Companhia Paranaense de Energia – Copel, a company that generates, transmits, distributes and sells power, with shares listed on the NYSE (ELPVY, ELP), the B3 (CPLE3, CPLE5, CPLE6) and the LATIBEX (XCOP), pursuant to CVM Instruction 480, of December 7, 2009, hereby informs its shareholders and the market in general of the following related-party transaction, entered into on November 24, 2017:

Name of Related Parties	Usina Elétrica a Gás de Araucária Ltda. – UEG Araucária e Petróleo Brasileiro S.A – Petrobras.
Relationship with the Company	UEG Araucária is a private-law legal entity, incorporated as a limited-liability company, owned by Copel, which holds 20% of the capital stock; Copel Geração e Transmissão, which holds 60% of the capital stock; and Petrobras, which holds 20% of the capital stock.

  Detailed justification of why the issuer’s management considers that the transaction is conducted on an arm’s length basis or envisages appropriate compensatory payment:   Araucária TPP (a plant owned and operated by UEG Araucária) does not have Energy Commercialization Agreements related to the sale of generated energy, operating as a Merchant. This means that it is called upon to generate energy by the National System Operator (ONS) when the Marginal Cost of Operation (CMO) exceeds the Unit Variable Cost (CVU) of the plant. Araucária TPP’s operation is, therefore, determined by the merit order of its costs or request by the ONS. In light of this, the Company’s management considers that the transaction was conducted on an arm’s length basis and envisages appropriate compensatory payment. The Company thus believes that the agreement resulted in the reduction of Araucária TPP’s variable costs, placing it at a level below the Marginal Cost of Operation of the electrical sector, enabling its possible operation. In addition, the exclusion of the take or pay clause does not impose risk on UEG Araucária if the National Interconnected System (SIN) conditions are not appropriate for the dispatch of Araucária TPP.
