Tractebel’s Hydro Allocation Process

Background

At CCEE the “resources” of a generation co. are compared to its sales on a monthly basis.


“Resources” stand for:

Purchases from third parties

Thermal generation

Hydro energy allocated
Difference between “resources” and sales is settled at Spot Price (PLD).

Tractebel 's energy availability is almost fully contracted up to 2010.

Tractebel is entitled to fuel reimbursement by CDE when coal-fired plants are dispatched
due to merit order or inflexibility.

200,000 tons of coal per month)

Hydroelectric generation above or below
the “Seasonalized” Assured Energy
is valued by “MRE Tariff” (~ R$ 8/MWh)

Allocated Energy (MRE)
Allocated Energy above or
below the “Seasonalized” Assured Energy
is settled by PLD

The impact on the results is less significant than the thermal substitution

An appropriate monthly allocation of the hydro resources over the year can mitigate the
exposure arising from the thermal substitution energy to be purchase at spot price

PLD in a year’s 1st half is likely to be lower than in 2nd half

Decision Traps

10
Regulatory uncertainties
•
Risk aversion mechanisms (i.e., Risk Aversion Curve and Target Level)
•
Changes in PLD pricing model
•
Out-of-merit thermal dispatch

GSF resulting from overall hydro allocation

Unexpected unavailability of power plants

Price/availability of short-term energy purchased from third parties to (i) offset a
net buyer position and (ii) leverage future overallocation

Trade off: sales of short-term energy at PLD+Δ% X future overallocation leverage
