Operating Highlights
► CEMAR’s total billed energy volume reached 1,236 GWh in 1Q13, 10.6% higher than in 1Q12. The
total volume distributed by CELPA (captive and free markets) totaled 1,650 GWh in 1Q13, representing
growth of 3.9% YoY.
► In CEMAR, energy losses of the last 12 months ending 1Q13 represented 20.4% of the required
energy, with a reduction of 0.3 percentage points compared to 20.7% recorded in 1Q12. In CELPA, total
losses ended the year at 35.9% of the required energy.
► In 1Q13, CEMAR’s DEC and FEC indexes (accumulated over the last 12 months) were 21.5 hours, a
decrease of 9.3%, and 11.2 times, a decrease of 7.0%, compared to those observed at the end of 1Q12.
In CELPA, these same indexes closed the quarter with improvements of 7.0% and 9.0%, respectively.
Analyzing CELPA’s indexes only in the quarter, we can see improvements of 24.7% and 22.4%,
respectively.

7. 7
► Net operating revenues (NOR) in 1Q13 reached R$1,065.9 million, almost twice 1Q12’s NOR, which
reflects the beginning of the consolidation of CELPA.
► In 1Q13, EBITDA totaled R$59.8 million, a 52.2% decrease compared to the 1Q12 amount, due to the effect
of the dispatch of thermal plants. If we consider the constitution or amortization of net regulatory assets,
Equatorial’s Adjusted EBITDA would have been R$170.3 million, 80.8% higher than 1QT12’s.
► The net result of the quarter was a loss of R$24.6 million, due to the effect of the dispatch of thermal plants.
Considering the constitution or amortization of net regulatory assets, Equatorial’s adjusted net income would
have been R$37.4 million, 49.0% higher than 1Q12’s.
► In 1Q13, Equatorial's consolidated investments totaled R$169.0 million, 38.2% lower than those made in
1Q12. If we consider only CEMAR’s own investments, the growth amounted to 5.0% in the quarter.
► On April 19, 2013, CELPA’s EGM partially approved its capital increase, through which Equatorial now holds
96.18% of CELPA’s total capital.
► As of this quarter, we are no longer consolidating the interest of 25% in Geramar. On a pro-forma basis, we
also did not consolidate its numbers in previous quarters in this Earnings Release. Geramar’s results only
impact Equatorial’s Consolidated Income Statement in the Equity Income line.
