Stellantis México has submitted an environmental impact assessment to Mexico’s Ministry of Environment and Natural Resources (Semarnat) for two solar plants with a combined capacity of 21.56 MWp at its industrial complex in Saltillo, Coahuila. The project is named PS 360E Stellantis Saltillo Complex.
The installations will supply electricity to the automaker’s industrial facilities. Stellantis, which manufactures vehicles under brands including Ram, Jeep, Fiat, Peugeot, and Citroën, operates Ram truck assembly and engine manufacturing facilities at its industrial complex in the Derramadero area.
According to the submitted documentation, the project will occupy 61.21 hectares within the industrial property, approximately 15 kilometers southwest of Saltillo.
The two plants, PS 360E Stellantis Saltillo Complex I and II, will each have a capacity of 10.78 MWp, with 9 MWac and a net capacity of 8.8 MW. The first will supply the load center at the Saltillo truck plant, while the second will serve the load center associated with the Saltillo Sur engine plant and the Chrysler Camión facilities.
The project will use approximately 33,696 monocrystalline bifacial solar modules rated at 640 W each, mounted on 216 single-axis solar tracking structures. The trackers will be oriented north to south, with a tilt range of up to 60 degrees in either direction.
Annual electricity generation is estimated at 51.68 GWh, comprising 25.60 GWh from the first plant and 26.08 GWh from the second.
Both plants will operate as grid-connected self-consumption facilities without exporting surplus electricity to Mexico’s National Electric System. All generated electricity will be consumed within the automotive complex, with each plant connected independently to its respective load center.
The electrical infrastructure will include four transformer centers and four independent medium-voltage circuits operating at 13.8 kV. The circuits will connect the solar installations to an existing substation through underground sections and approximately 1.1 kilometers of overhead lines.
The proposed schedule includes site preparation and construction, with commissioning planned for month 24 after the project begins. The installations are expected to have a 30-year operating life. Public documentation does not disclose the investment amount.
The project builds on the relationship between Stellantis and Argentine energy company 360Energy, in which the automaker acquired a 49.5% stake in 2024.
The companies are already developing renewable electricity projects for Stellantis industrial facilities. In April 2026, they commissioned an 8 MWp solar plant at the Córdoba Industrial Hub in Argentina, expected to generate 16.7 GWh annually for Stellantis’ automotive factory.
