Hospitals in Minas Gerais Receive Sustainable Projects from Cemig, with Solar Energy Systems and LED Lighting that Reduce Costs and Enhance Service Efficiency
Cemig made an important investment in the first half of 2025, allocating R$ 13.6 million for the modernization of approximately 590 hospitals and municipal health units in Minas Gerais. The initiative, part of the Energy Efficiency Program (PEE), regulated by the National Electric Energy Agency (Aneel), covered 75 cities and focused on installing solar power plants, replacing obsolete equipment, and adopting LED lighting.
This action brings positive direct impacts for public health and sustainability, reducing operational costs and allowing the saved resources to be applied to other hospital needs.
Scope of Cemig’s Modernization in Minas Gerais
The project included hospitals and primary health care units in all regions of the state. Highlights include:
-
The Sol do Agreste Photovoltaic Complex begins operations in Pernambuco and accelerates the expansion of solar energy in Brazil, directly impacting the reduction of emissions and strengthening the sustainable energy matrix.

-
Roraima bets on the sun to escape high tariffs: Amid the energy crisis and price hikes, solar energy is growing in Roraima and transforming consumption in the North region.
-
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.
- 590 health institutions benefited across 75 municipalities in Minas Gerais;
- R$ 1.9 million invested just in the Central region, including Belo Horizonte;
- In Curvelo, Santo Antônio and Imaculada Conceição hospitals received new autoclaves, with funding close to R$ 1 million.
According to Cemig, the program was structured to serve both large hospitals and small municipal units, focusing on reducing electricity expenses and improving infrastructure.
Benefits of Hospital Modernization
One of the central points was the replacement of old autoclaves with more efficient models. These devices, essential for the sterilization of medical instruments, now consume less energy and optimize internal processes.
According to Filipe Randazzo, Energy Efficiency Analyst at Cemig, a large part of hospital activities directly depends on energy, making energy consumption a crucial factor for the operation of health units.
With the modernization promoted by Cemig, it is possible to reduce costs with energy and maintenance of equipment, allowing hospitals to direct saved resources to other priority needs.
This reduction in expenses has a direct effect on the quality of services provided, freeing up budgets for medications, renovations, and hiring staff.
Solar Energy in Hospitals in Minas Gerais
Another highlight was the installation of photovoltaic plants in nine hospitals in the first half of 2025. The cities benefiting were: Mutum, Jordânia, Itambacuri, Buritizeiro, Campo do Meio, Cachoeira de Pajeú, Congonhas, Vespasiano, and Itamonte.
With the adoption of solar energy, hospitals began to generate part of the electricity consumed, becoming less dependent on the conventional grid. This ensures long-term savings and reinforces the public sector’s commitment to clean and renewable sources.
In addition to reducing energy expenses, the measure also strengthens energy security, an essential factor for hospitals that cannot afford failures in supply. The use of renewable energy also helps reduce greenhouse gas emissions, aligning public health with sustainable practices.
LED Lighting as an Efficient Solution
The replacement of traditional light bulbs with LED lighting was another impactful measure. This technology is up to 80% more efficient than incandescent bulbs and lasts about 25 times longer, reducing maintenance and replacement costs.
In hospitals, adequate lighting is vital for the safety of patients and professionals, as treatment, surgery, and emergency room environments require clear and consistent light. With the replacement, spaces become more functional and comfortable, without overloading electrical systems.
Cemig highlights that, in addition to cost savings, LED reduces heat buildup in environments, contributing to greater thermal comfort, which is relevant in institutions with high foot traffic.
Expansion of Healthcare Investment by 2027
The current project is part of “Cemig in Hospitals,” within the Energy Efficiency Program. Between 2025 and 2027, there is a forecast to invest R$ 75 million to benefit about 4,000 health institutions in Minas Gerais.
The goals include:
- Replacement of 290,000 bulbs with LEDs;
- Installation of 60 solar plants;
- Replacement of 110 autoclaves with modern models.
This expansion will enhance positive impacts on energy efficiency and sustainability in the healthcare sector, ensuring that more municipalities have access to modern equipment and clean energy sources.
History of Cemig’s Investments in Energy Efficiency
In the last 25 years, Cemig has already invested over R$ 1.1 billion in energy efficiency projects in Minas Gerais. The results achieved include:
- 7,500 GWh saved, equivalent to the annual consumption of 4.8 million families;
- 525,000 tons of CO₂ avoided in the atmosphere.
This history reinforces the importance of ongoing programs that unite sustainability, social responsibility, and technological innovation. The company is nationally recognized for its efforts in renewable generation and solutions that contribute to the energy transition.
Impact on Public Health and Sustainability
The modernization carried out by Cemig demonstrates how public policies and corporate initiatives can transform resource management in healthcare. The savings obtained from reduced energy consumption and maintenance of equipment open avenues for new investments in infrastructure and service quality.
Moreover, the inclusion of solar energy and LED lighting strengthens the sustainability agenda, aligning Minas Gerais with national and international commitments to reduce greenhouse gas emissions.
These advancements also help municipalities meet energy efficiency targets set by the federal government and encourage innovation practices in strategic sectors.
Relevance of Cemig’s Investment
The investment of R$ 13.6 million from Cemig in the modernization of 590 hospitals and health units in Minas Gerais is a concrete example of how energy efficiency can bring direct benefits to the population.
With the installation of solar power plants, replacement of autoclaves, and adoption of LED lighting, hospitals in Minas Gerais reduce costs, increase operational efficiency, and reinforce their commitment to sustainability.
The continuation of the program until 2027, with a forecast of R$ 75 million in contributions, shows that initiatives like this can become national references, uniting innovation, public health, and environmental preservation. At the same time, it positions Minas Gerais as an example in adopting practices that balance development and social responsibility.
