE) – a state-owned company attached to MME responsible for the definition of transmission and generation expansion plans, and the definition and setting of technical requirements to be met by projects to qualify for new energy auctions.

Permitting and development road map

Power generation authorisation

While hydroelectric power generation with capacity over 50MW, transmission and distribution activities are subject to concession agreements,8 hydropower generation under 50MW (small hydroelectric plants (PCHs)) and non-hydropower generation of any installed capacity (including solar, wind, gas, biomass and thermal sources in general) are subject to authorisations.9

Concessions are more heavily regulated than authorisations and assets as a matter of course revert to the government at the end of the concession.10 Concessions and authorisations may have terms of up to 30 years and are renewable at the government's discretion.11

The regulatory playing field for renewable energy generators is stable and there have been no significant changes to the fundamentals of the industry in the recent past.

For projects selling power in new energy auctions, the power generation authorisation is granted by MME, while ANEEL is the entity that grants authorisations for projects developed to operate in the free energy market (the structure of the power market is discussed further below).

Environmental licences

Brazil has strict environmental legislation, making the development of a generation project subject to a threefold licensing process:12 from greenfield to commercial operation, a project must apply and fulfil the applicable requirements for the issuance of:

  1. a provisional licence, which will allow the entrepreneur to continue the development of the project and demonstrate, when required (in power auctions, for instance), that the project is viable from an environmental standpoint;
  2. an installation licence, which will authorise the construction of the generation project; and
  3. an operational licence authorising the commercial operation of the power plant.
Other permits

Depending on the characteristics of the project and the location, other permits may be required, such as airspace permits (if the project is located inside or near areas where air traffic safety is a concern), mining blockages (if the project is within the boundaries of an area of mining rights held by third parties) and designations of public utility, to enforce the creation of rights-of-way for transmission lines (where the project company is unable to agree amicable terms with neighbouring landowners).

Energy markets

Power commercialisation in Brazil is structured into two main market environments: a regulated environment and a free-market environment.13

The power market as a whole is organised by CCEE. Energy prices are defined under free-market conditions: in the regulated market, generators sell their power at auction to distributors for the prices they find suitable; and, in the free market, generators will enter into freely negotiated agreements. Only distribution and transmission tariffs are fixed by ANEEL.

Prices in PPAs are, in general, subject to annual adjustments for inflation. Auction PPAs include conditions allowing prices to be reviewed should new taxation or legislation impact energy prices. Parties are free to negotiate conditions for the revision of prices in free market PPAs.

Regulated PPAs

The regulated market is based on power auctions where, as a rule, greenfield generation projects sell power for future delivery (new energy auctions, known as A-3 and A-5 auctions respectively, are carried out three or five years ahead of the date that delivery of energy is supposed to commence), by way of PPAs with terms ranging from 15 to 25 years, resulting from auctions jointly conducted by ANEEL, EPE and CCEE. The government may also, at its discretion, call auctions for generators that are already operating (non-greenfield).

In the regulated environment, energy is purchased either by a pool of distributors or, when the auction is for 'reserve-energy' agreements, by CCEE. The auctions group generators together on the selling side, competing against each other on price to sell their energy to the pool of distributors. Distributors are, by law, allowed to purchase energy solely in the regulated environment, except for 10 per cent of their energy demand, which can be purchased in the free market from distributed generation plants (small generators connected to the distributors' own grid).

The amount of power needed by the pool of distributors remains secret until the end of the auction. The bids shall be no higher than a ceiling price defined by MME. The bid, from a generator, takes the form of the power output capacity submitted by the generator for the purposes of enrolment in the auction process together with the price at which that power is offered by the generator (but selection is based on price alone). It is immaterial whether a certain amount of power is supplied by two big projects or by 20 smaller projects.

To be eligible to participate in a regulated market auction, a generation project must be subject to a technical qualification process beforehand, which is carried out by EPE. Ordinance No. 21/2008, from MME, stipulates the following requirements for technical qualification of a generation project:

  1. registration of the project with ANEEL: this registration has the purpose of informing ANEEL that the entrepreneur is developing a power generation project and authorising the entrepreneur to take all measures needed before third parties, such as filing for environmental licences, access opinions, etc.;
  2. the expected schedule of construction works, including deadlines for the issuance of the relevant environmental licences, connection to grid, tests on completion and commercial operation of the power plant;
  3. a descriptive memorandum containing a comprehensive technical, economic and environmental description of the project;
  4. the project budget;
  5. documentation proving the entrepreneur has secured rights to the land for the construction and operation of the project (except for PCHs, which are entitled to the expropriation of lands for the reservoir and the power plant);
  6. certification of wind measurements and of estimated annual energy output of wind projects, issued by an independent certifying entity;
  7. the access opinion;
  8. water permits, for PCHs and thermoelectric plants;
  9. the environmental licences applicable to the project;
  10. the environmental studies produced for the environmental licence application;
  11. for thermoelectric plants (such as biomass and biogas), evidence of the plant's ability to store sufficient combustibles for continuous operation at nominal capacity;
  12. for PCHs, the basic design of the plant or the plant upgrade or refurbishment project approved by ANEEL;
  13. for solar projects, the certification of the solarimetric data, issued by an independent certifying entity; and
  14. for wind projects, a statement that the turbines to be deployed will be new.

