a)Energia Solidária Program, created by state law No. 20.943/2021, replacing the Luz Fraterna Program, establishes the payment of electricity consumption to benefit low-income families, residing in the State of Paraná, whose properties - consumer units - are used exclusively for residential purposes, whether in urban or rural areas, and fulfill the requirements established in articles 2 and 3 of this law.

In March 2018, the amount of R$159,274 was settled. The principal interest, fine and monetary restatement totaled R$158,849. For the collection of these charges on electricity bills for the period of September 2010 to June 2015, monitory action No. 0006254-29.2018.8.16.0004 was filed in November 2018 against the State of Paraná, which is responsible for paying the invoices under the terms of State Law No. 14.087/2003. We highlight that despite the negotiations maintained by Management, seeking to settle the debt, uncertainties still exist regarding the realization of this asset and, therefore, this asset was not recognized, in compliance with the current accounting standards. For the tax treatment, as determined by the Brazilian Federal Revenue Office in the Normative Instruction No. 1,753/2017, the Company has taxed this revenue. The lawsuit between Copel and the State of Paraná is currently before the Paraná Court of Justice, where the parties are seeking a review of the decision that recognized part of the claim. The appeal was heard in October 2023 and the judgment has not yet been published. In April 2023, Copel filed a second lawsuit under No. 0000873-24.2023.8.16.0179 to recover the balance of R$25,936. The Management reinforces that it is making all necessary efforts and taking all appropriate measures to preserve the Company's interests.

b)Reimbursement of wages and social charges for employees transferred to the Paraná State Government. Balances presented are net of expected credit loss.

c)BNDES is the controller of BNDES Participações S.A. - BNDESPAR, which holds shares in Copel (Note 27.1). BNDES and BNDESPAR acquired all the debentures issued by the subsidiaries Nova Asa Branca I, Nova Asa Branca II, Nova Asa Branca III, Nova Eurus IV and Ventos de Santo Uriel.

k)Energy sales contract signed between Copel COM and the Instituto de Tecnologia do Paraná - Tecpar (a public company of the State Government that supports innovation and economic and social development in Paraná and Brazil), Information Technology Company of Paraná - Celepar (mixed capital company that is part of the indirect administration of the Paraná State Government), Portos do Paraná (port complex that operates as a public company of the State Government, subordinated to the Infrastructure and Logistics Secretary of State) and Assembleia Legislativa do Paraná (legislative assembly of the State).

Copel's direct and indirect subsidiaries have short and long-term energy purchase and sale agreements entered with each other, carried out in accordance with the criteria and definitions of the regulated environment. Both the balances of existing transactions and the balances of commitments are eliminated from each other when preparing the Company's consolidated financial statements.

In addition, as of December 31, 2024, Copel GeT has energy purchase commitments with Dona Francisca amounting to R$15,964 (R$31,971 as of December 31, 2023) and Copel COM has energy sales commitments signed with agencies and / or entities connected to the Paraná State Government, including Sanepar, amounting to R$201,272 (R$216,029 as of December 31, 2023).
