en.Wedoany.com Reported - Recently, the municipality of Camarones in Chile's Arica and Parinacota region approved the Environmental Qualification Resolution (RCA) for the "Transmission Line and Black BESS Energy Storage Power Plant" project, developed by Inversiones Black Solar, part of the Mack Energy Group. The project plans to construct a Black BESS energy storage system, along with supporting transmission lines and substation facilities.

The Black BESS energy storage system utilizes lithium-ion battery technology, with an installed capacity of 350 MW, an energy storage capacity of 1,409 MWh, a discharge duration of 4 hours, and a total investment of approximately $220 million. It is expected to commence implementation in December 2026. The project entered the Environmental Impact Assessment System (SEIA) via an Environmental Impact Declaration (DIA) last October. The declared project type includes high-voltage transmission lines and substation facilities.

According to the plan, the Black BESS energy storage system will consist of 315 battery containers distributed across 58 substation centers. It will also be equipped with 1,890 power conversion systems and 116 distribution transformers. The related facilities will be constructed on a 6.37-hectare plot adjacent to the Roncacho substation, accessible via Ruta 5 and the Minera Pampa Camarones road. Underground transmission lines will be used to connect to the National Electric System (SEN).

Once operational, the Black BESS energy storage system can store electricity during low-demand periods such as daytime and release power to the grid during peak consumption hours in the afternoon and evening. This aims to reduce renewable energy curtailment and enhance the flexibility of the power system, particularly in regions with high solar penetration. The project has an estimated construction period of 16 months and a service life of 25 years. During the construction phase, it will employ an average of about 72 workers, with a peak of 92. The operational phase will require 5 to 8 personnel. The project received environmental support from AG Energía and engineering support from Anabática Renovables. The RCA was granted after an assessment process lasting approximately six months.
