April 26 (Renewables Now) - Sonnedix Power Holdings Ltd has initiated the environmental permitting process for a project to build a 175-MWp solar farm with energy storage in the Chilean region of O’Higgins.

The global independent solar power producer would invest USD 140 million (EUR 115.6m) to build the whole set-up, including a substation and a high-voltage transmission line, its application for the environmental review shows.

The project, named Pelequen, will incorporate a 50-MW/200-MWh system of energy storage in lithium-ion batteries. The batteries would be housed in 40 containers, each with a storage capacity of 5.2 MWh.

The solar farm component, which would generate 175 MW of DC power, is envisaged to feature close to 292,000 bifacial modules of 600 MWp.

Sonnedix estimates construction would begin in April 2023. Depending on the outcome of the permitting process, the Pelequen project is set to be finalised in October 2024, according to the filed timetable.
