COPEL will be one of the companies less affected
by Brazil’s electric sector new rules

     Companhia Paranaense de Energia - COPEL, pursuant to CVM Rule 358/2002, informs the market that in view of the rules enacted by Provisional Measure (MP) nº 579 of September 11, 2012, is still analyzing its effects on the Company’s businesses. Initially, we do not see relevant impacts on our activities. As far as generation segment is concerned, COPEL only has 5% of its installed capacity or 270 MW to mature until 2017. Next generation concessions will mature in 2023, 2029 and 2030.

Referring to the distribution segment, the Company went through the 3^rd Cycle of Tariff Review last June, resulting in an average tariff effect felt by customer of -0.65%. In relation to MP 579, the tariff reduction impacts will be mitigated by decreased sector charges, lower energy purchase cost and reduced basic grid charges. Therefore, COPEL Distribuição's EBITDA level should not be affected.

Finally, concerning transmission segment, currently COPEL has 2,023 km of transmission lines and 10,902 MVA of capacity at substations, the revenue of which in 2011 accounted for less than 3.5% of the group’s consolidated net revenues.

Curitiba, September 12, 2012.

Sincerely,

Ricardo Portugal Alves
CFO and Investor Relations
