Cemig SIM Announces Special Discounts with Solar Energy by Subscription, Offering More Savings on Electricity Bills for Consumers in Minas Gerais During the Black November Campaign
Cemig SIM has announced a new promotional campaign called Black November, offering double savings on electricity bills during the first three months of subscription for customers in Minas Gerais. The information was released by Agência Minas on Tuesday (18), highlighting that the action is aimed at residential, commercial, and rural consumers. The initiative reinforces the company’s expansion in the solar energy market and its effort to popularize the subscription model, which does not require panel installation or initial investment.
Cemig SIM and the Solar Energy Subscription Model
The promotion is valid until November 30, and subscription can be done entirely online. The proposal aims to democratize access to renewable energy and reduce monthly expenses during a period of high electricity costs in Brazil. Cemig SIM, a subsidiary of the Companhia Energética de Minas Gerais, operates in the remote distributed generation segment.
Unlike conventional solar energy systems installed on rooftops, this model operates from solar plants managed by the company. Customers receive credits on their energy bills according to the generation from the plants, without the need for major renovations in their property.

This format has been growing in Brazil due to ease of access and the absence of installation costs. It is especially advantageous for consumers living in apartments, rented properties, or homes without adequate space for solar panels.
The company states that its goal is to increase the population’s participation in sustainable and low-cost solutions. Cemig SIM already operates dozens of solar plants in Minas Gerais and leads the state market for remote distributed generation. The model also contributes to the state’s environmental goals, reducing emissions and encouraging ESG practices.
Black November Cemig SIM: Main Campaign Details
The Black November campaign, according to Agência Minas, offers an unprecedented condition for new customers: double savings in the first three months, followed by discounts of up to 16% in the following months. To participate, the consumer must meet certain requirements defined by the company.
The main points are:
- Promotion valid until November 30, 2025.
- Double savings on the contracted amount.
- Permanently discounted after the initial period, reaching up to 16% on electricity bills.
- Applicable to energy bills with a minimum amount of R$ 160.
- Completely digital subscription process.

This policy aims to encourage the entry of new consumers into the renewable energy market, especially at a time when electricity costs have become a national concern due to tariffs, flags, and climatic fluctuations affecting the power sector.
Saving on Electricity Bills and Impact for Consumers in Minas Gerais
The promise of savings on electricity bills is the main attraction of the campaign. In a scenario of rising household expenses, initiatives like this can alleviate part of the family budget. The savings occur through the application of energy credits generated at Cemig SIM’s plants, which reduce the final bill amount.
Furthermore, the subscription model avoids the high costs typical of owning photovoltaic systems. In residential installations, for example, the initial cost can exceed R$ 15,000, depending on the necessary power. In Cemig SIM’s model, there is no such outlay, allowing consumers with lower purchasing power to access solar energy.
Another positive impact is related to the environment. By opting for solar energy, the customer reduces their indirect carbon emissions, contributing to state and national sustainability goals.
Solar Energy in Minas Gerais: Growth and Environmental Relevance
The state of Minas Gerais is one of the leaders in distributed generation in Brazil, according to the National Electric Energy Agency (ANEEL). Part of this advancement is due to the favorable climate, high levels of solar radiation, and incentive policies created in recent years.
The expansion of solar energy has provided economic and environmental benefits, such as:
- Job creation in the photovoltaic sector
- Reduction of environmental impacts related to the electricity matrix
- Increased energy autonomy in remote areas
- Incentive to innovation in sustainable business models
In this context, campaigns like Black November help to further accelerate the adoption of renewable sources.
Limitations and Important Conditions of the Campaign
Although the campaign is advantageous, some conditions require consumer attention. Among them:
- The promotion requires a minimum consumption of R$ 160 on the bill.
- Savings may vary according to the generation from the solar plants.
- The permanent discount after the initial three months can reach up to 16%, but it is not fixed.
- Existing customers may have restrictions on migrating directly to the new conditions.
These points emphasize the importance of reviewing the contract and conditions before subscribing, ensuring that the benefit meets the user’s needs.
Expansion of Solar Energy by Subscription in Brazil
Cemig SIM has already announced plans to expand solar energy by subscription to other states in the Southeast and Center-West regions, according to public information released in 2025. The model has been gaining national strength by offering democratic access to clean energy.
The trend points to:
- Increased competitiveness in the sector
- Gradual cost reduction
- Expansion of distributed generation
- Incentive for sustainable public policies
This way, Brazilian consumers can benefit from more accessible prices and a greater variety of services related to renewable energy.

By offering double savings in the first three months and continuous discounts, Cemig SIM creates an entry point for consumers who wish to participate in the energy transition without initial investments.
