[1] Refer to concessions, by means of authorization, of wind power generation in the independent production modality, commercialized in the scope of Alternative power source program (‘Proinfa’). The assets linked to the exploration right are registered in intangible assets.
[2] These refer to power transmission concession agreements which, in accordance with IFRS 15, are classified as contract assets as they are subject to the satisfaction of performance obligations in the provision of the electric energy transmission service.
[3] On July 17, 2020, CEMIG GT filed a statement of its interest in extending these plants concession, to ensure its right of option under the legislative changes currently under discussion, relating to the group of measures to modernize the energy sector. Any actual decision will only be made after publication by the Brazilian Mining and Energy Ministry and by the grantor, ANEEL (‘Agência Nacional de Energia Elétrica’), of the conditions for extension, which will be submitted to decision by CEMIG’s governance bodies at the due time.
[4] On October 7, 2022, the addenda to the concession contracts of these plants were signed to include the new effective date of the grant.
[5] Refer to power generation concession agreements that are not in the scope of IFRIC 12, whose infrastructure assets are recorded as property, plant and equipment since the grantor does not control to whom the services should be provided and their price, and their energy is mainly sold in the Free Contracting Environment (‘ACL’).
[6] In February 2023, CEMIG GT, aiming to guarantee its right to request a new grant of the concession, filed its expression of interest in the extension of the concession of UHE Sá Carvalho through transfer of shareholding control to its wholly owned subsidiary Sá Carvalho. CEMIG GT reiterates that this expression of interest has the sole purpose of ensuring its right to an eventual extension of Concession Contract 01/2004, for up to 30 (thirty) years, at the discretion of the granting authority, after the required completion of the process of transfer of shareholder control, in accordance with the current legislation, which still has premises pending definition by the Ministry of Mines and Energy - MME.
[7] ANEEL changed, through Authoritative Resolution 12,137, of June 14, 2022, the end of the validity of the authorization grants of these plants, due to the repactuation of the hydrological risk (‘GSF’).
[8] Plant eligible for the extension of the concession due to the agreement with ANEEL and that, since it has been granted through an authorizing resolution, awaits the reformulation of this act to include the new date.
[9] On September 29, 2022, and October 1, 2022, ANEEL authorized the start of commercial operation of the Generating Units ‘UG-01’ and ‘UG-02’, respectively, both from PCH Poço Fundo. The start of commercial operation of the UG's occurred approximately 3 months before the supply deadline established in the A-4 Auction held by ANEEL in June 2018, when the incremental energy resulting from the expansion of PCH Poço Fundo (9.16 MW to 30.00 MW and the physical guarantee from 5.79 average MW to 16.59 average MW) was sold (information of MW not audited).
[10] Refers to energy generation concession contracts whose concession bonus revenue is classified as financial assets of the concession.
