The solar array will comprise roughly 225,504 bifacial photovoltaic modules rated at 620 Wp each, mounted on 4,176 single-axis trackers configured in a north-south orientation with east-west horizontal tracking. The battery energy storage system consists of 176 units housed in 20-foot shipping containers mounted on concrete supports, with environmental documentation attributing 5 MW capacity to each container. The filing does not specify total energy capacity in MWh or discharge duration.
Electricity will flow from modules through combiner boxes to transformation centers, where conversion from direct to alternating current occurs alongside voltage elevation from low to medium tension. These centers will connect to a step-up substation. Grid injection into Chile’s Sistema Eléctrico Nacional will utilize a sectioning substation designed to interface with the existing 2×220 kV Nueva Ventanas–Nogales transmission line, leveraging current infrastructure rather than requiring new transmission construction.
Construction is scheduled to begin in October 2028 pending receipt of environmental approval, with an 18-month timeline extending through April 2030. The build phase will require an average workforce of 186, peaking at 450 workers. Commercial operations are slated to commence in April 2030.
Permanent infrastructure beyond the solar field and battery system includes transformation centers, step-up and sectioning substations, operations and maintenance facilities, and sectioning towers. The developer has committed to voluntary environmental measures including preferential hiring from Puchuncaví and Quintero municipalities, particulate matter control, erosion monitoring, fauna protection measures, archaeological monitoring, ecological refuge maintenance, and soil improvement initiatives.
