All the plants of the own generation park and all the plants in partnership participate in the Electric Power Reallocation Mechanism – MRE or ERM, a system to share hydrological risks, in which the participating plants transfer the generated energy in surplus to their physical guarantee to the plants that generated levels lower than the physical guarantee limits.

In addition to the aforementioned projects, Celesc Geração has a shareholding in an electrical energy transmission project, containing five sections of 230kV and 525kV transmission lines and a 525/230kV substation, as shown in the following table:

Expansion Projects

The Company has a portfolio of expansion/reactivation projects for its own plants. As for physical guarantee (new or incremental), the aim is to obtain an average of 50% of the plant’s total capacity factor after expansion/reactivation, a pattern observed for other projects in operation with similar characteristics.

In new businesses, seeking to diversify its operations into renewable sources, a guideline of its Master Plan, Celesc, in 2022, began operating in solar photovoltaic distributed generation. The Company’s strategic direction points to the opening of new business models that can increase non-distribution revenues and among them is the Distributed Generation (GD) segment, taking into account the growth prospects of this segment.

The Distributed Generation Business Plan foresees the implementation of photovoltaic solar projects in the concession area of ​​the Celesc Group distributor. All projects are included within the regulatory window provided for by Law No. 14,300/22, which maintains the current rules of the energy compensation system until December 31, 2045. This factor makes it possible to achieve greater profitability in the solar farm model practiced by Celesc Geração. It is also worth highlighting that the additional 3.6 MW, approved in the last review of the GD Business Plan, will be prospected during 2023. This portfolio expansion will also be linked, above all, to the projects’ inclusion in the regulatory window of Law no. 14,300/22, mentioned above.

Energy Trading

In addition to electrical energy generation and transmission projects, Celesc Geração, since its incorporation, has been selling electrical energy produced by its own generating complex 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, in order to provide new business and revenue, maximizing the benefits of its territorial presence, the Company approved the Energy Trading Business Plan, which expands Celesc G’s operations in this segment.

Thus, the Company has been positioning itself in the energy trading segment and related businesses, demonstrating greater involvement in the market, especially in Santa Catarina.
