Cemig SIM Expands Its Distributed Generation Portfolio by Taking Full Control of Solar Plants, Strengthening the Supply of Clean Solar Energy and Growth Strategy in Brazil
On December 22, 2025, Cemig SIM, a wholly-owned subsidiary of Companhia Energética de Minas Gerais (Cemig), announced the completion of the acquisition of a stake in three solar plants for distributed generation, totaling 10 MWp of installed capacity. According to an article published by the Cenário Energia website, the operation, valued at R$ 52.8 million, reinforces the group’s strategy of expanding its presence in the solar energy market and consolidating assets aimed at directly serving consumers.
The transaction involves the purchase of a 51% stake in two solar plants and 100% of a third unit, resulting in full control of the enterprises by Cemig SIM. As a result, the company ceases existing partnerships and now holds full ownership of all its distributed generation assets, strengthening its governance and operational efficiency.
Acquisition Reinforces Cemig SIM’s Strategy in Distributed Generation
The incorporation of the new assets represents a significant advance in consolidating Cemig SIM’s portfolio in the distributed generation segment, considered one of the most dynamic in the Brazilian electricity sector. The added 10 MWp increase the company’s capacity to serve, especially in Minas Gerais, a state that leads the national ranking of installed capacity in solar distributed generation.

Copel boosts solar energy in Paraná and brings innovation to public schools, promoting savings on electricity bills, energy efficiency, and a direct impact on the quality of education.
Furthermore, the operation eliminates shared governance structures. By taking 100% control of the assets, Cemig SIM can fully capture the economic results of the solar plants, while reducing risks associated with joint decision-making.
This model can favor economies of scale, standardization of processes, and greater operational efficiency, essential factors in an increasingly competitive market.
Solar Plants Drive the Expansion of Solar Energy in Brazil
The photovoltaic solar plants for distributed generation play a central role in the expansion of solar energy in the country. This model allows consumers access to renewable electricity without the need to invest directly in panels or their own infrastructure.
Through the electricity compensation system, consumers benefit from predictable costs and reduced exposure to tariff fluctuations, making distributed generation an attractive alternative for businesses and households.
Cemig SIM has positioned itself as one of the leading platforms in this segment, offering integrated solutions that combine generation, management, and provision of clean energy.
Solar Energy and Operational Efficiency with Full Control of Assets
The decision to take full control of the acquired solar plants strengthens Cemig SIM’s management capabilities. The centralization of administration allows for greater operational agility, from maintenance to evaluating expansion opportunities for the enterprises.
From a financial perspective, the complete capture of the revenues generated by the assets contributes to the dilution of administrative and operational costs, increasing the profitability of solar energy projects.
This move also enhances the strategic flexibility of the company, which now integrates the solar plants with other solutions offered to the market, such as energy efficiency and innovative supply models.
Cemig’s Strategic Planning Guides Investments in Clean Energy
The operation announced by Cemig SIM is directly linked to Cemig’s Strategic Planning, which has been reinforcing its actions in renewable sources and consumer-oriented businesses.
The Companhia Energética de Minas Gerais is one of the largest integrated companies in the Brazilian electricity sector, with operations in generation, transmission, distribution, and commercialization of energy. In recent years, the company has increased investments in solar energy, following the structural transformations of the electricity sector.
The consolidation of distributed generation as a strategic pillar allows the group to explore operational synergies, diversify revenues, and respond more agilely to regulatory and technological changes.
Legal Framework for Distributed Generation Favors Sector Consolidation
The progress of Cemig SIM occurs at a time of greater regulatory maturity for distributed generation in Brazil. With the regulation brought by Law No. 14,300/2022, the sector began to operate under a new legal framework, which provided more predictability but also required greater efficiency from the agents.
In this context, the acquisition of solar plants already in operation or in advanced development phases has proven to be a recurring strategy, allowing for a reduction of regulatory and implementation risks.
The incorporation of the 10 MWp reinforces the competitiveness of Cemig SIM, while expanding its asset base in a more stable regulatory environment.
Minas Gerais Strengthens Cemig SIM’s Role in Distributed Generation
Minas Gerais occupies a prominent position in the national solar energy market, leading in installed capacity for distributed generation. This context favors the strategy of Cemig SIM, which has a strong regional presence and deep knowledge of the local electricity network.
The acquired solar plants increase the capacity to serve residential, commercial, and industrial consumers, offering flexible solutions aligned with market demands. Additionally, the geographical proximity facilitates operational management and strengthens the company’s relationship with clients and strategic partners.
Corporate Governance and Long-Term Value Creation
From a corporate perspective, the consolidation of assets strengthens Cemig SIM’s governance. The elimination of corporate partnerships simplifies decision-making processes and increases transparency in the management of the enterprises.
Financially, the complete capture of the cash flows generated by the solar plants contributes to long-term value creation, in line with the interests of Cemig’s shareholders.
This move also enhances the company’s ability to reinvest in new solar energy projects and expand its role in sustainable energy solutions.
Prospects for Cemig SIM in the Solar Energy Market
The conclusion of the acquisition indicates that Cemig SIM is likely to maintain an active stance in evaluating new opportunities in the distributed generation market. The trend is to combine organic growth with strategic acquisitions, seeking scale and efficiency.
In a context of energy transition, increasing electrification of the economy, and greater demand for sustainable solutions, robust distributed generation platforms gain strategic relevance.
By reinforcing its portfolio of solar plants and aligning its operations with Cemig’s group planning, Cemig SIM positions itself to expand its share in the Brazilian solar energy market, contributing to a cleaner, more efficient, and decentralized electrical system.
