     The industrial segment, which represented 32.4% of Copel’s captive market, consumed 5,632 GWh, growing by 0.5% year to date. This result was due to the higher number of customers, which totaled 84,887 by the end of September.

     The residential segment consumed 4,867 GWh, a growth of 3.8%, led by the higher credit and income growth. At the end of September 2012, this segment represented 28.0% of Copel’s captive market consump-tion, with the company supplying power to 3,169,888 residential customers.

     The commercial segment consumed 3,749 GWh, a growth of 4.8%, due to increasing sales from re-tailers in the concession area. At the end of the period, this segment represented 21.5% of Copel’s captive market consumption, with the company supplying power to 326,225 captive commercial customers.

     The rural segment consumed 1,512 GWh, growing by 8.0%, mainly due to the higher agricultural ex-ports from the State of Paraná. This segment represented 8.7% of Copel’s captive market consumption at the end of September, with the company supplying power to 374,759 rural customers.

     Other segments (public agencies, public lighting, public services and own consumption) consumed 1,636 GWh, up 3.2% in the period. These segments represented 9.4% of Copel’s captive market consumption, totaling 53,507 customers at the end of the period.