Once a project has been declared technically qualified by EPE, it will be allowed to participate in the regulated market auctions. An entity participating in the auctions must meet certain legal, tax and financial requirements set out in the applicable auction's public request for proposals, such as a minimum net worth corresponding to 10 per cent of the project's budget and the requirement to present a bid bond in an amount corresponding to 2.5 per cent of the total investment required for the project (if successful in the auction, a performance bond corresponding to 10 per cent of this amount must be delivered to replace the bid bond).

If a project is successful in selling energy in the auction, MME will issue a generation authorisation and construction must start. If an entrepreneur manages to finish a project ahead of the date on which energy supply is supposed to start, it can sell the energy generated before that date in the free market.

If the construction of a project is not concluded on time, the generator must purchase power in the free market to fulfil its obligations under the PPA. In that case, however, the generator will receive payments calculated in accordance with whichever of the following prices is lower:

  1. the PPA price (or 85 per cent thereof if delivery is delayed for more than three months);
  2. a combination of the average energy spot price and a spread calculated pursuant to ANEEL's regulations; or
  3. the actual price set out in the free-market agreement concluded by the generator.14
Free market

Generators, commercialisation agents and free consumers can trade power in the free-market environment, under freedom-of-contract conditions. The free market represents nearly 30 per cent of the total amount of commercialised energy in Brazil.

Free-market PPAs do not require prior approval from ANEEL or MME, nor to be registered with any of those authorities. Parties to the PPA must, however, provide information concerning amounts of energy and period of supply in CCEE's electronic system, in time for the agreement to be used to settle the energy market. Both CCEE and ANEEL have the authority to request copies of PPAs for inspection purposes.

In contrast to auction PPAs, free-market agreements tend to be for the short to mid term, and free-market PPAs with terms longer than five years are relatively rare. Because of the absence of a secure long-term revenue stream for free-market PPAs, it is more difficult to structure project finance financing mechanisms than it is for projects selling energy via auction PPAs, which have a guaranteed long-term revenue stream.

Free consumers are qualified as follows:

  1. special free consumers: consumers with a contracted load of 0.5MW, if they can purchase power from renewable sources only; and
  2. free consumers: consumers with a contracted load of 3MW (MME recently issued an ordinance reducing the load requirement to 2.5MW as of 1 July 2019 and to 2MW as of 1 January 2020).15


Special new energy auctions

As mentioned above, MME and ANEEL may conduct energy auctions specifically for renewable generation or alternative sources, creating demand for long-term PPAs (20–25 years) for renewable projects. Historically, at least one auction for renewables has been carried out each year.

At the beginning of the development of non-hydro renewables in Brazil, special auctions were required specifically for those sources because they could not compete with conventional energy sources. However, as the market has evolved, wind and solar have become competitive sources of power and have started to compete against conventional energy in energy auctions.

For 2019, two auctions were planned for wind, solar, hydroelectric and thermoelectric sources: A-6 and A-4 auctions.

Subsidised grid tariffs

Generators of renewable sources (hydro, biomass, biogas, wind, solar and qualified cogeneration) injecting up to 300MW of power into the grid, as well as consumers purchasing power from those generators, are entitled to a 50 per cent discount on grid use tariffs.16 This incentive plays a big role in fostering investments in renewables in Brazil and has helped to create a big share for 'incentivised energy' in the Brazilian energy free market.

This incentive does not apply to distributed generation.

Law No. 14,120/2021, of 3 March 2021, has determined that renewable power generation projects shall no longer be entitled to the discount on grid tariffs. Certain transition rules are in place, though:

  1. for operational projects, the benefit shall continue to apply for the first term of the relevant power generation authorisation (usually 35 years);
  2. the discount shall still apply for new projects or capacity increases, but only for projects that obtain the relevant power generation authorisation up to 31 August and start commercial operations within 48 as of the date of the authorisation; and
  3. a 50 per cent discount shall continue to apply for a period of 5 years as of 1 September 2020, and a discount of 25 per cent shall continue to apply for a period of 5 years thereafter, for new small hydroelectric power generation projects (up to 30MW installed capacity).

