en.Wedoany.com Reported - A new renewable energy generation project equipped with an energy storage system is set to be added in Chile's Antofagasta Region. The Parque Fotovoltaico con Capacidad de Almacenamiento Valle de las Estrellas (Valle de las Estrellas Solar PV and Storage Plant) has received environmental approval, with plans to be built in the city of Calama at an investment of $19.8 million.

Developed by Valle de las Estrellas Solar SpA, the project involves the construction and operation of a photovoltaic plant with an installed capacity of 18 MWp, composed of approximately 40,000 solar modules, capable of injecting up to 9 MW of alternating current into the National Electric System (SEN).

One of the project's core components is a battery energy storage system (BESS) with a total capacity of 120 MWh, used to store electricity generated during the day, which can be dispatched during peak hours or at night.

The project covers an area of approximately 35.37 hectares, located about 7.9 kilometers from the city of Calama. The site selection fully leverages local solar radiation conditions and the proximity to existing power infrastructure. The infrastructure includes five substations, a 23 kV transmission line approximately 5.3 kilometers long, as well as internal roads, operational facilities, and monitoring and control systems.

The energy storage system consists of 36 battery containers, each with a capacity of 3.34 MWh, to optimize the efficiency of renewable energy utilization.

According to the environmental assessment, the construction phase is scheduled to begin in November 2026 and last eight months, with commercial operations expected to start in July 2027. The project's design life is estimated to exceed 41 years, covering the construction, operation, and closure phases. The maximum workforce during construction will be 75 people, while the operational phase is expected to have a fixed staff of 6 people.
