The city of Porto Alegre (RS) concluded in the first week of the year the migration of all medium voltage public buildings to sustainable energy in the Free Energy Market.
The initiative covers 60 facilities, such as the Emergency Hospital, Presidente Vargas Maternal and Child Hospital, the Asphalt Plants, the Municipal Palace and the Municipal Administrative Center.
According to the city government, the project – which began in April 2024 and was completed in January 2025 – prevented more than 300 tons of CO2 from being emitted into the environment.
Furthermore, Ana Pellini, municipal finance secretary, states that “more than R$1,2 million in savings have already been recorded in the first year and the expectation is to save around R$3 million annually from this year onwards with the conclusion”.
Next Steps
The forecast is that 4,1 MW of total power will be installed, enough to meet the energy demand of 441 low-voltage installations, in places such as basic health units, the Public Market, the Intendente José Montaury Building, among others.
After holding a public consultation and hearing to improve studies between November and December 2023, the notice was analyzed by the TCE (State Court of Auditors).
Giuseppe Riesgo, municipal secretary of Partnerships, highlights that “with this contract, in the form of an administrative concession, the private partner will be responsible for the implementation, management, maintenance and operation of the photovoltaic plants for a period of 26 years, operating under the credit compensation system to reduce the energy consumption of municipal buildings”.
