HYDRO-THERMAL TRANSITIONHYDRO-THERMAL TRANSITION

• the expansion of a large interconnected power system, with significant predominance of hydro renewable primary source requires an increasing thermal contribution due to:

• gradual exhaustion of the economic and environmentally viable hydro potential

• loss of self-regulation capacity due to lower water storage capacity in the reservoirs related to the system load growth.

• Canadian electric system over

the past 50 years holds many

similarities with the situation of

the Brazilian over last 15 years.

• From a contribution of over 90%

in 1960, hydroelectricity share

in Canada declined steadily until

1990, stabilizing around 60%.

EXPANSION POST-2030EXPANSION POST-2030

• Mix: natural gas (depending on the amount and cost of pre-salt), coal (depending on the

viability of CCS and clean coal) and nuclear (public acceptance)

• Renewables (biomass, wind, solar) and expansion of energy efficiency programs

(increasing marginal expansion costs) will be an essential supplement

UNIQUE COMPETITIVE ADVANTAGES OF NEW RENEWABLES IN BRAZIL:

•Wind – Solar match

•Wind – Hydro match

• Energy storage in reservoirs

• Saving water and

• Enhancing hydroelectric load following and self-regulation (long term) capabilities