The new law has originated from a widespread view that renewable power generation projects (especially solar and wind) have become competitive alternatives and no longer require grid tariff subsidies in order to be economically feasible. As a matter of fact, solar and wind have become so competitive that only a few small hydro projects have been able to win new energy auctions in the last 5 years.

In order to make up for the termination of the grid tariff subsidies, the federal government must, within 12 months of 1 September 2020, establish directives for the creation of new mechanisms or markets considering the environmental attributes of new renewable energy projects. Expectations are that Brazil may have organised markets for 'green energy certificates', 'emissions reductions certificates' and green bonds arrangements in the foreseeable future.17

ICMS and PIS/COFINS exemption on distributed generation output

The amount of power supplied by distribution companies to consumers corresponding to the amount of power injected into the grid by distributed generation projects is exempt from ICMS (a Brazilian tax similar to VAT). The exemption was allowed by CONFAZ ICMS Agreement No. 16/2015 and replicated by the legislation of most states. ICMS is a state tax and rates normally vary between 12 per cent and 20 per cent depending on the state and type of consumer.18 The ICMS exemption on off-site distributed generation (when the power plant and consumption facilities are not located in the same place) applies differently according to the legislation in each state.

Similarly, the amount of power supplied is exempt from the PIS/COFINS federal taxes.19 The PIS/COFINS rate is 9.25 per cent.

If it were not for the exemptions, the taxes would apply to the invoices issued by power distribution companies to consumers using the distributed generation net metering scheme.

ICMS exemption on equipment

Pursuant to CONFAZ ICMS Agreement No. 101/97, as amended, equipment for wind and photovoltaic power generation is ICMS exempt.

Some photovoltaic equipment, such as inverters and trackers, however, has not been covered by the exemption.

Tax reduction for infrastructure development

Under Law No. 11,488/2007, renewable power generation projects are entitled to PIS/COFINS exemption on equipment, materials and services to be accounted as fixed assets of the project.

To become entitled to tax reduction for infrastructure development (known as REIDI), the project must have received a power generation authorisation and have applied to be qualified as a priority project, which is normally granted by ANEEL.

Incentivised project bonds

Projects declared a priority by ANEEL (see above) are also entitled to issue incentivised project bonds (also known as green debentures).

Law No. 12,431/2011 governs incentivised project bonds. Individuals holding these bonds are exempt from income tax, and legal entity bondholders pay income tax at a 15 per cent rate. The bonds must have a maturity of at least four years and pay interest at intervals no longer than 180 days.

Renewable energy project development

i Project finance transaction structures

Because of the complexity of renewable energy projects, their high structuring costs and long implementation periods, project finance is the preferred funding mechanism in Brazil. Most renewable energy projects are currently being developed in the context of energy auctions where regulated PPAs represent the main source of revenues. In light of that, the ability to secure long-term contracts that offer predictable cash flows makes renewable energy projects especially well-suited to project financing.

Diverse loan structures are commonly used for project finance in Brazil (some of them very similar to international practice, such as direct loans and syndicated loans, with administrative and security agents, intercreditor agreements and guarantee sharing agreements), including limited-recourse loans (i.e., loans secured by the project assets and paid entirely from the project cash flow), rather than from the general assets or creditworthiness of the project sponsors.

The ownership structures commonly used in Brazilian project financings for renewable energy projects usually involves equity investors (known as sponsors) and debt providers that advance loans to the project company, a special purpose vehicle incorporated for the exclusive purpose of owning and exploiting a certain project. BNDES, the Brazilian state-owned development bank, has always played a major role in the financing of large projects. In addition to BNDES, Banco do Nordeste do Brasil,20 state-owned banks and funds such as Banco do Brasil, Caixa Econômica Federal and FI-FGTS,21 as well as some Brazilian and international commercial and investment banks, have also been very active in the financing of projects in Brazil.

BNDES, which has traditionally been the key lender to the infrastructure sector in Brazil, has changed its strategy and now offers rates that are closer to market rates. This creates an opportunity for commercial banks (national and foreign) and capital markets to assume increasing importance in long-term financing of infrastructure. In this context, infrastructure bonds are increasingly used to finance projects in Brazil and, when issued in connection with the financing of power projects, they may benefit from tax incentives (see Section III.ii).

