OWNERSHIP AND CORPORATE STRUCTURE

Celesc Distribuição S.A.

Celesc Distribuição S.A. is a wholly-owned subsidiary of Centrais Elétricas de Santa Catarina S.A. – Celesc and operates in the electricity distribution segment, fully or partially serving 285 municipalities and 3,373,894 consumer units. Of the total amount of municipalities, 264 are covered by the distributor’s concession agreement (263 in Santa Catarina and 1 in Paraná) and 21 municipalities are covered as registered warrants, in concession areas of other distributors (17 in Santa Catarina and 4 in Paraná). The public distribution of electricity under the registered warrants regime is in accordance with ANEEL’s regulations, by reason of technical and economic convenience, as the concessionaire holding the concession does not have a network. Additionally, Celesc Distribuição is responsible for supplying power to 4 concessionaires and 20 distribution permissionaires, which operate in Santa Catarina municipalities not served by Celesc Distribuição.

The company distributed 7,806 GWh in the first quarter of 2024, reaching gross revenue of R$ 4,071.4 billion. The map shows the coverage of CELESC’s operating area.

Celesc Geração S.A.

Celesc Geração is the wholly owned subsidiary of the Celesc Group and operates in the electricity generation and transmission segments through the operation, maintenance and expansion of its own generation park, in addition to selling electricity and holding interest in power generation and transmission projects in partnerships with private investors.

The Company has its own generating complex consisting of 13 hydroelectric plants, in which 12 are in operation and 1 in the process of being reactivated. It also has two photovoltaic solar power plants in the Remote Distributed Generation model.

The Company holds a minority interest in another six hydroelectric generation projects, developed in a partnership with private investors, under the Special Purpose Entity (SPE) format, all of them already in operation. In the transmission segment, the Company holds a minority interest in an SPE in partnership with EDP – Energias do Brasil.

All generation and transmission projects are located in the state of Santa Catarina.

Celesc G’s total generation capacity in operation on March 31, 2024, was 131.01 MW, of which 119.77 MW was from its own park and 11.24 MW from the generation park set up with partners – already proportional to Celesc G’s shareholding interest in these projects. The hydroelectric generating plant being reactivated will have 1 MW of installed capacity.

All the plants of the Company’s own generation and the plants in partnership with other shareholders, in the hydroelectric model, participate in the Electric Power Reallocation Mechanism – ERM, or MRE in Portuguese, a risk-sharing hydrological system in which participating plants transfer their energy generated energy surplus to their physical guarantee to the plants that generated levels lower than their physical guarantee limits.

In addition to the aforementioned projects, Celesc Geração holds shares in an electricity transmission project, containing five stretches of 230kV and 525kV transmission lines and a 525/230kV substation, as shown in the table below:

Expansion Projects

The Company has a portfolio with projects to expand/reactivate its plants. As for the physical guarantee (new or additional), the Company seeks to obtain, on average, a 50% factor for the plants’ total capacity after their expansion/reactivation, which is a standard observed in other similar operational projects.

Seeking to diversify its activities in renewable sources businesses, as one of the guidelines of its Master Plan, in 2022, Celesc started to operate in photovoltaic solar distributed generation. The Company’s strategic direction points to the opening of new business models that can increase extra-distribution revenues, including the Distributed Generation (DG) segment, given its growth prospects.

The Distributed Generation Business Plan provides for the implementation of photovoltaic solar projects in the concession area of the Celesc Group distributor. All projects are included in the regulatory window provided by Law 14,300/22, which maintains the current rules of the energy compensation system until December 31, 2045. This factor enables the solar park model practiced by Celesc Geração to achieve higher profitability.

Energy Trading

In addition to electrical energy generation and transmission projects, Celesc Geração, since its incorporation, has been selling electric energy produced by its own generating park and by some of its subsidiaries. More recently, in compliance with the strategic guidelines of the Master Plan, seeking to diversify the Group’s business aimed at offering new business and revenue and maximizing the benefits of its territorial presence, the Company approved the Energy Trading Business Plan, which expands Celesc G’s operations in this segment.

We highlight that, on January 24, 2024, Celesc Geração obtained the approval to act as a Retail Trader with the Electric Energy Trading Chamber (CCEE), as resolved at its Board of Directors’ meeting number 1,379/2024. Therefore, the Company will be able to serve all Group A customers (high and medium voltage supply) who are eligible for migration to the Free Contracting Environment (ACL) in the retail modality, based on Ordinance 50/2022 issued by the Ministry of Mines and Energy (MME).

The structuring of Celesc Geração as an Energy Retail Trading Agent follows the premises of the Company’s Master Plan and the trends of the electricity sector. The Company has been selling energy in the free wholesale market since 2006, however, the entrance into the free retail market represents an important opportunity for the Celesc Group as it reinforces its presence in the sector, diversifies its revenue sources and maximizes the benefits of its territorial presence.

Accordingly, the Company has been positioning itself in the energy trading segment and related businesses, demonstrating a greater presence in the market, particularly in the state of Santa Catarina.
