6. Incentives for Renewable Energies
• Renewable sources, such as small hydros, wind, biomass, waste and solar plants with
installed capacity up to 30 MW receive public incentives
• Long-term contracts are granted to incentivized energy generators through specific
energy auctions
• Renewable energy generators and free consumers that acquire incentivized energy are
entitled to a discount (ranging from 50% to 100%) in their tariffs for the use of distribution
network
• No concession or bid process required, just an authorization from Regulatory Agency
(ANEEL)
• Tax exemption
• Special credit facilities (BNDES)