Official interest rates (SELIC, created in 1996) are currently at their lowest level in the history of this index, and the renewables industry project finance is expected to pick up pace when the Brazilian economy starts to recover from the covid-19 pandemic. Despite the interruptions caused by the covid-19 pandemic, according to the Brazilian Ministry of Finance, in 2020 the issuance of such bonds surpassed BNDES disbursements for the first time.

ii Distributed and residential renewable energy

Since May 2012, Brazil has implemented the regulatory framework for the operation of mini (up to 75kW) and micro (between 76kW and 5000kW) distributed generation from solar, wind, hydro, biomass or qualified cogeneration sources, along with a net metering scheme allowing end users to inject power into the grid and offset energy bill costs.22

Following a slow start, and a revision of the legislation,23 the distributed generation market has grown exponentially. Brazil now has 502,888 distributed generation projects – comprising 502,473 solar, 312 thermoelectric, 34 mini hydro and 69 wind power projects with a total 6GW installed capacity and 612,929 consumers making use of the distributed generation net metering scheme.24

The scope of the net metering arrangement for distributed generation has been heavily criticised and is expected to be addressed by the prospective revision of Resolution ANEEL No. 482/2012 (originally due by 31 December 2019) (see Section IV.ii). Currently, consumers generating energy off site are entitled to use the power delivered into the distribution grid to offset both energy and grid tariffs, despite using the grid for purposes of energy consumption. This has been viewed as a crossed subsidy (i.e., paid for by consumers that do not necessarily benefit from this arrangement), as the tariffs that power distribution companies charge all their clients are increased to make up for losses of revenue because of the net metering mechanism.

The market expectation is that net metering will be reduced solely to offset energy tariffs, and not grid tariffs. Because grid tariffs are the main component in energy supply costs, the economic gains from the use of distributed generation will be substantially reduced if only energy tariffs are allowed to be offset.

The matter has been the subject of convoluted regulatory and political discussion, which has delayed the publication of the amended regulation by ANEEL (in fact, the amendment has still to be published at the time of writing and a new bill of law making the distributed generation incentives mandatory is under discussion in the national congress).

iii Non-project finance development

Renewable energy projects also attract private equity firms, pension funds, investment funds, insurance companies and family offices seeking higher yields, and these provide much-welcomed funding alternatives for the industry.

Another notable trend is the reinvestment of merger and acquisition proceeds by existing participants in new projects. EDP Renováveis (EDPR) of the Portuguese group EDP recently sold its equity share in a 137MW operational wind farm project named Babilônia, located in Bahia state to a subsidiary of private equity investor Actis, for a total of 650 million reais.25 This sale is part of EDPR's capital recycling strategy, consisting of the sale of majority stakes in operational and development projects, allowing EDP to reinvest in accretive growth opportunities.26 Around the same time, BNDES approved funding of 1 billion reais for the construction and implementation of six 319.2MW wind farms and an associated substation by EDR, located in Rio Grande do Norte,27 confirming the trend for reinvesting proceeds in new projects.

Renewable energy manufacturing

Brazil has a long-established chain of supply for conventional (hydro and thermoelectric) renewable sources, with the presence of suppliers of all sizes, both domestic and international.

Mainly because of national content requirements under the PROINFA renewables incentive programme (which helped to start the wind power industry in Brazil in 2004) and the BNDES financing programme, a complete chain of supply for wind power projects has been developed in Brazil. Enercon (known as Wobben in Brazil), Siemens Gamesa and General Electric were the first companies to set up manufacturing facilities, followed by Vestas and Suzlon, among others. In addition to the major turbine manufacturers, Brazil has a myriad of suppliers of components, including for towers, blades and cast metal parts.

For photovoltaic equipment, there is a similar trend, with significant manufacturers such as BYD and Canadian Solar having established local facilities.

Conclusions and outlook

As regards the volumes contracted solely through regulated auctions, 2.5GW of additional solar generation capacity is about to be constructed and start operation by 202228 and 5.2GW of additional wind capacity shall be operational by 2023,29 creating substantial demand for equipment, financing and services.

A new regulatory reform is expected for 2022, aiming at ensuring that the metrics and mechanisms currently in use are adapted to expand the power sector to meet the ever-increasing demand for energy in Brazil at an adequate pace to assure supply; and adjusting the 'architecture of economic signals' for new investments and better allocation of resources, to improve economic efficiency. The new legislation shall consider such matters as:

  1. expansion of the free market;
  2. bankability of the power sector (beyond subsidised development bank financing);
  3. introduction of new technologies (energy storage, reversible hydroelectric plants, hybrid plants, etc.);
  4. better coordination of the expansion of transmission in relation to generation systems;
  5. distributed energy resources;
  6. new nuclear power generation projects;
  7. alternative ways for the commercialisation of the power generated by Itaipu;
  8. new forms of centralised power generation dispatch from ONS; and
  9. decommissioning and retrofitting plants.
