Experience across utility‑scale projects worldwide

In Chile, Enertis Applus+ has supported some of the country’s largest BESS projects by delivering comprehensive supply inspection and quality assurance services. For Grenergy’s Teno (838 MWh), Planchón (360 MWh) and Tamango (168 MWh) BESS projects, the company carried out manufacturing oversight and FAT witnessing of the BESS integrator, as well as FAT witnessing of key Balance of System (BOS) components, including power conversion systems and medium‑voltage transformers. These activities enabled the verification of manufacturing quality, functional performance and compliance with technical specifications prior to equipment delivery, reducing risks at critical stages of the project.

In other key markets, such as Australia, Enertis Applus+ has also delivered independent quality assurance and quality control services. For ACEN Australia’s New England project (400 MWh), the company carried out factory audits, monitoring of manufacturing processes and FAT witnessing of BESS containers and BOS equipment.
