BRAZILIAN POWER SYSTEM
Thermal power plantHydro power plant
Hydroelectric share:
90% of 85,000 MW
96 Hydropower plants > 30 MW
57 Regulating reservoirs
Hydropower plants and regulating
reservoirs in the same river basin
are owned by different companies
Country is interconnected by 80,000
km of high-voltage lines
Centralized energy dispatch

FIRST POWER SECTOR REFORM (1996)
Rationale:– Public sector had no $ to invest
– Promote economical efficiency
Guidelines:– Private investment and competition in energy
generation and retailing
– Transmission and distribution would remain regulated, with provisions for open access
– Short-term energy prices would provide the signals for new investment

Reforms based on the same principles had worked in countries based on thermal production.
Would it work in a country like Brazil, based on hydro?

Problem: spot prices are usually too low; when they increase sharply, it is too late for new investments

The reform process failed to provide the required incentive for the construction of additional generation capacity
(Partly) because of this market failure, the country faced a severe rationing in 2001-2002
20% reduction on overall electricity consumption, for nine months

SECOND POWER SECTOR REFORM (2004)
• Under the new regulation, distribution companies contract new capacity five years in advance, through a public auction scheme:
– 20-year contracts are offered
– Selection is based on smallest tariff
• The awarded contract gives security to investors and serves as a guarantee for the project finance
• In the coming months, electricity produced by existing hydro power plants (~55,000 MW) will be auctioned

ENVIRONMENTAL MANAGEMENT
Concern: The social and environmental impacts caused by large hydroelectric projects implemented in the 70s and 80s. What’s new?
Methodology to screen out, at the river basin scale, the sites for construction of hydroelectric power plants which would not be social or environmentally feasible.
15
ENVIRONMENTAL MANAGEMENT
• Brazil needs to ensure a sustainable growth of energy supply.
• Hydroelectricity cannot be spared.
• The strategy is to select a set of sites that would cause minimum environmental and social impacts.
• However, we are not seeking for a set that would cause no impact.

SUGAR CANE IN BRAZIL
• 5 millions of hectares
• Sugar cane: 360 millions tons/year
• Ethanol: 14 million m3/year
• Cars run with 75% gas and 25% ethanol
• Flex fuel
17
SUGAR CANE IN BRAZIL
• Power produced by sugar cane biomass: 2,100 MW (2/3 self consumption)
• Share of electricity surplus can be increased through the use of better technology
• Total reduction of CO2: 46 million tons/year
