28MW x 4 hours! South America's Largest Energy Storage Benchmark is Born

In the Atacama Desert of northern Chile, an energy base gleaming with technological brilliance is quietly emerging. As one of the largest battery energy storage projects in South America, this super energy storage system, with a total capacity of 228MW and a storage duration of 4 hours, is becoming a new benchmark in the renewable energy sector.

SMA

Photovoltaic Complementation and Core Technology Integration

The project perfectly complements the existing 220MW Diego de Almagro Sur photovoltaic (PV) power plant. Since 2022, this PV plant has been using SMA technology to provide a stable supply of solar power to the surrounding area. The newly added energy storage system will further enhance the utilization efficiency and reliability of clean energy.

The project's core competitiveness comes from the integrated application of cutting-edge technology: 67 SMA MVPS (Medium Voltage Power Station) units, each equipped with the industry's most advanced SiC-MOSFET technology in the Sunny Central Storage 4400 UP-S inverters. This technological configuration not only improves energy conversion efficiency but also significantly extends the equipment's service life.

Stabilizing Control System Bolsters Energy Transition

To ensure the precise dispatch and safe operation of the entire energy storage system under complex working conditions, SMA has provided its Power Plant Manager (PPM), a control system specifically developed for large-scale energy storage projects. The full-chain technical support, from photovoltaic power generation to energy storage dispatch, endows this desert energy project with distinct intelligent and efficient characteristics.

As the global energy transition accelerates, Chile, with its abundant solar resources, is becoming a core hub in the Latin American clean energy market. The implementation of this giant energy storage project will not only enhance the stability of the local power grid but also provide a valuable technical model and practical experience for the large-scale development of renewable energy in South America.
