Sungrow has been chosen by Verano Energy to supply a 152MW/606MW-hour (MWh) battery energy storage system (BESS) for the Observatorio project in Chile.

The project will use Sungrow's PowerTitan 2.0 ESS solution and the battery facility is designed for a four-hour duration.

The agreement also provides for a 25-year long-term service agreement to maintain and support the system.

The Observatorio project will combine a 135MW solar photovoltaic (PV) plant, which will be equipped with Sungrow SG350HX-20 inverters, with the BESS.

Sungrow LATAM regional director Gonzalo Feito said: "We are proud that Verano Energy has entrusted Sungrow with the supply of the energy storage solution for the Observatorio project.

"This agreement reinforces our commitment to developing high-performance energy infrastructure and accelerating the energy transition in Chile."

According to Verano Energy, this approach aims to improve the stability of Chile's power system and increase the integration of renewable energy sources.

The company notes that the initiative contributes to advancing infrastructure aimed at supporting Chile's energy transition.

Verano Energy chief operating officer Tomás Anuch said: "Observatorio represents another step in strengthening Verano Energy's position as a key player in renewable energy generation across the region.

"The integration of storage allows us to unlock the full potential of our solar resource, provide greater flexibility to the power system and deliver solutions that meet the needs of a market increasingly focused on renewable energy integration.

"Having a technology partner such as Sungrow also gives us the confidence to develop a project that meets the highest standards of performance and reliability."

In addition to delivering the energy storage system, Sungrow will be responsible for providing long-term service over 25 years, with the aim of ensuring the operational availability and reliability of the facility.

The use of large-scale energy storage reduces curtailment, optimises solar generation and offers operational flexibility for the electricity network.

In June 2026, Sungrow, along with its partner Sunotec, commissioned a 150MW/600MWh BESS in Nova Zagora, Bulgaria.
