The municipality of Junín announced the construction of one of the most important solar parks in the province of Buenos Aires, with an investment close to 20 million dollars.
The project combines private investment, renewable energy generation, and local development, consolidating the district as a leader in the energy transition.
Magnitude of the project and environmental impact
The work is being developed on a plot of 50 hectares and includes the installation of more than 42,000 solar panels.
With an installed capacity of 20 megawatts (MW), the park will be able to supply energy to more than 10,000 homes, becoming one of the most significant photovoltaic ventures in the interior of Buenos Aires.
According to official estimates, the park will avoid the emission of 17,500 tons of carbon dioxide per year, significantly contributing to the reduction of greenhouse gases.
This contribution reinforces Junín’s commitment to environmental sustainability and the fight against climate change.
Local development and employment
The construction will generate between 80 and 120 direct jobs, in addition to boosting sectors related to services, logistics, maintenance, and regional suppliers. In this way, the project impacts not only the energy matrix but also the local economy.

Execution and technical support
The work will be carried out by Genneia, a leading renewable energy company in Argentina, with experience in wind and solar parks in different provinces.
Their participation guarantees technical and operational support for the development of the project.
Strategic importance in Buenos Aires
Solar energy has become a key tool for:
- Decentralizing the electrical grid and improving service in rural areas.
- Diversifying the energy matrix, reducing dependence on fossil fuels.
- Boosting distributed generation (DG), through the PROINGED program, which installs solar parks in interior localities.
- Promoting rural development, through the PERMER project, which brings electricity to communities far from the conventional grid.
- Reducing costs and emissions, consolidating solar energy as a profitable and sustainable alternative.
Situation and potential
The province of Buenos Aires combines solar energy with lithium batteries to meet demand outside solar hours. Studies from the Biblioteca Digital UNCUYO indicate that the central region is suitable for the expansion of this energy. Although it faces investment challenges, as warned by SolarPower Argentina, the sector presents a great growth projection.
The Junín solar park represents a milestone in the Buenos Aires energy transition. With environmental, economic, and social benefits, the initiative reinforces the district’s profile as a city prepared for the challenges of sustainability and the democratization of energy access.
